Mrmuehle: DE link corrected

{{Resources}}
A label serves as a spacer on a Moodle course page.It can be used to add text,images, multimedia or code in between other resources in the different sections. It is a very versatile resource and can help to improve the appearance of a course if used thoughtfully. Banners or descriptions may be added to labels to distinguish between and highlight different areas.

On the other hand, over-use of multimedia (sound,video)in labels can slow down the loading of a course page.

Upgrading

2011-10-09T11:10:39Z

Mrmuehle: added a hint for cron users

Moodle is designed to upgrade itself from one version to the next. The procedure is
# [[Site backup|Back up everything]].
# Replace the old version of the code with the new one.
# Visit the [[Site_administration_block#Notifications|administrator notifications]] link, which triggers Moodle to self-update.
These steps are explained in more detail below.

Sometimes there are specific considerations when upgrading to a particular version. See the [[dev:Releases|Releases page]] for more information on this. You also have to be more careful if you have installed additional plug-ins or customised the code.

See this tutorial if you are [http://ic.eflclasses.org/tutorials/howtoupgrademoodlewithcpanel.swf upgrading Moodle on cpanel]. It is a bit rough around the edges and is a little dated, but you should get the idea.

There is also a separate page about [[Ubuntu_Debian_Upgrades|upgrading Moodle if you installed it using the Ubuntu/Kubuntu/Debian package manager]].

__TOC__

When upgrading a Moodle installation you should follow these steps:

==Before you upgrade your site for real==

You are strongly advised to make a copy of your entire Moodle site onto another computer (see [[Moodle migration]]) and run the upgrade there to verify it will work.

==Check the requirements==
Spend some time re-reading the [[Installing Moodle | installation documentation]] and documentation for the new version. Check the system requirements for the target version you want to upgrade-to in ''Administration > Server > [[Environment]]''.
==Put your Site into Maintenance Mode==
Before you begin upgrading your site, you should put it into [[Maintenance_mode | Maintenance Mode]] to stop any non-admin users from logging in.

== Backup important data ==
See [[Site backup]] for more specific information.

There are three areas that should be backed up before any upgrade:
#Moodle software (For example, everything in server/htdocs/moodle)
#Moodle uploaded files (For example, server/moodledata)
#Moodle database (For example, the SQL or Postgres database)

Experienced site administrators know that it is a best practice (a very good idea) to make a backup of any production system before a major upgrade. In fact, it is a good idea to automate your server to backup your Moodle installation daily. Most upgrades on sites that have used the standard Moodle packages (no contributed code and no little tweaks to the php files), will not have any major issues with the upgrade process.

:''TIP:'' One more time, "do not risk what you can not afford to lose": do regular backups, make sure it is really backed up and know how to restore a backup!

== Install the new Moodle software ==
Upgrading can be a simple process or a more complicated process. Sites that have not used contributed code and are migrating from say Moodle 1.x.1 to 1.x.3 '''should''' not have a problem. However, we still recommend that with any production server that you have made a successful backup of the MySQL database, the moodledata directory and the moodle program folders and files.

*Do not overwrite an old installation unless you know what you are doing ... sometimes old files can cause problems in new installations. Review the backup section above.

=== Standard install package ===
Having read the cautions about backups, download a copy of the standard install package. Here is a set of simple instructions for an average site.
*It is probably a good idea to use the [[Site administration block]]>Server>Maintenance mode to prevent user activity as the site upgrades.
*Having moved your old Moodle software program files to another location, unzip or unpack the upgrade file so that all new the Moodle software program files are in the location the old files used to be in on the server. Moodle will adjust SQL and [[Moodledata directory|moodledata]] if it needs to in the upgrade.
*Copy your old [[Configuration file|config.php file]] back to the new Moodle directory.
*If you had added any custom plugins or themes into your Moodle you can add them to the new code. It is important to check that you get the correct version for your new version of Moodle. You should check in the optional plugins database. Be particularly careful that you do not overwrite any code in the new version of Moodle. If you are upgrading to Moodle 2.0 or newer, note that all optional plugins and themes required a significant rewrite and most do not have 2.0 versions (yet).
*Use the notification link in the site administration to start the upgrade process. You will see a series of lines or screens indicating progress.
*After a successful upgrade, turn off the maintenance mode, so your users can get into the site.

=== Using a downloaded archive ===
In some installs, the site administrator may overwrite the Moodle code with a backup copy. Or create a new clean install copy of Moodle, then restore an archive (via a compressed file or parts of a saved set of Moodle code files and folders).

*Do not overwrite an old installation unless you know what you are doing ... sometimes old files can cause problems in new or "cleaned" installations. The best way is to rename the current Moodle code directory (for example rename "moodle" to "moodleold"), then unpack the new Moodle archive into the old location (for example, a new directory called "moodle").

====Linux====
mv moodle moodle.backup
tar xvzf moodle-1.1.tgz

Next, copy across your config.php, any other plugins such as custom themes, and your .htaccess file if you created one ('''check that optional/custom plugins are the correct version for your new Moodle first'''):

cp moodle.backup/config.php moodle
cp -pr moodle.backup/theme/mytheme moodle/theme/mytheme
cp -pr moodle.backup/mod/mymod moodle/mod/mymod

Don't forget to

sudo chown www-data moodle/config.php

If you use cron, take care that cron.php is executeable and uses the correct php command:
chmod 740 admin/cli/cron.php (some configurations need chmod 750)
copy the first line from cron.php (if it looks like '#!/usr/local/bin/php' or '#!/usr/local/bin/php5.3', no need to copy '<?php')

if necessary.

where www-data is whatever user the Apache user is on your system. This is often 'apache' or 'www'.
You can find out by doing 'ls -l' in your /var/www/moodle folder (or wherever your moodle site is)
and then looking at the owner and group.

so you may see something like

ls -l
...lots of lines...
-rw-r--r-- 1 apache system 784 Jun 28 2007 config.php
...lots more lines...

so the owner is apache and the group is system.

To replicate this on your new system you can do 'chown apache:system config.php'

or to do a whole group do

chown apache:system ./*

and recursively

chown -R apache:system ./*

=== Using CVS ===

You can use CVS for updating or upgrading your Moodle.
First you need to do a CVS checkout in your (empty) Moodle root directory.

You can use any of our [[CVS_for_Administrators#CVS_Servers|CVS Mirror servers]]. Just replace '''SERVER.cvs.moodle.org''' in the instructions below with the name of the mirror server you chose!.

====For Linux servers====

To do a CVS checkout of Moodle, you first have to logon to the Moodle CVS server.

