Is there a way to add alias "help" to fixed_flags_filter ? about bashly

[DannyBen]

Not as an alias. Adding a cli help is actually equivalent to adding a command.
You can easily do it using this bashly.yml setup:

name: cli
help: Sample application
version: 0.1.0

commands:
- name: help
  help: Show help

and after running bashly g, you will get the src/help_command.sh placeholder - put this content in it:

long_usage=yes
cli_usage

which is exactly what is being called when you run cli --help.

Does this work for you?

---

The nice thing about this, is that you can also adopt this function to allow cli help COMMAND to get help for different commands.

See this example for a nice implementation.

Well for all commands I get
No help available for this command
I wonder what am I doing wrong?

I also found another solution
with
extensible: true
and cli-help script
but your seems more practical

Well, look at your generated script, and search for "--help" to see which function it calls.

All the occurrences of cli_* in the example, should be replaced with your script name (the cli prefix is the name of the default script) - lines 6 and 9 below.

bashly/examples/help-command/src/help_command.sh

Lines 4 to 10 in 46c0f4e

	if [[ -z "$command" ]]; then
	# No command argument, show the global help
	help_function=cli_usage
	else
	# Show the help for the requested command
	help_function="cli_${command}_usage"
	fi

As for the extensible option, it is not intended for it, although it can be used for it.
Bashly's goal is to have everything you need to write a good bash script in it. The extensible option is meant for you to give the users of your script the ability to extend it themselves if they want.
