Return the text in a given range.
- Pictures (and other objects) are represented by 0xFFFC.
Return the text in a given range.
- Pictures (and other objects) are stripped form the output.
Return the visible text in a given range.
- Pictures (and other objects) are represented by 0xFFFC.
Return the visible text in a given range.
- Pictures (and other objects) are stripped form the output.
Check if TextIter is within an editable region.
- If no tags that affect editability are attached to the current position def will be returned.
- This function cannot be used to decide whether text can be inserted at TextIter. Use the textIterCanInsert function for this purpose.
Check if new text can be inserted at TextIter.
- Use textBufferInsertInteractive if you want to insert text depending on the current editable status.
Determine if TextIter point to the beginning of a line delimiter.
- Returns False if TextIter points to the n in a rn sequence.
Return number of characters in this line.
- The return value includes delimiters.
Move TextIter forwards.
- Retuns True if the iterator is pointing to a character.
Move TextIter backwards.
- Retuns True if the movement was possible.
Move TextIter forwards by n characters.
- Retuns True if the iterator is pointing to a new character (and False if the iterator points to a picture or has not moved).
Move TextIter backwards by n characters.
- Retuns True if the iterator is pointing to a new character (and False if the iterator points to a picture or has not moved).
Move TextIter forwards.
- Retuns True if the iterator is pointing to a new line (and False if the iterator points to a picture or has not moved).
- If TextIter is on the first line, it will be moved to the beginning of the buffer.
Move TextIter backwards.
- Retuns True if the iterator is pointing to a new line (and False if the iterator points to a picture or has not moved).
- If TextIter is on the first line, it will be moved to the end of the buffer.
Move TextIter forwards by n lines.
- Retuns True if the iterator is pointing to a new line (and False if the iterator points to a picture or has not moved).
- If TextIter is on the first line, it will be moved to the beginning of the buffer.
- n can be negative.
Move TextIter backwards by n lines.
- Retuns True if the iterator is pointing to a new line (and False if the iterator points to a picture or has not moved).
- If TextIter is on the first line, it will be moved to the end of the buffer.
- n can be negative.
Move TextIter forwards by n word ends.
- Retuns True if the iterator is pointing to a new word end.
Move TextIter backwards by n word beginnings.
- Retuns True if the iterator is pointing to a new word start.
Move TextIter forwards to the next word end.
- Retuns True if the iterator has moved to a new word end.
Move TextIter backwards to the next word beginning.
- Retuns True if the iterator has moved to a new word beginning.
Move TextIter forwards to the next cursor position.
Move TextIter backwards to the next cursor position.
Move TextIter forwards by n cursor positions.
- Returns True if TextIter moved and points to a character (not to an object).
Move TextIter backwards by n cursor positions.
- Returns True if TextIter moved and points to a character (not to an object).
Move TextIter forwards by n sentence ends.
- Retuns True if the iterator is pointing to a new sentence end.
Move TextIter backwards by n sentence beginnings.
- Retuns True if the iterator is pointing to a new sentence start.
Move TextIter forwards to the next sentence end.
- Retuns True if the iterator has moved to a new sentence end.
Move TextIter backwards to the next sentence beginning.
- Retuns True if the iterator has moved to a new sentence beginning.
Moves TextIter to the end of the line.
- Returns True if TextIter moved to a new location which is not the buffer end iterator.
Move TextIter forward until a predicate function returns True.
- If pred returns True before limit is reached, the search is stopped and the return value is True.
- If limit is Nothing, the search stops at the end of the buffer.
Move TextIter backward until a predicate function returns True.
- If pred returns True before limit is reached, the search is stopped and the return value is True.
- If limit is Nothing, the search stops at the end of the buffer.
Search forward for a specific string.
- If specified, the last character which is tested against that start of the search pattern will be limit.
- TextSearchFlags may be empty.
- Returns the start and end position of the string found.
Search backward for a specific string.
- If specified, the last character which is tested against that start of the search pattern will be limit.
- TextSearchFlags my be empty.
- Returns the start and end position of the string found.
Compare two TextIter for equality.
- TextIter could be in class Eq and Ord if there is a guarantee that each iterator is copied before it is modified in place. This is done the next abstraction layer.

| :: TextIter | |
| -> IO Bool | returns whether iter can be dereferenced |
Moves iter to the start of the next visible line. Returns True if there was a next line to move to, and False if iter was simply moved to the end of the buffer and is now not dereferenceable, or if iter was already at the end of the buffer.
| |
| :: TextIter | |
| -> IO Bool | returns whether iter moved |
Moves iter to the start of the previous visible line. Returns True if iter could be moved; i.e. if iter was at character offset 0, this function returns False. Therefore if iter was already on line 0, but not at the start of the line, iter is snapped to the start of the line and the function returns True. (Note that this implies that in a loop calling this function, the line number may not change on every iteration, if your first iteration is on line 0.)
| |
| :: TextIter | |
| -> Int | count - number of lines to move forward |
| -> IO Bool | returns whether iter moved and is dereferenceable |
Moves count visible lines forward, if possible (if count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If count is 0, the function does nothing and returns False. If count is negative, moves backward by 0 - count lines.

| :: TextIter | |
| -> Int | count - number of lines to move backward |
| -> IO Bool | returns whether iter moved and is dereferenceable |
Moves count visible lines backward, if possible (if count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If count is 0, the function does nothing and returns False. If count is negative, moves forward by 0 - count lines.
