# Shell Hell 🙃
## What is it
One day I was thinking about a simple task: make a script-like program with proper CLI and pack it into a standalone executable. There was no particular need in the program itself, I just wanted to research as many ways to do it as possible — am I a language geek or not? 😜
Here I'm collecting examples made using stacks I tried so far. Below will be a complete list.
But first let's see the task's conditions.
### Task
1. Each program should be standalone, i.e. "download and run". Ideally, a single binary executable. Here I'm testing the **packaging**.
2. Program should have a rich Command Line Interface with inline help & stuff. Here I'm testing the expressiveness of **CLI-building libs/DSLs**.
3. Program should be able to call external programs and let me write such code easily. Here I'm testing the expressiveness of **shell-scripting capabilities**.
Each program expects a single argument — string prefix. Then it should run the pipeline `grep ^PREFIX /usr/share/dict/words | wc -l` that will count each word int dictionary that starts with the prefix. Yes, I usually can do such calculations programmatically. But I want to be able to **compose existing tools** and wish to do it in a way as much close to bash/zsh/sh, as it possible in each language stack.
## Experiments
| Language | Executable size | Stripped |
|:--------------------------:|:---------------:|:--------:|
| [Python](./python) | 10 MB 🫤 | breaks |
| [Rust](./rust/) | 1.1 MB ☺️ | 908 KB |
| [Haskell](./haskell/) | 4.2 MB 🫣 | 3.1 MB |
| [Racket](./racket/) | 56 MB 🙈 | 55 MB |
| [Kotlin/Native](./kotlin/) | 2.6 MB 👌 | 1.9 MB |
| [Swift](./swift/) | 1.5 MB ☺️ | 808 KB |
| [Scala/GraalVM](./scala/) | 14 MB 🫤 | 14 MB |
