fmt — an optimal pretty-printer / formatter for LFE Copyright 2026 Duncan McGreggor and contributors This product includes software derived from LFE (Lisp Flavoured Erlang). src/pe_lfe_scan.erl is derived from lfe_scan.erl Copyright Robert Virding Licensed under the Apache License, Version 2.0 https://github.com/lfe/lfe The original lfe_scan.erl is a continuation-passing, character-list LFE scanner. pe_lfe_scan.erl adapts its scanning clauses to operate on a binary, to keep line+column positions on every token, and to emit comments as trivia tokens rather than discarding them. The surface grammar (symbols, numbers, strings, based numbers, characters, hash forms, and comments) is ported from lfe_scan; see the per-clause attributions in the module.