<nowiki>cvs -d:pserver:anonymous@SERVER.cvs.moodle.org:/cvsroot/moodle login</nowiki>
No password for anonymous, so just hit the Enter button.

Go to the directory where you want the Moodle root to come and type

<nowiki>cvs -z3 -d:pserver:anonymous@SERVER.cvs.moodle.org:/cvsroot/moodle co -r MOODLE_18_STABLE moodle</nowiki>
(where MOODLE_18_STABLE is the desired version)

To update, just go into the Moodle root directory and update to the new files:

cvs update -dP
To update to a new version type in the following and change 18 to whatever newest version upgrade number is
cvs -Q update -dP -r MOODLE_18_STABLE

Make sure you use the "d" parameter to create new directories if necessary, and the "P" parameter to prune empty directories.

====For Windows servers====

You can use Tortoise CVS to do the initial checkout and the updates.

If you have been editing Moodle files, watch the messages very closely for possible conflicts. All your customised themes and non-standard plugins will be untouched.

Do not forget to trigger the install process in the site administration block (see below).

=== Using Git ===

You can use [[Git]] for updating or upgrading your Moodle.
First you need to do a Git checkout in your (empty) Moodle root directory.

See [[Git for Administrators]] for further details.

== Finishing the upgrade ==

The last step is to trigger the upgrade processes within Moodle.

To do this just visit the [[Site administration block]] admin page (or ''<nowiki>http://example.com/moodle/admin</nowiki>'') and the "Notifications" link.

Moodle will automatically detect the new version and perform all the SQL database or file system upgrades that are necessary. If there is anything it can't do itself (very rare) then you will see messages telling you what you need to do.

Assuming all goes well (no error messages) then you can start using your new version of Moodle and enjoy the new features!

:''TIP:'' Use the site administration block>Server>Maintenance mode to prevent users from changing data during the upgrade.
:''TIP:'' If you are running a large scale Moodle site (e.g. have more tha 10,000+ courses and 40,000+ users), make sure that you do your own performance profiling testing. Post a thread or check the [http://moodle.org/mod/forum/view.php?id=28 Installation problems forum] and check [[Tracker]] for potential issues.

== Verify the upgrade (optional) ==

If you wish to confirm that the database definitions in the upgraded database match the definitions of a new, clean install (which they should) you might like to look at [[Verify Database Schema]].

==Upgrading more than one version==

In general, it is recommended to upgrade via the newest of each major version of Moodle, for example 1.7 -> 1.9. An exception to this is when upgrading from 1.5 or 1.6, when it is recommended that 1.7 and 1.8 are skipped, in other words upgrade 1.5 -> 1.6 -> 1.9. (The main reason for this recommendation is that the default roles settings obtained when upgrading to 1.7 are not ideal for 1.8 onwards, 1.8 has problems with groups, etc.)

Mrmuehle: /* Hint: */

== Creating a new page ==

To create a new page, either type the page name between double square brackets <nowiki>[[page name]]</nowiki> OR you can select '''New''' from the Wiki menu PROVIDED if you have access to the Navigation block.

=== Hint: ===
The trick about using the Navigation block '''New''' option under your Wiki is that you will still need to copy and paste the name of the new page onto the immediate parent page and surround it with double brackets. This creates a link to your new page and makes it accessible from the main Wiki page.
Otherwise nobody will recognise the so called lost new page.

== wiki editing in general ==

Depending on the type of the wiki, there are several possibillities to edit the page.
But don't worry: The best thing of a wiki is, thatnothing is lost. The old version will be there - and if someone changes your version of the page - your version will also be there.

== markup language ==
You miss all the formatting you know from other moodle activities?
Thats because the wiki-type of your wiki is e.g. nwiki.

here are some markup hints from the early moodle 2.0 days: (nwiki promised to be close to [https://docs.moodle.org/20/en/Help:Editing mediawiki-markup]

Mrmuehle:

Setting up Eclipse

2008-05-05T06:15:04Z

Mrmuehle: /* Resetting the branch information */

[http://www.eclipse.org/ Eclipse] is an IDE originally designed for Java, but now with plugins for many languages including PHP. It has lots of very powerful features, and it is the editor that some Moodle developers like to use. Other (more) popular choices are vim and emacs.

However, Eclipse is not the easiest program in the world to get started with, so I'm going to take you through it step by step. These instructions assume Eclipse 3.2, the current version at the time of writing. It should not change much between releases.

This article started off as a brain-dump by [[User:Tim Hunt|Tim Hunt]]. Since then, several other people have worked through it and made corrections, so the information here should be pretty accurate.

==Prerequisites==

Eclipse is written in Java, so I recommend getting the latest Java runtime environment from http://java.com/ for maximum speed and reliability.

Eclipse is quite big, so I recommend lots of memory in your computer. I have used it on Windows, MacOS X and Linux, in each case with 1GB of memory, and that is plenty.

==Installing Eclipse==

Go to http://www.eclipse.org/downloads/. Click on the link corresponding to your operating system where it says '''Eclipse Classic'''. Choose a Mirror, and wait for the ~100MB download.

You will notice that what you have got is a zip file (unless your system automatically decompresses it for you).

On Windows, unzip it into '''C:\Program Files''' (all the files go into an '''Eclipse''' folder there). Then look in the Eclipse folder and drag Eclipse.exe to the Start menu/Desktop/Quicklaunch bar to make a shortcut for starting it.

On MacOS, unzip and copy the Eclipse folder into Applications. Go into the Eclipse folder and drag the Eclipse app to the Dock for ease of launching.

On Linux, unzip somewhere suitable, and make an easy way to launch it.

==The first time you run Eclipse==

The first time you launch Eclipse it does a bit of setup stuff, for instance, it create a '''workspace'''. This is where it stores the things you are working on. The default location is sensible on all platforms, so use that.

For some reason, every time you start Eclipse, it asks you which workspace you want to use. I have never seen the need to have more than one, so I recommend turning on the checkbox that says "Use this as the default and do not ask again".

Another thing that happens the first time you run Eclipse is that you arrive at a welcome screen. This has links to various bits of help, which you can read if you like, but you probably don't need to if you are following these instructions. So find the button on the welcome page that closes it and gets you to the main Eclipse screen.

==Installing the necessary plugins==

By default, Eclipse comes with the Java tools. For everything else you will need to install some plugins.

If you are sitting behind a web proxy, from the '''Window''' menu choose '''Preferences ...'''. Choose '''Install/Update''' from the tree view on the left, and enter the proxy information in the boxes on the right. If you aren't behind a proxy, ignore this step.

From the '''Help''' menu choose '''Software Updates -> Find and Install'''.

On the first screen of the wizard, make sure that "Search for new features to install" is selected, then click '''Next >'''.

