        % id = "01H89RFHCQAQVXP6B2H0T8NNDS"

            + therefore I find boasting that my project is powered by a `$LANGUAGE` or a `$FRAMEWORK` unnecessary.

                + but if you really care that much, it's built with Rust, plain HTML5, plain CSS, and
                [Vanilla JS](http://vanilla-js.com/).

        % id = "01H89RFHCQRA4BBBWDC8K68BB0"
        - if you wanna browse the source code, feel free to [check it out on GitHub][def:treehouse/repo]

    % id = "01H89RFHCQFWC2FWBAE9PVNC08"
    - as I alluded to [here][branch:01H89RFHCQ3EAP0F6PRSEK7S1T], treehouse is built to decay gracefully
      as you take away the fancy parts.

        % id = "01H8V55APDMPF3WFTNTFSYBQRF"
        - you will be able to read it just fine without JavaScript, just that it'll be a little
          less pleasant.

            % id = "01H8V55APD1RSSRMDZ3CEE9S9C"
            - that's because the JS handles stuff like lazy loading of linked trees.

                % id = "01H8V55APDAPSR7R9M569GW4S7"
                - you may have seen a brief _"Loading…"_ text flash before your eyes as you opened this
                _about this_ branch - that's it downloading another tree and pasting it into this document

                    % id = "01H8V55APDS9BNC2TQ5S5VYC0G"
                    - when JS is unavailable we fall back to a plain old `<a>` link through a
                    `<noscript>` tag. if you have uBlock Origin, or any other JS blocker, you can try
                    that out yourself!

            % id = "01H8V55APD503DMXJD9JA2WJGS"
            - the JS also lets you select text in these `<details>` elements without them collapsing
              as you release the mouse button.

                % id = "01H8V55APD34KE6ED6MRTW34H6"
                - I have no clue why it is this way by default, but frankly it's like a 5 line
                  usability fix, so why not.

                    % id = "01H8V55APDR3VCEANQ6XVJP3X8"
                    - if you have accessibility concerns about this decision, please let me know.

            % id = "01H8V55APDFW5SPAKSQ04K5HRE"
            - it also saves your progress as you read. if you refresh the page, you'll notice you end up exactly where you left off!

            % id = "01H8V55APDNSXZMZJ2K1KW11KN"
            - but, there is one very crucial piece of JavaScript that makes this website tick, and your experience **will be degraded** if you disable it. that feature is linking to branches.

                % id = "01H8V55APDBG6AH2W3RNMX724X"
                - by default, if you link to an element by its id and it's contained within a `<details>`, the `<details>` will not expand. :ralsei_dead:

                % id = "01H8V55APDE0KSKKAS8RBRPYRM"
                - therefore there's a bit of JS to make that work, _and_ to tie that together with lazy loading.

        % id = "01H8V55APDTZSSYTY17SYZ6DGQ"
        - treehouse will not work *as* fine without CSS though - the `<details>` will look extremely
          janky, but the content should still be fully readable.

    % id = "01H8V55APDWN8TV31K4SXBTTWB"
    - myself, I'm writing this content in a bespoke format called `.tree`.

        % id = "01H8V55APDGX4EYV8W7ECXZ6FP"
        - the structure of `.tree` files is extremely minimal. there are only a few syntactic features to speak of.

        % id = "01H8V55APDR95HSV0TX7TK63AF"
        - here's a taste of `.tree`:

            % id = "01H8V55APD5686J8GTXP118V8E"
            - ```
            % id = "root"
            - this is a branch

                % id = "child"
                - this is a child branch

                + this is a branch that is collapsed

                    - and this is a child of that branch

                % content.link = "some-other-tree"
                - and this branch links to another tree
            ```

        % id = "01H8V55APDB49SPHPPMV2BCMW3"
        - the `.tree` format is line-based. that means the `%`, `-`, and `+` tokens are only
          interpreted when at the beginning of a line.

        % id = "01H8V55APD67W8FHEZK6E2A21K"
        - the basic unit of `.tree` is a branch. branches…

            % id = "01H8V55APDQ1KS7S313GK590GM"
            - …are located at a specific _indent level_

            % id = "01H8V55APDHNRFCGH9STD46J0F"
            - …may or may not have _attributes_ - that's what the percentage sign `%` begins

            % id = "01H8V55APDF9C7Y0QDYF3EBMMS"
            - …may or may not be expanded by default (this is the branch's _kind_) - that's what the minus `-` and plus `+` tokens do

        % id = "01H8V55APDJ6EYE4PR370JAT4W"
        - each branch is constructed in this order: optional attributes, kind, content

        % id = "01H8V55APDGT47G5DKZKTQ1S80"
        - and ends when another line beginning with `%`, `-`, or `+` is found.

        % id = "01H8V55APDQ3VYBBTTMNFTVNV4"
        - other than that, `.tree` assumes nothing about what format the branch attributes or content are encoded in.

            % id = "01H8V55APDCXPW8JPRYZHY9NXV"
            - I chose TOML and Markdown for their ease of use and flexibility, but the parser couldn't care less.

                % id = "01H8V55APDWDPSHNZX6QJFM8ZA"
                - …actually, that's a lie. see that code example above? Markdown code fences \`\`\` are handled specially to let embed `.tree` source code blocks within `.tree` files. that's all.

    % id = "01H8V55APDVQB6AD23Y6PZPPB8"
    - you may have noticed in that code example above that almost every branch has an `id` attribute.

