Wilfred Hughes f26ca24df7 Discard '\n' nodes in C and C++ 
These are from the preprocessor grammar rules, but they're not useful
for difftastic.

Wilfred Hughes 4647112e93 Define a highlighting file for Clojure 
This isn't provided upstream, and the parse tree doesn't have a lot of
information, but we can at least handle string literals and keywords.

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.

Wilfred Hughes 6d58247465 Preserve the outer delimiter when shrinking 
Previously, we'd always discard the outer delimiter if it matched on
both sides. This prevented the tree diff finding optimal diffs.

Fixes #124
 2022-03-16 23:38:05 +07:00
Wilfred Hughes 40d3ccd06c Fix confusion between byte length and codepoint length in styling 
We should split lines based on their codepoint length, so all our
lengths are on codepoint boundaries. We can then safely index by byte position.

All the positions are measured in bytes, not code points. Tweak
function names to make this explicit.

Fixes #149
 2022-03-15 09:50:13 +07:00
Wilfred Hughes b2229d66a8 Always display all lines in a hunk 
Previously we were assuming that the first/last line pairs in a hunk
contained the earliest/latest lines on both sides. This isn't true
when there are no common items between the lines.

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

Fixes #133
 2022-03-15 00:11:30 +07:00
Wilfred Hughes c0d1faae63 Keep exploring the graph even when we find matched delimiters 
Previously we'd get tripped up by cases where choosing equal
delimiters would be be considered the same as entering each delimiter
separately, making diffs worse.

Fixes #147

Wilfred Hughes 88ae00bd88 Use depth difference as a heuristic when comparing equal nodes 
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.
 2022-03-08 09:44:55 +07:00
Wilfred Hughes 6f65bbbbb0 Merge branch 'delim_type' 
Introduce a new type EnteredDelimiter that tracks entering/leaving
list nodes. The PopEither and PopBoth cases reflect the choices more
accurately than a 2-tuple of options.

This is a performance hit (slow_before.rs runtime has increased by
49%) but it's important for diff correctness.

 2022-03-05 11:37:10 +07:00
Wilfred Hughes 25433a0c3d Only consider novel trees at the top level 
Helps with #148. On my machine this changes slow_after.rs from 4.4 to
3.4 seconds, but only reduced instruction count from 12.8B to 10.4B.

The one changed case in sample_files/ is more granular and more
readable.
