# THAST canonical line-ending policy — master copy.
#
# This is the single source of truth for line-ending normalisation across every
# THAST repository. It is deployed two ways (see git/LINE-ENDINGS.md):
#   1. Per-repo: copied to each repo as a committed .gitattributes — authoritative,
#      travels with every clone, wins over global config, and is honoured by CI.
#   2. Fleet-wide safety net: symlinked to ~/.gitattributes_global and referenced
#      by core.attributesfile, so repos that have not yet adopted the per-repo file
#      still normalise on machines where install.sh has run.
#
# Why LF everywhere: text is stored as LF in the repository and checked out as LF
# on macOS, Linux and WSL/Windows alike. This keeps working trees byte-identical
# across machines — essential where one checkout is shared over a cross-OS mount
# (e.g. a WSL node reading a /mnt/c path) or byte-synced by Syncthing, and so a
# shell shebang never carries a stray CR that breaks the interpreter.

# Default: auto-detect text vs binary; store anything textual as LF.
* text=auto eol=lf

# Executable scripts — LF is mandatory. A trailing CR in the shebang yields
# "bad interpreter: /bin/bash^M" under WSL/Linux.
*.sh    text eol=lf
*.bash  text eol=lf
*.zsh   text eol=lf
*.ps1   text eol=lf

# Windows batch files genuinely require CRLF to parse reliably.
*.bat   text eol=crlf
*.cmd   text eol=crlf

# SVG is XML — keep it text and diffable, but pinned to LF.
*.svg   text eol=lf

# IMPORTANT: *.ts is TypeScript across the THAST fleet, NOT an MPEG transport
# stream. It must remain text — never add *.ts to the binary list below.
