Text Parser

[cbk1994]

Someone needed this, so I made it.

This reads text, and uses a "Smart Parser" to go through it and change variables to the value. To signal a variable, put @VARNAME@ in the code. GS1 will not work, and things such as servername will also not. I have tested this with clientr, client, player, server, and serverr. They all work. Here are the commands:

PHP Code:

parseFile( "path/to/file.txt" );
The way I used this was in a server message, I used Parser.parseFile( "data/servermessage.txt" ); This will return an array of the file, simply parsed.

parseText( string/array )
You can give a string, or an array as a paramater. Will only parse the first param though, so put things in an array if you want. If you give it an array, it will return an array. If you give it a string, it will return a string. 


Code for wNPC Parser:

PHP Code:

// Made by Chris Zakuto
function doInit()
{
  // Must be a single character, sorry!
  this.sepText = "@"; // The symbol that seperates variables from text.
}
function onCreated()
{
  doInit();
}

public function parseFile( filepath )
{
  if ( temp.fileContents != NULL )
  {
    temp.fileContents = NULL;
  }
  
  if ( temp.a != NULL )
  {
    temp.a.clear();
  }
  temp.fileContents.loadLines( filepath );
  
  for ( temp.n: temp.fileContents )
  {
    temp.a.add( temp.n );
  }
  
  temp.fileText = parseText( temp.a );
  
  return temp.fileText;
}
// "Smart Parser" returns the same type (array or string)
public function parseText( text )
{
  if ( temp.returnText != NULL )
  {
    if ( temp.returnText.size() > 0 )
    {
      temp.returnText.clear();
    }
    
    temp.returnText = NULL;
  }
  if ( text.size() > 0 )
  {
    for ( temp.a: text )
    {
      temp.returnText.add( parseLine( temp.a ) );
    }
  }
  else
  {
    temp.returnText = parseLine( text );
  }
  
  return temp.returnText;
}

// Actually parse the text.
function parseLine( realText )
{
    if ( temp.chars != NULL )
  {
    temp.chars.clear();
  }
  
  for ( temp.i = 0; temp.i < realText.length(); temp.i ++ )
  {
    temp.chars.add( realText.substring( temp.i, 1 ) );
  }
  
  if ( temp.isVar != false )
  {
    temp.isVar = false;
  }
  for ( temp.n: temp.chars )
  {
    if ( temp.isVar == false ) // Variable has not been detected.
    {
      if ( temp.n == this.sepText ) // Start of a variable.
      {
        temp.isVar = true;
      }
      else
      {
        temp.parsedText = temp.parsedText @ temp.n;
      }
    }
    else
    {
      if ( temp.n != this.sepText )
      {
        temp.varAdd = temp.varAdd @ temp.n;
      }
      else
      {
        temp.isVar = false;
        temp.finalVar = makevar( temp.varAdd );
        temp.parsedText = temp.parsedText @ temp.finalVar;
        temp.varAdd = "";
      }
    }
  }
  
  // temp.parsedText is final output.
  return temp.parsedText;
} 


To use this, input text like this:

PHP Code:

Welcome to @serverr.servername@, @player.account@:@player.nick@ of @player.guild@! You currently have @clientr.money@ money, and you have been online for @player.onlinetime@ seconds! If we had a player.ip variable, yours would be @player.ip@. 


Have fun, please leave comments.

I've always wondered what the hell parsing even is.

this is pretty neat, good job

ego ++; thanks.

An alternative is that you can use a substring to find the length of 'sepText' meaning that it can be more than one character, this is important because if there is are @'s in the file then they can easily be screwed up by this parser. I would make the 'sepText' something like '###obj.var###'

Well, you can always find something fancy. ` is hardly used, for example.

` (squiggly key)

Or you can script it so its compatible with tags.

<variable>player.nick</variable>

True, maybe I'll make an update for that.

Wouldn't it be better to use format(); ?

What does format() have to do with this? We're talking about concatination in text files.

[Deadly_Killer]

Hmm. It may be better to do something like:

PHP Code:

while (temp.something.pos("@") > 0)
{
  // stuff here.
} 


Either way, cool

Didn't think of it like that thats a good idea. Could save alot of time too

I don't tend to trust while() in GS2. Never has worked right for me.

Most likely because you forgot to use the sleep function so you dont crash yourself. I've never liked using while() either

You guys must not realize that this:
for (i = 0; i < j; i++) {
func();
}
is simply:
i = 0;
while (i < j) {
func();
i++;
}

Also, checking every single letters seems to be A LOT of work. Much more effcient if you just found the first position of "@" and just moved like such. Hell, you could even tokenize("@") the whole thing and just do a for loop through the tokens (changing the mode of "variable" or "text" on every other token).
