Aegisub Automation documentation
Version 3
Copyright 2005 Niels Martin Hansen.
---
This document describes version 3 of the automation system used in Aegisub.
The automation system uses the Lua language for scripting engine.
See <http://www.lua.org/> for more information.
---
What is Automation?
Aegisub Automation is a scripting system designed to automate many processing
tasks of ASS subtitles, instead of using tedious, error-prone manual
processing. The primary purpose is creating karaoke effects for anime fansubs.
The Automation script is given the complete subtitle data from a subtitle
file, in a format suited for creating special effects.
The script will return a complete substiture for the original subtitle
data, allowing full freedom of processing.
A number of helper functions are provided, to aid in finding errors in
scripts, as well as retrieve further data about the subtitles, needed to
created advanced effects.
---
Scripts, files, functions:
A script is a file containing Lua code. One file can define just one script,
but several scripts can share code by the help of including other files.
All scripts are run in a separate interpreter, and as such don't have any way
of interacting with other loaded scripts.
All strings in a script should be in UTF-8 encoding, without byte-order mark.
All strings input to a script are encoded as UTF-8.
Script files may start with an UTF-8 BOM (byte-order mark) or not, but this
is currently not well tested.
A script must define certain global variables:
version
Number. Version of the scripting interface used.
The version described in this file is 3.
To comply with version 3, version must be: 3 <= version < 4
kind
String. Not used, but mandatory. Set it to "basic_ass" for now.
name
String. Displayed name of the script.
description
String. Optional. Long description of the script.
process_lines
Function. The main script function.
configuration
Table. Optional. Configuration options for the script.
The functions are described in detail in the following.
The script may define further global variables, but they do not have any
special meaning. Be aware, however, that later versions of the scripting
system might define further global variables with special meanings, so be
careful choosing names for private use globals.
It's recommended to prefix private global variables with "p_"; the scripting
system will never assign special meanings to global variables with that
prefix.
The scripting system defines a global variable with name "aegisub", which
contains important values. You should not hide the "aegisub" variable.
---
The processing function:
The processing function is the heart of the script.
It takes as input some meta-information about the subtitles, the styles
used in the subtitles, as well as the actual subtitle data to process.
The output is a set of subtitle data in the same format as the input.
The output subtitle data will be used as a complete replacement of the
input data.
Future versions might allow modifying style data and meta data as well.
The processing function is defined as follows:
function process_lines(meta, styles, lines, config)
The arguments are:
@meta
Table. Meta information about the script. (Script Info section.)
@styles
Table. Style definitions. (V4+ Styles section.)
@lines
Table. Subtitle events. (Events section.)
@config
Table. Values set for the configuration options provided. If no
configuration options were provided, this will be an empty table.
Returns: One value.
This value must be a table, using the same format as @lines.
Note that the indexes in the return value may be either zero-based or
one-based, to allow for greater compatibility. You are encouraged to
use one-based indexes.
Description of @meta:
This is a table with the following keys:
res_x
Horizontal resolution of the script.
res_y
Vertical resolution of the script.
Description of @styles:
This is a table with the following keys:
-1
Number. The amount of styles defined, called "n".
0 -> n-1
Table. The actual style definitions.
<string "name">
Table. The style definition with the specified name.
The key -1 is used for count rather than "n", since one might have a style
definition with the name "n".
A style definition is a table with the following keys:
name
String. Name of the style.
fontname
String. Name of the font used.
fontsize
Number. Size of the font used.
color1
String. Primary color.
All color fields use raw hexadecimal format, that is, no special characters
before or after the hex string.
color2
String. Secondary color.
color3
String. Outline color.
color4
String. Shadow color.
bold
Boolean. Bold text or not.
italic
Boolean. Italic text or not.
underline
Boolean. Underlined text or not.
strikeout
Boolean. Striked-out text or not.
scale_x
Number. Horizontal scale.
scale_y
Number. Vertical scale.
spacing
Number. Spacing between characters.
angle
Number. Rotation angle in degrees.
borderstyle
Number. 1=Outline + drop shadow, 3=Opaque box (not really used???)
outline
Number. Thickness of outline.
shadow
Number. Distance of shadow from text.
align
Number. Numpad style alignment.
margin_l
Number. Left margin in pixels.
margin_r
Number. Right margin in pixels.
margin_v
Number. Vertical margin in pixels.
encoding
Number. Font encoding used.
