litpro-svelte

This is a literate-programming setup that is intended to work with svelte a little better.

Really, this is designed mostly with sapper in mind (exporting to a static site form is my mo).

Specifically, it does:

• Latex math display using Katex
• Shorthand element tagging using indents like pugjs
• Some shorthand css properties like TailwindCSS does (but not as classes)

Katex

Command: katex

Required for usage: katex.svelte, katex files in main html

Using $ $ and $$ $$, we can write latex expressions in between in a text. This, when piped through the command katex, will translate this into a form that the Katex.svelte component can work. You need to import Katex.svelte for that to work. It is designed to have the Katex support files in the main html file.

Pug-lite

Command: psv
[psv short for pug-svelte].

Requires nothing else, direct substitution.

Pug-lite. I like the idea of writing a tag and using indents, as well as # for id and . for classes. The rest of the pug syntax is dropped as it is largely not needed in the context of svelte which does its own kind of markup. For a tag to be recognized as such, use a . even if it there is no class. If the first word does have a period or hash, then it is assumed to be plain text. Multiple periods or hashes in a row will be reduced by one as a way of escaping (only relevant after the first word). Any other attributes for the element can be written as usual directly after the class hash stuff. Hash id should be in order.

element#id.class1.class2 att="whatever" {svelte}"

If element is missing, then it becomes a div if there is a hash and a span if just a class.

If a line needs to extend to the next line for attributes or whatever, then a vertical bar should be the last character.

Indents are used for nesting.

Tailwindish

Command: twcss

Requires nothing else, it directly writes down the css syntax.

This is inspired by TailwindCSS, taking from it the idea of some restricted uses and shorthand notations. It differs quite a bit, in particular, not using classes. Given that svelte has the styles scoped to the element, using the structure of the component seems fine.

Spacing commands are p for padding, m for margin, with x,y,l,r,t,b,a following them standing for left+right, top+bottom, left, right, top, bottom, and all. There is also gp, gapx, gapy for gap, column-gap, row-gap. The spacing is then of the form px 0-6, 8, 10, 12, 16, 20, 24, 32, 40, 48, 56, 64.

For colors, we use numbers 0-9 for severity (except black, white which is just one color and also transparent). Colors are gray, cool-gray, red, orange, yellow, green, teal, blue, indigo, purple, pink. From tailwind.

The color types can be used with bg (background-color), liner (border-color), and text (color)

We have single static words just for a little briefer:

    static : 'position: static',
    fixed : "position: fixed",    
    absolute : "position: absolute",
    relative : "position: relative",    
    sticky : "position: sticky".
    delete : 'display:none',
    hide: 'visibility: hidden',
    block : 'display:block',
    inline : 'display:inline',
    inblock : 'display:inline-block',
    flex: 'display:flex',
    flexinline : 'display:inline-flex',
    grid : 'display:grid',
    gridinline : 'display:inline-grid',

We also have border radius (br: brb, brt, brl, brr, bra) and border width (bw: bwx, bwy, bwt, bwl, bwr, bwb, bwa). The widths have width 0, 1, 2, 4, 8 (straight px) while the radii have zr, sm, nm, md, lg, fl for zero, small, normal, medium, large, full).

JSXGraph

No Command.

Requires Jsxgraph.svelte

There is no translation layer here, but this produces the svelte-component for having it. Properties of width and height on the element.
