TYPO3 Core

If an included TypoScript-file is edited in the Backend (Template -> Info/Modify -> Setup) the line breaks will be saved as CRLF. In accordance with the Coding Guidelines LF should always be used.

Precondition: t3editor (Editor with syntax highlighting) is NOT installed. The use of t3editor seems to solve this issue, but has other issues like converting tablulators to spaces.

• Create a new textfile "fileadmin/setup.ts" via Filelist
• Include this in the Setup of a new Template:
  

  <INCLUDE_TYPOSCRIPT: source="FILE: fileadmin/setup.ts">

• Select the "Include TypoScript file content" option
• Enter some content (manual):
  

  page = PAGE
  page{
      10 = TEXT
      10.value = Hello World!
  }

• Save
• View the file with a Texteditor that can display line endings (f.e. Notepad++)

The problem may be that the Browser (Firefox 25.0.1, OS X, in my case) sends the <textarea>-content with CRLF.
A solution could be to convert all CRLF to LF before writing to the file.
