Split remove_text() into remove_text_before() and remove_text_after().
...
This is useful so that undo knows where to put the cursor.

A simple implementation of move_text.
...
This should probably be replaced by a more efficient implementation in
the future, as this version will be slow and require large allocations
when moving large pieces of text. But let's wait and see if it's a
problem in practice first.

Stub and unit tests for a move_text implementation.
2015-01-11 00:16:59 -08:00

Moved tab_width to Buffer, and misc cleanup related to that.
2015-01-10 23:42:59 -08:00
8b1f1b1e96
Renamed and documented the buffer position conversion functions.
2015-01-10 16:34:28 -08:00
6b5b63dba1
Added full undo/redo functionality.
2015-01-10 12:29:58 -08:00

Organized the code in buffer/mode.rs a bit more nicely.
2015-01-10 12:02:29 -08:00
8fd1659292
Better unit test hygiene, and renamed buffer len() to grapheme_count().
2015-01-10 11:48:20 -08:00
6c659a17dc
Switched undo stack to use a linked list instead of a vector.
...
This makes sure there aren't pathological cases where the user has been
typing for a very long time, and the undo stack needs to change capacity.
2015-01-09 22:40:41 -08:00
b837d488a5
Basic undo functionality.
2015-01-09 22:02:32 -08:00

Updated code to compile with Rust 1.0 alpha.
2015-01-09 18:50:27 -08:00
2785c3821b
Updated code to compile with the most recent Rust nightly.

ff6c763821
Soft tabs and user-settable tab-widths are now supported.
...
Also, indentation style is automatically detected on file load.
2015-01-04 00:09:34 -08:00
0941339906
Basic line-ending detection when opening files.
...
Buffers now store what line-ending type they consider themselves to be,
and the ui uses that when adding new lines while editing.
2015-01-03 15:15:14 -08:00

Fixed some bugs relating to text and cursor printing.

Non-uniform-width characters are now properly handled (modulo bugs).
2015-01-02 15:05:21 -08:00
7099e4d0d3
Sped up file loading and saving.
2015-01-01 13:14:32 -08:00
cb5b79ec9c
Changed editor drawing to use line iterators.
...
This makes the code easier to follow, and will make it easier to
accomodate non-uniform width graphenes later on.

Got basic editing functionality up and running again after the refactor.

Got grapheme iterators and 1d/2d position translation working.
2014-12-31 17:55:20 -08:00

Got remove_text() working.
...
At least, based on the unit tests so far.

WIP refactor: text can now be inserted into empty buffers.
2014-12-30 22:55:23 -08:00
c88ba48b6d
WIP refactor: change text buffer to use the Line struct for storing text.
...
Most of the UI and editor code is either commented out or not included
in the compile right now. This is temporary while I get the basic
text code working again.
2014-12-29 16:17:53 -08:00
370d8a315e
WIP refactor: changing internal text representation to be line-based.
...
This will make some of the internals a little more complex, but should
simplify things on the balance.

Scrolling in the editor by following the cursor now works.

Added a some text manipulation methods, and made backspace work properly.

Basic cursor movement is now working properly.

WIP: building a proper UI for editing a file.

Some things don't quite work properly yet...
