Poor's man debugger

🚧 Under development, it works but some stuff might change in the future.

The most simple way to debug your code.

This is a simple TUI debugger, it starts a local server that accepts payloads from the adapters. Everything goes through HTTP requests, so it's very fast compared to other solutions. You can think of it as a console.log(), but instead of the browser you use the terminal and it works with any language.

Requirements

• PMD-adapter for your language installed in the project.

Installation

You can install it via cargo.

1. Install cargo (https://doc.rust-lang.org/cargo/)
2. Run cargo install pmd

Configuration

The default config is located at ~/.config/pmd/config.toml (for UNIX like systems) or ~/.pmd/config.toml (for Windows).

You can override the default config by passing a -c (--config) flag that points to the config.toml file.

Keybindings

Keybindings are VIM-like. The leader key is set by default to , , but you can override this via config.

Debugger consists of three input states

• Normal
• Visual
• Inspection

Normal

Normal mode enables you to scroll all the breakpoints and callstack data.

It has the following keybindings:

• j (or Down arrow) -> Move down the list
• k (or Up arrow) -> Move up the list
• <leader> + h -> Move to the left
• <leader> + l -> Move to the right
• i -> Set inspection mode, to inspect the dumped variables
• v -> Set visual mode and open the selected breakpoint/callstack in a popup for more details.
• q -> Quit

Visual

Visual mode is meant to show additional data that are not present in normal mode for breakpoints/callstack.

It has the following keybindings:

• q -> Quit
• ESC -> Go to normal mode

Inspection

Inspection mode enables you to inspect the tree-like data that were sent by the adapters.

It has the following keybindings:

• j (or Down arrow) -> Move down the tree
• k (or Up arrow) -> Move up the tree
• h -> Close the selected item
• l -> Expand selected item.
• q -> Quit
• ESC -> Go to normal mode

Adapters

Adapters are language specific packages that sends the actual debug data to PMD via HTTP.

Currently supported

• PHP (https://github.com/nkoporec/pmd-php}

Adapter API

An example API for an adapter

curl --request POST \
  --url http://localhost:6969/dump \
  --header 'Content-Type: application/json' \
  --data '{
        "timestamp": "3223232",
        "line": "6",
        "connector_type": "php",
        "filepath": "/home/project/drupal/web/index.php",
        "callstack": [
                {
                        "filepath": "/home/project/drupal/web/index.php",
                        "line": "10"
                }
        ],
        "payload": ""
}'

Types:

• timestamp -> String
• line -> String
• connector_type -> String
• filepath -> String
• callstack -> Array (where key is a line number (int), and value is a file path (string)
• payload -> JSON encoded string
