Interactive Xdebug step-debugging client for your terminal.

• Travel forwards: step over, into and out.
• Travel backwards: it's not quite time travel - but you can revisit and inspect previous steps in history mode.
• Jump the stack: jump up and down the stack.
• Vim-like motions: Typing 100n will repeat "step into" 100 times.
• Inline values: Show variable values inline with the source code.
• Process control: Launch, monitor and restart the process being debugged.

• Download the latest release.
• Compile it yourself cargo build.

• --log: Debug log to file.
• --listen: Listen on an alternative address (defaults to 0.0.0.0:9003).

In addition you can optionally specify a process to debug:

$ debug-tui -- php path/to/script.php

Prefix with number to repeat:

• r run
• n next / step into
• N step over
• p previous (switches to history mode if in current mode)
• o step out
• R restart process if one was provided
• j down
• J down 10
• k up
• K up 10
• h left
• H left 10
• l right
• L right 10
• + increase context depth
• - decrease context depth
• tab switch pane
• enter toggle pane focus (full screen)
• t rotate the theme
• ? Show help
• f Filter (context pane) - use dot notation to filter on multiple levels.

debug-tui has no mechanism for setting a breakpoint but you can use the function xdebug_break() in your code:

<?php

function my_function() {
    xdebug_break(); // break after this line
}
