I try to prepare a post-commit hook for my svn repository. Therefore i need the log message from the last commit which I get with the command svnlook log -r %REV% %REPOS%. Filling the snippet with the appropriate params I get the following multline log message:
This
is
my
transaction.
This works well so far. Now I put this in a .bat file:
@ECHO OFF
REM just for testing purpose...
SET REPOS=C:\repo
SET REV=40
FOR /F %%i in ('svnlook log -r %REV% %REPOS%') do SET VAR=%%i
ECHO %VAR%
When I execute the script only the last line transaction. is echoed. The for-loop is a snippet from which I thought, it would read the svnlook output into %var%.
My approach is to get the log message in a variable, which I pass to another exe-file as parameter. But it won't work. I don't know how to properly use the loop.
The log message should given to another exe-file as an parameter.
I modified the script to the following (@thx PA.)
@ECHO OFF
setlocal enabledelayedexpansion
SET REPOS=C:\repo
SET REV=40
SET MSG=
FOR /F %%i in ('svnlook log -r %REV% %REPOS%') do SET VAR=!VAR! %%i
ECHO !VAR!
The output is now This is my transaction. But the linebreak are gone but I need the for further processing.
As you want also the linebreaks, you can add them when concatenating the lines.
@ECHO OFF
setlocal enabledelayedexpansion
set LF=^
rem ** The two empty lines are NECESSARY
SET REPOS=C:\Users\CH.ROSESOFT\Downloads\t3\repo
SET REV=40
SET MSG=
FOR /F %%i in ('svnlook log -r %REV% %REPOS%') do (
SET "VAR=!VAR!!LF!%%i"
SET "PAR=!PAR!^^!LF!!LF!%%i"
)
ECHO !VAR!
myProgram.exe !par!
