Wilfred Hughes 28c3b0ef5d Tweak line number styling to make it more distinct from content

Yuya Nishihara 84f0b25fb6 Add support for QML 
QML is a UI language, and its syntax is basically JSON-like structure
+ JavaScript. The tree-sitter parser is named after the upstream grammar
file qmljs.g, but the canonical language name is QML. So I choose Qml as
the Language enum.

Wilfred Hughes a04f867557 Fix terminal width detection 
This was previously fixed in
cb900c3463 (see commit message), but
broken in #341.

Instead, use both term_size and terminal_size, to maximise our chances
that we can detect the width. Also comment the code with the relevant
terminal_size issue.

Wilfred Hughes a247218811 Set +whole-archive on C/C++ libraries 
This fixes the build for Rust 1.61+ on some machines. I can reliably
reproduce this locally, but CI does not exhibit this issue (I'm not
sure why).

The Rust compatibility notes document this change:
https://github.com/rust-lang/rust/blob/1.61.0/RELEASES.md#compatibility-notes

and eventually this will be supported by cc:
https://github.com/rust-lang/cc-rs/pull/671

Wilfred Hughes c957818514 Explore two graph nodes for each parenthesis position 
This produces substantially better diff results, and fixes the 'last
item in the list shown as changed' problem.

This can produce slower diffing. typing_before.ml takes 10% more
instructions and slow_before.rs takes 110% more instructions.

This removes the need to special-case Perl, and is necessary for

marked as 'extra').

 2022-08-02 09:15:11 +07:00
Wilfred Hughes bc283341f3 Use unique subtrees shared between LHS/RHS to determine similar lists 
This makes the 'lists are sufficiently similar' heuristic more
aggressive. Previously we'd look for lists with common start or end
children and the same delimiters.

This worked badly for cases like:

LHS: (novel-lhs (a b c d e))
RHS: (novel-rhs (a b c d e))

Instead, look for sublists that are unique on both sides and occur on
both the LHS and RHS root being considered. This allows us to match up
many more cases.

Consider lists to be sufficiently similar exclusiely using this
(surprisingly effective) heuristic, and don't consider outer
delimiters.

This substantially improves performance in many cases, particularly
for files that are fairly flat (many toplevel lists with little
nesting).

Wilfred Hughes 38c6718c86 Improve handling of /dev/null paths when there are two CLI argsuments 
When git calls us, we always know the file name. If we're called with
two arguments and one is /dev/null, use the other for language
detection and display.

to make this clearer, and add a test.

Wilfred Hughes e38d14a144 Prefer aligning blank lines in display 
After we've aligned lines based on diff results, we have intermediate
lines that we need to align somehow. Previously, we'd just take them
in order, aligning the first on the LHS with the first on the RHS and
so on.

If the intermediate lines start or end with a sequence of blank lines,
prefer aligning the blank lines. If we have both, arbitrarily choose
the ending blank lines.

This has produced better results in many of the sample files, although
in the case of slow_before.rs we've just changed from a leading blank
line alignment to a trailing blank line alignment.

Previously we were assuming that the first/last line pairs in a hunk

This fixes some display issues in load_before/after.js, but include a
new integration test that is smaller and easier to eyeball.

Wilfred Hughes afb1b369f4 Switch to wu-diff for textual diffing 
In #153 a user reported difftastic never terminated on a 140,000
file. This was due to the diff crate using a very large amount of time
and memory.

The diff crate does not use Myers' algorithm, which has a
divide-and-conquer approach using snakes:

https://blog.jcoglan.com/2017/03/22/myers-diff-in-linear-space-theory/

wu-diff does implement Myer's algorithm and performs much better on
these large files.

This reverts commit 7544874a55. It turns
out there are cases where this is still necessary (see new sample
file). It's also performance neutral.

This bug became more obvious with the recent 'skip unchanged'
optimisations. The optimisation changed the number of preceeding nodes and
exposed this bug more often.

49%) but it's important for diff correctness.

Wilfred Hughes 4287594cda Don't consider other paths when UnchangedNode is available 
This substantially decreases the number of edges in our graphs,
especially when few nodes have changed. Diffing slow_before.rs with
slow_after.rs now takes half the time on my machine.

This makes diffing slightly greedier, so there may exist cases where
diffs are slightly worse. Comparing AXAB with AB is arguably nicer
as (+AX)AB rather than A(+XA)B. However, all the tests still pass,
and it's a huge perf win.

Wilfred Hughes 98ca8ea106 Ensure that single-item tree-sitter lists are difftastic lists 
This is important when executing tree-sitter queries, as highlighting
queries tend to target leaf nodes. Flattening the tree loses that.

This may also lead to more accurate diffing logic in some examples,
but I haven't found any obvious cases.

Wilfred Hughes 4e09fd0507 Match delimiters when converting from tree-sitter to syntax 
Previously, we only handled simple cases like `(x)` where the first
and last token were the delimiter tokens. We now allow arbitrary
tokens before and after the delimiter, and wrap them in an additional
list.

This was more common in the C family parsers, but it's a general
problem. It also helps with robustness of JSX/TSX delimiter parsing of
`<`, where we now require a close `>` at the same level.
