This is the command zshdb that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
zshdb - zsh debugger
SYNOPSIS
zshdb [options] [--] script-name [script options]
zshdb [options] -c execution-string
DESCRIPTION
"zshdb" is a zsh script to which arranges for another zsh script to be debugged. The
debugger has a similar command interface as gdb(1).
If you used zshdb script and need to pass options to the script to be debugged, add "--"
before the script name. That will tell zshdb not to try to process any further options.
OPTIONS
-h | --help
Print a usage message on standard error and exit with a return code of 100.
-A | --annotation level
Sets to output additional stack and status information which allows front-ends such as
emacs to track what's going on without polling.
This is needed in for regression testing. Using this option is equivalent to issuing:
set annotation LEVEL
inside the debugger.
-B | --basename
In places where a filename appears in debugger output give just the basename only.
This is needed in for regression testing. Using this option is equivalent to issuing:
set basename on
inside the debugger.
-n | --nx | --no-init
Normally the debugger will read debugger commands in "~/.zshdbinit" if that file
exists before accepting user interaction. ".zshdbinit" is analogus to Perl's
".perldb" or GNU gdb's ".gdbinit": a user might want to create such a debugger profile
to add various user-specific customizations.
Using the "-n" option this initialization file will not be read. This is useful in
regression testing or in tracking down a problem with one's ".zshdbinit" profile.
-c | --command command-string
Instead of specifying the name of a script file, one can give an execution string that
is to be debugged. Use this option to do that.
-q | --quiet
Do not print introductory version and copyright information. This is again useful in
regression testing where we don't want to include a changeable copyright date in the
regression-test matching.
-x | --eval-command debugger-cmdfile
Run the debugger commands debugger-cmdfile before accepting user input. These
commands are read however after any ".zshdbinit" commands. Again this is useful
running regression-testing debug scripts.
-L | --library debugger-library
The debugger needs to source or include a number of functions and these reside in a
library. If this option is not given the default location of library is relative to
the installed zshdb script: "../lib/zshdb".
-T | --tempdir temporary-file-directory
The debugger needs to make use of some temporary filesystem storage to save persistent
information across a subshell return or in order to evaluate an expression. The
default directory is "/tmp" but you can use this option to set the directory where
debugger temporary files will be created.
-t | --tty tty-name
Debugger output usually goes to a terminal rather than stdout or stdin which the
debugged program may use. Determination of the tty or pseudo-tty is normally done
automatically. However if you want to control where the debugger output goes, use this
option.
-V | --version
Show version number and no-warranty and exit with return code 1.
