origami | origami project provides Monadic folds | Functional Programming library

Referring to this post, i'm trying to adapt the animations to landscape mode. Basically what i want is to rotate all layers of -90° (90° clockwise) and the animations to run horizontally instead of vertically. The author didn't bother to explain the logic under the hood, there are a dozen paper folding libraries in obj-c which are all based on the same architecture, so apparently this is the way to go for folding.

EDIT: To further clarify what i want to achieve, here you can look at three snapshots (starting point, halftime and ending point) of the animations i want. In the question from the link up above the animation collapses from bottom to top, while i want it to collapse from left to right.

Down below you can take a look at the the original project a bit tweaked:

• i changed the gray bottomSleeve layer final angle value, as well as the red and blue ones angle;
• i paused the animations on initialization by setting the perspectiveLayer speed equal to 0 and added a slider, the slider value is then set equal to the perspectiveLayer timeOffset so that you can interactively run each frame of the animations by sliding. When the touch event on the slider ends, the animations are then resumed from the frame relative to the current timeOffset to the final value.
• i changed all the model layers values before running each animation added to the relative presentation layer using CATransaction. Also, on completion the perspectiveLayer speed is set to 0 again.
• for a better visual understanding, i set the perspectiveLayer backgroundColor equal to cyan.

Just to point it out, there are two main functions:

1. setupLayers(), called in viewDidLoad() is responsible of setting up the layers positions and anchor points, as well as adding them as sublayers to the mainView layer.
2. animate(), called recursively in setupLayers(), responsible of adding the animations. Here i also set the model layers values to the related animations final value before adding them.

Just copy, paste it and run:

I want to show icons and text on my Android TabbedPage tabs in my Xamarin application, and I want them to be FontAwesome glyphs rather than png files.

My TabbedPage is defined in code, and I originally set the IconImageSource for the child pages in their constructors. In iOS, that's all I seem to need to do for png files to show up, but in Android that didn't work (though I think it should have, no idea why it didn't) so I seem to need a custom renderer even for the pngs. This renderer works for pngs if I add an "IconName" field to each of my ContentPage classes and set its value to the name of the png file (without the .png extension):

how do i go about doing this? Assuming I have a .txt file with that looks like something in the first codeblock below, keeping in mind 1 name might be in the .txt file more than one time so for example Jack's hobbies are crafting as well as skateboarding.

I want to compute accuracy using sets logic. I'll explain with an example:

For these two dictionnaries:

I got a grammar supporting this:
AND, OR, NOT, ( and ), ", '

Few samples of things I need to be able parse:

• a1 OR a2
• a1 a2 (same as above)
• a1 AND a2
• "a1" AND 'a2'
• a1 OR a2 NOT a3
• a1 a2 OR "a3" NOT(a1 AND a2 'a6')

Considering a1, a2, and so on are real user input that could include almost anything like:

• 123
• Tesla-S
• origami

The problem I got, is when one of those word are without quotes, and starts with some reserved keyword, for example:

• origami
• andromede

In this case, this parser consider:

• or keyword + igami text
• and keyword + romede text

That's the problem I got.

I've tried for two days various solutions, found on stackoverflow (and official doc):

• Pegjs: Don't allow reserved keywords as a variable name

(and many other) trying to find a solution with those constraint:

• it's not guarantee that there is space before/after keyword, for example "a1 AND(a2 OR a3)" is valid (no space between "AND" and "("), so is "(a1 AND a2)OR a3" => a keyword could have before/after it, a space and/or "("/")" (but when I try this I break the parenthesis rule)
• a word is NOT a word only if it's part of the reserved section: "AND"i / "OR"i / "NOT"i / "(" / ")" / "'" / '"' / " " => any of those are not a word, anything else is, like ando is a word, not a keyword.

Here is the code I came up with:

Has anyone found a way to have more complex pane layouts in Visual Studio Code, like those supported by Origami for Sublime? Layouts beyond splitting on the same axis are something that I really miss from Sublime.

I'm writing a program to optimize a packing problem using Robert Lang's algorithm from his webpage: https://langorigami.com/wp-content/uploads/2015/09/ODS1e_Algorithms.pdf

This is used to design origami models and it's a problem from circle packing with constraints and different radius.

I have created an example with 5 nodes, where 4 of them are terminal. Looking at these definitions included in the previous algorithm, I want to work with the Scale Optimization (A.3).

According to the notation, in my example I have:
