Contributing to TiddlyWiki5

Here we focus on contributions via GitHub Pull Requests but there are many other ways that anyone can help the TiddlyWiki project, such as reporting bugs or helping to improve our documentation.

Rules for Pull Requests

PRs must meet these minimum requirements before they can be considered for merging:

The material in the PR must be free of licensing restrictions. Which means that either:
- The author must hold the copyright in all of the material themselves
- The material must be licensed under a license compatible with TiddlyWiki's BSD license
The author must sign the Contributors License Agreement (see below)
Each PR should only make a single feature change
The title of the PR should be 50 characters or less
The title of the PR should be capitalised, and should not end with a period
The title of the PR should be written in the imperative mood. See below
Adequate explanation in the body of the PR for the motivation and implementation of the change. Focus on the why and what, rather than the how
PRs must be self-contained. Although they can link to material elsewhere, everything needed to understand the intention of the PR should be included
Documentation as appropriate for end-users or developers
Observe the coding style
Read the developers documentation
Please open a consultation issue prior to investing time in making a large PR

Imperative Mood for PR Titles

The "imperative mood" means written as if giving a command or instruction. See this post for more details, but the gist is that the title of the PR should make sense when used to complete the sentence "If applied, this commit will...". So for example, these are good PR titles:

If applied, this commit will update the contributing guidelines
If applied, this commit will change css-escape-polyfill to a $tw.utils method
If applied, this commit will make it easier to subclass the wikitext parser with a custom rule set

These a poorly worded PR titles:

If applied, this commit will edit text widgets should use default text for missing fields
If applied, this commit will signing the CLA
If applied, this commit will don't crash if options.event is missing

PR titles may also include a short prefix to indicate the subsystem to which they apply. For example:

Menu plugin: Include menu text in aerial rotator

Commenting on Pull Requests

One of the principles of open source is that many pairs of eyes on the code can improve quality. So, we welcome comments and critiques of pending PRs. Conventional Comments has some techniques to help make comments as constructive and actionable as possible. Notably, they recommend prefixing a comment with a label to clarify the intention:

praise	Praises highlight something positive. Try to leave at least one of these comments per review. Do not leave false praise (which can actually be damaging). Do look for something to sincerely praise
nitpick	Nitpicks are small, trivial, but necessary changes. Distinguishing nitpick comments significantly helps direct the reader's attention to comments requiring more involvement
suggestion	Suggestions are specific requests to improve the subject under review. It is assumed that we all want to do what's best, so these comments are never dismissed as “mere suggestions”, but are taken seriously
issue	Issues represent user-facing problems. If possible, it's great to follow this kind of comment with a suggestion
question	Questions are appropriate if you have a potential concern but are not quite sure if it's relevant or not. Asking the author for clarification or investigation can lead to a quick resolution
thought	Thoughts represent an idea that popped up from reviewing. These comments are non-blocking by nature, but they are extremely valuable and can lead to more focused initiatives and mentoring opportunities
chore	Chores are simple tasks that must be done before the subject can be “officially” accepted. Usually, these comments reference some common process. Try to leave a link to the process description so that the reader knows how to resolve the chore

Contributor License Agreement

Like other OpenSource projects, TiddlyWiki5 needs a signed contributor license agreement from individual contributors. This is a legal agreement that allows contributors to assert that they own the copyright of their contribution, and that they agree to license it to the UnaMesa Association (the legal entity that owns TiddlyWiki on behalf of the community).

For individuals use: licenses/CLA-individual
For entities use: licenses/CLA-entity
