Hi,

In the split function and getsubstringindex functions that I am writing

I need the fastest way to check if a character is present within a variable

It looks like this

Code: Select all

set _SPLT_CurrentWindow=!%_SPLT_Input_Pointer%:~%_SPLT_Index%,%_SPLT_Actual_Search_Window_len%!
set _SPLT_CurrentWindowResult=!_SPLT_CurrentWindow:%_SPLT_Search%=!
if %_SPLT_CaseSensitivity% !_SPLT_CurrentWindow! NEQ !_SPLT_CurrentWindowResult!

Unfortunately this fails with some special characters
I think this explains why I couldn't find an all purpose pure batch split function in the wild :\

So I made a function to test all poison character substitution in the source or substitution string, to find which substitution don't work and how to create a workaround for all cases.

I identified 5 major ways this failes

without delayed expansion
When you try to replace something WITH a percentsign (works with enableelayedexpansion)
When you try to replace a percentsign with something else (works with enableelayedexpansion)

with delayed expansion
When you try to replace something WITH an exclamation (works with disabledelayedexpansion)
When you try to replace an exclamation with something else (works with disabledelayedexpansion)
and if you try to replace a doublequote with &<>^| then you must escape them (works with disabledelayedexpansion)

Problematic lines (test result and test code below)

Not working without delayed expansion

::replacing with a percentsign

Code: Select all

set "_substvar13=%_testvar:s=%%%"
set "_substvar13=%_testvar:!=%%%"
set "_substvar13=%_testvar:"=%%%"
set "_substvar13=%_testvar:&=%%%"
set "_substvar13=%_testvar:(=%%%"
set "_substvar13=%_testvar:)=%%%"
set "_substvar13=%_testvar:<=%%%"
set "_substvar13=%_testvar:>=%%%"
set "_substvar13=%_testvar:|=%%%"

::replaceing a percentsign

Code: Select all

set "_substvar11=%_testvar:%%=!%"
set "_substvar12=%_testvar:%%="%"
set "_substvar13=%_testvar:%%=%%%"
set "_substvar14=%_testvar:%%=&%"
set "_substvar15=%_testvar:%%=(%"
set "_substvar16=%_testvar:%%=)%"
set "_substvar17=%_testvar:%%=<%"
set "_substvar18=%_testvar:%%=>%"
set "_substvar19=%_testvar:%%=^%"
set "_substvar20=%_testvar:%%=|%"

Not working with delayed expansion

:: replacing with !

Code: Select all

set "_substvar11=!_testvar:s=!!"
set "_substvar11=!_testvar:"=!!"
set "_substvar11=!_testvar:%%=!!"
set "_substvar11=!_testvar:&=!!"
set "_substvar11=!_testvar:(=!!"
set "_substvar11=!_testvar:)=!!"
set "_substvar11=%_testvar:<=!%"
set "_substvar11=%_testvar:>=!%"
set "_substvar11=%_testvar:^=!%"
set "_substvar11=%_testvar:|=!%"

:: replacing a !
set "_substvar11=!_testvar:!=!!"
set "_substvar12=!_testvar:!="!"
set "_substvar13=!_testvar:!=%%!"
set "_substvar14=!_testvar:!=&!"
set "_substvar15=!_testvar:!=(!"
set "_substvar16=!_testvar:!=)!"
set "_substvar17=!_testvar:!=<!"
set "_substvar18=!_testvar:!=>!"
set "_substvar19=!_testvar:!=^!"
set "_substvar20=!_testvar:!=|!"

replacing a doublequote
set "_substvar11=!_testvar:"=!!" <- doesn't work as usual
set "_substvar12=!_testvar:"="!" <- works fine
set "_substvar13=!_testvar:"=%%!" <- works fine
set "_substvar14=!_testvar:"=&!" --> escape with carret set "_substvar14=!_testvar:"=^&!"
set "_substvar15=!_testvar:"=(!" <- works fine
set "_substvar16=!_testvar:"=)!" <- works fine
set "_substvar17=!_testvar:"=<!" --> escape with carret set "_substvar17=!_testvar:"=^<!"
set "_substvar18=!_testvar:"=>!" --> escape with carret set "_substvar18=!_testvar:"=^>!"
set "_substvar19=!_testvar:"=^!" --> escape with carret set "_substvar19=!_testvar:"=^^!"
set "_substvar20=!_testvar:"=|!" --> escape with carret set "_substvar20=!_testvar:"=^|!"

So coming back to my script

Code: Select all

set _SPLT_CurrentWindow=!%_SPLT_Input_Pointer%:~%_SPLT_Index%,%_SPLT_Actual_Search_Window_len%!
set _SPLT_CurrentWindowResult=!_SPLT_CurrentWindow:%_SPLT_Search%=!
if %_SPLT_CaseSensitivity% !_SPLT_CurrentWindow! NEQ !_SPLT_CurrentWindowResult!

In this bit I am in delayedexpansion mode

In all cases I am deleting the characters,

So of all these special cases

Only when _SPLT_Search contains a "!" am I going to get in trouble ?

Also I just noticed I need to put this line in quotes

set "_SPLT_CurrentWindowResult=!_SPLT_CurrentWindow:%_SPLT_Search%=!"

Maybe that's all I need

Split can't work on delimiters containing "!", that would be the only limitation... maybe ?
