Adding InitRuntimeFiles() to buffer_test.go has changed the behavior
of this test: now it tests not just buffer editing per se, but also
how well buffer editing works together with syntax highlighting (since
InitRuntimeFiles() loads syntax files, and many of the test buffers
match the json header pattern in the json.yaml syntax file, so they are
"highlighted" as json). This revealed long existing races between
buffer editing and syntax highlighting.
Until we fix those races, temporarily disable InitRuntimeFiles() in this
test.
When initializing runtime files (syntax files etc) in tests, initialize
built-in runtime files only, to ensure that the tests are not affected
by whatever is in ~/.config/micro/ on the test machine.
micro_test.go already ensures that, by using its own temporary directory
as an (empty) config directory. So we only need to fix buffer_test.go
and rtfiles_test.go. In those tests, don't repeat the same dance with
a temporary directory, instead just ignore the config directory.
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.
