The data in the report includes necessary information for starting
the compiler service and setting up the project paths in the IDE.
the default verbosity of 1 is now set in the compiler code to fix an
issue with verbosity being temporary set to 1 during config parsing
even when it's explicitly overridden on the command-line.
compiler/lexbase was temporary renamed to nimlexbase as a
work-around for a codegen naming conflict with lib/pure/lexbase
resulting in linking errors (further investigation needed).
Lines from the original source are outputted as comments next to line directives.
Hopefully, this will make debugging codegen problems easier.
Other changes:
The frame setup code now uses a single-line C macro. My motivation was to reduce
the noise in the generated output and make it easier to step over the boiler-plate
code, but counter-intuitively this also improved the overall compilation speed a
little bit so I applied the same treatment to line tracking too (this reduces the size of
the generated files and the explanation is that probably the I/O overhead dominates
the macro expansion costs).
See the section `do notation` in the manual for more info.
* nkMacroStmt has been removed
Macro statements are now mapped to regular nkCall nodes.
The support for additional clauses (such as else, except, of, etc)
have been restored - they will now appear as additional arguments
for the nkCall node (as nkElse, nkExcept, etc nodes)
* fixed some regressions in the `is` operator and semCompiles
types are now valid proc/template/macro params and you can overload over them:
proc foo(T: typedesc) # accept any type
proc foo(T: typedesc{int}) # overload specifically for int
proc foo(T: typedesc{int or float or Callable}) # overload for any type matching the constraints
expr{type} is a param expecting compile time value of the designated type (or type class).
when typedesc or expr params are used with a proc, the proc will be instantiated once
for each unique type/value used as parameter.
