I wrote a little command-line interface for sending a http request and
getting the response.
I call the package url-cli, and the command itself is url.
It has sub-commands for the different http methods.
If you have a rust toolchain installed, you can get it by cargo install. I haven’t made any binary packages yet.

Again, after almost four months since the last release, it is time to announce rsass 0.27.0. There is a bunch of breaking changes and a bunch of improvements.
This time, one change may seem drastic: The rsass crate no longer
contains the command-line program rsass.
Instead, that is now provided by a separate rsass-cli crate.
So you no longer have to enable a “commandline” feature, instead you can
install the command line interface with:

There is also a new rsass-macros crate. Read on into the Macros section for that.

More than three months after the last release, is is now the time to announce rsass 0.26.0. There is a bunch of breaking changes and a bunch of improvements. The changelog has the whole (too long) list.
But this time, some of the changes may go a bit deeper. As usual, the breaking changes is breaking mainly to users who in some way modify the global context from rust code, maybe by providing their own builtin functions or maybe just by inserting a global variable.
Also this time, there is an improved way of calling ructe from a cargo
build.rs program, see the Cargo section below.

Sometimes I want to embed a video on my site. Most of the videos I want to embed are on youtube. Klicking “share” on a video and choosing embed, I get a bunch of html code I can copy into a post. Something like this, for example:

I går fick jag hålla en gästföreläsning om programspråket Rust på kursen programmeringsparadigm på KTH. Jag är inte en van föreläsare (och helt klart inte på-minuten-deltagare), så det är ganska mycket tvekan och stakningar i början, men jag lämnar i alla fall inte rummet förrän efter föreläsningen, och så småningom kommer jag igång lite.

Jag har skrivit ny blogmjukvara igen!
Den förra hette r5, som i Rasmus (utan 5
bokstäver). Den nya är skriven i Rust (källkodsfilerna heter .rs),
så det kändes naturligt att kalla den r4s,
också som i Rasmus (men utan 4 bokstäver 😎).
Nu får vi se om ett nytt kul blogprogram får mig att skriva fler blogposter.

When doing a web application server, one of the first things to decide is which “web application framework” or “request handler library” to use. In Rust, there are more alternatives for that question than in most programming languages, and anyone who has ported some code from tomcat jsp to play framework or from flask to django may dread making the wrong choice. On the other hand, Rust being very strict on static typing makes it very easy to do major refactorings, and I have switched existing projects from iron to nickel to gotham to warp myself without too big problems.
Posted 2019-07-26 19:12. Tagged rust, fractal, wasm, demo, javascript.
I like to write programs to render fractals, and especially Julia set fractals. I also like the Rust programming language. Among other advantages it happens to be great for compiling to wasm, the new format for executing code in a web browser. And I like to code stuff for the webb. So how come I haven’t written a wasm Julia renderer in Rust yet?
Well, now I have.

There is A Call for Community Blog posts over at the Rust Programming Language Blog. This is my entry, briefly describing my hopes and expectations for Rust, it’s eco-system and my own participation in 2019.

Jag har inte lagt upp någon propagandacykling här på bloggen på ganska länge. Naturligtvis cyklar jag fortfarande till jobbet de flesta av de dagar jag inte jobbar hemifrån, och jag brukar ta en bild och lägga ut på twitter.
Men jag har ett projekt för att organisera mitt bildarkiv på gång också.
Det har kommit så långt att det är smidigare att lägga upp mina bilder där än här. Så vill du se mina samlade cykelbilder så finns de där!
Men jag får väl inkludera tre ganska färska bilder här också.

I mainly do “server-based” web service development. The server sends html, css, images, and javascript to the browser. The javascript implements progressive enhancement for the content, but the site should be usable and as nice as possible even with javascript disabled. So while I certainly do RESTful json API:s, I also do server-side html templateing, css (and scss) minification, etc. I think Rust has great potential here, partly because of optimization and execution speed, but mainly because the type safety and fearless concurrency make it easy to actually get things right and avoid unpleasant surprises at runtime.

When developing web applications, it is often useful to have a template system. Something that lets you write generic versions of web pages, that the application can fill with the specific content for each page it should show.
There exists lots of “languages” to write such templates, such as mustache, jinja2, and play 2 scala templates (twirl). Most fits very well with a dynamic language, where you can get properties from an object, or even call a method, by its name in a plain string. In a statically compiled language, the actual names of fields and methods are not relevant, and generally not present, after compilation. This makes a “dynamic” template language a hard match for a compiling language such as rust. So why not try to create a better match?
