Is dynamic SERC StringRegExpReplace possible please?

[ni3dprint 0]

Hi folks, 

Thank you so much in advance for your help!  I've been using AUTOIT for manipulating gcode.  So far I've just worked through the excellent help examples and although I'm sure the resulting code is clumsy it has functioned  

However now I'm trying to improve and advance things and I've stumbled across REGEX.. and I'm a bit stuck.  What I would like to be able to do is to 'move'/'transform' the gcode in a file and re-write it to a new file.  I only need to move it in one direction(X).  At the heart of this I need a script to extract all the X values and then ADD or SUBTRACT an adjustment factor to transform and rewrite the code accordingly.

So far using an example script and an example input -

Func Test2()

Local $iMove = -4
    Local $sInput = '"G1 X45.036 Y6.934 F7800.000 G1 Z0.600 F7800.000 G1 F900 G1 X48.036 Y1.076 E0.58925"'
    Local $sOutput = StringRegExpReplace($sInput, '(?<=[X])\d+.\d+', '\0')
    Display($sInput, $sOutput)
EndFunc   ;==>Test2

This identifies the correct values i.e 45.036 and 48.036 but is there a way to dyamically adjust them before they are replaced, by for example a factor of -4 ($iMove above).  So far I can't seem to do math on the '\0' value i.e '\0'+ -4 ?

Many thanks for your time and expertise!

You could use Execute() to make your calculations, that can be used with strings as well.

Give it a try and let us know

Local $iMove = -4
$old = "G1 X45.036 Y6.934 F7800.000 G1 Z0.600 F7800.000 G1 F900 G1 X48.036 Y1.076 E0.58925"

$new = Execute("'" & StringRegExpReplace($old, "(?<=X)\d+.\d+", "' & Execute('$0+' & $iMove) & '") & "'")
Msgbox(0,"", $old & @crlf & $new)

Thank you both for your help.. Wow it works, although I don't really understand the execute line and all the brackets etc..

I had seen Execute() referred to in some of the scripts but there's almost nothing on it in the Help of Autoit so I'll have to get to know it.

Now I just need to build it into the rest of my setup.   Best wishes to you both

Sorry for the lack of explanations 

You can't use a function (in this case, Execute an operation) directly inside the "replace" part of a SRER
So the concept is to build a new string from the subject string by replacing each match by a string including the function, and then apply Execute on this new string

Local $iMove = -4
$old = "G1 X45.036 Y6.934 F7800.000 G1 Z0.600 F7800.000 G1 F900 G1 X48.036 Y1.076 E0.58925"

$string = "'" & StringRegExpReplace($old, "(?<=X)\d+.\d+", "' & Execute('$0+' & $iMove) & '") & "'"
Msgbox(0,"new string", $string)

$new = Execute($string)
Msgbox(0,"result", $old & @crlf & $new)

Hmm was it clear ?

Perfectly - and a nice piece of lateral thinking to get there. Bravo!
