zig-gdb

Commands and pretty printers for debugging the Zig compiler (stage 1).

Installing

Clone this repository somewhere that's on GDB's Python path; name it zig. For example, if ~/.config/gdb/python is on your path, do

git clone https://github.com/matthew-mcallister/zig-gdb.git ~/.config/gdb/python/zig

If you haven't configured your path yet, try adding this to your .gdbinit:

python
import os
import sys
sys.path.append(os.expanduser('~/.config/gdb/python'))
end

Next, configure GDB to automatically load the package and install its printers. If you haven't already, configure your auto-load path:

add-auto-load-safe-path "/home/<username>/.config/gdb/auto-load"
add-auto-load-scripts-directory "/home/<username>/.config/gdb/auto-load"
# Uncomment if you have trouble getting auto-load working
#set debug auto-load on

Finally, create the following auto-load script:

import zig
zig.register_printers()

The script must be named zig-gdb.py and placed in a precise location, namely <auto-load dir>/<zig binary dir>/zig-gdb.py. E.g., if the zig executable were at /usr/bin/zig and you followed the previous examples, name it ~/.config/gdb/auto-load/usr/bin/zig-gdb.py.
