warpd VS zsv

I also enjoyed using https://github.com/rvaiya/warpd on my mac. But was hit with few bugs, where the pointer used to get stuck. Had to keep restarting. But still a nice program to ditch mouse.

for something similar that works with anything even beyond your browser there's warpd. I haven't used it I just know it exists. If you're into custom keyboards QMK can send mouse movements from keypresses too.

So I am trying to compile warpd, i followed and installed the dependencies, but when I make, it outputs wayland-client.h not found. Fair enough, I installed geckolinux TW Plasma, NVIDIA working fine, X11 session. I used "zypper se", it showed wayland is installed but nevermind; in the docs they have said that you can 'Set options' to only compile X11 binary. I want only that but I am just racking my brain where to insert 'DISABLE_WAYLAND' option. I know its a most basic and obvious setting but i come from arch where i fully relied on AUR for building so i zero compiling knowledge. I tried RTFM but idk what I have to find. I would be helpful if someone helps me here

Hey there! You should definitely check out warpd. It's a modal keyboard-driven pointer manipulation program that can help you control the pointer on your screen using just your keyboard.

I think you're maybe thinking of warpd? https://github.com/rvaiya/warpd

warpd avoided me spending a lot of time going from the keyboard to the mouse,for simple point and clicks. Honestly it is super useful.

Maybe you'd find warpd intersting.

I'd like to minimize my need for a mouse but there are some tasks which are just so much simpler with a cursor. I do have some mouse keys setup with Karabiner so that holding "k" and pressing esdf moves the cursor, but I've found this difficult to get used to. I have a few different keys to modify the speed, but it just feels way too convoluted and effortful to to control the cursor this way.

I've also tried warpd [1] but had some issues with it that turned me off to it.

Curious to know if anyone here has had success with something else

I actually wrote this after seeing https://github.com/rvaiya/warpd on HackerNews and saw multiple people lament that they'd like to be able to use that for Windows. You should definitely check that out!

If it could be tabular in nature, maybe convert to sqlite3 so you can make use of indexing, or CSV to make use of high-performance tools like xsv or zsv (the latter of which I'm an author).

https://github.com/liquidaty/zsv/blob/main/docs/csv_json_sql...

Parsing CSV doesn't have to be slow if you use something like xsv or zsv (https://github.com/liquidaty/zsv) (disclaimer: I'm an author). The speed of CSV parsers is fast enough that unless you are doing something ultra-trivial such as "count rows", your bottleneck will be elsewhere.

The benefits of CSV are:

- human readable

- does not need to be typed (sometimes, data in the raw such as date-formatted data is not amenable to typing without introducing a pre-processing layer that gets you further from the original data)

- accessible to anyone: you don't need to be a data person to dbl-click and open in Excel or similar

The main drawback is that if your data is already typed, CSV does not communicate what the type is. You can alleviate this through various approaches such as is described at https://github.com/liquidaty/zsv/blob/main/docs/csv_json_sql..., though I wouldn't disagree that if you can be assured that your starting data conforms to non-text data types, there are probably better formats than CSV.

The main benefit of Arrow, IMHO, is less as a format for transmitting / communicating but rather as a format for data at rest, that would benefit from having higher performance column-based read and compression

I wanted so much to use csvkit and all the features it had, but its horrendous performance made it unscalable and therefore the more I used it, the more technical debt I accumulated.

This was one of the reasons I wrote zsv (https://github.com/liquidaty/zsv). Maybe csvkit could incorporate the zsv engine and we could get the best of both worlds?

Examples (using majestic million csv):

```

This of course assumes that each line is a single record, so you'll need some preprocessing if your CSV might contain embedded line-ends. For the preprocessing, you can use something like the `2tsv` command of https://github.com/liquidaty/zsv (disclaimer: I'm its author), which converts CSV to TSV and replaces newline with \n.

You can also use something like `xsv split` (see https://lib.rs/crates/xsv) which frankly is probably your best option as of today (though zsv will be getting its own shard command soon)

Am looking for one-time help creating documentation (e.g. man pages, tutorials) for open source project (e.g. https://github.com/liquidaty/zsv) as well as product documentation for commercial products, but not enough need for a full-time job. Requires familiarity with, for lack of better term, data janitorial work, and preferably with methods of auto-generating documentation. Any suggestions as to forums or other ways to find folks who might fit the bill for ad-hoc or part-time work of this nature?

Nice work. I am a fan of tools like this and look forward to giving this a try.

However, in my first attempted query (version 3.1.6 on MacOS), I ran into significant performance limitations and more importantly, it did not give correct output.

In particular, running on a narrow table with 1mm rows (the same one used in the xsv examples) using the command "select country, count() from worldcitiespop_mil.csv group by country" takes 12 seconds just to get an incorrect error 'no such column: country'.

using sqlite3, it takes two seconds or so to load, and less than a second to run, and gives me the correct result.

Using https://github.com/liquidaty/zsv (disclaimer, I'm one of its authors), I get the correct results in 0.95 seconds with the one-liner `zsv sql 'select country, count() from data group by country' worldcitiespop_mil.csv`.

I look forward to trying it again sometime soon

All this banter arguing over CSV, JSON, sqlite seems unnecessary when you can just push format X through a pipe and get whichever format Y you want back out: https://github.com/liquidaty/zsv/blob/main/docs/csv_json_sql...
