mdbook-cmdrun

This is a preprocessor for the rust-lang mdbook project. This allows to run arbitrary (shell) commands and include the output of these commands within the markdown file.

Getting started

sh cargo install mdbook-cmdrun

You also have to activate the preprocessor, put this in your book.toml file: toml [preprocessor.cmdrun]

How to

Let's say we have these two files:

Markdown file: file.md ```markdown

Title

```

Python file: script.py ```python def main(): print("## Generated subtitle") print(" This comes from the script.py file") print(" Since I'm at in a scripting language,") print(" I can compute whatever I want")

if name == "main": main()

```

The preprocessor will call seq then python3, and will produce the resulting file:

```markdown

Title

1 2 3 4 5 6 7 8 9 10

Generated subtitle

This comes from the script.py file Since I'm at in a scripting language, I can compute whatever I want

```

Details

When the pattern <!-- cmdrun $1 -->\n is encountered, the command $1 will be run using the shell sh like this: sh -c $1. Also the working directory is the directory where the pattern was found (not root). Any command that takes no input, but a list of command lines arguments and produce output in stdout, stderr is ignored.

Examples

The following is valid:

````markdown

rust <!-- runcmd cat program.rs -->

diff <!-- runcmd diff a.rs b.rs -->

console <!-- runcmd ls -l . --> ````

Some more examples are implemented, and are used as regression tests. You can find them here. At the moment of writing, there are examples using: - Shell - Bash script - Python3 - Rust
