Repository for testing Git EOL conversion using .gitattributes

Checkout defaulting to LF

For any of the following configurations:

Configuration	core.autocrlf	core.eol
1	false	lf
2	input	any

The result of git ls-files --eol testfiles after checkout should be:

i/lf    w/crlf  attr/text=auto eol=crlf testfiles/auto.crlf
i/lf    w/lf    attr/text=auto eol=lf   testfiles/auto.lf
i/lf    w/lf    attr/text=auto          testfiles/auto.native
i/-text w/-text attr/text=auto          testfiles/binary.auto
i/-text w/-text attr/text=auto eol=crlf testfiles/binary.auto.crlf
i/-text w/-text attr/text=auto eol=lf   testfiles/binary.auto.lf
i/crlf  w/crlf  attr/-text              testfiles/binary.explicit.crlf
i/lf    w/lf    attr/-text              testfiles/binary.explicit.lf
i/lf    w/crlf  attr/text eol=crlf      testfiles/text.crlf
i/lf    w/lf    attr/text eol=lf        testfiles/text.lf
i/lf    w/lf    attr/text               testfiles/text.native

(i = index, w = working directory)

Checkout defaulting to CRLF

For any of the following configurations:

Configuration	core.autocrlf	core.eol
3	false	crlf
4	true	any

The result of git ls-files --eol testfiles after checkout should be:

i/lf    w/crlf  attr/text=auto eol=crlf testfiles/auto.crlf
i/lf    w/lf    attr/text=auto eol=lf   testfiles/auto.lf
i/lf    w/crlf  attr/text=auto          testfiles/auto.native
i/-text w/-text attr/text=auto          testfiles/binary.auto
i/-text w/-text attr/text=auto eol=crlf testfiles/binary.auto.crlf
i/-text w/-text attr/text=auto eol=lf   testfiles/binary.auto.lf
i/crlf  w/crlf  attr/-text              testfiles/binary.explicit.crlf
i/lf    w/lf    attr/-text              testfiles/binary.explicit.lf
i/lf    w/crlf  attr/text eol=crlf      testfiles/text.crlf
i/lf    w/lf    attr/text eol=lf        testfiles/text.lf
i/lf    w/crlf  attr/text               testfiles/text.native

(i = index, w = working directory)

Check-in

Any modified file in the working directory that is recognized as a text file (e.g. auto.* and text.* in the above) that contains CRLF line endings will be converted to LF in the index upon check-in (i.e. git add). This can be verified using git ls-files --eol as in the above.

Additional notes

• core.autocrlf = false is equivalent to core.autocrlf being unset, i.e. the default
• core.autocrlf = true overrides core.eol, as if core.eol = crlf was set
• Both core.autocrlf = true and core.autocrlf = input have the effect of setting a default text=auto attribute on all files (which may be overridden on a file-by-file basis by attribute specifications in .gitattributes etc.)
• core.eol is only relevant for checkout, never for check-in. Conversion from CRLF to LF always takes place for text files on check-in, regardless of core.eol or core.autocrlf.
• core.eol = crlf is equivalent to core.eol = native on Windows
• core.eol = lf is equivalent to core.eol = native on non-Windows systems (including Cygwin)
• core.eol = native is equivalent to core.eol being unset, i.e. the default
• In .gitattributes, the eol attribute defaults to the effective value of core.eol, i.e. possibly overridden by core.autocrlf = true (only relevant in context of a text attribute being set for a file)
• The effective eol attribute determines whether conversion from LF to CRLF takes place for a text file upon checkout. (The reverse conversion, i.e. from CRLF to LF, never takes place on checkout.)
