Tools
Basic usage – from pocketutils.full import Tools
Tools.zip_strict([1, 2, 3], [5, 6]) # error <-- lengths must match
Tools.strip_brackets("( (xy)") # "(xy" <-- strips paired only
Tools.sanitize_path("x\ty") # "xy" <-- very robust cross-platform sanitization
Tools.delete_surefire("my_file") # <-- Attempts to fix permissions if needed
Tools.git_description("my_repo").tag # <-- get git repo info
Tools.pretty_function(lambda s: None) # "<λ(1)> <-- decent name for any object
Tools.roman_to_arabic("XIV") # 14 <-- inverse function too
Tools.delta_time_to_str(delta_sec=60 * 2 + 5) # "02:05" <-- handles days too
Tools.round_to_sigfigs(135.3, 2) # 140 <-- rounding to sigfigs-proper
Tools.pretty_float(-float("-inf")) # "−∞" <-- proper unicode, no trailing 0s
Tools.stream_cmd_call(["cat", "big-file"], callback=fn) # <-- buffer never fills
Tools.strip_off("hippopotamus", "hippo") # "potamus" <-- what .strip() should do
Tools.strip_quotes("'hello'") # "hello"
Tools.truncate10("looong string") # "looong st…"
Tools.parse_bool("true") # True
Tools.parse_bool_flex("yes") # True
Tools.look(item, "purchase.buyer.first_name") # None if purchase or buyer is None
Tools.friendly_size(n_bytes=2 * 14) # "16.38 kb"
Tools.is_probable_null("NaN") # True
Tools.is_true_iterable("kitten") # False
Tools.or_null(some_function) # None if it fails
Tools.or_raise(None) # raises an error (of your choice)
Tools.trash(unwanted_file) # move to os-specific trash
Tools.pretty_dict({"contents": {"greeting": "hi"}}) # indented
Tools.save_diagnostics(Tools.get_env_info()) # record diagnostic info
Tools.is_lambda(lambda: None) # True
Tools.longest(["a", "a+b"]) # "a+b" # anything with len
Tools.only([1, 2]) # error -- multiple items
Tools.first(iter([])) # None <-- better than try: next(iter(x)) except:...
Tools.trace_signals(sink=sys.stderr) # log traceback on all signals
Tools.trace_exit(sink=sys.stderr) # log traceback on exit
# lots of others
