`: another option
# Flags
- `-f, --flag`: a flag
"""
@main function main(x; opt1=1, opt2::Int=2, flag=false)
println("Parsed args:")
println("flag=>", flag)
println("arg=>", x)
println("opt1=>", opt1)
println("opt2=>", opt2)
end
```
## Zero Dependency
Comonicon can generate a human readable Julia script that contains one function `command_main` to process your command line interfaces that has zero dependency on Comonicon itself. Thus after you generate the script, you can choose to remove Comonicon itself.
# Planned Features
- shell auto-completion
- distributable system image (so users don’t need to compile it locally but download as an artifact)
Fore more details about this package please refer to the website: [https://rogerluo.me/Comonicon.jl/](https://rogerluo.me/Comonicon.jl/) and the doc: [https://rogerluo.me/Comonicon.jl/dev/](https://rogerluo.me/Comonicon.jl/dev/)

Excellent work. This look quite useful.

SHELL completion for ZSH is supported in the new v0.5 version, the system image CI is also supported using a new build system. I think all planned features are at least implemented now.
still need BASH support, if someone knows how to write BASH autocompletes. and I’m not sure about how to support command lines for Windows given it’s in powershell.
I also registered the IonCLI, which I will make an announcement about it later, but you can see how the system image works in the CI and get downloaded automatically via this project.

This is fantastic. To me, scripts are always better as CLIs and the first thing I looked for when starting my latest project was a way to compile and install my package with a CLI entry point. This is exactly what I needed.
Just a few little issues I worked through setting it up:
- The doc page here seems to be 404: [https://rogerluo.me/Comonicon.jl/dev/](https://rogerluo.me/Comonicon.jl/dev/)
- The `Comonicon.install` method doesn’t seem to be documented
- The `Comonicon.install` workflow example on your homepage shows calling it like `Comonicon.install(Dummy, "dummy")` but the actual method wasn’t expecting the second string argument, just `Comonicon.install(Dummy)`.
- Your project website and docs don’t seem to mention the Comonicon.toml file, at least I couldn’t find where that was documented.
Seeing the example of how you use it in your IonCLI project [https://github.com/Roger-luo/IonCLI.jl](https://github.com/Roger-luo/IonCLI.jl) was very helpful, I was able to figure out how to use the package based on that.

Thanks! I’ll update the documentation soon. It seems Documenter somehow removes all the old docs but only the latest stable version. I’ll check that first.
The tutorial in this documentation is a bit out of date indeed, since we had quite a few changes since it was written, I’ll update this too. I might take some knowledge for granted, which makes it hard for people to understand what happens and how to use it, so please feel free to correct docs as well!

Now in Comonicon v0.9, it has a new tutorial [https://rogerluo.me/Comonicon.jl/dev/](https://rogerluo.me/Comonicon.jl/dev/) with a new configuration system: [https://rogerluo.me/Comonicon.jl/dev/configurations/](https://rogerluo.me/Comonicon.jl/dev/configurations/)
and now it supports building standalone CLI app, e.g you can download IonCLI directly without depending on an external julia compiler: [https://github.com/Roger-luo/IonCLI.jl/releases/tag/v0.8.0](https://github.com/Roger-luo/IonCLI.jl/releases/tag/v0.8.0)
