The parse time -vs- run time duality
Wednesday, December 27, 2006
In Factor, anything which can be done via syntax in a source file can also be done at runtime. This lets you construct code on the fly, and define new words with the new code, just as if they were written in a source file:
| Task | Parsing word | Ordinary word |
|---|---|---|
| Defining a word | : | define-compound |
| Defining a symbol | SYMBOL: | define-symbol |
| Defining a generic word | GENERIC: | define-generic |
| Defining a generic word | G: | define-generic* |
| Defining a method | M: | define-method |
| Defining a tuple class | TUPLE: | define-tuple |
