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. --- modules/webrtc/library_godot_webrtc.js | 100 +++-- modules/websocket/library_godot_websocket.js | 40 +- platform/javascript/SCsub | 23 +- platform/javascript/engine/engine.js | 271 ------------ platform/javascript/engine/externs.js | 3 - platform/javascript/engine/preloader.js | 135 ------ platform/javascript/engine/utils.js | 51 --- platform/javascript/js/engine/engine.externs.js | 3 + platform/javascript/js/engine/engine.js | 278 ++++++++++++ platform/javascript/js/engine/preloader.js | 129 ++++++ platform/javascript/js/engine/utils.js | 57 +++ 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 ++++++ platform/javascript/native/audio.worklet.js | 185 -------- platform/javascript/native/http_request.js | 144 ------- platform/javascript/native/library_godot_audio.js | 338 --------------- .../javascript/native/library_godot_display.js | 477 --------------------- .../native/library_godot_editor_tools.js | 56 --- platform/javascript/native/library_godot_eval.js | 85 ---- platform/javascript/native/library_godot_os.js | 311 -------------- 26 files changed, 2242 insertions(+), 2133 deletions(-) delete mode 100644 platform/javascript/engine/engine.js delete mode 100644 platform/javascript/engine/externs.js delete mode 100644 platform/javascript/engine/preloader.js delete mode 100644 platform/javascript/engine/utils.js create mode 100644 platform/javascript/js/engine/engine.externs.js create mode 100644 platform/javascript/js/engine/engine.js create mode 100644 platform/javascript/js/engine/preloader.js create mode 100644 platform/javascript/js/engine/utils.js 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 delete mode 100644 platform/javascript/native/audio.worklet.js delete mode 100644 platform/javascript/native/http_request.js delete mode 100644 platform/javascript/native/library_godot_audio.js delete mode 100644 platform/javascript/native/library_godot_display.js delete mode 100644 platform/javascript/native/library_godot_editor_tools.js delete mode 100644 platform/javascript/native/library_godot_eval.js delete mode 100644 platform/javascript/native/library_godot_os.js diff --git a/modules/webrtc/library_godot_webrtc.js b/modules/webrtc/library_godot_webrtc.js index d4c38f15a2..c8a10018e5 100644 --- a/modules/webrtc/library_godot_webrtc.js +++ b/modules/webrtc/library_godot_webrtc.js @@ -28,9 +28,9 @@ /* SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. */ /*************************************************************************/ -var GodotRTCDataChannel = { +const GodotRTCDataChannel = { // Our socket implementation that forwards events to C++. - $GodotRTCDataChannel__deps: ['$IDHandler', '$GodotOS'], + $GodotRTCDataChannel__deps: ['$IDHandler', '$GodotRuntime'], $GodotRTCDataChannel: { connect: function(p_id, p_on_open, p_on_message, p_on_error, p_on_close) { const ref = IDHandler.get(p_id);
