Bicep.LangServer 0.46.1 (latest release) does not implement these three LSP
features, so iLSP now answers them itself directly in the proxy instead of
forwarding to the underlying LS:
- textDocument/signatureHelp: curated database of ~50 commonly used Bicep
built-in functions (resourceId, guid, concat, take, format, ...) with a
simple bracket-depth call-context detector (ilsp/bicep_lsp/bicep_functions.py,
ilsp/bicep_lsp/local_features.py:compute_signature_help).
- textDocument/foldingRange: stack-based bracket matcher over {}/[]/() plus
contiguous // comment-block folding (compute_folding_ranges).
- workspace/symbol: best-effort search over documents currently open in the
editor session (iLSP has no full-workspace index, only what's been opened),
matching top-level resource/module/var/param/output/func/type declarations
(compute_workspace_symbols).
The proxy now advertises these in the initialize response capabilities
(signatureHelpProvider, foldingRangeProvider, workspaceSymbolProvider) so
editors actually send the requests, and intercepts them in _client_to_ls
before they'd otherwise be silently dropped/errored by the real Bicep LS.
A send lock (_LockedConn) prevents interleaved frames now that both
_client_to_ls and _ls_to_client can write responses to the client socket.
13 new unit tests in tests/test_local_features.py. Closes the last 3 gaps
found in the full LSP capability audit.
