Make constraints useful

Recently, I came re-listened to a podcast episode where they discussed about constraints.

Everyone thinks that constraints are bad.

But having some constraints may be good.

Rust Script

After my previous post I came across other ways to “quickly test rust code” Obvious being rust-script It is easy to install via cargo install rust-script (But I had it already installed. I think Espanso installed it, but not too sure) This may be better than rustc because one can define the dependencies in the “script” itself, like : #!/usr/bin/env rust-script //! Dependencies can be specified in the script file itself as follows: //!

Rust: When rustc Beats Cargo for quick trial code

Recently, I needed to test try some functionality (of getting user’s home directory) ¹

Setting up a throw away project via cargo new is certainly possible but seemed overkill.

Polywork Shutting Down

This morning, I got an email notification that polywork.com shutting down.

Polywork was a good idea.

I never updated it regularly because I was worried about such thing (it going away) But I liked the idea of putting regular “updates” and I started this microblog.

Rust: How to print Command Output

I was going thru struct Command in std::process ¹

Obviously, I tried the very first code snippet in the rust playground. There is a very convinient ▸ to run the sample code.

The code ran without any errors.

But no output 🤔

Finally got Auto Complete working in Helix

I have been using Helix as an editor, not as an IDE. One of the USP of Helix is LSP support out of the box

Recently, I’ve been programming in rust.

Helix is also written in rust.

So I think it is natural that they would support rust LSP rust-analyzer and it does.

But I wasn’t getting auto completions 😞

Rust: Unit tests in a separate file

In rust, tests are written in the same file as the code. But I want to have the tests in a separate file. Conventionally, only the integration tests are written in files under tests folder. 1 I just wanted to have the unit tests in a separate file. So I created a file src/my_tests.rs and moved all the tests there. But cargo test kept saying running 0 tests Turns out, I’m not the only one.

Updated the README for the Theme Repo

It has been little over 2 years since I forked and updated jnjosh’s internet-weblog theme While I made several changes to my fork, I never updated the README. till now that is. During last few days, I updated the README to match my fork. These are minor changes, and majority of the README is still from the original (For the things that have not changed) If you are curious, have a look 😄
