[FAQ] How to config STL pretty-printing for lldb-vscode

[zijianyue]

My config:

(setq dape-configs
    '((lldb-vscode modes (c-mode c-ts-mode c++-mode c++-ts-mode rust-mode rust-ts-mode)
                   command "lldb-vscode"
                   compile "make -j10"
                   :type "lldb-vscode" ensure dape-ensure-command
                   :cwd "xxx/build-dbg/xxx/src/"
                   :program "/usr/bin/python3"
                   :args ["EdgeCondTests.py"]
                   :MIMode "lldb" 
                   :setupCommands [
                                   (
                                    :description "Enable pretty-printing for gdb"
                                    :text "-enable-pretty-printing"
                                    :ignoreFailures t
                                    )
                                   ]
                   )))

dape debug output:

[io] Sending: (:arguments (:type "lldb-vscode" :cwd "/home/gezijian/Yuwei/Libra/LibraPackAutoVersion/build-dbg/LibraTask/src/" :program "/usr/bin/python3" :args ["EdgeCondTests.py"] :MIMode "lldb" :setupCommands [(:description "Enable pretty-printing for gdb" :text "-enable-pretty-printing" :ignoreFailures t)]) :type "request" :command "launch" :seq 2) [io] Received: (:command "launch" :request_seq 2 :seq 0 :success t :type "response")

But the std::vector is not displayed as expected, then please tell me how to config it.

I am sorry for taking such a long time to respond.

I don't believe that setupCommands is an valid option for codelldb but maybe :preRunCommands https://github.com/search?q=repo%3Avadimcn%2Fcodelldb+setupCommands&type=issues

But after some quick googling "-enable-pretty-printing" is an gdb command and lldb-vscode does not use gdb.

Maybe you will have some luck with cpptools. I will find a base configuration for cpptools in the latest release on master

[zijianyue]

Yes, cpptools with gdb can work when setting "-enable-pretty-printing", but gdb is slower than lldb in my environment, so I'm trying to use lldb instead.

[svaante]

Then you have to figure out if there is any lldb command that does what "--enable-pretty-printing" does for gdb and consult the codelldb manual.
