- Instead of rendering a null assigning statement for a type token we now render a `default(TTypeToken)`. With this approach type tokens can be value types without creating a design time error.
- Re-generated baseline files to reflect new directive token code generation.
#1176
- Split line mapping validation into its own method.
- Prior to this we were calling the wrong method in our design time code generation integration tests within the Razor.Extensions test project.
- Re-generated line mapping baselines to conform with the cshtml files for Razor.extensions code generation integration tests.
#1351
This change adds an API for Tag Helper discovery.
I also got rid of the 'design time' flag for the provider as an
experimental change. We need to think through the consequences of this
before committing to it. Right now I've left those tests failing until we
can make a decision.
This change decouples VCTH discovery a bit more, but we're still not ready
to move that into a the MVC extensions assembly. For that we need the
ability to discover the MVC extensibility.
- This makes it so if you have catch all `TagHelperDescriptor`s their completions don't apply to every existing completion. Instead, they now only apply to already TagHelperified completions and existing completions that are prefixed with a non-empty TagHelperPrefix.
- Updated existing test to have new expectations.
- Added new test to validate non-empty tag helper prefix case.
#1230
This change removes the default usings for 'System' and
'System.Threading.Tasks' and adds them to the MVC template engine.
This is preparation for removing this feature from the razor options, I
wanted to get all of the intentional diff out of the way.
This is a MEF service that can actively or passively track open ITextViews
and give us information about the Razor initialization state and eventing
when it changes.
The purpose of this is to act as a bridge between the VS mef world and the
roslyn world.
For now this doesn't do any passive tracking of Razor documents, it's only
on demand. That means it will only be initialized and used right now when
you are using the Razor developer tools. This is just to reduce our risk,
it's not ideal to ship code in VS that's doing something without anyone
looking at the result.
- Moved the type out of the Legacy namespace.
- Renamed the types method to `GetBinding` since `TagHelper` is now inferred.
- Updated test names to reflect new method/class name.
- Updated product code variables to reflect new naming (provider => binder).
#1289
- Added a `GetAttributeCompletions` API that's consistent with current Razor's editor expectations.
- Added unit tests to validate all code paths of the new `GetAttributeCompletions` method.
#1120
- These tests validate that our extensible directives do not have code that explodes when an incomplete directive is encountered. This is typically the case when a user is in the midst of typing a directive at design time.
- Added an extensions test and a language test.
#1271
- This involved not using the `First()` method when reading the directives tokens.
- Added two tests to validate an empty directive token and a missed directive token for the `@namespace` directive.
#1268
- Found that our extensible directive string parsing system wasn't consistent with the rest of the extensible directive tokens. Basically, if there were malformed string tokens we'd consume them and pass them along to extensible directive passes. This was a big no-no because it means extensible directive passes weren't able to rely on tokens being passed to them being well-formed.
- Fixed up existing extensible directive tests that relied on output of string tokens.
#1247
- Added C# 7 test to validate questionable features work end-to-end.
- Had to add several explicit package references to let our VS specific packages work as expected.
#1046
- Made a targeted fix to PageDirective that stops it from crashing Visual Studio when its malformed.
- Added unit test to validate PageDirective didn't throw when attempting to determine if something was a page.
- Added an integration test to validate malformed page tags can make their way through the entire Razor pipeline and don't destroy the rest of the content.
#1247
- Prior to this change we'd try to substring a TagHelper directive with length 1 but our substring call would be for -1 (explosions).
- Added tests to validate that `@tagHelperPrefix`, `@removeTagHelper` and `@addTagHelper` all behave properly when they have malformed quotes.
#1242
- Prior to this TModel would be set to a potentially non-fully qualified name. This would cause errors in default MVC templates.
- Regenerated test files to reflect new TModel.
- Updated unit test to reflect new behavior.
