-    INTRODUCTION
-    ------------
-
-    The task is to check the syntax of an input string. Input string is a stream of ASCII
-    characters terminated with a null-character ('\0'). Checking it using C language is
-    difficult and hard to implement without bugs. It is hard to maintain and make changes when
-    the syntax changes.
-
-    This is because of a high redundancy of the C code. Large blocks of code are duplicated with
-    only small changes. Even use of macros does not solve the problem because macros cannot
-    erase the complexity of the problem.
-
-    The resolution is to create a new language that will be highly oriented to our task. Once
-    we describe a particular syntax, we are done. We can then focus on the code that implements
-    the language. The size and complexity of it is relatively small than the code that directly
-    checks the syntax.
-
-    First, we must implement our new language. Here, the language is implemented in C, but it
-    could also be implemented in any other language. The code is listed below. We must take
-    a good care that it is bug free. This is simple because the code is simple and clean.
-
-    Next, we must describe the syntax of our new language in itself. Once created and checked
-    manually that it is correct, we can use it to check another scripts.
-
-    Note that our new language loading code does not have to check the syntax. It is because we
-    assume that the script describing itself is correct, and other scripts can be syntactically
-    checked by the former script. The loading code must only do semantic checking which leads us to
-    simple resolving references.
-
-    THE LANGUAGE
-    ------------
-
-    Here I will describe the syntax of the new language (further called "Synek"). It is mainly a
-    sequence of declarations terminated by a semicolon. The declaration consists of a symbol,
-    which is an identifier, and its definition. A definition is in turn a sequence of specifiers
-    connected with ".and" or ".or" operator. These operators cannot be mixed together in a one
-    definition. Specifier can be a symbol, string, character, character range or a special
-    keyword ".true" or ".false".
-
-    On the very beginning of the script there is a declaration of a root symbol and is in the form:
-        .syntax <root_symbol>;
-    The <root_symbol> must be on of the symbols in declaration sequence. The syntax is correct if
-    the root symbol evaluates to true. A symbol evaluates to true if the definition associated with
-    the symbol evaluates to true. Definition evaluation depends on the operator used to connect
-    specifiers in the definition. If ".and" operator is used, definition evaluates to true if and
-    only if all the specifiers evaluate to true. If ".or" operator is used, definition evalutes to
-    true if any of the specifiers evaluates to true. If definition contains only one specifier,
-    it is evaluated as if it was connected with ".true" keyword by ".and" operator.
-
-    If specifier is a ".true" keyword, it always evaluates to true.
-
-    If specifier is a ".false" keyword, it always evaluates to false. Specifier evaluates to false
-    when it does not evaluate to true.
-
-    Character range specifier is in the form:
-        '<first_character>' - '<second_character>'
-    If specifier is a character range, it evaluates to true if character in the stream is greater
-    or equal to <first_character> and less or equal to <second_character>. In that situation 
-    the stream pointer is advanced to point to next character in the stream. All C-style escape
-    sequences are supported although trigraph sequences are not. The comparisions are performed
-    on 8-bit unsigned integers.
-
-    Character specifier is in the form:
-        '<single_character>'
-    It evaluates to true if the following character range specifier evaluates to true:
-        '<single_character>' - '<single_character>'
-
-    String specifier is in the form:
-        "<string>"
-    Let N be the number of characters in <string>. Let <string>[i] designate i-th character in
-    <string>. Then the string specifier evaluates to true if and only if for i in the range [0, N)
-    the following character specifier evaluates to true:
-        '<string>[i]'
-    If <string>[i] is a quotation mark, '<string>[i]' is replaced with '\<string>[i]'.
-
-    Symbol specifier can be optionally preceded by a ".loop" keyword in the form:
-        .loop <symbol>                  (1)
-    where <symbol> is defined as follows:
-        <symbol> <definition>;          (2)
-    Construction (1) is replaced by the following code:
-        <symbol$1>
-    and declaration (2) is replaced by the following:
-        <symbol$1> <symbol$2> .or .true;
-        <symbol$2> <symbol> .and <symbol$1>;
-        <symbol> <definition>;
-
-    ESCAPE SEQUENCES
-    ----------------
-
-    Synek supports all escape sequences in character specifiers. The mapping table is listed below.
-    All occurences of the characters in the first column are replaced with the corresponding
-    character in the second column.
