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

Fast parsing of arguments

Call arbitrary functions to check argument values

String arguments

Flag arguments
