Karaoke [Inline-FX]

Here is a timed karaoke line with inline-fx markup:

{\k40}zu{\k20}t{\k42}to {\k32\-paint}e{\k17}ga{\k45}i{\k32}te{\k26}ta {\k24\-cloud}yu{\k55}me

These syllables get inline-fx assigned like this:

With the sample timed karaoke from above, you could have the following templates:

template syl: {base effect applied for all syllables}
template syl fx paint: {overlay effect applied only to the 'paint' syllables}
template syl fx cloud: {overlay effect applied only to the 'cloud' syllables}

The idea here is to have a base effect and then some of the syllables get some more effects on top of that.

It is possible to match only syllables with blank inline-fx in kara-templater by using an fxgroup that enables or disables basing on inline-fx. You can also use _fxgroup_s to have templates that run for multiple inline-fx.

code syl: fxgroup.blankfx = (syl.inline_fx == "")
template syl fxgroup blankfx: {effect only applied on blank inline-fx syllables}

The important thing is that the code line runs per syllable and runs before any per-syllable templates that must use it.

In some code that runs per-syllable in your script:

if syl.inline_fx == "" then
    apply_base_effect(subs, meta, line, syl)
elseif syl.inline_fx == "paint" then
    apply_paint_effect(subs, meta, line, syl)
elseif syl.inline_fx == "cloud" then
    apply_cloud_effect(subs, meta, line, syl)
end

Simply compare the inline-fx name to the various possibilities and run the right effect code.

In some code that runs per-syllable in your script: At top-level of your script:

effects = {}
effects[""] = function(subs, meta, line, syl)
    -- base effect code here
end
effects.paint = function(subs, meta, line, syl)
    -- paint effect code here
end
effects.cloud = function(subs, meta, line, syl)
    -- cloud effect code here
end

Then later, in some per-syllable processing code:

effects[syl.inline_fx](subs, meta, line, syl)

First, a table is created and filled with functions for applying the different effects. The keys used for the table are the names of the possible inline-fx. When the effect has to be applied, the right function is looked up in the effect table and then called.
