From a82f70ea9f98ed0a602a20f7fe8954f6e4200b25 Mon Sep 17 00:00:00 2001 From: Fabio Alessandrelli Date: Thu, 19 Nov 2020 16:54:07 +0100 Subject: [HTML5] Libraries refactor for linting. Initial work to make liniting easier. This includes: - Rename http_request.js to library_godot_http_request.js. - Rename externs.js to engine.externs.js. - New library_godot_runtime.js (GodotRuntime) wraps around emscripten functions. - Refactor of XMLHttpRequest handler in engine/preloader.js. - Few fixes to bugs spotted by early stage linting. --- platform/javascript/js/libs/audio.worklet.js | 186 ++++++++ platform/javascript/js/libs/library_godot_audio.js | 340 +++++++++++++++ .../javascript/js/libs/library_godot_display.js | 477 +++++++++++++++++++++ .../js/libs/library_godot_editor_tools.js | 56 +++ platform/javascript/js/libs/library_godot_eval.js | 87 ++++ .../js/libs/library_godot_http_request.js | 143 ++++++ platform/javascript/js/libs/library_godot_os.js | 280 ++++++++++++ .../javascript/js/libs/library_godot_runtime.js | 120 ++++++ 8 files changed, 1689 insertions(+) create mode 100644 platform/javascript/js/libs/audio.worklet.js create mode 100644 platform/javascript/js/libs/library_godot_audio.js create mode 100644 platform/javascript/js/libs/library_godot_display.js create mode 100644 platform/javascript/js/libs/library_godot_editor_tools.js create mode 100644 platform/javascript/js/libs/library_godot_eval.js create mode 100644 platform/javascript/js/libs/library_godot_http_request.js create mode 100644 platform/javascript/js/libs/library_godot_os.js create mode 100644 platform/javascript/js/libs/library_godot_runtime.js (limited to 'platform/javascript/js/libs') diff --git a/platform/javascript/js/libs/audio.worklet.js b/platform/javascript/js/libs/audio.worklet.js new file mode 100644 index 0000000000..a27035ef22 --- /dev/null +++ b/platform/javascript/js/libs/audio.worklet.js @@ -0,0 +1,186 @@ +/*************************************************************************/ +/* audio.worklet.js */ +/*************************************************************************/ +/* This file is part of: */ +/* GODOT ENGINE */ +/* https://godotengine.org */ +/*************************************************************************/ +/* Copyright (c) 2007-2020 Juan Linietsky, Ariel Manzur. */ +/* Copyright (c) 2014-2020 Godot Engine contributors (cf.
