WUI: Web-based User Interface components for Ciao

Components for creating Web-based (HTML and JavaScript) user interfaces using Ciao active modules.

Used from ciao-serve command, predicates from active modules can answer HTTP requests for HTML documents or AJAX requests (for JavaScript interaction). We include a simple JavaScript driver for interaction with active modules.

Additionally this bundle contains support libraries for building menus, playgrounds, etc. required by other Ciao components.

Build

This code depends on some third-party tools and libraries. You can use this script to install them:

$ ciao custom_run . fetch_externals

Then you can build the bundle with:

$ ciao build
$ ciao custom_run . dist

TODO:

• Document and integrate better the generic JS framework for remote procedure calls (using active modules and a HTTP/CGI to JSON gateway program).

• Allow client-side Prolog processes using ciaowasm (bundle)

• FormData() is very limited on Safari. There is no simple workaroud, except creating a single form for upload and obtaining flag values without the form.

• This code contains a generic JS framework for creating user interfaces (based on library(menu), and external components like CodeMirror).
