Text Parsing script?

[CBruce]

I'm very new to scripting, but what I'm hoping to be able to do seems very straightforward...I just have no idea how to start.

We have thousands upon thousands of script files that we use to define particle emitters. These don't follow any logical formatting, but I'd like to rectify that through a script. Here is an example of an unformated particle script:

Code: Select all

End

What I'd like to be able to do is open up one of these particle files, and run a javascript that will go through and read each line and store the values as a variable, then output them into a more formatted version of the file that looks something like this:

So far, I've figured out how to have UltraEdit ask me for a file name, create the new file, paste the template version of the particle script into it (line by line)...but that's it. I'm at a complete loss as to how to read a variable from one file and paste it into the new one.

Here's my progress so far:

// Reads in variables from particle script and outputs into a templated format

// object.

I have it mostly figured out...the part I'm not sure how to address is this part:

Code: Select all

// Get variables from current document
var NewPerFrameSource="NewPerFrame      0.1" //This line is just a placeholder to work on the next two instructions.
var i = NewPerFrameSource.lastIndexOf("   ");
var NewPerFrame = NewPerFrameSource.slice(i + 1);

How can I read the current document and look for a line that contains a certain string (ie, NewPerFrame), then copy that whole line in as a variable that I can then use the lastIndexOf and slice to par down to the final variable/string I need to paste into my new format?

Here is something that might inspire you to further develop your script.

I start from the part where you write "Get variables from current document" and end before "UltraEdit.newFile()";

Code: Select all

// Get variables from current document

// Helper prototype to make a perl regexp available for UE find command:
RegExp.prototype.toUEregexp = function() { return this.toString().replace(/^\/|\/$/g, ""); }; /* remove starting and ending slashes */

// Set up search defaults:
UltraEdit.activeDocument.findReplace.matchCase=false;
UltraEdit.activeDocument.findReplace.matchWord=false;
UltraEdit.activeDocument.findReplace.regExp=true;
UltraEdit.activeDocument.findReplace.searchDown=true;
UltraEdit.activeDocument.findReplace.searchInColumn=false;

// Use Perl regexp engine:
UltraEdit.perlReOn();

// Goto top of document:
UltraEdit.activeDocument.top();

// Perl regexp that will find the lines with variable assignments.
// Lines starting with # is ignored (comments)
// Leading whitespace is ignored
// Two tagged expressions : \1 = Name, \2 = Value
// Not explained any further. To do your own study go to: http://www.regular-expressions.info/
var searchRegexp = /^[ \t]*?([^# \t\r\n]+)[ \t]+(.*)$/;

// Go through the file while finding lines with variables assignments
while (UltraEdit.activeDocument.findReplace.find(searchRegexp.toUEregexp())) {

   // Get selected text
   var line = UltraEdit.activeDocument.selection;

   // Extract variable name and value by re-executing the perl regexp on the text with the exec-method.
   var [ , variableName, variableValue ] = searchRegexp.exec(line);

   // Compose javascript with variable name and value, that test for any undefined variables.
   // Those are ignored while defined variables are reassigned a new value,
   var assignmentStatement = "if (typeof("+variableName+") == \"undefined\") { /* ignore */ } else { "+variableName+ "= \"" +variableValue+ "\" } ";
   
   // Execute "composed" javascript with eval function
   eval(assignmentStatement);
}

//Create a new file, which will become the currently active document

I'm still trying to figure out what you did (zero familiarity with Perl regexp, so that bit looks like magic to me), but it's working perfectly. Thanks a ton.

One more small thing. Is there a way to look at the variableValue for any decimals that don't have a 0 in front of them?

For example, I might be getting this:
InitialVelocity .001 0.0 -.1

And I'd really like to be outputting this:
InitialVelocity 0.001 0.0 -0.1

I'm thinking the solution may be more trouble than it's worth, but it can't hurt to ask.
Again, thanks for your help with this.

[jorrasdk]

Well add this function to the script:

Code: Select all

function editNumerics(variableValue) {
   // Reduce spaces to a single space between numbers
   variableValue = variableValue.replace(/[ ]{2,}/g," ");

   // Split into an array
   var numbers = variableValue.split(" ");

   // Examine every number
   for (var i=0;i<numbers.length;i++) {
      // Use a regexp to find numbers starting with . or -. and put a 0 in front
      numbers[i] = numbers[i].replace(/^(\-)?(\.\d+)$/,"$10$2");
   }

   // Join array again and return it
   return numbers.join(" ");
}

Then change the line that "composes" the assignmentStatement to:

Code: Select all

var assignmentStatement = "if (typeof("+variableName+") == \"undefined\") { /* ignore */ } else { "+variableName+ "= editNumerics(\"" +variableValue+ "\") } ";

[CBruce]

Wanted to thank you for all your help. I'll be honest, a lot of what you've given me is way over my head, but it's working exactly as I hoped it would. I hope it was easier for you to do than it looks to me

[CBruce]

Back again. Right now the script is creating a new document and pasting the formated code into it. Is there a way to just get all of the variables from the current document, select all, delete, and then paste the formatted script back into the original file?

What I'm currently using is this:

Code: Select all

UltraEdit.activeDocument.findReplace.replaceAll=true
UltraEdit.activeDocument.top();
UltraEdit.activeDocument.findReplace.replace(".*","");
UltraEdit.activeDocument.top();
UltraEdit.activeDocument.findReplace.replace("\r","");
UltraEdit.activeDocument.top();
UltraEdit.activeDocument.findReplace.replace("\n","");

Which seems to work, but also seems very hacky.

[jorrasdk]

Just use:

Code: Select all

UltraEdit.activeDocument.selectAll();
UltraEdit.activeDocument.deleteText();
