Chat Example miss-leading

[arcliox]

example_chat.cpp line 30: crow::mustache::set_base(".");

This line sets the base directory where mustache looks for the template, however this example is miss-leading, unless a custom templates base is set via a blueprint the handle() function of the DynamicRule class sets the directory back to "templates". Moreover if a blueprint is set this would overwrite what the above line does in any case.

Example works if build as part of the Crow build as the CMakeLists file copies the relevant template for this example into ./templates/.

Suggested fix remove line 30.
