How to change line-ending settings

Question

Is there a file or menu that will let me change the settings on how to deal with line endings?

There are 3 options:

1. Checkout Windows-style, commit Unix-style

   Git will convert LF to CRLF when checking out text files. When committing text files, CRLF will be converted to LF. For cross-platform projects, this is the recommended setting on Windows ("core.autocrlf" is set to "true")

2. Checkout as-is, commit Unix-style

   Git will not perform any conversion when checking out text files. When committing text files, CRLF will be converted to LF. For cross-platform projects this is the recommended setting on Unix ("core.autocrlf" is set to "input").

3. Checkout as-is, commit as-is

   Git will not perform any conversions when checking out or committing text files. Choosing this option is not recommended for cross-platform projects ("core.autocrlf" is set to "false")

Answer 1

The normal way to control this is with git config

For example

git config --global core.autocrlf true

For details, scroll down in this link to Pro Git to the section named "core.autocrlf"

If you want to know what file this is saved in, you can run the command:

git config --global --edit

and the git global config file should open in a text editor, and you can see where that file was loaded from.

Line ending format used in OS

• Windows: CR (Carriage Return \r) and LF (LineFeed \n) pair
• OSX,Linux: LF (LineFeed \n)

We can configure git to auto-correct line ending formats for each OS in two ways.

1. Git Global configuration
2. Use .gitattributes file

Global Configuration

In Linux/OSX

git config --global core.autocrlf input

This will fix any CRLF to LF when you commit.

In Windows

git config --global core.autocrlf true

This will make sure when you checkout in windows, all LF will convert to CRLF

.gitattributes File

It is a good idea to keep a .gitattributes file as we don't want to expect everyone in our team set their config. This file should keep in repo's root path and if exist one, git will respect it.

* text=auto

This will treat all files as text files and convert to OS's line ending on checkout and back to LF on commit automatically. If wanted to tell explicitly, then use

* text eol=crlf
* text eol=lf

First one is for checkout and second one is for commit.

*.jpg binary

Treat all .jpg images as binary files. So no conversion needed

For a repository setting solution, that can be redistributed to all developers, check out the text attribute in the .gitattributes file. This way, developers dont have to manually set their own line endings on the repository, and because different repositories can have different line ending styles, global core.autocrlf is not the best, at least in my opinion.

For example unsetting this attribute on a given path [. - text] will force git not to touch line endings when checking in and checking out. In my opinion, this is the best behavior, as most modern text editors can handle both type of line endings. Also, if you as a developer still want to do line ending conversion when checking in, you can still set the path to match certain files or set the eol attribute (in .gitattributes) on your repository.

If you want to convert back the file formats which have been changed to UNIX Format from PC format.

(1)You need to reinstall tortoise GIT and in the "Line Ending Conversion" Section make sure that you have selected "Check out as is - Check in as is"option.

(2)and keep the remaining configurations as it is.

(3)once installation is done

(4)write all the file extensions which are converted to UNIX format into a text file (extensions.txt).

ex:*.dsp
   *.dsw

(5) copy the file into your clone Run the following command in GITBASH

while read -r a;
do
find . -type f -name "$a" -exec dos2unix {} \;
done<extension.txt
