My BQN library

BQN utilities. Scripts resembling these may become part of a standard library at some point but for now they're not. They shouldn't be assumed to be stable or well-tested.

Here's what there is. For usage, see export lists at the top of each file.

  • strings.bqn: common string operations like split, replace, and so on (no regex)
  • primes.bqn: fast-ish sieve with typical prime and factoring utilities
  • matrix.bqn: matrix decompositions and tools: APL ⌹ is Inverse⊘Solve
  • polynomial.bqn: complex polynomial tools and solvers
  • min.bqn: optimization/minimization methods
  • roots.bqn: find zeros of real functions
  • big{nat,int}.bqn: utilities for arbitrary-precision numbers. In progress.
  • datetime.bqn: time and date, handling formats other than BQN's native •UnixTime
  • hashmap.bqn: mutable hash table, a prototype for planned •HashMap
  • json.bqn: JavaScript Object Notation
  • csv.bqn: Comma-Separated Value file format
  • xml.bqn: eXtensible Markup Language

Run all tests with bqn test/main.bqn, or any individual test with the same name as the file in the main folder. Similarly, files in the benchmark/ folder run and report on performance measurements for the script of the same name.
