Editing WoW:Lua functions (section)

=== String ===
These string functions are shorthand references to the Lua string library, which is available via "string.". See [http://lua-users.org/wiki/StringLibraryTutorial StringLibraryTutorial] for more info.

: [[API format|format]](formatstring[, value[, ...]]) - Return a formatted string using values passed in.
: [[API gsub|gsub]](string,pattern,replacement[, limitCount]) - Globally substitute pattern for replacement in string.
: [[API strbyte|strbyte]](string[, index]) - Returns the internal numeric code of the i-th character of string
: [[API strchar|strchar]](asciiCode[, ...]) - Returns a string with length equal to number of arguments, with each character assigned the internal code for that argument.
: [[API strfind|strfind]](string, pattern[, initpos[, plain]]) - Look for match of pattern in string, optionally from specific location or using plain substring.
: [[API strlen|strlen]](string) - Return length of the string.
: [[API strlower|strlower]](string) - Return string with all upper case changed to lower case.
: [[API strmatch|strmatch]](string, pattern[, initpos]) - Similar to strfind but only returns the matches, not the string positions.
: [[API strrep|strrep]](seed,count) - Return a string which is count copies of seed.
: [[API strrev|strrev]](string) - Reverses a string; alias of string.reverse.
: [[API strsub|strsub]](string, index[, endIndex]) - Return a substring of string starting at index
: [[API strupper|strupper]](string) - Return string with all lower case changed to upper case.
: [[API tonumber|tonumber]](arg[, base]) - Return a number if arg can be converted to number. Optional argument specifies the base to interpret the numeral. Bases other than 10 accept only unsigned integers.
: [[API tostring|tostring]](arg) - Convert arg to a string.

These are custom string functions available in WoW but not normal Lua.
: [[API strlenutf8|strlenutf8]](string) - returns the number of characters in a UTF-8 encoded string.
: [[API strcmputf8i|strcmputf8i]](string,string) - string comparison accounting for UTF-8 chars, returning C style 0, 0<, 0>.
: [[API strtrim|strtrim]](string[, chars]) - Trim leading and trailing spaces or the characters passed to chars from string.
: [[API strsplit|strsplit]](delimiter, string) - Return a list of substrings separated by occurrences of the delimiter.
: [[API strjoin|strjoin]](delimiter, string, string[, ...]) - Join string arguments into a single string, separated by delimiter.
: [[API strconcat|strconcat]](...) - Returns a concatenation of all number/string arguments passed.
: [[API tostringall|tostringall]](...) - Converts all arguments to strings and returns them in the same order that they were passed.
