CL-SDM

CL-SDM is my personal standard library for Common Lisp. It’s not quite at v1.0 yet, and is written in a rather opinionated way. Most of my other Common Lisp projects use it in some way or another.

Features

• Core
  • XOR logic function.
  • Nicer constant declarations.
  • PARSE-INTEGER? that returns NIL instead of raising a condition when it can’t parse.
  • Shorter type names for the common (un)signed integer types
  • Shorter array/vector declarations
  • Pseudo-enums (code is already written, just needs moving to CL-SDM and some expansion)
  • DEFINE-TYPED-FN ported from my CL-MeltySynth program and expanded
  • [/] Support for &key, &optional, and &rest in DEFINE-TYPED-FN
  • Conversion to/from (un)signed integers
  • CLAMP macro
  • MAPAPPEND function
  • Various nice functions inspired by Crystal/Ruby for inspecting sequences.
  • SAMPLE function
  • Sequence shuffling
  • SHIFT functions
  • Generic DOSEQ macro
  • Equivalent of LAST for any sequence type.
  • SWAP function
  • Easier string trimming
  • Caseless string comparisons
  • CASE-like statement for strings
  • Easier concatenation of things to a string
  • Print numbers as binary sizes (KiB, MiB, etc).
  • String spitting
  • Pretty string indenting
  • STRING-REPLACE
  • STRING-STARTS-WITH and -ENDS-WITH
  • JOIN function for strings
  • Fast approximate trig functions
• Argument Parsing
  • Support short (-s) and long (--long) arguments.
  • Automatic –help and –version handling
  • Custom help/version printing
  • Positional arg support
  • Fast parsing of arguments
  • Call arbitrary functions to check argument values
  • String arguments
  • Flag arguments
  • File arguments (like strings, but with some special handling)
  • Numeric arguments
  • Make positional arg support optional
  • Optionally allow - and – as arguments
• I/O
  • Fast I/O functions for reading/writing integers in binary.
  • Fast I/O functions for reading/writing floats in binary.
  • Fast I/O functions for reading/writing strings in binary.
  • Conversion of strings to/from sequences of bytes.
  • Conversion of integers to/from sequences of bytes.
  • Conversion of floats to/from sequences of bytes.
  • 24-bit integer support in the I/O functions
• Date/Time
  • Date/Time arithmetic
  • Time Spans
  • Support fractional seconds
  • Time Span -> String conversions
  • Date Time -> String conversions
• Terminal Handling
  • Basic ANSI support for colors and cursor control
  • Progress bar
  • Support for the Terminology terminal
  • Windows support
• Files/Pathnames
  • Basename
  • Check for existing directory
  • Get file size
  • Check if a path points to a directory or not
  • Get some basic info (last modified, mode, etc.)
• Logging
  • Tag-based logging, where tags can be muffled.
  • Basic logger
  • Logger with colored output
  • Multi-logger (write to a logger once, and the strings go to 1+ destinations)
  • Concurrent logger
