.gitattributes

# In .gitattributes the LAST matching rule wins. That is why the general rule
# comes first and the testdata/ exception comes last. Inverting the order lets
# `*` override `testdata/**` and Git normalises the corpus.

# General rule for the repository's own code.
* text=auto eol=lf

*.rs      text eol=lf
*.ts      text eol=lf
*.tsx     text eol=lf
*.json    text eol=lf
*.toml    text eol=lf
*.md      text eol=lf
*.html    text eol=lf
*.css     text eol=lf

# ---------------------------------------------------------------------------
# CRITICAL FOR THIS PROJECT
#
# The test corpus must be preserved byte for byte. Git normalises line endings
# by default, which would turn CRLF into LF on commit and destroy the parser's
# round-trip guarantee: 698 of 725 files are CRLF and 557 do not end in a
# newline.
#
# `-text` disables every EOL conversion. `-diff` treats them as binary in
# diffs, which also avoids useless thousand-line diffs.
#
# This rule must stay last in the file. Do not move it.
