# Klask

Allows you to create a gui application automatically from clap (v3). Uses egui for graphics. [Changelog](CHANGELOG.md)

## Features

- Supports flags with multiple occurrences (`-vvv`)

- Has a native path picker

- Supports fields with multiple values

- Output is colored and has clickable links

- Combo boxes for arguments with only some values allowed

- Subcommands

- Optionally allow setting environment variables, stdin and working directory

- Progress bars

If you are using this library please contact me, I'm definitely interested!

## How it works

* The binary runs and there's no `CHILD_APP_ENV_VAR` environment variable ⇾ no user code runs, only the GUI is displayed.

* The "Run" button in the GUI is pressed ⇾ `CHILD_APP_ENV_VAR` is set, the binary is started again. Arguments are passed to `stdin` and `stdout` is intercepted for displaying output.

* The binary is run with `CHILD_APP_ENV_VAR` ⇾ the user-provided closure is run.
