pylib

Shared libraries for my personal work.

jfileutil.py

Simple file pickling functionality for storing and loading JSON objects.

loom.py

Provides threading capabilities, including Spools, which allow for powerful, simple, grouped threading implementation in very simple statements.

import loom

work = []
spool = loom.Spool(4)	# Initialize a Spool with a quota size of 4.

for i in range(0, 10):
    spool.enqueue(target=work.append, args=(i,))
# At this point in the code, up to 4 threads will be running to finish this job.
assert (len(work) >= 0) and (len(work) <= 10) # This is guarenteed. 

spool.finish()  # Block the current code until each job is complete.
assert len(work) == 10  # This is also guarenteed.

You can also use threads as context managers, allowing them to finish themselves appropriately.

import loom

work = []
with loom.Spool(4) as spool:	# Initialize a Spool with a quota size of 4.
    for i in range(0, 10):
        spool.enqueue(target=work.append, args=(i,))
    # At this point in the code, up to 4 threads will be running to finish this job.
    assert (len(work) >= 0) and (len(work) <= 10) # This is guarenteed. 
# At the end of the context session, Spool will finish its work before continuing. No manual .finish() call required.
assert len(work) == 10  # This is also guarenteed.

Behind the scenes, loom is doing the following:

Maintaining a queue of tasks
Starting tasks to maximize running threads without exceeding its quota
Maintaining a list of live threads it started
Waiting for its threads to finish, and dequeuing more threads if appropriate

Spools also have the ability to

Ensure all running tasks finish before starting more threads, by request

pwidgets.py

Additional widgets for progressbar

snip.py

Very basic helper functions.

tkit.py

Additional tkinter widgets and utility functions for GUI programming

`JSONEditor`

A user-friendly GUI that allows live manipulation of JSON data by the user. Designed for use as a settings editor. Uses tabbed views and supports the full json standard, including lists and nested dictionaries.

`MultiColumnListbox`

A widget that uses the ttk.TreeView widget as a fully interactive table

`ToggleButton`

A subclass of ttk.Checkbutton that acts as a simple interface for Metro/Material/iOS style toggle switches.
