- When a surrogate pair is about to be split down the middle we reduce the size of our split by 1 character. This way we split right before a surrogate pair. In the case of zero width joiners, if we split on a zero width joiner we still render valid bytes because the zero width joiner by itself can stand alone.
- Added tests for the various split cases.
#2470
- Added the necessary infrastructure to serialize and verify the syntax
tree
- Updated ParserVisitor to be overrideable
- Made CSharpVerbatimBlockTest to use baselines
- Prior to this change we weren't strict enough with where our smart indenter ran. We made the assumption that every code block could be smart indented and then Roslyn would "do the right thing". However, in nested code block scenarios we found that Roslyn and us would both indent resulting in extra newlines. These changes make the criteria for applying smart indentation a little stricter.
- Updated directive code block parsing to add a C# marker symbol in cases of an empty code block directive.
- Added unit tests to verify new smart indenter behavior.
- Updated existing tests to expect new syntax tree marker symbol for empty directive bits.
- Regenerated baselines.
#2410
- Added ability to understand valid inserts, deletes and replacements for the `@functions` directive (and any other directive that uses our extensible code block bits).
- Added unit tests.
- Updated existing tests.
- Found an issue when completing some C# items the auto-completions would impact the underlying snapshot after we'd captured the change. Fixed this by forcing a reparse when we detect that our understanding of the latest snapshot and the actual latest snapshot diverge.
#2408
A common cause for runtime view compilation failure in MVC is when an application is published
without reference assemblies. MVC usually handles this at compilation, by looking for specific
error codes. More recently, TagHelper discovery fails with an not-so-helpful error message in this
scenario. This change attempts to add a little more error checking to cover the most common cases
- Allow identical `@using` directives in the primary document. This means that if a user types `@using System` twice in the primary document (i.e. `Index.cshtml`) then we'll generate that using statement twice; this enables proper C# IntelliSense to light up on both using statements and allows auto-completion to work because there's no more magical distinction logic for Razor code that is in the current document.
- Prior to this change if you had two identical using statements in the same document one would be in no-mans land mapped to nothing (not C#, not HTML) and the other would be mapped to C#; the second a user differentiated the two statements (i.e. adding a `.`) we'd distinctify the using statements resulting in an invalid completion.
- This PR has an end-user impact where they will now receive the normal C# warning about having duplicate using. I treated this prior behavior more as a bug because we threw away the first using directive instance which impacted editing and in general was a silly thing to correct for the user.
- Added new integration test showing how using directives are not de-duplicated in the primary document.
#1255
- This is part of a fix for #1255 - this change enables signature help in implicit expressions by improving the partial parsing. We're now smart enough about the contents of an implicit expression and attempt to balance parenthesis to determine if we should not full parse.
#1255
- We need to pre-emptively generate line pragmas to handle C# scenarios which are session based. For instance, if a C# completion session starts at a location without a pragma they capture the origination point; at which point if a user keeps typing we generate a line pragma drastically changing where the copmletion started resulting in a broken C# completion experience.
- Updated test files to reflect new behavior.
#2299
- Prior to this change our brace smart indenter would indent JavaScript blocks incorrectly because it didn't take into account where in a Razor file the brace that it was indenting existed.
- Made it so the brace smart indenter only functions in code/metacode locations within the SyntaxTree.
- Updated and added tests to account for new behavior.
#2297
- VisualStudio defaults to adding a `<none>` link item when right click -> add existing item for Razor files; therefore, this also includes the knowledge of the "None" item group when finding Razor files.
- Added unit and functional tests to verify the new `FallbackRazorProjectHost` behavior.
- Added new schema items to represent the `Content` and `None` item type information (pulled from the project system repo).
#2373
We want to have a way to specify the taghelper descriptors and imports to use while
processing a specific document.
- Added an overload to Process and ProcessDesignTime to take in a list
TagHelperDescriptors and a list of imports
- Added the corresponding CreateCodeDocumentCore overload
- Added GetTagHelpers and SetTagHelpers extension methods for
CodeDocument
- Added the necessary plumbing to use the taghelpers from the
CodeDocument when available and fallback logic.
- Added DocumentImportsTracker and updated background code generation
logic to use the new overload
- Added/updated tests
- First iteration of live share replaced the document tracker factory entirely; however, this will be prone to breaking changes in the future when me make changes to document tracker to not rely on a file path. To pre-emptively prevent breaking changes I added a project path provider that can be overridden in the live share case. Note that one big difference here between old and new is that instead of being a MEF service implementation for the project path resolution we're bringing that to the Workspace service level.
- Added tests to validate the two flows of the default project path provider.
- Prior to this the parser would think that a non-latest reparse request was the latest because the only way we would check to see if a change reference was "latest" would be to do an equality check on the snapshot and `SourceChange`; the issue here was that `SourceChange` was null but the snapshots were the same. Problems could arise with this due to project context changes.
- Added tests to validate the new reparse behavior.
- Renamed `Edit` in the `BackgroundParser` to `ChangeReference` also refactored all the "edit" text in `BackgroundParser` to be `ChangerReference` like.
- Added a new event args to be the DTO between the internal and external parser implementations. This is how we could pas additional information in order to determine "latest" change reference.
#2336
This change intoduces content changes to our project snapshots. We now
know the open/closed state of documents that are initialized by the
Razor project system and listen to the correct data source based on
whether the file is open in the editor.
There are a few other random improvements in here as well like a
workaround for the upcoming name change to our OOP client type.
- MEF is the primary means of resolving the new live share provider therefore we allow it to not be registered.
- The new contract is in the Editor.Razor binary so the LiveShare bits don't have to take the dependency on the windows binary in Razor (has a lot of baggage).
- This is specific to live share but providing a generic way to resolve workspaces didn't seem reasonable given the varying expectations in VS4Mac. If we need to make a more generic solution in the future we'll revisit this; for now this is a straight forward inclusion of live share functionality.
- Added tests to validate the new behavior.
- This unblocks the live share scenario of resolving the remote workspace. We can't rely on the projection buffers to provide the correct workspace because that workspace is wired up too late in the process of opening a Razor file.
#2335
FastUpToDateCheck in VS doesn't account for changes solely to .Views.dll. This causes referencing projects to be treated as
up to date even though a referenced project rebuilt. Touch the marker file to cause referenced projects to rebuild.
Fixes https://github.com/aspnet/Razor/issues/2306
to cause it to treat
The project snapshot now maintains a RazorProjectEngine as well as set
of Tag Helpers that are known for that snapshot.
Pivoted some more services to be snapshot-centric.
Also added the ability to track .cshtml documents to the project system.
For now most components just ignore document changes.
Recent builds of msbuild have node reuse enabled by default. This locks up the
task dlls after the test's completed preventing rebuilds untill you kill the process.
This change will allow someone extending Razor to use generic type
parameters in generated classes.
There's no user-level extensibility provided here yet, as in there is no
language support for adding type parameters.
