4c: Tank Printer
++re
Pretty-printing engine
Pretty-printing engine that accepts a ++tank sample and contains arms that perform computation on it.
Accepts
tac is a ++tank.
Produces
++ re |_ tac/tank
Examples
> ~(. re leaf+"ham")
<2.gdc {tac/{$leaf ""} <402.arm 110.jyx 1.ztu $151>}>
++ram:re
Flatten to tape
Flatten ++tank out into a ++tape.
Accepts
tac is a ++tank, taken from sample of ++re core.
Produces
A ++tape.
Source
++ ram ^- tape ?- -.tac $leaf p.tac $palm ram(tac [%rose [p.p.tac (weld q.p.tac r.p.tac) s.p.tac] q.tac]) $rose %+ weld q.p.tac |- ^- tape ?~ q.tac r.p.tac =+ voz=$(q.tac t.q.tac) (weld ram(tac i.q.tac) ?~(t.q.tac voz (weld p.p.tac voz))) == ::
Examples
> ~(ram re leaf+"foo")
"foo"
> ~(ram re rose+["." "(" ")"]^~[leaf+"bar" leaf+"baz" leaf+"bam"])
"(bar.baz.bam)"
++win:re
Render at indent
Render at indent level tab and width edg.
Accepts
tac is a ++tank, taken from sample of ++re core.
tab and edg are atoms.
Produces
A ++wall (++list of ++tapes).
