This printer is a fork of recast's printer with its algorithm replaced by the one described by Wadler in "A prettier printer". There still may be leftover code from recast that needs to be cleaned up.
The basic idea is that the printer takes an AST and returns an intermediate representation of the output, and the printer uses that to generate a string. The advantage is that the printer can "measure" the IR and see if the output is going to fit on a line, and break if not.
This means that most of the logic of printing an AST involves
generating an abstract representation of the output involving certain
commands. For example, concat(["(", line, arg, line ")"]) would
represent a concatenation of opening parens, an argument, and closing
parens. But if that doesn't fit on one line, the printer can break
where line is specified.
More (rough) details can be found in commands.md.
