Function: eshell-parse-command-input

eshell-parse-command-input is a byte-compiled function defined in esh-mode.el.gz.

Signature

(eshell-parse-command-input BEG END &optional ARGS)

Documentation

Parse the command input from BEG to END.

The difference is that eshell-parse-command expects a complete command string (and will error if it doesn't get one), whereas this function will inform the caller whether more input is required.

If nil is returned, more input is necessary (probably because a multi-line input string wasn't terminated properly). Otherwise, it will return the parsed command.
