102 | =head1 DESCRIPTION |
|
|
103 | |
|
|
104 | The WeBWorK::CourseEnvironment module reads the system-wide F<global.conf> and |
|
|
105 | course-specific F<course.conf> files used by WeBWorK to calculate and store |
|
|
106 | settings needed throughout the system. The F<.conf> files are perl source files |
|
|
107 | that can contain any code allowed under the default safe compartment opset. |
|
|
108 | After evaluation of both files, any package variables are copied out of the |
|
|
109 | safe compartment into a hash. This hash becomes the course environment. |

|
|
116 | |
|
|
117 | The C<new> method finds the file F<conf/global.conf> relative to the given ROOT |
|
|
118 | directory. After reading this file, it uses the C<$courseFiles{environment}> |
|
|
119 | variable, if present, to locate the course environment file. If found, the file |
|
|
120 | is read and added to the environment. |

124 | =head1 ACCESS |
|
|
125 | |
|
|
126 | There are no formal accessor methods. However, since the course environemnt is |
|
|
127 | a hash of hashes and arrays, is exists as the self hash of an instance |
|
|
128 | variable: |
|
|
129 | |
|
|
130 | $courseEnvironment->{someKey}->{someOtherKey}; |
