Trying to make my editor talk with raddbg, specifically to add watch expressions, I tackled some problems:

• raddbg --ipc toggle_watch_expr [expression] does nothing
• raddbg --ipc toggle_watch_expr_at_cursor adds a watch expression with the first ~1000 characters of the focused file instead of what's under the cursor (probably there's a cap, I suspect it tries to add the entire file)
• raddbg --ipc toggle_watch_pin [expression] does toggle a watch pin at the cursor's location with the correct expression, however -
• raddbg --ipc toggle_watch_pin [filename:line] [expression] does not work at all, as there is no way to specify a different location as everything is considered as a part of the expression (unlike what's written in the readme)
• raddbg --ipc find_code_location [filename:line:column] works, but ignores the column

I'll add that the documentation for those commands currently is not very good, I think adding at least the input fields for each command so it's clear what is the correct way to call them would be already a big improvement.
