I scan a string or text, picking out Smalltalk syntactic tokens. I look one character ahead. I put each token found into the instance variable, token, and its type (a Symbol) into the variable, tokenType. At the end of the input stream, I pretend to see an endless sequence of special characters called doIts. Instance Variables aheadChar: <Character> buffer: <WriteStream> currentComment: <OrderedCollection> hereChar: <Character> mark: <Integer> source: <ReadStream> token: <Symbol|String|NumberCharacter|Boolean|nil> tokenType: <Symbol> typeTable: <Array> aheadChar - the next character in the input stream buffer - a reusable WriteStream on a String which is used for building strings. Shouldn't be used from multiple methods without resetting. currentComment - an OrderedCollection of strings which contain all comments between the current token and the previous token or the beginning of the source. hereChar - the current character mark - the position of the current token in the source stream source - the input stream of characters token - the current token tokenType - the type of the current token. The possible token types are: #binary, #character, #colon, #doIt, #keyword, #leftArrow, #leftBrace, #leftBracket, #leftParenthesis, #literal, #period, #rightBrace, #rightBracket, #rightParenthesis, #semicolon, #string, #upArrow, #verticalBar, #word, #xBinary, #xColon, #xDelimiter, #xDigit, #xDollar, #xDoubleQuote, #xLetter, #xLitQuote, #xSingleQuote, #xUnderscore typeTable - an array that maps each an evaluable tokenType to each character with asciiValue between 0 and 255!

OSProcess on Windows
by Chris Muller 09 Jun '11

09 Jun '11

After a long time working solely in Linux, I seem to be confused about how to configure an image on Windows with OSProcess. I'm running a recent Cog VM (2382, April 26 2011) and have Win32OSProcessPlugin.dll is in my VM directory, but I don't have any of the Plugin classes in my image. When I try to load OSProcessPlugin from SqueakMap, it halts saying it wants InterpreterPlugin to be able to install OSProcessPlugin and subclasses.. What is the proper way to install OSProcess on Windows? Thanks, Chris

"baseRepo" is misleading, this temp should be named "baseVersion". Perhaps even make a method "baseVersion" and use it here? > Item was changed: > ----- Method: MCHttpRepository>>allFileNames (in category 'required') ----- > allFileNames > | index | > + [self displayProgress: 'Updating ', self description during:[ > - self displayProgress: 'Updating ', self description during:[ > index := HTTPSocket httpGet: self locationWithTrailingSlash, '?C=M;O=D' args: nil user: self user passwd: self password. > + ]] on: NetworkError do: [ :e | self error: 'Could not access ', location, '(', e className, ')']. > - ]. > index isString ifTrue: [self error: 'Could not access ', location]. > ^ self parseFileNamesFromStream: index ! - Bert -
