Cwtch - UI

This codebase provides a graphical user interface for Desktop and Android for Cwtch: Privacy Preserving Infrastructure for Asynchronous, Decentralized and Metadata Resistant Applications

Security

Cwtch is an experimental concept and prototype. We do not recommend you use Cwtch today if you require secure communication. At least, not yet.

If you discover a security issue, please log an issue above, or email team@cwtch.im.

Compiling & Running

This code relies on therecipe/qt before getting started consult the Installation and Getting Started documentation to get that up and running. It will make building this much easier.

Desktop

qtdeploy build desktop
./deploy/linux/ui.sh -local -debug 2>&1 | grep -v 'Detected anchors on an item that is managed by a layout.'

The -local and -debug flags are helpful when developing.

Android

We supply an arm-pie version of tor in android/libs/armeabi-v7a with the name libtor.so

qtdeploy -docker build android
adb install deploy/android/build-debug.apk

Windows

• Download and install QT Open Source edition
• Go to My Computer - Right Click on This PC - Advanced System Settings - Environment Variables
  • New - QT_DIR = C:\Qt (or wherever you have it installed)
  • New - QT_VERSION = 5.12.1 (because I picked 5.12.1)
  • Edit the Path Variable and Add C:\Qt\Tools\mingw530_32\bin
• Install MSYS2 (Bash shell for windows)
• Install Go and make sure it's in the PATH, and add your GOPATH/bin to the PATH
• Setup therecipe/qt (instructions https://github.com/therecipe/qt/wiki/Installation-on-Windows)
  • go get -u -v github.com/therecipe/qt/cmd/...
  • qtsetup (Can take around an hour?)

If all that is done, then check out cwtch.im/ui and run qtdeploy in the root of it.

Currently you will need to manually run tor first before running cwtch.im/ui. Use the included tor and torrc file: tor -f torrc

Development

Translations

(If you'd like to add a new translation, feel free to open an issue and we can generate the .ts file for you to edit by hand, or in QT Linguist!)

Add new translation

0. Install the language tools if you have not already (on linux: sudo apt-get install qttools5-dev qttools-dev-tools)

1. Edit ui.pro and add a new line in the variable definition for TRANSLATIONS like:

   TRANSLATIONS = i18n/translation_en.ts
   i18n/translation_de.ts

2. Edit qml.qrc and add a new line near the other translation files like:

   <file>i18n/translation_de.qm</file>

3. To update and generate your new translation file, run lupdate ui.pro and you will find your new file in the i18n/ directory.

Updating translations

Run lupdate ui.pro to update all the translation files in the i18n/ directory, then edit your languages' .ts file to make the appropriate changes. It is recommended to use QT Linguist (linguist) to edit the files.

When done, run lrelease ui.pro to compile all the translations from their .ts files into .qm files for use in the program. Then you can compile the ui program.