#1222
- Prior to this if you had a `TagHelper` whos output hint was not in the final form of the completions we'd fall through into a schema check which resulted in a completion being added when it shouldn't. Example: `TagHelper` for `my-tr` that has an output hint of `tr` would end up getting added to the completion list under `body` because `my-tr` was not in the schema and would then be treated like the `environment` `TagHelper` (a new element).
- Added a test to validate that `TagHelper`s with output hints are cross referenced vs. existing completions and do not fall through to a schema check.
#1225
- We don't want tooling applying tag helper prefix to what we deem `TagHelper`s. Ultimately we should consume all the necessary data and do that work.
- Added two tests to validate that we're applying tag helper prefix to `TagHelper` element completions for catch-all's and non-catch-alls.
#1224
- Prior to this catch-alls were explicitly ignored not to populate the IntelliSense with an excess amount of `TagHelper`s. To maintain backwards compatible expectations this commit reverts that expectation.
- Scoped an existing test to only test its primary scenario.
- Added a new test to verify that catch-alls accurately apply to all completions (including dynamically added ones).
#1219
The problem is that @inject uses the type name, and @namespace can change
it. Setting an explicit order makes sure that these things happen in a
sensible sequence.
- Prior to this removing the `__RemoveThisBitTo__` wasn't sufficient to generate baselines; reason being the constants were defined in the wrong assembly. Since we moved test infrastructure bits around the constants needed to follow.
- Added a new `TagHelperCompletionService` which can be queried for information on what completion information should be provided.
- Added tests to validate the completion service's expectations.
- Fixed an issue where `TagHelper`s with output hints that did not exist in a passed in completion would never be highlighted as `TagHelper`'s; even when their primary targeting element was already in the element completion list.
#1181
This change adds support for @namespace, and introduces a set of
changes that are needed to support @namespace in the parser.
@namespace and @class have always been treated as reserved words by Razor,
with the intent that someday they would be allowed as directives.
This changes makes that possible.
You will still get an error about @namespace being a reserved word if you
don't have the directive.
- A `null` parent tag in all of our other API represents "any" parent tag, or in this case "root". Prior to this change we'd expect the caller to do their own verification of the parent and then assume all `TagHelperDescriptor`s are valid; this isn't sufficient because only our code base should have that knowledge.
#1188
- Prior to this change the `TagHelper` parsing would strip the opt-out character (`!`) from tag names that got passed to the TagHelper matching services. At design time this proved to be a problem because they have their own understanding of the HTML document and only pass us full tag names (names that include `!`). This changes the matching conventions to immediately return false if a tag name is seen to contain the `TagHelper` opt-out.
- Added two `DefaultTagHelperFactService` tests to verify that tag names with opt-out prefixes are denied `TagHelperDescriptor`s.
#1186
This change adds support for accepting a namespace name in extensible
directives. This will be needed for the @namespace directive.
Implemented new parsing and codegen for namespaces using nameof().
Also fixed any issue where we were not global::-qualifying object where it
was used in the design time code for tokens.
- Prior to this change default imports would get line pragmas generated for them because thye'd have a source location but no file path (they were a dynamic document).
- Re-generated C# files to reflect new line pragma changes.
#1110
- The lazy addition of namespaces gives the main document lowering phase an opportunity to add source location information which we then add after the main lowering.
- Re-generated csharp to capture addition of using statements that were previously overridden by defaults/imports.
#1174
- We were generating line pragmas for using directives but not line mappings. This resulted in 0 IntelliSense when written within the Razor editor.
- Regenerated test files to reflect new line mappings.
#1162
- At design time we weren't generating line mappings when a user would type `@` or `@(`. This results in no C# IntelliSense being provided to the user because the editor hasn't mapped any of Razor to the C# buffer.
- Modified the `DefaultIRLoweringPhase` to allow for marker symbols, these symbols .
- Re-generated test files to account for 0 length line mappings on empty expression nodes.
#1155
- At design time we weren't generating line mappings when a user would type `@` or `@(`. This results in no C# IntelliSense being provided to the user because the editor hasn't mapped any of Razor to the C# buffer.
