Add nockma evaluator (#2564) This PR adds an parser, pretty printer, evaluator, repl and quasi-quoter for Nock terms. ## Parser / Pretty Printer The parser and pretty printer handle both standard Nock terms and 'pretty' Nock terms (where op codes and paths can be named). Standard and pretty Nock forms can be mixed in the same term. For example instead of `[0 2]` you can write `[@ L]`. See https://github.com/anoma/juvix/blob/a6028b0d92e2dff02329ab7f441bf48ccdeb3eb3/src/Juvix/Compiler/Nockma/Language.hs#L79 for the correspondence between pretty Nock and Nock operators. In pretty Nock, paths are represented as strings of `L` (for head) and `R` (for tail) instead of the number encoding in standard nock. The character `S` is used to refer to the whole subject, i.e it is sugar for `1` in standard Nock. See https://github.com/anoma/juvix/blob/a6028b0d92e2dff02329ab7f441bf48ccdeb3eb3/src/Juvix/Compiler/Nockma/Language.hs#L177 for the correspondence between pretty Nock path and standard Nock position. ## Quasi-quoter A quasi-quoter is added so Nock terms can be included in the source, e.g `[nock| [@ LL] |]`. ## REPL Launch the repl with `juvix dev nockma repl`. A Nock `[subject formula]` cell is input as `subject / formula` , e.g: ``` nockma> [1 0] / [@ L] 1 ``` The subject can be set using `:set-stack`. ``` nockma> :set-stack [1 0] nockma> [@ L] 1 ``` The subject can be viewed using `:get-stack`. ``` nockma> :set-stack [1 0] nockma> :get-stack [1 0] ``` You can assign a Nock term to a variable and use it in another expression: ``` nockma> r := [@ L] nockma> [1 0] / r 1 ``` A list of assignments can be read from a file: ``` $ cat stack.nock r := [@ L] $ juvix dev nockma repl nockma> :load stack.nock nockma> [1 0] / r 1 ``` * Closes https://github.com/anoma/juvix/issues/2557 --------- Co-authored-by: Jan Mas Rovira <janmasrovira@gmail.com> Co-authored-by: Lukasz Czajka <lukasz@heliax.dev>

Fast nockma eval (#2580) Adds annotations to cells to indicate that it is a call to the stdlib and might be evaluated faster in the Haskell evaluator. The syntax for stdlib calls is as follows: ``` [stdlib@add args@<args-term> <left-term> <right-term>] ``` where `add` is the name of the function being called, `<args-term>` is a nockma term that points to the position of the arguments, and `<left-term>` and `<right-term>` are the actual components of the cell.
