- Add support to the formatter for these doc comments
- Add a new field to `Arg` `doc: Option<String>`
- Don't attach docs immediately after typechecking a module
- instead we should do it on demand in docs, build, and lsp
- the check command doesn't need to have any docs attached
- doing it more lazily defers the computation until later making
typechecking feedback a bit faster
- Add support for function arg and validator param docs in
`attach_module_docs` methods
- Update some snapshots
- Add put_doc to Arg
closes#685
This improves error messages for `a |> b(x)`.
We need to do a special check when looping over the args
and unifying. This information is within a function that does not belong
to pipe typer so I used a closure to forward along a way to add
metadata to the error when the first argument in the loop has a
unification error. Simply adding the metadata at the pipe typer
level is not good enough because then we may annotate regular
unification errors from the args.
Now we "handle" vars that call the cyclic function.
That includes vars in the cyclic function as well as in other functions
"handle" meaning we modify the var to be a call that takes in more arguments.
Bumped into this randomly. We do correctly parse escape sequence, but
the format would simply but the unescaped string back on save. Now it
properly re-escapes strings before flushing them back. I also removed
the escape sequence for 'backspace' and 'new page' form feed as I
don't see any use case for those in an Aiken program really...
fix: Opaque types are now properly handled in code gen (i.e. code gen functions, in datums/redeemers, in from data casts)
chore: add specific nested opaque type tests to code gen
I originally didn't add this because I thought this was mutually
recursive functions, which I couldn't picture how that would work;
I refactored all this logic into modify_self_calls, which maybe needs a
better name now.
Perf gain on some stdlib tests (line concat tests) is 93%!!
We also flip the recursive_statics fields to recursive_nonstatics; This makes the codegen a little easier. It also has a hacky way to hard code in some recursive statics for testing
Any methods to a recursive function that are unchanged and forwarded
don't need to be applied each time we recurse; instead, you can
define a containing lambda, reducing the number of applications
dramatically when recursing
feat: finish expect type on data constr
fix: tuple clause was exposing all items regardless of discard
fix: tuple clause was not receiving complex_clause flag
fix: condition for assert where constructor had 0 args was tripping assert
fix: had to rearrange var and discard assignment to ensure correct val is returned
fix: binop had the wrong type
When rendering missing or redundant patterns, linked-list would
wrongly suggest the last nil constructor as a pattern on non-empty
list.
For example, before this commit, the exhaustivness checker would yield:
```
[(_, True), []]
```
as a suggestion, for being the result of being a list pattern with a
single argument being `(_, True) :: Nil`. Blindly following the
compiler suggestion here would cause a type unification error (since
`[]` doesn't unify with a 2-tuple).
Indeed, we mustn't render the Nil constructor when rendering non-empty
lists! So the correct suggestion should be:
```
[(_, True)]
```
This was trickier than expected as the expression parser, and in particular the bin-op parser will interpret negative patterns as a continuation of a binary operation and eventually choke on the next right-arrow symbol. This is due to how we actually completely erase newlines once we're done with the lexer. The newline separating when clause is actually semantically important. In principle, we could only parse an expression until the next newline.
Ideally, we would keep that newline in the list of token but it's difficult to figure out which newline to keep between two right arrows since a clause guard can be written over multiple lines. Though, since we know that this is only truly a problem for negative integers, we can use the same trick as for tuples and define a new 'NewLineMinus' token. That token CANNOT be part of a binop expression. That means it's impossible to write a binary operation with a minus over multiple lines, or more specifically, with the '-' symbol on a newline. This sounds like a fair limitation. What we get in exchange is less ambiguity when parsing patterns following expressions in when clause cases.
Another more cumbersome option could be to preserve the first newline encountered after a 'right-arrow' symbol and before any parenthesis or curly brace is found (which would otherwise signal the beginning of a new block). That requires to traverse, at least partially, the list of tokens twice. This feels unnecessary for now and until we do face a similar issue with a binary operator.
The main goal is to make the parser more reusable to be used for when-clauses, instead of the expression parser. A side goal has been to make it more readable by moving the construction of some untyped expression as method on UntypedExpr. Doing so, I got rid of the extra temporary 'ParseArg' type and re-used the generic 'CallArg' instead by simply using an Option<UntypedExpr> as value to get the same semantic as 'ParseArg' (which would distinguish between plain call args and holes). Now the chained parser is in a bit more reusable state.
We do not actually every parse negative values in there, as a negative value is a combination of a 'Negate' and 'UInt' expression.
However, for patterns and constant, it'll be simpler to parse whole Int values as there's no ambiguity with arithmetic operations
there. To avoid confusion of having some 'Int' constructors containing only non-negative values, and some being on the whole range,
I've renamed the constructor to 'UInt' to make this more obvious.
This was a bit more tricky than anticipated but played out nicely in
the end. Now we have one holistic way of parsing todos and errors
instead of it being duplicated between when/clause and sequence. The
error/todo parser has been moved up to the expression part rather than
being managed when parsing sequences. Not sure what motivated that to
begin with.
Fixes#621.
Alleviate a bit more the top-level expression parser. Note that we
probably need a bit more disciplined in what we export and at what level
because there doesn't seem to be much logic as for whether a parser is
private, exported to the crate only or to the wide open. I'd be in favor
of exporting everything by default.
Also moved the logic for 'int' and 'string' there though it is trivial. Yet, for bytearray, it tidies things nicely by removing them from the 'utils' module.
Equality on a union-type is potentially dangerous as the compiler won't
complain if we add a new case that we don't cover. Reversing the
assignment by yielding a `Token` for a given `AssignmentKind`. This way
we can use a pattern-match that got us covered for future cases.
The 'public' util was arguably not really adding much except a layer of indirection.
In the end, one useful parsing behavior to abstract is the idea of 'optional flag' that we use for both 'pub' and 'opaque' keywords.
