Help flag propagated for every module used #14402
Description
Describe the bug
When I run a Nushell script using --help flag, I want to only see the relevant help around main func, but it seems to be propagating to other modules in place as well.
How to reproduce
Create a new script called debugging.nu
#!/usr/bin/env nu
use std/log
def main (data: string = "dummy") {
print $"data: ($data)"
}Then run nu debugging.nu --help, which would yield:
❯ nu debugging.nu --help
Logging module
Log formatting placeholders:
- %MSG%: message to be logged
- %DATE%: date of log
- %LEVEL%: string prefix for the log level
- %ANSI_START%: ansi formatting
- %ANSI_STOP%: literally (ansi reset)
Note: All placeholders are optional, so "" is still a valid format
Example: $"%ANSI_START%%DATE%|%LEVEL%|(ansi u)%MSG%%ANSI_STOP%"
Usage:
> debugging.nu
Flags:
-h, --help: Display the help message for this command
Input/output types:
╭───┬───────┬────────╮
│ # │ input │ output │
├───┼───────┼────────┤
│ 0 │ any │ any │
╰───┴───────┴────────╯
======================
Usage:
> debugging.nu (data)
Flags:
-h, --help: Display the help message for this command
Parameters:
data <string>: (optional, default: 'dummy')
Input/output types:
╭───┬───────┬────────╮
│ # │ input │ output │
├───┼───────┼────────┤
│ 0 │ any │ any │
╰───┴───────┴────────╯Expected behavior
I expect the help message will only show from the main function of the target file (in this case debugging.nu's main function only)
