The `WebExtensions -`_ API enables the development of -cross-browser extensions. Google Chrome / Chromium, Mozilla Firefox, Opera and -Microsoft Edge will all offer support for WebExtensions and thus be able to support Taler. - -Currently Chrome hast the best support for WebExtensions (since the API is a -superset of Chrome's extension API). - ------------------------ -Development Environment ------------------------ - -The *wxwallet* mainly written in the `TypeScript -`_ language, which is a statically typed -superset of JavaScript. - -While the *wxwallet* is mainly intended to be run from inside a browser, the -logic is implemented in browser-independent modules that can also be called -from other environments such as `nodejs `_. This is -especially useful for automatically running unit tests. - - ------------------ -Project Structure ------------------ - -.. parsed-literal:: - - **manifest.json** extension configuration - **package.json** node.js package configuration - **tsconfig.json** TypeScript compiler configuration - **gulpfile.js** Build tasks script - **lib/** - **vendor/** 3rd party libraries - **wallet/** actual application logic - **emscripten/** emscripten object file and glue - **test/** - **run_tests.js** nodejs entry point for tests - **tests/** test cases - **content_scripts/notify.ts** wallet<->website signaling - **backgrond/main.ts** backend entry point - **img/** static image resources - **style/** CSS stylesheets - **pages/** pages shown in browser tabs - **popup/** pages shown the extension popup - - -------------------- -Building the Wallet -------------------- - -To build the extension for use during development, simply run the TypeScript compiler -from the extension directory: - -.. code-block:: sh - - $ cd wallet.git/wallet_webextension/extension/ - $ tsc - -This will use the ``tsconfig.json`` with development options such as `source map`_ support. - -.. _`source map`: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit - -When TypeScript source files are added or deleted to the project, make sure that the -globs in ``gulpfile.js`` match them so that they will be compiled. The ``tsconfig.json`` -is generated by running: - - -.. code-block:: sh - - $ gulp tsconfig - -.. caution:: - - Do not edit the ``tsconfig.json`` manually. The source files should be defined in - one place, and that is ``gulpfile.js``. - -To pack the extension in a format that can be uploaded to the Google Webstore, run: - -.. code-block:: sh - - $ gulp package - -This will build the wallet without source maps, copy resource files (which also need to be -specified in ``gulpfile.js``) and create an archive. - - ----------- -Emscripten ----------- - -`Emscripten `_ is C/C++ -to JavaScript compiler. Emscripten is used in the *wxwallet* to access -low-level cryptography from *libgcrypt*, and miscellaneous functionality from -*libgnunetutil* and *libtalerwallet*. - -TODO: say things about wrappers - - --------------------------------------- -Target Environments and Modularization --------------------------------------- - -Modules in the wallet are declared in TypeScript with -the ES6 module syntax. These modules are then compiled -to `SystemJS `_ `register` modules. - -SystemJS modules can be loaded from the browser as well as from nodejs. -However they require special entry points that configure the module system, -load modules and execute code. Examples are `backgrond/main.ts` for the -browser and `test/run_tests.js` for nodejs. - -Note that special care has to be taken when loading the Emscript code, -as it is not compatible with the SystemJS module, even in the `globals` -compatibility mode. - -The TypeScript sources in the *wxwallet* are compiled down to ES5, both to -enable running in node.js without transpilers and to avoid a `bug -`_ in the TypeScript -compiler. - ----------------------------- -IndexedDB Query Abstractions ----------------------------- - -The *wxwallet* uses a fluent-style API for queries on IndexedDB. - -TODO: say more about this - - -------- -Testing -------- - -Test cases for the wallet are written in TypeScript and -run with `mochajs `_ and the `better-assert `_ assertion -library. - -Run the default test suite with ``npm run test``, which will -call `mocha` with the right parameters. - - --------------------- -Internationalisation --------------------- - -Strings in the JavaScript code are internationalised using the following functions: - -- *i18n*: translate string with arbitrary arguments, the result is returned as string. - -.. code-block:: js - - i18n`You have ${n} coins.` - -- *i18n.parts*: Interpolate i18nized values with arbitrary objects. - Useful for example to include HTML elements. - -.. code-block:: js - - i18n.parts`Visit ${link} to get more coins.` - -- *i18n.pluralize*: translate with plural form. - The i18n.number() function returns a ``PluralNumber`` object - that specifies the argument that determines the plural form, - if not present the first numeric argument is used. - -.. code-block:: js - - i18n.pluralize( - i18n`${i}: you have ${i18n.number(n)} coin.`, - `${i}: you have ${i18n.number(n)} coins.`); - -These functions are defined in ``lib/i18n.ts``. -Include ``lib/vendor/jed.js``, ``lib/i18n.js``, ``lib/i18n-strings.js`` to use them. - -To extract strings from sources and update the .po files, run: - -.. code-block:: sh - - $ make i18n - -In static HTML files the ``lang`` attribute is used for language-specific strings: - -.. code-block:: html - -
