充分利用通过svnlook的Windows批处理日志消息 [英] Getting log message from svnlook via windows batch

问题描述

我尝试prepare我的svn库一个post-commit钩子。因此，我需要从最后的日志信息提交，我用命令获得svnlook的日志-r％REV％REPOS％％。灌装片段与适当的PARAMS我得到以下multline日志消息：

 此
是
我的
交易。
 

这工作得很好至今。现在我把这个.bat文件：

  @ECHO OFFREM只是用于测试目的...
SET REPOS = C：\\回购
SET REV = 40FOR / F %% i的（'svnlook的日志-r％REV％REPOS％％）做SET VAR = %%我ECHO％VAR％
 

当我执行该脚本只有最后一行交易。是呼应。 for循环是的，我想一个片段，它会读取svnlook的输出到％VAR％。

我的做法是在一个变量，这是我传递给其他的EXE文件作为参数来获取日志消息。但它不会工作。我不知道如何正确使用循环。

日志消息应该给予另一EXE文件作为参数。<​​/ P>

我修改剧本以下（@thx PA）。

  @ECHO OFF
SETLOCAL enabledelayedexpansionSET REPOS = C：\\回购
SET REV = 40SET MSG =
FOR / F %% i的（'svnlook的日志-r％REV％REPOS％％）做SET VAR =！VAR！ ％％一世
ECHO！VAR！
 

输出是现在这是我的事务。但断行都走了，但我需要做进一步处理。

解决方案

你还想换行符，你的串联线路时，可以将它们添加。

  @ECHO OFF
SETLOCAL enabledelayedexpansion
设置LF = ^
REM **两个空行是必要的SET REPOS = C：\\用户\\ CH.ROSESOFT \\下载\\ T3 \\回购
SET REV = 40SET MSG =
FOR / F %% i的（'svnlook的日志-r％REV％REPOS％％'）做（
    SETVAR =！VAR！LF！%%我
    SETPAR =！PAR！^^！LF !! LF！%%我
）
ECHO！VAR！
myProgram.exe！相提并论！
 

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.

解决方案

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!
