Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Qsv: Efficient CSV CLI Toolkit
Thanks for the detailed feedback @snidane!
As maintainer of qsv, here's my reply:
- Given qsv's rapid release cycle (173 releases over three years), the auto-update check is essential at the moment. Once we reach 1.0, I'll turn it off. For now, given your feedback, I've only made it check 10% of the time.
- Pivot is in the backlog and I'll be sure to add unpivot when I implement it. (https://github.com/jqnatividad/qsv/issues/799)
- I'll add a dedicated summing command with the group by (-by) and window by (-over) capability (https://github.com/jqnatividad/qsv/issues/1514). Do note that `stats` has basic sum as @ezequiel-garzon pointed out.
- With the `enum` command, qsv can achieve what you proposed with `laminate`. E.g. qsv enum --new-column newcol --constant newconstant mydata.csv --output laminated-data.csv
- With the cat rowskey command, qsv can already concatenate files with mismatched headers.
- other file formats. qsv supports parquet, csv, tsv, excel, ods, datapackage, sqlite and more (see https://github.com/jqnatividad/qsv/tree/master#file-formats). Fixed-format though is not supported yet and quite interesting, and have added it to the backlog (https://github.com/jqnatividad/qsv/issues/1515)
- as to "enable embedding outputs of commands", qsv is composable by design, so you can use standard stdin/stdout redirection/piping techniques to have it work with other CLI tools like jq, awk, etc.
Finally, just released v0.120.0 that already incorporates the less aggressive self-update check. https://github.com/jqnatividad/qsv/releases/tag/0.120.0

Why my favourite API is a zipfile on the European Central Bank's website
qsv [1] also has a sqlp command which lets you run Polars SQL queries (even on multiple files). Here I'll send the csv data from stdin (represented by -) and then (optionally) pipe the output to the table command for formatting. The shape of the result is also printed to stderr (the (4, 2) below).

Do Rust and Lua work well together?
It works quite well IMHO. Using the mlua crate, I’ve managed to integrate Luau as a very powerful data-wrangling DSL for qsv (https://github.com/jqnatividad/qsv)

How manipulate this CSV in Python?
Maybe this might be better done using this? https://github.com/jqnatividad/qsv

https://github.com/jqnatividad/qsv is another option.

Do Rust and Lua work well together?
I'm not a specialist about text based multiplayer game, but from what I saw on Wikipedia it seem doable to do it with Rust and Bevy. On top of that you can add a layer of LUA with https://github.com/khvzak/mlua (or write your own bindings and sandbox later).

Introducing Petrichor64 - a rust and wgpu built game engine/fantasy console with lua game logic
mlua can run on emscripten target with Luau backend -> https://github.com/khvzak/mlua/issues/23
- I was searching for embedded lanaguages in Rust and I found out I can use deno https://deno.land/[email protected]/embedding_deno which is amazing has anyone tried it ?

Repos using rlua/mlua
You can also look at the "dependents" section on crates.io https://crates.io/crates/mlua/reverse_dependencies and github https://github.com/khvzak/mlua/network/dependents

is rlua-async supports mutli-threading?
I know mlua does support Async. I also prefer it over rlua

Rust and Lua api
Note rlua doesn't allow you to create native modules with it and has largely been superseded by https://github.com/khvzak/mlua since it's more maintained, has native module support and stuff like Luau and async/await.

Lua: Good, Bad, and Ugly Parts
I believe mlua [0] is the recommended Lua Rust binding now.

Dash.nvim v0.8.0 now supports Telescope, fzf-lua, and Snap fuzzy finders!
This is achieved through a backend/client architecture -- all core functionality (getting query results, opening selected item, search engine fallback, etc.) is implemented in a "backend" module, which is a Rust library exposed as a Lua module via mlua. The results returned by the backend then get fed into your fuzzy-finder of choice through thin clients, or "providers".