-
-        Escape sequence         Represents
-    ------------------------------------------------------------------------------------------------
-        \a                      Bell (alert)
-        \b                      Backspace
-        \f                      Formfeed
-        \n                      New line
-        \r                      Carriage return
-        \t                      Horizontal tab
-        \v                      Vertical tab
-        \'                      Single quotation mark
-        \"                      Double quotation mark
-        \\                      Backslash
-        \?                      Literal question mark
-        \ooo                    ASCII character in octal notation
-        \xhhh                   ASCII character in hexadecimal notation
-    ------------------------------------------------------------------------------------------------
-
-    RAISING ERRORS
-    --------------
-
-    Any specifier can be followed by a special construction that is executed when the specifier
-    evaluates to false. The construction is in the form:
-        .error <ERROR_TEXT>
-    <ERROR_TEXT> is an identifier declared earlier by error text declaration. The declaration is
-    in the form:
-        .errtext <ERROR_TEXT> "<error_desc>"
-    When specifier evaluates to false and this construction is present, parsing is stopped
-    immediately and <error_desc> is returned as a result of parsing. The error position is also
-    returned and it is meant as an offset from the beggining of the stream to the character that
-    was valid so far. Example:
-
-        (**** syntax script ****)
-
-        .syntax program;
-        .errtext MISSING_SEMICOLON      "missing ';'"
-        program         declaration .and .loop space .and ';' .error MISSING_SEMICOLON .and
-                        .loop space .and '\0';
-        declaration     "declare" .and .loop space .and identifier;
-        space           ' ';
-
-        (**** sample code ****)
-
-        declare foo ,
-
-    In the example above checking the sample code will result in error message "missing ';'" and
-    error position 12. The sample code is not correct. Note the presence of '\0' specifier to
-    assure that there is no code after semicolon - only spaces.
-    <error_desc> can optionally contain identifier surrounded by dollar signs $. In such a case,
-    the identifier and dollar signs are replaced by a string retrieved by invoking symbol with
-    the identifier name. The starting position is the error position. The lenght of the resulting
-    string is the position after invoking the symbol.
-
-    PRODUCTION
-    ----------
-
-    Synek not only checks the syntax but it can also produce (emit) bytes associated with specifiers
-    that evaluate to true. That is, every specifier and optional error construction can be followed
-    by a number of emit constructions that are in the form:
-        .emit <parameter>
-    <paramater> can be a HEX number, identifier, a star * or a dollar $. HEX number is preceded by
-    0x or 0X. If <parameter> is an identifier, it must be earlier declared by emit code declaration
-    in the form:
-        .emtcode <identifier> <hex_number>
-
-    When given specifier evaluates to true, all emits associated with the specifier are output
-    in order they were declared. A star means that last-read character should be output instead
-    of constant value. Example:
-
-        (**** syntax script ****)
-
-        .syntax foobar;
-        .emtcode WORD_FOO       0x01
-        .emtcode WORD_BAR       0x02
-        foobar      FOO .emit WORD_FOO .or BAR .emit WORD_BAR .or .true .emit 0x00;
-        FOO         "foo" .and SPACE;
-        BAR         "bar" .and SPACE;
-        SPACE       ' ' .or '\0';
-
-        (**** sample text 1 ****)
-
-        foo
-
-        (**** sample text 2 ****)
-
-        foobar
-
-    For both samples the result will be one-element array. For first sample text it will be
-    value 1, for second - 0. Note that every text will be accepted because of presence of
-    .true as an alternative.
-
-    Another example:
-
-        (**** syntax script ****)
-
-        .syntax declaration;
-        .emtcode VARIABLE       0x01
-        declaration     "declare" .and .loop space .and
-                        identifier .emit VARIABLE .and          (1)
-                        .true .emit 0x00 .and                   (2)
-                        .loop space .and ';';
-        space           ' ' .or '\t';
-        identifier      .loop id_char .emit *;                  (3)
-        id_char         'a'-'z' .or 'A'-'Z' .or '_';
-
-        (**** sample code ****)
-
-        declare    fubar;
-
-    In specifier (1) symbol <identifier> is followed by .emit VARIABLE. If it evaluates to
-    true, VARIABLE constant and then production of the symbol is output. Specifier (2) is used
-    to terminate the string with null to signal when the string ends. Specifier (3) outputs
-    all characters that make declared identifier. The result of sample code will be the
-    following array:
-        { 1, 'f', 'u', 'b', 'a', 'r', 0 }
-
-    If .emit is followed by dollar $, it means that current position should be output. Current
-    position is a 32-bit unsigned integer distance from the very beginning of the parsed string to
-    first character consumed by the specifier associated with the .emit instruction. Current
-    position is stored in the output buffer in Little-Endian convention (the lowest byte comes
-    first).

+    INTRODUCTION
+    ------------
+
+    The task is to check the syntax of an input string. Input string is a stream of ASCII
+    characters terminated with a null-character ('\0'). Checking it using C language is
+    difficult and hard to implement without bugs. It is hard to maintain and make changes when
+    the syntax changes.
