}Type of a element in a matrix of styled characters.
Type of a matrix of points. The matrix is indexed by lines then columns, i.e. to access the point at line l and column c in matrix m you should use m.(l).(c).
matrix size creates a matrix of the given size containing only blank characters.
set_style point style sets fields of point according to fields of style. For example:
set_style point { LTerm_style.none with LTerm_style.bold = Some true }will have the following effect:
point.bold <- trueType of contexts. A context is used for drawing.
context m s creates a context from a matrix m of size s. It raises Invalid_argument if s is not the size of m.
Exception raised when trying to access a point that is outside the bounds of a context.
size ctx returns the size of the given context.
sub ctx rect creates a sub-context from the given context. It raises Out_of_bounds if the rectangle is not contained in the given context.
clear ctx clears the given context. It resets all styles to their default and sets characters to spaces.
fill ctx ch fills the given context with ch.
fill_style style fills the given context with style.
point ctx row column returns the point at given position in ctx. It raises Out_of_bounds if the coordinates are outside the given context.
draw_char_matrix matrix row column ?style ch sets the character at given coordinates to ch. It does nothing if the given coordinates are outside the bounds of the context.
draw_char ctx row column ?style ch sets the character at given coordinates to ch. It does nothing if the given coordinates are outside the bounds of the context.
draw_string ctx row column ?style str draws the given string at given coordinates. This does not affect styles. str may contains newlines.
draw_styled ctx row column ?style text draws the given styled text at given coordinates.

Type of an connection in a piece that can be connected to other pieces.
Type of a piece, given by its four connection.
Draws a piece. It may modify pieces around it.
draw_hline ctx row column length connection draws an horizontal line.
draw_hline ctx row column length connection draws a vertical line.
Draws a rectangle.

Zed_string.t ->
connection ->
unitDraws a rectangle with a label on the top row.
