Solve Your End-of-line (eol) Problem For Good

I don't want to explain it too much, I understand why you come to this blog

setup for your editor

if you use vscode, create a .vscode/settings.json

{
  "files.eol": "\n"
}

or a much general solution, create a .editorconfig file

[*]
end_of_line = lf

in this way, even if an editor haven't set eol sequence to LF, this will do it for you

for frontend developers

in your .prettierrc file

{
  "endOfLine": "lf"
}

you know what to do next

but it still happens

well, even though you set up these stuffs during developing, eol issue still happens when you clone a repository from a windows user. After your git commit, git saves your code in CRLF on windows, while LF on linux/macos.

to handle this, create a .gitattributes file

* text=auto eol=lf
*.{cmd,[cC][mM][dD]} text eol=crlf
*.{bat,[bB][aA][tT]} text eol=crlf

this config tells git to use LF on saving any file, except .cmd or .bat

not done yet

run following commands to reset eol. Before it, you should make sure your local repository is clean (commit/stash)

git ls-files --eol # inspect if there are files use crlf
git rm --cached -r . # clear git index
git reset --hard

after these, eol in current files will be set to LF
