# Windon't
### A replacement for the Window API, created by someone who can't think of better names
To load Windon't, simply use `require` or `dofile`.
```lua
local windont = dofile("path/to/windont.lua")
```
Windon't contains two functions: one to make a new window object, and another to render them.
Beyond that, Windon't stores various default values that are used when creating new windows.
```lson
windont.default = {
baseTerm = term.current(), -- default base terminal for all windows
textColor = "0", -- default text color (what " " corresponds to in term.blit's second argument)
backColor = "f", -- default background color (what " " corresponds to in term.blit's third argument)
blink = true, -- default getCursorBlink
visible = true, -- default whether or not new windows are visible
alwaysRender = true, -- if true, new windows will always render if they are written to
}
```
### windont.newWindow
```
windont.newWindow(number x, number y, number width, number height, table miscData)
```
Creates a new window located at (`x`, `y`), with the specified `width` and `height`.
By default, the base terminal used will be `windont.default.baseTerm`, which is normally set to `term.current()`.
"Windon'ts" naturally can be used with `term.redirect`, but they also come with a `meta` value which contains all the information of the object, including cursor X and Y, width and height, the whole framebuffer, the cursor blinking, and more.
Windon't windows behave very similarly to regular ol' Window API windows, with a few differences. For one, **Windon't windows support transparency when drawing over one another**.
Secondly, **Windon'ts support the use of individual transformation functions for characters, text colors, background colors, and the whole meta function.** Transformation functions are, if given, called every time the window is rendered. More on that later.
Additional values can be given to the newly created window through the `miscData` argument, including the base terminal and visibility.
Here are all the values that you can set by default with `miscData`:
```
buffer
renderBuddies -- table, a list of other windon't objects that will render beneath this one every time this redraws
baseTerm -- window, the terminal that this windon't object will render onto
isColor
charTransformation -- function, ran on every X and Y on the window's base temrinal, I'll explain in a bit
textTransformation -- function, in a bit
backTransformation -- function, in a bit
metaTransformation -- function, takes in the 'meta' value of a windon't object so it can be modified
cursorX -- number, starting cursor X
cursorY -- number, starting cursor Y
textColor -- string, starting text color ("0" through "f", or "-"" for transparency)
backColor -- string, starting background color (same range as textColor)
blink -- boolean, cursor blinking
alwaysRender -- boolean, if true, then all term.write or term.blit calls will immediately render to the base temrinal
visible -- boolean, if false, then the window just like, won't render, man
```
All transformation functions (except for `metaTransformation`) are called on every (x, y) position on the screen per window, and each one takes in three arguments:
1. X position on the screen relative to the window's X position
2. Y position on the screen relative to the window's Y position
3. `meta` value of the window
and return the following information:
1. New X position for that part of the window
2. New Y position for that part of the window
3. Optionally, a new character, text color, or background color (depending on if it's `charTransformation`, `textTransformation`, or `backTransformation`.)
`metaTransformation` is different in that it takes one value, being the window's `meta` value, and returns nothing. The `metaTransformation` function just modifies the `meta` value and that's it.
As a side note, the order that the transformations are called in is as follows:
1. metaTransformation
2. charTransformation
3. textTransformation
4. backTransformation
<<< MORE ON THAT LATER >>>
## windont.render
```
windont.render(optional number x1, optional number x2, optional number y, winodw_1, window_2, ...)
```
Renders one or more Windon't objects onto their base terminals. If two or more windows share a base terminal, they will render layered atop each other from top to bottom, meaning that `window_1` will draw on top of `window_2`.
If windows contain any transparent regions (designated by the color "-" usable with `term.blit`), then the next window down the list will peek through.
Transparency is applied individually for text colors and background colors. If you have a window with a solid BG color but a transparent text color, then the background color of the underlying window will now be the text color of the above window, kinda like a text-shaped stencil.
The optional values `x1`, `x2`, and `y` are used if you want to render to only render onto a specific line on the base terminal (specifically, line `y` from X `x1` to `x2`).
If a window's meta has `alwaysRender = true`, then `windont.render` is called with that window, as well as the positions of the write/blit call.
