 # libhl 
 
 ## API
+```C
 	int hl_init(void);
 	int hl_deinit(void);
+```
 These functions are responsible for the library's "life time".
 `hl_init()` must be called before any other library function.
 `hl_deinit()` will ensure all occupied memory is freed.
 
+```C
 	void render_string(const char * const string, const char * const mode);
+```
 This function matches _string_ against all known highlighting rules and dispatches the appropriate callback depending on _mode_.
 
+```C
 	typedef void (*attribute_callback_t)(const char * const string, const int length, void * const attributes);
+```
 The type used for defining appropriate callbacks for render_string().
 + string     - string to be outputed
 + length     - number of characters that matched a highlighting rule
 + attributes - arbitrary data associated with the matched rule; intended to hold color/font information for example

+```C
+typedef struct {
+	char * key;
+	attribute_callback_t callback;
+} display_t;
+```
 The type for defining display modes.
 
 	void new_display_mode(display_t * mode);
 This is how you append a display mode that render_string() will search based on _.key_.
 
+```C
 	typedef enum {
 		KEYSYMBOL,
 		KEYWORD,
 		MATCH,
 		REGION
 	} token_type_t;

 These are the valid type of distinct token types.

 + REGION    - a regular expression where the starting and ending patters are to be distinguished from the contents
 
 The universal way to add a new pattern to be recognized is with:
-
+```C
 	token * new_token(const char * const syntax, const token_type_t t, const hl_group_t * const g);
-
+```
 There are also convinience functions:
-
+```C
 	// NOTE: the return value is the number tokens successfully inserted
 	int new_keyword_tokens(const char * const * words, hl_group_t * const g);	// _words_ must be NULL terminated
 	int new_syntax_character_tokens(const char * const chars, hl_group_t * const g);
 
+```
 The regex engine used for MATCHes is Jeger by default, emulating Vim regex.
 However the regex engine can be overridden:
-
+```C
 	// ?!
+```

 General purpose highlighter (and demo program for libhl).
 
 ## Usage
 hl will read from stdin and write to stdout.
+```bash
 	hl < source/main.c
+```
 
 ### Cli Options
+```bash
 	-h          : display help message
 	-F <dir>    : syntax file look up directory
 	-s <syntax> : specify syntax to load
+```
 
 ### Environment variables
+```bash
 	HL_HOME	: default directory to load syntax files from
+```
