From 5651b2e586e9a9836ebe4f50f9223e237099cf86 Mon Sep 17 00:00:00 2001 From: Daniel Kolesa Date: Tue, 30 Jan 2018 17:03:37 +0100 Subject: [PATCH] eolian: deferred parsing of inherits + better static checks This change finally introduces deferred parsing of inherits to Eolian, after a long time and many iterations. That means instead of parsing inherits directly as part of the main file's parse pass, they're pushed into a queue and parsed later. The validation engine was modified to properly fill in the remaining info afterwards. This may introduce breakages but I haven't noticed any. It also properly unlocks cyclic dependency support in Eolian. Additionally, this also introduces checks for duplicates in class inherits (class Foo(Bar, Bar) is no longer possible) and it adds stricter name checks, so you can no longer have a class Foo.Bar and refer to it as Foo_Bar in implements. This was actually never meant to be supported, but the check was previously broken. @feature --- src/lib/elementary/efl_ui_legacy.eo | 2 +- src/lib/elementary/efl_ui_list.eo | 2 +- src/lib/elementary/elm_genlist.eo | 2 +- src/lib/eolian/database_validate.c | 72 ++++++++++++++++++++++++---- src/lib/eolian/eo_parser.c | 31 ++++++++---- src/lib/evas/canvas/efl_input_key.eo | 2 +- 6 files changed, 88 insertions(+), 23 deletions(-) diff --git a/src/lib/elementary/efl_ui_legacy.eo b/src/lib/elementary/efl_ui_legacy.eo index e077691310..301bcdc837 100644 --- a/src/lib/elementary/efl_ui_legacy.eo +++ b/src/lib/elementary/efl_ui_legacy.eo @@ -1,4 +1,4 @@ -interface EFl.Ui.Legacy (Efl.Interface) +interface Efl.Ui.Legacy (Efl.Interface) { [[The bg (background) widget is used for setting (solid) background decorations diff --git a/src/lib/elementary/efl_ui_list.eo b/src/lib/elementary/efl_ui_list.eo index 2ca88bdf74..64148ee5ff 100644 --- a/src/lib/elementary/efl_ui_list.eo +++ b/src/lib/elementary/efl_ui_list.eo @@ -99,7 +99,7 @@ class Efl.Ui.List (Efl.Ui.Layout, Efl.Ui.View, Efl.Ui.Scrollable.Interactive, Ef Efl.Layout.Signal.signal_callback_add;
