{
name, # the name of the derivation
files,
executable ? false, # run chmod +x ?
destination ? "", # relative path appended to $out eg "/bin/foo"
checkPhase ? "", # syntax checks, e.g. for scripts
meta ? { },
passthru ? { },
}:
runCommandLocal name
{
inherit
files
executable
checkPhase
meta
passthru
destination
;
}
''
file=$out$destination
mkdir -p "$(dirname "$file")"
cat $files > "$file"
if [ -n "$executable" ]; then
chmod +x "$file"
fi
eval "$checkPhase"
'';
