Contracts now live directly on definitions via @ / =@ annotations and
travel automatically with exported values.
- Remove !export from lexer/parser/AST/evaluator/manifest/resolver and CLI.
- Simplify workspace module export logic: export all top-level local
definitions by default.
- Update Frontend.ContractDesugar:
- Named binder annotations (x@nat?) expand to per-argument withContract.
- Phantom annotations (@nat?) expand to a local raw helper plus a wrapper,
keeping fixed points shared and only depending on withContract.
- Merge lib/guardedBase.tri into lib/base.tri and annotate partial/sensitive
base functions: head, tail, last, add, sub, mul, div, mod, pow, min,
max, length, sum, product.
- Add check contract helper to lib/base.tri.
- Update demos/contractBasics.tri and README to reflect @/=@-only design.
- Update test suite: remove guardedBase import, replace explicit !export
test with a test verifying that contract annotations on an exported
definition are enforced on import.
- Fix remaining base.tri definitions (div/mod/pow) to stay point-free.
Perhaps the first webserver in Tree Calculus? Sure, it's married to a Haskell
IO runtime... but we're managing all of the actual webserver semantics in tricu!
This includes a demo Arboricx application server that is capable of storing
and serving bundles.
I'm deeply satisfied to be building an interaction tree runtime where
the interaction trees are themselves computed via and represented by
trees. It's trees all the way down.
Don't require/allow naming a module, instead require that the importer
names it. Allow importing into the local scope with the name !Local.
Simplify namespacing logic. Updates all tests to reflect these changes.
To encourage organizing code in a way that helps in understanding, I
have implemented the common idiom of requiring a `main` function. In
tricu and other functional languages, it is usually placed near the top
of the module. The evaluator gracefully handles the situation of passing
multiple files where the intermediary "library" files do not have main functions.
tricu now allows defining terms in any order and will resolve
dependencies to ensure that they're evaluated in the right order.
Undefined terms are detected and throw errors during dependency
ordering.
For now we can't define top-level mutually recursive terms.
Adds support for several special characters in identifiers. Adds a demo
for converting values to source code and another for checking equality.
Updates the existing demo and tests to reflect new names for functions
returning booleans.