The next screen is a list of upgrade sites to check. You need to add one to the list, so click the '''New Remote Site ...''' Button.

In the pop-up dialog, give the remote site a name like '''PHPeclipse Update Site'''; set the URL to http://phpeclipse.sourceforge.net/update/releases/; then click '''OK'''.

''Note, there is now also another PHP editor for Eclipse. The update URL ishttp://download.eclipse.org/tools/pdt/updates/. I am just trying it--[[User:Tim Hunt|Tim Hunt]] 11:39, 7 November 2007 (CST)''

Back in the wizard, turn on just two things in the box "Sites to include in search":
* Your newly created '''Phpeclipse Update Site'''; and
* the one called '''Europa Discovery Site''' (or possibly '''Callisto Discovery Site'''.
Then click '''Finish'''.

It goes off sees what updates are available at those sites. As it does so, it may occasionally pop up a dialog asking you to choose a mirror. Each time, select a sensible one.

Eventually, you get to a new wizard for selecting and installing the updates you want. The ones you want (you may have to search the tree structure) are, '''PHPeclipse''' (from your newly created PHPEclipse Update Site) and all the '''Web Standard Tools (WST)''' (usually under Callisto Discovery Site --> Web and J2EE Development).

Next, and very importantly, you must click the '''Select Required''' button which should resolve dependencies and remove the warning message you are probably worrying about. Then you can click the '''Next >''' button.

Read and agree to all the license agreements. Then click '''Next >'''.

Click '''Finish''', and wait for the plugins to download.

Once the downloads have finished, a warning will pop-up telling you that all the plugins you downloaded are not digitally signed. The Eclipse Foundation build digital signing of plugins into their architecture as a security measure, and then did not sign any of their own plugins! Anyway, click the '''Install All''' button.

Finally, a window will pop up asking you to restart Eclipse. Do so.

==Setting the preferences for Moodle development==

Now go to the '''Window''' menu, and choose '''Preferences ...''' ('''Eclipse''' menu on Mac OS X).

The Eclipse preferences are immense, with a tree view on the left, which selects which screen to display on the right. Don't panic, we'll guide you through it.

===General settings===

If you have strong feelings about fonts (I would hate to edit code an anything except Andale Mono), choose '''General -> Appearance -> Colors and Fonts''' from the tree on the left. Then on the right look under '''Basic''' and change '''Text Font'''. All the other editor font settings will inherit from this, so this is probably the only one you have to change.

Under '''General -> Content Types''', select PHP Source File, and add '''*.html''' to the box at the bottom.

Under '''General -> Editors -> File Associations''', if it is not already there, add '''*.php''' to the top box. With '''*.php''' selected in the top box, make sure '''PHP Editor''' is set to default in the bottom box. With '''*.html''' selected in the top box, select '''PHP Editor''' in the bottom box and click the '''Default''' button to change it, because in Moodle, most HTML files actually contain PHP code.

If you use a web proxy, enter the details under '''Internet -> Proxy Settings'''. (Yes, I know you have entered them somewhere else before. Now you have to enter them again here. I don't know why. You just do.)

===PHP Settings===

These are all hidden under the '''PHPeclipse Web Development''' bit of the tree.

Under '''PHPeclipse Web Development -> Browser Preview Defaults''', turn off both checkboxes.

Under '''PHPeclipse Web Development -> PHP''', on the '''Appearance''' tab, set '''Displayed tab width''' to 4.

Under '''PHPeclipse Web Development -> PHP''', on the '''Appearance''' tab, check '''Show line numbers''' to display line numbers in the left margin (optional). NOTE.- When you are editing a PHP file, you could left-click in the left margin and tick the '''Show Line Numbers''' line in the contextual menu. However, this toggle only applies to plain text files, ''not'' to HTML or PHP files. The only place where you can toggle line numbers on/off for such files is in the PHP/Appearance menu.

Under '''PHPeclipse Web Development -> PHP''', on the '''Typing''' tab, turn off all the options except '''Pasting for correct indentation''', '''Insert spaces for tab''' and '''Close PHPdocs and comments''' and '''Remove trailing spaces on editor save'''. It would be nice to turn on more of these options, but most of the rest don't work very well.

Under '''PHPeclipse Web Development -> PHP -> Formatter''', on the '''New Lines''' tab, turn on '''Clear all blank lines'''.

Under '''PHPeclipse Web Development -> PHP -> Formatter''', on the '''Style''' tab, turn off '''Indentation is represented by a tab'''.

Under '''PHPeclipse Web Development -> PHP -> Templates''', I like to define a new template to help with debugging:
;Name
:dump
;Description
:Dump a PHP variable
;Pattern
<pre>print_object(${word_selection}${cursor}); // DONOTCOMMIT</pre>
You can do other useful things with templates too. Here are two more I use:
<pre>debugging("'${word_selection}${cursor}'"); // DONOTCOMMIT</pre>
<pre>$$string['${word_selection}${cursor}'] = '.';</pre>
That is, a simple debug message with a stack trace, and a new language string.

There is a really stupid bug. Under '''PHPeclipse Web Development -> Project Defaults''', you would like to add "." to the '''Include Paths''', but you can't using the GUI. You will have to edit one of the Eclipse config files by hand. So
# Note down the path to your Eclipse profile. On Windows it will be something like '''C:/Documents and settings/XXXX/workspace''', and on Unixy systems something like '''~/workspace'''.
# Close Eclipse.
# Open the file '''net.sourceforge.phpeclipse.ui.prefs''' that is in the directory '''(your workspace)/.metadata/.plugins/org.eclipse.core.runtime/.settings''' in a text editor.
# Look for a line in the file that starts '''_php_include_paths=''' If it is not there, add it at the end.
# Change this line to say '''_php_include_paths=.'''
# Run Eclipse again.

===SSH2===
Information about generating SSH2 keys for the purpose of connecting to cvs.moodle.org can be found here at https://docs.moodle.org/en/Development:SSH_key , but please finish reading this section before reading that material.

The Eclipse installation has its own SSH client plugin so you do not have to use a separate ssh client in connection with your use of Eclipse (this is one reason you will be using extssh below, instead of just ext, however, if you wish you may alter the configuration to use an external client but please post news of your success and configuration). See, http://www.jcraft.com/eclipse-cvsssh2/ , for additional information on this plugin.

Please note that Eclipse is fully equipped to generate ssh2 rsa and dsa keys as well as import keys. You may encounter issues with passphrases that are too long (a bug reportedly fixed but which may still in fact be present) and some issues with using keypairs generated by other applications have been seen, so it may be best to generate a key pair with Eclipse. Additional details on how to do this will be added.

