Wilfred Hughes 82890923cd Track entering/leaving parents explicitly 
This produces significantly better diffs, and fixes some cases that
were outright wrong before.

Fixes #30
 2022-02-20 12:43:52 +07:00
Wilfred Hughes 3c1c5649f4 Ensure --color is still respected 
This was broken in the port to owo_colors. owo_colors does not have a
global override: the override function only affects if_supports_color.
 2022-02-13 16:54:57 +07:00
Wilfred Hughes 6004855206 Port to owo_colors 
This library is faster and actively maintained.

Closes #107

Fixes #82
 2022-02-06 16:38:55 +07:00
Wilfred Hughes 0eba3ecabe Update to the latest tree-sitter version 
This is also a minor performance improvement (e.g. saves 1.3% time on
typing_old/new.ml or 3% on elisp_before/after.el).

Wilfred Hughes b270156e48 Update tree-sitter version 
This is a small perf win (30ms runtime on my machine) due to faster
tree_sitter::Query creation.

Wilfred Hughes 667a42d57b Downgrade to tree-sitter 0.20.0 
0.20.1 has a performance regression, which seems to particularly
affect Elixir parsing:

Wilfred Hughes cb900c3463 Revert to term_size 
Git invokes difftastic and then pipes stdout to less, but stderr still
goes to the terminal. term_size queries both stdout and stderr, so it
can still find the terminal width in this situation.

Previously, we'd always use a width of 80 when invoked by git.

terminal_size discussion:
https://github.com/eminence/terminal-size/issues/23

term_size does claim to support Windows, and #71 was not fixed by
changing libraries, so this seems reasonable.
 2021-12-19 12:48:52 +07:00
Wilfred Hughes 6f1baae23e Prefer terminal_width crate so we support more platforms 
term_width is unmaintained and does not support Windows.

Fixes #71

Wilfred Hughes 86724658c0 Update radix-heap version 
This avoids us depending on an old version of ordered_float, which has
a security advisory: https://rustsec.org/advisories/RUSTSEC-2020-0082

It also slightly reduces the number of dependencies of difftastic.

Wilfred Hughes c92007e5b3 Remove criterion 
I've found the numbers pretty noisy on my laptop, and `perf stat` is a
nice way of testing full size files for performance.

Wilfred Hughes 6222987872 Move to mimalloc 
This produces a small (~10% less runtime) improvement on larger files,
as difftastic spends a lot of time allocating.
