String Handling Routines

Simple

string to_lower_case( string )

Converts all upper-case alphabetic characters to lower-case.

string to_upper_case( string )

Converts all lower-case alphabetic characters to upper-case.

string to_url( location )

Returns the url which is accessed to visit the specified location.

boolean contains_text( string, string )

Returns true if the second string is found as a substring of the first.

int extract_meat( string )

Returns the number of meat embedded in a string.

int [item] extract_items()

Parses a string for items and their amounts (handles plural & singular forms) and returns the results as a map.

int length( string )

Returns the number of characters in the specified string.

string char_at( string, index )

Returns the character at a specified index in a string.

int index_of( string, string, [int] )

Returns the position of the second string in the first (or -1 if not found), optionally starting its search from a given position.

int last_index_of( string, string )

Returns the last index of the second string in the first.

string substring( string, int, [int] )

Returns the substring of the specified string, starting from a specified position, and optionally ending before a specified position (defaults to remainder of string).

buffer replace_string( buffer, string, string )

buffer replace_string( string, string, string )

Replaces all text in the first string that matches the second with the third.

buffer replace( buffer, int, int, string )

Replaces all text from the first index to the second index with the supplied string.

string url_encode( string )

Converts a string into a URL formatted string.

string url_decode( string )

Converts a URL formatted string into regular text.

string [int] split_string( string, [string] )

Splits apart the first string at line-breaks or using an optionally supplied delimeter and returns an integer-keyed map of the result.

string [int] session_logs( [string], int )

Gives access to sessions logs. And stuff. [1]

buffer append( buffer, string )

Appends the string to the end of the buffer.

void set_length( buffer, int )

Changes the length of a buffer.

buffer delete( buffer, int, int )

Deletes the specified portion of the buffer.

buffer insert( buffer, int, string )

Inserts the string at the specified point in the buffer.

Regular Expressions

It is advised that anyone desiring to use these functions should first understand the basics of Regular Expressions and how these functions implement that language.

matcher create_matcher( string, string )

Creates a matcher from a pattern and input string.

matcher reset( matcher, [string] )

Resets matcher to search from beginning of string, possibly with new input.

int group_count( matcher )

Returns the number of capturing groups in the pattern.

string [int,int] group_string( string, string )

Maps a string to an aggregate (see page for details). [2]

int start( matcher, [int] )

Returns the starting index of the previous or specified capturing group.

int end( matcher, [int] )

Returns the ending index of the previous or specified capturing group plus 1.

boolean find( matcher )

Finds the next instance of the pattern or returns false if no more matches exist.

string group( matcher, [int] )

Returns the contents of an indicated capturing group (starting at 1) or the entire pattern if not indicated.

string replace_all( matcher, string )

Replaces all pattern matches with a given string.

string replace_first( matcher, string )

Replaces the first pattern match with a given string.

buffer append_replacement( matcher, buffer, string )

buffer append_tail( matcher, buffer )

Appends the text returned by a matcher to the end of the buffer.