Sourceforge, at http://sourceforge.net/docs/F02/ , provides instructions on how to create a SSH key for it's CVS (remember, Moodle does not use sourceforge for its CVS now and you will need to generate keys for cvs.moodle.org, not sourceforge). This is mentioned by way of general explanation, not for the purposes of providing instructions on how to generate your keys for Eclipse. To make use of the public key, login to Moodle.org and add it via the Update My Developer Information tab under CVS Developers (http://moodle.org/cvs). Remember, public keys provided to Moodle must be in the Openssh format.

===CVS Settings===

These are all hidden under the '''Team''' bit of the tree.

Under '''Team -> CVS -> SSH2 Connection Method''', you can set up a public/private key pair. If you do this, you won't have to keep typing your password when doing CVS operations.

The rest of the ones in this section are personal preferences, but I recommend them because the default settings are very irritating.

Under '''Team''', set '''Perspectives''' to '''None'''.

Under '''Team -> CVS -> Annotate''' set '''Use Quick Diff annotate mode for local file annotations''' to '''Yes''', and '''Open perspective after a 'Show Annotations' operation''' to '''No'''.

Under '''Team -> CVS -> Label Decorations''', switch to the '''Icon Decorations''' tab and turn on all the settings, and then on the '''Text Decorations''' tab change both '''File Decoration''' and '''Folder Decoration''' to be just '''{name}'''.

===Web and XML settings===

Foreach XXX in CSS, HTML, Javascript, XML:

Under '''Web and XML -> XXX Files ->XXX Source''', choose '''Indent using spaces''' and '''indentation size''' 4.

==Checking out the Moodle code==

From the '''File''' menu, choose '''New -> Project ...''', then click '''Next >'''.

In the wizard that pops up, choose '''CVS -> Projects from CVS''', then click '''Next >'''.

Select '''Create a new repository location''', then click '''Next >'''.

Fill in
<div style="float: right; border: 1px solid orange; padding: 0 1em;">
For anonymous CVS access use
;Host
:XX.cvs.moodle.org
where XX.cvs.moodle.org is one of [[CVS_for_Administrators#CVS_Servers|these mirrors]]
;Repository path
:/cvsroot/moodle
;User
:anonymous
;Password
:(leave blank)
;Connection type
:pserver
</div>
;Host
:cvs.moodle.org
;Repository path
:/cvsroot/moodle
;User
:(your Moodle CVS username)
;Password
:(if you set up the SSH2 key thing in preferences, leave this blank, otherwise, type in your Moodle CVS password.)
;Connection type
:extssh
(CVS experts, if you are confused by that last one, know it is an Eclipse-specific thing.) Then click '''Next >'''.

On the next screen of the Wizard, choose '''Use an existing module'''. Wait a moment, then select '''moodle''' from the list. Click '''Next >'''.

On the next screen, make sure the option '''Check out as a project configured using the New Project Wizard''' is selected, then click '''Next >'''.

Click '''Refresh Tags''', then choose the branch you want. For now leave it set to '''HEAD'''.

Click '''Finish'''.

Now you will find yourself back at the start of the '''New Project''' Wizard. This is because of the option you chose three paragraphs ago. This time you should select '''PHP -> PHP Project''', then click '''Next >'''.

Make up a project name. '''moodle''' would be sensible.

Click '''Finish''', and wait while all the moodle files are checked out of CVS.

Once it has finished, it will probably ask you if you want to switch to the PHP perspective. Answer '''Yes'''.

If you also need another branch (1.6, 1.7, 1.8, ...) repeat all the other steps with a few changes:
* This time you can choose '''Use an existing repository location''' instead of typing all the sourceforge CVS details again.
* Select the appropriate branch. If you don't see the branch you want, see [https://docs.moodle.org/en/Development:Setting_up_Eclipse#Resetting_the_branch_information this Troubleshooting tip].
* Use a different project name (e.g. moodle16, moodle17, etc.).

==Let your development web server know where your files are==

Either by editing you web server's config files, or using a symbolic link. Make sure your webserver can see your new working set of files at a sensible URL, so you can test the code you are working on.

==Quick tour of some cool features, and remaining configuration changes==

I find the default workbench setup is pretty good. Here is a quick guide to some of the bits.

===Navigator===

To the left is the '''Navigator'''. This is a tree view of all your files. If you double-click on a file, it opens in the editor in the middle. Try opening '''course/lib.php''' now. You will notice that it comes up nicely syntax-hightlighted.

===Error highlighting===

In the middle of the file, just type any old text, for example "I like Eclipse". Obviously, this is not valid PHP syntax, and Eclipse will notice this, and put a red underline under it. Also, by the scrollbar is a ruler with a red mark in it to show the error.

You will see some yellow marks lower down the ruler. There are warnings. Click on one, and you will be taken to where that warning is in the file. Hover your mouse over the warning, and you will get a tooltip explaining what the problem might be.

Save the edited file. (Don't worry that it is broken, we'll clean up the mess later.) Notice that a red error marker is added to the file in the navigator, so you can see that there is a problem. Also, error markers are added to the course folder, and the whole project, so you could see there was an error even if the navigator tree was collapsed.

You will probably find lots of warnings that the config.php file can't be found. In the navigator, find the file '''config-dist.php'''. Do '''Copy''' then '''Paste''' and choose to call the new file '''config.php'''. Edit this new config.php as normal. You should fine that most of the include file warnings have gone now.

Notice also that there is another marker on each file icon. A little yellow cylinder on most files, but a white-on-brown star on the one you have edited. This is telling you the CVS status of each file. The brown stars are changes you have made but not checked in yet.

===Outline===

Over to the right is the Outline view. This shows a list of functions and classes defined in this file. By default, they are listed in the same order as in the file, but if you click on the '''az''' toolbar button, they are sorted into alphabetical order.

Click on the function name '''add_course_module''' in the Outline. You will see that the editor scrolls to the definition of that function.

===Code navigation===

In that function, hover the mouse pointer over the function name '''insert_record'''. After a while, the documentation for that function will appear in a big tooltip.

Hold down CTRL, move the mouse pointer over the function name '''insert_record''', then click. Eclipse should load '''dmllib.php''', and scroll you to where this function is defined.

In the main Eclipse toolbar, there are forward and back arrows like in a web browser. Click back now to get back to '''course/lib.php'''.

