PySimpleGUI Code Finder & Launcher
Use to filter and search your source code tree.
Then run or edit your files
Filter the list of :
* Search using filename
* Searching within the programs' source code (like grep)
The basic file operations are
* Edit a file in your editor
* Run a file
* Filter file list
* Search in files
* Run a regular expression search on all files
* Display the matching line in a file
Additional operations
* Edit this file in editor
Keeps a "history" of the previously chosen folders to easy switching between projects

# So you face a prediciment here. You wish to read files, both small and large; however the bigger the file/bigger the list, the longer to read the file.
# This probably isn't what you want, right?
# Well, we can't use a direct command line to run grep and parse. But it is an option. The user may not have it.
# We could check if grep exists and if not use our method; but it isn't the best way.
# So using background knowldge, we know that grep is *very* fast.
#
# Why?
# Grep reads a *ton* of files into memory then searches through the memory to find the string or regex/pattern corresponding to the file.
# How can we load a file into memory on python as fast as grep whilst keeping it universal?
# memory mapping (mmap).
# We can't load a lot of files into memory as we may face issues with watchdog on other operating systems. So we load one file at a time and search though there.
# This will allow the fastest searching and loading of a file without sacrificing read times.
# 2.8 seconds on the highend for both small and large files in memory.
# We also don't have to iterate over lines this way.
