58: =head1 INTRODUCTION
59:
60: This module publishes a directory of files.
61:
62: This is part of the LearningOnline Network with CAPA project
63: described at http://www.lon-capa.org.
64:
65: =head1 HANDLER SUBROUTINE
66:
67: This routine is called by Apache and mod_perl.
68:
69: =over 4
70:
71: =item *
72:
73: read in information
74:
75: =item *
76:
77: start page output
78:
79: =item *
80:
81: run through list of files and attempt to publish unhidden files
82:
83: =back
84:
85: =head2 OTHER SUBROUTINES:
86:
87: =head3 startpage($r, $uame, $udom, $thisdisfn)
88:
89: Output the header of the page. This includes:
90: - The HTML header
91: - The H1/H3 stuff which includes the directory.
92:
93: startpage($r, $uame, $udom, $thisdisfn);
94: $r - The apache request object.
95: $uname - User name.
96: $udom - Domain name the user is logged in under.
97: $thisdisfn - Displayable version of the filename.
98:
99: =head3 getTitleString($fullname)
100:
101: Get the title string or "[untitled]" if the file has no title metadata:
102: Without the latter substitution, it's impossible to examine metadata for
103: untitled resources. Resources may be legitimately untitled, to prevent
104: searches from locating them.
105:
106: $str = getTitleString($fullname);
107: $fullname - Fully qualified filename to check.
108:
109: =head3 putdirectory(r, base, here, dirname, modtime)
110:
111: Put out a directory table row:
112:
113: putdirectory($r, $base, $here, $dirname, $modtime)
114: $r - Apache request object.
115: $reqfile - File in request.
116: $here - Where we are in directory tree.
117: $dirname - Name of directory special file.
118: $modtime - Encoded modification time.
119:
120: =head3 CategorizeFiles($location, $files)
121:
122: Categorize files in the directory.
123: For each file in a list of files in a file directory,
124: the file categorized as one of:
125: - directory
126: - sequence
127: - problem
128: - Other resource.
129:
130: For each file the modification date is determined as well.
131: Returned is a list of sublists:
132: (directories, sequences, problems, other)
133: each of the sublists contains entries of the following form (sorted by filename):
134: (filename, typecode, lastmodtime)
135:
136: $list = CategorizeFiles($location, $files)
137: $location - Directory in which the files live (relative to our execution)
138: $files - list of files.
