+<title>RELAX NG Test Suite</title>
+</head>
+<body>
+
+<p>This is a test suite for the final version of the <a
+href="http://www.oasis-open.org/committees/relax-ng/spec-20011203.html">RELAX
+NG 1.0 Specification</a>.</p>
+
+<p>The test suite consists of a single XML file <a
+href="spectest.xml">spectest.xml</a>, which includes over 300 test
+cases. Each test case consists of a correct or incorrect RELAX NG
+schema and zero or more valid or invalid instances. A RELAX NG <a
+href="testSuite.rng">schema</a> is available that specifies the format
+of the test suite.</p>
+
+<p>In order to run the test suite it may be convenient to split it up
+into separate files. An XSLT stylesheet <a
+href="split.xsl">split.xsl</a> is included to do this. This stylesheet
+uses <a href="http://saxon.sourceforge.net/">SAXON</a> extensions.  <a
+href="http://www.thaiopensource.com/relaxng/jing.html">Jing</a>
+includes a class to run the test suite after it has been split up.
+The class is <code>com.thaiopensource.relaxng.util.TestDriver</code>.
+This class must be invoked with two arguments.  The first argument is
+a log file for expected errors.  The second argument is the directory
+containing the split-up test suite.</p>

+# This module automatically constructs a lexical analysis module from regular
+# expression rules defined in a user-defined module.  The idea is essentially the same
+# as that used in John Aycock's Spark framework, but the implementation works
+# at the module level rather than requiring the use of classes.
+#
+# This module tries to provide an interface that is closely modeled after
+# the traditional lex interface in Unix.  It also differs from Spark
+# in that:
+#
+#   -  It provides more extensive error checking and reporting if
+#      the user supplies a set of regular expressions that can't
+#      be compiled or if there is any other kind of a problem in
+#      the specification.
+#
+#   -  The interface is geared towards LALR(1) and LR(1) parser
+#      generators.  That is tokens are generated one at a time
+#      rather than being generated in advanced all in one step.
+#
+# There are a few limitations of this module
+#
+#   -  The module interface makes it somewhat awkward to support more
+#      than one lexer at a time.  Although somewhat inelegant from a
+#      design perspective, this is rarely a practical concern for
+#      most compiler projects.
+#
+#   -  The lexer requires that the entire input text be read into
+#      a string before scanning.  I suppose that most machines have
+#      enough memory to make this a minor issues, but it makes
+#      the lexer somewhat difficult to use in interactive sessions
+#      or with streaming data.
+#

+lex.py
+
+This module builds lex-like scanners based on regular expression rules.
+To use the module, simply write a collection of regular expression rules
+and actions like this:
+
+# lexer.py
+import lex
+
+# Define a list of valid tokens
+tokens = (
+    'IDENTIFIER', 'NUMBER', 'PLUS', 'MINUS'
+    )
+
+# Define tokens as functions
+def t_IDENTIFIER(t):
+    r' ([a-zA-Z_](\w|_)* '
+    return t
+
+def t_NUMBER(t):
+    r' \d+ '
+    return t
+
+# Some simple tokens with no actions
+t_PLUS = r'\+'
+t_MINUS = r'-'
+
+# Initialize the lexer
+lex.lex()
+
+The tokens list is required and contains a complete list of all valid
+token types that the lexer is allowed to produce.  Token types are
+restricted to be valid identifiers.  This means that 'MINUS' is a valid
+token type whereas '-' is not.
+
+Rules are defined by writing a function with a name of the form
+t_rulename.  Each rule must accept a single argument which is
+a token object generated by the lexer. This token has the following
+attributes:
+
+    t.type   = type string of the token.  This is initially set to the
+               name of the rule without the leading t_
+    t.value  = The value of the lexeme.
+    t.lineno = The value of the line number where the token was encountered
+    
+For example, the t_NUMBER() rule above might be called with the following:
+    
+    t.type  = 'NUMBER'
+    t.value = '42'
+    t.lineno = 3
+
+Each rule returns the token object it would like to supply to the
+parser.  In most cases, the token t is returned with few, if any
+modifications.  To discard a token for things like whitespace or
+comments, simply return nothing.  For instance:
+
+def t_whitespace(t):
+    r' \s+ '
+    pass
+
+For faster lexing, you can also define this in terms of the ignore set like this:
+
+t_ignore = ' \t'
+
+The characters in this string are ignored by the lexer. Use of this feature can speed
+up parsing significantly since scanning will immediately proceed to the next token.
+
+lex requires that the token returned by each rule has an attribute
+t.type.  Other than this, rules are free to return any kind of token
+object that they wish and may construct a new type of token object
+from the attributes of t (provided the new object has the required
+type attribute).
+
+If illegal characters are encountered, the scanner executes the
+function t_error(t) where t is a token representing the rest of the
+string that hasn't been matched.  If this function isn't defined, a
+LexError exception is raised.  The .text attribute of this exception
+object contains the part of the string that wasn't matched.
+
+The t.skip(n) method can be used to skip ahead n characters in the
+input stream.  This is usually only used in the error handling rule.
+For instance, the following rule would print an error message and
+continue:
+
+def t_error(t):
+    print "Illegal character in input %s" % t.value[0]
+    t.skip(1)
+
+Of course, a nice scanner might wish to skip more than one character
+if the input looks very corrupted.
+
+The lex module defines a t.lineno attribute on each token that can be used
+to track the current line number in the input.  The value of this
+variable is not modified by lex so it is up to your lexer module
+to correctly update its value depending on the lexical properties
+of the input language.  To do this, you might write rules such as
+the following:
+
+def t_newline(t):
+    r' \n+ '
+    t.lineno += t.value.count("\n")
+
+To initialize your lexer so that it can be used, simply call the lex.lex()
+function in your rule file.  If there are any errors in your
+specification, warning messages or an exception will be generated to
+alert you to the problem.
+
+(dave: this needs to be rewritten)
+To use the newly constructed lexer from another module, simply do
+this:
+
+    import lex
+    import lexer
+    plex.input("position = initial + rate*60")
+
+    while 1:
+        token = plex.token()       # Get a token
+        if not token: break        # No more tokens
+        ... do whatever ...
+
+Assuming that the module 'lexer' has initialized plex as shown
+above, parsing modules can safely import 'plex' without having
+to import the rule file or any additional imformation about the
+scanner you have defined.
