func (*Server) Diagnose 

func (s *Server) Diagnose(uris ...protocol.DocumentURI)

Diagnose runs various checks over a ttcn3 test suite.

From LSP spec: 

Diagnostics are "owned" by the server so it is the server's
responsibility to clear them if necessary.

If a language has a project system (for example C#) diagnostics are not
cleared when a file closes.  When a project is opened all diagnostics
for all files are recomputed (or read from a cache).

When a file changes it is the server’s responsibility to re-compute
diagnostics and push them to the client. If the computed set is empty it
has to push the empty array to clear former diagnostics. Newly pushed
diagnostics always replace previously pushed diagnostics. There is no
merging that happens on the client side.

type Suites added in v0.7.0 

type Suites struct {
	// contains filtered or unexported fields
}

Suites implements the mapping between ttcn3 source files and multiple test suites.

The language server must be able to correctly handle multiple test suites in parallel. For example, if a user edits a file, which is imports from two independent test suites the language server must not throw a redeclaration-error.

How do we solve this problem? Virtually all lsp features initiated from a open file. For every didOpen-event we check if the opened file is owned by at least one test suite. If there's not, we load a new suite by using the file's directory and various other inputs as heuristic.

func (*Suites) AddSuite added in v0.9.1 

func (s *Suites) AddSuite(root string)

AddSuite add a TTCN-3 test suite to the list of known suites. the list of know suites.

func (*Suites) FirstSuite added in v0.9.2 

func (s *Suites) FirstSuite(uri string) (*ntt.Suite, error)

FirstSuite returns the first test suite owning the file or an error if not owning suite was found.

func (*Suites) Owners added in v0.7.0 

func (s *Suites) Owners(uri protocol.DocumentURI) []*ntt.Suite

Owners returns all Suites that require the opened file.
