[texworks] Scripting: Libraries: FYI - compilation of equivalent PHP functions for Qt/JavaScript

[Paul A Norman]

Ok,

I've worked through a proof of concept and this looks very feasible,
in fact I'm using it in every day work now.

In it I have used a work around in the meanwhile for loading ECMA libraries.

And wrapped a number of properties and functions in an object called $Tw

The php_js functions are in an object called $PhpJs detailed in
phpjs.namespaced.js from their web site (
http://phpjs.org/packages/configure ).  There would be some editing of
phpjs.namespaced.js needed longterm, but it provides very useful
immediate functionality.

Although php_js does not require it for its own use, I am temporarily
relying on php to give me file read access in loading the needed
JavaScript modules as shown here. This gets the first set of modules
and top level functions in, after that all that would be required for
extra JS libraries is       function module_load(module_name) ...

////////// Begin Preamble

/*  Creates $Tw object with properties and helper functions
    and a function in the current scope:  module_load()

    And sets up  $phpjs = new PHP_JS();

    See notes in scripts/mod_general.js    */

   var scriptName = __FILE__ ;
   var scriptRoot = __FILE__.substr(0,__FILE__.lastIndexOf("/")) ;
   var scriptRoot = scriptRoot.substr(0,scriptRoot.lastIndexOf("/")+1) ;
   var loadFile =  "\"" + scriptRoot + 'mod_loadFile.php\" mod_general.js';
// Non-windows OSes won't need the cmd /c
   var JavaScript = TW.app.system('cmd /c php ' +  loadFile);
   eval(JavaScript);  /*  $Tw and $phpjs objects created  */

////////// END Preamble

Here are some example calls (below) in a Tw QtScript and results,
moving from what we'd expect EMCA to do any way, to extras.

If any one wants to look through this please drop me an email or a
note here, and I'll try and put something of the current state of it
up on the web for download. (Not sure how many are doing Scripting at
present.)

Paul
