Unary logical NOT was already implemented earlier.
Logical AND OR are expressed via conditional expression:
* a && b -> a ? (b != 0) : 0
* a || b -> a ? 1 : (b != 0)
They work as expected in any expressions. For instance, having
`cond && f()`, f is called only if cond is true.
For primitive cases, like `a > 0 && b > 0`, Fift code is not optimal,
it could potentially be without IFs.
These are moments of future optimizations. For now, it's more than enough.
- split stdlib.tolk into multiple files (tolk-stdlib/ folder)
(the "core" common.tolk is auto-imported, the rest are
needed to be explicitly imported like "@stdlib/tvm-dicts.tolk")
- all functions were renamed to long and clear names
- new naming is camelCase
Lots of changes, actually. Most noticeable are:
- traditional //comments
- #include -> import
- a rule "import what you use"
- ~ found -> !found (for -1/0)
- null() -> null
- is_null?(v) -> v == null
- throw is a keyword
- catch with swapped arguments
- throw_if, throw_unless -> assert
- do until -> do while
- elseif -> else if
- drop ifnot, elseifnot
- drop rarely used operators
A testing framework also appears here. All tests existed earlier,
but due to significant syntax changes, their history is useless.
