Make the indentation of the code right after an open paren/brace
use the same rule as already used to indent the corresponding
matching paren/brace.
* lisp/progmodes/perl-mode.el (perl-calculate-indent):
Use `perl-indent-new-calculate`s "virtual" indentation instead of
approximating it with `current-indentation`.
* lisp/progmodes/sh-script.el (sh-font-lock-paren): Also recognize
`FOO)` after `{`.
(sh-smie-sh-rules): Make `for` rule apply to `case FOO { ...}` as well.
* test/manual/indent/shell.sh: Add new test case.
* lisp/progmodes/sh-script.el (sh-font-lock-paren)
(sh-smie-sh-grammar, sh-smie-sh-rules, sh-smie-rc-grammar):
Support case branches ending with ";|", per Zsh. (Bug#60833)
* test/manual/indent/shell.sh (bar): Add ";|".
(perl-syntax-propertize-function): Don't put a syntax-property
on regexp-op delimiters if they're already handled correctly
by the normal syntax tables.
(perl-syntax-propertize-special-constructs): Mark the middle
quote of s'foo'bar' as punctuation.
* test/manual/indent/perl.perl: Add new test cases.
(tcl--word-delimiters): New const.
(tcl--syntax-of-quote): New function.
(tcl-syntax-propertize-function): Use them.
(tcl-mode): Enable `syntax-propertize-multiline`.
* test/manual/indent/tcl.tcl: New file.
(calculate-lisp-indent): To distinguish code and data when indenting,
introduce the convention that a space between an open paren and
a symbol indicate that this should be indented as a simple data list.
* lisp/textmodes/css-mode.el (css-nmchar-re): Allow underscores in
variable names (and in identifiers in general).
* test/manual/indent/css-mode.css: Add some examples of variable names
with underscores in them.
* test/manual/indent/less-css-mode.less: Add some examples of variable
names with underscores in them.
* test/manual/indent/scss-mode.scss: Add some examples of variable
names with underscores in them.
* lisp/progmodes/js.el (js-jsx-align->-with-<): New variable for users
to control one opinionated aspect of JSX indentation. It defaults to
the style seen in the React docs, which many users expected as the
“correct” indentation. Still, the old SGML-style of indentation could
be desirable too, especially since it was the old default. This
ensures users have a way of getting back the old behavior.
(js-jsx--contextual-indentation): Respect js-jsx-align->-with-<.
* test/manual/indent/jsx-align-gt-with-lt.jsx: New test for
js-jsx-align->-with-<.
* lisp/progmodes/js.el (js-jsx-indent-level): New variable for users
to set JSX indentation differently than JS, like before.
(js-jsx--contextual-indentation): Respect js-jsx-indent-level when
it’s set.
* test/manual/indent/jsx-indent-level.jsx: New test for
js-jsx-indent-level.
* lisp/progmodes/js.el (js--name-start-re): Generally allow
identifiers to begin with non-ASCII letters. This is of particular
importance to JSX parsing.
* test/manual/indent/jsx-unclosed-2.jsx: Add test to ensure non-ASCII
characters are parsed properly.
* lisp/progmodes/js.el (js--name-start-chars): Remove, adding these
chars back to js--name-start-re.
(js--name-start-re): Add chars back from js--name-start-chars.
(js-jsx--tag-start-re): Improve regexp to capture the tag name (so it
can be disambiguated from a unary keyword), to match newlines (which
are common in this spot), and to require at least one whitespace
character before the attribute name.
(js-jsx--matched-tag-type): Ensure the “tag name” isn’t possibly a
unary keyword.
(js-jsx--self-closing-re, js-jsx--matching-close-tag-pos): Allow
whitespace around “<” and “>”.
* test/manual/indent/jsx-unclosed-2.jsx: Add tests for unary keyword
and whitespace parsing.
This function’s performance was having a noticeable impact when
editing large JSX structures. Improve its performance
slightly (elapsed time will be cut in half according to ELP).
* lisp/progmodes/js.el (js-jsx--tag-re): Remove.
(js-jsx--matched-tag-type): Simplify implementation with respect to
the new implementation of js-jsx--matching-close-tag-pos.
(js-jsx--self-closing-re): Simplify regexp slightly in sync with a
generally simpler matching algorithm.
(js-jsx--matching-close-tag-pos): Optimize matching algorithm by using
multiple simple regexp searches, rather than one big complex search.
* test/manual/indent/jsx-unclosed-2.jsx: Use the term “inequality” and
add a test for a possible parsing foible.
* lisp/progmodes/js.el (js-jsx--syntax-propertize-tag): Refer to the
beginning of a JSXExpressionContainer’s associated JSXAttribute (so
line numbers can be calculated later).
(js-jsx--text-properties): Also clear the new text property
js-jsx-expr-attribute.
(js-jsx--indenting): Remove.
(js-jsx--indent-col, js-jsx--indent-attribute-line): New variables.
(js-jsx--indentation): Instead of alternating between two separate
column calculations, neither necessarily correct, bind the JSX column
such that the second call to js--proper-indentation can use it as a
base column.
(js--proper-indentation): Use JSX as the base column for some indents
while indenting JSX.
* test/manual/indent/jsx.jsx: Add more tests for expression indents.
* lisp/progmodes/js.el (js-jsx--matching-close-tag-pos): Fix bug where
self-closing JSXOpeningElements might be missed if one was nested
within another.
* test/manual/indent/jsx-self-closing.jsx: Add test for bug concerning
self-closing JSXOpeningElement counting.
* lisp/progmodes/js.el (js--line-terminating-arrow-re): Revise regexp
for use with re-search-backward.
(js--looking-at-broken-arrow-function-p): Remove.
(js--broken-arrow-terminates-line-p): Replacement for
js--looking-at-broken-arrow-function-p. Don’t consider whether an
arrow appears at point (in an arglist); instead, just look for an
arrow that terminates the line.
(js--proper-indentation): Use js--broken-arrow-terminates-line-p.
* test/manual/indent/js.js: Add test for a broken arrow as an N+1th
arg.
* test/manual/indent/js-jsx-quote.js: Renamed to “jsx-quote.jsx”.
* test/manual/indent/js-jsx-unclosed-1.js: Renamed to
“jsx-unclosed-1.jsx”.
* test/manual/indent/js-jsx-unclosed-2.js: Renamed to
“jsx-unclosed-2.jsx”.
* test/manual/indent/js-jsx.js: Renamed to “jsx.jsx”.
* test/manual/indent/jsx-quote.jsx: Renamed from “js-jsx-quote.js”.
* test/manual/indent/jsx-unclosed-1.jsx: Renamed from
“js-jsx-unclosed-1.js”.
* test/manual/indent/jsx-unclosed-2.jsx: Renamed from
“js-jsx-unclosed-2.js”.
* test/manual/indent/jsx.jsx: Renamed from “js-jsx.js”.
* lisp/progmodes/js.el (js-jsx--attribute-name-re): New variable.
(js-jsx--syntax-propertize-tag): Allow “-” in JSXAttribute names. Fix
“out of range” error when typing at the end of a buffer. Fix/improve
future propertization of unfinished JSXBoundaryElements.
* test/manual/indent/js-jsx-unclosed-2.js: Add tests for allowed
characters in JSX.
