- rename MondoRunner.call => .evaluate - can now evaluate leafs - remove .( because it's confusing and half baked - support (.) as id function

# mondo
|
|
|
|
an experimental parser for an *uzulang*, a custom dsl for patterns that can stand on its own feet. more info:
|
|
|
|
- [uzulang I](https://garten.salat.dev/uzu/uzulang1.html)
|
|
- [uzulang II](https://garten.salat.dev/uzu/uzulang2.html)
|
|
|
|
```js
|
|
import { MondoRunner } from 'uzu'
|
|
|
|
const runner = MondoRunner({ seq, cat, s, crush, speed, '*': fast });
|
|
const pat = runner.run('s [bd hh*2 (cp.crush 4) <mt ht lt>] . speed .8')
|
|
```
|
|
|
|
the above code will create the following call structure:
|
|
|
|
```lisp
|
|
(speed
|
|
(s
|
|
(seq bd
|
|
(* hh 2)
|
|
(crush cp 4)
|
|
(cat mt ht lt)
|
|
)
|
|
) .8
|
|
)
|
|
```
|
|
|
|
you can pass all available functions to *MondoRunner* as an object.

### things mondo cant do
|
|
|
|
how to write lists?
|
|
|
|
```js
|
|
arrange(
|
|
[4, "<c a f e>(3,8)"],
|
|
[2, "<g a>(5,8)"]
|
|
).note()
|
|
```
|
|
|
|
how to write objects:
|
|
|
|
```js
|
|
samples({ rave: 'rave/AREUREADY.wav' }, 'github:tidalcycles/dirt-samples')
|
|
```
|
|
|
|
how to access array indices?
|
|
|
|
```js
|
|
note("<[c,eb,g]!2 [c,f,ab] [d,f,ab]>").arpWith(haps => haps[2])
|
|
```
|
|
|
|
s hh .struct(binaryN 55532 16)
|
|
|
|
comments
|
|
|
|
variables: note g2*8.dec sine
|
|
|
|
n (irand 8. ribbon 0 2) .scale"C minor" => lags because no whole
|
|
|
|
### reference
|
|
|
|
- arp: note <[c,eb,g] [c,f,ab] [d,f,ab]> .arp [0 [0,2] 1 [0,2]]
|
|
- bank: s [bd sd [- bd] sd].bank TR909
|
|
- beat: s sd .beat [4,12] 16
|
|
- binary: s hh .struct (binary 5)
|
|
- binaryN: s hh .struct(binaryN 55532 16) => is wrong
|
|
- bite: n[0 1 2 3 4 5 6 7].scale"c mixolydian".bite 4 [3 2 1 0]
|
|
- bpattack: note [c2 e2 f2 g2].s sawtooth.bpf 500.bpa <.5 .25 .1 .01>/4.bpenv 4
|
|
|
|
### dot is a bit ambiguous
|
|
|
|
```plaintext
|
|
n[0 1 2].scale"C minor".ad.1
|
|
```
|
|
|
|
decimal vs pipe
|
|
|
|
### less ambiguity with [] and ""
|
|
|
|
in js, s("hh cp") implcitily does [hh cp]
|
|
in mondo, s[hh cp] always shows the type of bracket used
|
|
|
|
### todo
|
|
|
|
- lists: C:minor
|
|
- spread: [0 .. 2]
|
|
- replicate: !
