On this page we concentrate on developers. We are open to all levels of developers. LibreOffice is one of the biggest, oldest and most known (as OpenOffice) free software packages. If you are a student or looking for development work, being able to write "I have worked for LibreOffice" is a great plus on your CV.

Developers help to improve the LibreOffice code base. At first, the enormous code base can be intimidating, but documentation is improving and you will receive assistance by the existing developers team. This page will help you get your first patch submitted. To help get an overview:

مرشد خطوة بخطوة للمطورين الجدد

It is easy to be overwhelmed by the size and complexity of LibreOffice. The source is written in many different languages and formats — C, C++, Java, Bash, JavaScript, Python, Perl, SQL, XML — and consists of roughly 102,000 files (excluding all localizations) with 36,000,000 lines of text (7,000,000 lines of source code).

Nobody understands the whole code in detail, but we have many core developers who each know part of the code in detail. This step by step guide shows an easy way going from "wanting to contribute" to successfully have the first patch merged to master.

من أجل أن تُجري التطوير تحتاج نسخى محلية من الشفرة المصدرية. نحتفظ بكل المصدر في غِت git. نَسخ الشفرة المصدرية مشروح في مقالات إرشادات التركيب لكل نظام تشغيل.

وندوز Windows

Windows developers need Cygwin and other utilities installed. The easiest way is to use LibreOffice Development Environment (LODE). Detailed Windows build instructions are also available.

نظام ماك macOS

We suggest to follow the instructions that use LibreOffice Development Environment (LODE). More information and details about Xcode can be read in the article Building LibreOffice on macOS.

لينكس Linux

Linux (most flavors) can be set up using the package installers. We suggest you follow Building on Linux

التهيئة لتقديم الإصلاحات

Once you have successfully compiled LibreOffice you are ready to submit patches. We use gerrit to keep track of patches, so you need to create an account there. Follow this gerrit setup guide

There are basically two ways to submit/work with patches. Those familar with Git review can use that, but we recommend a simpler tool called logerrit.

Be careful when committing changes to submodules like help (and only cloning help) as the logerrit script is not available and you might not have the gerrit hook installed. For setup steps, see Development/Submodules.

جد العلّة الأولى لتصلحها

تهانينا، لقد وصلت الجزء الممتع.

Solving the first bug involves learning new tools and ways, therefore we have identified some easy bugs called Easy_Hacks. We use bugzilla where you need to create a account, to keep track of reported bugs.

Easy hacks are real bugs, but the core developers have added source code pointers and sometimes textual help instead of simply solving them, to make it easier for you to solve the bug. Select a bug from your favorite programming language (see above) that interest you EasyHacks by language and skill, as you see there are plenty to choose from. We recommend you choose one from the category "Skill level: beginner", to allow you to concentrate on all the "how do I ....".

Once you have selected a bug to solve, please do not forget to assign it in bugzilla to yourself, so others can see you are working on it. If you want to work on one of the general bugs (like converting foo to xyz), then please do not assign it to you, since many can work on that in parallel. The EasyHacks are monitored so if there are no progress after a time we will unassign it.

حلّ عِلّة

Some practical advice, based on experience, which we recommend that you follow is:

Never make changes to your copy of master - create a branch instead.
Keep a separate branch for each bug, and do not delete the branch until the bug-fix is merged.
follow the Code Style (such as variable naming schemes, etc.).
If you create new files, please use our License Header.
Please avoid larger reformatting of the code for the time being (except for the tasks listed below) - we're pondering auto/magic ways to do that mid- to long-term.

Update master before starting on a new bug (and run make check to confirm it compiles cleanly before you make any changes).
Do not submit patches that depend on each other, unless being told to do so. Doing so will make your patch incapable of being merged.
If your patch is not ready to be merged, assign -2 to it, that way reviewers know it is Work In Progress.
Patience is a key, reviewing takes time and we are all volunteers, so expect a couple of days to pass.

إنسياب عمل مقترح

1. حدّث المستودع الرئيسي

تأكد بأنّ المستودع الرئيس لديك محدّث ويعمل. إذا المستودع الرئيس لديك قديما جدا، فإنك تقع في مخاطرة أن لا تكون قادرا على دمج إصلاحاتك.

As a rule of thumb, use the commands below if:

your master is more than a week old.
your new bug-fix depends on work that just got merged.

./g pull -r
make
make check

!! make must be 3.8.1 or higher.

Please use the -r switch, which is far more effective than simply pulling. Master is frequently broken, but normally only for a short time (committers normally react fast if they make a wrong commit).

When make completes you know you have a working master, so if make breaks while compiling your patch it is due to a problem somewhere in your code. make check runs all test cases and ensures you have a working version of LibreOffice. Running plain make before make check does not cost you build time and in the case of test failures, it ensures you have a build that runs.

2. اعمل في مستودع فرعي

You might be asked later to make changes to your patch, and if you have created and worked in a separate branch that will be very easy. Please use a new branch (from origin/master) for every bug you work on, once the patch has been merged you can delete the branch.

git checkout -b test1 origin/master

Replace test1 with your preferred name.

3. حلّ العلّة

Identify the problem, correct the code, generate and test a version. Remember to supply a unit-test whenever possible to verify that the problem is solved.

There are a number of handy tools to help you

OpenGrok - use it to search and browse the code base
Convert java unit-test to python
cgit commit log
gerrit overview for LibreOffice

Do remember to do git commit -a regularly. This gives you the possibility to easily abandon part of your development, should it turn out to be a wrong path.

