asstagparser 2.4.1

ass_tag_parser

A Python library for serialization and deserialization of ASS subtitle file
format tags markup.
Not to confuse with parsing .ass files that can be manipulated with
ass_parser.
Example:
from ass_tag_parser import parse_ass

result = parse_ass(
r"{\an5\pos(175,460)\fnUtopia with Oldstyle figures\fs90\bord0\blur3"
r"\1c&H131313&\t(0,1000,2,\1c&H131340&)\t(1000,2000,\1c&H1015B2&"
r"\blur1.4)}Attack No. 1{NOTE:アタックNo.1}"
)
print(result)
print(result[2].meta)

Result:
[
AssTagListOpening(),
AssTagAlignment(alignment=5, legacy=False),
AssTagPosition(x=175.0, y=460.0),
AssTagFontName(name="Utopia with Oldstyle figures"),
AssTagFontSize(size=90.0),
AssTagBorder(size=0.0),
AssTagBlurEdgesGauss(weight=3.0),
AssTagColor(red=19, green=19, blue=19, target=1, short=False),
AssTagAnimation(
tags=[AssTagColor(red=64, green=19, blue=19, target=1, short=False)],
time1=0.0,
time2=1000.0,
acceleration=2.0,
),
AssTagAnimation(
tags=[
AssTagColor(red=178, green=21, blue=16, target=1, short=False),
AssTagBlurEdgesGauss(weight=1.4),
],
time1=1000.0,
time2=2000.0,
acceleration=None,
),
AssTagListEnding(),
AssText(text="Attack No. 1"),
AssTagListOpening(),
AssTagComment(text="NOTE:アタックNo.1"),
AssTagListEnding(),
]
Meta(start=5, end=18, text="\\pos(175,460)")

Starting from version 2.2, drawing commands are parsed automatically.

Serializing the tree back
ASS tree: compose_ass. Note that you don't need to supply AssTagListOpening
nor AssTagListEnding tags in the input item list – this function inserts them
automatically.
Draw commands: compose_draw_commands.
