# details
|
||||
|
||||
now i am not a huge fan of putting christianity into my conlang, which
|
||||
is hopefully understandable. but having a midwinter festival sounds
|
||||
cute. the days are finally getting longer! you made it through the worst
|
||||
part! and so on. so that's what this is. i think it probably takes place
|
||||
the day after the solstice, but with several days of festivities, so
|
||||
that there is still a little overlap with the *other* winter holiday.
|
||||
it's still appropriate to say it today.

|

- in between [![](chrismas/igisim.svg "igisim"){.scr
|

.laantas}[igisim]{.text}]{.lang} (winter) and
|
||||
[![](chrismas/šangubam.svg "šangubam"){.scr
|
||||
.laantas}[šangubam]{.text}]{.lang} (spring), the month of february
|
||||
is considered a transition between the two,
|
||||
[![](chrismas/susurum.svg "susurum"){.scr
|
||||
.laantas}[susurum]{.text}]{.lang}.
|
||||
- as a result, [![](chrismas/santum.svg "santum"){.scr
|
||||
.laantas}[santum]{.text}]{.lang} (autumn) is only two months long.
|
||||
- [![](chrismas/šangubam.svg "šangubam"){.scr
|
||||
.laantas}[šangubam]{.text}]{.lang} comes from
|
||||
[![](chrismas/šani.svg "šani"){.scr .laantas}[šani]{.text}]{.lang}
|
||||
(flower) and [![](chrismas/guba.svg "guba"){.scr
|
||||
.laantas}[guba]{.text}]{.lang} (grow, thrive).
|
||||
|
||||
## putting it together
|
||||
|
||||
the word "midwinter", without any inflections, is
|
||||
[![](chrismas/þulkusim.svg "þulkusim"){.scr
|
||||
.laantas}[þulkusim]{.text}]{.lang}, which comes from
|
||||
[![](chrismas/þulku.svg "þulku"){.scr .laantas}[þulku]{.text}]{.lang}
|
||||
"be deep" and [![](chrismas/igisim.svg "igisim"){.scr
|
||||
.laantas}[igisim]{.text}]{.lang}. unusually for lántas,
|
||||
[![](chrismas/þulku.svg "þulku"){.scr .laantas}[þulku]{.text}]{.lang} is
|
||||
a verb, rather than a noun. why? who knows.
|
||||
|
||||
```{=html}
|
||||
<aside class='floating'>
|
||||
```
|
||||
on that page, where you see a [ƶ]{.lang}, replace it with [þ]{.lang}. i
|
||||
haven't got round to updating that yet. it also has the ugly text until
|
||||
i redraw [![](chrismas/č__ǧ_.svg "č ǧ"){.scr
|
||||
.laantas}[č ǧ]{.text}]{.lang}, since at least if it's all ugly it's
|
||||
consistent. sorry about that.
|
||||
|
||||
```{=html}
|
||||
</aside>
|
||||
```
|
||||
the suffix [![](chrismas/–sari.svg "–sari"){.scr
|
||||
.laantas}[--sari]{.text}]{.lang} is actually a pair of two suffixes,
|
||||
which together mean through, or during. the details of the whole
|
||||
situation are
|
||||
[here](https://lang.niss.website/laantas/nouns.html#locational-cases),
|
||||
but it is a cool two-dimensional system based on a thing that can be
|
||||
found in some languages of the caucasus. the
|
||||
[![](chrismas/–m.svg "–m"){.scr .laantas}[--m]{.text}]{.lang} on the end
|
||||
(of all these words so far, actually) is "the". so the full form
|
||||
[![](chrismas/þulkusisarim.svg "þulkusisarim"){.scr
|
||||
.laantas}[þulkusisarim]{.text}]{.lang} means "during midwinter", and
|
||||
that one [i]{.lang} is dropped in this phrase to give the form
|
||||
[![](chrismas/þulkussarim.svg "þulkussarim"){.scr
|
||||
.laantas}[þulkussarim]{.text}]{.lang}.
|
||||
|
||||
now, for [![](chrismas/ufit.svg "ufit"){.scr
|
||||
.laantas}[ufit]{.text}]{.lang}. there is a small, but technically
|
||||
non-zero, chance that you remember the word
|
||||
[![](chrismas/uf_a_t.svg "uf{a}t"){.scr
|
||||
.laantas}[uf`<u>`{=html}a`</u>`{=html}t]{.text}]{.lang} from
|
||||
[here](https://cohost.org/niss/post/3366713-ufat-iksaha), with the
|
||||
meaning of "warm". this is actually the same word, but a bit cutesy. it
|
||||
means cozy.
|
||||
|
||||
the implied verb in this sentence is
|
||||
[![](chrismas/iksaha.svg "iksaha"){.scr
|
||||
.laantas}[iksaha]{.text}]{.lang}, like before. this is an auxiliary verb
|
||||
for requests. for example, if [![](chrismas/šikkúha.svg "šikkúha"){.scr
|
||||
.laantas}[šikkúha]{.text}]{.lang} means "you are going", then
|
||||
[![](chrismas/šikkúm_iksaha.svg "šikkúm iksaha"){.scr
|
||||
.laantas}[šikkúm iksaha]{.text}]{.lang} means "please go away". the
|
||||
[--ha]{.lang} here means "you" (singular). here it's dropped because the
|
||||
phrase is long enough already to be easily understood.
|
||||
|
||||
so in the end, you get
|
||||
[![](chrismas/ufit_þulkussarim.svg "ufit þulkussarim"){.scr
|
||||
.laantas}[ufit þulkussarim]{.text}]{.lang}, meaning "\[stay\] cozy
|
||||
during the midwinter".

