Multiple indent guides rendered at some indent levels

[tomlin7]

Bug

Multiple indent guides rendered at some indent levels. For example, see the indent level 3 in following screenshot

This is either an inconsistency caused by the bitmap used or the code, or tk itself not scaling properly.

Following code manages updation of indent guides

biscuit/src/biscuit/editor/text/text.py

Lines 287 to 319 in c75d59f

	def update_indent_guides(self) -> None:
	if self.minimalist:
	return
	self.tag_remove("indent_guide", "1.0", "end")
	self.tag_remove("current_indent_guide", "1.0", "end")
	lines = self.get("1.0", "end-1c").split("\n")
	self.current_indent_level = self.get_current_indent_level() - 1
	for line_number, line in enumerate(lines, start=1):
	indent_level = self.calculate_indent_level(line)
	if indent_level > 0:
	self.add_indent_guide(line_number, indent_level)
	def calculate_indent_level(self, line: str) -> int:
	indent = len(line) - len(line.lstrip())
	return indent // self.base.tab_spaces
	def add_indent_guide(self, line_number: int, indent_level: int) -> None:
	for level in range(indent_level):
	start_index = f"{line_number}.{level * self.base.tab_spaces - 1}"
	end_index = f"{line_number}.{level * self.base.tab_spaces + 1}"
	self.tag_add(
	(
	"current_indent_guide"
	if level == self.current_indent_level
	else "indent_guide"
	),
	start_index,
	end_index,
	)

The indent guide uses following bitmaps

biscuit/src/biscuit/editor/text/text.py

Lines 136 to 145 in c75d59f

	self.tag_configure(
	"indent_guide",
	bgstipple=f"@{self.indentguide_stipple}",
	background=self.base.theme.border,
	)
	self.tag_configure(
	"current_indent_guide",
	bgstipple=f"@{self.indentguide_stipple}",
	background=self.base.theme.secondary_foreground,
	)
