%P without backslash

[wolf]

When I call a program using the change button bar feature, I can pass %P as parameter. %P represents the path terminated by a "\". Is there clever solution for removing the backslash?

Currently I have two ideas for a workaround.
1. using ? and do manual editing.
2. writing a proxy program

Correction: In contrast to the (german) docu, totalcommander uses a slash not a backslash.

But my problem remains unsolved ..

Can anybody give me hint how to start kdiff3.
When I use
"%P" "%T"
the slashes are disturbing.

User a shell script and remove the trailing char with the string functions of cmd, before you invoke kdiff3.

Try %P. with the dot after it. The dot means "current dir", and most programs will accept it.

That is the simple solution, I was looking for.

Thank you!!

This thread is a bit old , but I just ran into the same problem.
By combining cmd-substrings and delayed environment variable expansion, I was able to produce the following native (Windows 10) one-liner:

Command:

Code: Select all

cmd /V:ON /K

Parameters:

Code: Select all

"set "ZZZZ=%T" && echo "target=%T" && echo "target_fixed=!ZZZZ:~0,-1!" && echo "source=%P%S""

This demo button produces a cmd.exe window with the following text:

Code: Select all

"target=c:\Temp\2\"
"target_fixed=c:\Temp\2"
"source=c:\Temp\1"

A bit ugly, but it works.

Note: All parameters now support substring fields in the form :~start,length, e.g. %N:~2,5 or %N:~-8,5 . To append a number directly after the length value, use another ~ character, e.g. %N:~2,5~2. Negative vaules are measured from the end of the string. Example: %P:~0,-1 cuts off the backslash from the path.
The Start value -0 is special: %N:~-0,20 copies the first 20 characters of the name without extension, %N:~-0,-20 the first 20 characters of the extension without the name.
