8 Interface for Clients of Syntax Color Output
| (require syntax-color/color-textoid) | |
| package: syntax-color-lib | |
Added in version 1.3 of package syntax-color-lib.
|
The color-textoid<%> interface matches a subset of the
color:text<%> interface. It specifies methods that
indentation and expression-navigation functions can use so that they
work either on actual color:text<%> objects or in other
environments that use the start-colorer in color:text<%>
protocol without racket/gui.
method
start : exact-nonnegative-integer? = 0 end : (or/c exact-nonnegative-integer? 'eof) = 'eof
method
(send a-color-textoid get-character start) → char?
start : exact-nonnegative-integer? Like get-character in text%.
method
(send a-color-textoid last-position)
→ exact-nonnegative-integer? Like last-position in text%.
method
(send a-color-textoid position-paragraph start [ at-eol?]) → exact-nonnegative-integer? start : exact-nonnegative-integer? at-eol? : any/c = #f Like position-paragraph in text%.
method
(send a-color-textoid paragraph-start-position paragraph [ visible?]) → exact-nonnegative-integer? paragraph : exact-nonnegative-integer? visible? : any/c = #t Like paragraph-start-position in text%.
method
(send a-color-textoid paragraph-end-position paragraph [ visible?]) → exact-nonnegative-integer? paragraph : exact-nonnegative-integer? visible? : any/c = #t Like paragraph-end-position in text%.
method
(send a-color-textoid skip-whitespace position direction comments?) → exact-nonnegative-integer? position : exact-nonnegative-integer? direction : (or/c 'forward 'backward) comments? : boolean? Like skip-whitespace in color:text<%>.
method
(send a-color-textoid backward-match position cutoff) → (or/c exact-nonnegative-integer? #f) position : exact-nonnegative-integer? cutoff : exact-nonnegative-integer? Like backward-match in color:text<%>.
method
(send a-color-textoid backward-containing-sexp position cutoff) → (or/c exact-nonnegative-integer? #f) position : exact-nonnegative-integer? cutoff : exact-nonnegative-integer? Like backward-containing-sexp in color:text<%>.
method
(send a-color-textoid forward-match position cutoff) → (or/c exact-nonnegative-integer? #f) position : exact-nonnegative-integer? cutoff : exact-nonnegative-integer? Like forward-match in color:text<%>.
method
(send a-color-textoid classify-position position)
→ (or/c symbol? #f) position : exact-nonnegative-integer? Like classify-position in color:text<%>.
method
(send a-color-textoid classify-position* position)
→ (or/c (and/c (hash/c symbol? any/c) immutable?) #f) position : exact-nonnegative-integer? Like classify-position* in color:text<%>.
method
(send a-color-textoid get-token-range position)
→
(or/c #f exact-nonnegative-integer?) (or/c #f exact-nonnegative-integer?) position : exact-nonnegative-integer? Like get-token-range in color:text<%>.
method
(send a-color-textoid get-backward-navigation-limit start)
→ exact-integer? start : exact-integer?
method
(send a-color-textoid get-regions)
→ (listof (list/c exact-nonnegative-integer? (or/c exact-nonnegative-integer? 'end))) Like get-regions in color:text<%>.
