Literate programming in JavaScript using [reStructuredText].

[reStructuredText]: http://docutils.sourceforge.net/rst.html

Detailed documentation is provided in the [src] directories and at
[woofwoofinc.github.io/literacy].

[src]: src
[woofwoofinc.github.io/literacy]: https://woofwoofinc.github.io/literacy

Installing
----------
Literacy is distributed using NPM. See the latest details at the
[Literacy NPM registry page].

[Literacy NPM registry page]: https://www.npmjs.com/package/literacy

Add it to an existing project:

npm install --save literacy

Or with [Yarn]:

yarn add literacy

[Yarn]: https://yarnpkg.com

Usage
-----
Use the literacy command to extract the code blocks from a single .js.rst
file and output to a file.

$ literacy examples/blocks.js.rst --out-file blocks.js

The .js.rst or .json.rst files from an entire source directory can be
processed and output to another directory retaining the relative path prefixes.
This doesn’t overwrite any other files or directories in the output. Use
-out-dir to specify an output directory.

$ literacy --out-dir lib src

To also copy the files which are not .js.rst or .json.rst files from the
source directory to the output directory, include the --copy-files option.

$ literacy --copy-files --out-dir lib src

For other command options and usage, use --help.

$ literacy --help

Literate programming in JavaScript using reStructured Text. This command
extracts code blocks from .js.rst and .json.rst reStructured Text files.

Usage: literacy [options]

Options:
-o, --out-file Compile to an output file [string]
-d, --out-dir Compile to an output directory [string]
-D, --copy-files Copy non-js.rst files to output directory [boolean]
-s, --source-maps Generate source maps for output files [boolean]
-q, --quiet Suppress messages [boolean]
-h, --help Show help [boolean]
-v, --version Show version number [boolean]

Projects which incorporate Literacy can combine documentation and source trees
into a single reStructured Text document. See [src] in this project for an
example. There, the index.rst file is the entry point for the documentation
and includes the source .js.rst files from src/js into the document. These
source files are also separately processed by the Literacy command line tool to
make the lib module directory contents for publishing to the NPM registry.

Require Hook
------------
For non-production use cases there is a require hook for including .js.rst
files without specifying the suffix. This can be convenient for developing in
source trees which use the literacy command to compile to .js files since
the transpilation step can be omitted.

Using a require hook in production code is not recommended practice.

To use the hook, require it from the development run harness, e.g. inside a
wrapper Yarn/NPM script.

require('literacy/lib/register');

Then require .js.rst files as if they were .js files. The hook takes care
of intercepting the extension and performing the JavaScript code block
extraction before handing it to the Node module compiler.

Webpack Loader
--------------
A Webpack loader is provided for integrating Literacy with Webpack to support
.js.rst processing. See the example project included at
example/webpack-literacy.

See the [loader] directories or the [NPM Webpack loader] documentation for
details.

[loader]: loader
[NPM Webpack loader]: https://www.npmjs.com/package/literacy-loader

Developing
----------
The project build stack uses [Node.js] and the [Yarn] package manager. Install
these on your system if they are not already available.

[Node.js]: https://nodejs.org
[Yarn]: https://yarnpkg.com

A [rkt] container build script is included in the project repository and
provides an installation which can be used to build the project also. See the
description on building and running the container in the Development Tools
Container section of the documentation for more information.

[rkt]: https://coreos.com/rkt

For macOS, [RktMachine] provides a CoreOS VM which supports developing using
the rkt container system.

[RktMachine]: https://github.com/woofwoofinc/rktmachine

Start by installing [Literacy] and the other project dependencies using
Yarn.

[Literacy]: https://github.com/woofwoofinc/literacy

$ yarn

Then build the project:

$ yarn build
