An ini format parser and serializer for node.
|
||
|
|
|
||
|
|
Sections are treated as nested objects. Items before the first
|
||
|
|
heading are saved on the object directly.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Consider an ini-file `config.ini` that looks like this:
|
||
|
|
```ini
|
||
|
|
; this comment is being ignored
|
||
|
|
scope = global
|
||
|
|
|
||
|
|
[database]
|
||
|
|
user = dbuser
|
||
|
|
password = dbpassword
|
||
|
|
database = use_this_database
|
||
|
|
|
||
|
|
[paths.default]
|
||
|
|
datadir = /var/lib/data
|
||
|
|
array[] = first value
|
||
|
|
array[] = second value
|
||
|
|
array[] = third value
|
||
|
|
```
|
||
|
|
|
||
|
|
You can read, manipulate and write the ini-file like so:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var fs = require('fs')
|
||
|
|
, ini = require('ini')
|
||
|
|
|
||
|
|
var config = ini.parse(fs.readFileSync('./config.ini', 'utf-8'))
|
||
|
|
|
||
|
|
config.scope = 'local'
|
||
|
|
config.database.database = 'use_another_database'
|
||
|
|
config.paths.default.tmpdir = '/tmp'
|
||
|
|
delete config.paths.default.datadir
|
||
|
|
config.paths.default.array.push('fourth value')
|
||
|
|
|
||
|
|
fs.writeFileSync('./config_modified.ini', ini.stringify(config, { section: 'section' }))
|
||
|
|
```
|
||
|
|
|
||
|
|
This will result in a file called `config_modified.ini` being written
|
||
|
|
to the filesystem with the following content:
|
||
|
|
|
||
|
|
```ini
|
||
|
|
[section]
|
||
|
|
scope=local
|
||
|
|
[section.database]
|
||
|
|
user=dbuser
|
||
|
|
password=dbpassword
|
||
|
|
database=use_another_database
|
||
|
|
[section.paths.default]
|
||
|
|
tmpdir=/tmp
|
||
|
|
array[]=first value
|
||
|
|
array[]=second value
|
||
|
|
array[]=third value
|
||
|
|
array[]=fourth value
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
### decode(inistring)
|
||
|
|
|
||
|
|
Decode the ini-style formatted `inistring` into a nested object.
|
||
|
|
|
||
|
|
### parse(inistring)
|
||
|
|
|
||
|
|
Alias for `decode(inistring)`
|
||
|
|
|
||
|
|
### encode(object, [options])
|
||
|
|
|
||
|
|
Encode the object `object` into an ini-style formatted string. If the
|
||
|
|
optional parameter `section` is given, then all top-level properties
|
||
|
|
of the object are put into this section and the `section`-string is
|
||
|
|
prepended to all sub-sections, see the usage example above.
|
||
|
|
|
||
|
|
The `options` object may contain the following:
|
||
|
|
|
||
|
|
* `section` A string which will be the first `section` in the encoded
|
||
|
|
ini data. Defaults to none.
|
||
|
|
* `whitespace` Boolean to specify whether to put whitespace around the
|
||
|
|
`=` character. By default, whitespace is omitted, to be friendly to
|
||
|
|
some persnickety old parsers that don't tolerate it well. But some
|
||
|
|
find that it's more human-readable and pretty with the whitespace.
|
||
|
|
|
||
|
|
For backwards compatibility reasons, if a `string` options is passed
|
||
|
|
in, then it is assumed to be the `section` value.
|
||
|
|
|
||
|
|
### stringify(object, [options])
|
||
|
|
|
||
|
|
Alias for `encode(object, [options])`
|
||
|
|
|
||
|
|
### safe(val)
|
||
|
|
|
||
|
|
Escapes the string `val` such that it is safe to be used as a key or
|
||
|
|
value in an ini-file. Basically escapes quotes. For example
|
||
|
|
|
||
|
|
```js
|
||
|
|
ini.safe('"unsafe string"')
|
||
|
|
```
|
||
|
|
|
||
|
|
would result in
|
||
|
|
|
||
|
|
"\"unsafe string\""
|
||
|
|
|
||
|
|
### unsafe(val)
|
||
|
|
|
||
|
|
Unescapes the string `val`
