RubyMine lets you create breakpoints of several types. Each breakpoint type supported by RubyMine addresses different debugging needs and has its own individual settings.
Breakpoints are triggered when the program reaches the specified line of source code, before it is executed. The line of code that contains a set breakpoint, is marked with a red stripe; once such line of code is reached, the marking stripe changes to blue.
Once set, a breakpoint remains in project until removed. Breakpoints can only be set on executable lines of code. Comments, declarations of methods, and empty lines are not valid locations for breakpoints.
If a file with breakpoints has been modified externally, for example, updated from a version control repository, or changed in an external editor, so that line numbers are changed, then the breakpoints will be moved accordingly.
It is important to note that RubyMine should be running at the moment of such modification; otherwise, such changes will pass unnoticed.
In this section:
These breakpoints are assigned to lines of source code and are used to target a particular section for debugging.
Temporary line breakpoints
These breakpoints are assigned to lines of source code and are used to target a particular section for debugging. When hit, such breakpoints are immediately removed.
Exception breakpoints are triggered when the specified exception is thrown. Unlike the line breakpoints, which require specific source references, exception breakpoints apply globally to the exception condition, rather than to a particular code reference.
