Typos
1: \label{Authoring_Scripting_Tags}
2:
3: \begin{itemize}
4: \item \textbf{display}\index{display}: The intervening Perl script is evaluated
5: in the safe space and the return value of the script replaces the
6: entire tag.
7: \item \textbf{import}\index{import}: Causes the parse to read in the file
8: named in the body of the tag and parse it as if the entire text of
9: the file had existed at location of the tag.
10: \item \textbf{parserlib}\index{parserlib}: the enclosed filename contains
11: definitions for new tags.
12: \item \textbf{script}\index{script}: If the attribute \textbf{type} is
13: set to {}``loncapa/perl'' the enclosed data is a Perl script which
14: is evaluated inside the Perl Safe space. The return value of the script
15: is ignored.
16: \item \textbf{scriptlib}\index{scriptlib}: The enclosed filename contains
17: Perl code to run in the safe space.
18: \item \textbf{block}\index{block}: Has a required argument \textbf{condition}
19: that is evaluated. If the condition is true everything inside the
20: tag is evaluated, otherwise everything inside the block tag is skipped.
21: \item \textbf{notsolved}\index{notsolved}: Everything inside the tag is
22: skipped if the problem is {}``solved''.
23: \item \textbf{postanswerdate}\index{postanswerdate}: Everything inside
24: the tag is skipped if the problem is before the answer date.
25: \item \textbf{preduedate}\index{preduedate}: Everything inside the tag
26: is skipped if the problem is after the due date
27: \item \textbf{randomlist}\index{randomlist}: The enclosed tags are parsed
28: in a stable random order. The optional attribute \textbf{show} restricts
29: the number of tags inside that are actually parsed to no more than
30: \textbf{show}.
31: \item \textbf{solved}\index{solved}: Everything inside the tag is skipped
32: if the problem is {}``not solved''.
33: \item \textbf{while}\index{while}: Implements a while loop. The required
34: attribute \textbf{condition} is a Perl scriptlet that when evaluated
35: results in a true or false value. On true the entirety of the text
36: between the whiles is parsed. The condition is tested again, etc.
37: If false it goes to the next tag.
38: \end{itemize}
