That is: 14 | 15 | * Node v8.x: V8 v5.8.x (will be updated to v6.x soon) 16 | * Node v6.x: V8 v5.1.281.x 17 | * Node v4.x: V8 v4.5.103.x 18 | 19 | We will drop support when the corresponding Node.js LTS version is dropped. 20 | 21 | For the grammar of these logs, see [grammar.md](doc/grammar.md). 22 | 23 | ## As CLI tool 24 | 25 | ```console 26 | npm install -g v8-gc-log-parser 27 | # output the result as JSON to stdout 28 | v8-gc-log-parse 29 | ``` 30 | 31 | ## API 32 | 33 | ### class `GCLParser` 34 | 35 | ```js 36 | const Parser = require('v8-gc-log-parser');
