Fixes zsh-users/zsh-syntax-highlighting#262. Currently, 'make quiet-test' uses Perl. However, since it is considered a development tool rather than a user-facing tool, users and downstream packages needn't install Perl. Furthermore, even this dev-only dependency may be dropped in the future. The only difference between tests/tap-filter here and the one in the issue is using a `cat` subshell v. using 'undef $/; <STDIN>'. |

zsh-syntax-highlighting / tests
Utility scripts for testing zsh-syntax-highlighting highlighters.
The tests harness expects the highlighter directory to contain a test-data
directory with test data files.
See the main highlighter for examples.
Each test should define the array parameter $expected_region_highlight.
The value of that parameter is a list of strings of the form "$i $j $style".
or "$i $j $style $todo".
Each string specifies the highlighting that $BUFFER[$i,$j] should have;
that is, $i and $j specify a range, 1-indexed, inclusive of both endpoints.
If $todo exists, the test point is marked as TODO (the failure of that test
point will not fail the test), and $todo is used as the explanation.
Note: $region_highlight uses the same "$i $j $style" syntax but
interprets the indexes differently.
Isolation: Each test is run in a separate subshell, so any variables,
aliases, functions, etc., it defines will be visible to the tested code (that
computes $region_highlight), but will not affect subsequent tests. The
current working directory of tests is set to a newly-created empty directory,
which is automatically cleaned up after the test exits.
Highlighting test
test-highlighting.zsh tests the correctness of
the highlighting. Usage:
zsh test-highlighting.zsh <HIGHLIGHTER NAME>
All tests may be run with
make test
which will run all highlighting tests and report results in TAP format.
By default, the results of all tests will be printed; to show only "interesting"
results (tests that failed but were expected to succeed, or vice-versa), run
make quiet-test (or make test QUIET=y).
Performance test
test-perfs.zsh measures the time spent doing the
highlighting. Usage:
zsh test-perfs.zsh <HIGHLIGHTER NAME>
All tests may be run with
make perf