- Updated the design time renderer and design time writer to account for empty expressions.
- Modified the `DefaultIRLoweringPhase` to set source locations on empty expression nodes.
- Re-generated test files to account for 0 length line mappings on empty expression nodes.
#1155
- Prior to this if all instances of `TagHelper`s in an assembly had editor browsable never we'd log an error saying that no TagHelpers were found for that assembly. Until we can evaluate a better fix for this issue I've removed the logic that logs those errors and its corresponding tests/resources.
#1145
- Add API to enable the editor to query information on the state of `TagHelper`s within a Razor document.
- Refactored methods from `TagHelperDescriptorProvider` to be in a `TagHelperDescriptorConventions` class so the language service could use them.
- Added `DefaultTagHelperFactService` tests.
#1120
The RazorParserOptions were only configurable via an internal interface
and an extension method on the builder. This isn't suitable for VS because
we need to be able to update the configuration while the editor is open,
without creating a new engine.
- When `RequiredAttributeDescriptor`s are displayed in an editor their display name differs based on their name comparison mode. If their name comparison mode happens to be a prefix match then we need to append three dots to indicate that it's a required prefix for an attribute.
- Added a new descriptor builder test to validate `DisplayName` is created correctly.
#1119
- Normalize paths to be absolute and to also use forward slashes.
- Updated our `EnsureValidPath` method to be `NormalizeAndEnsureValidPath`.
- Added tests to validate new `NormalizeAndEnsureValidPath`.
- Updated existing tests to react to `NormalizeAndEnsureValidPath` correctly.
#1106
- Removed all design time descriptors and put their API surface into their corresponding descriptor. Part of removing the design time API surface was removing the tracking of `<Remarks>`, it wasn't used so there's on need to track it until we need it.
- Removed the Type requirement from `TagHelperDescriptor`. With this separation we'll be able to have abstract `TagHelper`s that aren't based on a class implementation.
- Removed Prefix from the `TagHelperDescriptor` API surface. It was a legacy requirement based on how the Razor parser was put together. We can work around this now.
- Stripped correlation information from the immediate `TagHelperDescriptor` API surface. Instead this information is now tracked in `TagMatchingRule`s. This change means that you will not have multiple `TagHelperDescriptor`s per `TagHelper`; instead it's all tracked in a single descriptor. A side effect of this change was the transformation of `IsIndexer` => 3 new properties.
- Renamed many descriptor types and property names.
- Added builder APIs to construct TagHelpers since they're inherently immutable in their API surface.
- Added `ITagHelperDescriptorBuilder` to represent `TagHelper`s that are built from an `ITagHelper` implementing class. It re-introduces the `TypeName` association of a `TagHelper`.
- Added `ITagHelperBoundAttributeDescriptorBuilder` to represent that an attribute was associated with a property.
- Added validation methods to the descriptor builders to enable consumers to validate the current state of the builder and add diagnostics as necessary.
- Moved descriptors away from RazorError.
- Updated the various comparers to understand the descriptors new API.
- Added a new `RazorDiagnosticFactory` abstraction to handle `RazorDiagnostic`s and their corresponding errors/ids etc. This new API should allow for easy addition of new `RazorDiagnostic` errors.
- Updated the `DefaultTagHelperDescriptorFactory` to construct `TagHelperDescriptor`s using the new builder APIs and in the new descriptor format (1 descriptor per type).
- Updated `ViewComponentTagHelperDescriptorFactory` to construct `TagHelperDescriptor`s with the builder API.
- With both factory implementations code was duplicated because the ViewComponent work will be moving outside of Razor once we have the proper hooks.
- Updated `TagHelper` binding bits to capture a binding result in order to query which rules appy to a given tag name.
Addressed feedback
- Update tests to react to new `TagHelperDescriptor` API.
- Remove case sensitive comparers and some cleanup
- Added TagHelperDescriptorJsonConverter, RazorDiagnosticJsonConverter and added serialization tests
VS has gone RTM so, updating to the RTM versions of those dependencies.
