<div dir="ltr"><div>I'm in a room with several folks that work on Linux and Mac. One of the major complaints with lldb is the command syntax when switching between the two debuggers. Currently, everyone prefers the gdb syntax. I'm sure a large part of that is due to knowing gdb after using it for so long, but also because some of the commands are much simpler. "ptype Point" vs. "image lookup --type Point", "info symbol 0x1234" vs. "image lookup --address 0x1234", etc. I'm sure there are other folks dealing with this issue when they move to lldb from gdb, and there appear to be several gdb --> lldb aliases already built into lldb - I assume to help with this. So instead of having several different people each trying to solve this for themselves with local python scripts or init files and all the issues that come along with those, I was thinking it would useful to get some more gdb commands it into lldb. Ie, ones like "info" that are fairly simple and don't interfere with existing lldb commands. But we'll take a look at the .lldbinit file Jason mailed, python scripts, and if those don't work for us I'll investigate Enrico's multiword commands idea and possible local lldb modifications.<br>

I recommend this way also. Actually, we have already done this thing<br>
for our GUI for lldb. It is not hard at all.<br>

Just write a new python command and name it "info". Then re-route as needed under the covers.<br>

Would it make the most sense to add a new "CommandObjectMultiwordInfo" object in the Command Interpreter and break all the info stuff out there, or is it feasible to add the ability to recognize multiword aliases so something like this would work:<br>
