# Everything executable here runs on Linux: the containers, the CI
# runners, the cloud nodes. A shell script checked out with CRLF is not
# a shell script with cosmetic differences — it does not run at all:
#
#   /usr/bin/env: 'bash\r': No such file or directory
#
# The shebang becomes `bash\r`, which is not a program. The failure
# surfaces as exit 127 from whatever invoked it, naming no file and no
# reason, and it is invisible to CI because CI checks out on Linux.
#
# Git for Windows ships with core.autocrlf=true in its system config, so
# this is the default experience for a Windows contributor rather than a
# misconfiguration. It also spreads quietly: only files Git actually
# rewrites are converted, so a checkout can be half LF and half CRLF, and
# a script that worked yesterday stops after an unrelated merge touches
# it. That is how it was found — `make test-all` failed on two scripts
# and passed on fifty-eight.
#
# A .gitattributes rule beats core.autocrlf, so this fixes the repository
# for everyone without anyone having to change their global settings.

# Normalise every text file in the repository to LF in the index and in
# the working tree. `text=auto` lets Git decide what is text; `eol=lf`
# says what to do when it is.
* text=auto eol=lf

# Named explicitly rather than left to detection. These are the files
# whose CRLF failure mode is total rather than cosmetic.

*.bash      text eol=lf

# The fake-bin shims deliberately have no extension — they stand in for
# `vault`, `aws`, `curl` and must be named exactly that to be found on
# PATH — so no suffix rule reaches them.

# Templates that render into shell.
*.tftpl     text eol=lf

# Binary, and must never be touched. Git's own detection is usually
# right about these, but "usually" is not a property worth relying on
# for the file that renders every link to this repository.
