sean0x42/markdown-extract repository overview

Extract sections of a markdown file with a regular expression! Great for changelogs ;)

⁠Usage

Given a document called my-document.md:

# Welcome

This is my amazing markdown document.

## Extract me!

This section should be pulled out.

You can extract the second section with the following command:

$ markdown-extract "Extract me!" my-document.md
## Extract me!

This section should be pulled out.

⁠Installation

If you've got Rust installed on your system, you can simply install markdown-extract with Cargo.

$ cargo install markdown-extract

⁠Docker

A Docker image is also available, and can be installed with the following command:

$ docker pull sean0x42/markdown-extract:v2

You can then run the container with the following command:

$ docker run -it sean0x42/markdown-extract:v2 --help

Note that because markdown-extract accesses the file system, you will need to mount a volume if you want to access a file on the host. e.g.

$ docker run -v $PWD:/opt -it sean0x42/markdown-extract:v2 v2.0.0 /opt/CHANGELOG.md

If you know a better way of achieving this, please let me know!

⁠Use Cases

There aren't many, to be honest.

1. Extract patch notes from a CHANGELOG.md by version.
2. The talented folks at HashiCorp are using markdown-extract to extract API documentation, and inject it into OpenAPI schemas.

If you have another use for this tool, please let me know!
