`rhai-doc` - Generates HTML Documentation from Rhai Script Files
==============================================================
[](https://github.com/license/rhaiscript/rhai-doc)
[](https://crates.io/crates/rhai-doc/)
[](https://crates.io/crates/rhai-doc/)
`rhai-doc` is a tool for auto-generating documentation for [Rhai] scripts.
It supports writing [MarkDown] documentation in [doc-comments] of [Rhai] scripts and creating
general-purpose documentation pages.
See an example [here](https://rhai.rs/rhai-doc).
CLI Interface
-------------
```text
USAGE:
rhai-doc.exe [OPTIONS] [SUBCOMMAND]
OPTIONS:
-a, --all Generate documentation for all functions, including private ones
-c, --config Set the configuration file [default: rhai.toml]
-d, --dir Set the Rhai scripts (*.rhai) directory [default: .]
-D, --dest Set the destination for the documentation output [default: dist]
-h, --help Print help information
-p, --pages Set the directory where MarkDown (*.md) pages files are located [default:
pages]
-v, --verbose Use multiple to set the level of verbosity: 1 = silent, 2 (default) =
full, 3 = debug
-V, --version Print version information
SUBCOMMANDS:
help Print this message or the help of the given subcommand(s)
new Generates a new configuration file
```
Installation
------------
### Install from `crates.io`
```sh
cargo install rhai-doc
```
### Install from source
```sh
cargo install --path .
```
Configuration File
------------------
To get started, you need a configuration file.
It is usually named `rhai.toml`, or you can specify one via the `--config` option.
To generate a skeleton `rhai.toml`, use the `new` command:
```sh
rhai-doc new
```
### Example
```toml
version = "1.0" # version of this TOML file
name = "My Rhai Project" # project name
color = [246, 119, 2] # theme color
root = "/docs/" # root URL for generated site
index = "home.md" # this file becomes 'index.html`
icon = "logo.svg" # project icon
stylesheet = "my_stylesheet.css" # custom stylesheet
code_theme = "atom-one-light" # 'highlight.js' theme
code_lang = "ts" # default language for code blocks
extension = "rhai" # script extension
google_analytics = "G-ABCDEF1234" # Google Analytics ID
[[links]] # external link for 'Blog'
name = "Blog"
link = "https://example.com/blog"
[[links]] # external link for 'Tools'
name = "Tools"
link = "https://example.com/tools"
```
### Configuration options
- `version`: Version of this TOML file; `1.0` is the current version.
- `name`: The name of the project, if any. It's the title that shows up on the documentation pages.
- `color`: RGB values of the theme color for the generated docs, if any.
- `root`: The root URL generated as part of the documentation, if any.
- `index`: The main [MarkDown] file, if any, that will become `index.html`.
- `icon`: The location of a custom icon file, if any.
- `stylesheet`: The location of a custom stylesheet, if any.
- `code_theme`: The [`highlight.js`](https://highlightjs.org/) theme for syntax highlighting in code blocks (default `default`).
- `code_lang`: Default language for code blocks (default `ts`).
- `extension`: The extension of the script files `rhai-doc` will look for (default `.rhai`).
- `google_analytics`: Google Analytics ID, if any.
- `[[links]]`: External links, if any, to other sites of relevance.
- `name`: Title of external link.
- `link`: URL of external link.
Doc-Comments
------------
[Rhai] supports [doc-comments] in [MarkDown] format on script-defined
[functions](https://rhai.rs/book/language/functions.html).
```rust
/// This function calculates a **secret number**!
///
/// Formula provided from this [link](https://secret_formula.com/calc_secret_number).
///
/// # Scale Factor
/// Uses a scale factor obtained by calling [`get_contribution_factor`].
///
/// # Parameters
/// `seed` - random seed to start the calculation
///
/// # Returns
/// The secret number!
///
/// # Exceptions
/// Throws when the seed is not positive.
///
/// # Example
/// ```
/// let secret = calc_secret_number(42);
/// ```
fn calc_secret_number(seed) {
if seed <= 0 {
throw "the seed must be positive!";
}
let factor = get_contribution_factor(seed);
// Some very complex code skipped ...
// ...
}
/// This function is private and will not be included
/// unless the `-a` flag is used.
private fn get_multiply_factor() {
42
}
/// This function calculates a scale factor for use
/// in the [`calc_secret_number`] function.
fn get_contribution_factor(x) {
x * get_multiply_factor()
}
```
Syntax Highlighting
-------------------
[`highlight.js`](https://highlightjs.org/) is used for syntax highlighting in code blocks.
The default language for code blocks is `ts` (i.e. TypeScript). This default is chosen because Rhai
syntax mostly resembles JavaScript/TypeScript, and highlighting works properly for strings interpolation.
Inter-Script Links
------------------
Functions documentation can cross-link to each other within the same script file.
A link in the format ``[`my_func`]`` is automatically expanded to link to the documentation of
the target function (in this case `my_func`).
MarkDown Pages
--------------
By default, `rhai-doc` will generate documentation pages from [MarkDown] documents within a
`pages` sub-directory under the scripts directory.
Alternatively, you can specify another location via the `--pages` option.
Features
--------
- [x] Generate documentation from [MarkDown] [doc-comments] in [Rhai] script files.
- [x] Create general-purpose documentation pages.
- [ ] Text search.
- [ ] Linter for undocumented functions, parameters, etc.
