cligen VS awesome-selfhosted

There is also generating the whole thing from a function signature (e.g. https://github.com/c-blake/cligen ) since then CLauthors need not learn a new spec language, but then CLauthors must add back in helpful usage metadata/semantics and still need to learn a library API (but I like how those two things can be "gradual"). It's a hard space in which to find perfection, but I wish you luck in your attempt!

cligen also allows End-CL-users to adjust colorization of --help output like https://github.com/c-blake/cligen/blob/master/screenshots/di... using something like https://github.com/c-blake/cligen/wiki/Dark-BG-Config-File

Last I knew, the argparse backing most Py CLI solutions did not support such easier (for many) to read help text, but the PyUniverse is too vast to be sure without much related work searching.

20 milliseconds? On my 7 year old Linux box, this little Nim program https://github.com/c-blake/bu/blob/main/wsz.nim runs to completion in 275 microseconds when fully statically linked with musl libc on Linux. That's with a stripped environment (with `env -i`). It takes more like 318 microseconds with my usual 54 environment variables. The program only does about 17 system calls, though.

Additionally, https://github.com/c-blake/cligen makes decent CLI tools a real breeze. If you like some of Go's qualities but the language seems too limited, you might like Nim: https://nim-lang.org. I generally find getting good performance much less of a challenge with Nim, but Nim is undeniably less well known with a smaller ecosystem and less corporate backing.

If you find this article interesting and are curious about Nim then you would probably also be curious about https://github.com/c-blake/cligen

That allows adding just 1-line to a module to add a pretty complete CLI and then a string per parameter to properly document options (assuming an existing API using keyword arguments).

It's also not hard to compile & link a static ELF binary with Nim.. I do it with MUSL libc on Linux all the time. I just toss into my ~/.config/nim/nim.cfg:

    @if musl:  # make nim c -d:musl .. foo static-link `foo` with musl

Sure. No problem.

Even Windows has popen these days. There are some tiny popenr/popenw wrappers in https://github.com/c-blake/cligen/blob/master/cligen/osUt.ni...

Depending upon how balanced work is on either side of the pipe, you usually can even get parallel speed-up on multicore with almost no work. For example, there is no need to use quote-escaped CSV parsing libraries when you just read from a popen()d translator program producing an easier format: https://github.com/c-blake/nio/blob/main/utils/c2tsv.nim

Nim is terse yet general and can be made even more so with effort. E.g., You can gin up a little framework that is even more terse than awk yet statically typed and trivially convertible to run much faster like https://github.com/c-blake/bu/blob/main/doc/rp.md

You can statically introspect code to then generate related/translated ASTs to create nearly frictionless helper facilities like https://github.com/c-blake/cligen .

You can do all of this without any real run-time speed sacrifices, depending upon the level of effort you put in / your expertise. Since it generates C/C++ or Javascript you get all the abilities of backend compilers almost out of the box, like profile-guided-optimization or for JS JIT compilation.

It's more that those tools were what come to mind when I specifically think of my exposure to the existence of rust. Its perhaps not that the tools were there, but that they were well known (and known for being written in rust).

Anecdatapoint - I've never heard of literally a single one of the utilities listed on the bu page.

Regarding cligen, right from the start clap wins on producing idiomatic output. Compare: https://github.com/c-blake/cligen#cligen-a-native-api-inferr...

    Usage:

cool example would be this which is a CLI generation library. It lets you describe command line interfacs simply using function signatures

>Does nim have anything as polished and performant as clap and serde?

"Polished" and "high quality" are more subjective/implicitly about adoption, IMO. "Performant" has many dimensions. I just tested the Nim https://github.com/c-blake/cligen vs clap: cligen used 5X less object file space (with all size optimization tweaks enabled in both), 20% less run-time memory for large argument lists, and the same run-time per argument (with march=native equivalents on both, within statistical noise). cligen has many features - "did you mean?/suggestions", color generated help and all that - I do not see obvious feature in clap docs missing in cligen. The Nim binary serde showing is unlikely as good but there are like 10 JSON packages and that seems maybe your primary concern.

More to add color your point than disagree (and follow up on my "adoption") - your ideas about polish, quality, docs, etc. are part of feedback loop(s) you mentioned. More users => Users complain (What is confusing? What is missing? etc.) => things get fixed/cleaned up/improved => More users. Besides "performant" being multi-dimensional, the feedback loop is more of a "cyclic graph". :-) While I probably prefer Nim as much or more as @netbioserror, I am not too shocked by the mindshare capture. It seems to happen every 5..10 years or so in prog.langs.

While many of your points are not invalid, tech is also a highly hype-driven & fad-driven realm. In my experience, the more experience with this meta-feature that someone has, the more skeptical they are of the latest thing (more rounds of regret, etc.). Also, that feedback graph is not a pure good. Things can get too popular too quickly with near permanent consequences. ipv4 got popular so quickly that we are still mostly stuck on it 40 years later as ipv6 struggles for penetration. Whatever your favorite PL is, it may also grow features too fast.

