Martin Atkins	cdf5f0e6ef	lang/langserver: Initial "Go to Definition" implementation ... For the moment this can only seek within a single file, since we don't have the infrastructure in place to load a whole module to search it. It also only knows how to find the definition from... the definition itself. Will elaborate on this further in later commits.	6 years ago
Martin Atkins	5c8fccc8c4	lang/langserver: Produce small TextEdits for Formatting ... Previously as a proof-of-concept we were just replacing the entire file here, but now we'll do more surgical edits of individual lines in the buffer because that gives the client tool an easier time if it's trying to retain existing line-oriented annotations in a source file, such as if a line begins a collapsed region.	6 years ago
Martin Atkins	d2d1b52f43	lang/langserver: Helpers for converting source positions ... LSP and HCL use different representations of source positions, so we need to be able to convert back and forth while translating incoming requests to the HCL API and HCL API responses into LSP responses. Such conversions cannot be exact in the LSP->HCL direction because HCL column positions are at a lower granularity (grapheme clusters) than LSP column positions (UTF-16 code units), and even at the individual codepoint level UTF-16 code units and codepoints cannot be converted one-to-one in the presence of UTF-16 surrogate pairs. Therefore these conversions are for "cosmetic" purposes and should not be used for incoming text editing requests or else our local buffer may get out of sync with the one in the client.	6 years ago
Martin Atkins	e4664a1abe	lang/langserver: Simple implementation of Formatting ... Mainly just to have a proof-of-concept of this doing something, this is a simple implementation of the Formatting method that just replaces the whole buffer with the hclwrite result. In future we should make this instead return surgical TextEdits, but we'll need more infrastructure in place here before that is possible.	6 years ago
Martin Atkins	fe819762b8	lang/langserver: Syncing of file contents ... For now we just sync the entire file on every change, which is not very efficient but is a good starting point to flesh out some other features before we implement incremental sync.	6 years ago
Martin Atkins	cec22e1321	lang/langserver: Stub out DocumentLink ... We have no constructs right now that generate links to anywhere, so we'll just ignore this altogether for now.	6 years ago
Martin Atkins	1d722544fc	lang/langserver: Language server initialization and shutdown	6 years ago
Martin Atkins	81b96766a4	lang/langserver: A do-nothing stubbed out language server ... There's enough here for it to start up and return errors from all calls. The vscode-languageclient Node module is able to make an Initialize call and return the "not yet implemented" error.	6 years ago
