The Scarlet Devil Mansion :: 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.

Source Code

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
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

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.
24-bit integer support in the I/O functions

Date/Time

Date/Time arithmetic
Time Spans
Date Time -> String conversions

Terminal Handling

Basic ANSI support for colors and cursor control
Progress bar
Support for the Terminology terminal

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
