vig

a v parser in zig, also a shitpost taken too far

(will likely be done as a full compiler, who knows, leave a like and subscribe for more epic adventures)

why

• because i want to learn parsers and what best to do it with a language i'm negatively charged towards
• theres an ast now it looks pretty
• i finally understand recursive descent parsers

variations

• for is split between for and loop because my fucking god i cant stand having four different variations of for to parse.

• struct initialization is with Struct.{}, not Struct{}, to remove parsing ambiguities (if a {} and a{}, v solves that with case, e.g structs Must Be Properly Titled and i can't bother with that)

• function parameters must have a type always (no fn blah(x, y int), must be fn blah(x int, y int))

• ifs are always statements, not expressions (can't use if as an r-value: x := if ...)

• no ++, -- (use += and -=)

• no match

• no embedded structs

• no enum literals (x = .val2)

• no v orm

• no codegen

• no inline assembly

wip

• no for yet
• no map yet
• no in yet (probably will be dropped)
• no module, import yet
• no interfaces yet
• no generics yet
• no attributes yet ([live], [skip])
• no defer yet
• no switch yet
• no operator overloading methods yet
• do we really want a type system (optionals included)
  • no error handling yet (call() or {blah})
  • no ? postfix operator yet (call()?)
• do we really want to output c
• do we really want to output llvm
• do we really want to output x86

how

• step 1: dab
• step 2:

git clone https://gitdab.com/luna/vig.git
cd vig
zig build install --prefix ~/.local/
