Module: Parser (JSON Reader) Win32

View CPP File

This module will allow you to parse files more easily, like listed below.
This is very recommended when you want to precache files, enumerate swears and set entity variables such viewmodel.
Linux version will be done ASAP.

configuration.ini file.

PHP Code:


		
			
{
   "encoding" : "UTF8",
   "latitude" : -21.512312,
   "maxplayers" : 128,

   "plugins" : [
      "This1",
      "This2"
   ]
}

parser.sma file.

PHP Code:

#include <parser>

    new parserFile:fileId;
    new gameName[16], configsDir[128], fileName[256];

    get_modname(gameName, charsmax(gameName));
    get_localinfo("amxx_configsdir", configsDir, charsmax(configsDir));
    formatex(fileName, charsmax(fileName), "%s/%s/configuration.ini", gameName, configsDir);

    /** If file does not exist, plugin_init forward will stop here.
      */

Re: Module: Parser (JSON Reader) Win32

Good Job man, I like it!

Re: Module: Parser (JSON Reader) Win32

Don't remember if the same format exactly, but I'm thinking importing in AMXX text parser functionality from SourceMod, as even if we won't apply this on current configuration file, I believe it's useful to have unified way for plugin's configs.

Re: Module: Parser (JSON Reader) Win32

Good job :).

I'm happy to hear this :P.

Re: Module: Parser (JSON Reader) Win32

Pretty good job ;)
Is there any chance that this module can parse json from string array?

I don't understand what you mean. Can you give a proper example?

seriously?

PHP Code:


		
			
<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

?>

Code:

object(stdClass)#1 (5) {     ["a"] => int(1)     ["b"] => int(2)     ["c"] => int(3)     ["d"] => int(4)     ["e"] => int(5) }  array(5) {     ["a"] => int(1)     ["b"] => int(2)     ["c"] => int(3)     ["d"] => int(4)     ["e"] => int(5) }

edit: Would be so much better if you port Exolent's JSON include into a module instead of what you've done, because it's "so" specific, and would have more accesibility

Well, I don't really want to copy someone's code. I only wanted a basic JSON reader. Why should I link some already existing natives to a module? Better to use Exolent's existing code if you want to do more than this module can do.

Anyways, I still don't understand what Ovidius meant. Don't tell me you want to parse {"a":1,"b":2,"c":["x","y","z"]} string since this line can be found into a file.
