I’m just getting this project set up, so docs and code are buggy and missing until I update this document.
TiREPL provides the facility for interactive editing of running titanium mobile applications (sometimes called “Live Coding”). This is done using Read Eval Print Loop (REPL) on the running application connected to a client over a network transport layer. Following is a short description of the main components.
- /q or /quit Kill the current session and disconnect
- /session_id Get the unique session_id for this active session
- /message <base64 encoded JSON message object> Encoded message object sent by the client
- /message_response <base64 encoded JSON message object> Encoded message reply sent back to the client by the REPL server
Message objects are just JSON dictionaries. The format is as follows:
- Client request messages have the following keys/values:
- “session-id” - Id of session this message belongs to.
- “id” Id of this message. Incremental id unique to this session.
- “type” Message type of this message. Currently there is only eval_src
- Server response message have the following keys/values:
- “session-id” Id of session this message belongs to.
- “id” Id of the message being replied to.
- “type” Message type of this message. Currently there is only eval_response
- “status” status code for this evaluation, either ok or error
- “result” resulting object or exception object of the remote evaluation
Clients can simply be a telnet session connected directly to the raw socket, or a client can provide more features such as input history, error reporting etc using the JSON encoded messaging interface. There is an emacs client interface provided with this project that uses the messaging interface.
To install these modules, you will need a fully working and recent Titanium Developer installed, as well as a working Xcode and Android developer setup.
- For building for iPhone: replserver_iphone/ReplServer/titanium.xconfig Make sure the file paths and titanium_mobile sdk match your system
- For building for Android: replserver_android/build.xml Make sure the required file paths match your system
cd replserver_iphone/ReplServer python ./build.py
You should now have a file: com.evocomputing.replserver-iphone-0.1.zip
Now, copy this file to your Titanium directory: shell:
cp com.evocomputing.replserver-iphone-0.1.zip "/Library/Application Support/Titanium/"
Titanium should pick this up and install it in the correct directory.
cd replserver_android/ ant deploy
This will build the titanium-repl.jar, and install it with the other jars in the mobile sdk
- Android Open local proxy port for emulator using adb command shell shell:
/opt/android-sdk/tools/adb forward tcp:5051 tcp:5051
See the app.js file in the examples/ReplTest example project for how to integrate the module in your titanium application.
