How do I start emacs with a command and its option, for example, I want emacs start with entering gdb mi mode, otherwise it does not go to the gdb mode during startup.

The following works:

emacs gdb

Or using evaluate:

emacs gdb -e gdb

But I want to enter the mi mode and this does not work:

emacs gdb -i=mi

Or this:

emacs -e gdb -i=mi

Unfortunately I just want to enter mi mode directly during startup.

  • Use a .emacs file or init.el file and customize it, or learn how to pass arguments from the command line that include elisp. If you do a bit of Googling, you will find a zillion hits. E.g., Evaluate emacs lisp expession on command line stackoverflow.com/questions/11474774/…

    The following link has an example that you can work with and modify as needed: stackoverflow.com/questions/35577536/gdb-in-emacs-24-messed-up You should be using Emacs 25 at this point unless there is a good reason for using an earlier version.

The following works:

emacs --eval "(gdb \"gdb -i=mi\")"

    Using simple quotes removes the need for backslash escapes. Also, you can include executable name in that command emacs --eval '(gdb "gdb -i=mi ./myexecutable")' & . You might be interested also in -x option of gdb that starts a specific script. Or include source localgdbscript in your ~/.gdbinit so that a localgdbscript in your local directory is automatically run. Mar 10, 2017 at 10:22