        % id = "01H8V55APD4H5JT8NTYCCTN77G"
        - this is because I want every branch to be individually linkable and quotable.

            % id = "01H8V55APDPSZNP9AK7QRK62BG"
            - if you ever want to link anything I said in an argument online: hover over a branch, right-click that little _permalink_ icon that's on the right side of the screen, and _Copy Link_.

        % id = "01H8V55APDCZ0HY20GGXYE8D1G"
        - but manually coming up with ids for branches would be quite the nuisance.

            % id = "01H8V55APDXV0KRVEF9PTA72J7"
            - that's why with the power of Tools Programming™, I built a tool that fills out all the ids for me.

                % id = "01H8V55APD8VG7WE6JX5JBDJEC"
                - I chose [ulids](https://github.com/ulid/spec) for generated ids, for a few reasons:

                    % id = "01H8V55APD2J58ENT1T0JRJ7H6"
                    - they're guaranteed to be unique, so I can be sure no two branches end up having the same id

                        % id = "01H8V55APDGV6PKJKZ16CJ1YXY"
                        - which is precisely what lets me pull the trick where I embed one tree within another, and you just dig into `index.html`.

                    % id = "01H8V55APD1CYZD8GE3AK87QK2"
                    - they embed a timestamp, which I can use to display the date/time when a branch was written, because I generally `fix` branches right after writing

                        % id = "01H8V55APDFXW5A5J85HJQP17C"
                        - as well as highlight branches which were added since your last visit

                        % id = "01H8V55APDPZK4C8H5TTHTHH7J"
                        - not that either of these features are implemented as of writing this (2023-08-20)

                    % id = "01H8V55APDXB9AXTAGAE9TNQRB"
                    - they're much more compact than [uuids](https://en.wikipedia.org/wiki/Uuid)

                        % id = "01H8V55APDZE5AE92GDM2TH2EF"
                        - which use 32 hexadecimal digits separated unevenly by 4 dashes, giving you 36 characters.

                            % id = "01H8V55APDS478E3ED5CRVT6RE"
                            - who even remembers how many digits there are between each dash? I know I don't.

                        % id = "01H8V55APDXP1D0MHGN2DXBT16"
                        - ulids on the other hand are 26 digits encoded with [Crockford's base32](https://www.crockford.com/base32.html)

                            % id = "01H8V55APD79QTC2NFC6X7S3W4"
                            - which is cool because it's much denser while avoiding ambiguous characters - `0`, `O`, and `o` are all interpreted as `0` (zero).

    % id = "01H8V55APDXT064G9PA78JW0CM"
    - noticed how fast the treehouse restores your state? there's basically no delay.

        % id = "01H8V55APDGS626M5Y6DDAS9ZE"
        - this is because it restores your state _as it's loading in_, by using [Web Components](https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_custom_elements).

            % id = "01H8V55APD73AG65NP2VGX6169"
            - despite many people calling that API extremely low-level, I beg to differ. it's actually pretty easy and pleasant to use.

            % id = "01H8V55APDDHYNRZXQDEG0A242"
            - most importantly it lets me enhance vanilla `<li>` elements with custom behavior executed on load, which I use to restore your reading progress as the page is loading in.

        % id = "01H8V55APD4V54M2EKQKQ4GNP8"
        - linked branches also use Web Components by the way.

    % id = "01H8V55APDKY0HYEJM2C1CJHEG"
    - while not strictly a technical topic, I'd like to shout out [Recursive](https://recursive.design) for being an awesome font :ralsei_love:

        % id = "01H8V55APD88JCQBQ4SHVCYR97"
        - (not to be confused with [Font Awesome](https://fontawesome.com/), which I do not use here. icon designs are my own.)

        % id = "01H8V55APD0S00ACN0YY7Y9MSW"
        - being a variable font, I can tweak the text's look and feel on many different axes.

            % id = "01H8V55APDRG88JRV74MMDTV4J"
            - the one that I wanted to shout out in particular is `CASL`, which lets me make it look a lot more happy and playful.

                % id = "01H8V55APDMP5FE9ZCMRACH18W"
                + almost like Comic Sans, but without all the stigma.

                    % id = "01H8V55APDPGMD33J4M3SJ2QKP"
                    - I actually considered using [Comic Neue](https://comicneue.com/) as the font on this website, but ultimately chose Recursive.

                        - Comic Neue and not the Real™ Comic Sans MS because it's licensed under the SIL Open Font License, which means I could redistribute it on my website.

                            - not everyone runs Windows or macOS, so just assuming the reader has Comic Sans installed isn't ideal.

            - ~~in particular the variant on my website is 100% casual (`CASL`), and -2.0 slanted (`slnt`).~~

                + that little bit of slant makes it look just a little more like handwriting.

                    - I actually thought of handwriting all the text in the treehouse, but ultimately thought it would be too much work. and a technical challenge too.

                        - how to make it scalable (as in, how to keep it smooth when you zoom in?)

                        - how to make it scalable (as in, my hand really fucking hurts from writing this much, and I *really* do not wanna go back to the times of writing school essays please?)

                        - how to make it scalable (as in, how to distribute this many images to the user without tanking their internet connection?)

                        - not to mention I'd have to handwrite a lot of text, and *then* either use OCR or type it all out again for accessibility. yeah, no thanks methinks.

                - UPDATE: not slanted anymore. `slnt` is 0.
