Well const_get('Foo') is syntactically a non-constant while const_get('Foo')::Bar is. This is the ultimate reason why working_meta works but failing_meta fails. If you want to meta-program you have to be explicit like const_get('Foo').module_eval { ... }. ---------------------------------------- Bug #13623: meta-programming, adding sub-module fails with syntax error https://bugs.ruby-lang.org/issues/13623#change-65237 * Author: caschip (Aad Schippers) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux] * Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN ---------------------------------------- The goal is to add a sub-module to a higher level module. The higher level module is derived from its name in a string. This works in one case and gives an unexpected syntax error in another case. failing_meta:4: syntax error, unexpected '\n', expecting &. or :: or '[' or '.' failing_meta:8: syntax error, unexpected keyword_end, expecting end-of-input ---Files-------------------------------- no_meta (72 Bytes) working_meta (82 Bytes) failing_meta (95 Bytes) -- https://bugs.ruby-lang.org/ Unsubscribe:
