- Added case in ImplicitExpression handling to understand question marks.
- text?. is special compared to text. because with text. we currently validate content after text. to determine if it's an expression or if it's a period. Now with ?. we always treat it as an expression because ?. is not a useful sentance of any kind.
- Added unit tests to validate new implicit expression handling
- Added runtime and design time code generation tests to validate null conditional operators.
#44
- Involved updating the HtmlMarkupParser to properly separate data- attributes. Prior to this change `data-foo="abc @DateTime.Now def"` would involve 1 Span for `data-foo="abc` 1 Span for `@DateTime.Now` and 1 Span for `def"`. This was very unique behavior from an attribute standpoint (as far as Razor is concerned) and made it difficult for the TagHelper rewriting system to rewrite attributes. With this change it gets broken out as follows: `|data-foo="|abc| @DateTime.Now| def|"|`.
- Added unit tests to validate the various ways you can write unbound data- attributes.
- Updated the BasicTagHelpers codegeneration test to intermix some unbound data- attributes.
#342
- 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
- #182
- ignore otherwise-bound (i.e. `public`) properties in tag helpers
nits:
- add more `TagHelperDescriptorFactory` tests e.g. of `internal` properties
- remove `private` setter from `HtmlAttributeNameAttribute`
- use `null` propagation to shorten `IsAccessibleProperty` expression
- clean up some trailing whitespace
- 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
- These two new properties will enable TagHelper authors to render content before and after the TagHelper's HTML element.
- Added tests to correspond with existing test coverage.
- Modified existing tests to double check for TagHelperOutput.Pre/PostElement.
- Refactored all DefaultTagHelperContent pieces of TagHelperOutput to be get only properties.
#341
- #320
- `ParserErrorSink` -> `ErrorSink`
- move `ErrorSink`, `RazorError`, and `SourceLocation` to root namespace
- move `RazorErrorTest` and `SourceLocationTest` to root test namespace
- Normalized newlines for code generation tests. We default all tests to use \r\n. This way we can have a consistent test experience cross plat.
- For tests that expected indexes that were affected by new lines I modified them to account for cross plat scenarios.
- Added a few test classes to ensure we could normalize newlines for codegen tests.
#106
- #335
- bound `string` attribute values are _not_ encoded
- rework `CSharpCodeVisitor` and `CSharpTagHelperCodeRenderer` to enable this case
- values in `TagHelperOutput.Attributes` are encoded unless special-cased elsewhere
- `Dictionary<string, object>` type allows `RazorPage` to use `HtmlString`
- wrap HTML unbound attribute values using `Html.Raw()`
- This can occur if you have multiple [TargetElement] attributes that overlap. Ultimately the descriptor is the same because its the same type, just the required attributes differ.
- Added tests to validate.
#326
- 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
- Add a an Item properties on TagHelperExecutionContext to propagate to the TagHelperContext.
- Updated TagHelperScopeManager to create CopyOnWriteDictionary item bags for created TagHelperExecutionContexts.
#238
- 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
- @addtaghelper and @removetaghelper can now utilize the '*' wild card to represent 0 or more characters.
- Restricted the @addtaghelper to need the TypeName. @addtaghelper "MyAssemblyName" => @addtaghelper "*, MyAssemblyName".
#285
- Modified the CSharpTagHelperCodeRenderer to understand a single line of TagHelper rendering (instead of doing different things based on ContentBehavior).
- Modified existing CodeGen output to reflect new content changes.
#221
- Added PreContent, PostContent and ContentSet properties to TagHelperOutput.
- Added GeneratePreContent, GeneratePostContent and SupressOutput methods to TagHelperOutput.
- Added multile ExecuteChildContentAsync and GetChildContentAsync to the rendering phase, ultimately only exposing GetChildContentAsync to a TagHelper author.
- Added more knowledge of StartWritingScope and EndWritingScope to the TagHelper runtime components. This is to enable the runtime components to utilize the RazorPage's infrastructure to render a delegate to a writer and retrieve its value to ultimately expose it to the user.
#221
- Removed all tests and instances of ContentBehavior in preparation for moving to a non-ContentBehavior based design.
- Removed ContentBehavior specific CodeGeneration.
#221
- #129 and support aspnet/Mvc#1253
- add new `CSharpTagHelperAttributeValueVisitor` that writes the raw expression
- add tests of embedded `@(...)` and mix that with normal expressions
- add new resources for errors in `CSharpTagHelperAttributeValueVisitor`
- write errors using `ParserErrorSink`
- update baselines to match new code generation
nits:
- cleanup long lines in `CSharpTagHelperCodeRenderer`
- remove a few unused resources
- add `ToString()` overrides for these classes
Nits:
- improve assertion failures about code mapping mismatches
- add `GENERATE_BASELINES` reminder to test project.json
- 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 a 0414 warning disable/restore around the __tagHelperStringValueBuffer since it's the only TagHelper utility field that "may" never be used.
- Regenerated baselines for TagHelper test files.
#260
- 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
- The ID is created at view compilation time and is unique per TagHelperExecutionContext and thus per HTML element in the source for which Tag Helpers will run
- #241
- 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
- Updated all of the tests to use the new ITagHelperDescriptorResolver signature so instead of passing strings they now construct TagHelperDescriptorResolutionContexts.
