From: merch-redmine@... Date: 2020-06-12T16:07:00+00:00 Subject: [ruby-core:98766] [Ruby master Bug#16957] Documentation example for enum.chunk doesn't match actual output. Issue #16957 has been updated by jeremyevans0 (Jeremy Evans). The existing example code assumes the words in `/usr/share/dict/word` will be already upcased, which isn't true in your case (MacOS) and looks like it isn't true in my case either (OpenBSD). I think your patch is a good way to handle the issue; I'll merge it shortly. ---------------------------------------- Bug #16957: Documentation example for enum.chunk doesn't match actual output. https://bugs.ruby-lang.org/issues/16957#change-86123 * Author: CryptoRAT (Luke Elliot) * Status: Open * Priority: Normal * ruby -v: ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- I was experimenting with chunk, ruby 2.7.1, using the documentation sample, also 2.7.1: ``` ruby open("/usr/share/dict/words", "r:iso-8859-1") { |f| f.chunk { |line| line.ord }.each { |ch, lines| p [ch.chr, lines.length] } } #=> ["\n", 1] # ["A", 1327] # ["B", 1372] # ["C", 1507] # ["D", 791] # ... ``` While doing this noticed that my output was significantly different. ``` ruby #=> ["A", 1] # ["a", 5] # ["A", 1] # ["a", 2] # ["A", 7] # ... ``` I am fairly new to ruby, though not to programming. I played around some and found that by using line.upcase.ord I can get something more like what was expected, minus the '\n'. ``` ruby open('/usr/share/dict/words', 'r:iso-8859-1') { |f| f.chunk { |line| line.upcase.ord }.each { |ch, lines| p [ch.chr, lines.length] } } #=> ["A", 17096] # ["B", 11070] # ["C", 19901] # ["D", 10896] ``` This can be fixed by either updating the doc to show the actual output or update the code to make align the output with the code. I have a patch I will attach as I go through the documentation on how to do that in this project. I also opened a ticket on github, perhaps in error. https://github.com/documenting-ruby/ruby/issues/93 ---Files-------------------------------- 00093.patch (1.17 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
