Texstudio + custom cwl: #include command ignored

Question

Goal I am trying to derive my own class from memoir and would like to include all the auto-completiong from the original memoir class.

Problem I wrote a customg .cwl file using #include:class-memoir. But that seems to be ignored as the corresponding commands are not recognized in TexStudio. Is there something wrong with the .cwl?

Setting I am using TexStudio 2.11.2 on an Ubuntu 16.04 with pdflatex. I've put the .cwl file in $HOME/.config/texstudio/completion/user and loaded it in TexStudio explicitly in Options->Configure Texstudio->Completion. I am sure that my .cwl is loaded because I added a test command which is recognized.

class-derived-from-memoir.cwl

#include:class-memoir.cwl

\testcmd{asubd}

After loading class-derived-from-memoir.cwl, the part \testcmd{And the test works!} is recognized, but not the memoir commands, i.e. \droptitle, titlingpage, \aliaspagestyle and \cleartorecto.

Answer 1

Maybe your class-derived-from-memoir.cwl file should be

#include:memoir

\testcmd{asubd}
