You probably already have an idea +of something you'd like to work on. If not, here are just a few ways you +can help: + + * Pick a bug, fix it, and send in a merge request on GitLab. + * Choose a feature you want to see developed, and make it. + * If you speak a language in addition to English, work on your + language's i18n file in the po/ directory. + * Find a new bug and report it. + * Help answer questions for new Inkscapers on IRC, forum, or the + mailing lists. + * Write an article advocating Inkscape. + * Author a HOWTO describing a trick or technique you've figured out. + + +GIT Access +---------- + +Inkscape is currently developed on git, with the code hosted on GitLab. + + * https://gitlab.com/inkscape/inkscape + +We give write access out to people with proven interest in helping develop +the codebase. Proving your interest is straightforward: Make two +contributions and request access. + +Compiling the development version +--------------------------------- + +See http://wiki.inkscape.org/wiki/index.php/CompilingInkscape for general +remarks about compiling, including how to find some of the needed packages for +your distribution, and suggestions for developers. + + +Patch Decisions +--------------- + +Our motto for changes to the codebase is "Patch first, ask questions +later". When someone has an idea, rather than endlessly debating it, we +encourage folks to go ahead and code something up (even prototypish). +This is then incorporated into the development branch of the code for +folks to try out, poke and prod, and tinker with. We figure, the best +way to see if an idea fits is to try it on for size. + + +Coding Style +------------ + +Please refer to the Coding Style Guidelines +(https://inkscape.org/en/develop/coding-style/) if you have specific questions +on the style to use for code. If reading style guidelines doesn't interest +you, just follow the general style of the surrounding code, so that it is at +least consistent. + + +Documentation +------------- + +Code needs to be documented. Future Inkscape developers will really +appreciate this. New files should have one or two lines describing the +purpose of the code inside the file. + + +Building (In Linux distribution) +-------------------------------- + +This is the best set of instructions for setting up your build directory... + +You should install ninja and ccache for the fastest build: + +```bash +sudo apt-get install ninja-build ccache +``` + +Next we prepare a build directory with a symlink to Inkscape's share folder, add a profile dir and set the bin folder (optional): + +```bash +ln -s $PWD/share ./share/inkscape +mkdir -p build/conf +cd build +export INKSCAPE_PROFILE_DIR=$PWD/conf +PATH=$PWD/bin/:$PATH +``` + +Now we invoke cmake, letting it know to use our new build directory prefix, ccache and the Ninja compiler: + +```bash +cmake -DCMAKE_INSTALL_PREFIX:PATH=$PWD/../ -DCMAKE_C_COMPILER_LAUNCHER=ccache -DCMAKE_CXX_COMPILER_LAUNCHER=ccache -DCMAKE_BUILD_TYPE=Debug -G Ninja .. +``` + +Invoke ninja to build the code. You may also use plain gcc's `make` if you didn't specific `-G` in the command above: +```bash +ninja +``` + +Now we can run `inkscape` that we have built, with the latest resources and code: + +```bash +./bin/inkscape +``` + +To build in Non-Linux Platforms check out `INSTALL.md` (Links to Inkscape Wiki pages are given right below "Basic Installation") + +Profiling +--------- + +To run with profiling, add `-DWITH_PROFILING=ON` to the above cmake script. Compiling and running will be slower and the gmon file will appear only after Inkscape quits. + +See: https://wiki.inkscape.org/wiki/index.php/Profiling + +Testing +------- + +Before landing a patch, the unit tests should pass. + +See: http://wiki.inkscape.org/wiki/index.php/CMake#Using_CMake_to_run_tests + +General Guidelines for developers +---------------------------------- + +* If you are new, fork the inkscape project (https://gitlab.com/inkscape/inkscape) and create a new branch for each bug/feature you want to work on. Try to Set the CI time to a high value like 2 hour (Go to your fork > Settings > General Pipelines > Timeout) +* Merge requests (MR) are encouraged for the smallest of contributions. This helps other developers review the code you've written and check for the mistakes that may have slipped by you. +* Before working on anything big, be sure to discuss your idea with us ([IRC](irc://irc.freenode.org/#inkscape) or [RocketChat](https://chat.inkscape.org/)). Someone else might already have plans you can build upon and we will try to guide you ! +* Adopt the coding style (indentation, bracket placement, reference/pointer placement, variable naming etc. - developer's common sense required!) of existing source so that your changes and code doesn't stand out/feel foreign. +* Carefully explain your ideas and the changes you've made along with their importance in the MR. Feel free to use pictures ! +* Check the "Allow commits from members who can merge to this target branch" option while submitting the MR. +* Write informative commit messages ([check this](https://chris.beams.io/posts/git-commit/)). Use full url of bug instead of mentioning just the number in messages and discussions. +* Try to keep your MR current instead of creating a new one. Rebase your MR sometimes. +* Inkscape has contributors/developers from across the globe. Some may be unavailable at times but be patient and we will try our best to help you. We are glad to have you! |
