clap-rs VS komorebi

We will be using the library for Clap - A simple-to-use, efficient, and full-featured library for parsing command line arguments and subcommands.

I recently came across this question (and associated answer) on the clap repository. The answer given is a good one. But I wanted to expand with my own findings and practices, which spurred the motivation for this post.

We can also use tuple-like struct syntax and named-field struct syntax for enum variants within our enum; this is because unlike in other OOP languages, Rust enums are actually sum types. You can read more about how powerful Rust enums are in another article we wrote here. You can have optional arguments by simply wrapping the types in Option, but if you want to add a flag to a command you can use bool, since clap recognises that flags are either there or not there. Let's have a look at what this might look like:

I began by developing a wrapper for the CurseForge API, which turned out to be a lengthy and challenging process but constituted the bulk of the work. Next, I coded the CLI, which was relatively straightforward. Instead of using the clap crate, a Rust tool for generating CLIs, I opted for the following line of code:

By this time I had already gotten tired of parsing arguments by myself and had looked for something to help with that. I found a really dang good argument parsing library called clap. What makes it so cool is it's largely declarative for common uses. You simply mark up a struct with attributes, and the parser automatically generates the usage and all the argument parsing code.

How CLI arguments are handled (using clap).

Is this just referring to wrapping based on the terminal width? That is supported with the wrap_help feature though I have been considering making it a default feature.

CLI, use Clap. If you want to get fancy, use Tui.

As our CLI is getting more complex, we'll use the clap crate to parse the command line arguments.

I love seeing whenever this is (re)posted.

This article had such a huge impact on my life and led to me creating many pieces of software[1][2][3] that were hyper-specific to myself and my needs at the time, which also later found an audience in others who think and work in ways similar to me.

[1]: https://notado.app - a "content-first" internet bookmarking and highlighting service which has been my second brain since 2020 after growing frustrated with Instapaper, Pinboard and Readwise. Eventually I expanded this to allow for RSS feed publishing on specific topics in an attempt to solve the "firehose" problem when following other peoples' bookmarks/shares, and at the end of last year I added what is now my most used feature of image generation from highlights for sharing on image-first/text-hostile social media platforms.

[2]: https://github.com/LGUG2Z/komorebi - tiling window manager for Windows. There wasn't really anything fit for purpose on Windows when I started, and I was too spoiled by bspwm and yabai on Linux and macOS that I just had to write something before I could become a truly productive Windows user. I'm astonished that this now has 50k+ downloads.

[3]: https://kulli.sh - I use this to aggregate comments from HN/Reddit/Lemmy/Lobsters on an article I'm interests in in one place to read. This has helped me find some interesting niche communities on Reddit and Lemmy who share and discuss things I'm interested in that I otherwise wouldn't have found.

It's very heartening to see all of the stories here.

I've put the last few years of my life into working on komorebi, a tiling window manager for Windows[1], https://notado.app, a content-first social bookmarking service, and https://kulli.sh, a "bring your own links" comment aggregator which shows you comments from hn, reddit, lobsters, lemmy etc. on an article all in one place.

Unfortunately I was laid off after 5 years with the same company last month, and nobody seems to care about any of these projects when it comes to recruiting. There are people who use them that have reached out to me very kindly offering to make referrals, but the job market values LeetCode more than shipping real code these days.

In the spirit of full disclosure, I wanted to share that throughout the changeset of this refactor which included 11 files changed, 597 insertions, and 133 deletions (full diff here), a single regression was found due to a logic error I introduced.

The two biggest tiling window manager projects for Windows are komorebi and GlazeWM. Komorebi is probably faster and more resource efficient since it is written in Rust, but I stick with Glaze for now since it has a cool status bar built in I like.

Not too many options for Windows OS, but this one looks decent: https://github.com/LGUG2Z/komorebi.

It's been a while since I last posted here. Since my last post, komorebi passed 3k stars on GitHub, became the most starred Windows twm of all time (surpassing bug.n!) and crossed 20k downloads.

This is pretty depressing. I'm pretty involved in the ricing side of the Windows ecosystem[1] and there is a lot of work going on in this space to allow users to get rid of the start bar entirely and replace it with something more functional. I would love for the day when there could just be a user friendly drop-in replacement.