Description of @lines:
This is a table with the following keys:
n
Number. The amount of lines.
0 -> n-1
Table. The actual lines.
A line is a table with the following key:
kind
String. Can be "blank", "scomment", "comment" or "dialogue".
The keys otherwise defined depends on the kind of the line.
If the kind if "blank", no further fields are defined.
If the kind is "scomment", the line is a "semicolon comment", and the
following key is defined:
text
String. Text following the semicolon until end of line. EOL not included.
If the kind is "comment" or "dialogue", the line is either a Comment: or
a Dialogue: line. In both cases, the following keys are defined:
layer
Number.
start_time
Number. Start time of line in centiseconds.
(Might change to userdata later.)
end_time
Number. End time of line in centiseconds.
(Might change to userdata later.)
style
String. Style used for this line.
name
String. Character name speaking this line.
margin_l
Number. Left margin override, in pixels. (0=no override)
margin_r
Number. Right margin override, in pixels. (0=no override)
margin_v
Number. Right margin override, in pixels. (0=no override)
effect
String. Effect to apply to the line. (No error checking done.)
text
String. Text to display.
text_stripped
String. Same as text, but stripped for all tags, and newline/hardspace
tags are converted to real newlines/spaces. Non-hard spaces at the start/
end of lines are stripped.
karaoke
Table. Line split into karaoke syllables. See below for more information.
Note about output:
Neither text_stripped nor karaoke are used when the results are parsed, they
are only passed to simplify processing. You should set text to the final text
of the line, you want in the output.
It is encouraged to entirely leave text_stripped and karaoke out of the
tables in the result.
Karaoke tables:
A karaoke table has a number of values indexed by numbers. Each value
represents a karaoke syllable.
Key "n" holds the number of syllables. The syllables can be accessed from
index 0 and up. The syllables are indexed chronologically.
A karaoke table always has at least one syllable. The first syllable (index
0) contains all data before the first timed syllable.
Each syllable is a table containing the following keys:
duration
Number. Duration of the syllable in centiseconds. Always 0 for first
syllable.
kind
String. "Kind" of the karaoke, the name of the tag. For a \k type syllable,
kind is "k", for a \kf syllable kind is "kf". Freeform tags can be used, as
long as they start with the letter "k" or "K".
Always the empty string ("") for the first syllable.
text
String. Text of the syllable. This includes formatting tags.
For the first syllable, this contains everything before the first karaoke
timing tag.
text_stripped
String. Same as text, but with all formatting tags stripped.
Description of @config:
This is a table. The keys are the names for the options defined in the global
"configuration" table. The values are the values provided by the user.
---
Script configuration:
An automation script can provide a configuration set, allowing the user to
set certain options before the script is called.
This is performed through the "configuration" value.
Scripts can define configuration options of the following types:
label
A static, non-editable text displayed to the user. (Useful for adding
additional explanations for some options.)
text
Freeform text entry.
int
Integer numbers. A range of valid values can be specified.
float
Any kind of number. A range of valid values can be specified.
bool
A boolean on/off value.
colour
An RGB colour value.
style
The name of a style defined in the subtitles.
The "configuration" table:
The "configuration" table contains a number of values indexed by numbers.
Each value defines a configuration option.
The configuration options must be in keys numbered from 1 to n, where n
is the number of options. No "n" key is required.
The configuration options will be presented to the user in the order defined.
Each configuration option is a table containing the following keys:
name
String. The internal name used to refer to the configuration option.
