Rather than creating an Abstract Syntax Tree, I create a sequence of SHRanges (in my 'ranges' instance variable), which represent the tokens within the String I am parsing. I am used by a SHTextStylerST80 to parse method source strings. I am able to parse incomplete / incorrect methods, and so can be used to parse methods that are being edited. Instance Variables allowBlockArgumentAssignment: <Boolean> allowUnderscoreAssignments: <Boolean> allowUnderscoreSelectors: <Boolean> arguments: <OrderedCollection<OrderedCollection<String>|nil> bracketDepth: <Integer> classOrMetaClass: <Class|nil> currentToken: <String|nil> currentTokenFirst: <Character> currentTokenSourcePosition: <Integer|nil> currentTokenType: <Symbol|nil> environment: <Environment> errorBlock: <Block> instanceVariables: <Array> parseAMethod: <Boolean> ranges: <OrderedCollection<SHRange>> source: <String> sourcePosition: <Integer> temporaries: <OrderedCollection<OrderedCollection<String>|nil> workspace: <Workspace|nil> + context: <Context|nil> allowBlockArgumentAssignment The value cached at the beginning of parsing of Scanner allowBlockArgumentAssignment. allowUnderscoreAssignments The value cached at the beginning of parsing of Scanner allowUnderscoreAsAssignment. allowUnderscoreSelectors The value cached at the beginning of parsing of Scanner prefAllowUnderscoreSelectors. arguments This OrderedCollection has an element for each scope encapsulating the current scope. The current scope's arguments are stored in the last element. The first element holds the outermost scope's arguments. Each element is nil when the corresponding scope doesn't have any arguments, and the element is an OrderedCollection with the names of the arguments declared at the given scope when there's at least one. The size of this variable is the same as the size of temporaries. bracketDepth Stores the number of unclosed brackets "(" and parentheses "[" before the current sourcePosition. classOrMetaClass The Class or MetaClass instance, class and pool variables should be looked up during parsing or nil when not parsing code in the context of a class (e.g. when parsing code written in a Workspace). Having this set doesn't mean a method is being parsed. currentToken The token being analyzed for which the next range should be created for. currentTokenFirst The first character of currentToken cached for quick access or a space character when there are no more tokens to parse. Being always a Character helps avoiding extra checks. currentTokenSourcePosition The position of source the current token starts at or nil when there are no more tokens to process. currentTokenType The type of the current token calculated lazily by #currentTokenType. When it has been calculated, Its value is one of #keyword, #assignment, #ansiAssignment, #binary, #name, #other and occasionally #invalid. environment The Environment globals and classes should be looked up at during parsing when classOrMetaClass is nil. Its value is Smalltalk globals by default. errorBlock A block used to quickly stop parsing in case of an unrecoverable parse error. instanceVariables An Array with the instance variable names of classOrMetaClass or an empty Array when classOrMetaClass is nil. parseAMethod A way to tell the parser to parse source as a code snippet instead of a method. Mainly used by inspectors. ranges The SHRanges parsed by the parser. source The source code as a String to be parsed. sourcePosition souce is treated as a stream by the parser. This variable stores the stream position. temporaries This OrderedCollection has an element for each scope encapsulating the current scope. The current scope's temporaries are stored in the last element. The first element holds the outermost scope's temporaries. Each element is nil when the corresponding scope doesn't have any temporary variables, and the element is an OrderedCollection with the names of the temporaries declared at the given scope when there's at least one. The size of this variable is the same as the size of arguments. workspace The Workspace in whose context variables should be looked up during parsing or nil when not parsing code in a workspace. + context + The Context in which variables should be looked up during parsing or nil when not parsing within a context. Example (explore it): ranges := SHParserST80 new classOrMetaClass: Object; source: 'testMethod ^self'; parse; ranges Benchmark (print it): SHParserST80 benchmark!

I style Smalltalk methods and expressions. My 'styleTable' class instance var holds an array ofArrays which control how each token is styled/coloured. See my defaultStyleTable class method for its structure. My styleTable can be changed by either modifying the defaultStyleTable class method and then executing SHTextStylerST80 initialize ; or by giving me a new styleTable through my #styleTable: class method. My 'textAttributesByPixelSize' class instance var contains a dictionary of dictionaries. The key is a pixelSize and the value a Dictionary from token type Symbol to TextAttribute array. It is created/maintained automatically. I also install these 3 preferences when my class initialize method is executed.... #syntaxHighlightingAsYouType - controls whether methods are styled in browsers #syntaxHighlightingAsYouTypeAnsiAssignment - controls whether assignments are formatted to be := #syntaxHighlightingAsYouTypeLeftArrowAssignment - controls whether assignments are formatted to be _ I reimplement #unstyledTextFrom: so that TextActions are preserved in the unstyled text !
