GDB/MI Input Syntax (Debugging with GDB)

command →: cli-command | mi-command
cli-command →: [ token ] cli-command nl, where cli-command is any existing GDB CLI command.
mi-command →: [ token ] "-" operation ( " " option )* [ " --" ] ( " " parameter )* nl
token →: "any sequence of digits"
option →: "-" parameter [ " " parameter ]
parameter →: non-blank-sequence | c-string
operation →: any of the operations described in this chapter
non-blank-sequence →: anything, provided it doesn’t contain special characters such as "-", nl, """ and of course " "
c-string →: """ seven-bit-iso-c-string-content """
nl →: CR | CR-LF

Notes:

The CLI commands are still handled by the MI interpreter; their output is described below.
The token, when present, is passed back when the command finishes.
Some MI commands accept optional arguments as part of the parameter list. Each option is identified by a leading ‘-’ (dash) and may be followed by an optional argument parameter. Options occur first in the parameter list and can be delimited from normal parameters using ‘--’ (this is useful when some parameters begin with a dash).
