I wanted a simple setup in Symfony where the programmer could define their ide in the parameters file. Sounds simple, right? Just add something like ide_url: 'phpstorm' to parameters.yml->parameters and ide: '%ide_url%' to config.yml->framework. And it worked great, however, my problem was much more convoluted.

I am actually running the Symfony server on another machine and am accessing the files via NFS on Windows. So, it would try to open PHPStorm with the incorrect path. Symfony suggests the solution to this is writing your own custom URL handler with %f and %l to fill in the filename and line, and use some weird formatting to do string replaces. So I wrote in 'idea://%%f:%%l&/PROJECT_PATH_ON_SERVER/>DRIVE_LETTER:/PATH_ON_WINDOWS/' (note the double parenthesis for escaping) directly in the config.yml and that worked, kind of. The URL was perfect, but IntelliJ does not seem to register the idea:// protocol handler like PHPStorm theoretically does (according to some online threads) with phpstorm://. So I had to write my own solution.

This answer on stackoverflow has the answer on how to register a protocol handler in Windows. But the problem now was that the first parameter passed to IntelliJ started with the idea:// which broke the command-line file-open. So I ended up writing a script to fix this, which is at the bottom.

OK, so we’re almost there; I just had to paste the string I came up with back into the parameters.yml, right? I wish. While this was now working properly in a Symfony error page, a new problem arose. The Symfony bin/console debug:config framework command was failing with You have requested a non-existent parameter "f:". The darn thing was reading the unescaped string as 'idea://%f:%l&...' and it thought %f:% was supposed to be a variable. Sigh.

So the final part was to double escape the strings with 4 percent signs. 'idea://%%%%f:%%%%l&...'. Except now the URL on the error pages gave me idea://%THE_PATH:%THE_LINE_NUMBER. It was adding an extra parenthesis before both values. This was simple to resolve in the script I wrote, so I was finally able to open scripts directly from the error page. Yay.



So here is the final set of data that has to be added to make this work:
Registry: HKCR/idea/(default) = URL:idea Protocol HKCR/idea/URL Protocol = "" HKCR/idea/shell/open/command = "PATH_TO_PHP" -f "PATH_TO_SCRIPT" "%1" "%2" "%3" "%4" "%5" "%6" "%7" "%8" "%9" parameters.yml: parameters: ide_url: 'idea://%%%%f:%%%%l&/PROJECT_PATH_ON_SERVER/>DRIVE_LETTER:/PATH_ON_WINDOWS/' config.yml: framework: ide: '%ide_url%' PHP_SCRIPT_FILE:
<?php
function DoOutput($S)
{
	//You might want to do something like output the error to a file or do an alert here
	print $S;
}

if(!isset($argv[1]))
	return DoOutput('File not given');
if(!preg_match('~^idea://(?:%25|%)?([a-z]:[/\\\\][^:]+):%?(\d+)/?$~i', $argv[1], $MatchData))
	return DoOutput('Invalid format: '.$argv[1]);

$FilePath=$MatchData[1];
if(!file_exists($FilePath))
	return DoOutput('Cannot find file: '.$FilePath);

$String='"C:\Program Files\JetBrains\IntelliJ IDEA 2018.1.6\bin\idea64.exe" --line '.$MatchData[2].' '.escapeshellarg($FilePath);
DoOutput($String);
shell_exec($String);
?>
