Another silly bug...

Silly bug due to forgetting to change a line of code.
2018-01-01 03:20:10 -08:00
2591aef6d4
Simplified the screen buffer writing.
...
Turns out the main reason it was so slow was because stdout isn't
buffered in Rust by default. That actually makes a lot of sense,
but I'd forgotten.
Wrapping it in a BufWriter solves the performance issues much more
gracefully.

Using a smallstring implementation inside the screen buffer.
...
This keeps things contiguous in memory in the common case.
2017-12-31 20:05:00 -08:00
0a309fab1a
Made the screen buffer implemention way faster.
...
It's in a pretty good place now, I think. Although its memory
usage could be improved with a small string type.

At the moment, it's brain-dead and really slow.

Fixed silly drawing bug.

The cursor wasn't displaying if it was on the end of a line.

More fixing.
2017-12-30 23:47:05 -08:00
9c302620e9
Updating to use the new Ropey.
...
This is mainly just for kicks and giggles, since it really won't
work quite properly anyway, due to the lack of grapheme indexing.
The next real thing is to... well, start from scratch.
2017-12-30 23:10:56 -08:00

Was causing the view to move unecessarily when the cursor is at the end of
the buffer.

c532b10f22
Fixed bug in Editor::move_view_to_cursor()
...
It thought it was one line shorter than it actually was.
2015-02-22 20:30:33 -08:00
c348f252bb
Fixed bug in buffer drawing code.
...
It was causing the entire last line to be re-scanned to find the
cursor drawing position if the cursor was at the end of the buffer.
This was both slow and resulted in an incorrect position, since
all the rest of the drawing assumes line blocks.
2015-02-22 20:24:19 -08:00
ae26c5f873
Fixed bugs in LineFormatter that was causing weird cursor nav behavior.
...
They were two pretty much identical bugs in both index_offset_vertical_v2d()
and index_set_horizontal_v2d(). Neither method was checking for slipping
off the end of a line block.
2015-02-22 20:09:18 -08:00
1b3acfd29f
Fixed bug in LineFormatter::index_offset_vertical_v2d()

The bug was causing very incorrect behavior when a single line was long
enough to be split into multiple blocks.
2015-02-22 19:30:13 -08:00
9c462ee332
Finished converting codebase back to plain Rope's.

Forgot to set rope leaf size back to something reasonable.
2015-02-21 13:18:28 -08:00

Implemented efficient Rope splitting.
...
Rope::split() should now run in O(log N) time instead of O(N).
2015-02-21 13:12:26 -08:00

Added benchmarks for Rope::append() and Rope::split().
2015-02-21 11:44:32 -08:00

Improved Rope's text insertion performance for large insertion strings.
2015-02-21 11:16:21 -08:00

Even further improved balance unit tests.

Now the ropes are directly checked for adhering to the AVL balance
invariants.
2015-02-19 23:39:24 -08:00

Significantly improved Rope::rebalance() unit tests.
...
Now they directly run rebalance() on hand-constructed trees that test
various situations.
2015-02-19 23:23:36 -08:00
fe0a7e48ca
Fixed bug in Rope::new_from_str().
...
The stragglers appended at the end were being appended at the top of
the tree, making it very unbalanced. Using proper appending now.
2015-02-19 22:52:21 -08:00

Fixed bug in Rope::rebalance(). Stats weren't updated after rebalance.

Ropes can now generate graphviz of their tree. Useful for debugging.
2015-02-19 22:39:57 -08:00

Improved Rope::append()
...
Append no longer depends on a performant rebalance() operation in any
cases. Append is guaranteed O(log N) now.
2015-02-18 23:41:28 -08:00
d95161b88f
Improved Rope::rebalance() to actually rebalance properly in non-AVL cases.
...
The prior version worked fine for the typical single insertion/removal
cases. But when larger imbalances happened due to bulk insertion or
removal it wouldn't work correctly.
The new improved version works on any tree whose children are themselves
balanced, even if they are extremely different heights when compared to
each other. It works in O(log N) time.
2015-02-18 23:11:10 -08:00
535f219c41
Improved algorithm of Rope::append()
...
It doesn't use an intermediate conversion to a string anymore, and should
execute in O(log N) as long as the right-hand rope is equal length or
smaller than the left.
It may also be O(log N) for the left-hand rope being smaller, but that
depends on whether the rebalance code executes in O(log N) time when
the left and right hand side are individually balanced. I haven't
analysed it yet, so dunno.
2015-02-17 23:10:38 -08:00

Fixed some bugs in the display code.

Everything seems to display correctly now.
2015-02-16 22:46:38 -08:00
311f8aca67
First attempt at making display code really take advantage of long line support.
...
It's not quite working right, but it does at least prevent performance
degradation.
2015-02-16 22:29:41 -08:00
86f3ada8ea
Small tweak to indentation style auto-detection.
...
Very slightly favor larger indentations, instead of very slight favor
smaller indentations. This is more likely to do the right thing on
very small files.

a1d636a4d8
WIP: handling extremely long lines with good performance.
...
The formatters now work on grapheme iterators instead of directly on
lines, which frees up the LineFormatter to break up long lines into
smaller blocks of text. This is partially taken advantage of right
now in various parts of the code, but more work is still needed to
get it both working properly and fast.
2015-02-15 22:41:11 -08:00

In preparation for much more major speed-ups with long lines.

Improved file load times.

There was a regression after switching to ropes. Now it's pretty much
back to pre-rope load times.
2015-02-15 20:15:19 -08:00
de58f01b2f
Added some benchmarks for Rope, and improved new_from_str() for Rope.
...
The new new_from_str() uses an algorithm that should be linear time
complexity compared to the length of the string.
2015-02-15 19:42:07 -08:00
e1c9a6955d
Lines now internally use ropes to store their text.
...
The rope uses a large leaf-node text length, so in the vast majority of
cases this ends up being the same as directly storing the string data.
But in the case that the line becomes extremely long, this will allow
for reasonable performance
2015-02-15 14:56:56 -08:00
a89e505fb0
Beginnings of a Rope data structure for strings.

This will be used to hold the text of an individual line, for better

Line numbers are now displayed in left-hand gutter.

Added rust-encoding as a dependency, in prep for text encoding support.

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

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.