+
+    This is because of a high redundancy of the C code. Large blocks of code are duplicated with
+    only small changes. Even use of macros does not solve the problem because macros cannot
+    erase the complexity of the problem.
+
+    The resolution is to create a new language that will be highly oriented to our task. Once
+    we describe a particular syntax, we are done. We can then focus on the code that implements
+    the language. The size and complexity of it is relatively small than the code that directly
+    checks the syntax.
+
+    First, we must implement our new language. Here, the language is implemented in C, but it
+    could also be implemented in any other language. The code is listed below. We must take
+    a good care that it is bug free. This is simple because the code is simple and clean.
+
+    Next, we must describe the syntax of our new language in itself. Once created and checked
+    manually that it is correct, we can use it to check another scripts.
+
+    Note that our new language loading code does not have to check the syntax. It is because we
+    assume that the script describing itself is correct, and other scripts can be syntactically
+    checked by the former script. The loading code must only do semantic checking which leads us to
+    simple resolving references.
+
+    THE LANGUAGE
+    ------------
+
+    Here I will describe the syntax of the new language (further called "Synek"). It is mainly a
+    sequence of declarations terminated by a semicolon. The declaration consists of a symbol,
+    which is an identifier, and its definition. A definition is in turn a sequence of specifiers
+    connected with ".and" or ".or" operator. These operators cannot be mixed together in a one
+    definition. Specifier can be a symbol, string, character, character range or a special
+    keyword ".true" or ".false".
+
+    On the very beginning of the script there is a declaration of a root symbol and is in the form:
+        .syntax <root_symbol>;
+    The <root_symbol> must be on of the symbols in declaration sequence. The syntax is correct if
+    the root symbol evaluates to true. A symbol evaluates to true if the definition associated with
+    the symbol evaluates to true. Definition evaluation depends on the operator used to connect
+    specifiers in the definition. If ".and" operator is used, definition evaluates to true if and
+    only if all the specifiers evaluate to true. If ".or" operator is used, definition evalutes to
+    true if any of the specifiers evaluates to true. If definition contains only one specifier,
+    it is evaluated as if it was connected with ".true" keyword by ".and" operator.
+
+    If specifier is a ".true" keyword, it always evaluates to true.
+
+    If specifier is a ".false" keyword, it always evaluates to false. Specifier evaluates to false
+    when it does not evaluate to true.
+
+    Character range specifier is in the form:
+        '<first_character>' - '<second_character>'
+    If specifier is a character range, it evaluates to true if character in the stream is greater
+    or equal to <first_character> and less or equal to <second_character>. In that situation 
+    the stream pointer is advanced to point to next character in the stream. All C-style escape
+    sequences are supported although trigraph sequences are not. The comparisions are performed
+    on 8-bit unsigned integers.
+
+    Character specifier is in the form:
+        '<single_character>'
+    It evaluates to true if the following character range specifier evaluates to true:
+        '<single_character>' - '<single_character>'
+
+    String specifier is in the form:
+        "<string>"
+    Let N be the number of characters in <string>. Let <string>[i] designate i-th character in
+    <string>. Then the string specifier evaluates to true if and only if for i in the range [0, N)
+    the following character specifier evaluates to true:
+        '<string>[i]'
+    If <string>[i] is a quotation mark, '<string>[i]' is replaced with '\<string>[i]'.
+
+    Symbol specifier can be optionally preceded by a ".loop" keyword in the form:
+        .loop <symbol>                  (1)
+    where <symbol> is defined as follows:
+        <symbol> <definition>;          (2)
+    Construction (1) is replaced by the following code:
+        <symbol$1>
+    and declaration (2) is replaced by the following:
+        <symbol$1> <symbol$2> .or .true;
+        <symbol$2> <symbol> .and <symbol$1>;
+        <symbol> <definition>;
+
+    Synek supports also a register mechanizm. User can, in its SYN file, declare a number of
+    registers that can be accessed in the syn body. Each reg has its name and a default value.
+    The register is one byte wide. The C code can change the default value by calling
+    grammar_set_reg8() with grammar id, register name and a new value. As we know, each rule is
+    a sequence of specifiers joined with .and or .or operator. And now each specifier can be
+    prefixed with a condition expression in a form ".if (<reg_name> <operator> <hex_literal>)"
+    where <operator> can be == or !=. If the condition evaluates to false, the specifier
+    evaluates to .false. Otherwise it evalutes to the specifier.
+
+    ESCAPE SEQUENCES
+    ----------------
+
+    Synek supports all escape sequences in character specifiers. The mapping table is listed below.
+    All occurences of the characters in the first column are replaced with the corresponding
+    character in the second column.
