For example, your can make simple ANSI C syntax highlight like this:
```c
char * separator = ".,:;<=>+-*/%!&~^?|()[]{}'\" \t\r\n";
char * separators = ".,:;<=>+-*/%!&~^?|()[]{}'\" \t\r\n";
char * c_keywords [32] = {

"register", "volatile", "auto", "const", "static", "extern", "if", "else",
"do", "while", "for", "continue", "switch", "case", "default", "break",
"enum", "union", "struct", "typedef", "goto", "void", "return", "sizeof",
"char", "short", "int", "long", "signed", "unsigned", "float", "double"
};

(void) syntax_define (0, 0, "#", "\n", '\\', COLOUR_PINK, EFFECT_BOLD);
(void) syntax_define (0, 0, "//", "\n", '\0', COLOUR_GREY, EFFECT_BOLD);

(void) syntax_define (1, 0, ".,:;<=>+-*/%!&~^?|()[]{}", "", '\0', COLOUR_CYAN, EFFECT_NORMAL);
With using helper 'syntax_define_*' functions:
```c
syntax_define_separators (separators);
syntax_define_default (COLOUR_RED, EFFECT_NORMAL, COLOUR_CYAN, EFFECT_BOLD);
syntax_define_range ("/*", "*/", '\0', COLOUR_GREY, EFFECT_BOLD);
syntax_define_range ("//", "\n", '\0', COLOUR_GREY, EFFECT_BOLD);
syntax_define_range ("#", "\n", '\\', COLOUR_PINK, EFFECT_NORMAL);
syntax_define_range ("'", "'", '\\', COLOUR_PINK, EFFECT_BOLD);
syntax_define_operators (".,:;<=>+*-/%!&~^?|()[]{}", COLOUR_BLUE, EFFECT_BOLD);
syntax_define_words (keywords, 32, COLOUR_BLUE, EFFECT_NORMAL);
```
Or using core 'syntax_push' functions:
```c
(void) syntax_insert (1, 0, " \t\r\n", "", '\0', COLOUR_WHITE, EFFECT_NORMAL);
(void) syntax_insert (0, 0, "#", "\n", '\\', COLOUR_PINK, EFFECT_BOLD);
(void) syntax_insert (0, 0, "//", "\n", '\0', COLOUR_GREY, EFFECT_BOLD);
(void) syntax_insert (0, 0, "/*", "*/", '\0', COLOUR_GREY, EFFECT_BOLD);
(void) syntax_insert (0, 0, "'", "'", '\\', COLOUR_RED, EFFECT_NORMAL);
(void) syntax_insert (0, 0, "\"", "\"", '\\', COLOUR_RED, EFFECT_BOLD);
(void) syntax_insert (1, 0, ".,:;<=>+-*/%!&~^?|()[]{}", "", '\0', COLOUR_CYAN, EFFECT_NORMAL);
for (word = 0; word != 32; ++word) {
(void) syntax_define (0, 1, c_keywords [word], separator, '\0', COLOUR_BLUE, EFFECT_BOLD);
(void) syntax_insert (0, 1, c_keywords [word], separator, '\0', COLOUR_BLUE, EFFECT_BOLD);
}
(void) syntax_define (1, 1, "0123456789", separator, '\0', COLOUR_CYAN, EFFECT_BOLD);
(void) syntax_define (1, 1, "ABCDEFGHIJKLMNOPQRSTUVWXYZ", separator, '\0', COLOUR_PINK, EFFECT_ITALIC);
(void) syntax_define (1, 1, "abcdefghijklmnopqrstuvwxyz", separator, '\0', COLOUR_WHITE, EFFECT_ITALIC);
(void) syntax_define (0, 1, "_", separator, '\0', COLOUR_PINK, EFFECT_BOLD);
(void) syntax_insert (1, 1, "0123456789", separator, '\0', COLOUR_CYAN, EFFECT_BOLD);
(void) syntax_insert (1, 1, "ABCDEFGHIJKLMNOPQRSTUVWXYZ", separator, '\0', COLOUR_PINK, EFFECT_ITALIC);
(void) syntax_insert (1, 1, "abcdefghijklmnopqrstuvwxyz", separator, '\0', COLOUR_WHITE, EFFECT_ITALIC);
(void) syntax_insert (0, 1, "_", separator, '\0', COLOUR_PINK, EFFECT_BOLD);
```
If you want to do parsing, counting, tokenization, you can use return value of 'syntax_push'...
