@Laurent, communicating with Firebase through ports using a web worker seems a very interesting topic. Is there any post/article/repo where we can learn more about this?

Nicolas Hafner: Kickstarting the Final Stretch - February Kandria Update

via Planet Lisp by on Mon, 07 Feb 2022 09:50:03 GMT

January's already done with, and there's a lot of stuff brewing behind the scenes. One of those things I can already announce now, and I'm very excited to do so!

Kickstarter!

There will be a Kickstarter for Kandria in June! We're currently still preparing for it and working out all the details. We'll be sure to let you know once we have a "coming soon" page for it up and running.

The Kickstarter will come combined with a new demo on Steam Next Fest, as well as a brand new trailer. I hope you look forward to it, I know I sure am!

Horizontal Slice

The Horizontal slice is moving along according to schedule. All the areas for the main game are now playable, and all of the story content is almost complete. That still leaves a ton of work to finish the game though, don't get me wrong. We need to playtest it all to make sure the traversal feels right, that the pacing of the game works well, and that the progression is satisfying and fun to engage with. Then we need to polish up all the areas' visuals and make them really pop. That, especially, takes a lot of time on its own already.

We also need to add some side quests and deck out the areas with secrets and things to discover and investigate, to feed into that nice loop of one distraction leading to another that open world games tend to do well. And finally there'll be a long stretch of smoothing out corners, playtesting, fixing bugs, adding small bits, and localising the game.

To be honest, thinking about all the things we still have to do is making my head spin, but so far we've, miraculously, been able to stick very close to our planned schedules, so it seems like we're moving ahead at a good pace.

The bottom line

Okey, let's look at the roadmap from, uh, two months ago since I didn't include one in the yearly update.

• Implement RPG mechanics for levelling and upgrades

• Explore platforming items and mechanics

• Practise platforming level design

• Draft out region 2 main quest line levels and story

• Draft out region 3 main quest line levels and story

• Complete the horizontal slice

• Polish up the lower part of region 1

• Implement new enemy types

• Complete the new demo

• Create a new trailer and Kickstarter video

We've already started work on the new demo, which we need to have done at least a month before the Kickstarter launches in June. So much to do!

Custom slider for elm-ui using SVG

Thanks. If I had made the control myself, it would make perfect sense. But now I have only slapped an illustration on top of an elm-ui control.

Discovered a Compiler Message Issue...Now What?

Joe Marshall: Imperative vs. Declarative

via Planet Lisp by on Sat, 05 Feb 2022 13:49:00 GMT

I saw this recently:

    token = request.headers.get('Authorization')
    token = token.split(' ')[1]

From an imperative programming point of view, there is nothing wrong with this. We assign to the token variable the contents of the Authorization header, then we assign to the token variable the second substring after splitting along spaces. After executing these two statements, token will contain the desired value.

From a declarative programming point of view, this is terrible. The first statement binds the name token to the Authorization header, but the second statement contradicts the first by changing the binding of token to mean something else. Thinking declaratively, we'd much prefer either

    header = request.headers.get('Authorization')
    token = header.split(' ')[1]

or

    token = request.headers.get('Authorization').split(' ')[1]

The first option avoids the contradition and reassignment by simply using a separate variable. The item we get from request.headers isn't a token, it's a header, so we should name the variable appropriately. The token is a separate quantity that we compute from the header and the code directly reflects that.

The second option just avoids the intermediate variable and lets the compiler choose how to deal with it. Again, there is no contradiction or reassignment, token receives its final value when it is bound.

The problem is this: in the original pair of statements, the first statement

    token = request.headers.get('Authorization')

while imperatively a valid command, is declaratively a lie. It says that token is literally the Authorization header, but it isn't. The second statement patches things up by fixing the value of token to be what it ought. It seems poor practice to deliberately put these sorts of lies in our programs. We can make the first statement true by simply renaming the variable.

Debounce as an effect

via Elm - Latest posts by @romper stomper on Sat, 05 Feb 2022 15:40:34 GMT

There are several topics here and as well as designed packages related to the problem of debouncing/throttling messages. So we all understand what we mean by debouncing: if we have consequent events with intervals between them less than a certain time value, we want to consume only the last ignoring the rest.

So the question: why is would be not a good idea to have debounced/throttling capabilities made available as effects for example exposed through the Time module? The question is not a proposal, but it means like it sounds, what would be architecturally/ideologically wrong to assume/do such a thing?

This is interesting if this means that we could have in-house packages.
