markdown-embed-code

Embedding code into markdown from external file. Any language's code blocks are available.

See demo repo if you are interested in testing code within README.

How to use

In markdown, write code block as follows (notice that escape sequence "\" must be eliminated):

　\```python:tests/src/sample.py
 
　\```

  And, you can refer specific lines as
  \```python:tests/src/sample.py [4-5]
  
  \```

Then, this action referes to tests/src/sample.py and modifies markdown as (if something code is written, they are overridden):

from math import sqrt


def sample(x):
    return sqrt(x)

And, specific lines is refered as

def sample(x):
    return sqrt(x)

NOTE: Read file by passed path, where the top directory in your repo is working directory. If the path is wrong, this action is failed.

How to use - workflow example

Override README.md and push by action if readme is changed:

name: Embed code in README

on:
  pull_request:
    branches:
      - main

jobs:
  embed-code:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
          persist-credentials: false # otherwise, the token used is the GITHUB_TOKEN, instead of your personal token
          fetch-depth: 0 # otherwise, you will failed to push refs to dest repo
          ref: refs/heads/${{ github.head_ref }}

      - uses: tokusumi/markdown-embed-code@main
        with:
          markdown: "README.md"
          token: ${{ secrets.GITHUB_TOKEN }}
          message: "synchronizing Readme"
          silent: true