- Removed several tests from the AddOrRemoveTagHelperSpanVisitorTests. This was due to the change in responsibility of managing the found TagHelperDescriptors; the TagHelperDescriptorResolver now does this.
- Added several new tests to verify the TagHelperDescriptorResolver manages resolved TagHelperDescriptors based on the given TagHelperDirectiveDescriptors.
#214
- 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
- Modified our default TagHelperDescriptorResolver to provide a protected virtual method that it uses under the covers to resolve descriptors for an entire assembly. This will enable tooling to cache descriptors on a per-assembly basis.
#214
- Right now the only information that is used from the PropertyInfo is the PropertyName and the PropertyType, therefore changed the PropertyInfo property on TagHelperAttributeDescriptor to be AttributeTypeName since we already had an accessor for AttributePropertyName.
- Modified test comparers to validate type names.
#214
- TagHelperDescriptor's need a way to showcase where they came from so tooling can reverse look them up.
- Update tests to specify TagHelperDescriptor assembly names.
#214
- We now generate a subset of the TagHelper runtime code during DesignTime. This enables users to see errors in the editor
- Added tests to validate design time code generation.
- Refactored runtime code generation tests (we now use a lot of their infrastructure for the design time pieces).
#208
- 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
- Changed the Attributes dictionary to utilize a StringComparer.OrdinalIgnoreCase comparer.
- Changed TagHelperExecutionContext to ignore attribute casing.
- Updated the AllAttributes and HtmlAttributes dictionaries to ignore attribute casing.
- Added tests to validate their new behavior.
#186
- Whenever we encounter an @addtaghelper directive we add it to the CodeTree at the top level (not nested in any chunk blocks).
- Added a test to validate that @addtaghelper inside of a ChunkBlock doesn't add to the ChunkBlock's children.
#195.
- Added the ability to override the HTML attribute name for TagHelper properties.
- Tested functionality of overriding the attribute name target and inheriting the attribute name.
#121
- Used to only look at declared properties on the tag helper type, now we get the runtime properties.
- Fixed Runtime test projec to work with new CLR changes (looks like it was missed).
#189
- 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
- Made it so the TagHelperDescriptorFactory could pull tag name targets from TagNameAttributes on types.
- Tested the behavior between TagNameAttribute and TagHelperDescriptorFactory (the only consumer of the attribute).
- Made sure to test duplicate and inherited class scenarios.
#120
- Added detection of custom ContentBehaviors via the ContentBehaviorAttribute in the TagHelperDescriptorFactory.
- Updated some comments in the ContentBehavior enum.
- Add tests to validate custom content behavior resolution.
#122
- This involved adding the following core classes: TagHelper, TagHelperExecutionContext, TagHelperOutput, TagHelperContext. All of which aid in running TagHelpers.
#154
- 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
- Enabled the CSharpCodeBuilder to create the CSharpCodeVisitor which exposes a CSharpTagHelperCodeRenderer which is indirectly used to render attribute values.
- Fixed up some existing classes that just new'd up the CSharpCodeVisitor class to instead take in the decorated version.
#119
- 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.
These types are allocated for every state transition in the parser (State)
or every character that's read (character reference) and are fairly
compact. Turning them into structs will remove a significant number of unnecessary
allocations in the parser.
For our razor code generation benchmark, making these changes yields about
500-750ms of speedup (out of 40000ms) or about 1%.
- This registration system accepts tag descriptors that it then uses to feed requests for tag helpers.
- Added some infrastructure pieces that are used to build up valid tag helper descriptors.
#70
GetSourceLocation is frequently called to determine the location mappings
between the original document and the generated code.
The old implementation did a number of ToString and replace operations to
simplify the math on tracking the position - which put it front and center
in our performance measurements - about 25% of all execution time in a
sampling profile of our perf test.
The new code tracks position as code is written, and avoids allocations.
After these changes GetSourceLocation doesn't show up in the profile.
This extensibility point needs to be an override and not a pure visitor due to how the class declaration is created (only 1 right way to write the class).
#76
Removed all System.CodeDOM related code from net45. This involved modifying some existing code paths and most of all reducing the complexity of all of the CodeGenerators. Added some factory creation methods to build CodeBuilders. Ran code analysis and made adjustments to pass analysis.
Added newlines inbetween ending line pragma's and code. Without the extra line the document does not format correctly. Separated expression and statement padding functionality. Statements need to have 1 less padding to account for the transition. Changed how runtime and design time code generates to enable accurate debugging experiences in runtime and functional formatting experiences during design time.
This allows for users to write "@using System;" and still have proper intellisense and mapping. Also removed some legacy code that I came across when running tests.
.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.
Added a CSharpPaddingBuilder based on the existing
CodeGeneratorPaddingHelper to allow accurate padding within the generated
C# files. Also created tests based on the existing PaddingTest tests to
verify padding functionality.
This involved adding more boiler plate to the base of the visitor classes such as a Writer and a Context. By following this contract for new visitors we'll ensure that visitors have enough information to add new features to Razor.
Without the initial code tree acceptance you end up stack overflowing. Also removed a validation check that ensures that there's always a base type (not true).
This addition will eventually replace CodeDOM to allow for the k10 project to build. It is a new type of codegeneration method that is highly extensible.
