get_scantron_config($which) |
|
|
|
$which - the name of the configuration to parse from the file. |
|
|
|
Parses and returns the bubblesheet configuration line selected as a |
|
hash of configuration file fields. |
|
|
|
|
|
Returns: |
|
If the named configuration is not in the file, an empty |
|
hash is returned. |
|
|
|
a hash with the fields |
|
name - internal name for the this configuration setup |
|
description - text to display to operator that describes this config |
|
CODElocation - if 0 or the string 'none' |
|
- no CODE exists for this config |
|
if -1 || the string 'letter' |
|
- a CODE exists for this config and is |
|
a string of letters |
|
Unsupported value (but planned for future support) |
|
if a positive integer |
|
- The CODE exists as the first n items from |
|
the question section of the form |
|
if the string 'number' |
|
- The CODE exists for this config and is |
|
a string of numbers |
|
CODEstart - (only matter if a CODE exists) column in the line where |
|
the CODE starts |
|
CODElength - length of the CODE |
|
IDstart - column where the student/employee ID starts |
|
IDlength - length of the student/employee ID info |
|
Qstart - column where the information from the bubbled |
|
'questions' start |
|
Qlength - number of columns comprising a single bubble line from |
|
the sheet. (usually either 1 or 10) |
|
Qon - either a single character representing the character used |
|
to signal a bubble was chosen in the positional setup, or |
|
the string 'letter' if the letter of the chosen bubble is |
|
in the final, or 'number' if a number representing the |
|
chosen bubble is in the file (1->A 0->J) |
|
Qoff - the character used to represent that a bubble was |
|
left blank |
|
PaperID - if the scanning process generates a unique number for each |
|
sheet scanned the column that this ID number starts in |
|
PaperIDlength - number of columns that comprise the unique ID number |
|
for the sheet of paper |
|
FirstName - column that the first name starts in |
|
FirstNameLength - number of columns that the first name spans |
|
|
|
LastName - column that the last name starts in |
|
LastNameLength - number of columns that the last name spans |
|
BubblesPerRow - number of bubbles available in each row used to |
|
bubble an answer. (If not specified, 10 assumed). |

get_scantronformat_file($cdom) |
|
|
|
$cdom - the course's domain (optional); if not supplied, uses |
|
domain for current $env{'request.course.id'}. |
|
|
|
Returns an array containing lines from the scantron format file for |
|
the domain of the course. |
|
|
|
If a url for a custom.tab file is listed in domain's configuration.db, |
|
lines are from this file. |
|
|
|
Otherwise, if a default.tab has been published in RES space by the |
|
domainconfig user, lines are from this file. |
|
|
|
Otherwise, fall back to getting lines from the legacy file on the |
|
local server: /home/httpd/lonTabs/default_scantronformat.tab |
