Have added lot of new features, witch have been possible to write in C but with lot of lines of code. I love Vala because allows me to be more productive, even Genie allows more simplification on Vala's syntax.
I think that former syntax are more productive and easy to read than the last. Could allow to work with-in Vala's code with lot of data from a DataBase or any other data source. GdaData objects and interfaces allows to access that data using just GObjects and Vala code, abstracting most of internal operations and mapping to properties and methods, and allow to use Gee collections to make more easy to access to data using by code; but could reach a next level by adding some syntax support on Vala for SQL like queries. I know that adding syntax support may is not easy or is far from Vala principles. Then I would like to see a way to allows Vala compiler with a mechanism of PLUG-INS for syntax support. Then GdaData could add its own plug-in for SQL syntax when it is installed. The above allows not to distract Vala from its principles, but allows to others add syntax for specific task that makes more easy/productive and clear way to do the same. Less code and clear syntax, allows more productive less errors. > That said, implement filter, map and fold in your collections library and > you can avoid the LINQ syntax :-) > Consider libgee has filter, map, fold and scan with which you can > implement a large subset of LINQ, including aggregate operators. > _______________________________________________ > vala-list mailing list > vala-list@gnome.org > https://mail.gnome.org/mailman/listinfo/vala-list > -- Trabajar, la mejor arma para tu superación "de grano en grano, se hace la arena" (R) (en trámite, pero para los cuates: LIBRE) _______________________________________________ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
