Batch Script breakline on spaces?

I'm using the following piece of code; to change something in a Cmakefile:

for /f %%j in (CMakeLists.txt) do (
 if "%%j"=="Extensions_AntTweakBar" (
  echo #Extensions_AntTweakBar >> temp.tmp 
 ) else (
  if "%%j"=="Extensions_Inspection" (
   echo #Extensions_Inspection >> temp.tmp
  ) else (
      if "%%j"=="Extensions_InspectionBar" (
    echo #Extensions_InspectionBar >> temp.tmp
   ) else (
    echo %%j >> temp.tmp
   )
  )
 )
)

I开发者_如何学JAVAt seems to work, that is, it does change the selected lines, however, if theres a space on one line, it only gets that line till the space occurs. Example:

SET( PROJECT_NAME "MyProject")

Only gets the string:

SET(

How am I supposed to get the full string then?

In your code you append a space at each line.

echo %%j[space]>> temp.tmp

Here you can remove it(works only with %%j), but normally it is better to set the redirection as prefix, like

>> temp.tmp echo %%j

With a normal variable the postfix variant could fail

set var=hallo2
echo %var%>temp.tmp

Expands to echo hallo2>temp.tmp or echo hallo 2> temp.tmp, so only the stderr would redirected. The next problem are the keywords ON OFF /?, if your file contains such a word you get unexpected results, because the echo interprets these words.

[EDIT:] To solve this you can use echo(

>>temp.tmp echo(%%j

You can get empty lines (or lines with only whitespaces), you simply need to prefix them.

for /f "delims=" %%a in ('findstr /n ".*" qut.bat') do (
    set var=%%a
    setlocal EnableDelayedExpansion
    echo(!var:*:=!
    endlocal
)

The toggling of the DelayedExpansion is neccessary to preserve "!" and "^" characters

The default delimiters are space and tab. If you override the default delimiter, it should read the entire line with spaces in between

for /f "delims=@" %%j in (CMakeLists.txt) do

I set it to @, and it ignores space as delimiter and reads the entire line. You can set it a unique character that you know will not be in the text file.
