Parse a text message into command and arguments (Whapi helper)

Source: R/webhook.R
whapi_parse_command.Rd

Splits an incoming text (usually from a WhatsApp message) into a command (the first token, starting with /) and its associated arguments. Supports collapsing arguments into a single string or preserving them as a character vector.

Usage

whapi_parse_command(text, collapse_args = TRUE)

Arguments

text

A character string containing the full message (e.g. "/groe ajuda").

collapse_args

Logical, default TRUE. If TRUE, all arguments are collapsed into a single space-separated string. If FALSE, arguments are returned as a character vector of tokens.

Value

A list with two elements:

command

The command string (first token), trimmed (e.g. "/groe").

arguments

The arguments, either collapsed as a single string (default) or as a character vector, depending on collapse_args.
