This is set to 1 second by default. Usually if it hasn't found a result
by then, it never will, but given that we find the first batch of
results then sort them, the timeout also stops us fruitlessly searching
for more solutions.
Hopefully 1s is more than enough for CI too. There is a mechanism to
change the timeout (%search_timeout) so if it turns out that CI needs
longer in some cases, we can increase it there.
I haven't documented this yet, but proof/definition search needs
documenting in general. I'll get to that.
The timer mechanism may also be useful elsewhere - I'm considering it
for ambiguity warnings, because the ambiguity depth limit isn't working
very well for that.
We already did this, but missed a few cases due to the way arguments are
elaborated. So now, when checking an LHS, we don't allow LHS argument
types to be inferred from the pattern, but rather they must be inferred
from elsewhere. To do this, we keep track of the constraints which would
be solved when inferring the type, and make sure they don't solve any
new metavariables. Fixes#1510, and also now gets the error location
right as a bonus!
We need to fully evaluate, not just the public export names, otherwise
we don't pattern match properly and potentially generate catch all
patterns we don't mean.
Fixes#1537
* Add utility functions to treat All as a heterogeneous container
* Distinguish RefC Int and Bits types
* Change RefC Integers to be arbitrary precision
* Add RefC Bits maths operations
* Make RefC div and mod Euclidean
* Add RefC bit-ops tests
* Add RefC integer comparison tests
* Add RefC IntN support
This saves a lot of unnecessary exploring of size change graphs, which
can get over the top quite quickly if there's complex mutual
definitions, or even just a single function with an interesting variety
of recursive calls.
Fixes#1365Fixes#1277Fixes#645
- Fix off-by-one error in String reverse
- Correct order of arguments in strSubstr
- Actually use start index of strSubstr
- Reduce memory usage of strSubstr in case of overrunning string end
- Add fastPack/fastUnpack/fastConcat
- Use unsigned chars for character comparisons
- Fix generated C character encodings
We do this during desugaring because elaboration may insert valid
`?` values on the LHS (e.g. when elaborating things that cannot be
pattern-matched on and should be checked to be forced).
* Banners for test pools
* Summary with the list of failing tests at the end
* Option to write the list of failing tests to a file
* Option to read the list of tests to run from a file
* Using these two latest features to add a new make target to rerun precisely the tests that failed last time
This adds new `Int8`, `Int16`, `Int32` and `Int64` data types
to the compiler, thus working towards properly specified integer
types as discussed in #1048.
In addition, the following changes / corrections are made:
* Support casts from `Char`, `String`, and `Double` to all integer
types (and back). This fixes#1270.
* Make sure that all casts to limited-precision integers are properly
bounds checked (this was not the case so far for casts from `String`
and `Double` to `Int`)
* Add a thorough set of tests to make sure all bounds checks work
correctly for all supported casts and arithmetic operations
Previously, parameter block reused the same syntax as in Idris1:
```
parameters (v1 : t1, … , vn : tn)
```
Unfortunately this syntax presents some issues:
- It does not allow to declare implicit parameters
- It does not allow to specify which multiplicity to use
- It is inconsistent with the syntax used for named arguments elsewhere
in the language.
This change fixes those three problems by borrowing the syntax for
declaring type parameters in records:
```
parameters (v1 : t2) (v2 : t2) … (vn : tn)
```
It also enables other features like multiple declarations of arguments
with the same type:
```
parameters (v1, v2 : Type)
```
