- 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).

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 $, it means that current position should be output. Current + position is a 32-bit unsigned integer distance from the very beginning of the parsed string to + first character consumed by the specifier associated with the .emit instruction. Current + position is stored in the output buffer in Little-Endian convention (the lowest byte comes + first). +*/ + +static void mem_free (void **); + +/* + internal error messages +*/ +static const byte *OUT_OF_MEMORY = (byte *) "internal error 1001: out of physical memory"; +static const byte *UNRESOLVED_REFERENCE = (byte *) "internal error 1002: unresolved reference '$'"; +static const byte *INVALID_GRAMMAR_ID = (byte *) "internal error 1003: invalid grammar object"; +static const byte *INVALID_REGISTER_NAME = (byte *) "internal error 1004: invalid register name: '$'"; + +static const byte *error_message = NULL; +static byte *error_param = NULL; /* this is inserted into error_message in place of $ */ +static int error_position = -1; + +static byte *unknown = (byte *) "???"; + +static void clear_last_error () +{ + /* reset error message */ + error_message = NULL; + + /* free error parameter - if error_param is a "???" don't free it - it's static */ + if (error_param != unknown) + mem_free ((void **) &error_param); + else + error_param = NULL; + + /* reset error position */ + error_position = -1; +} + +static void set_last_error (const byte *msg, byte *param, int pos) +{ + /* error message can only be set only once */ + if (error_message != NULL) + { + mem_free (¶m); + return; + } + + error_message = msg; + + if (param != NULL) + error_param = param; + else + error_param = unknown; + + error_position = pos; +} + +/* + memory management routines +*/ +static void *mem_alloc (size_t size) +{ + void *ptr = grammar_alloc_malloc (size); + if (ptr == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return ptr; +} + +static void *mem_copy (void *dst, const void *src, size_t size) +{ + return grammar_memory_copy (dst, src, size); +} + +static void mem_free (void **ptr) +{ + grammar_alloc_free (*ptr); + *ptr = NULL; +} + +static void *mem_realloc (void *ptr, size_t old_size, size_t new_size) +{ + void *ptr2 = grammar_alloc_realloc (ptr, old_size, new_size); + if (ptr2 == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return ptr2; +} + +static byte *str_copy_n (byte *dst, const byte *src, size_t max_len) +{ + return grammar_string_copy_n (dst, src, max_len); +} + +static byte *str_duplicate (const byte *str) +{ + byte *new_str = grammar_string_duplicate (str); + if (new_str == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return new_str; +} + +static int str_equal (const byte *str1, const byte *str2) +{ + return grammar_string_compare (str1, str2) == 0; +} + +static int str_equal_n (const byte *str1, const byte *str2, unsigned int n) +{ + return grammar_string_compare_n (str1, str2, n) == 0; +} + +static unsigned int str_length (const byte *str) +{ + return grammar_string_length (str); +} + +/* + string to byte map typedef +*/ +typedef struct map_byte_ +{ + byte *key; + byte data; + struct map_byte_ *next; +} map_byte; + +static void map_byte_create (map_byte **ma) +{ + *ma = mem_alloc (sizeof (map_byte)); + if (*ma) + { + (**ma).key = NULL; + (**ma).data = '\0'; + (**ma).next = NULL; + } +} + +/* XXX unfold the recursion */ +static void map_byte_destroy (map_byte **ma) +{ + if (*ma) + { + map_byte_destroy (&(**ma).next); + mem_free ((void **) &(**ma).key); + mem_free ((void **) ma); + } +} + +static void map_byte_append (map_byte **ma, map_byte **nm) +{ + while (*ma) + ma = &(**ma).next; + *ma = *nm; +} + +/* + searches the map for the specified key, + returns pointer to the element with the specified key if it exists + returns NULL otherwise +*/ +map_byte *map_byte_locate (map_byte **ma, const byte *key) +{ + while (*ma) + { + if (str_equal ((**ma).key, key)) + return *ma; + + ma = &(**ma).next; + } + + set_last_error (UNRESOLVED_REFERENCE, str_duplicate (key), -1); + return NULL; +} + +/* + searches the map for specified key, + if the key is matched, *data is filled with data associated with the key, + returns 0 if the key is matched, + returns 1 otherwise +*/ +static int map_byte_find (map_byte **ma, const byte *key, byte *data) +{ + map_byte *found = map_byte_locate (ma, key); + if (found != NULL) + { + *data = found->data; + + return 0; + } + + return 1; +} + +/* + regbyte context typedef + + Each regbyte consists of its name and a default value.