You are welcome. Thanks are too rarely offered. :-)

You may also be interested in word stemming ( such as used by snowball stemmer in https://github.com/c-blake/nimsearch ) or other NLP techniques, but I don't know how internationalized/multi-lingual that stuff is, but conceptually you might want "series of stemmed words" to be the content fragments of interest.

Similarity scores have many applications. Weights on graph of cancelled downloads ranked by size might be one. :)

Of course, for your specific "truncation" problem, you might also be able to just do an edit distance against the much smaller filenames and compare data prefixes in files or use a SHA256 of a content-based first slice. ( There are edit distance algos in Nim in https://github.com/c-blake/cligen/blob/master/cligen/textUt.... as well as in https://github.com/c-blake/suggest ).

Or, you could do a little program like ndup/sh/ndup to create a "mirrored file tree" of such content-based slices then you could use any true duplicate-file finder (like https://github.com/c-blake/bu/blob/main/dups.nim) on the little signature system to identify duplicates and go from path suffixes in those clusters back to the main filesystem. Of course, a single KV store within one or two files would be more efficient than thousands of tiny files. There are many possibilities.

None of these lists ever seem to be as fleshed out, up to date, or well organized as https://github.com/awesome-selfhosted/awesome-selfhosted , though imo any more attention on the self hosted scene is awesome. We're now self hosting everything at my co-op, and it's a dream. Saves us money, provides learning opportunities, potentially is getting us work (managed hosting providers asking if we can be a devshop for their clients, for example), and lets us give back to the FOSS community as we uncover bugs.

We use:

* Matrix / Synapse for comms (slack alternative) (managed hosting through etke.cc)

There are a ton of resources about HW aspects of home labs for beginners but not so much for what to run on them and why. There are lists like https://github.com/awesome-selfhosted/awesome-selfhosted but they are confusing for absolute beginners like me. Are there any good SE project guides you know?

This[1] seems like a well maintained repo.

And thank you for the pointers, we'll try to get ourselves added here :)

I've always felt like FOSS as a philosophy has been tangled up in trying to participate effectively in capitalism, when that was never really the point, nor really very possible unless you're lucky, nor really worth it. The origin of FOSS as I understand it from reading books like "Hackers" is from people that were mad that access was being restricted to systems and code from people that really wanted to use these systems and code, and hack them, and learn from them. I recall that one of the things Stallman likes to brag about from that time is not related to FOSS at all, but instead successfully decrypting a bunch of passwords, emailing the decrypted passwords to people, and recommending they instead set the password to an empty string instead. It was about keeping access to the system Free as in Beer.

I suppose some have argued that FOSS represents a Public Commons in the way that fields and wells and physical markets used to, but none of those things survived capitalism, so I don't see why a technological commons should be expected to either.

For me I've been thinking lately that perhaps those interested in FOSS should instead consider how we can use FOSS to detach ourselves from needing to participate in global capitalism at all. Is there FOSS technology we can use to liberate people from things they need to spend money on right now? An example could be the Global Village Construction Set: https://www.opensourceecology.org/gvcs/ a set of open source designs for things like hydraulic motors or microcombines or steam engines that you can build on your own, usually not for cheap, but for far, far cheaper than you could buy from John Deere. Here's another cool project, some guy has just been building things like solar panels and basic circuit boards on his property from very base components for years: https://simplifier.neocities.org/

Some other FOSS liberation examples:

Combining a tool like Jellyfin with Sonarr, Radarr, and etc, can liberate people from their 5 different media subscriptions. Or at least they can still buy DVDs and put them on Jellyfin to have the convenience of streaming with the media library of their own choosing.

Deploying Matrix or another FOSS communication tool can let organizations have enterprise-level communication software without paying HUGE seat-based license fees to corporations like Slack.

In fact there's many ways to liberate yourself from paid SaaS in this list: https://github.com/awesome-selfhosted/awesome-selfhosted at my co-op we self-host and deploy all our services for this reason, it saves us a TON of money.

I don't have many other examples to mind because this is something I'm actively still researching. Friends in Venezuela though especially tell me how FOSS technology can liberate in ways I wouldn't expect here with my 64gb RAM machine with the latest processor, that I can easily replace components on on a whim. Such as how they can keep all their broken down machines pieced together from junkyards running pretty ok on various linux distros, and how they can sell creative work using free tools like gimp (no, really) or darktable. Like as not they'll just pirate software, though, but apparently FOSS often runs better on shitty hardware.

Anyway my long term plan is to find or build more and more things that let people just not spend money on things anymore. That could be by making it easier to not have to throw things away anymore, or building tools to replace proprietary ones, or, idk, other ways I haven't thought of.

Dashboard in what sense? Is this what you had in mind or no?
