Version 1.8.3 Apache License 2.0

Did your source code get polluted by scattered ^M's ?

Endlines smartly converts text files from and to the following line ending conventions : Unix/Apple (LF), Windows (CRLF) and legacy Apple (CR).

endlines unix * 
  • No need to know about the source files' convention. Multiple conventions can be mixed within a single file.
  • Straightforward syntax for multiple files and recursion into directories. Hidden files and directories are skipped by default (you don't want to mess with your .git, do you ?)
  • Binary files will be detected and skipped by default, according to a filter based on both file extension and file content.
  • Files' last access and last modified time stamps can be preserved.
  • UTF-8 files, UTF-16 with BOM as well as all single byte encodings will be treated well. However, UTF-32 is not supported (files will be seen as binary and left untouched).
  • Whether converting or checking, a report is given on the original state of line endings that were found.
    $ endlines check -r .
    endlines : dry run, scanning files

    endlines : 6431 files checked ; found :
                  - 142 No line ending
                  - 1 Legacy Mac (CR)
                  - 6250 Unix (LF)
                  - 37 Windows (CR-LF)
                  - 1 Mixed endings
               2403 binaries skipped
               480 hidden files skipped

Let the help screen say it all :


  ACTION can be :
    lf, unix, linux, osx    : convert all endings to LF.
    crlf, windows, win, dos : convert all endings to CR-LF.
    cr, oldmac              : convert all endings to CR.
    check                   : perform a dry run to check current conventions.

  If no files are specified, endlines converts from stdin to stdout.
  Supports UTF-8, UTF-16 with BOM, and all major single byte codesets.

  General   -q / --quiet    : silence all but the error messages.
            -v / --verbose  : print more about what's going on.
            --version       : print version and license.

  Files     -b / --binaries : don't skip binary files.
            -h / --hidden   : process hidden files (/directories) too.
            -k / --keepdate : keep last modified and last access times.
            -r / --recurse  : recurse into directories.

  Examples  endlines check *.txt
            endlines linux -k -r aFolder anotherFolder


From binaries

The binaries folder contains precompiled binaries for Linux/AMD64 and OSX. You can rename the one that fits you to endlines and move it to /usr/local/bin or to your local path.

From source

  • Local install : make; make test ; if satisfied, move the endlines executable to your local path.
  • Global install : make; make test; sudo make install should suffice.

Operating systems

Endlines is known to have been compiled and run out of the box on Apple OSX, several Linux distributions and IBM AIX. I provide support for all POSIX compliant operating sytems.

Endlines may compile and run on Windows provided the proper POSIX header files are available. I won't provide any support for it, but pull requests helping with Windows support will be welcome.


Version 1.8.3 got a minor fix on convention counts after a Valgrind analysis.

Version 1.8.2 got more verbose when converting standard streams.

Version 1.8.1 should fix the build issue with OSX.

Version 1.8 is safe for concurrent launches. A build issue has been found for Apple OSX.

Version 1.7 embeds the speed and robustness improvements of quickly paced previous versions. I strongly encourage you to upgrade. I removed the tags on purpose. Besides, I don't have a Mac anymore, and this will be the last version that I can compile for OSX by myself. If somebody is willing to provide support with OSX builds, I'll be glad to team up. Please just open an issue.
