<?php /* File: $Id$ This script generates an XSLT include file that contains templates specifying the date ranges for every week of the three main teaching periods through the year (i.e., summer school, first semester, second semester). Simply set the configuration as outlined below and make to regenerate the templates. */ /* Date of the Monday of the first academic week of the year. Teaching weeks start on Monday, so this is a convenient base point to start from. This will need to be updated annually. */ $first_monday = new DateTime( "2012-12-31" ); /* Teaching period configuration. This will need to be updated annually. It's easily extensible to a new teaching period simply by adding a new specification for that period. The key should be mixed-case alphanumeric (i.e., no whitespace, no punctuation or other special characters). The components of each period specification are: first_week: The academic week number of the first week of the period. last_week: The academic week number of the last week of the period. break_weeks: A list of breaks that occur during the teaching period. Each is specified by the start (break_start) and end (break_end) week. If a break is only one week long, then break_start and break_end should be equal. If there are no breaks in the teaching period, include a single break specification with both break_start and break_end set to zero. The list should ideally be in ascending order, but the script doesn't assume this and sorts the list anyway. Weeks are numbered by academic week number rather than week within the teaching period. */ $periods = array( 'SS' => array( 'first_week' => 2, 'last_week' => 7, 'break_weeks' => array( array( 'break_starts' => 0, 'break_ends' => 0, ), ), ), 'S1' => array( 'first_week' => 9, 'last_week' => 22, 'break_weeks' => array( array( 'break_starts' => 15, 'break_ends' => 15, ), ), ), 'S2' => array( 'first_week' => 28, 'last_week' => 41, 'break_weeks' => array( array( 'break_starts' => 35, 'break_ends' => 35, ), ), ), 'FY' => array( 'first_week' => 9, 'last_week' => 41, 'break_weeks' => array( array( 'break_starts' => 23, 'break_ends' => 27, ), array( 'break_starts' => 15, 'break_ends' => 15, ), array( 'break_starts' => 35, 'break_ends' => 35, ), ), ), ); // We need a condition to validate the period code in the templates. $period_condition = sprintf( "( @period = '%s' )", implode( "' ) or ( @period = '", array_keys( $periods ) ) ); // We also a list of valid period code values for the error string. $period_list = sprintf( '"%s"', implode( '", "', array_keys( $periods ) ) ); // The period and week variables are defined identically in both templates, so // let's define them just once here to ensure consistency. $shared_parameters = <<<EOT <xsl:with-param name="period"> <xsl:choose> <xsl:when test="{$period_condition}"> <xsl:value-of select="@period" /> </xsl:when> <!-- This also covers the case of @period being undefined. --> <xsl:otherwise> <xsl:message terminate="yes"> <xsl:text>Attribute "period" must be one of the values {$period_list}.</xsl:text> </xsl:message> </xsl:otherwise> </xsl:choose> </xsl:with-param> <xsl:with-param name="week"> <xsl:value-of select="@week" /> <xsl:if test="not( @week )"> <xsl:message terminate="yes"> <xsl:text>The "week" attribute is required.</xsl:text> </xsl:message> </xsl:if> </xsl:with-param> EOT; // Generate the file header and the wrapper templates. print<<<EOT <?xml version="1.0" encoding="utf-8"?> <!-- DO NOT EDIT!
