gdb-call-lambda 0.0.2

Call C++ lambda functions from gdb

gdb-call-lambda

Call C++ lambda functions from gdb.

Install

• Install the Python package in somewhere Python can see.
• In .gdbinit add:

python import gdb_call_lambda

Usage

Call a lambda like printl f(x), where the f is the lambda.

I.e., call as usual, just replace print with printl.

The lambda expression (f in this case) must not have any ( characters.

Alternatively, use the convenience function: print $calll(f, x)

How it works internally/what to do if it doesn't work

See post https://stackoverflow.com/a/70254108/5267751.

There's a known bug where gdb/tools can't demangle a symbol that gcc generates, see B in test.
