A number of minor features are listed in the following format:

Annotate your implementation with @ExtensionImpl. - Registration approach for the extension point

com.extensionPoint.class description text - Extension Point class/interface to provide functionality

- Sample 1 - Sample implementation

Brace Matching

Annotate your implementation with @ExtensionImpl.

PairedBraceMatcher Returns an array of brace pairs (BracePair) specifying the characters for the opening and closing braces and the lexer token types for these characters. (In principle, it is possible to return multi-character tokens, like "begin" and "end", as the start and end tokens of a brace pair. The IDE will match such braces, but the highlighting for such braces will not be entirely correct.)

Certain types of braces can be marked as structural. Structural braces have higher priority than regular braces: they are matched with each other even if there are unmatched braces of different types between them. An opening non-structural brace is not matched with a closing one if one of them is inside a pair of matched structural braces and another is outside.

Comment Code

Annotate your implementation with @ExtensionImpl.

Commenter (consulo.language.Commenter) returns the prefix for the line comment, and the prefix and suffix for the block comment if supported by the language.

• Commenter for Properties language plugin
• Custom Language Support Tutorial: Commenter

Code Folding

Annotate your implementation with @ExtensionImpl.

FoldingBuilder (consulo.language.editor.folding.FoldingBuilder) returns the list of foldable text ranges (as an array of FoldingDescriptor (consulo.language.editor.folding.FoldingDescriptor) objects), the replacement text which is shown for each range when it is folded, and the default state of each folding region (folded or unfolded).

Join Lines

Annotate your implementation with @ExtensionImpl.

JoinLinesHandlerDelegate allows extending support smart/semantic Edit | Join Lines (e.g., String literal split on multiple lines).

Smart Enter

Annotate your implementation with @ExtensionImpl.

SmartEnterProcessor handles Edit | Complete Statement (e.g., autocomplete missing semicolon/parentheses).

Naming Suggestions

Annotate your implementation with @ExtensionImpl.

NameSuggestionProvider provides name suggestions for the given element, e.g., for Rename refactoring.

Semantic Highlight Usages

Annotate your implementation with @ExtensionImpl.

HighlightUsagesHandlerFactory allows highlighting e.g., Exit Points or Exceptions.

Parameter Info

Annotate your implementation with @ExtensionImpl.

ParameterInfoHandler provides support for View | Parameter Info.

To Do View

EP: n/a

ParserDefinition.getCommentTokens() must return the set of tokens treated as comments to populate To Do View.

Context Info

Annotate your implementation with @ExtensionImpl.

DeclarationRangeHandler provides View | Context Info for custom languages with structure view implementation based on a TreeBasedStructureViewBuilder (consulo.fileEditor.structureView.TreeBasedStructureViewBuilder).

Spellchecking

Annotate your implementation with @ExtensionImpl.

SpellcheckingStrategy provides Tokenizer to use for given PsiElement (return EMPTY_TOKENIZER for no spellchecking).

Reference Injection

Annotate your implementation with @ExtensionImpl.

ReferenceInjector allows users to inject pre-defined references (e.g., "Encoding", "File Reference") into PsiLanguageInjectionHost elements (Language Injection plugin required).

Color Preview/Chooser

Annotate your implementation with @ExtensionImpl.

ElementColorProvider renders gutter icon for element containing color information.
