# Check how files in the repo are changed when they are checked out
# How to read the table below:
# - checkout_files will check multiple files with a combination of settings
# and attributes (core.autocrlf=input is forbidden with core.eol=crlf)
# - parameter $1 : core.eol lf | crlf
# - parameter $2 : core.autocrlf false | true | input
# - parameter $3 : text in .gitattributs "" (empty) | auto | text | -text
# - parameter $4 : reference for a file with only LF in the repo
# - parameter $5 : reference for a file with only CRLF in the repo
# - parameter $6 : reference for a file with mixed LF and CRLF in the repo
# - parameter $7 : reference for a file with LF and CR in the repo (does somebody uses this ?)
# - parameter $8 : reference for a file with CRLF and a NUL (should be handled as binary when auto)
# What we have in the repo:
# ----------------- EOL in repo ----------------
# LF CRLF CRLF_mix_LF LF_mix_CR CRLF_nul
# settings with checkout:
# core. core. .gitattr
# eol acrlf
# ----------------------------------------------
# What we want to have in the working tree:
