Ask HN: What do you use to make CLIs?
I use a lot of CLI tools, but haven't written many for myself. Mostly, aliases/functions and some scripts in Bash/Python.
Extract details for command options from man/help: https://github.com/learnbyexample/command_help/blob/master/c...
cut-like syntax for field manipulations with regexp, negative indexing, etc: https://github.com/learnbyexample/regexp-cut/blob/main/rcut
simple calculator using python syntax: https://learnbyexample.github.io/practice_python_projects/ca...
- A better way of displaying help text on the command line
-
Enter a command to see help text for each arg
I wrote a Linux CLI tool [0] that parses the man/help pages to extract option details. Works most of the time for me, but there are plenty of corner cases that don't work.

What tools / utilities have you written that you use regularly?

What's a program you made that you actually use regularly?
https://github.com/learnbyexample/command_help is big enough to warrant a repo, examples, limitations, etc. I had a list of todo items to improve the script, but after years of usage, I'm fine with the limitations since I rarely encounter them. This helps me to extract documentation of particular options, here's an example:
-
Save Time Using Manop to Print Only Selected Content From the Man Page using Manop
I wrote one a few years back (https://github.com/learnbyexample/command_help). It has a few corner case issues, but works most of the time for me and supports multiple options to be retrieved.

Explainshell - A tool that takes any shell commands, looks up the syntax and options from man pages, and steps you through what it does!
I particularly wanted to lookup documentation for command options from my terminal (instead of the website), so wrote a script for it: https://github.com/learnbyexample/command_help ... Have a long pending todo list, but despite the issues, the tool is good enough for my needs.

Testing
When I start a project, I usually try to write the programs incrementally. Say I need to iterate over files from a directory. I will make sure that portion is working (usually with print() statements), then add another feature — say file reading and test that and so on. This reduces the burden of testing a large program at once at the end. And depending upon the nature of the program, I'll add a few sanity tests at the end. For example, for my command_help project, I copy pasted a few test runs of the program with different options and arguments into a separate file and wrote a program to perform these tests programmatically whenever the source code is modified.

FAQ on the xz-utils backdoor – via a project dev
Reminds of the note at the bottom of Fish's releases. It's there because the build system cannot determine the current version for some reason. Hopefully that will go away now that they have switched to a different language / build system. The custom tarball is used by Arch Linux at the very least.

- Proposal for porting fish-shell from C++ to Rust

Converting the Kernel to C++
A recent practical example of the former: the fish shell re-wrote incrementally from C++ to Rust, and is almost finished https://github.com/fish-shell/fish-shell/discussions/10123
An example of the latter: c2rust, which is a work in progress but is very impressive https://github.com/immunant/c2rust
It currently translates into unsafe Rust, but the strategy is to separate the "compile C to unsafe Rust" steps and the "compile unsafe Rust to safe Rust" steps. As I see it, as it makes the overall task simpler, allows for more user freedom, and makes the latter potentially useful even for non-transpiled code. https://immunant.com/blog/2023/03/lifting/

Fish shell 3.7.0: last release branch before the full Rust rewrite
And this discussion from November has an update on the progress: https://github.com/fish-shell/fish-shell/discussions/10123

Day 5 - More or less...
We're using bash as our terminal shell for now (it is standard in many distros) but it is not the only one out there. If you want to test out zsh, fish or oh-my-zsh, you will see that there are a few differences and the features are usually the main differentiator. Try that, poke around.

Fish – Update on the Rust Port
They have a variety of reasons to move to rust, as outlined in their original rust discussion[1]. Mostly around finding other contributors, and adding an async/parallel mode they're comfortable with.
