Also, Studio uses LDraw. While Studio isn't typically the first choice amongst the regulars here, Studio discussions are welcome.
I can share you my very dirty PHP code (I am just an system-engineer, no professional developer
) - you may use it as a base to give an idea for your tools.The php file expects the ldraw folder beneath ldraw/ directory
PHP Code:
<?php
//error_reporting(E_ALL);

return array_intersect_key($input, array_flip(preg_grep($pattern, array_keys($input), $flags)));
}
function getSubPartAssemblies($part) {
global $zip;
if(is_file(getcwd().'/ldraw/parts/'.$part.'.dat')) {
$ldrawPath = getcwd().'/ldraw/parts/';
$ldrawPath2 = 'CustomParts/parts/';
}
else {
$ldrawPath = getcwd().'/ldraw/p/';
$ldrawPath2 = 'CustomParts/p/';
}
$zip->addFile($ldrawPath.$part.'.dat', $ldrawPath2.$part.'.dat');
$tmpDatContentArray = file($ldrawPath.$part.'.dat');
foreach($tmpDatContentArray as $line) {
$line = str_replace("\n","",$line);
preg_match_all('/.*[\s](.*\.dat)/', $line, $subAssemblyArray, PREG_SET_ORDER, 0);
if (count($subAssemblyArray) > 0) {
foreach($subAssemblyArray as $subAssemblyLine) {
$subPart = str_replace("\\","/",$subAssemblyLine[1]);
$subPart = str_replace(".dat","",$subPart);
if ($subPart != $part) {
getSubPartAssemblies($subPart);
}
}
}
}
}
function searchPart($part) {
preg_match("/^([\d]{1,}).*?$/",$part,$strippedPartArray, PREG_OFFSET_CAPTURE);
$strippedPart = $strippedPartArray[1][0];
$partsListContent = file_get_contents(getcwd().'/ldraw/parts.lst');

foreach($partsListArray as $tmpPart) {
$partsArray[$tmpPart[1]] = $tmpPart[2];

$findings = preg_grep_keys("/^".$strippedPart.".*/", $partsArray);
return $findings;
