<?php
// This file contains support functions for display and editing
// preferences (global and project).
// Preferences are represented in two ways:
// - As a PHP structure (usually called $prefs)
// This has fields run_on_batteries, etc.
// The fields "project_specific" is plain XML
// - As XML (usually called $prefs_xml)
//
// This XML has the general structure
// <global_preferences>
// <mod_time>...</mod_time>
// <run_if_user_active/>
// <work_buf_min_days>1.3</work_buf_min_days>
// ...
// <venue name="home">
// <run_if_user_active/>
// ...
// </venue>
// </global_preferences>
//
// and
//
// <project_preferences>
// <resource_share>4</resource_share>
// <project-specific>
// ... (arbitrary project-specific XML)
// </project-specific>
// <home>
// ...
// </home>
// </project_preferences>
//
// In addition there are some fields of the user table
// (send_email and show_hosts) that are treated as project preferences
// Various functions are defined below for converting between these forms,
// and also to/from HTML form elements
include_once("../project/project_specific_prefs.inc");
// strings describing various preference fields
