@Javagedes Javagedes commented Aug 28, 2023

This commit adds support for including multiple relative paths from the same directory by storing a stack of all included files that have not finished being parsed, and the number of lines that still need to be parsed in each file.

Previously, only includes of nested relative paths were supported as the currently parsed file was not reverted to the previous file when the parsing of an included file was completed. This led to further includes needing the be relative to the latest included file.

closes #394

NIT:

Since you're likely dealing with a large set of data, the following solution probably doesn't make a lot of sense performance wise but if you wanted to improve readability of the code you could do something like a namedtuple.

However the object instantiation might be too much for a large dataset

from collections import namedtuple

# Define the namedtuple type
FilePathRecord = namedtuple('FilePathRecord', ['filepath', 'line_count'])

self.FilePathStack = []  # a stack containing FilePathRecord instances

self.FilePathStack.append(FilePathRecord('my_file_path', 100))

self.FilePathStack[0].file_path

return False
line_count = self.FilePathStack[-1][1]
if line_count - 1 > 0:
self.FilePathStack[-1][1] -= 1
