cs-gimmicks 20250428

Gimmicks and hacks to make some of my other modules more robust and less demanding of others.

Gimmicks and hacks to make some of my other modules more robust and less demanding of others.

Latest release 20250428: Define Buffer from collections.abc.Buffer, or from typing.ByteString for older Pythons.

Short summary:

• open_append: Ghastly hack to open something for append entirely because some Linux systems do not let you open a character device for append. Tries sane 'a' and falls back through 'r+' and finally to 'w' only if path refers to a character device.

Module contents:

• debug(*a, **kw): Wrapper for debug() which does a deferred import.
• error(*a, **kw): Wrapper for error() which does a deferred import.
• exception(*a, **kw): Wrapper for exception() which does a deferred import.
• info(*a, **kw): Wrapper for info() which does a deferred import.
• log(*a, **kw): Wrapper for log() which does a deferred import.
• open_append(path): Ghastly hack to open something for append entirely because some Linux systems do not let you open a character device for append. Tries sane 'a' and falls back through 'r+' and finally to 'w' only if path refers to a character device.
• r(obj): simplistic versions of cs.lex r() and s()
• trace(*a, **kw): Wrapper for info() which does a deferred import.
• warning(*a, **kw): Wrapper for warning() which does a deferred import.
