Macro: vv (&body body) ¶

the vv macro implements a DSL for manipulating packs of values and/or row
vectors. it is called as a part of vprogn, fvprogn, vdef and fvdef. but can
also be used explicitly via the (vv ...) macro or (veq::vv-proc ...) function.

you can read about the motivation behind vv at: https://inconvergent.net/2023/a-vector-dsl/

the DSL uses triggers to broadcast a function (symbol name) or code across
packs of 1-9 values and/or rows of 1-9 item vectors.

; lets start with a simple example

(i2!@+ 1 2 3 4) ; -> (values (+ 1 3) (+ 2 4))

; where:
; - i is the type (fixnum)
; - 2 is the dimension / size of the value packs
; - !@ is the trigger for this particular mode; and
; - + is the function name

; i2!@+ requires 4 values, but it is agnostic to the grouping of the values in
; the input

(i2!@+ (values 1 2) 3 4) ; -> (values (+ 1 3) (+ 2 4))
(i2!@+ 1 (values 1 2 3 4)) ; -> (values (+ 1 3) (+ 2 4))
(i2!@+ 1 (values 2 3) (+ 7 8)) ; -> (values (+ 1 3) (+ 2 (+ 7 8)))

; here are other possible configurations for !@

; same behaviouir as above
(2!@* 1 2 3 4) ; -> (values (* 1 3) (* 2 4))
; project last value
(2!@*. 1 2 3) ; -> (values (* 1 3) (* 2 3))
; project first value
(2!@.* 1 2 3) ; -> (values (* 1 2) (* 1 3))
; project two values on r side
(2!@*.. 1 2 3 4) ; -> (values (* 1 3 4) (* 2 3 4))

; several modes also support arrays ($)

; array on l side
(2!@$* #(1 2 3 4) 5 6) ; -> #((* 1 5) (* 2 6)
; (* 3 5) (* 4 6))
(2!@$*. #(1 2 3 4) 5) ; -> #((* 1 5) (* 2 5)
; (* 3 5) (* 4 5))
; array on both sides
(2!@$+$! #(1 2 3 4) #(10 20 30 40)) ; -> #(11 22 33 44)
; array on r side only is currently not supported

; expressions can be nested, so a 2d dot product might look like this

(2_@+ (2!@* (values 1 2)
(values 3 4))) ; -> (+ (* 1 3) (* 2 4))

; here we introduce another mode (_@) that will call the function on the input
; values. a simpler example

(2_@+ (values 2 3)) ; -> 5

; so, if you have two arrays, you can do row-wise dot products in a similar way

(21_@$+ (2!@$*$ #(2 2 3 4)
#(4 3 2 1))) ; -> #(14 10)

; notice that 21_@$+ has two dimension digits. the second digit is the expected
; output dimension. as such this command will reduce the number of columns from
; 2 to 1. by default the output dim is the same as the input dim. output
; dimension is supported on all array ($) modes.

; here are some slightly more involved examples using the _@ mode

(labels ((swap (x y) (values y x))
(do-thing (x y z) (values (+ y z) (+ x z))))
; swap columns on each row
(2_@$swap #(2 1 4 3)) ; -> #(1 2 3 4)
; swap columns on each row
(2_@$swap (?@ #(2 1 4 3))) ; -> #(1 2 3 4)
; swap columns in place (!) on all rows except 0
(2_@$swap! (?@ #(2 1 4 3 6 5) 1)) ; -> #(2 1 3 4 5 6)
; project 5 and call do-thing on each row
(2_@$do-thing. #(1 2 3 4) 5)) ; -> #((+ 2 5) (+ 1 5)
; (+ 4 5) (+ 3 5))

; as opposed to calling a function on rows or values, you can use .@ to call a function on all elements

(2.@abs -1 -2) ; -> (values (abs -1) (abs -2))

; or with arrays

(2.@$abs #(-1 -2 -3 -4)) ; -> #((abs -1) (abs -2)
; (abs -3) (abs -4))

; slicing will still work as in the previous examples

(2.@$abs! (?@ #(-1 -2 -3 -4) 1)) ; -> #(-1 -2 (abs -3) (abs -4))

(m@list 1 (values 2 3) 4) ; -> ’(1 2 3 4)

; prints array in two rows with row number:
(2x@$fx #(1 2 3 4) ((i x y) (print (list i :xy x y)))) ; -> nil
; > (0 :xy 1 2)
; > (1 :xy 3 4)

; fcos-sin returns points on a circle at 10 angles,
; then scales the circle by 8f0
; f12 means that fcos-sin takes 1 value and returns 2 values (per row)
(f2!@$*. (veq::f12_@$fcos-sin ; must use :: if outside veq
(veq:f$lspace 10 0f0 veq:fpii))
8f0) ; -> #(8.0 0.0 ...)