Roslyn does not publish our shim packages on NuGet.org, so updating those
to a non-ancient version for projects that use 2.0.0. The projects that
use 1.3.x are staying put for now.
The code change is dealing with something that was obsoleted.
This will make is much easier to investigate failures that bubble up to
the codegen level. You'll be able to see if there was a change to the IR
rather than just the final code.
Deletes CSharpIRToken to use the more general RazorIRToken class.
Rather than using the visitor to visit tokens, now writing a
CSharpExpresionIRNode is an 'atom', and will write its tokens itself.
This IR node will be part of the new token model for IR. It will be used
by all nodes that contain user content. Going forward, tokens will be the
thing that contains text and produces line mappings.
This commit just introduces the class.
This change fixes a bug where DefaultRazorIRLoweringPhase is too
aggressive in merging HTML spans. You can hit the bug by delimiting two
html spans with a metacode character like:
<foo>@{ <bar/> }</foo>
The lowering phase will combine these HTML nodes, which is invalid as they
don't have contiguous spans.
The change here is to merge spans only when they both have an invalid
location or are contiguous.
Introducing ExtensionIRNode and an implementation of templates based on
the new feature set.
Now TemplateIRNode is-a ExtensionIRNode. It's implemented using just
extensibility and isn't part of the standard razor codegen. I'm adding it
to the RazorEngine so that it's still there by default.
I've also included a pattern for visitors to special case
ExtensionIRNode-derived classes that they know about. This requires a
little bit of boilerplate but makes it easy to traverse just the nodes you
care about while keeping the set of nodes open.
For now the general codegen feature still hasn't had a refactor, but this
opens things up for us to start finishing things like MVC's @inject
directive.
- Added DirectiveRemovalIRPass
- Added IRazorDocumentClassifierPhase, IRazorDirectiveClassifierPhase and
IRazorIROptimizationPhase
- Added all the related passes and default implementations
- Refactored DefaultDirectiveIRPass to do the right thing
- Execute method in IR passes now return void
- Added tests for the new phases
This is a new abstraction that represents the api surface available for
codegen to target. Every kind of document should have an associated
RuntimeTarget or just use the default.
To prevent breakage, our DocumentClassifierBase class will provide a
default API set to implementors (like MVC).
I haven't fundamentally changed how codegen is done yet, I've just hidden
it behind a new abstraction. The RuntimeTarget now is also responsible for
selecting between design time and runtime.
The bulk of the noise here is from splitting a lot of the codegen stuff
into its own files.
- Literal directive tokens acted as a way for a user to provide markup bits to be required when parsing a directive.
- Removed source implementations.
- Removed tests validating the feature.
#969
- Roslyn swapped the way they performed dotless commit insertions. They went from:
date => date. => DateTime. to
date => date. => date => DateTime => DateTime.
The problem with the new approach is that date => DateTime would be rejected and therefore force the editor to reparse and reclassify any dots as HTML giving improper IntelliSense.
- Updated Razor implicit expression edit handling to allow identifier => identifier replacements as long as the identifiers didn't result in keyword or directives.
- Added tests to verify the scenarios impacted.
This is a replacement for RazorError, is conceptually equivalent with
Diagnostic from Roslyn.
The next PR will start exposing this through our public API rather than
the legacy type.
The issue here is that when a taghelper prefix is in use it will be
including in the HTML output, when it should be chopped off.
See the diff in the codegen for examples.
This change does deduplication of taghelpers during the binding/rewriting
phase. This is needed when a taghelper has multiple sets of html
attributes that are required (behaves like an OR). This is used lots in
MVC.
The old codebase used to do this in the codegen phase, but it seems
beneficial to do as early as possible.
The IR lowering phase was attaching the 'tag helper fields' node to the
builder instead of to the top-level node (document). This meant that
things wouldn't be where we expect when the first tag helper occurrence is
inside a directive block (section).
