use simultaneously gef and the original gdb display

Hi,

Type of feature request

Misc

new gdb display in the gef layout

Summary Description

this is my usual layout config

gef config context.layout "legend regs -stack code -args -source -threads -trace extra memory"
gef config context.nb_lines_code 25

I use sometimes

memory watch &my_address 100 byte

but I miss the original gdb display

display my_structure

could we have something like

gef config context.layout "legend regs -stack code -args -source -threads -trace extra memory gdb_display"

or is it already doable to get both gef layout and gdb display simultaneously ?

Implementation idea/suggestion

empty

Existing alternatives?

This is already feasible using custom panes

[Rehan-MALAK]

interesting ! thanks !

for now, I am not sure how to do this correctly though

gdb_display = "gdb_display"

def gdb_display_callback():
    output = gdb.execute("display", to_string=True).strip()
    gef_print(output)

def gdb_display_callback_title():
    return gdb_display

register_external_context_pane(gdb_display, gdb_display_callback, gdb_display_callback_title)

doesn't display the nice colors of the gdb display command

and using directly gdb.execute

# gef config context.layout "legend regs -stack code -args -source -threads -trace extra memory gdb_display"
gdb_display = "gdb_display"

def gdb_display_callback():
    gdb.execute("display", to_string=False)

def gdb_display_callback_title():
    return gdb_display

register_external_context_pane(gdb_display, gdb_display_callback, gdb_display_callback_title)

is not rendering the output of display in the correct panel (but at the beginning of the screen)

this panel should exist only if display is actually returning something (as the memory watch is behaving)

actually , sudo apt update && sudo apt install --upgrade gdb-multiarch gdb updated on my machine gdb from 16.3-5 to 17.1-2 with the styling=True parameter to gdb.execute

https://gnu.googlesource.com/binutils-gdb/+/e5348a7ab3f11f4c096ee4ebcdb9eb2663337357

which solves the 1. with

gdb_display = "gdb_display"

def gdb_display_callback():
    output = gdb.execute("display", to_string=True, styling=True).strip()
    gef_print(output)

def gdb_display_callback_title():
    return gdb_display

register_external_context_pane(gdb_display, gdb_display_callback, gdb_display_callback_title)

need to figure out the 2. now
