As it is no longer necessary to pass unit when evaluating exprs,
it is not necessary to pass it here either. Convert all the APIs
to the new style and update all instances in our tree.
Units now form an actual tree stored in their own hash. This will
later replace all global state of Eolian, by introducing a master
unit that you will pass around.
This disallows deeply nested pointers, you can only explicitly
ptr() on types that are strictly value types.
For a few cases where it was necessary to override this behavior,
you can use legacy(ptr(x)) as a temporary measure.
Most of the time you need to retrieve the class from the string
anyway, so remove this relic of old Eolian and gain some small
performance benefits and extra convenience.
Subtly breaks API but everything should be updated.
These types are of questionable value and the API was not entirely
thought out - remove for now, and if a legitimate use is found
later, they may be readded (with a better API), but typically it
seems best to redesign the bad APIs around safe containers...
Even though ownership info belongs to params/returns/etc at syntax
level, we can still store it in the type and turn several API funcs
into one this way.
This is the new ownership system for Eolian, working on params,
returns, struct fields or events directly rather than specifying
ownership at type level. As the new system will evolve it will
gain missing features and necessary checks.
First steps toward explicit function pointer support in eolian.
To declare a function pointer type, use the following syntax, similar to
a regular eolian method declaration.
function FunctionName {
params {
...
}
return: Return type
}
Units are Eolian files (eo/eot). Each unit contains information
about its class, dependencies, variables and types. This allows
for saner checking to be done.
