Forum: How to use the idbg debugger
Posted by: Ronen Kimchi
Content: 1. source the debugger codesource("idbg.R") 2. Set a breakpoint in the function to debug idbg.bp("foo") 3. Call the function foo(1,2,3) 4. The debugger will stop at the first line of foo 5. Use the following commands h - help. Print this message n - next. Empty line is the same as 'n' s - step. Step into a function o - out. Step out of a function c - continue. Continue running q - quit. Exit the debugger b - print breakpoints b <func_name> [FALSE] - set/unset a breakpoint in the first line of function b <line_number> [FALSE] - set/unset a breakpoint in current function b <func_name> <line_number> [FALSE] - set/unset a breakpoint in function at line_number w - where. Print the stack u - up. Go up the stack d - down. Go down the stack l [nlines] - list. Print nlines of source before and after current position l [nlines_back] [n_lines_forward] - list. Print source around current position x expr - execute. Evaluate expr. Any expression that doesn't match the above options will also be executed Enjoy, Ronen |