4. قدّم الإصلاح

It is recommended that your commit messages look like:

   tdf#12345 <short developer description of change, not just the bug title>
   <empty line>
   <description of what the patch does, the more words the better others understand it later>

if there is a bugreport related to the commit, it's mandatory to start the first line with a bug reference like tdf#12345 (see details below)
use the rest of the first line as a concise summary of your changes. The maximum length for this line is 72 characters.
use present tense. tell what the change does. be terse. avoid "decorations" like dashes and brackets that waste space.
if you want to provide more text than what fits the 1st line, it's mandatory to leave the 2nd line empty
starting from the 3rd line explain what the patch does and why, and if it not obvious also how. These lines should have 80 characters length at most; split into several lines, if your comment is longer. Here you can also describe how the code used to work incorrectly before the change.

If your patch fixes a bug that is already filed in Bugzilla, then you can take advantage of automatic bug-notifications that are triggered by commit-messages: When the first line of the commit message includes a reference to a bug in the form tdf#12345, then a corresponding comment will automatically be added to the bugreport, when the change is pushed to the repository. See the announcement-thread on mail-archive.com or on fdo-listarchive for more details.

Verify that your changes don't break automated testing:

make check

Now you can submit the patch to gerrit (see Prepare to submit patches):

./logerrit submit master

مراجعة الإصلاح الذي تقدمه

In the case of easy hacks, add the person who provided the code pointers as a reviewer for your patch. You will receive an email whenever there is a change in your patch.

In general 3 things can happen in the review:

The committer reviewed and tested the patch successfully, then merged it (congratulations)
The committer had some comments, which you need to look at
Sometimes the patch breaks some other functionality and is marked as “Cannot merge”

In the latter two cases, you need to update your patch.

For more on the patch review process, see Development/gerrit/PatchReview.

تحديث إصلاح

Checkout your branch,

git checkout test1

make the needed changes and test them. It is polite to comment the lines of code you do not want to change or where you do not agree with the committer, this is done directly in gerrit.

Once you are ready to commit again it is important you use --amend

git commit --amend -a

Important do not use the -m parameter as it will wipe out the gerrit patch id. Let git open an editor, allowing you to edit the commit message (or leave it unchanged). When editing be careful not to remove/modify the last line with the patch id.

This will ensure you update the patch, instead of generating a new one (with a new Change-Id:).

Upload the new patch set to gerrit

./logerrit submit master

خارطة طريق للتطوير الشخصي

A developer needs to have specific skills/experience in order to be able to work on LibreOffice Code. This is the path suggested for anyone who wants to get involved in LibreOffice development:

Understand intermediate level C++: Most of the LibreOffice code is in C++, so one should be fluent with C++ in order to be able to work with the code.
Understand git and gerrit: git is the version control software that is used in LibreOffice. One should understand git and gerrit in order to be able to contribute
Be able to build LibreOffice: To be able to change the code, one should be able to build LibreOffice from the sources.
Do at least 10 bug triages: Developers should understand Bugzilla and the workflow associated with bugs and features. This is essential in order to be able to proceed.
Do at least 5 EasyHacks with difficulty beginner (C++): The first step towards being able to understand and change the code.
Do at least 5 EasyHacks with difficulty medium (C++): After doing some easier tasks, it is important to be able to do some more serious work.
Do at least 1 EasyHacks with difficulty interesting
Fix at least 5 regressions: Regressions are usually easy to reproduce, and can be fixed in a reasonable amount of time, so they are suitable for the newcomers
Reach certain number of commits (~60)
Do at least 1 CoreHack

كياسة المبتدئين

Experienced contributors will help you find solutions to your problems, but there are expectations and limits. Remote mentoring and troubleshooting has a greater cognitive load compared to being physically present. Showing you are well-prepared makes people more motivated to help you.

إرشادات عامة:

When using the chat, immediately describe your problem and stay in the channel for at least an hour.
For sharing text with multiple lines in the chat, use a paste service such as the one mentioned in the channel topic.
If you have network connection issues, the mailing list works better than the chat.
If you are doing a complex multi-step task, it is a good idea to keep personal notes. These will come in handy when you are asked what you did so far.
After receiving a reply, acknowledge it somehow. If you disappear without a trace, your helpers will feel distressed.

If you are facing an issue with git, patch submission or setting up the development environment, it is best to follow these steps:

Try to search for the how-to or solution yourself. Sometimes your helpers have to search as well.
If your search was successful, make an attempt to follow the instructions.
If you did not find any instructions or got stuck applying them, ask for help.

With these types of issues, helpers are quite happy to try and solve your entire problem for you.

If you are solving an easy hack, it is good to keep these facts and tips in mind:

There is no single document explaining the code base in prose. Educational material is scattered across conference presentation slides, blog posts and wiki pages.
The frequency of code comments is less than ideal (you can help!), so you should be prepared to read code.
Use git grep, an IDE and OpenGrok to find the definitions of the functions and classes you run into.

Investigate the commit history, also for similar topics elsewhere in the code base. OpenGrok's Annotate command can be revealing for this type of detective work.
Run a debugger while using LibreOffice to find out what is going on under the hood.
Browse the readme files.

If you ask someone to say how to implement something, you will probably be faced with silence. Easy hacks are supposed to be a learning experience and mentors do not want to ruin it. A proposed implementation will be commented on in the review system.