### [hot minute](https://en.wiktionary.org/wiki/hot_minute) <i>n.</i> {.unnumbered}
|

|

1. A long period of time.
|

2. A short period of time.
|
||||
3. An unspecified period of time.
|
||||
:::
|
||||
|
||||
for the last _hot minute_ [@hotminute], i’ve been working on a little programming language. it’s finally starting to approach a state where it can compile some programs, so maybe i should talk about it a bit.

0. it’s a *dependently typed functional language*, like your agdas and your idrises.
|
||||
1. it has a *closed type universe*. you don’t define new datatypes, but the language gives you building blocks to put them together.
|
||||
2. *[q]{.qtt-q}uantitative type theory* (qtt) [@nuttin; @qtt] is a nice combination of dependent types, resource tracking, and erasure of stuff like proofs.
|
||||
3. *[x]{.xtt-x}tt* [@xtt], which `*i sure hope i remember to come back and add this!*`
|
||||
- the closed type universe is a consequence of xtt (as well as its kinda-predecessor ott [@ott-now]), but i decided to just run with it.
|
||||
- “xtt” stands for “extensional type theory”, but it’s not _that_ extensional type theory. i know. not my fault.
|
||||
|
||||
so now you can see where the name [q]{.qtt-q}uo[x]{.xtt-x} comes from. other than my favourite dragon. anyway it also has

|
||||
|

4. *bidirectional type checking* [@bidi] `*this one too*`
|
||||
5. crude-but-effective stratification [@crude; @crude-blog] for dealing with universes. `*does this need more detail too?*`
|
||||
6. *written in idris2*. that doesn’t really have much impact on the language itself, other than the compilation process, but i’m enjoying using a dependently typed language for something substantial. even if it’s one you’re not currently supposed to be using for anything substantial. also currently it spits out scheme, like idris, because that was easy.
|
||||
7. all the non-ascii syntax is [optional], but i like it.
|
||||
|
||||
[optional]: https://git.rhiannon.website/rhi/quox/wiki/ascii-syntax
|
||||
|
||||
as for what it _doesn’t_ have: any but the most basic of conveniences. sorry.
|
||||
|
||||
|
||||
|
||||
# dependent types
|
||||
|
||||
there are lots of languages with dependent types—well, quite a few—so i won’t spend too much time on this.
|
||||
|
||||
`*but still something*`
|
||||
|
||||
|
||||
# closed type universe
|
||||
|
||||
instead of having datatypes like in normal languages, in quox you get the basic building blocks to make them. the main building blocks are functions, pairs, enumerations, equality types, strings, and natural numbers. some sort of syntactic sugar to expand a datatype declaration into this representation _is_ something i want to add, but it'd be in the pretty distant future.
|
||||
|
||||
:::aside
|
||||
_at the moment_, natural numbers are the only recursion possible. so you can define types with the same recursive structure, like lists, but binary trees and stuff are not _currently_ possible, until i replace them with something more general. probably w-types [@nlab-wtype].
|
||||
:::
|
||||
|
||||
but right now you can define a few types like this. see [qtt](#qtt) below for what all the `0`s and `ω`s mean. due to the lack of generic recursion, but the presence of _natural numbers_ specifically, a list is a length, followed by a nested tuple of that length (terminated by `'nil`).
|
||||
|
||||
```quox
|
||||
def0 Vec : ℕ → ★ → ★ =
|
||||
λ n A ⇒
|
||||
case n return ★ of {
|
||||
zero ⇒ {nil};
|
||||
succ p, As ⇒ A × As
|
||||
} -- ↖ As = Vec p A
|
||||
|
||||
def0 List : ★ → ★ = λ A ⇒ (n : ℕ) × Vec n A
|
||||
|
||||
def Nil : 0.(A : ★) → List A = λ A ⇒ (0, 'nil)
|
||||
def Cons : 0.(A : ★) → A → List A → List A =
|
||||
λ A x xs ⇒ case xs return List A of { (len, xs) ⇒ (succ len, x, xs) }
|
||||
|
||||
def NilS = Nil String
|
||||
def ConsS = Cons String
|
||||
|
||||
def example = ConsS "im" (ConsS "gay" NilS)
|
||||
|
||||
def0 example-eq : example ≡ (2, "im", "gay", 'nil) : List String =
|
||||
refl (List String) example
|
||||
```
|
||||
|
||||
you might have noticed that i didn't write the eliminator. that is because they are kind of ugly. if you want to see it anyway you can find it in [the example folder][ex].
|
||||
|
||||
[ex]: https://git.rhiannon.website/rhi/quox/src/commit/246d80eea2/examples/list.quox#L12-L25
|
||||
|
||||
|
||||
# qtt
|
||||
|
||||
sometimes, values of some type can only be used in certain ways to make sense. this is hardly controversial; if you do this with
|
||||
|
||||
|
||||
a problem that dependent types used to have a lot is that the blurring of compile-time and run-time data can lead to more being retained than necessary.
|
||||
|
||||
`*is there an example that has superlinear junk data without resorting to peano naturals or some shit*`
|
||||
|
||||
consider this vector (length-indexed list) definition from a _hypothetical language_ with normal inductive types.
|
||||
|
||||
```agda
|
||||
data Vect (A : ★) : ℕ → ★ where
|
||||
[] : Vect A 0
|
||||
_∷_ : (n : ℕ) → A → Vect A n → Vect A (succ n)
|
||||
```
|
||||
|
||||
in a totally naive implementation, `cons` would store `n`, the length of its tail (and maybe even some kind of representation of `A` too). so a three element list would look something like
|
||||
|
||||
|
||||
# xtt
|
||||
|
||||
`*mention about type-case and the closed universe*`
|
||||
|
||||
|
||||
# bidirectional type checking
|
||||

