Contributing Guide

Working on your first Pull Request? You can learn how from this free series How to Contribute to an Open Source Project on GitHub

How to contribute summary

Often it can be helpful to discuss a PR first in an Issue to avoid later problems or re-design when it is in review.

  • Fork the project and submit a Pull Request (PR)
    • Explain what the PR fixes or improves
    • Screenshots for bonus points
  • Use sensible commit messages
    • Short descriptive title in the first line, one empty line, and then multiple lines with an explanation (why and how).
    • If your PR fixes a separate issue number, include it in the commit message like Fixes: #123 (on a separate line).
  • Use a sensible number of commit messages as well
    • e.g. Your PR should not have 100s of commits
    • If you fix a previous commit of the PR it might be worth considering to squash them

How to add yourself to the contributors (give yourself attribution)

Don't forget to give yourself credit! Make sure you add yourself to the contributors list that will eventually propagate to NerdFonts.com Usually the person pulling your PR will make sure you did not forget this step.

Either:

  • Invoke the @all-contributors bot by commenting on your Pull Request or Issue.
  • (not advised) Shallow clone repo and execute all-contributors add <YOUR_GITHUB_HANDLE> <CONTRIBUTION_TYPE>

Common types for this project include: code, doc, translation, review. For full list of contribution types see: https://allcontributors.org/docs/en/emoji-key

Steps for updating an existing font

1. Update original (unpatched) version

  • Copy and replace the existing unpatched version of the font and any readme and/or license files in the src/unpatched-fonts/XYZ directory
    • e.g. Updating XYZ Font, update files in directory src/unpatched-fonts/XYZ/{PUT FONT FILES HERE}
    • Make sure to update the correct subfolders for each font style (e.g. src/unpatched-fonts/XYZ/Bold/{BOLD FONT FILES HERE}), but only if the subfolder structure is already existing
    • Update version information in the readme.md file(s) and bin/scripts/lib/fonts.json
    • Add all the modifications into a git commit

2. Execute basic testing

  • Do a basic test with the new font to ensure it patches correctly and generates a new font file, e.g.
    • fontforge --script ./font-patcher src/unpatched-fonts/XYZ/XYZ.ttf --complete --debug 2
    • Make sure to then delete this new font file if it is in the repository

3. Run build scripts

This is not needed and you should never commit any patched files directly to the repo. The Github workflow will do that at appropriate times.

  • When fairly satisfied the font patches correctly, run the following:
    • Patch all of the variations/options, e.g.
      • ./gotta-patch-em-all-font-patcher\!.sh /XYZ

Steps for adding a new font or removing an existing font

1. Verify license

  • Check the license even allows the font to be modified and shared

2. Add original (unpatched) version

  • Add the unpatched version of the font and any license files to the src/unpatched-fonts/ directory inside a new directory
    • e.g. Adding XYZ Font, create directory src/unpatched-fonts/XYZ/{PUT FONT FILES HERE}
    • Do not make subfolders for each font style
    • Add a README.md file to src/unpatched-fonts/XYZ that follows the style of the existing fonts
    • If the font has only Oblique instead of Italic, set that (and other specials) in the config.cfg file
    • Update information in the /readme.md file(s)
    • Insert font into bin/scripts/lib/fonts.json; use repoRelease=false
    • Add all the modifications into a git commit

3. Execute basic testing

  • Do a basic test with the new font to ensure it patches correctly and generates a new font file, e.g.
    • fontforge --script ./font-patcher src/unpatched-fonts/XYZ/XYZ.ttf --complete --debug 2
    • Make sure to then delete this new font file if it is in the repository (all patched fonts should be generated in the patched-fonts directory)

4. Run build scripts

  • When fairly satisfied the font patches correctly, run the following:
    • Patch all of the variations/options, e.g.
      • NERDFONTS='--debug 2 --makegroups 1' ./gotta-patch-em-all-font-patcher\!.sh /XYZ
    • If there are name length problems you might want to use --makegroups 2 or increasing (3, 4, ...), until all fonts of the set come out without error.
    • To increase testing speed add --dry to the NERDFONTS variable above.
    • Add the needed makegroups level (if it is not 1) to the config.cfg file and amend your commit.

5. Release

  • As we do not release directly to the repository anymore the new font will only be seen on a real release.
  • For that the font image preview will also be needed (generate-font-image-previews.sh).
  • What is automated via Github workflows and what not might change over time, so nothing is specified here.

Steps to add a new icon to the core set

Codepoints in the code set are a scarce resource, so in general it is unlikely that an icon will be added.

  • To add a icon one just needs to throw the svg into the correct directory and add a line to icons.tsv.
  • The workflow than automagically updates the i_seti.sh and the original-source.otf (workflow PackSVGs).

Things to keep in mind

  • Smaller Pull Requests are likely to be merged more quickly than bigger changes
  • This project is using a KISS Workflow
    • Pull Requests and bugfixes are directly merged into the default branch after sanity testing
    • The default branch is basically consider the main developer branch
      • We no longer wait to get changes into the default branch when there is a release/milestone/version!
    • The release branches and version tags are considered stable and frozen
  • This project is using Semantic Versioning 2.0.0
    • If a bugfix or PR is not trivial it will likely end up in the next MINOR version
    • If a bugfix or PR is trivial or critical it will likely end up in the next PATCH version
  • Useful Pull Requests will get merged in eventually

Commit messages

  • Squashing to 1 commit is not required at this time
  • Use sensible commit messages (when in doubt: git log)
  • Short descriptive title in the first line, one empty line, and then multiple lines with an explanation (e.g. why and how).
  • Use a sensible number of commits
  • If your PR fixes a specific issue number, include it in the commit message: Fixes: #123 as this activates the autolink and autoclose mechanism.

Code standards

Shell Scripts

Python

  • Use 4 spaces for indentation
  • Consider PEP8 and other (@todo)
