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