||||

title: quantity polymorphism (draft)

im getting sick of writing `elim` and `elimω`, and `fold` and `foldω` and—
|
||||
|
||||
so let's call the quantity context, uh, $Ξ$. it's just a list of bound vars.
|
||||
quantity arguments have to be full expressions though because arithmetic shows
|
||||
up in the typing rules

- out of context, `{!patta}` means door. i suppose a portal would be a magic
|
||||
door, an `{!ustaitł patta}`. but in the context of someone making one right
|
||||
in front of you, it is clear what kind of door we're talking about.
|
||||
|
||||
:::{.aside .no-line}
|
||||
the word `{!ustail}` also means "songs". did you know there's an old english
|
||||
word for magic, `{ġealdor}`, that comes from the proto-germanic `{galdr}`,
|
||||
meaning both "song" and "incantation"? i thought it was cute.
|
||||
:::
|
||||
|
||||
- the suffix pair `{!–bari}` together mean "over". there was something like this
|
||||
[last time](chrismas.html) too. since it is how the language expresses all
|
||||
spatial and temporal relationships, that's not very surprising.

:::
|
||||
|
||||
babylon no longer exists, so it doesn't need protecting. go have fun
|
||||
|
||||
- one `{!sá}` means "right at this moment". two `{!sá sá}` means "these days".
|
||||
the second one is actually pronounced with a short vowel.
|
||||
|
||||
- `{!igis}` also means "ice". "crystal" more explicitly can be `{!kut igis}`,
|
||||
or "stone ice".
|
||||
|
||||
- `{!nai}` means both "one" and "anything". phrased more literally,
|
||||
`{!lám ušmináša nat}` is "anything that we want to do".
|
||||
|
||||
- the way auxiliary verbs like "can" work is a little strange. let's take
|
||||
a shorter sentence, `{!šanil gubam fulla}`, "flowers can grow". first you take
|
||||
the base sentence, `{!šanil guba}` "flowers grow", and add `{m}`, which
|
||||
when it's not part of a grammatical template, means "the", but makes the
|
||||
clause into a noun phrase. then that is used as the subject of the verb
|
||||
`{!fulla}`, or `{!bulla}` "must", etc. so more literally, these auxiliaries
|
||||
mean something like "is possible/necessary".
|
||||
"{flowers grow here} is possible".
|
||||
|
||||
:::{.aside .no-line}
|
||||
the similarity of `{!fulla}` and `{!bulla}` is just a weird accident, in case
|
||||
you're wondering. i made the words at different times. no etymology puzzle
|
||||
here, sorry

:::
|

|

- `{!iksa}` has the same grammatical structure as `{!fulla}` above. it makes a
|
||||
sentence into a request. it has one special feature: since in the
|
||||
vast majority of cases, it only makes sense for both `{!iksa}` and the main
|
||||
verb to be second person, when that _is_ the case, only `{!iksa}` needs to
|
||||
have the person marking. otherwise it would be `{!sihaham}` above.
