40 .Nd random knowledge tests
45 .Op Ar question answer
49 utility tests your knowledge of random facts.
50 It has a database of subjects from which you can choose.
53 displays the list of available subjects.
55 The options are as follows:
56 .Bl -tag -width indent
58 Use tutorial mode, in which questions are repeated later if you didn't get
59 them right the first time, and new questions are presented less frequently
60 to help you learn the older ones.
62 Specify an alternative index file.
65 Subjects are divided into categories.
66 You can pick any two categories from the same subject.
68 will ask questions from the first category and it expects answers from
70 For example, the command
71 .Dq quiz victim killer
72 asks questions which are the names of victims, and expects you to answer
73 with the cause of their untimely demise, whereas the command
74 .Dq quiz killer victim
75 works the other way around.
77 If you get the answer wrong,
80 To see the right answer, enter a blank line.
81 .Ss Index and Data File Syntax
82 The index and data files have a similar syntax.
83 Lines in them consist of several categories separated by colons.
84 The categories are regular expressions formed using the following
87 .Bl -tag -width "pat|pat" -compact -offset indent
93 delimiters, as in pat[pat|pat]pat
96 In an index file, each line represents a subject.
97 The first category in each subject is the pathname of the data file for
99 The remaining categories are regular expressions for the titles of each
100 category in the subject.
102 In data files, each line represents a question/answer set.
103 Each category is the information for the question/answer for that category.
105 The backslash character (``\e'') is used to quote syntactically significant
106 characters, or at the end of a line to signify that a continuation line
109 If either a question or its answer is empty,
111 will refrain from asking it.
113 .Bl -tag -width /usr/share/games/quiz.db -compact
114 .It Pa /usr/share/games/quiz.db
115 The default index and data files.
119 is pretty cynical about certain subjects.
