-# `ket`
+[***dizzle***](https://codeberg.org/unspeaker/tengri/src/branch/main/dsl)
+is a means of adding a tiny interpreted domain-specific language to your programs.
 
-**ket** is the configuration language of **tek**.
-it's based on [edn](https://en.wikipedia.org/wiki/Clojure#Extensible_Data_Notation)
-but without all the features.
+dizzle currently provides an s-expression based syntax.
 
-## usage
+dizzle parses source code by means of the `Dsl`, `DslExpr` and `DslWord` traits.
+those are implemented for basic stringy types and their `Option` and `Result` wrapped analogs.
+to customize parsing, define and use your own traits on top of the provided ones.
 
-### with `tengri_output`
+dizzle evaluates the parsed source code by means of the `DslNs` trait. the methods of
+this trait match literals, words, and expressions, against pre-defined lists. the
+`dsl_words` and `dsl_exprs` macros let you define those lists slightly less verbosely.

-## tokens
-
-ket has 4 "types", represented by variants of the `Value` enum:
-
-* `Num` - numeric literal
-* `Sym` - textual symbol
-* `Key` - textual key
-* `Exp` - parenthesized group of tokens
-
-### numeric literal
-
-numbers are passed through as is. only non-negative integers are supported.
-
-```edn
-0
-123456
-```
-
-### keys
-
-keys are the names of available operations. they look like this:
-
-```edn
-simple-key
-multi-part/key
-```
-
-keys are implemented by the underlying subsystem:
-
-* in `tengri_output`, keys are names of layout primitives
-* in `tengri_input`, keys are names of commands
-
-### symbols
-
-symbols that start with `:` represent the names of variables
-provided by the `Context` trait - such as command parameters,
-or entire layout components:
-
-```edn
-:symbol-name
-```
-
-symbols that start with `@` represent keybindings.
-they are parsed in `tengri_tui` and look like this:
-
-```edn
-@ctrl-alt-shift-space
-```
-
-### parenthesized groups
-
-parenthesized groups represent things like expressions
-or configuration statements, and look like this:
-
-```edn
-(some-key :symbol (some/other-key @another-symbol 123) 456)
