parse the source safe history output and run the diff command - batch-file

Question

I am fairly new to writing batch scripts. I am trying to write a script file to achieve the following task.
I have a source safe command below to get the list of files changed between two dates
ss.exe history $/myproject -Vd04/01/2012~01/01/2012 -R
The output of the above command is as follows
Building list for $/myproject.......................................................
....................................................................................
...................................
***** AllPages.master *****
Version 67
User: user1 Date: 1/12/12 Time: 1:08p
Checked in $/myproject/websites/website1
Comment:
***** AdminTSSetup.aspx.vb *****
Version 10
User: user2 Date: 1/12/12 Time: 1:09 p
Checked in $/myproject/websites/website1
Comment:
With the output above, I want to read the file name (allpages.master, AdminTsSetup.aspx.vb) and version of each file from the output and run the following command
SS diff -DS <filename from output> -V<version from output - 1>~<version from output>
Basically, I was trying to compare the previous version with the current version for each file in the output.
Can some one please help?

Answer 1

This should give you what you asked for. But it seems like the diff command you specified is missing a reference to the project.
This solution should work even if the file name contains spaces, !, ;, or any special characters like & or ^.
#echo off
setlocal disableDelayedExpansion
for /f "delims=*" %%A in ('ss.exe history $/myproject -Vd04/01/2012~01/01/2012 -R ^| findstr /b "***** Version"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
if "!ln:~0,1!"==" " (
for /f "eol=: delims=" %%F in ("!ln:~1!") do (
endlocal
set "file=%%~nxF"
)
) else (
for /f "tokens=2 delims= " %%V in ("!ln!") do (
set /a "version1=%%V, version0=version1-1"
ss.exe dif -DS "!file!" -V!version0!~!version1!
endlocal
)
)
)
Here is a version that adds the project information from the "Checked in" line
#echo off
setlocal disableDelayedExpansion
for /f "delims=*" %%A in ('ss.exe history $/myproject -Vd04/01/2012~01/01/2012 -R ^| findstr /b "***** Version Checked"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
if "!ln:~0,1!"==" " (
for /f "eol=: delims=" %%F in ("!ln:~1!") do (
endlocal
set "file=%%~nxF"
)
) else if "!ln:~0,1!"=="V" (
for /f "tokens=2 delims= " %%V in ("!ln!") do (
endlocal
set /a "version1=%%V, version0=version1-1"
)
) else (
for /f "tokens=2* delims= " %%B in ("!ln!") do (
endlocal
set "proj=%%C"
setlocal enableDelayedExpansion
ss.exe dif -DS "!proj!/!file!" -V!version0!~!version1!
endlocal
)
)
)

Answer 2

Basically you need a for loop and a little state:
#echo off
setlocal enabledelayedexpansion
for /f "tokens=1,2 delims= " %%i in ('ss.exe history $/myproject -Vd04/01/2012~01/01/2012 -R') do (
if "%%i"=="*****" (
rem a file name
set "FileName=%%j"
) else (
if "%%i"=="Version" (
set Version=%%j
set /a LastVersion=Version - 1
ss diff -DS "!FileName!" -V!LastVersion!~!Version!
set FileName=&set Version=&setLastVersion=
)
)
)
Should kinda work, I guess.