Must not contain the colon or pipe characters. (ASCII 58 and 124.)
kind
String. One of "label", "text", "int", "float", "bool", "colour" and
"style". Defines what kind of option this is.
label
String. Name of the option, presented to the user. Should be very short.
hint
String. Longer description of the option, presented to the user as a
tooltip. Ignored for "label" kind options.
min
Number. Optional. Lowest value allowed. Only used for "int" and "float" kinds.
max
Number. Optional. Highest value allowed. Only used for "int" and "float" kinds.
default.
Type depends on "kind". The value given to this configuration option before
the user has entered another value. Ignored for "label" kind options.
Data types for the different kinds:
label
None. A label doesn't have a value, and won't be present in the @config
table in the process_lines function.
text
String. You might want to do some kind of extra validation on text input, as
it might be anything.
int
Number. Guaranteed to always be integer.
float
Number. Can be integer or not.
bool
Boolean.
colour
String. An ASS hex colourcode in "&HBBGGRR&" format.
style
String. The name of the style. The style can't be guaranteed to exist, as
another export filter in Aegisub might have removed it before your script
gets to run.
---
Script environment and registration:
A script is assigned to a subtitle file by adding it to the
"Automation Scripts" extra header in the [Script Info] section. This header
contains a list of script filenames, separated by pipe characters. Example:
Automation Scripts: test1.lua|test2.lua
All scripts run in their own separate interpreter. This means there is no
risk of name collisions, though also that scripts can't easily share code.
If you need to share code between several scripts, you should create a
subdirectory to the script directory, and place include files there.
The settings for the configuration options for a script are stored in the ASS
file in the following way:
Each script gets one line for configuration, named "Automation Settings" plus
a space plus the filename of the script. The filename used is stripped of all
path specifiers. (Use unique filenames for your scripts!)
The value of the line is a pipe-separated list of "name:value" pairs. The name
is the internal name given by the "name" key. It is not mangled in any way.
The way the value is stored depends on the kind of the option.
label
Not stored.
text
The string is stored in an URL-encoding like manner. Some unsafe characters
are replaced with escape-sequences of the form #xx, where xx is a two-digit
hexadecimal number for the ASCII code of the escaped character. Only ASCII-
characters can be escaped this way, Unicode characters aren't supported.
int
Stored in ASCII base 10 without any group separators.
float
Stored in exponential notation, using ASCII base 10. (As the %e sprintf()
argument.)
bool
True is stored as "1", false as "0".
colour
Stored as in ASS hex format without any mangling.
style
Stored in the same manner as "text" kind options.
---
Helper functions:
There is a gloabl variable names "aegisub". This is a table containing
various helper functions.
The following helper functions are defined:
function aegisub.set_status(text)
Sets the current status-message. (Used for progress-reporting.)
@text
String. The status message.
Returns: nothing.
function aegisub.output_debug(text)
Output text to a debug console.
@text
String. The text to output.
Returns: nothing.
function aegisub.colorstring_to_rgb(colorstring)
Convert an ASS color-string to a set of RGB values.
@colorstring
String. The color-string to convert.
Returns: Four values, all numbers, being the color components in this
order: Red, Green, Blue, Alpha-channel
function aegisub.report_progress(percent)
Report the progress of the processing.
@percent
Number. How much of the data have been processed so far. (Percent)
Returns: nothing.
function aegisub.text_extents(style, text)
Calculate the on-screen pixel size of the given text using the given style.
@style
Table. A single style definition like those passed to process_lines.
@text
String. The text to calculate the extents for. This should not contain
formatting codes, as they will be treated as part of the text.
Returns 4 values:
1: Number. Width of the text, in pixels.
2: Number. Height of the text, in pixels.
3: Number. Descent of the text, in pixels.
4: Number. External leading for the text, in pixels.
Short description of the values returned:
Width: The X advance of the text, how much the "cursor" moves forward when
this text is rendered.
Height: The total height of the text, including internal leading.
Descent: How far below the baseline a character can extend. The ascent of
the text can be calculated as (height - descent).
External leading: How much vertical spacing will be added between the lines
of text rendered with this font. The total height of a line is
(height + external_leading).
function aegisub.frame_from_ms(ms)
Return the video frame-number for the given time.
@ms
Number. Time in miliseconds to get the frame number for.