===Open resource===

From the '''Navigate''' menu, choose '''Open Resource...'''. In the dialog that pops up, start typing a filename for instance type '''moodlel'''. In the box in the middle of the dialog, you will see it list all the files in the project whose names start that way. At the bottom is a box which lists the different folders that contain a file with that name. This can be a very quick way of opening files with fairly unique names like moodlelib.php, without having to click through the levels of the navigator tree. Of course, it is not so useful for an index.php file! Click OK now to open moodlelib.php. (It would actually work if you just did CTRL + Shift + R, moodlel, Enter.)

===Multi-file search===

Scroll down moodlelib a little bit, and double click on the name of the constant '''MOODLE_INTERNAL''' where it is defined, so that the text is selected. Then, from the '''Search''' menu, choose '''Search...'''. Notice that the '''Containing text''' box has already been filled in for you with the text you just selected. Of course you can just type text into this box without selecting it first. Notice that you can do regular expression searches, but leave that turned off for now. In the '''File name patterns''' box type '''*.css, *.html, *.inc, *.js, *.php, *.xml'''. (This is the most useful general setting for working on moodle. Eclipse will remember this setting, so you only have to enter it once.) Click '''Search'''.

The search results will appear in a new view underneath the editor. That view has a toolbar with yellow up and down arrows. Click the down arrow a few times and it will take you to the first few matches in the code, opening the relevant files as necessary.

===Synchronize view===

I think this is my favorite feature. From the '''Window''' menu, select '''Show View -> Other...'''. In the dialog that pops up, select '''Team -> Synchronize''', then click '''OK'''.

This opens the Synchronize view below the editor. The view has a toolbar. Click on the first toolbar button, which pops up the Synchronize wizard.

On the first screen, there will probably only be one option: '''CVS'''. Make sure that is selected, then click '''Next >'''.

Under '''Scope''', choose '''Workspace''', then click '''Finish'''.

Wait while it talks to the CVS server. After a while, you will see that the Synchronize view lists course/lib.php, and something called '''.project.... That is, it is listing just the files you have edited, but not checked in yet.

'''.project''' is something that belongs to Eclipse that we don't care about. So select it and bring up the context menu, and choose '''Add to .cvsignore...'''. In the dialog that pops up, choose the top option, then click '''OK'''. Then you will find the Synchronize view shows you a '''.cvsignore''' file that you aren't interested in, so add that to .cvsignore too!

If you double-click on '''course/lib.php''' here, you will see that it opens the compare editor, which is a nice graphical display of the changes in this file.

If you select a file or files here, then bring up the context menu, you will see the option to '''Commit...''' the changes. (But don't do that now!). This is the easiest way to commit things in Eclipse.

However, our changes were rubbish, so we want to undo them. So open the context menu again, and choose '''Override and Update'''. This checks a clean copy of the file out of CVS, removing our changes.

Note that the easiest way to do an ordinary CVS Update is to select the top-level project-folder in the Navigator view on the left, open the context menu, and choose '''Team -> Update'''.

That's all the really important features. I sure you can learn everything else on your own. An you could always read the built in help!

===Creating a patch===

In the synchronise view, right click on an item (file or folder) and choose '''Create Patch...'''. Or in the navigator, right click on an item and choose '''Team -> Create Patch...'''.

This brings up a two-page wizard. On the first page you can select where you want the patch made. For small patches it can be useful to create them on the clipboard, but normally you will want to save them in a file.

On the second page, you can set some options, but normally you don't need to change the defaults which are '''Unified''' diff format, and Patch root set to '''Workspace'''. Well, sometimes it is helpful to change the second one to '''Project''' but it is not important.

There is a corresponding apply patch wizard that you can use to apply a patch to a project.

===Switching to another branch or version===

Suppose you have been using a check-out of HEAD from CVS, and then as the 1.9 release approaches, the MOODLE_19_STABLE branch is created, and you want to start following that instead.
# Right click on the moodle project in the navigator view, and select '''Team -> Switch to Another Branch or Version ...'''.
# choose the second radio button: '''Select the tag from the following list'''.
# If the branch you want is not in the '''Matching tags''' box, see [[Development:Setting_up_Eclipse#Resetting the branch information|Resetting the branch information]] below.
# Select the branch you want and click '''Finish'''.

==Troubleshooting==

Some tips on how to solve common problems that may crop up.

===Resetting the branch information===

Every now and then, Eclipse may lose information on the branch tags it knows about. Hitting refresh tags may fix it, but if not, try the following:

#Bring up the tag dialogue (example using "Team / Switch to Another Branch or Version").
#Click on Configure tags ... (not Refresh tags).
#Select config-dist.php in the top left box (if this is a Moodle checkout).
#Click Add Checked tags.
#Click OK.
#Then you will have all tags.

===Error loading php files after Ubuntu 7.04 Install===

A java issue with Ubuntu 7.04 may cause an error when you attempt to load php pages. Refer to:
http://www.plog4u.org/index.php/Using_PHPEclipse_:_Installation_:_Installing_PHPEclipse for details about how to fix this in Ubuntu 7.04.

After upgrading from Ubuntu 7.04 to 7.10, I had to go in and re-edit the /etc/eclipse/java_home file in order to get the CVS functions to work and be able to open PHP files. When I tried to do a CVS update I initially received an error about org.eclipse.team.internal.ccvs.ui.wizards.CheckoutWizard). Everything seemed to work again after reapplying the fix for the aforementioned 7.04 java issue.

[[Category:Developer|Setting up Eclipse]]

Setting up Eclipse

2008-05-05T06:13:53Z

Mrmuehle: /* Resetting the branch information */

[http://www.eclipse.org/ Eclipse] is an IDE originally designed for Java, but now with plugins for many languages including PHP. It has lots of very powerful features, and it is the editor that some Moodle developers like to use. Other (more) popular choices are vim and emacs.

However, Eclipse is not the easiest program in the world to get started with, so I'm going to take you through it step by step. These instructions assume Eclipse 3.2, the current version at the time of writing. It should not change much between releases.

This article started off as a brain-dump by [[User:Tim Hunt|Tim Hunt]]. Since then, several other people have worked through it and made corrections, so the information here should be pretty accurate.

==Prerequisites==

Eclipse is written in Java, so I recommend getting the latest Java runtime environment from http://java.com/ for maximum speed and reliability.

Eclipse is quite big, so I recommend lots of memory in your computer. I have used it on Windows, MacOS X and Linux, in each case with 1GB of memory, and that is plenty.

==Installing Eclipse==

Go to http://www.eclipse.org/downloads/. Click on the link corresponding to your operating system where it says '''Eclipse Classic'''. Choose a Mirror, and wait for the ~100MB download.

You will notice that what you have got is a zip file (unless your system automatically decompresses it for you).

