Parse ASS subtitle format tags markup.
Project description
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
.
