Wilfred Hughes 5c40cd0282 Prefer _1 and _2 naming for test files 
This is less to type, and it's now alphabetical, so e.g.
sample_files/*.kt just works as a test argument.

Wilfred Hughes 38f148df1f Don't flatten error nodes 
As of b9d44ae65f (released in 0.38), difftastic prefers a textual
diff if any parse errors are present. As a result, users have to
opt-in to allowing parse errors. We can now preserve structure to
produce diffs that are more granular, at the slight risk of changes
being missed if parsers discard tokens.

Wilfred Hughes 7caaaf7fcf Handle nested sliders correctly when preferring the outer delimiter 
Previously we didn't check the state of children, which was an
oversight from the original implementation. As a result, we fixed
nested sliders in fewer situations.

Wilfred Hughes 5824322244 Require some common words to do subword highlighting 
This is important when comparing short string literals. This change
has improved several cases in sample_files/ but I've added a new
example that made the previous unwanted behaviour much more obvious.

Wilfred Hughes 27f59c0b3a Don't treat - as a word constituent

Zhenge Chen ffd49d523a Detect replaced strings 
If a string is replaced with another, apply subword highlighting
similar to how we handle replaced comments.

Wilfred Hughes 87d27c5598 Only split numbers inside comments 
Inside text files, it seems to be better to be conservative and
consider abc123def as one word rather than three.

This is noticeable when looking at changes to the compare.expected
file, which contains hashes. 123c456 and 345c789 don't really have a
`c` in common, so subword highlighting is ugly.

Wilfred Hughes c07e640b24 Remove contiguous penalty 
The contiguous penalty was an attempt to fix the slider problem:

// Old
A B
C D

// New
A B
A B
C D

// Unwanted diff
A +B+
+A+ B
C D

However, it doesn't make sense for Dijkstra, which is stateless. The
best route from vertex X is independent of how we got to vertex X.

This worked by dumb luck: in some circumstances we terminate early
rather than fully executing Dijkstra's algorithm. This cost tweak
improved results on a few test files. However, the post-processing
slider logic is a proper, general solution. This was added much later.

There's no reason to keep the contiguous penalty now. It's confusing,
and makes adding new edge costs with consistent 'X costs more than Y'
behaviours more difficult.

Performance is essentially neutral: a small decrease in
typing_before.ml, a small increase in slow_before.rs.
 2023-07-06 08:37:02 +07:00
Wilfred Hughes 43c24047b4 Don't track contiguous status on novel delimiter edges 
This is harder to reason about, and
2e6666041f did not include a motivating
test case.

Removing contiguous status is a minor perf improvement (2% reduction
in instructions), makes the code simpler, and does not significantly
affect diffing results.

Of the two sample files that have changed, the erlang_before.erl file
has improved and nest_before.rs is neutral.

Wilfred Hughes c405b58327 Fix cost for ReplacedComment 
This needs to be 2x novel nodes, or we prefer it far too often.
 2023-07-02 23:12:31 +07:00
Wilfred Hughes 3730580ca3 Improve word splitting heuristics 
This is particularly noticeable when diffing comments with timestamps
2000-12-31T23:59:59 where we don't want 31T23 to be a single word.
 2023-06-29 08:33:30 +07:00
Wilfred Hughes 8b842387a1 Don't clean trailing newline before diffing 
Difftastic should take the user's input as-is, or it risks performing
an incorrect diff in both textual and syntactic diffing.
