Usage: break <METHOD | FILE:LINE | LINE> [if CONDITION]
break --condition N [CONDITION]
break [--show | --delete | --enable | --disable] N
break [--delete-all | --disable-all]
break
Set a breakpoint. Accepts a line number in the current file, a file and
line number, or a method, and an optional condition.
Pass appropriate flags to manipulate existing breakpoints.
Examples:
break SomeClass#run Break at the start of `SomeClass#run`.
break Foo#bar if baz? Break at `Foo#bar` only if `baz?`.
break app/models/user.rb:15 Break at line 15 in user.rb.
break 14 Break at line 14 in the current file.
break --condition 4 x > 2 Add/change condition on breakpoint #4.
break --condition 3 Remove the condition on breakpoint #3.
break --delete 5 Delete breakpoint #5.
break --disable-all Disable all breakpoints.
break --show 2 Show details about breakpoint #2.
break List all breakpoints.
