- 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).
