I can put my commands in a run file, which source a simple bash script, and use it like:
run do-foo
run build-bar
The setup is explained here: https://olivernguyen.io/w/direnv.run/
#!/bin/bash
set -eo pipefail
run-hello() {
echo "Hello, World!"
}
# -------- this is the magic ------- #
source "scripts/_cli.sh"
#!/bin/bash
set -eo pipefail
show-help(){
items=()
while IFS='' read -r line; do items+=("$line"); done < \
<(compgen -A "function" | grep "run-" | sed "s/run-//")
printf -v items "\t%s\n" "${items[@]}"
usage="USAGE: $(basename "$0") CMD [ARGUMENTS]
CMD:\n$items"
printf "$usage"
}
name=$1
case "$name" in
"" | "-h" | "--help" | "help")
show-help
;;
*)
shift
if compgen -A "function" | grep "run-$name" >/dev/null ; then
run-"${name}" "$@"
else
echo "ERROR: run-$name not found."
exit 123
fi
