From: daniel@...42.com Date: 2020-04-13T17:37:27+00:00 Subject: [ruby-core:97869] [Ruby master Feature#16688] Allow #to_path object as argument to system() Issue #16688 has been updated by Dan0042 (Daniel DeLorme). There's maybe just one small gotcha to consider: ```ruby o = File.open("o","w") system("ls", out: o) #should be equivalent system("ls", out: o.fileno) #to this system("ls", out: o.to_path) #not to this ``` ---------------------------------------- Feature #16688: Allow #to_path object as argument to system() https://bugs.ruby-lang.org/issues/16688#change-85093 * Author: Dan0042 (Daniel DeLorme) * Status: Open * Priority: Normal ---------------------------------------- I often work with Pathname objects, but when passing them to a system command I find it a bit tedious that they have to be explicitly converted to a String. ```ruby file = BASE + "config.json" system(@cmd, file) #=> TypeError (no implicit conversion of Pathname into String) system(@cmd, file.to_s) #=> works ``` I propose that the system/exec/spawn family of methods should try to convert their arguments using `to_path`, if `to_str` fails. I believe it makes perfect sense, since commandline arguments are so often pathnames. This includes in/out redirection. `system("ls", out: Pathname.new("file"))` should be valid. -- https://bugs.ruby-lang.org/ Unsubscribe:
