SYSL-Text

Please see the "main.lua" for samples, please review the library for all the possible tags.

Update Notes

New [scroll] command, will scroll the text up by line-height or a set value. Works well with love.graphics.setScissor.
You have access to the basic calculated width, height and linecount for each textbox. Access is under the get table.
- my_cool_textbox.get.width, my_cool_textbox.get.height, my_cool_textbox.get.lines
- If you are using autowrap, the width calculation is more accurate.
Text animation commands now allow you to change the speed, or even reverse it.
It is no longer required to wrap UTF8 characters. You can send them without the wrapping and the library will scan and wrap extended characters without any manual input.

Setup

Adding the library to your project

-- Require the library in your project
Text = require(text.lua)

Create your first textbox

-- Require the library in your project
my_cool_textbox = Text.new()

Apply text to your textbox

-- Require the library in your project
my_cool_textbox:send("Oh, gee, I hope this print out one by one!")

Let love2d know to draw your textbox

-- in love.draw()
-- my_cool_textbox:draw(x,y)
my_cool_textbox:draw(0,0)

Let love2d know to update your textbox

-- in love.update(dt)
my_cool_textbox:update(dt)

Tags

SYSL-Text supports tags in [these brackets] and will use them to apply effects to your rendered text. SYSL-Text also supports defining default styles per textbox. Please take a look at the examples below. Please note that effects and style are only examples, the library does not provide backgrounds or textboxes.

Textbox Information

Width, Height, Lines

You can get the width, height and the number of lines after sending text to a textbox.

my_cool_textbox = Text.new()

my_cool_textbox:send("Oh, gee, I hope this print out one by one!")
local textbox_x = 0
local textbox_y = 0
local textbox_w = my_cool_textbox.get.width
local textbox_h = my_cool_textbox.get.height
local textbox_l = my_cool_textbox.get.lines
-- in love.draw()
love.graphics.rectangle("fill", textbox_x, textbox_y, textbox_w, textbox_h)
my_cool_textbox:draw(textbox_x, textbox_y)

is_finished()

Returns true if the textbox is done printing, or false if the textbox is still printing.

It will also return as true if [waitforinput] is in the text string.

are_you_done = my_cool_textbox:is_finished()

continue()

Continue will continue printing after [waitforinput] pauses it.

-- You only need to send this once.
my_cool_textbox:continue()

Tag Notes

Some tags will not work until you let the library know something about your game.

Audio

--Text.configure.audio_table(table_string)
Text.configure.audio_table("Audio")

This configuration item will pass along the Lua table you are using to store audio sources. It currently can search down one level from that base table.

Enables "[audio]": Starts playing an audio source.
Used like: "[audio=guy-laughing]" or "[audio=music=level1]"

Enables "[/audio]": Stops playing an audio source.
Used like: "[/audio=guy-laughing]" or "[/audio=music=level1]"

Audio-Sound per character

--Text.configure.add_text_sound(sound, volume) 
Text.configure.add_text_sound(Audio.text.default, 0.2)

This will allow you to add voices so textboxes will jabber at you as they print characters. Note that the following commands will not work until you set up this configuration.

Enables: 
"[voice=#]": Set the speaking voice, 0 will turn it off.
"[warble=#]": Set the pitch varience, +/- on the voice.
"[/warble]": Stops the pitch varience.
"[soundevery=#]": How often does a sound play per character.
"[/soundevery]": Reset the sound per character.

Used like: "[voice=2][warble=3][soundevery=1]I'm talking really fast and making a lot of noise![voice=0][/warble][/soundevery]"

Fonts

--Text.configure.font_table(table_string)
Text.configure.font_table("Font")

This configuration item will pass along the Lua table you are using to store your Font sources.

Enables "[font=Font.name]": Set the font.
Used like: "[font=Font.ComicSansMs]" or "[font=Font.default]"

Enables "[/font]": Set the font back to the textbox default.
Used like: "[/font]"

Images

--Text.configure.image_table(table_string)
Text.configure.image_table("img")

This configuration item will pass along the Lua table you are using to store image sources. It currently can search down one level from that base table.

Enables "[image=name]": Draw an image inline with the text.
Used like: "[image=skull]" or "[image=ui=skull]

Icons

--Text.configure.icon_table(table_string)
Text.configure.icon_table("Icon")

This configuration item will pass along the Lua table you are using to hold an icon drawing library. Note that this function assumes your library has a .draw() and .count() available. .draw() would work similar to how love.graphics.draw() works, with the source being replaced by a number. .count() would just return the number of available icons. If you would prefer to just use images, you can leave this configuration out and use the "[image]" tag.

Enables "[icon=#]": Draw an icon inline with the text.
Used like: "[icon=1]

Palettes

--Text.configure.palette_table(table_string)
Text.configure.palette_table("Palettes")

This configuration item will pass along the Lua table you are using to hold an indexed list of palettes. You can then use this prebuilt index instead of "[color=#hexval]".

Enables "[color=#]": Changed the color of the text based on a palette list.
Used like: "[color=1]

Shader Effects

--Text.configure.shader_table(table_string)
Text.configure.shader_table("Shaders")

This configuration item will pass along the Lua table you are using to hold shader functions you have created. These shader functions can be then applied directly to the text.

Enables "[shader=name]": Apply effects on text from a shader.
Used like: "[shader=blur]

Scripting Commands

--Text.configure.function_command_enable(enable_bool)
Text.configure.function_command_enable(enable_bool)

This nightmare will allow you to write direct lua code into a string to execute. It's off by default. Please be careful when using. Do not use unless you sandbox your text.