; sum all rows:
(2r@$+ #(0 1 2 3 4 5 6 7 8 9)) ; -> (values (+ 0 2 4 6 8) (+ 1 3 5 7 9))
; sum all rows from row 2:
(2r@$+ (?@ #(0 1 2 3 4 5 6 7 8 9) 2)) ; -> (values (+ 4 6 8) (+ 5 7 9))
; sum rows 0 1 3 from vector with indices:
(2r@$+ (v?@ #(0 1 2 3 4 5 6 7 8 9) #(0 1 3))) ; -> (values (+ 0 2 6) (+ 1 3 7)) ; or, using an index list:
(2r@$+ (l?@ #(0 1 2 3 4 5 6 7 8 9) ’(0 1 3))) ; -> (values (+ 0 2 6) (+ 1 3 7))

MODES

the current modes and corresponding triggers are as follows:

– d!@: call fx on pairs of values and/or rows of values from arrays

- d!@fx: d values, d values
- d!@fx.: d values, [number of dots] values
- d!@$fx: d array, d values
- d!@$fx$: d array, d array
- d!@$fx.: d array, [number of dots] values

– _@: call fx on n values, or rows of values from array

- d_@fx: d values
- d_@$fx: d array
- d_@$fx.: d array, [number of dots] values

– d.@: call fx on individual elements from values, rows of values from array

- d.@fx: d values
- d.@$fx: d array

the following modes have more specific behaviour:

- d%@$fx: map fx across rows of values from array. see below.
- dr@$fx: reduce rows with fx vertically. see below.

- m@fx: translates to (mvc #’fx ...)

- ?@ is a modifier used to alter the behaviour of a specific mode.

MODE MODIFIERS: ARRAY SLICING/INDEXING

modes that involve arrays ($) support slicing rows by wrapping the array in

(?@ arr from [to])

for ivec, pvec, list or vector indices, append i, p, l or v respective to the modifier. here are some examples of behaviour. the types are described below.

(labels ((take2 ((:va 2 x)) (values x)))

; slice from index
(2_@$take2 (?@ #(1 2 3 4 5 6 7 8) 2)) ; -> #(5 6 7 8)
; slice to from index
(2_@$take2 (?@ #(1 2 3 4 5 6 7 8) 2 3)) ; -> #(5 6)

; vector index
(2_@$take2 (v?@ #(1 2 3 4 5 6 7 8) #(0 3))) ; -> #(1 2 7 8)
; list index
(2_@$take2 (l?@ #(1 2 3 4 5 6 7 8) ’(0 3))) ; -> #(1 2 7 8)

(2!@$+$! (?@ #(1 2 3 4) 1) (?@ #(10 20 30 40) 0 1))) ; -> #(1 2 13 24)

TYPES

all vv vv expressions (except m@ where it does not make sense) can be explicity typed. the supported types, wtih corresponding array type are as follows

- f: veq:ff, single-float; veq:fvec
- d: veq:df, double-float; veq:dvec
- i: veq:in, fixnum, veq:ivec
- p: veq:pn, (unsigned-byte 31); veq:pvec
- s: veq:sy, symbol; veq:svec
- k: veq:kv, keyword; veq:kvec
- l: veq:ll, list; veq:lvec
- none; vector

fvec, ivec, etc are simple-arrays with the coresponding type. ie. veq:fvec
means (simple-array veq:ff). when type is omitted, the code will be more
forgiving, but less efficeint. in which case the corresponding array type is ’vector.

INSPECT CODE

the code that is actually generated is usually a little more involved than what these examples imply. in order to see the expanded code, the easiset is to wrap
the code in veq:mac, which displays the code after it has been expanded:

(veq:fvprogn (veq:mac (2!@$*. #(1 2 3 4) 5)))

alternatively, use:

(print (veq::vv-proc ’(2!@$*. #(1 2 3 4) 5)))

Macro: xlet (all-vars &body body) ¶

xlet is a macro to bind typed values, and other variables: (veq:xlet ((f2!a (f2 1f0 2f0)) ; 2d veq:ff/float
(d!b 1d0) ; 1d veq:df/double
(h :a)
(i4!c (values 1 2 3 4))) ; 4d veq:in/integer (declare (keyword h))
(do-something a b c h))

names without ! will be treated (mostly) as in a regular let. declare can be used to declare types.
NOTE: xlet behaves more like CL let* in that bindings are available immediately.
