Re: [edk2-devel] [edk2-libc Patch 1/1] edk2-libc: add .gitattributes to ensure right line endings in .sh .bat

["Jayaprakash, N" <n.jayaprakash@intel.com>]

Regarding the below comment from Lief.

Now, as for the suggestion: this isn't wrong, but can you explain what problem it is solving?

<<JP>> As a developer and also as a maintainer the lines endings have been a consistent problem as I have seen patches coming with mixed line endings some times it take quite a while to fix these simple line ending issues.
I want to start small through .gtiattributes usage for the .sh and .bat scripts to normalize the line endings to LF so that irrespective of the user environment the line endings are always stored as LF in git repo but presented to the users in LF or CRLF as per their environment. Thought of using this feature of github in a lower scale to make it easy for the developers and maintainers of the edk2-libc project. 

If there is a general alignment that this change need not go, then I will close the BZ as won't fix.


Regards,
JP

Hi,

The address I am replying from is the email address I use for tianocore work. Messages sent elsewhere are going to end up misfiled and likely lost.

Technically sort of correct, but see below.

^ This is not a good look for any submission, but especially not one dealing with line endings. Please manually look at patches before sending them out.

Now, as for the suggestion: this isn't wrong, but can you explain what problem it is solving?

I had a look in edk2-libc and all the .sh files have LF line endings and all the .bat files have CRLF line endings.

Now, if we *did* want to do this, I would strongly prefer a patch to edk2/BaseTools/Conf/gitattributes, which is applied in any repo SetupGit.py has been executed in.

But ultimately I want to convert the repos completely to LF line endings except for where special cases exist (which *should* be described in
[.]gitattributes) and then move to enable core.autocrlf.
