analyzeDiagnostics

public · function · Source (opens in a new tab)

llvm::json::Array sun::lsp::analyzeDiagnostics(const OpenDocument &document)

Analyzes the current document text and collects compiler diagnostics.

Related: OpenDocument

appendDiagnostic

public · function · Source (opens in a new tab)

void sun::lsp::appendDiagnostic(llvm::json::Array &diagnostics, const OpenDocument &document, const std::string &message, const std::optional< sun::support::Position > &location, int severity, const std::string &knownSourceLine="")

Add one diagnostic for a message and the place it points at.

A location in this document is marked where it happened; one in another file (a manifest sibling, or a library body instantiated from a bundle) is shown at the top of this document, naming where it came from.

computeSemanticTokens

public · function · Source (opens in a new tab)

std::vector< int > sun::lsp::computeSemanticTokens(const std::string &source)

Compute semantic tokens for a document Returns encoded token data as per LSP spec: [deltaLine, deltaStartChar, length, tokenType, tokenModifiers]...

getAnalyzedDocument

public · function · Source (opens in a new tab)

const AnalyzedDocument * sun::lsp::getAnalyzedDocument(const OpenDocument &document)

Analyzed tree for the document's current text, or null when it cannot be parsed.

Analysis errors keep the partial tree: everything typed before the error still answers hover requests.

main

public · function · Source (opens in a new tab)

int main()

Reads editor requests and runs the Sun language server message loop.

std::string sun::lsp::trimCR(std::string line)

Removes the carriage return from a protocol header line.

uriToPath

public · function · Source (opens in a new tab)
