Batch replace a language file using grep? - batch-file

Question

I am trying to find/replace a long language file:
$_LANG['accountinformation'] = "Account Information";
$_LANG['accountstatistics'] = "Account Statistics";
to become:
$_LANG['accountinformation'] = "Informations du compte";
$_LANG['accountstatistics'] = "Statistiques du compte";
knowing that I have the whole translation in a file like this:
Informations du compte
Statistiques du compte
Is there a way to replace these phrases with a text editor such as BBedit using grep or something instead of copy/pasting each one of them by hand?

Answer 1

Here is a way to do it using a batch/vbs hybrid script:
#echo off
setlocal
call :FindReplace "Account Statistics" "Statistiques du compte" Thefile.txt
call :FindReplace "Account Information" "Informations du compte" Thefile.txt
exit /b
:FindReplace <findstr> <replstr> <file>
set tmp="%temp%\tmp.txt"
If not exist %temp%\_.vbs call :MakeReplace
for /f "tokens=*" %%a in ('dir "%3" /s /b /a-d /on') do (
for /f "usebackq" %%b in (`Findstr /mic:"%~1" "%%a"`) do (
echo(&Echo Replacing "%~1" with "%~2" in file %%~nxa
<%%a cscript //nologo %temp%\_.vbs "%~1" "%~2">%tmp%
if exist %tmp% move /Y %tmp% "%%~dpnxa">nul
)
)
del %temp%\_.vbs
exit /b
:MakeReplace
>%temp%\_.vbs echo with Wscript
>>%temp%\_.vbs echo set args=.arguments
>>%temp%\_.vbs echo .StdOut.Write _
>>%temp%\_.vbs echo Replace(.StdIn.ReadAll,args(0),args(1),1,-1,1)
>>%temp%\_.vbs echo end with
Change thefile.txt to your filename. Save the script as replace.cmd from a text editor and run it from the command line.

If you are trying to say that the files are aligned -- there is exactly one string definition per line in the English file, and the French contains the translation equivalences in the same order, one per line -- then a simple paste with some postprocessing should do it.
paste strings.def fr.txt |
sed 's/"[^"]*";\t\(.*\)/"\1";/' >output.txt
If your sed dialect doesn't support \t for tab, you'll have to supply a literal tab (ctrl-v tab in many shells).
