TOML Parser for Node.js
|
|
=======================

If you haven't heard of TOML, well you're just missing out. [Go check it out now.](https://github.com/mojombo/toml) Back? Good.
|
|
|
|
TOML Spec Support
|
|
-----------------
|
|
|
|
toml-node supports version 0.4.0 the TOML spec as specified by [mojombo/toml@v0.4.0](https://github.com/mojombo/toml/blob/master/versions/en/toml-v0.4.0.md)
|
|
|
|
Installation
|
|
------------
|
|
|
|
toml-node is available via npm.
|
|
|
|
npm install toml
|
|
|
|
toml-node also works with browser module bundlers like Browserify and webpack.
|
|
|
|
Usage
|
|
-----
|
|
|
|
### Standalone
|
|
|
|
Say you have some awesome TOML in a variable called `someTomlString`. Maybe it came from the web; maybe it came from a file; wherever it came from, it came asynchronously! Let's turn that sucker into a JavaScript object.
|
|
|
|
```javascript
|
|
var toml = require('toml');
|
|
var data = toml.parse(someTomlString);
|
|
console.dir(data);
|
|
```
|
|
|
|
`toml.parse` throws an exception in the case of a parsing error; such exceptions have a `line` and `column` property on them to help identify the offending text.
|
|
|
|
```javascript
|
|
try {
|
|
toml.parse(someCrazyKnuckleHeadedTrblToml);
|
|
} catch (e) {
|
|
console.error("Parsing error on line " + e.line + ", column " + e.column +
|
|
": " + e.message);
|
|
}
|
|
```
|
|
|
|
### Streaming
|
|
|
|
As of toml-node version 1.0, the streaming interface has been removed. Instead, use a module like [concat-stream](https://npmjs.org/package/concat-stream):
|
|
|
|
```javascript
|
|
var toml = require('toml');
|
|
var concat = require('concat-stream');
|
|
var fs = require('fs');
|
|
|
|
fs.createReadStream('tomlFile.toml', 'utf8').pipe(concat(function(data) {
|
|
var parsed = toml.parse(data);
|
|
}));
|
|
```
|
|

### Requiring with Node.js
|
|
|
|
You can use the [toml-require package](https://github.com/BinaryMuse/toml-require) to `require()` your `.toml` files with Node.js
|
|
|
|
Live Demo
|
|
---------
|
|
|
|
You can experiment with TOML online at http://binarymuse.github.io/toml-node/, which uses the latest version of this library.
|
|
|
|
Building & Testing
|
|
------------------
|
|
|
|
toml-node uses [the PEG.js parser generator](http://pegjs.majda.cz/).
|
|
|
|
npm install
|
|
npm run build
|
|
npm test
|
|
|
|
Any changes to `src/toml.peg` requires a regeneration of the parser with `npm run build`.
|
|
|
|
toml-node is tested on Travis CI and is tested against:
|
|
|
|
* Node 0.10
|
|
* Node 0.12
|
|
* Latest stable io.js
