The haq-paq General Utilities Library from Version 1 allows developers to get a head start on writing many of the basic utility functions found across q codebases. The library is split across themed packages with each package existing as an independent, easily loadable q script.
For documentation on how to use the functions, click here.
These libraries (except the benchmark library) have unit tests which are stored in a private repository.
Covers a wide range of functionality that is normally found in other packages for languages (such as Python's NumPy). This package includes prime number calculation, list creation functions similar to those that exist in NumPy (such as linspace), calculating modal values and rounding functionality.
Has a variety of useful functions to assist when working with dates or timestamps in q. This package includes getting start/end dates of a week/month, returning only weekdays from a range of dates or converting timestamps between Unix and q .
Useful for formatting information into strings, such as making numbers human readable,
adding comma separators and replacing text tokens (similar to format() in Python).
A basic standardized way to write messages, errors and memory stats to log files.
Simple ways of benchmarking execution times for subsections of functions.
Contains a wide variety of helpful functionality for dealing with tables. This ranges from fixing issues with splayed tables on disk to using integer partitioning.
Includes extra utility functions such as efficiently counting a sym file's length and generically typed dictionary creation.
