Bridge Solver Online

This is a fork of the original Bridge Solver Online authored by John Goacher (https://mirgo2.co.uk/bridgesolver/)

Javascript

Code has been split into several files:

• Function definitions into functions.js
• Events into events.js
• Help text into helpText.js
• Inline javascript moved into the respective files
• Upgraded jQuery to jquery-4.0.0.min.js
• Main functionalities remain in ddummy6.js

Language

To allow text (help text and display text) to appear in other languages the following concept has been applied:

• A language switcher has been created (changeLanguage()). Whereever possible displayed text is piped through this function
• Added flags on the frontpage to allow the switch of language
• Currently English and German are implemented
• The default language is defined in ddummy6.js (e.g. language="en"). Language codes follow the 2-character code (e.g. en, de)

Styles

Inline Styles have been removed and added to the respective style sheet

HTML

HTML has been corrected to comply with W3C standards.

Functionality

Layout and buttons

The frontpage has been changed such that navigational buttons are visible at all times.

A URL parameter has been introduced to turn off the navigational buttons.

Loading of hands

Hands can be entered and analyzed in various ways:

• Choosing a local file by clicking the respective button on the frontpage
• Dropping a file onto the area on the frontpage covering the buttons
• Paste (CTRL-V on Windows/Linux, CMD-V on Mac) on the frontpage
• Using the respective button on the frontpage to retrieve data from the clipboard
• Manual input of single hands by using the respective button on the frontpage
• Loading a remote file via an URL parameter (e.g. ?file=https://example.com/tournament.pbn)). The remote server has to allow loading data via HTTP header Header set Access-Control-Allow-Origin * or specifically Header set Access-Control-Allow-Origin "https://thedomain.com".
• Board data can be provided completely with URL paramters
• For an overview of all available URL parameters see the file URL-Parameters.html

Supported file formats:

• .pbn
• .dlm
• .lin (BBO play and hand record files)

Handling of content in .pbn files

The [Result section of a .pbn file can optionally contain plain text enclosed in curly brackets. If present the text contained within is displayed at the bottom of the respective board in a highlighted box. The text may contain HTML markup for styling purposes.

Double Dummy Solver

Boards are analyzed using the double dummy solver authored by Bo Haglund / Sören Hein and implemented as a WebAssembly module. The analysis runs completely in the browser (no server component necessary).

The provided version is based on the DDS3 project (https://github.com/dds-bridge/dds) currently using the released version 3.1.

The sources for the WebAssembly module can be downloaded from here: https://github.com/krtschil/bsol-wasm/releases
