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.

This Week in Rust #497
The eRFC was intentionally light on details so the Pre-RFC / IRLO thread and the demo best reflect what we hope to accomplish which are pretty detailed as-is.

Rust went from side project to world’s fastest growing language
> A) is easy to write one off scripts that do a job fast, with minimal thinking and effort. I am thinking of Python and Ruby. For me I can write code with high velocity in these languages.
Once I wrap up some other projects, I plan to explore this space a little bit within Rust.
imo the biggest bang for the buck is just having good `#!` support. Probably mid-year I expect to have a Pre-RFC up for single-file cargo packages. See https://github.com/epage/cargo-script-mvs/discussions/15.
A bigger effort is a batteries included, non-zero cost stdlib. I've started writing up my thoughts at https://github.com/ergo-rs/ergo.
For more background on why I think these are important, see https://epage.github.io/blog/2021/09/learning-rust/.
Would love feedback on these ideas and other ways to make Rust easy to use without sacrificing what makes Rust it is.

Rust as bash scripting replacement?
This is something I'm interested. Every time I write a bash or Python script, I think "why didn't I do this in Rust?". The first barrier is in the same line as your thoughts which is why I've been investigating the various cargo-script spin-offs and working towards an MVP for a Pre-RFC.

Val on Programming: What makes a good REPL?
Something I've been thinking a lot about for Rust is what can and should a REPL experience be for a compiled language (ie what are reasonable compromises).
There seem to be two repls that haven't gotten much traction:
- https://github.com/google/evcxr/blob/main/evcxr_repl/README....
- https://github.com/sigmaSd/IRust
There have been little and big nits that have held me back from wanting to push these further, including
- Bad defaults (having to opt-in to panic handling)
- Command syntax feeling out of place and likely not beginner friendly
- Limits on variable preservation
- Lack of introspection (at least irust as `:type`)
So far I've been punting on wanting to improve this area by instead focusing on polishing up a rust script solution in the hopes of getting it merged: https://github.com/epage/cargo-script-mvs

Quick Tip: You don't need to create a new cargo project if you want to test if something works in rust
rust-script is the most up-to-date version I could find. See https://github.com/epage/cargo-script-mvs/discussions/15

Creating an Easy Mode for Rust
cargo-script has been forked or reimplemented several times.

clap with Ed Page :: Rustacean Station
cargo-script: I've done some initial analysis and recorded my thoughts on what cargo-script in Rust should look like. If people are interested in this or other individual / company on-boarding improvements, I'd love to talk!
-
When not to use Rust?
Fully agree with this though I also feel there is room for experimentation and improvement in this area. I've previously blogged on this and have started researching cargo-script. Hopefully later I'll get to my standard-adjacent library.

Selling cheap rust cheats and scrips
Accept BTC, all credit card * $1 .unwrap() - wallhack through Err * $2 .ok() - invisibility cheat for unused Result warning * $5 .unwrap_unchecked() - advanced wallhack, never fall out of map from panic For script console, just $10.
- Why is Rust always advertised as system programming not general purpose programming?

You can also use cargo script. After installing it you can just do

Announcement: xshell 0.2.0
I think there are some projects in this area, eg, https://github.com/DanielKeep/cargo-script. For my personal scripts, I have a single Cargo.toml for a busy-box style multiplexed binary: https://github.com/matklad/config/blob/f0259ca8a3755f2e62a3bf472c2514fd6cb891ff/tool/src/main.rs#L16.

How do you share your code ?
O seems that this does already exist: https://github.com/DanielKeep/cargo-script

Shell Scripting in Rust
You don't have to set up a project if you use cargo-script

Is there any way to compile and run Rust from an input stream?
Take a look at cargo script. That should/could do what you want
- Run Rust source code like a script (Linux)

Rust for simple tasks
when I first started using rust, I knew python a lot better so I would write scripts with python. at this point though, I write a lot more rust than python these days, so I'll write pretty much everything with rust. cargo-script is a useful tool for this, as well as the self-compiling script: https://neosmart.net/blog/2020/self-compiling-rust-code/
-
Correct way to do "micro projects"?
Another option is cargo-script, which lets you run self contained rust files.
What are some alternatives?
rust-script - Run Rust files and expressions as scripts without any setup or compilation step.
gcpp - Experimental deferred and unordered destruction library for C++
cargo-do - allows you to run multiple cargo commands in a row
evcxr
cargo-watch - Watches over your Cargo project's source.
IRust - Cross Platform Rust Repl
cargo-outdated - A cargo subcommand for displaying when Rust dependencies are out of date
team - CLI working group
cargo-edit - A utility for managing cargo dependencies from the command line.
runner - Tool for running Rust snippets
