! 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 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.
