Plan how a new approach to gitmoji could be compatible with strict commit message standards

[shrink]

carloscuesta/gitmoji is a fantastic idea that has greatly improved my commit messages but it is somewhat incompatible with strict commit message standards. How can this be improved? This project is intended to explore the options.

Using emojis on commit messages provides an easy way of identifying the purpose or intention of a commit with only looking at the emojis used.

How to Write a Git Commit Message

The contributors to these repositories know that a well-crafted Git commit message is the best way to communicate context about a change to fellow developers (and indeed to their future selves).

[...]

1. Separate subject from body with a blank line
2. Limit the subject line to 50 characters
3. Capitalize the subject line
4. Do not end the subject line with a period
5. Use the imperative mood in the subject line
6. Wrap the body at 72 characters
7. Use the body to explain what and why vs. how

[...]

5. Use the imperative mood in the subject line Imperative mood just means “spoken or written as if giving a command or instruction”. A few examples:

Clean your room Close the door Take out the trash Each of the seven rules you’re reading about right now are written in the imperative (“Wrap the body at 72 characters”, etc.).

The imperative can sound a little rude; that’s why we don’t often use it. But it’s perfect for Git commit subject lines. One reason for this is that Git itself uses the imperative whenever it creates a commit on your behalf.

[...]

A properly formed Git commit subject line should always be able to complete the following sentence: If applied, this commit will your subject line here

Rules

• Should describe a commit in the context of a repository -- for example "development environment" not "Docker" -- because otherwise the emoji is very ambiguous (regardless of what the project is the emojis used for the types of commit should be consistent)
  • A repository may be for a project that is not code (e.g: a document repository)
  • or is a project that provides a tool to use for code (e.g: a github action repository)
  • or is a project with source-code for an app
• A commitmoji must describe a change to an area of the project -- not specifically remove or add
• Avoid contradicting gitmoji
• Avoid using similar emojis -- each should be distinct in what they represent
• Avoid cultural references or language specific meanings
• A commit should describe the impact on the project not the code
• Less is more, it should be easy to remember all
• Adding new emojis requires a demonstration of why it should be added (go through process for all initial emojis? a PR for each?)
  • Different project types
  • Example commits
  • Vote?
• Swapping the emoji should change the entire meaning of the message

• [ ] Review the commits of projects that use gitmoji (e.g: gitmoji itself) and then compare to the proposed commitmojis above, preparing a table showing the difference between gitmoji and commitmoji to give a clearer picture of the impact

[shrink]

Conventional Commits is interesting but I'm not sure it captures the same value, but it does have nice tooling so perhaps there's a way to introduce emojis into that standard in some way as an extension? Semantic versioning is valuable for libraries but not so much projects, do the machine readable benefits of Conventional Commits provide value in projects at the expense of humans? The Angular example is worth digging into because they have a mature project implementing the approach.

• [ ] Review Angular usage of Conventional Commits and decide if that is better than emojis
