python - 解析 CS :GO script file in Python

Question

我正在使用 CS:GO 中的一些脚本文件，我必须从该文件中获取一些有用的信息并将这些数据导入到我的 Python 应用程序中。

这里是一个txt数据格式的例子:

https://steamcdn-a.akamaihd.net/apps/730/scripts/items/items_game.83a9ad4690388868ab33c627af730c43d4b0f0d9.txt

这些值采用随机格式 (Color\Pos\String)，但我只需要一个包含所有值的字符串。我需要将这些信息放入字典中，例如:

print(global_dict['items_game']['game_info']['first_valid_class'])
<<2

我现在正在研究解析器，但我遇到了很多问题。该文件格式是否有现成的解决方案？

Answer 1

作为CoryKramer指出，该文件几乎 JSON。

因此，我在下面编写了一个自定义解析器，它通过逐行读取源配置并将正确的 JSON 格式写入输出文件来解析文件。

我什至使用 JSONLint 测试了输出并且文件已成功验证。

Note: This code was written to parse any of the files located in:

%STEAMINSTALL%/SteamApps/common/Counter-Strike Global Offensive/csgo/scripts

要使用下面的脚本，执行:

 $ ConfigParser.py -h

 usage: ConfigParser.py [-h] [-s SRC] dest
 
 positional arguments:
   dest               file where the parsed JSON will be written to
 
 optional arguments:
   -h, --help         show this help message and exit
   -s SRC, --src SRC  source config file

#!/usr/bin/env python3

"""ConfigParser.py: Parses a Valve configuration file.

The configuration file for the CS:GO game items is read line-by-line
and written to an output file. The missing colons and commas are added
to their appropriate places. The output file passed JSLint validation.

附加说明

似乎有一个用 Java 编写的 CS:GO 配置解析器，它使用 Antlr 语法来解析文件。
