- relates to #89 because that changes `string` property checks and needs this refactor
- determine `string`-ness when creating `TagHelperAttributeDescriptor`s
- add `TagHelperAttributeDescriptor.IsStringProperty` (set in constructor)
- avoid repeated `string` comparisons and be more explicit
- change `TagHelperBlockRewriter` to centralize more of the `string`-ness determination
- also add `TryParseResult` DTO, avoiding multiple `out` parameters
- refactor `CSharpTagHelperCodeRenderer` to allow reuse of core attribute value rendering
- test all of it
- add `TagHelperDescriptorTest` to confirm serialization / deserialization
minor:
- fix `TagHelperBlockRewriter.TryParseBlock()` end quote removal when tag is malformed
nits:
- remove dangling mention of fixed bug #220
- make recently-added `TagHelperBlockRewriterTest` tests realistic
- multiple `TagHelperDescriptor`s for same tag helper have identical `Attributes`
- Updated the Razor parser to understand minimized attributes instead of just treating them like plain text. This just involved encompassing minimized attributes in their own blocks just like the other attributes found on the HTML tag.
- Updated TagHelperParseTreeRewriter to only accept minimized attributes for unbound attributes.
- Updated IReadOnlyTagHelperAttribute/TagHelperAttribute to have a Minimized property to indicate that an attribute was minimized.
- Updated parser level block structures to represent minimized attributes as null syntax tree nodes.
- Updated chunk level structures to represent minimized attributes as null chunks.
#220
- related to #89 because we need more descriptor comparers in more places
- separate `TagHelperAttributeDescriptorComparer` and `TypeBasedTagHelperDescriptorComparer`
- encourages reuse and most will soon be used in multiple classes
- add `null` checks to `EquivalenceComparer`
- also give parameters better names
nits:
- use `<inheritdoc/>` in `TagHelperDescriptorComparer`
- also give it an explicit constructor
- make product comparers easier to subclass
- base test `CaseSensitiveTagHelperAttributeDescriptorComparer` on product code
- add `[NotNull]` in some `public` or `protected` callers as well
- add `[NotNull]` in `SeekableTextReader` constructors
- add `where TSymbolType : struct` to replace incorrect `null` checks
- remove `T` type parameters in changed files e.g. change to `TWriter`
- remove tests of removed code
nits:
- change `TextReaderExtensions` to consistently call other extensions as statics
- wrap some long doc comments
- #362 and more
- make a few more properties immutable
- in a few cases, just remove `private` setters
- in others, adjust consuming code to handle the changes
- make `Equals()` commutative
- use `GetType() == obj.GetType()` if necessary
- use only immutable values in `GetHashCode()` calculations
- avoid `object.GetHashCode()`; that calculates hash of reference
- add warnings about `RazorError` property setters but use properties
- BUT lack of immutable values leads to some static `GetHashCode()` calculations
- correct important typo in `TagHelperDescriptorComparer`
- ensure `Equals()` does not `throw` an NRE e.g. in `LineMapping`
- add `SyntaxTreeNode.GetEquivalenceHash()`
- make `SourceLocation.Equals()` and `SourceLocation.CompareTo()` consistent
Update affected tests
- code generators and edit handlers less likely to be equal; adjust expectations
Add lots of tests
- not for all updated classes but enough to see impact of odd choices
nits:
- remove some `Equals()` and `GetHashCode()` overrides in `SpanCodeGenerator` subclasses
- no longer unique
- remove redundant null checks e.g. when also done in `base.Equals()`
- add `StringComparer.Ordinal` if `StringComparison.Ordinal` used in `Equals()`
- make some `CSharpLineMappingWriter` fields `readonly`
- remove unused `LineMapping` constructor
- Added a TagHelperAttributes object that's used to hold 1=>many attributes. Is used for TagHelperOutput.Attributes.
- Added a ReadOnlyTagHelperAttributes object that holds 1=>many IReadOnlyTagHelperAttributes. Is used for TagHelperContext.AllAttributes.
- Added a TagHelperAttribute object which is used to represent attributes.
