Stepping commands will not work until you return to f 1, but a subset of normal commands will continue to work. Changing frames with f i::Int will change the prompt to $i|debug>. It's kinda the same way just with a different GUI. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. A workaround is to use "compiled mode" which is toggled by pressing C in the debug REPL mode (note the change of prompt color). The macro is kinda the same as a breakpoint from before.

Some other packages try to fix this issue by doing some fancy magic but I'm personally a huge fan of Infiltrator.jl. The Debug: Run (Start Without Debugging) action is . Code in question. by the normal julia compiler and run just as fast as normally. At the top of the text editor we now see a toolbar with commands for common debug actions: Continue, Step over, Step Into, Step Out etc. sign in The source code preview is syntax highlighted and this highlighting has some options. I am new to Julia and so far I've had a very good experience with the VS Code Julia extension. You can use the @bp macro to do this: In order to fully support breakpoints, the debugger interprets all code, even code that is stepped over.