On Windows, unzip it into '''C:\Program Files''' (all the files go into an '''Eclipse''' folder there). Then look in the Eclipse folder and drag Eclipse.exe to the Start menu/Desktop/Quicklaunch bar to make a shortcut for starting it.

On MacOS, unzip and copy the Eclipse folder into Applications. Go into the Eclipse folder and drag the Eclipse app to the Dock for ease of launching.

On Linux, unzip somewhere suitable, and make an easy way to launch it.

==The first time you run Eclipse==

The first time you launch Eclipse it does a bit of setup stuff, for instance, it create a '''workspace'''. This is where it stores the things you are working on. The default location is sensible on all platforms, so use that.

For some reason, every time you start Eclipse, it asks you which workspace you want to use. I have never seen the need to have more than one, so I recommend turning on the checkbox that says "Use this as the default and do not ask again".

Another thing that happens the first time you run Eclipse is that you arrive at a welcome screen. This has links to various bits of help, which you can read if you like, but you probably don't need to if you are following these instructions. So find the button on the welcome page that closes it and gets you to the main Eclipse screen.

==Installing the necessary plugins==

By default, Eclipse comes with the Java tools. For everything else you will need to install some plugins.

If you are sitting behind a web proxy, from the '''Window''' menu choose '''Preferences ...'''. Choose '''Install/Update''' from the tree view on the left, and enter the proxy information in the boxes on the right. If you aren't behind a proxy, ignore this step.

From the '''Help''' menu choose '''Software Updates -> Find and Install'''.

On the first screen of the wizard, make sure that "Search for new features to install" is selected, then click '''Next >'''.

The next screen is a list of upgrade sites to check. You need to add one to the list, so click the '''New Remote Site ...''' Button.

In the pop-up dialog, give the remote site a name like '''PHPeclipse Update Site'''; set the URL to http://phpeclipse.sourceforge.net/update/releases/; then click '''OK'''.

''Note, there is now also another PHP editor for Eclipse. The update URL ishttp://download.eclipse.org/tools/pdt/updates/. I am just trying it--[[User:Tim Hunt|Tim Hunt]] 11:39, 7 November 2007 (CST)''

Back in the wizard, turn on just two things in the box "Sites to include in search":
* Your newly created '''Phpeclipse Update Site'''; and
* the one called '''Europa Discovery Site''' (or possibly '''Callisto Discovery Site'''.
Then click '''Finish'''.

It goes off sees what updates are available at those sites. As it does so, it may occasionally pop up a dialog asking you to choose a mirror. Each time, select a sensible one.

Eventually, you get to a new wizard for selecting and installing the updates you want. The ones you want (you may have to search the tree structure) are, '''PHPeclipse''' (from your newly created PHPEclipse Update Site) and all the '''Web Standard Tools (WST)''' (usually under Callisto Discovery Site --> Web and J2EE Development).

Next, and very importantly, you must click the '''Select Required''' button which should resolve dependencies and remove the warning message you are probably worrying about. Then you can click the '''Next >''' button.

Read and agree to all the license agreements. Then click '''Next >'''.

Click '''Finish''', and wait for the plugins to download.

Once the downloads have finished, a warning will pop-up telling you that all the plugins you downloaded are not digitally signed. The Eclipse Foundation build digital signing of plugins into their architecture as a security measure, and then did not sign any of their own plugins! Anyway, click the '''Install All''' button.

Finally, a window will pop up asking you to restart Eclipse. Do so.

==Setting the preferences for Moodle development==

Now go to the '''Window''' menu, and choose '''Preferences ...''' ('''Eclipse''' menu on Mac OS X).

The Eclipse preferences are immense, with a tree view on the left, which selects which screen to display on the right. Don't panic, we'll guide you through it.

===General settings===

If you have strong feelings about fonts (I would hate to edit code an anything except Andale Mono), choose '''General -> Appearance -> Colors and Fonts''' from the tree on the left. Then on the right look under '''Basic''' and change '''Text Font'''. All the other editor font settings will inherit from this, so this is probably the only one you have to change.

Under '''General -> Content Types''', select PHP Source File, and add '''*.html''' to the box at the bottom.

Under '''General -> Editors -> File Associations''', if it is not already there, add '''*.php''' to the top box. With '''*.php''' selected in the top box, make sure '''PHP Editor''' is set to default in the bottom box. With '''*.html''' selected in the top box, select '''PHP Editor''' in the bottom box and click the '''Default''' button to change it, because in Moodle, most HTML files actually contain PHP code.

If you use a web proxy, enter the details under '''Internet -> Proxy Settings'''. (Yes, I know you have entered them somewhere else before. Now you have to enter them again here. I don't know why. You just do.)

===PHP Settings===

These are all hidden under the '''PHPeclipse Web Development''' bit of the tree.

Under '''PHPeclipse Web Development -> Browser Preview Defaults''', turn off both checkboxes.

Under '''PHPeclipse Web Development -> PHP''', on the '''Appearance''' tab, set '''Displayed tab width''' to 4.

Under '''PHPeclipse Web Development -> PHP''', on the '''Appearance''' tab, check '''Show line numbers''' to display line numbers in the left margin (optional). NOTE.- When you are editing a PHP file, you could left-click in the left margin and tick the '''Show Line Numbers''' line in the contextual menu. However, this toggle only applies to plain text files, ''not'' to HTML or PHP files. The only place where you can toggle line numbers on/off for such files is in the PHP/Appearance menu.

Under '''PHPeclipse Web Development -> PHP''', on the '''Typing''' tab, turn off all the options except '''Pasting for correct indentation''', '''Insert spaces for tab''' and '''Close PHPdocs and comments''' and '''Remove trailing spaces on editor save'''. It would be nice to turn on more of these options, but most of the rest don't work very well.

Under '''PHPeclipse Web Development -> PHP -> Formatter''', on the '''New Lines''' tab, turn on '''Clear all blank lines'''.

Under '''PHPeclipse Web Development -> PHP -> Formatter''', on the '''Style''' tab, turn off '''Indentation is represented by a tab'''.

Under '''PHPeclipse Web Development -> PHP -> Templates''', I like to define a new template to help with debugging:
;Name
:dump
;Description
:Dump a PHP variable
;Pattern
<pre>print_object(${word_selection}${cursor}); // DONOTCOMMIT</pre>
You can do other useful things with templates too. Here are two more I use:
<pre>debugging("'${word_selection}${cursor}'"); // DONOTCOMMIT</pre>
<pre>$$string['${word_selection}${cursor}'] = '.';</pre>
That is, a simple debug message with a stack trace, and a new language string.

