#lang racket/base #| Check Syntax separates two classes of identifiers, those bound in this file and those bound by require, and uses identifier-binding and identifier-transformer-binding to distinguish them. Variables come from 'origin, 'disappeared-use, and 'disappeared-binding syntax properties, as well as from variable references and binding (letrec-values, let-values, define-values) in the fully expanded text. Variables inside #%top (not inside a module) are treated specially. If the namespace has a binding for them, they are colored bound color. If the namespace does not, they are colored the unbound color. |# (require string-constants racket/unit racket/contract racket/class racket/list racket/promise racket/pretty racket/dict data/interval-map drracket/tool syntax/toplevel syntax/boundmap mrlib/switchable-button (prefix-in drracket:arrow: drracket/arrow) (prefix-in fw: framework/framework) mred framework setup/xref scribble/xref scribble/manual-struct net/url net/uri-codec browser/external (for-syntax racket/base) "../../syncheck-drracket-button.rkt" "intf.rkt" "colors.rkt" "traversals.rkt") (provide tool@) (define orig-output-port (current-output-port)) (define (oprintf . args) (apply fprintf orig-output-port args)) (define status-init (string-constant cs-status-init)) (define status-coloring-program (string-constant cs-status-coloring-program)) (define status-eval-compile-time (string-constant cs-status-eval-compile-time)) (define status-expanding-expression (string-constant cs-status-expanding-expression)) (define jump-to-next-bound-occurrence (string-constant cs-jump-to-next-bound-occurrence)) (define jump-to-binding (string-constant cs-jump-to-binding)) (define jump-to-definition (string-constant cs-jump-to-definition)) (define cs-check-syntax-mode (string-constant cs-check-syntax-mode)) (define cs-mode-menu-show-my-obligations (string-constant cs-mode-menu-show-my-obligations)) (define cs-mode-menu-show-client-obligations (string-constant cs-mode-menu-show-client-obligations)) (define cs-mode-menu-show-syntax (string-constant cs-mode-menu-show-syntax)) (preferences:set-default 'drracket:syncheck-mode 'default-mode (λ (x) (memq x '(default-mode my-obligations-mode client-obligations-mode)))) (define tool@ (unit (import drracket:tool^) (export drracket:tool-exports^) (define (phase1) (drracket:module-language-tools:add-opt-out-toolbar-button (λ (frame parent) (new switchable-button% (label (string-constant check-syntax)) (bitmap syncheck-bitmap) (parent parent) (callback (λ (button) (send frame syncheck:button-callback))))) 'drracket:syncheck) (drracket:unit:add-to-program-editor-mixin clearing-text-mixin)) (define (phase2) (void)) ;;; ;;; ;;; ;;;;; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ;; ; ; ; ; ; ; ; ; ; ; ;; ;; ; ;;; ;;; ;;;;; ;; used for quicker debugging of the preference panel '(define test-preference-panel (λ (name f) (let ([frame (make-object frame% name)]) (f frame) (send frame show #t)))) (define-struct graphic (pos* locs->thunks draw-fn click-fn)) (define-struct arrow (start-x start-y end-x end-y) #:mutable) (define-struct (var-arrow arrow) (start-text start-pos-left start-pos-right end-text end-pos-left end-pos-right actual? level)) ;; level is one of 'lexical, 'top-level, 'import (define-struct (tail-arrow arrow) (from-text from-pos to-text to-pos)) ;; color : string ;; text: text:basic<%> ;; start, fin: number ;; used to represent regions to highlight when passing the mouse over the syncheck window (define-struct colored-region (color text start fin)) ;; id : symbol -- the nominal-source-id from identifier-binding ;; filename : path (define-struct def-link (id filename) #:inspector (make-inspector)) (define tacked-var-brush (send the-brush-list find-or-create-brush "BLUE" 'solid)) (define var-pen (send the-pen-list find-or-create-pen "BLUE" 1 'solid)) (define templ-color (send the-color-database find-color "purple")) (define templ-pen (send the-pen-list find-or-create-pen templ-color 1 'solid)) (define tacked-templ-brush (send the-brush-list find-or-create-brush templ-color 'solid)) (define tail-pen (send the-pen-list find-or-create-pen "orchid" 1 'solid)) (define tacked-tail-brush (send the-brush-list find-or-create-brush "orchid" 'solid)) (define untacked-brush (send the-brush-list find-or-create-brush "WHITE" 'solid)) ;; clearing-text-mixin : (mixin text%) ;; overrides methods that make sure the arrows go away appropriately. ;; adds a begin/end-edit-sequence to the insertion and deletion ;; to ensure that the on-change method isn't called until after ;; the arrows are cleared.