- Added a IReadOnlyTagHelperAttribute which is used to represent attributes which cannot be modified.
#279
- Existing Razor directives layout, inherits, addTagHelper, tagHelperPrefix and removeTagHelper should only ever span a single line and need to cause a re-parse when a newline is entered during design time. To do this modified their AcceptedCharacters to accept anything other than newline rather than anything.
- Updated existing tests to now expect AcceptedCharacters.AnyExceptNewLine when directives are present.
- This change also enables the model directive in Mvc since it also uses the inherit directives core parsing.
#332
- #320
- `ParserErrorSink` -> `ErrorSink`
- move `ErrorSink`, `RazorError`, and `SourceLocation` to root namespace
- move `RazorErrorTest` and `SourceLocationTest` to root test namespace
- Transitioned HtmlElementNameAttribute into a more generic TargetElementAttribute. Targeting an HTML element can be done by attribute, tag or both.
- Updated TagHelperDescriptor to track required attributes.
- Updated TagHelperProvider to ask for provided attributes when resolving TagHelperDescriptors, this is used to apply RequiredAttributes.
- Updated TagHelperParseTreeRewriter to properly track HTML elements that coincide with a TagHelper scope based on the presence of RequiredAttributes.
#311
- Updated TagHelperDescriptor to have a Prefix property. This enables new tooling scenarios such as refactoring prefixes or even giving them their own classification.
- Added invalid prefix cases.
- Added TagHelperPrefix chunks, codegenerator, parsing logic to flow the directive through the Razor pipeline.
#309
- Errors are only created for TagHelper bound attributes that are not bound to string.
- Added tests to validate proper errors for expected input.
#289
- Added the ability to opt-out of TagHelper parsing by adding a '!' to the beginning of a tag name.
- Modified parsing logic to allow bangs in tags.
- Bangs in tags are removed from output always and are handled as meta code.
#187
- precursor for #129
- remove unused `GeneratorResults` ctor to avoid duplicating `ParserResults` code
nit: make a few `ParserResults` properties immutable
- also change `ParserErrors` type to `IEnumerable<RazorError>`
- Added detection of unclosed tags (tags without begin/end).
- Added recovery of potentially unclosed tags.
- Added detection of invalid structure tags (tags that do not end with '>').
- Modified detection of bad attribute values to be parse errors instead of runtime errors.
- Modified RazorParser to sort errors. This made writing tests more intuitive and ultimately ensures that the editor shows errors in the correct order.
- Added tests to validate invalid tag structure.
- Added tests to validate invalid attributes.
- Added tests to validate unclosed tags.
#104
- We now create LineMappings for instances where a TagHelper's attribute value is not of a string type.
- This will enable the Razor editor to create projections from .cshtml => .cs for TagHelper attributes.
- Modified the TagHelperCodeGenerator and TagHelperBlockBuiler to accurately track the attribute values start locations so it could flow into code generation.
- Modified existing tests to account for the new line mappings.
#207
- Ultimately this enables tooling to inspect what TagHelperDescriptors were found on a document and construct HTML schema based off of them.
- Added XML doc on the classes I touched that didn't have docs.
- Added [NotNull] to the result construct parameters.
- Added tests to validate that TagHelperDescriptors flow when found after parsing a Razor document.
#215
- Also added tests to validate that non string TagHelper attributes inherit the SpanKind.COde behavior.
- Removed a block wrapping around single markup spans.
- Modified existing tests that expected the resolvers to throw to no longer throw.
- Added new test to validate that unexpected errors that are thrown are also handled.
#210
- Changed the TagHelperDescriptorResolver, TagHelperTypeResolver and AddOrRemoveTagHelperSpanVisitor to not throw when they're unable to understand the users directive lookup text.
- This involved utilizing the new ParserErrorSink to capture errors found during TagHelperDescriptor resolution.
