The idea is to combine a Document out of many small components, then using a layouter to convert it to an easily renderable SimpleDocStream
This is an easy-to-use and lightweight text layout combinator library.
import PrettyDoc as PD
const squote = "\""
struct Block
name::String
contents::Union{String, Vector{Block}}
end
function render_block(self::Block)
if self.contents isa Vector
return PD.vsep(
PD.seg(self.name) + PD.seg("{"),
PD.vsep(map(render_block, self.contents)) >> 4,
PD.seg("}")
)
end
return PD.seg(self.name) + PD.seg(squote * escape_string(self.contents) * squote)
end
block = Block(
"A",
[
Block("C", "ccc"),
Block("B",
[
Block("C", "ccc"),
]
),
Block("C", "ccc"),
Block("C", "ccc"),
]
)
string(render_block(block))=>
A {
C "ccc"
B {
C "ccc"
}
C "ccc"
C "ccc"
}
See the API documentation for the available combinator functions.
