* Keep unused literal nodesyui-knk2023-10-311-1/+1
| | | | | | | | | | | | For static analysis, it’s better to keep unused literal nodes. If simply change `block_append` to fall through, both "unused literal ignored" and "possibly useless use of a literal in void context" warnings are shown for the same line. But it’s verbose then remove "unused literal ignored" warning. This kind of optimization is already implemented on compile.c. `compile_block` calls `iseq_compile_each0` with `popped = 1` when NODE_BLOCK has next.

* skip if `DidYouMean.formatter=` is not definedKoichi Sasada2023-04-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ruby/test_default_gems.rb can define empty `DidYouMean` module because of the following line (second require) in the `lib/did_you_mean/did_you_mean.gemspec`: ```ruby begin require_relative "lib/did_you_mean/version" rescue LoadError # Fallback to load version file in ruby core repository require_relative "version" end ``` It defines only `::DidYouMean::VERSION`. However, in the `test/ruby/test_patten_matching.rb` assumes that if `defined?(DidYouMean)` is true, then there is a method `DidYouMean.formatter=` and this assumption fails all tests in `test/ruby/test_patten_matching.rb` if there is only a `::DidYouMean::VERSION`. To reproduce the failures, we need to repeat the following command: `make test-all TESTS='-v ruby/test_default_gems.rb ruby/pattern_matching'` (because the ruby/test_default_gems.rb should be run before the ruby/pattern_matching`) This patch introduces more strict gurds.

* Add pattern matching pin support for instance/class/global variablesJeremy Evans2021-07-151-0/+24
| | | | | | | | | | | Pin matching for local variables and constants is already supported, and it is fairly simple to add support for these variable types. Note that pin matching for method calls is still not supported without wrapping in parentheses (pin expressions). I think that's for the best as method calls are far more complex (arguments/blocks). Implements [Feature #17724]

* Mark pattern labels as unremoveableVladimir Dementyev2021-01-191-0/+10
| | | | | | | | | Peephole optimization doesn't play well with find pattern at least. The only case when a pattern matching could have unreachable patterns is when we have lasgn/dasgn node, which shouldn't happen in real-life. Fixes https://bugs.ruby-lang.org/issues/17534