There is a really stupid bug. Under '''PHPeclipse Web Development -> Project Defaults''', you would like to add "." to the '''Include Paths''', but you can't using the GUI. You will have to edit one of the Eclipse config files by hand. So
# Note down the path to your Eclipse profile. On Windows it will be something like '''C:/Documents and settings/XXXX/workspace''', and on Unixy systems something like '''~/workspace'''.
# Close Eclipse.
# Open the file '''net.sourceforge.phpeclipse.ui.prefs''' that is in the directory '''(your workspace)/.metadata/.plugins/org.eclipse.core.runtime/.settings''' in a text editor.
# Look for a line in the file that starts '''_php_include_paths=''' If it is not there, add it at the end.
# Change this line to say '''_php_include_paths=.'''
# Run Eclipse again.

===SSH2===
Information about generating SSH2 keys for the purpose of connecting to cvs.moodle.org can be found here at https://docs.moodle.org/en/Development:SSH_key , but please finish reading this section before reading that material.

The Eclipse installation has its own SSH client plugin so you do not have to use a separate ssh client in connection with your use of Eclipse (this is one reason you will be using extssh below, instead of just ext, however, if you wish you may alter the configuration to use an external client but please post news of your success and configuration). See, http://www.jcraft.com/eclipse-cvsssh2/ , for additional information on this plugin.

Please note that Eclipse is fully equipped to generate ssh2 rsa and dsa keys as well as import keys. You may encounter issues with passphrases that are too long (a bug reportedly fixed but which may still in fact be present) and some issues with using keypairs generated by other applications have been seen, so it may be best to generate a key pair with Eclipse. Additional details on how to do this will be added.

Sourceforge, at http://sourceforge.net/docs/F02/ , provides instructions on how to create a SSH key for it's CVS (remember, Moodle does not use sourceforge for its CVS now and you will need to generate keys for cvs.moodle.org, not sourceforge). This is mentioned by way of general explanation, not for the purposes of providing instructions on how to generate your keys for Eclipse. To make use of the public key, login to Moodle.org and add it via the Update My Developer Information tab under CVS Developers (http://moodle.org/cvs). Remember, public keys provided to Moodle must be in the Openssh format.

===CVS Settings===

These are all hidden under the '''Team''' bit of the tree.

Under '''Team -> CVS -> SSH2 Connection Method''', you can set up a public/private key pair. If you do this, you won't have to keep typing your password when doing CVS operations.

The rest of the ones in this section are personal preferences, but I recommend them because the default settings are very irritating.

Under '''Team''', set '''Perspectives''' to '''None'''.

Under '''Team -> CVS -> Annotate''' set '''Use Quick Diff annotate mode for local file annotations''' to '''Yes''', and '''Open perspective after a 'Show Annotations' operation''' to '''No'''.

Under '''Team -> CVS -> Label Decorations''', switch to the '''Icon Decorations''' tab and turn on all the settings, and then on the '''Text Decorations''' tab change both '''File Decoration''' and '''Folder Decoration''' to be just '''{name}'''.

===Web and XML settings===

Foreach XXX in CSS, HTML, Javascript, XML:

Under '''Web and XML -> XXX Files ->XXX Source''', choose '''Indent using spaces''' and '''indentation size''' 4.

==Checking out the Moodle code==

From the '''File''' menu, choose '''New -> Project ...''', then click '''Next >'''.

In the wizard that pops up, choose '''CVS -> Projects from CVS''', then click '''Next >'''.

Select '''Create a new repository location''', then click '''Next >'''.

Fill in
<div style="float: right; border: 1px solid orange; padding: 0 1em;">
For anonymous CVS access use
;Host
:XX.cvs.moodle.org
where XX.cvs.moodle.org is one of [[CVS_for_Administrators#CVS_Servers|these mirrors]]
;Repository path
:/cvsroot/moodle
;User
:anonymous
;Password
:(leave blank)
;Connection type
:pserver
</div>
;Host
:cvs.moodle.org
;Repository path
:/cvsroot/moodle
;User
:(your Moodle CVS username)
;Password
:(if you set up the SSH2 key thing in preferences, leave this blank, otherwise, type in your Moodle CVS password.)
;Connection type
:extssh
(CVS experts, if you are confused by that last one, know it is an Eclipse-specific thing.) Then click '''Next >'''.

On the next screen of the Wizard, choose '''Use an existing module'''. Wait a moment, then select '''moodle''' from the list. Click '''Next >'''.

On the next screen, make sure the option '''Check out as a project configured using the New Project Wizard''' is selected, then click '''Next >'''.

Click '''Refresh Tags''', then choose the branch you want. For now leave it set to '''HEAD'''.

Click '''Finish'''.

Now you will find yourself back at the start of the '''New Project''' Wizard. This is because of the option you chose three paragraphs ago. This time you should select '''PHP -> PHP Project''', then click '''Next >'''.

Make up a project name. '''moodle''' would be sensible.

Click '''Finish''', and wait while all the moodle files are checked out of CVS.

Once it has finished, it will probably ask you if you want to switch to the PHP perspective. Answer '''Yes'''.

If you also need another branch (1.6, 1.7, 1.8, ...) repeat all the other steps with a few changes:
* This time you can choose '''Use an existing repository location''' instead of typing all the sourceforge CVS details again.
* Select the appropriate branch. If you don't see the branch you want, see [https://docs.moodle.org/en/Development:Setting_up_Eclipse#Resetting_the_branch_information this Troubleshooting tip].
* Use a different project name (e.g. moodle16, moodle17, etc.).

==Let your development web server know where your files are==

Either by editing you web server's config files, or using a symbolic link. Make sure your webserver can see your new working set of files at a sensible URL, so you can test the code you are working on.

==Quick tour of some cool features, and remaining configuration changes==

I find the default workbench setup is pretty good. Here is a quick guide to some of the bits.

===Navigator===

To the left is the '''Navigator'''. This is a tree view of all your files. If you double-click on a file, it opens in the editor in the middle. Try opening '''course/lib.php''' now. You will notice that it comes up nicely syntax-hightlighted.

===Error highlighting===

In the middle of the file, just type any old text, for example "I like Eclipse". Obviously, this is not valid PHP syntax, and Eclipse will notice this, and put a red underline under it. Also, by the scrollbar is a ruler with a red mark in it to show the error.

You will see some yellow marks lower down the ruler. There are warnings. Click on one, and you will be taken to where that warning is in the file. Hover your mouse over the warning, and you will get a tooltip explaining what the problem might be.

Save the edited file. (Don't worry that it is broken, we'll clean up the mess later.) Notice that a red error marker is added to the file in the navigator, so you can see that there is a problem. Also, error markers are added to the course folder, and the whole project, so you could see there was an error even if the navigator tree was collapsed.

