Adding InitPlugins() to tests has caused noisy error logs when running
the buffer_test.go test (although the test result is still PASS):
2024/03/23 15:14:30 Plugin does not exist: autoclose at autoclose : &{autoclose autoclose <nil> [runtime/plugins/autoclose/autoclose.lua] false true}
2024/03/23 15:14:30 Plugin does not exist: comment at comment : &{comment comment <nil> [runtime/plugins/comment/comment.lua] false true}
2024/03/23 15:14:30 Plugin does not exist: diff at diff : &{diff diff <nil> [runtime/plugins/diff/diff.lua] false true}
2024/03/23 15:14:30 Plugin does not exist: ftoptions at ftoptions : &{ftoptions ftoptions <nil> [runtime/plugins/ftoptions/ftoptions.lua] false true}
...
These errors are caused simply by the fact that plugins are initialized
but not loaded. Adding config.LoadAllPlugins() to buffer_test.go "fixes"
this problem.
However, at the moment it doesn't seem a good idea to load plugins in
buffer_test.go, since buffer_test.go doesn't properly initialize Lua. It
only does ulua.L = lua.NewState() but doesn't do the other stuff that
init() in cmd/micro/initlua.go does. As a result, plugins will not be
able to do anything correctly.
So in order to initialize Lua correctly we need to be inside cmd/micro/,
so we cannot do it in buffer_test.go or any other tests except
micro_test.go.
* rtfiles: Initialize all-/realFiles and Plugins in InitRuntimeFiles
* command: Reload plugins at ReloadCmd too
* command: Don't reload plugins in case of ReloadConfig()
* rtfiles: Split InitRuntimeFiles() into one func for assets and one for plugins
* rtfiles: Remove the unnecessary init function
With this modification the InitRuntimeFiles() and InitPlugins() (if needed)
must be called first, otherwise uninitialized runtime file variables are most
likely.
