Jacinda is a functional, expression-oriented data processing language, complementing AWK.

Installation

Releases

There are binaries for some platforms on the releases page.

If you are on Mac, you will need to install *-librure.dylib as well.

From Source

First, install Rust's regex library. You'll need to put librure.so or librure.dylib etc. in the appropriate place.

If you have cabal and GHC installed (perhaps via ghcup):

cabal install jacinda

Editor Support

There is a vim plugin and a VSCode extension.

Rosetta

Replace

NF == 1 && $1 != "}" {
  haveversion[$1] = 1
}
END {
  for (i in haveversion)
    printf "have-%s = yes\n", i
}

with

(sprintf 'have-%s = yes')" ~.{nf=1 & `1 != '}'}{`1}

Documentation

See the guide, which contains a tutorial on some of the features as well as examples.

The manpages document the builtins and provide a syntax reference.

Status

Missing Features & Bugs

• No nested dfns
• No list literal syntax
• Postfix :f and :i are handled poorly
• Polymorphic functions can't be instantiated with separate types (global monomorphism restriction)

Intentionally missing features:

• No loops

Advantages

• Rust's regular expressions
  • extensively documented with Unicode support
• Deduplicate builtin
