How to have EOL=LF and keep binary files auto-detection?

How to have EOL=LF and keep binary files auto-detection?

[Kirill Likhodedov]

Hi, 

I wonder if it is possible both to have LFs in all and only text files in working trees, and keep Git’s binary files auto-detection?

To be more precise:
* we want all text files to be checked out in LF; 
* we don’t want force people to set “core.autocrlf” to false, preferring to keep this configuration in .gitattributes; 
* we obviously don’t want binary files to be touched by eol-normalization; 
* we also don’t want to declare all possible patterns of binary files - Git is good enough in detecting them automatically.

However, I’ve found no way to do so.

If I declare `* eol=lf` in .gitattributes, it makes Git treat all files as text and thus convert CRLF to LF even in binary files. It is consistent with man, but a bit surprising to have e.g. a zip or png file modified in this way.

One could expect `* text=auto eol=lf` to work the way we want, but unfortunately it doesn’t work either: “eol=lf” forces “text” on all files.

Thanks a lot for your help!

The short answer: Git doesn't currently do that.
The closest you can get, is to use
echo "* text=auto" >.gitattributes
and
git config core.eol lf
git config core.autocrlf false.

The longer answer is, that I am working on a patch to allow just
the combination of "* text=auto eol=lf" to work as you want it.

Which platform do you use ?
And (out of curiosity, why do you want text files with LF ?)

If you are willing to compile and install Git yourself,
you can use the branch here:
https://github.com/tboegi/git/commits/160421_0706_reliable_t0027_allow_TC_combined_ident_CRLF_v7

Feedback is welcome, if it works as expected.

Thank you for the information.

We create products (IDEs for different programming languages) for the
three major platforms (Window/Linux/Mac OSX). Our products are written
in Java and we want to minimize differences between distributions for
different platforms, so we use LF separators for all resource files.