Found this porting MVC to use the new Razor codebase.
We're close to hooking up new Razor to MVC. This is a set of enabling
'quick fix' changes to resolve some blockers to using Razor.Evolution in
the product.
Main issues:
- Types not public enough - anything in the .Legacy namespace is still
slated from 'improvement'
- Wrong references. We don't want .Workspaces in MVC, so moving the heavy
lifting of TagHelper discovery to CodeAnalysis.Razor.
This commit adds support to the TagHelperBinderSyntaxTreePass to interpret
@addTagHelper, @removeTagHelper, and @tagHelperPrefix.
I also ported all the original tests for this feature and updated them to
call new APIs.
The bulk of the changes here were updates to baseline tests that weren't
correctly using @addTagHelper
This change adds support for 'imports' - extra source files which contain
directives that can merged with 'main' source files. The purpose of course
is to support things like global usings or addTagHelpers, like
_ViewImports in MVC does today.
Instead of a one-off this is now a feature of the Razor langugage since
things like addTagHelper have an impact on the parsing behavior. Also,
having a standard imports concept keeps out feature creep, for instance
the 'global' usings we have today could really just be an import.
Imports allow single-line directives including the fundamental directives
like addTagHelper, using, and other friends. Code, content, and block
directives are not merged and will be ignored. We can consider making
these kinds of things warnings in the future.
- Hardcoded `ViewComponent` discovery.
- Hardcoded `ViewComponentTagHelperDescriptor` creation.
- Added test to validate that ViewComponents are discovered and transitioned into TagHelpers properly.
- Avoided adding a reference to MVC to prevent circular references. This resulted in custom marker attributes to represent `ViewComponent`s. Also made a lot of use of `ViewComponent` conventions (ending in "ViewComponent").
#932
Also adds the source document to the RazorSyntaxTree and does some cleanup
related to this. This lets us verify which tree goes to which document and
that seems important.
Added basic tests to verify that parsing happens, though it's not being
used for anything right now.
- Ported the existing descriptor factory tests and fixed issues with the current implementation.
- Ported documentation tests with the exception of the localization variants.
- Updated the DefaultTagHelperResolver to filter TagHelper types based on accessibility.
- Added DefaultTagHelperResolver tests.
#851
This change defines stages for IR processing. The comments in RazorIRPass
really explain the details. I've also made the preliminary changes to the
stuff we've built so far to follow the new conventions.
This is building towards multitargeting for Razor, being able to target
both Razor Pages and Razor MVC Views from the same engine, being able to
target different codegen and methods from within the same engine.
This change ensures that spans are contiguous and that all source is part
of a span. This means that a character can't be 'lost' and not a member of
any span.
And guess what? We have a bug like that. So now a few tests are skipped
due to that bug.
Also made some changes to tests that construct invalid spans or spans
without correct locations as their expected input. This allows us to add
the above verification to all parser tests.
- Added a common csharp rendering phase base to put shared assets of runtime and design time code gen.
- Added a new `DesignTimeIRPass` to setup the IR bits to provide accurate intellisense.
- Added a `CodeGenerationIntegrationTest` and moved the RuntimeCodeGenerationTests into it. This way we can re-use the cshtml files and it makes searching/running the tests easy..
- Updated how line mappings are calculated for some nodes.
#848
- Previously we'd special case `@section` at code generation time; now we transform the directive into an IR node.
- Changed the expectations of `DefineSection` to not take in a section writer. It's now expected to modify what `Write`, `WriteLiteral` etc. write to when inside of the lambda. This is done today in TagHelpers via `StartTagHelperWritingScope`.
- Updated baseline files to reflect new `DefineSection` expectations.
- Updated IR tests since we no longer leave around `DirectiveIRNode`s.
#901
- Source ranges currently aren't normalized when they're input into the system. Due to how we serialize pieces of the code this breaks cross plat because of newline differences.
- This is a temporary work around to get the build passing cross plat.
