debug.lua: a terminal based debugger for lua
What is it?
debug.lua is a terminal based standalone frontend for mobdebug. Because it is terminal based, it is navigated only with the keyboard, but it does feature source navigation and a display for expressions that change as you step through the source.
It has been tested on Linux and Mac OS X with lua 5.1, 5.2 and 5.3. The debuggee can be anything that is supported by mobdebug.
What's new in version 0.11
- added simple config files to change the colors used by debug.lua
- fixed a bug where the output of the ‘=’ command was getting formatted on a weird (and also wrong) way
What's new in version 0.10
- fixed bug where last line in a source file would not be read if it did not end in a newline
- added conditional breakpoints
- when called with `-l file` argument, debug.lua will now also log all pinned expressions to the output log whenever they're updated.
- fixed number lexing bug in loader.lua
- fixed short string lexing bug in loader.lua
- fixed error "handling" in loader.lua
- added D command as interface to mobdebugs `DONE` command
- read default port from environment var MOBDEBUG_PORT if it exists
- added check for required mobdebug version (currently 0.63 or later)
If you want to know a little more, you can check out the original mobdebug documentation and code.
There is also a mercurial repository at https://codeberg.org/gnarz/debug.lua which gets changes I make between the releases.
debug.lua module and all accompanying documentation and additional source code is released under the MIT license.