+
+        Escape sequence         Represents
+    ------------------------------------------------------------------------------------------------
+        \a                      Bell (alert)
+        \b                      Backspace
+        \f                      Formfeed
+        \n                      New line
+        \r                      Carriage return
+        \t                      Horizontal tab
+        \v                      Vertical tab
+        \'                      Single quotation mark
+        \"                      Double quotation mark
+        \\                      Backslash
+        \?                      Literal question mark
+        \ooo                    ASCII character in octal notation
+        \xhhh                   ASCII character in hexadecimal notation
+    ------------------------------------------------------------------------------------------------
+
+    RAISING ERRORS
+    --------------
+
+    Any specifier can be followed by a special construction that is executed when the specifier
+    evaluates to false. The construction is in the form:
+        .error <ERROR_TEXT>
+    <ERROR_TEXT> is an identifier declared earlier by error text declaration. The declaration is
+    in the form:
+        .errtext <ERROR_TEXT> "<error_desc>"
+    When specifier evaluates to false and this construction is present, parsing is stopped
+    immediately and <error_desc> is returned as a result of parsing. The error position is also
+    returned and it is meant as an offset from the beggining of the stream to the character that
+    was valid so far. Example:
+
+        (**** syntax script ****)
+
+        .syntax program;
+        .errtext MISSING_SEMICOLON      "missing ';'"
+        program         declaration .and .loop space .and ';' .error MISSING_SEMICOLON .and
+                        .loop space .and '\0';
+        declaration     "declare" .and .loop space .and identifier;
+        space           ' ';
+
+        (**** sample code ****)
+
+        declare foo ,
+
+    In the example above checking the sample code will result in error message "missing ';'" and
+    error position 12. The sample code is not correct. Note the presence of '\0' specifier to
+    assure that there is no code after semicolon - only spaces.
+    <error_desc> can optionally contain identifier surrounded by dollar signs $. In such a case,
+    the identifier and dollar signs are replaced by a string retrieved by invoking symbol with
+    the identifier name. The starting position is the error position. The lenght of the resulting
+    string is the position after invoking the symbol.
+
+    PRODUCTION
+    ----------
+
+    Synek not only checks the syntax but it can also produce (emit) bytes associated with specifiers
+    that evaluate to true. That is, every specifier and optional error construction can be followed
+    by a number of emit constructions that are in the form:
+        .emit <parameter>
+    <paramater> can be a HEX number, identifier, a star * or a dollar $. HEX number is preceded by
+    0x or 0X. If <parameter> is an identifier, it must be earlier declared by emit code declaration
+    in the form:
+        .emtcode <identifier> <hex_number>
+
+    When given specifier evaluates to true, all emits associated with the specifier are output
+    in order they were declared. A star means that last-read character should be output instead
+    of constant value. Example:
+
+        (**** syntax script ****)
+
+        .syntax foobar;
+        .emtcode WORD_FOO       0x01
+        .emtcode WORD_BAR       0x02
+        foobar      FOO .emit WORD_FOO .or BAR .emit WORD_BAR .or .true .emit 0x00;
+        FOO         "foo" .and SPACE;
+        BAR         "bar" .and SPACE;
+        SPACE       ' ' .or '\0';
+
+        (**** sample text 1 ****)
+
+        foo
+
+        (**** sample text 2 ****)
+
+        foobar
+
+    For both samples the result will be one-element array. For first sample text it will be
+    value 1, for second - 0. Note that every text will be accepted because of presence of
+    .true as an alternative.
+
+    Another example:
+
+        (**** syntax script ****)
+
+        .syntax declaration;
+        .emtcode VARIABLE       0x01
+        declaration     "declare" .and .loop space .and
+                        identifier .emit VARIABLE .and          (1)
+                        .true .emit 0x00 .and                   (2)
+                        .loop space .and ';';
+        space           ' ' .or '\t';
+        identifier      .loop id_char .emit *;                  (3)
+        id_char         'a'-'z' .or 'A'-'Z' .or '_';
+
+        (**** sample code ****)
+
+        declare    fubar;
+
+    In specifier (1) symbol <identifier> is followed by .emit VARIABLE. If it evaluates to
+    true, VARIABLE constant and then production of the symbol is output. Specifier (2) is used
+    to terminate the string with null to signal when the string ends. Specifier (3) outputs
+    all characters that make declared identifier. The result of sample code will be the
+    following array:
+        { 1, 'f', 'u', 'b', 'a', 'r', 0 }
+
+    If .emit is followed by dollar $, it means that current position should be output. Current
+    position is a 32-bit unsigned integer distance from the very beginning of the parsed string to
+    first character consumed by the specifier associated with the .emit instruction. Current
+    position is stored in the output buffer in Little-Endian convention (the lowest byte comes
+    first).
