Commit

Syntax

Valid commit messages have the structure:

[product]\[type]([scope]): #[issue-number] [title] // This is the commit title
               // This blank line separates the commit title from the commit body
[body]         // This is the commit body. It CAN have multiple lines

• [variable] are required variables that must be replaced in a final commit message ([] symbols must be removed)
• // Comment are comments that must be removed in a final commit message

Rules

The following rules must be met for a commit message to be valid, the product rule only required for the integrates repository:

1. [type] variable has to be one of the following:

   rever  // Revert to a previous commit in history
   feat   // New feature
   perf   // Improves performance
   fix    // Bug fix
   refac  // Neither fixes a bug or adds a feature
   test   // Adding missing tests or correcting existing tests
   style  // Do not affect the meaning of the code (formatting, etc)
   sol    // Hacking solution only for writepus and training repo

2. [scope] variable has to be one of the following:

   front  // Front-End change
   back   // Back-End change
   infra  // Infrastructure change
   conf   // Configuration files change
   build  // Build system, CI, compilers, etc (scons, webpack...)
   job    // asynchronous or schedule tasks (backups, maintenance...)
   cross  // Mix of two or more scopes
   doc    // Documentation only changes
   vbd    // Vulnerable by design hacking solution only for writeups repo
   code   // Programming challenge solution only for training repo
   hack   // ctf-hacking challenge solution only for training repo

3. [product] variable has to be:

   integrates // Changes that affect both integrates and forces

4. A Commit title must exist.

5. A Commit title must not contain the ':' character.

6. Commit title must have 60 characters or less.

7. Commit title must be lower case.

8. Commit title must not finish with a dot '.'.

9. Commit title must reference an issue.

10. Commit title must be meaningful. Avoid using things like feat(build)[integrates]: #5 feature.

11. If commit title has sol type, it must reference issue #0.

12. A blank line between commit title and commit body must exist.

13. A commit body must exist.

14. Lines in commit body must have 72 characters or less.

15. If commit title has fix type, the body must reference the commit sha of the bug in the format - fixing: $COMMIT_SHA.

Possible combinations

Below is a table explaining all the possible combinations between types and scopes for a commit message (Types are columns, scopes are rows):

	rever	feat	perf	fix	refac	test	style
front	Revert front-end to a previous version	Add new feature to front-end	Improve perf in front-end	Fix something in front-end	Change something in front-end	Add tests for front-end	Change front-end code style
back	Revert back-end to a previous version	Add new feature to back-end	Improve perf in back-end	Fix something in back-end	Change something in back-end	Add tests for back-end	Change back-end code style
infra	Revert infra to a previous version	Add new feature to infra	Improve perf in infra	Fix something in infra	Change something in infra	Add tests for infra	Change infra code style
conf	Revert config files to previous a version	Add new feature to config files	NA	Fix something in config files	Change something in config files	NA	Change config files code style
build	Revert building tools to previous a version	Add new feature to building tools or add a new building tool	Improve building perf	Fix something in building tools	Change something in building tools	Add tests for building tools	Change building tools code style
job	Revert jobs to previous a version	Add new feature to jobs or add a new job	Improve jobs perf	Fix something in jobs	Change something in jobs	Add tests for jobs	Change jobs code style
cross	Revert several scopes to previous a version	Add new feature for several scopes	Improve perf in several system parts	Fix something in several system parts	Change something in several system parts	Add tests for several system parts	Change code style in several system parts
doc	Revert doc to a previous version	Add new doc	NA	Fix something in doc	Change something in doc	NA	Change doc style

Where:

• perf is performance.
• infra is infrastructure.
• config is configuration.
• doc is documentation.
• NA is not applicable.

Recommendations

• Try to itemize your commit body:

  - Add feature X in file Y
  - Run script Z
  - Remove file A with B purpose

Example

Here is an example of a compliant commit message:

integrates\feat(build): #13 add type_check

- Add type_check function
- Remove unnecessary print_output function
