# This function is compatible with clang, clang++, and variations thereof, and is shared
# by clang.fish and clang++.fish.
# We dynamically query the head at `(commandline -o)[1]` to get the correct completions.
function __fish_clang_complete
# If the result is for a value, clang only prints the value, so completions
# for `-std=` print `c++11` and not `-std=c++11` like we need. See #4174.

# first get the completions from clang, with the prefix separated from the value by a comma
$clang --autocomplete=(commandline -ct | string unescape | string replace -- "$prefix" "$prefix,") 2>/dev/null |