- If needed, a phase/feature can always retrieve the syntax tree to lookup whether the parse tree was made in a "design time" fashion.
- Future DesignTime / Runtime specific bits will be added to their corresponding `AddRuntimeDefaults`/`AddDesignTimeDefaults` methods.
- Added TabSize,IsIndentingWithTabs and NamespaceImports to the RazorParser options. These are replacements for the existing RazorEngineHost abstraction.
- Added RazorParserOptions consumption pattern to more than just the parsing phase.
- Added a ChecksumIRNode to ensure Debugging can work.
- Updated tests to to react to new Checksum and Namespace nodes in the IR tree.
- Removed existing type names used to track `@functions`, `@section` and `@inherits`.
- Updated parsing logic to reflect existing directive behaviors.
- Added additional IR and syntax tree pass in order to fulfill the default directive expectations.
- Updated tests to to expect new extensible directives parse structure.
#894
- Prior to this the platform that the newlines were escaped on would be the platform the baselines would pass on.
- Updated baselines to reflect new newline escaping.
#888
- Also modified the property name from `SourceLocation` => `SourceRange` to avoid ambiguity.
- Updated IR baselines
- Updated IR baseline infrastructure to conditionally render the document location.
#884
This change adds a basic framework for doing baselined integration tests.
This is very similar to what we do elsewhere with generated files and
tests that read them from resources.
What's here now is the support to do this kind of baselining with IR in a
pretty readable serialization format.
This is a building block and the intent is that we'd do something similar
in the future for syntax nodes and C# source.
Looking at the code of the tests in particular, we'll also build the
ability to capture the documents at key points (such as before/after a
targeted phase) and then verify them in the same manner.
This change adds a way to actually configure the RazorEngine to use
extensible directives (previously buried behind legacy API). As part of
this feature adds the RazorParserOptions class to encapsulate anything
else that becomes a parser options (ahem taghelpers).
Now we have a pattern for this when we get there.
Options are propagated as part of the RazorSyntaxTree for
testability/sanity and this was actually responsible for the bulk of the
changes.
Also added some extension methods for adding directives to the
IRazorEngineBuilder and an end to end integration test.
This change adds a phase which runs IR passes. Design and code are almost
exactly the same as the existing SyntaxTree phase. However all of this is
public because the IR is public API.
- Based generic directive implementation off of descriptors.
- Added parsing logic to consume descriptors and parse content that's expected.
- Added parsing errors to automagically detect unexpected directive pieces.
- Updated visitor implementations to understand the directive bits.
- Added a builder abstraction to easily create descriptors. Had to maintain the ability to manually construct a descriptor to enable convenient serialization/deserialization.
- Added tests/comparers to verify correctness of parsing.
#853
- Add an `HtmlNodeOptimizationPass` that does all of the `RazorSyntaxTreeRewriting` that legacy used to achieve outside of `TagHelper`s.
- Add tests for `HtmlNodeOptimizationPass` to verify it's executing appropriate bits.
#849
- Added conditional attribute test.
- Reacted to Html optimization pass in tests.
- Removed directive IR bits since they'll be handled by the extensible directive system.
#844
- Added a TagHelperFeature to hold TagHelper specific pieces that can be replaced.
- Built a syntax tree pass that applies the ported TagHelper bits.
- Updated tests that expected different RazorEngine defaults.
- Added new tests to verify binder pass.
- Modified how tests are run to reflect our new test infrastructure.
- Added TagHelper assertion bits.
- Moved all classes to the Evolution.Legacy namespace.
- Copied Test.Sources bits to the Evolution.Test project.
#845
- Removed the `CreateReader` API in favor of a `CopyTo`, `Length`, `[index]` and `Encoding`.
- Updated existing APIs to react to the change.
- Added tests.
This is an API skeleton for the IR data model that we'll be using as a
spiritual continuation of the 'chunks' API. Currently missing a lot of
detail which will be filled in as needed.
