GitHub is the world's largest code repository and home to countless open source projects, including many that we actively participate in.
These ideas are suggestions that we think would make good Google Summer of Code projects. They are only meant to be a starting point. Check out our proposal template, and feel free to open an issue to ask questions or discuss other ideas.
Summary: Make the Atom parser faster and better at handling large files and long lines. This includes identifying bottlenecks, developing benchmarks, and possibly re-writing parts of the existing code base in C++ if needed.
Expected Outcome: Improved speed opening files and the 2MB file limit can be increased or removed.
Skills: CoffeeScript, JavaScript, C, C++
Relevant issues: atom/atom#979 and atom/atom#1667
Mentors: @kevinsawicki
Summary: Investigate and implement ways to better support non-US keyboard layouts in the Atom text editor. This would greatly improve the editing experience for anyone using a non-US keyboard layout. This will include engaging with the community to identify the root problem and working through multiple solutions from patching Chromium to crowd-sourcing custom keybinding layouts.
Expected Outcome: Using Atom with a non-US keyboard layout will be a better experience.
Skills: CoffeeScript, JavaScript
Relevant issues: atom/atom-keymap#35 and atom/atom-keymap#37
Mentors: @kevinsawicki
Summary: Solve editing and rendering problems in Atom for files containing Chinese, Japanese, Korean, and Devanagari characters. This will greatly improve the editing experience in Atom.
Expected Outcome: People writing in any language can use Atom as their text editor.
Skills: CoffeeScript, JavaScript
Relevant issues: atom/atom#1783, atom/atom#3821, atom/atom#4007, and atom/atom#4595

Summary: Currently the Linux packages of Atom are built on GitHub's own machines, however in the ideal Linux world we should use services like PPA or OBS to build packages for each Linux distribution. This requires us to provide source tarballs that can be built without the internet. The source tarballs need to be generated for Atom, Atom Shell and libchromiumcontent, and scripts should be provided to build packages from the source tarballs.
Expected Outcome: Packages can be built for each Linux distribution from a source tarball.
Skills: Shell scripting, Python, Chromium, Node.js, grunt, knowledge of C/C++ compilation and linking model, familiarity with Linux packaging on popular distributions.
Relevant issues: atom/atom-shell#259 and atom/atom-shell#735

Summary: A workshopper is an interactive tutorial with exercises in the command line, created by the community around the nodeschool project, that helps developers of all skill sets to get started and/or familiar with a software package, and allows them to learn the most basic and advanced concepts of a piece of technology, in a self paced and guided manner. The aim of this project is to create a workshopper for atom-shell, that has lessons for dealing with basic concepts like installation, testing and bundling, as well as advanced topics like using the ipc module for message passing between browser and client scripts, or adding an app to the task tray.
Expected Outcome: A Command Line Application deployed as a node module on npm, that developers can install globally and run, to learn about Atom-Shell development.
Skills: CoffeeScript, JavaScript, advanced knowledge of Atom Shell Development, familiarity with workshoppers already built by the nodeschool community.
Relevant issues: #22

Summary: We would like to make developing Atom Shell apps easier by providing integrations with popular IDEs and editors, it should able users to create and debug Atom Shell apps without leaving the developing environment. Examples are like Atom package, Visual Studio extension, and WebStorm plugins.
Expected Outcome: A working Atom package or IDE plugin for developing Atom Shell apps.
Skills: JavaScript, experience of developing editor plugins or IDE extensions
Relevant issues: atom/atom-shell#793, atom/atom-shell#804, and atom/atom-shell-starter#53
Mentors: @zcbenz
Summary: The printing feature of Atom Shell only works on Mac and Linux, we would like to implement it on Windows by porting the printing code of Chromium, and also add more printing options.
Expected Outcome: The printing works on Windows, and probably with some new printing related features.
Skills: C++, Win32 APIs
Relevant issues: atom/atom-shell#1157, atom/atom-shell#865, and atom/atom-shell#805

Implement a secure native module loader for Node.js based on Google NaCl's toolchain and validator. As a first step, make it possible for native module authors to explicitly target an NaCl sandboxed container in npm modules. In this mode, authors would be forced to communicate with the main Node process through NaCl's built-in messaging system. As a stretch goal, enable sandboxing of native modules directly in the Node process without modifications by their authors. The requiring Node process should be able to white-list system call APIs, and the V8 extension API should function correctly while restricting memory access that would compromise security.
Expected outcome: A viable mechanism for loading native code in Node applications while maintaining security.
Skills: C++, Assembly, Theoretical understanding of NaCl, V8, and Node.js internals
Relevant issues: atom/atom#1763

Hub is a command-line tool that wraps git to provide an enhanced workflow for repos that are hosted on GitHub. For example, you can checkout, merge, and open new pull requests right from the terminal. For many of its operations hub uses the GitHub API.
Summary: When using git on the command line, shell completions are useful to save keystrokes when expanding long branch names, git remote names, and flags for various git commands. Since hub wraps git, it tries to expand git completion support with its own specific arguments and extra commands, but this doesn't work perfectly on some systems. This project would be developing a unified way to define shell completions for bash, zsh, and fish in a manner that could also be used to extend existing completion scripts for git.
Expected Outcome: A generator that could take a simple declarative markup for content of completions that a particular command should have and output working completion scripts for bash, zsh and fish that implement the described logic.
Skills: shell scripting

Summary: Linguist uses a bayesian classifier to detect the language of a file. A generic tokenizer is currently used for all languages to extract significant symbols. We would like to explore tokenizing contents for each language using the grammar bundles that are currently used for syntax highlighting.
Expected Outcome: A proof of concept that increases the accuracy of Linguist's classifier.
Skills: C++, Ruby, language learning
Summary: Linguist currently uses multiple strategies to detect the language of a file, including matching on file name, heuristics, and bayesian classification. Each strategy is relatively independent, making it difficult to aggregate them into a more probable match. We would like to explore an algorithm that combines all strategies into a confidence score.
Expected Outcome: Increased accuracy in language detection and the ability to return "unknown" if the confidence score is not above a threshold.
Skills: Ruby, language learning

Summary: Taps (3rd-party Homebrew package repositories) currently just add new formulae to the list of those available. Instead of symlinking into Library/Formula taps should be searched for formulae and allow prioritisation and overriding of packages in the core repository.
Expected Outcome: Taps can be prioritized.
Skills: Ruby, Unix
Summary: Currently Homebrew formulae cannot be renamed as packages are installed into e.g. Cellar/package/1.2.3. Provide a way of renaming formulae using Git history as a guide and handling existing installed packages.
Expected Outcome: Formulae can be renamed without causing issues for users.
Skills: Ruby, Unix, Git
Summary: Homebrew requires developer tools (Xcode and/or the CLT) to install most software. Even when binary packages are available some developer tools are needed to fix them up after installation and Homebrew will try to compile software even with a missing compiler.
Expected Outcome: Improve the usability and tooling to fix these issues.
Skills: Ruby, Unix
Summary: When installing e.g. mysql from a binary package all runtime dependencies (e.g. openssl) should be included within the Cellar/mysql/1.2.3 folder. This means that a single file should be all that's needed to be downloaded for mysql to have its dependencies and a manual upgrade or uninstall of openssl should not affect the mysql formula. This is inspired by the way .app bundles package all their dependencies.
Expected Outcome: Binary packages will include all of their dependencies.
Skills: Ruby, Unix
