immutable-kv

A js module for Valve KV format. Support #base feature.

Install

npm install immutable-kv

Import

import KV from 'immutable-kv';

KV Parser

parse

Use parse function to convert string to KV instance:

const kv = KV.parse(`
"root" {
	"aaa"	"bbb"
	"ccc"	"ddd"
}
`);

kv.key; // 'root'
kv.isList; // true
kv.get(['aaa']); // 'bbb'
kv.getKV(['ccc']).key; // 'ccc'
kv.getKV(['ccc']).value; // 'ddd'
kv.getKV(['ccc']).isList; // false

update

Call setValue to get new KV instance. The same as setKey and setComment:

const kv = KV.parse('"aaa" "bbb"');
const newKv = kv.setValue('ccc');

kv.value; // 'bbb'
newKv.value; // 'ccc'

KV File

load

Call load to load kv data from file:

const kv = KV.load('/tmp/kv.txt');

Or you can set customize encoding:

const kv = KV.load('/tmp/kv.txt', 'utf8');

#base support

const kvFileInfo = KV.baseLoad('/tmp/kv.txt');
kvFileInfo.kv; // KV instance
kvFileInfo.path; // Absolute path
kvFileInfo.baseList; // List contains base refer KVFileInfo
kvFileInfo.baseList[0].kv; // Base KV instance
kvFileInfo.baseList[0].relativePath; // Path related to parent KV file

update kv

const newKvFileInfo = kvFileInfo.setKV(newKV);

update base kv

setBase(origin: index | KV | KVFileInfo, target: KV | KVFileInfo)

const newKvFileInfo = kvFileInfo.setBase(origin, target);
