Returns the index (starting at 1) of the first instance of substring in string at index >= startIndex. Returns 0 if substring is not found.
This function will find occurrences that consist of the same Unicode characters as substring, but won't find occurrences that consist of the same Unicode string decomposed into a different number of Unicode characters.
Returns the index (starting at 1) of the last instance of substring in string. Returns 0 if substring is not found.
This function will find occurrences that consist of the same Unicode characters as substring, but won't find occurrences that consist of the same Unicode string decomposed into a different number of Unicode characters.
| VuoList_VuoInteger VuoText_findOccurrences | ( | const VuoText | string, |

Returns a list containing all occurrences of substring in string.
This function will find occurrences that consist of the same Unicode characters as substring, but won't find occurrences that consist of the same Unicode string decomposed into a different number of Unicode characters.

| uint32_t* VuoText_getUtf32Values | ( | const VuoText | text, |

Returns an array of unicode 32 bit decimal values for each character in a string.
If conversion fails, length will be set to 0 null is returned. Otherwise an array is returned and length is set to the size of the array. Caller is responsible for freeing the returned array.
Returns a new string with newText inserted at the startIndex.
startIndex is 1 indexed, not 0. If startIndex is less than 1, newText is inserted at the beginning of string. If startIndex is greater than string length, newText is appended to the ending of string.

| VuoText VuoText_make | ( | const char * | unquotedString | ) |
Creates a VuoText value from an unquoted string (unlike VuoText_makeFromString(), which expects a quoted string).

| VuoText VuoText_makeWithMaxLength | ( | const void * | data, |
| const size_t | maxLength | ||
| ) |
Creates a VuoText value from an untrusted source (one that might not contain a NULL terminator within its memory page).
Use this, for example, to safely handle a string that's part of a network packet.
If data ends with a NULL terminator, this function simply copies it into a new VuoText instance.
If data does not end with a NULL terminator, this function scans up to maxLength bytes in data. If it finds a NULL terminator, it returns text up to and including the NULL terminator. If it doesn't find a NULL terminator, it returns maxLength characters followed by a NULL terminator.
If data is in a multi-byte UTF8 character sequence when maxLength is reached, the sequence will be terminated partway, probably resulting in an invalid UTF8 sequence.

| VuoText * VuoText_split | ( | VuoText | text, |
| VuoText | separator, | ||
| bool | includeEmptyParts, | ||
| size_t * | partsCount | ||
| ) |
Splits text into parts (basically the inverse of VuoText_append()).
Returns the substring of string starting at index startIndex and spanning length Unicode characters.
startIndex is indexed from 1, not 0.
If startIndex is past the end of string, returns the empty string.
If startIndex is before the beginning of string, deducts the number of characters before the beginning from length, and returns characters starting at the beginning of string.
If string has fewer than length characters from startIndex to the end of string, returns all characters from startIndex to the end of string.
Returns a new string consisting of text without the whitespace at the beginning and end.
This function trims ASCII spaces, tabs, and linebreaks, but not other Unicode whitespace characters.
