;;; Commentary:
;; Dape is a debug adapter client for Emacs. The debug adapter
;; protocol, much like its more well-known counterpart, the language
;; server protocol, aims to establish a common API for programming
;; tools. However, instead of functionalities such as code
;; completions, it provides a standardized interface for debuggers.
;; To begin a debugging session, invoke the `dape' command. In the
;; minibuffer prompt, enter a debug adapter configuration name from
;; `dape-configs'.
; For complete functionality, make sure to enable `eldoc-mode' in your
; source buffers and `repeat-mode' for more pleasant key mappings.
;; Package looks is heavily inspired by gdb-mi.el

"This variable holds the dape configurations as an alist.
In this alist, the car element serves as a symbol identifying each
configuration. Each configuration, in turn, is a property list (plist)
where keys can be symbols or keywords.
Symbol keys (Used by dape):
- fn: Function or list of functions, takes config and returns config.
If list functions are applied in order.
See `dape-default-config-functions'.
- ensure: Function to ensure that adapter is available.
- command: Shell command to initiate the debug adapter.
- command-args: List of string arguments for the command.
- command-cwd: Working directory for the command, if not supplied
`default-directory' will be used.
- prefix-local: Path prefix for Emacs file access.
- prefix-remote: Path prefix for debugger file access.
- host: Host of the debug adapter.
- port: Port of the debug adapter.
- modes: List of modes where the configuration is active in `dape'
completions.
- compile: Executes a shell command with `dape-compile-fn'.
Connection to Debug Adapter:
- If command is specified and not port, dape communicates with the
debug adapter through stdin/stdout.
- If host and port are specified, dape connects to the debug adapter.
If command is specified, dape waits until the command initializes
before connecting to host and port.
Keywords in configuration:
Keywords (symbols starting with colon) are transmitted to the
adapter during the initialize and launch/attach requests. Refer to
`json-serialize' for detailed information on how dape serializes
these keyword elements. Dape uses nil as false.
Functions and symbols:
- If a value is a function, its return value replaces the key's
value before execution. The function is called with no arguments.
- If a value is a symbol, it resolves recursively before execution."