#210
- #EngineeringDay
- Total replaced: 506 Matching files: 118
Did not change any files under test/Microsoft.AspNet.Razor.Test/TestFiles
- avoiding need to redo hashes
- Modified the AddOrRemoveTagHelperSpanVisitor to no longer manage TagHelperDescriptors found in the system. Instead it now manages TagHelperDirectiveDescriptors which are then used to resolve TagHelperDescriptors.
- Changed the signature of ITagHelperDescriptorResolver to take in a TagHelperResolutionContext which will allow us to pass more information without breaking tooling.
- TagHelperDescriptorResolver now resolves all TagHelperDescriptors at once and manages descriptors found in the system based on values on the provided TagHelperDirectiveDescriptors.
#214
- Added utility methods to construct valid SyntaxTreeNodes that represent the @removetaghelper directive.
- Added parse level unit tests to validate the @removetaghelper generates an accurate SyntaxTreeNode.
- Added parse level unit tests to validate the @removetaghelper throws with bad formats.
- Added TagHelperRegistration unit tests to validate the AddOrRemoveTagHelperCodeGenerators are understood and affect the descriptors found.
- Added Designtime mapping tests to validate correct source mappings are made to ensure proper coloring and lack-of C# intellisense.
- Added end-to-end tests to validate @removetaghelper can essentially disable TagHelpers on a page.
#112
- Added parsing recognition of the @removetaghelper directive.
- Added TagHelperDescriptor handling: @removetaghelper will cause the system to ignore TagHelpers that are added via @addtaghelper.
- Added Chunk generation, this involved building a CodeGenerator (soon to be named ChunkGenerator) that pulled out the stringified @removetaghelper lookup text which it then uses to construct a RemoveTagHelperChunk.
- Modified CodeVisitors to now understand RemoveTagHelperChunk's.
- Added code generation, this involved creating a dummy string in order to give the @removetaghelper "..." coloring.
#112
- Replaced customer facing Debug.Assert with a new error mechanism to surface errors to GenerateCode callers.
- The new mechanism is a general purpose way for ISyntaxTreeRewriters to add errors to the parsing phase.
#174
- This involved also adding a TagHelperTypeResolver and TagHelperDescriptorFactory.
- The TagHelperTypeResolver is responsible for determining the format of lookup text's used throughout the tag helper system. By default it handles the following formats:
"assemblyName"
"specificType, assemblyName"
- It also restricts what types are considered TagHelpers. In this implementation we only accept public, non-nested, non-abstract, non-generic TagHelpers.
- The TagHelperDescriptorFactory is responsible for converting a Type to a TagHelperDescriptor.
- Added tests to validate TagHelperDescriptorResolver, TagHelperTypeResolver and TagHelperDescriptorFactory.
#99#158
- Also added some infrastructure pieces for it such as the ITagHelperDescriptorResolver and the default implementation TagHelperDescriptorResolver which will be filled out in a later commit.
- Reworked some extensibility points to allow accessibility of the descriptor resolvers per offline discussions.
#111
- Added TagHelperChunk generation.
- Added CSharp visitors to understand TagHelperChunks and render corresponding C# code.
- Refactored some code in the CSharpCodeVisitor so it could be utilized in other classes.
- Added a CSharpFieldDeclarationVisitor to render declaration pieces for TagHelper's
- Added metadata to represent specific TagHelper code generation constructs.
#72
- The visitor looks for TagBlock's that match registered TagHelpers and rebuilds them into TagHelperBlock's.
- Added the code generator and corresponding chunk for a TagHelperBlock.
- Added syntax tree specific objects & helper methods to create accurate tag helper structures.
#71
This is a perf improvement of about 500ms for our razor code generation
benchmark on my dev box. That's about .8% of the overall execution time of
this benchmark.
This change will remove a bunch of unnessary allocations from the
parsing/code-generation path, and should improve responsiveness.
For reference Enum.HasFlags performs boxing of the enum value, and then
does a type comparison to see if the types are the same. This is
significantly more costly than a normal bitwise and comparison, and it
results in allocations.
.NET FX Team will not be adding Char.GetUnicodeCategory because it breaks layering. We cannot have a dependency form System.Runtime.dll to System.Globalization.dll.
