![]() ![]() ![]() Note that R is used to restart the operation(no need quit and start debugger again).ĭebugged program terminated. For example, create the file called “debug_cmds” with the perl debug commands as, Perl debugger can get the debug command from the file and execute it. Get debug commands from the file (source) Perl Debugger Quick Reference by Richard Foley Perl’s debugger is powerful but somewhat esoteric. the debugger will load breakpoints against the current file and it's project files, when it is load by the perl debug program, if you get it wrong, just adjust breakpoints as you go with bB or quit and adjust breakpoints with panel and then re-run. perl-debugger perl-maintenance tracing Many people who work with Perl code never touch the debugger. Use o inhibit_exit to avoid stopping after program termination,Īfter the last continue operation, the output gets printed on the stdout as “./perl_” since it matches the pattern “perl”. Main::(./perl_:44): print join cĭebugged program terminated. Print the value in the specific variable using (p) Continue down to the specific line number using (c)ģ6: return 9. Continue till next breakpoint (or line number, or subroutine) using (c)Ģ2: my $pattern = shift 8. A (very) lightweight introduction in the use of the perl debugger, and a pointer to existing, deeper sources of information on the subject of debugging perl. The s option does stepping into the subroutine but while n option which would execute the subroutine(stepping over it). Option n executes the subroutine in a single step (stepping over it). In Perl, the debugger is not a separate program the way it usually is in the typical compiled environment. Option s and n does step by step execution of each statements. My goal in this article is to provide reasoned argument for adding the Perl debugger to your set of tools, as well as pointers on how to do Read it. View the breakpoints using (L)Ĥ4: print join if (1) 6. Many people who work with Perl code never touch the debugger. Set the breakpoint on specific line using (b)ĭB b 44 5. Among the many remarkable features of the perl interpreter, not the least of them is the full-featured source level debugger. Set the breakpoint on get_pattern function using (b)ĭB b find_files 4.
