Because of Eina_Value being less than optimal in our usage, we're dropping it in Eolian.
This simplifies the code and makes it easier to bind to other languages, which
will aid new generators. Also, we're dropping long double support from eo files
and expressions as it causes an ABI breakage in gcc 4.4.
This change adds a new API to retrieve the legacy prefix for enum members
and also adds support for generating enums into the C generator. Besides that,
it prevents generation of entire struct contents when the .eo file declares
a named struct inside of a typedef - as the struct itself gets generated later on.
I don't know what I was thinking, struct and enum fields need to be ordered
so now we keep a separate list around containing the field names in correct order.
This implements the previously declared APIs to manipulate enum types. Also,
it implements the appropriate lookups in expression evaluation so that you
can refer to constants and enums inside constant expressions.
Also added API to retrieve value of a variable (forgot about that one)
and made it impossible to create extern constants (doesn't make sense)
as well as made it impossible to give extern globals values.
Nothing parses yet, and no API is exposed. Also, move the remaining instances of file
inside of existing structures to Eolian_Object and parse basename only once.
This way we can only lex expr related tokens (operators etc.) when actually
about to parse an expression. That allows stuff like nested complex types
without the lexer treating the endings as right shift.
so instead of "unsigned int" you get "uint". This is important for handling of
expressions and cross-language interoperability. You can use c_type_get on the
base type to get the C name. Also, append the appropriate suffix to number literals
when calling eolian_expression_value_to_literal.
This commit also does several side (related) changes. Particularly, it updates
the Eolian C generator to use the new API, it adds missing expr types (null, char)
and masks, updates the API dealing with default return values to use expressions
instead of strings and does several fixes (mainly in lexer) around the place.
It also disallows single quoted strings as those are reserved for characters.
