" Debugger plugin using gdb. " " Author: Bram Moolenaar " Copyright: Vim license applies, see ":help license" " Last Change: 2023 Nov 02 " " WORK IN PROGRESS - The basics works stable, more to come " Note: In general you need at least GDB 7.12 because this provides the " frame= response in MI thread-selected events we need to sync stack to file. " The one included with "old" MingW is too old (7.6.1), you may upgrade it or " use a newer version from http://www.equation.com/servlet/equation.cmd?fa=gdb " " There are two ways to run gdb: " - In a terminal window; used if possible, does not work on MS-Windows " Not used when g:termdebug_use_prompt is set to 1. " - Using a "prompt" buffer; may use a terminal window for the program " " For both the current window is used to view source code and shows the " current statement from gdb. " " USING A TERMINAL WINDOW " " Opens two visible terminal windows: " 1. runs a pty for the debugged program, as with ":term NONE" " 2. runs gdb, passing the pty of the debugged program " A third terminal window is hidden, it is used for communication with gdb. " " USING A PROMPT BUFFER " " Opens a window with a prompt buffer to communicate with gdb. " Gdb is run as a job with callbacks for I/O. " On Unix another terminal window is opened to run the debugged program " On MS-Windows a separate console is opened to run the debugged program " " The communication with gdb uses GDB/MI.
