Your Python project is finally stable; it is more or less working, and you see no major refactors ahead.
Now it is time to write your documentation. You can easily generate it from your docstrings...but you never wrote them down, since the code was changing so quickly.
Bored and beaten, you embrace this hours-long journey to start filling in those blanks.
Or, well, you can use zero-docs!
zero-docs is a simple tool that leverages OpenAI's APIs to automatically generate docstrings for your modules, classes and functions, and open a PR with all of the suggested changes.
It comes with a Github Action, so it requires almost no setup time.
Examples
Following there are some examples setups.
Example 1: Generate Documentation for specific folders or files
With this configuration, the zero-docs action will take the folders or files to scan as input from the UI and generate documentation for them.
name: Auto Doc Generation
on:
workflow_dispatch:
inputs:
paths:
type: string
description: "Space separated list of directories and/or files to scan"
code-entities:
description: "List of code entities to generate docstrings for"
required: false
default: "module,class,function"
jobs:
auto_doc_generation:
runs-on: ubuntu-latest
steps:
- name: Generate Docs
uses: gianfrancodemarco/zero-docs@v1
with:
openai-api-key: ${{ secrets.OPENAI_API_KEY }}
paths: ${{ github.event.inputs.paths }}
reviewers: gianfrancodemarco
Example 2: Generate Documentation for modified files in a pull request
name: Auto Doc Generation
on:
push:
branches:
- main
jobs:
fetch_files:
runs-on: ubuntu-latest
outputs:
files: ${{ steps.changed-files.outputs.all_changed_files }}
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 0 # OR "2" -> To retrieve the preceding commit.
- name: Get changed files
id: changed-files
uses: tj-actions/changed-files@v42
with:
since_last_remote_commit: true
- name: List all changed files
env:
ALL_CHANGED_FILES: ${{ steps.changed-files.outputs.all_changed_files }}
run: |
for file in ${ALL_CHANGED_FILES}; do
echo "$file was changed"
done
auto_doc_generation_only_modified_files:
runs-on: ubuntu-latest
needs: fetch_files
steps:
- name: Generate Docs
uses: gianfrancodemarco/zero-docs@v1
with:
openai-api-key: ${{ secrets.OPENAI_API_KEY }}
paths: ${{ needs.fetch_files.outputs.files }}
reviewers: gianfrancodemarco
Customization
There are some parameters that can be customized (and more to come!):
Name | Description | Required | Default Value |
---|---|---|---|
openai-api-key | API key for OpenAI | true | - |
reviewers | A comma or newline-separated list of reviewers (GitHub usernames) to request a review from. (via create-pull-request) | false | - |
paths | Space separated list of directories and/or files to scan | true | . (root) |
code-entities | Comma separated list of code entities to generate docstrings for | false | module,class,function |
prompt | Prompt to use for generating docstrings | false | (in source code) |
Conclusions
zero-docs can be a useful tool to start documenting your code, not having to start from a blank page.
Will you try it?
