754a9369db
Added a new "interpreter" properties to encapsulate any properties for the command interpreter. Right now this contains only "expand-regex-aliases", so you can now enable (disabled by default) the echoing of the command that a regular expression alias expands to: (lldb) b main Breakpoint created: 1: name = 'main', locations = 1 Note that the expanded regular expression command wasn't shown by default. You can enable it if you want to: (lldb) settings set interpreter.expand-regex-aliases true (lldb) b main breakpoint set --name 'main' Breakpoint created: 1: name = 'main', locations = 1 Also enabled auto completion for enumeration option values (OptionValueEnumeration) and for boolean option values (OptionValueBoolean). Fixed auto completion for settings names when nothing has been type (it should show all settings). llvm-svn: 162418
