presciidoc (WIP)

Preprocessing AsciiDoc for other tools.

The goal of this program is to partially parse an AsciiDoc file, remove certain non-paragraph elements, and present the document as a syntax tree. Other tools can later analyze or further process the representation.

Warning: This tool is a work in progress and an experiment. It cannot parse the vast majority of AsciiDoc syntax.

Installation

You can install presciidoc on various operating systems using several package managers.

Fedora and CentOS Stream

Enable the Copr repository:
```
# dnf copr enable mareksu/presciidoc
```
Install presciidoc:
```
# dnf install presciidoc
```
The Copr repository distributes packages only for supported releases of Fedora. If you have enabled the repository but the package fails to install, check if your Fedora is still supported.

From source on any platform

Install the Rust toolchain: see https://rustup.rs/.

Install presciidoc:

$ cargo install --git https://github.com/msuchane/presciidoc.git

Usage

presciidoc reads a single AsciiDoc file, either from the specified file path or from the standard input (stdin) if you provide no file.

By default, it performs no actions on the document and prints it back to the terminal (stdout). For example:

$ presciidoc proc_configuring-thing.adoc

// The document starts here.
[id="configuring-thing"]
= Configuring thing

////
Enter a module introduction here.

You can use the --no-comments (-c) option to remove all line comments and comment blocks. presciidoc replaces them with blank lines so that all line numbers still match the original file:
```
$ presciidoc --no-comments proc_configuring-thing.adoc


[id="configuring-thing"]
= Configuring thing




An introduction...
```

To remove the comments completely, rather than replacing them, add the --remove-lines (-r) option:

$ presciidoc --no-comments --remove-lines proc_configuring-thing.adoc

[id="configuring-thing"]
= Configuring thing

To calculate how many lines in the file are comments or literals, use the --fraction (-f) option. This calculates the percentage of the lines that would otherwise get removed:
```
$ presciidoc --no-comments --fraction proc_configuring-thing.adoc

27.8%
```

To save the changes, you can overwrite the original file or create a new file by redirecting the output:

$ presciidoc -c -r proc_configuring-thing.adoc > modified.adoc

[id="configuring-thing"]
= Configuring thing
