v1.1.0 - 2024-09-03

Added

aiken-lang: fix zero-arg builtins mk_nil_data and mk_nil_pair_data invokation. @KtorZ
aiken-lang: rename some builtins. @KtorZ

old name new name

mk_nil_data new_list

mk_pair_data new_pair

mk_nil_pair_data new_pairs
aiken-lang: duplicate import lines are now automatically merged instead of raising a warning. However, imports can no longer appear anywhere in the file and must come as the first definitions. @KtorZ
aiken-lang: remove warning on discarded expect, allowing to keep 'side-effects' when necessary. See #967. @KtorZ
aiken-lang: allow expect as last (or only) expression in function body, when clauses and if branches. Such expressions unify with Void. See #1000. @KtorZ
aiken-lang: allow tests to return Void. Tests that return Void are treated the same as tests that return True. See #1000. @KtorZ
aiken-lang: rework traces to be (1) variadic, (2) generic in its arguments and (3) structured. @KtorZ

In more details:
1. Enables the trace keyword to take one, two or any argument really separated by comma after the first. For example:
```
trace @"a classic trace"

// ..

trace @"condition_1": @"foo"

// ...

trace @"condition_2": @"foo", @"bar"
```
2. Enables the trace keyword to not only take strings as arguments; but any data-type that is serialisable (i.e. that can be cast to Data). It is fundamentally identical to calling the cbor.diagnostic function from the standard lib; except that this is done and glued with the rest of the trace automatically.
```
trace @"condition_1": [1, 2, 3]

// ...

let my_var = Some("foo")
trace my_var
```
3. Changes the behavior of the --trace-level compact mode to now:
- remove trace-if-false (? operator) traces entirely in this mode;
- only keep the label (first trace argument) and error when it isn't a string.
See also #978.
aiken-lang: rework formatter behaviour on long-lines, especially in the presence of binary operators. @KtorZ
aiken-lang: provide better errors for unknown types used in cyclic type definitions. @KtorZ
aiken-project: fix blueprint's apply truncating last character of outputs. See #987. @KtorZ
aiken-project: provide better error (include input ref) when inputs are missing during transaction evaluation. See #974. @KtorZ
aiken-project: module inhabitants are no longer alphabetically sorted when generating documentation. Instead, the order in which they are defined in the module is used. @KtorZ
aiken-project: the sidebar links to modules within a package is now fully hierarchical and (hopefully) better-looking. @KtorZ

Removed

aiken-lang: clause guards are no longer part of the language. See #886. @KtorZ.

v1.0.29-alpha - 2024-06-06

Added

aiken-lang: new LSP quickfix for 'use let' warning. @KtorZ

Changed

aiken-lang: the keyword fail on property-based test semantic has changed and now consider a test to succeed only if every execution of the test failed (instead of just one). The previous behavior can be recovered by adding the keyword once after fail. @KtorZ

Fixed

aiken-lang: fixed the number of 'after x tests' number reported on property test failure, which was off by one. @KtorZ
aiken-lang: fixed parsing of single hex digits. @KtorZ

aiken-lang: fix for generic constrs being used as functions causing type mismatch errors. @Microproofs
aiken-lang: fix for error occuring when a field holds Data that is not a constr type when compiler traces are on. @Microproofs

Changed

Warning

BREAKING-CHANGE

2-tuples (a, b) are now treated the same as 3+ tuples -- which directly impacts the way that Aiken now deserialise those, especially when nested inside a List.

To deserialize into a list of 2-tuple (List<(a, b)>), one is now expected to provide a CBOR array of arrays (of 2 elements). Previously, this would require to provide a CBOR map! The downside of the latter is that CBOR serialization libraries do not necessarily preserve the order of keys in a map which could cause issues down the line, in particular with Aiken's dictionnaries.

To recover the old behavior when desired, Aiken introduces a new type Pair<a, b> to the language. So any existing program can be migrated by switching any occurences of (a, b) to Pair<a, b>.

However, it is often preferable to use 2-tuples where possible. The main place you will see usage of Pair is in the script context because its form is imposed by the ledger.

aiken-lang: altered internal representation of 2-tuples to distinguish them from pairs. @KtorZ @Microproofs
aiken-lang: some more code gen cleanup. @Microproofs
aiken-lang: new optimization for wrapped builtins found in the stdlib. @Microproofs
aiken-project: slightly restyle warnings to be less noisy. @KtorZ

Added
