Its goal is to provide all the niceties of modern GUI-based debuggers in a
more lightweight and keyboard-friendly package. PuDB allows you to debug code
right where you write and test it--in a terminal.

Features
-
Syntax-highlighted source, the stack, breakpoints and variables are all
visible at once and continuously updated. This helps you be more aware of
what's going on in your program. Variable displays can be expanded, collapsed
and have various customization options. -
Pre-bundled themes, including dark themes via "Ctrl-P". Could set a custom theme also.
-
Simple, keyboard-based navigation using single keystrokes makes debugging
quick and easy. PuDB understands cursor-keys and Vi shortcuts for navigation.
Other keys are inspired by the corresponding pdb commands. -
Use search to find relevant source code, or use "m" to invoke the module
browser that shows loaded modules, lets you load new ones and reload existing
ones. -
Breakpoints can be set just by pointing at a source line and hitting "b" and
then edited visually in the breakpoints window. Or hit "t" to run to the line
under the cursor. -
Drop to a Python shell in the current environment by pressing "!".
Or open a command prompt alongside the source-code via "Ctrl-X". -
PuDB places special emphasis on exception handling. A post-mortem mode makes
it easy to retrace a crashing program's last steps. -
Ability to control the debugger from a separate terminal.
-
IPython integration (see
wiki <http://wiki.tiker.net/PuDB>_) -
Should work with Python 3.6 and newer. (Versions 2019.2 and older continue
to support Python 2.7.)
