If not, see . - -;;; Commentary: -;; -;; This file handles the creation of lexical analyzers for different -;; languages in Emacs Lisp. The purpose of a lexical analyzer is to -;; convert a buffer into a list of lexical tokens. Each token -;; contains the token class (such as 'number, 'symbol, 'IF, etc) and -;; the location in the buffer it was found. Optionally, a token also -;; contains a string representing what is at the designated buffer -;; location. -;; -;; Tokens are pushed onto a token stream, which is basically a list of -;; all the lexical tokens from the analyzed region. The token stream -;; is then handed to the grammar which parsers the file. -;; -;;; How it works -;; -;; Each analyzer specifies a condition and forms. These conditions -;; and forms are assembled into a function by `define-lex' that does -;; the lexical analysis. -;; -;; In the lexical analyzer created with `define-lex', each condition -;; is tested for a given point. When the conditin is true, the forms -;; run. -;; -;; The forms can push a lexical token onto the token stream. The -;; analyzer forms also must move the current analyzer point. If the -;; analyzer point is moved without pushing a token, then tne matched -;; syntax is effectively ignored, or skipped. -;; -;; Thus, starting at the beginning of a region to be analyzed, each -;; condition is tested. One will match, and a lexical token might be -;; pushed, and the point is moved to the end of the lexical token -;; identified. At the new position, the process occurs again until -;; the end of the specified region is reached. -;; -;;; How to use semantic-lex -;; -;; To create a lexer for a language, use the `define-lex' macro. -;; -;; The `define-lex' macro accepts a list of lexical analyzers. Each -;; analyzer is created with `define-lex-analyzer', or one of the -;; derivitive macros. A single analyzer defines a regular expression -;; to match text in a buffer, and a short segment of code to create -;; one lexical token. -;; -;; Each analyzer has a NAME, DOC, a CONDITION, and possibly some -;; FORMS. The NAME is the name used in `define-lex'. The DOC -;; describes what the analyzer should do. -;; -;; The CONDITION evaluates the text at the current point in the -;; current buffer. If CONDITION is true, then the FORMS will be -;; executed. -;; -;; The purpose of the FORMS is to push new lexical tokens onto the -;; list of tokens for the current buffer, and to move point after the -;; matched text. -;; -;; Some macros for creating one analyzer are: -;; -;; define-lex-analyzer - A generic analyzer associating any style of -;; condition to forms. -;; define-lex-regex-analyzer - Matches a regular expression. -;; define-lex-simple-regex-analyzer - Matches a regular expressions, -;; and pushes the match. -;; define-lex-block-analyzer - Matches list syntax, and defines -;; handles open/close delimiters. -;; -;; These macros are used by the grammar compiler when lexical -;; information is specified in a grammar: -;; define-lex- * -type-analyzer - Matches syntax specified in -;; a grammar, and pushes one token for it. The * would -;; be `sexp' for things like lists or strings, and -;; `string' for things that need to match some special -;; string, such as "\\." where a literal match is needed. -;; -;;; Lexical Tables -;; -;; There are tables of different symbols managed in semantic-lex.el. -;; They are: -;; -;; Lexical keyword table - A Table of symbols declared in a grammar -;; file with the %keyword declaration. -;; Keywords are used by `semantic-lex-symbol-or-keyword' -;; to create lexical tokens based on the keyword. -;; -;; Lexical type table - A table of symbols declared in a grammer -;; file with the %type declaration. -;; The grammar compiler uses the type table to create new -;; lexical analyzers. These analyzers are then used to when -;; a new lexical analyzer is made for a language. -;; -;;; Lexical Types -;; -;; A lexical type defines a kind of lexical analyzer that will be -;; automatically generated from a grammar file based on some -;; predetermined attributes. For now these two attributes are -;; recognized : -;; -;; * matchdatatype : define the kind of lexical analyzer. That is : -;; -;; - regexp : define a regexp analyzer (see -;; `define-lex-regex-type-analyzer') -;; -;; - string : define a string analyzer (see -;; `define-lex-string-type-analyzer') -;; -;; - block : define a block type analyzer (see -;; `define-lex-block-type-analyzer') -;; -;; - sexp : define a sexp analyzer (see -;; `define-lex-sexp-type-analyzer') -;; -;; - keyword : define a keyword analyzer (see -;; `define-lex-keyword-type-analyzer') -;; -;; * syntax : define the syntax that matches a syntactic -;; expression. When syntax is matched the corresponding type -;; analyzer is entered and the resulting match data will be -;; interpreted based on the kind of analyzer (see matchdatatype -;; above). -;; -;; The following lexical types are predefined : -;; -;; +-------------+---------------+--------------------------------+ -;; | type | matchdatatype | syntax | -;; +-------------+---------------+--------------------------------+ -;; | punctuation | string | "\\(\\s.\\|\\s$\\|\\s'\\)+" | -;; | keyword | keyword | "\\(\\sw\\|\\s_\\)+" | -;; | symbol | regexp | "\\(\\sw\\|\\s_\\)+" | -;; | string | sexp | "\\s\"" | -;; | number | regexp | semantic-lex-number-expression | -;; | block | block | "\\s(\\|\\s)" | -;; +-------------+---------------+--------------------------------+ -;; -;; In a grammar you must use a %type expression to automatically generate -;; the corresponding analyzers of that type. -;; -;; Here is an example to auto-generate punctuation analyzers -;; with 'matchdatatype and 'syntax predefined (see table above) -;; -;; %type ;; will auto-generate this kind of analyzers -;; -;; It is equivalent to write : -;; -;; %type syntax "\\(\\s.\\|\\s$\\|\\s'\\)+" matchdatatype string -;; -;; ;; Some punctuations based on the type defines above -;; -;; %token NOT "!" -;; %token NOTEQ "!=" -;; %token MOD "%" -;; %token MODEQ "%=" -;; - -;;; On the Semantic 1.x lexer -;; -;; In semantic 1.x, the lexical analyzer was an all purpose routine. -;; To boost efficiency, the analyzer is now a series of routines that -;; are constructed at build time into a single routine.
