An apropos facility for Chicken Scheme.
apropos[procedure] (apropos PATTERN [ENVIRONMENT] [#:macros? MACROS?] [#:qualified? QUALIFIED?] [#:sort SORT])
Displays information about identifiers matching PATTERN in the ENVIRONMENT and, optionally, a MACRO-ENVIRONMENT.
- A symbol, string or regexp. When symbol or string substring matching is performed.
- An environment. The default is the (interaction-environment).
- Either #t to include macros, or #f to skip them. Default is #f.
- Either #t to include qualified identifiers or #f to skip them. Default is #f.
- Either #:name for an identifier sort, or #:kind for a kind+indentifier sort, or #f for unsorted. The default is #:kind.
apropos-list[procedure] (apropos-list PATTERN [ENVIRONMENT] [#:macros? MACROS?] [#:qualified? QUALIFIED?])
Like apropos but returns a list of matching identifiers.
apropos-information-list[procedure] (apropos-information-list PATTERN [ENVIRONMENT] [#:macros? MACROS?] [#:qualified? QUALIFIED?] [#:sort? SORT?])
Like apropos but returns an association list keyed by symbol. The associated information is either 'macro, 'keyword, 'variable, 'procedure, '(procedure . <lambda-list-specification>) or '(procedure . <core procedure name>).
(require-library apropos) (import apropos)
(require-extension apropos) (import apropos)
Bugs and Limitations
- Doesn't show something similar to procedure-information for macros.
- Chicken 4 release.
