18.4 Interaction Configuration
| (require racket/interaction-info) | package: base |
The bindings documented in this section are provided by the racket/interaction-info library, not racket/base or racket.
The racket/interaction-info library provides a way to register a langauge’s configuration for a read-eval-print loop and editor.
parameter
→ (or/c #f (vector/c module-path? symbol? any/c)) (current-interaction-info info) → void? info : (or/c #f (vector/c module-path? symbol? any/c))
A parameter that provides configuration for a language for use
by interactive development tools, such as a command-line evaluation
prompt with syntax coloring and indentation support. This parameter is
typically set by a configure-runtime module; see also
Language Run-Time Configuration.
Instead of providing configuration information directly, the the current-interaction-info parameter specifies a module to load, a exported function to call, and data to pass as an argument to the exported function. The result of that function should be another one that accepts two arguments: a symbol a symbol indicating the kind of information requested (as defined by external tools), and a default value that normally should be returned if the symbol is not recognized.
For information on defining a new #lang language, see syntax/module-reader.
Added in version 8.3.0.2 of package base.
