* Markdown path completions tests use mocked out fs
This updates the path completion tests to stop depending on the actual fs and instead use `IMdWorkspace`
* Update remaining tests
Renames in the markdown extension
This renames some types and splits up some files as part of an exploration towards a proper LSP. Changes:
- `SkinnyTextDocument` -> `ITextDocument`
- Moved `ITextDocument` to own file
- `MdWorkspaceContents` -> `IMdWorkspace`
This change reduces the number of times we retokenize a markdown file by doing the following:
- Use `MdTableOfContentsProvider` in more places
- Introduce a `IMarkdownParser` interface that lets us drop in a caching version of the tokenizer
(sorry for the size of this PR)
This change cleans up the markdown language features by making the following changes:
- Use `registerXSupport` public functions to register these
- Expose the slugifier the `MarkdownEngine` uses. You never want to use a different one if you already have a markdown engine
- Sort of clean up names. I'd introduced a bunch of confusing names while iterating in this space. What I'm working towards:
- `Computer` — Stateless thing that computer data
- `Provider` — Potentially stateful thing that provides data (which may be cached)
- `VsCodeProvider` — The actual implementation of the various vscode language features (which should only be used by VS Code and in tests, not shared with other features)
- Introduce `MdLinkProvider` to avoid recomputing links for a given document. Also use this to hide more internals of link computation
- Use `vscode-languageserver-textdocument` instead of custom impl
- Reuse `InMemoryDocument` across tests and working code
- Use `SkinnyTextDocument` in more places
- Fixes some test errors that seem to be caused by bad `InMemoryDocument` impl
