Beginnings of a Rope data structure for strings.
...
This will be used to hold the text of an individual line, for better
long-line handling.

Basic text buffer drawing is working again.
2015-02-07 00:45:28 -08:00
3ae51f7f7e
Formatters are now primarily factories for iterators.
...
This is a big shift in the formatter API's. It simplifies the
responsibilities of the implementers so that pretty much all they
have to do it implement an iterator. Everything else will be
automatically derived from that. (Or, at least, that's the hope.)
2015-02-06 23:58:19 -08:00
8319033ae5
First step in pulling formatters out of the text buffer.
...
This commit pulls the formatter out of the text buffer and
puts it in the editor instead. However, there is a lot of
commented code utlizing the buffer and formatter that still
needs to be updated.
In short, the editor is pretty non-functional in this commit.
2015-02-06 19:47:52 -08:00
e29777e33c
Improved file loading.
...
File loading is now the responsibility of the Buffer, which allows
it to do some weird internal stuff to make it faster.
Also, using custom code for scanning the text, so all line endings
are handled now, not just LF and CRLF.
2015-02-01 23:17:43 -08:00
4d114162ee
Improved window resizing responsiveness.
...
The reformat code was being run on every resize event,
which chokes on most resizes which end up emitting a lot
of resize events. Now it waits and processes a bunch of
resize events until there aren't any left, and only does
the actual reformat on the last one.
2015-02-01 13:50:47 -08:00
c9d09f6f98
Moved line_ending_type out of Buffer and into Editor.
2015-01-31 15:06:04 -08:00
67e4495d83
Minor tweak to console formatting code.

Made it so that the line-height can be easily changed in one
place, for experimentation.
2015-01-31 13:53:07 -08:00

Fixed nasty bug in reformatting code.

It was not actually reformatting things...
2015-01-31 13:41:41 -08:00

Line wrapping width is now determined by terminal width.
2015-01-31 13:19:14 -08:00

Tweaked code to avoid warnings from latest rustc compiler.
2015-01-29 21:03:56 -08:00
c6cfebdb75
Commented out the GUI modules until I can figure out how to get it working again.
...
The rust SDL2 bindings have changed in a way that makes the lifetimes
very strict. This is probably a good thing from a safety standpoint,
but means I'll likely need to re-architect the GUI drawing code.
For now I'm going to leave that on the back-burner and focus on getting
the console version working.
2015-01-29 20:35:19 -08:00

Misc code cleanup.

Console editor appears to be back up to snuff again!
2015-01-24 21:38:13 -08:00

Console drawing is almost back up to snuff.

Just missing drawing the cursors if it's at the end of the text buffer.
2015-01-24 21:00:30 -08:00
c69ebc240f
WIP: making Buffers so they can be given LineFormatters.
...
A LineFormatter determines how a line of text is visually displayed in
2d space. This allows both the Console and GUI version of the editor
to share the same buffer code whilst still handling the differing ways
in which both handle visual display.
2015-01-24 14:35:49 -08:00

Source Code Pro is now embedded in the executable as the default font.

Cleaned up GUI rendering code a bit.

ea6d1c56d1
A feeble attempt to overcome flickering issues on window resize.
...
It really seems insurmountable at this point. Not sure what SDL is doing
that's causing this. But I'm leaving this code in, because it makes
things a little cleaner and serves as a good example to myself for how
to render to textures.
2015-01-20 21:55:11 -08:00
6c6e8896a1
GUI actually displays the text of the loaded buffer now. Woo hoo!
...
To make this performant, the Font struct caches rendered glyphs as
sdl textures. Without caching, performance is abysmal.
2015-01-19 22:47:43 -08:00

Beginnings of a GUI.
2015-01-18 22:52:35 -08:00
ac784077f0
Split cursor code into separate file.
...
There is now a CursorSet type that handles multiple cursors, and makes
it convenient to maintain the necessary invariants expected by the rest
of the code for multi-cursor editing.
2015-01-18 15:11:49 -08:00
30ad0c2ea4
Added SDL2 and Freetype as dependencies, in preparation for a GUI.

Also wrapped Freetype functionality in a Font struct.

Undo/redo should mark buffer as dirty.
2015-01-11 01:04:24 -08:00
f56d3f0ad4
Split remove_text() into remove_text_before() and remove_text_after().

This is useful so that undo knows where to put the cursor.
2015-01-11 00:59:02 -08:00
dfcf9fc6a5
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.
2015-01-11 00:26:39 -08:00
8a51a796ce
Stub and unit tests for a move_text implementation.

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

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
f760d6078d
Added jump-to-line functionality and fixed some display bugs.

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.
2014-12-31 20:19:12 -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.

e3e2c866b9
We now store character widths in TextBlocks.

the program eating up CPU when idle.

Super simple text editing interface!

No cursor yet, just always appends to the end of the current buffer.
But still!
2014-12-14 21:06:48 -08:00
9c4e11bc9c
Created an iterator for TextBuffers.
...
In the process, I've also changed all of the text interfaces to work in
term of unicode code-points instead of bytes. This ensures that editing
operations never corrupt utf8 data.
2014-12-14 16:43:17 -08:00
