Batch-File
防止擴展:在批處理文件中for循環
嘗試建構用於查看 TFS 變更集的 cmdline 工具。目前我有這個:
rem I know there's redundancy here, but don't care for now set /A curr=%1 set /A prev=%curr% set /A prev-=1 for /f "tokens=2" %g in ('tf changeset /noprompt %curr%') do tf diff /noprompt /format:unified /version:C%prev%~C%curr% %g
這給出了以下結果:
g:\>tfdiffchangeset.bat 2458 currunified was unexpected at this time.
我什至不確定為什麼 : 變成了“curr”,但是如果我刪除 /format,我會在 /version 中發生同樣的事情。
其次,如果我只是用空格替換 :’s 假設我稍後會處理它,我會收到這個錯誤
g:\>tfdiffchangeset.bat 2458 The following usage of the path operator in batch-parameter substitution is invalid: %~C%curr% %g For valid formats type CALL /? or FOR /? The syntax of the command is incorrect.
是時候編寫 tfdiffchangeset.pl 了嗎?
最終版本:
@ECHO off set /A CURR=%1 rem Note - just using one changeset less doesn't necessarily work, because branches also use the same changeset numbers set /A PREV=%CURR%-1 echo diffs for %CURR% tf changeset /noprompt %CURR% for /f "tokens=2" %%g in ('tf changeset /noprompt %CURR%') do tf diff /noprompt /format:unified /version:"C%PREV%~C%CURR%" %%g
嘗試:
for /f "tokens=2" %%g in ('tf changeset /noprompt %curr%') do tf diff /noprompt /format:unified /version:C%prev%~C%curr% %%g

HELP FOR
:要在批處理程序中使用 FOR 命令,請指定 %%variable 而不是
%variable。變數名區分大小寫,因此 %i
與 %I 不同。
