![]() ![]() The effect itself is these small swords dropping down onto the syllables, by a move. The drawing is of a small simple sword pointing downwards. The first code line defines a vector drawing shape for convenience, so it doesn’t clutter up the actual template lines later on. “code once” lines are primarily intended to declare functions for use in templates. They are run in the order they are declared. This class modifier is only valid for code lines.Ĭode lines with the once modifier are run exactly once during Karaoke Templater execution, and are always run before any other code lines or templates. Having one is still recommended for clarity, however.Ī template line without a class modifier is implicitly given the syl modifier.Ī code line without a class modifier is implicitly given the once modifier. Class declaring modifiers #īoth template lines and code lines can be produced without having a class modifier. There is a special set of modifiers that declare the class of the template line or code line. While modifiers can be combined to some extent, not all are compatible, and not all work on both code lines and for templates. This is a space-separated list of words in the Effect field following the template or code keyword. Miscellaneous APIs for e.g.Template lines and code lines can take a number of modifiers. Providing a configuration interface for export filters. Displaying dialogue boxes and getting user input requesting user input during macro execution by dialogue boxes and Hints and warnings to the user and printing debug information. Progress reporting and debug output providing feedback to the user while a script is running, outputting Subtitle file interface Deals with use of the subtitles object, the principal way of accessingĪnd modifying the subtitle data. Script and feature registration Deals with advertising what features a script provides and a few other The Automation 4 Lua core API #Īutomation 4 Lua provides various APIs that can be grouped in these generalĬategories. Of the functions provided by the includes. You will find that for anything but the simplest scripts you will need some While it is possible to writeĪutomation 4 Lua scripts without using the provided standard include files that don’tĭepend directly on Aegisub internal data structures, have been implemented Most things that can be implemented in clean Lua code, i.e. Piece of text will be when rendered with a given style. the video frame timestamps and how large a This is described on the Subtitle file interface page.Īutomation 4 Lua also provides a number of helper functions in the core APIįor getting information on e.g. The subtitles object allows you to accessĮvery line in the subtitle file, including headers, style definitions,ĭialogue lines and comment lines. ![]() Integer-indexed array, but it exposes some special interfaces to add, To some extent, the subtitles object works as an Object, the primary interface to the subtitle data the script will One of the parameters passed to the function is a subtitles Selecting a macro from the Automation menu) the registered script function When the user activates a feature from the Aegisub interface (such as by Lua_automation_version and the registration functions. The only fields of theĪegisub object that should be touched during script loading are Then call the feature registration functions. Import some modules, write some functions that do the script’s work and What you usually will do is define some of the script information globals, You can put variable initialisations and such at the top level, but When an Automation 4 Lua script is loaded, its top-level code is executed Templater script defines one macro and one export filter. Zero, one or many of each of those features. This information will be displayed in theĪutomation/Manager window: script_name, script_description,Īutomation 4 Lua implements both of the currently defined “features” ofĪutomation 4: Macro and Export Filter. There’s a number of global variables a script can set to provide The smallest legal Automation 4 Lua script is an empty file, but that won’t General overview of the organisation of Automation 4 Lua # Language itself and its standard libraries.