Returns: A number, the frame numer. If there is no framerate data, returns
nil.
function aegisub.ms_from_frame(frame)
Returns the start-time for the given video frame-number.
@frame
Number. Frame-number to get start-time from.
Returns: A number, the start-time of the frame. If there is no framerate
data, returns nil.
function include(filename)
Include the named script. The script search-path defined in Aegisub will be
used, searching for the script.
If the filename is relative, the regular search path will not be used, but
instead the filename will be taken as relative to the directory the current
script is located in.
Note that if you use include() inside an included script, relative paths
will still be taken relative to the original script, and not relative to the
current included script. This is a design limitation.
The included script is loaded as an anonymous function, which is executed in
the current environment. This has two implications: You can include files
based on conditional statements, and even in loops, and included files can
return values using the "return" statement.
@filename
String. Name of the file to include.
Returns: Depends on the script included.
Note that if the file couldn't be found, the script will be terminated
(or fail to load.)

<http://www.jiifurusu.dk/files/programming/effector/>
Version 2
Using Python as engine.
The first draft for an Aegisub automation engine.
Never implemented.
Version 3
Using Lua as engine.

This directory contains various Aegisub Automation scripts provided for demonstration
purposes. Most of these were originally written for testing the various functions
in Automation durings its development, but they hopefully can also serve as good
places to learn how to do things.
All of these scripts are written by Niels Martin Hansen.
They are given into the public domain, but if you use a substantial part of any of
the more advanced ones, I'd really like a bit of credit where it's due.
And remember, it's cheap to use someone else's advanced karaoke effect, especially
without any changes at all. It also gives bad karma. Like, *really* bad :)
WARNING!
DO NOT ADD YOUR OWN FILES TO THIS DIRECTORY,
they will be deleted when you uninstall/upgrade Aegisub.
This also means it's unwise to modify these files, if you want to keep your
changes to them.

without having to do programming.
You can load these scripts into an ASS file in Aegisub, and apply an effect without
doing more than writing ASS override tags.
WARNING!

-- Aegisub Automation include file
-- The purpose of this include file is to provide a default skeleton for Automation scripts,
-- where you, as a scripter, can just override the functions you need to override.
-- The following functions can be overridden:
-- do_syllable - called for each syllable in a line
-- do_line_decide - called to decide whether to process a line or not
-- do_line_start - called at the beginning of each line
-- do_line_end - called at the end of each line
-- do_line - Process an entire line
-- By default, these functions are all assigned to the following default functions
-- Your functions should obviously use the same parameter lists etc.
-- Note that if you override do_line, none of the other functions will be called!
-- All the functions mentioned here are, however, wrapped in some code that pre-calculates some
-- extra data for the lines and syllables.
-- The following fields are added to lines:
-- i - The index of the line in the file, 0 being the first
-- width - Rendered width of the line in pixels (using the line style, overrides are not taken into account)
-- height - Rendered height of the line in pixels (note that rotation isn't taken into account either)
-- ascent - Height of the ascenders, in pixels (notice that this looks like the output of text_extents?)
-- extlead - External leading of the font, in pixels (well, it is!)
-- centerleft - Pixel position of the left edge of the line, when horisontally centered on screen
-- centerright - Pixel pisition of the right edge of the line, when horisontally centered on screen
-- duration - Duration of the line in miliseconds
-- styleref - The actual style table for the style this line has
-- The following fields are added to syllables:
-- i - The index of the syllable in the line, 0 being the first (and usually empty) one
-- width, height, ascent, extlead - Same as for lines
-- left - Left pixel position of the syllable, relative to the start of the line
-- center - Center pixel position of the syllable, also relative to the start of the line
-- right - Right pixel position of the syllable, relative again
-- start_time - Start time of the syllable, in miliseconds, relative to the start of the line
-- end_time - End time of the syllable, similar to start_time
-- Return a replacement text for a syllable
function default_do_syllable(meta, styles, config, line, syl)
return syl.text
end
-- Decide whether or not to process a line
function default_do_line_decide(meta, styles, config, line)
