On the test case, the behaviour was as follows:
+highlighters/main/main-highlighter.zsh:733> _zsh_highlight_main_highlighter__try_expand_parameter '$1'
+highlighters/main/main-highlighter.zsh:432> local arg='$1'
+highlighters/main/main-highlighter.zsh:433> unset reply
+highlighters/main/main-highlighter.zsh:439> local -a match mbegin mend
+highlighters/main/main-highlighter.zsh:440> local MATCH
+highlighters/main/main-highlighter.zsh:440> integer MBEGIN MEND
+highlighters/main/main-highlighter.zsh:441> local parameter_name
+highlighters/main/main-highlighter.zsh:442> local -a words
+highlighters/main/main-highlighter.zsh:443> [[ '$' != \$ ]]
+highlighters/main/main-highlighter.zsh:446> [[ 1 == { ]]
+highlighters/main/main-highlighter.zsh:449> parameter_name=1
+highlighters/main/main-highlighter.zsh:451> [[ none == none ]]
+highlighters/main/main-highlighter.zsh:451> zmodload -e zsh/parameter
+highlighters/main/main-highlighter.zsh:452> [[ ${parameter_name} -regex-match ^${~parameter_name_pattern}$ ]]
+highlighters/main/main-highlighter.zsh:453> [[ '' != *special* ]]
+highlighters/main/main-highlighter.zsh:456> case array-special (*array*|*assoc*)
+highlighters/main/main-highlighter.zsh:458> words=( '$1' )
+highlighters/main/main-highlighter.zsh:469> reply=( '$1' )
There are two problems here:
- In terms of _zsh_highlight_main_highlighter__try_expand_parameter's
pre- and postconditions, the expansion of the word «$1» (line 733)
included that same word (line 469).
That happened because word-to-be-expanded is passed to
_zsh_highlight_main_highlighter__try_expand_parameter as its first
positional parameter, and in this case the word happened to be «$1».
- Furthermore, the exclusion of special parameters (line 453) false
negatived. That happened because $parameter_name_pattern explicitly
allows positional parameters, but ${parameters[(e)1]} expands to
nothing. This will be fixed in the next commit.
Not a regression from 0.7.1.
Before this commit, if the value didn't begin with a dollar sign,
_zsh_highlight_main_highlighter__try_expand_parameter() would return 1
by accident.¹ Tweak the input validation to make this behaviour
explicit. No functional change.
¹ Specifically, it would return 1 because ${parameter_name}'s value
would be the empty string and ${parameter_name_pattern} wouldn't match
that.
Fixes#202.
Test expectations are updated. For example, BUFFER='/bin' is now
highlighted as path_prefix because it's a prefix of '/bin/sh' which
would be valid. However, BUFFER='/bin;' is now properly highlighted
as an error (unless AUTO_CD is set).
The escaped caret was taken for a negated character class. This caused test-data/arith1.zsh
to XPass: the arithmetic expansion was consumed by the 'while' loop.
This is not perfect: we don't try to detect cases such as «$((ls); (ls))»,
which look like arithmetic expansions but are in fact command substitutions.
Fixes part of #607.
Introduces #704.
* commit 'b1f36d9c5f45b879fbd2f64195167a60d9f3cb9e':
'main': Add a comment.
'main': Fix the $CDPATH from the previous commit.
'main': Add a test for a $CDPATH bug.
* danielsh/tests-skip-cardinality-v1:
tests: Minor documentation readability tweak
Add a test for issue #641.5, using the infrastructure added in the previous commits.
tests: Skip cardinality tests whenever any test point is expected to fail.
tests: Make $expected_mismatch skip the cardinality check, rather than consider it an expected failure.
tests: Include the name of the 'cardinality check' test point in the output
Before this commit, the command word was highlighted as "unknown-token"
not because alias loops are invalid, as a comment incorrectly claimed,
but because the command word «a» resolved to a «b» that was ineligible
for being expanded as an alias, and there was no function/builtin/etc.
called "b".
Add a function "b" to demonstrate that alias loops are valid. I've also
filed issue #695 about the overloading of "unknown-token".
Fixes#501.
Fixes#616 (the original form; not the form in
test-data/alias-comment1.zsh which is now considered o be #677 (see
previous commit for details)).
Fixes a latent bug in test-data/always2.zsh.
No user-visible effect, and therefore, no changelog entry.
In «a="b=c"; $a», the '=' sign in the expansion of $a is not active.
Therefore, prevent the expansion of $a from being considered an
assignment. Update test expectations accordingly.
Before the parent commit, they behaved as follows:
ZSH_PATCHLEVEL=debian/5.7.1-1
# parameter-value-contains-command-position1
1..2
ok 1 - [1,7] «$foobar» - # TODO "issue #670"
not ok 2 - have 1 expectations and 6 region_highlight entries: «expected_region_highlight=( '1 7 assign "issue ♯670"' )» «region_highlight=( '0 7 assign' '2 7 default' '2 7 command-substitution-unquoted'
zsh-syntax-highlighting: BUG: _zsh_highlight_highlighter_main_paint: start(2) >= end(2)
Bail out! On './highlighters/main/test-data/parameter-value-contains-command-position2.zsh': output on stderr
# parameter-value-contains-command-position2
1..2
ok 1 - [1,2] «$y» - # TODO "issue #670"
ok 2 - cardinality check
Due to the the "BUG:" and "Bail out!" on the first one, they could not
be added as XFAIL tests before the parent commit.
We cannot now for sure whether the flag is misspelled or simply unknown to us,
so err on the side of caution. This fixes an unreleased regression. Fixes#658.
Issue #641 was originally filed about this problem, but is left open to track
further enhancements.
