Tips and Tricks / Quick execute any portable(and not only) program(and scripts)

« on: July 07, 2017, 16:53:54 »

Hello there
I'm using a large number of portable programs for a long time(including Multi Commander).
Some of them are console, the others are GUI, but most of them accept arguments.
Sometimes it's very handy to use MC tools for shortcuts/buttons/file type setup, but in most cases this is not enough for me, therefore, I decided to make a tiny tool which finds and executes specified filename(or even the beginning of the filename). First version was written in Batch script, it had worked pretty slow and I've rewritten it to C(the code is below).

This tool (let's call it just "run") supports executing .bat, .cmd, .exe, .vbs and any other extension located in PATHEXT global variable
It tries to find specified file recursively, starting with root to itself folder. This is especially useful with portable devices where all paths should be relative. That's how portable programs approximately organized in my PC:

Code: [Select]

X:\data\exec\!run.exe    <--- Our tool. I called it "!run" because I have another program called "run"
X:\data\exec\script1.vbs <---vbs script
X:\data\exec\script2.bat <---batch script
X:\data\exec\mc\MultiCommander.exe
X:\data\exec\firefox\firefox.exe
X:\data\exec\sysinternals\procmon\procmon.exeAnd so on

To execute any of them with any arguments, I only need to "!run <filename> [args]"
For example:
"!run upx -9 target.exe" - run upx\upx.exe with arguments "-9 target.exe"
or
"!run proc" - run sysinternals\procmon\procmon.exe
or
"!run multi" - run mc\multicommander.exe

Using this tool with MC is very useful because you can easily copy filepaths and pass them as arguments. (Don't forget to wrap path arguments with spaces in quotation marks, otherwise your programs will parse them as different arguments)
Keep in mind that MC command line is limited to visible borders, but I hope this will be changed in future.

Well, let's integrate our tool with Multi Commander:
1. Add new script

Code: [Select]

function GetArgs()
{
  @var $args = "";
  @var $n;
  @var $a;
  for( $n = 1; $n < $argcount; $n = $n + 1 )
  {
       $a = $arg($n);
       $args += ' "' + $a + '"';
  }
  return $args;
}

@var $cmd = GetTagValue("${mcinstallpath}") + "\\..\\!run.exe"; //change this line to your !run.exe path if needed!!!
@var $cmdargs = StrTrimLeft($arg(0), ":") + GetArgs();

if( StrFind($arg(0), ":", 0) == 0 )
  MC.Run CMD="{$cmd}" ARG="{$cmdargs}" ADMIN
else
  MC.Run CMD="{$cmd}" ARG="{$cmdargs}"Note that script also allow you to run our tool with Admin rights by prefixing filename with ':'

2. Make alias for that script. Personally, I use just "r"

3. Use it!
Same examples using MC:
r firef - run X:\data\exec\firefox\firefox.exe
r upx -9 "C:\Program Files\Test\Test.exe" - run X:\data\exec\upx\upx.exe with arguments "-9 "C:\Program Files\Test\Test.exe""
r :procm - run X:\data\exec\sysinternals\procmon\procmon.exe with admin rights

Note that you can use it the same way everywhere - just locate !run.exe in program files for example, and modify path to !run.exe in MC scripts(or make additional script)

I hope it will be helpful for someone   
And sorry for my bad English

Feature Requests and Suggestions / SFX archives support

« on: June 28, 2017, 15:54:19 »

Hello, Mathias
Is it possible to make SFX archives support? 7zfm deals with such files. I guess this requires just to check file for MZ sig and if overlay exists, check it as normal archive

How to get value of "${focusfilepath}"?

In this code it always returns nothing

Code: [Select]

@var $cmdargs = "powershell dir " + GetTagValue("${focusfilepath}") + "-Recurse | Unblock-File";
MC.Run CMD="powershell" arg="{$cmdargs}"

Support and Feedback / Multi tags in aliases

« on: April 15, 2016, 13:26:53 »

Is there a way to use multi tags in aliases(/command line)? My MC located in removable drive which is assigned with random drive letter in different devices. Using scripts for each alias is undesirable:c

Script / Passing arguments to MC.Run

« on: April 13, 2016, 13:03:24 »

Trying to use this script:

Code: [Select]

function GetArgs()
{
  @var $args = "";
  @var $n;
  for( $n = 1; $n < $argcount; $n = $n + 1 )
  {
       $args = $args + " ";
       $args = $args + $arg($n);
  }
  return $args;
}
@var $s = GetTagValue("${mcinstallpath}") + "\\..\\";
$s = $s + $arg(0);
$s = $s + "\\";
$s = $s + $arg(0);
$s = $s + ".exe";
@var $args = GetArgs();
MC.Run CMD="{$s}" ARG="{$args}"The problem is the script trims double quotemarks splitting "a complex argument" into 3 arguments:

Code: [Select]

run test "a complex argument"

argc = 4
C:\mc\..\test\test.exe
a
complex
argument

So I can't send filepath with spaces
how to solve this problem?

Support and Feedback / MC.Run ADMIN

« on: April 08, 2016, 18:10:35 »

Property ADMIN don't work for me even for "MC.Run CMD="Notepad.exe" ADMIN" from example
Process rights depends on MC's: if MC elevated it ALWAYS run app with ADMIN otherwise without admin rights regardless ADMIN option
Windows 10 x64
What should I do?
