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.
sh
cargo install mdbook-cmdrun
You also have to activate the preprocessor, put this in your book.toml
file:
toml
[preprocessor.cmdrun]
Let's say we have these two files:
Markdown file: file.md ```markdown
```
Python file: script.py ```python def main(): print("## Generated subtitle") print(" This comes from the script.py file") print(" Since I'm 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
1 2 3 4 5 6 7 8 9 10
This comes from the script.py file Since I'm in a scripting language, I can compute whatever I want
```
When the pattern <!-- cmdrun $1 -->\n
or <!-- cmdrun $1 -->
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).
The command invoked must take no inputs (stdin is not used), but a list of command lines arguments and must produce output in stdout, stderr is ignored.
As of July 2023, mdbook-cmdrun runs on Windows platforms using the cmd
shell!
The following is valid:
````markdown
rust
<!-- cmdrun cat program.rs -->
diff
<!-- cmdrun diff a.rs b.rs -->
console
<!-- cmdrun ls -l . -->
markdown
Item | Price | # In stock
---|---|---
Juicy Apples | <!-- cmdrun node price.mjs apples --> | *<!-- cmdrun node quantity.mjs apples -->*
Bananas | *<!-- cmdrun node price.mjs bananas -->* | <!-- cmdrun node quantity.mjs bananas -->
Which gets rendered as:
markdown
Item | Price | # In stock
---|---|---
Juicy Apples | 1.99 | *7*
Bananas | *1.89* | 5234
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 - Batch script - Python3 - Node - Rust
I would like to thank @exsjabe for his valuable help with integrating Windows support and inline cmdrun calls.