You will probably find lots of warnings that the config.php file can't be found. In the navigator, find the file '''config-dist.php'''. Do '''Copy''' then '''Paste''' and choose to call the new file '''config.php'''. Edit this new config.php as normal. You should fine that most of the include file warnings have gone now.

Notice also that there is another marker on each file icon. A little yellow cylinder on most files, but a white-on-brown star on the one you have edited. This is telling you the CVS status of each file. The brown stars are changes you have made but not checked in yet.

===Outline===

Over to the right is the Outline view. This shows a list of functions and classes defined in this file. By default, they are listed in the same order as in the file, but if you click on the '''az''' toolbar button, they are sorted into alphabetical order.

Click on the function name '''add_course_module''' in the Outline. You will see that the editor scrolls to the definition of that function.

===Code navigation===

In that function, hover the mouse pointer over the function name '''insert_record'''. After a while, the documentation for that function will appear in a big tooltip.

Hold down CTRL, move the mouse pointer over the function name '''insert_record''', then click. Eclipse should load '''dmllib.php''', and scroll you to where this function is defined.

In the main Eclipse toolbar, there are forward and back arrows like in a web browser. Click back now to get back to '''course/lib.php'''.

===Open resource===

From the '''Navigate''' menu, choose '''Open Resource...'''. In the dialog that pops up, start typing a filename for instance type '''moodlel'''. In the box in the middle of the dialog, you will see it list all the files in the project whose names start that way. At the bottom is a box which lists the different folders that contain a file with that name. This can be a very quick way of opening files with fairly unique names like moodlelib.php, without having to click through the levels of the navigator tree. Of course, it is not so useful for an index.php file! Click OK now to open moodlelib.php. (It would actually work if you just did CTRL + Shift + R, moodlel, Enter.)

===Multi-file search===

Scroll down moodlelib a little bit, and double click on the name of the constant '''MOODLE_INTERNAL''' where it is defined, so that the text is selected. Then, from the '''Search''' menu, choose '''Search...'''. Notice that the '''Containing text''' box has already been filled in for you with the text you just selected. Of course you can just type text into this box without selecting it first. Notice that you can do regular expression searches, but leave that turned off for now. In the '''File name patterns''' box type '''*.css, *.html, *.inc, *.js, *.php, *.xml'''. (This is the most useful general setting for working on moodle. Eclipse will remember this setting, so you only have to enter it once.) Click '''Search'''.

The search results will appear in a new view underneath the editor. That view has a toolbar with yellow up and down arrows. Click the down arrow a few times and it will take you to the first few matches in the code, opening the relevant files as necessary.

===Synchronize view===

I think this is my favorite feature. From the '''Window''' menu, select '''Show View -> Other...'''. In the dialog that pops up, select '''Team -> Synchronize''', then click '''OK'''.

This opens the Synchronize view below the editor. The view has a toolbar. Click on the first toolbar button, which pops up the Synchronize wizard.

On the first screen, there will probably only be one option: '''CVS'''. Make sure that is selected, then click '''Next >'''.

Under '''Scope''', choose '''Workspace''', then click '''Finish'''.

Wait while it talks to the CVS server. After a while, you will see that the Synchronize view lists course/lib.php, and something called '''.project.... That is, it is listing just the files you have edited, but not checked in yet.

'''.project''' is something that belongs to Eclipse that we don't care about. So select it and bring up the context menu, and choose '''Add to .cvsignore...'''. In the dialog that pops up, choose the top option, then click '''OK'''. Then you will find the Synchronize view shows you a '''.cvsignore''' file that you aren't interested in, so add that to .cvsignore too!

If you double-click on '''course/lib.php''' here, you will see that it opens the compare editor, which is a nice graphical display of the changes in this file.

If you select a file or files here, then bring up the context menu, you will see the option to '''Commit...''' the changes. (But don't do that now!). This is the easiest way to commit things in Eclipse.

However, our changes were rubbish, so we want to undo them. So open the context menu again, and choose '''Override and Update'''. This checks a clean copy of the file out of CVS, removing our changes.

Note that the easiest way to do an ordinary CVS Update is to select the top-level project-folder in the Navigator view on the left, open the context menu, and choose '''Team -> Update'''.

That's all the really important features. I sure you can learn everything else on your own. An you could always read the built in help!

===Creating a patch===

In the synchronise view, right click on an item (file or folder) and choose '''Create Patch...'''. Or in the navigator, right click on an item and choose '''Team -> Create Patch...'''.

This brings up a two-page wizard. On the first page you can select where you want the patch made. For small patches it can be useful to create them on the clipboard, but normally you will want to save them in a file.

On the second page, you can set some options, but normally you don't need to change the defaults which are '''Unified''' diff format, and Patch root set to '''Workspace'''. Well, sometimes it is helpful to change the second one to '''Project''' but it is not important.

There is a corresponding apply patch wizard that you can use to apply a patch to a project.

===Switching to another branch or version===

Suppose you have been using a check-out of HEAD from CVS, and then as the 1.9 release approaches, the MOODLE_19_STABLE branch is created, and you want to start following that instead.
# Right click on the moodle project in the navigator view, and select '''Team -> Switch to Another Branch or Version ...'''.
# choose the second radio button: '''Select the tag from the following list'''.
# If the branch you want is not in the '''Matching tags''' box, see [[Development:Setting_up_Eclipse#Resetting the branch information|Resetting the branch information]] below.
# Select the branch you want and click '''Finish'''.

==Troubleshooting==

Some tips on how to solve common problems that may crop up.

===Resetting the branch information===

Every now and then, Eclipse may lose information on the branch tags it knows about. Hitting refresh tags may fix it, but if not, try the following:

#Bring up the tag dialogue (example using "Team / Switch to Another Branch or Version").
#Click on Configure tags ... (not Refresh tags).
#Select config-dist.php in the top left box (if this is a Moodle checkout).
#Click Add Checked tags.
#Click OK.
#Then you will have all tags.

===Error loading php files after Ubuntu 7.04 Install===

A java issue with Ubuntu 7.04 may cause an error when you attempt to load php pages. Refer to:
http://www.plog4u.org/index.php/Using_PHPEclipse_:_Installation_:_Installing_PHPEclipse for details about how to fix this in Ubuntu 7.04.

After upgrading from Ubuntu 7.04 to 7.10, I had to go in and re-edit the /etc/eclipse/java_home file in order to get the CVS functions to work and be able to open PHP files. When I tried to do a CVS update I initially received an error about org.eclipse.team.internal.ccvs.ui.wizards.CheckoutWizard). Everything seemed to work again after reapplying the fix for the aforementioned 7.04 java issue.
