Issue #8383 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Rejected Duplicates #6306. ---------------------------------------- Bug #8383: Ripper.lex does not handle correctly symbols whose identifiers coincide with keyword names https://bugs.ruby-lang.org/issues/8383#change-39235 Author: bozhidar (Bozhidar Batsov) Status: Rejected Priority: Normal Assignee: Category: lib Target version: ruby -v: ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.3.0] Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN This problem is best illustrated with an example [23] pry(main)> Ripper.lex(':one') => [[[1, 0], :on_symbeg, ":"], [[1, 1], :on_ident, "one"]] [24] pry(main)> Ripper.lex(':alias') => [[[1, 0], :on_symbeg, ":"], [[1, 1], :on_kw, "alias"]] I'm pretty sure that the correct tokenization of the second example should yield *:on_ident* instead of *:on_kw*. Or am I missing something? This is the behaviour on both 1.9.3 and 2.0.0. -- http://bugs.ruby-lang.org/
