A web client for Projector.

Contents:

Running

The latest commit from master is built and deployed on our site. More info

The latest version can be downloaded at the Artifacts page.

Building

The client needs only static files. The following script will build the client files in the projector-client-web/build/distributions dir:

./gradlew :projector-client-web:browserProductionWebpack

After building, you can run the HTML page: projector-client-web/build/distributions/index.html.

Notes

Tested browsers:

  • Chromium.
  • Firefox.

Page parameters

You can set some settings in query parameters like this: index.html?host=localhost&port=8887&wss. Actual list of parameters can be found in the ParamsProvider.kt file. Here we describe them.

Main parameters

Name Type Default value Description
host String Host of the web page Set the host of projector-server to connect.
port String Port of the web page Set the port of projector-server to connect.
path String Path of the web page Set the path of projector-server to connect.
wss Presence Protocol of the web page Enable security of WebSocket connection.
notSecureWarning Boolean true Enable warning saying that the context is not secure.
token String? Not present Set a password which will be checked by the server on the connection.
inputMethod String? ime ime supports Input Method Editors and Dead Keys. mobileOnlyButtons – enable overlay controls handy for mobile devices. mobile – enable overlay controls and a virtual keyboard toggle handy for mobile devices. legacy doesn't support input methods.
ideWindow Int? Not present Specify the IDE window ID to show. The first ID is 0. If not presented, all IDE windows are shown.
layout Enum (String) jsDefault Specify keyboard layout. Possible values: jsDefault, frAzerty.

Debug/test parameters

Name Type Default value Description
clipping Presence Not present Show borders of clipping areas via red and blue lines.
logUnsupportedEvents Presence Not present Log unsupported events received from server to browser console.
doubleBuffering Boolean true Enable double buffering for rendering to on-screen surfaces.
enableCompression Presence Not present Use compression for sending and receiving WebSocket messages.
toClientFormat String jsonManual Sets format of data from server to client: json, jsonManual, protoBuf.
imageTtl Double 60_000.0 Set caching time of unused images in ms.
flushDelay Int? 1 Set buffering time of events from client in ms. If the value is not integer, unbuffered mode is used: every client event is sent to the server immediately.
showTextWidth Presence Not present Show near-text lines of browser width and desired width.
showSentReceived Presence Not present Show blinking indicators in the corner of the screen when events were sent or received.
showPing Presence Not present Show some info of simple ping to and from server.
pingAverageCount Int? Not present Activate displaying average ping of this number of iterations.
backgroundColor String #282 (green) Set color of area where there are no windows.
userScalingRatio Double 1.0 Set scaling ratio.
pingInterval Int 1000 Set interval of pinging in ms.
showProcessingTime Presence Not present Log processing time of server messages to browser console.
repaintArea Presence Not present Enable ability to see repainted areas, use a shortcut to toggle (more info below).
speculativeTyping Presence Not present Enable rendering symbols in Editor not waiting for draw events from server.
repaintInterval Int 333 Set interval of repainting that is needed to paint loaded images in ms.
cacheSize Int 5M Set size of cache for images in Chars.
blockClosing Boolean true Enable blocking of accidental closing of the web page
relayServerId String? Not present Identifier of Projector server to connect to for relay connection. Warning: Static files must be accessed via https when relay is used.
speculativeTypingLatency Int 0 Sets latency before key press event is sent to server if speculative symbol for the event was drawn.
