Moved from termion to crossterm for terminal handling.
...
This should (hopefully) make led work on Windows now. Although
I don't have a Windows box to test on.
This also fixes a bug where control codes were ocassionally split
on input, resulting in e.g. a pg-down resulting in control
characters inserted into the buffer.

Some nice performance improvements with a simple optimization.
...
We're now very close to being back to the performance levels
we were at before the new Ropey without built-in grapheme
support.
2018-07-05 18:43:17 -07:00

Another small optimization.
2018-07-05 05:01:57 -07:00
b19997b975
Did some basic optimizations that made things fast again. Yay!
...
The basis for the optimizations were some less basic changes made
in Ropey.
2018-07-05 04:41:58 -07:00

066f0b03cf
Indentation detection can now detect arbitrary space counts.
...
It was using a fixed-size array before, but now is using a
HashMap. This is technically slower, but it's such a negligible
part of the runtime to begin with that it doesn't matter.
2018-01-01 15:01:19 -08:00
020827806b
Use iterator methods to make auto-detect code a little cleaner.
...
Also use chars instead of graphemes for indent detection code.
Graphemes are slower, and don't provide any benefit there.
2018-01-01 14:06:17 -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.
2018-01-01 03:10:32 -08:00

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.

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

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.

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

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.

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

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
