From: mame@... Date: 2019-12-03T00:14:30+00:00 Subject: [ruby-core:96064] [Ruby master Bug#16389] Unexpected tINTEGER in conditional expression Issue #16389 has been updated by mame (Yusuke Endoh). Status changed from Open to Closed You need to parenthesize the argument 15. ``` foo unless (@bar&.nil? && @baz&.>(15)) ``` I don't think that your expectation is wrong, but due to parser limitation, we cannot place a non-parenthesized method call as an argument of `&&`. It is a good practice to write parentheses for method calls, except some trivial cases (e.g., no-argument method calls and `p arg`). ---------------------------------------- Bug #16389: Unexpected tINTEGER in conditional expression https://bugs.ruby-lang.org/issues/16389#change-82910 * Author: codinganarchy (Matthew Tanous) * Status: Closed * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.6.4p104 (2019-08-28 revision 67798) [x86_64-darwin18] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- I'm not sure that this is a bug, or simply an unexpected result of operator precedence, but I am seeing a result that appears to me to be an issue. When putting a conditional expression after a command call using `unless`, I am seeing a syntax error when I believe the syntax should be valid. In particular: ```ruby def foo puts "This method just has to exist" end foo unless (@bar&.nil? && @baz&.> 15) ``` This produces`syntax error, unexpected tINTEGER, expecting ')'` following the `&.>` safe navigation. I would not expect a syntax error here. This seems a strange result to me, as `foo unless (@bar&.nil? and @baz&.> 15)` appears to work as expected, producing no syntax error. Please let me know if I am missing something in either my expectation or the issue report. Thanks! -- https://bugs.ruby-lang.org/ Unsubscribe:
