(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.
Split JSX indentation calculation into several functions
* lisp/progmodes/js.el (js-jsx--contextual-indentation)
(js-jsx--expr-attribute-pos, js-jsx--expr-indentation): Extract logic
from js-jsx--indentation, and improve the logic’s documentation.
(js-jsx--indentation): Simplify by splitting into several
functions (see above) and improve the logic’s documentation.
Indent expressions in JSXAttributes relative to the attribute’s name
* 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.
Fix counting of nested self-closing JSXOpeningElements
* 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.
Indent broken arrow function bodies as an N+1th arg
* 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.
* lisp/files.el (auto-mode-alist): Simply enable
javascript-mode (js-mode) when opening “.jsx” files, since the “.jsx”
file extension will be used as an indicator of JSX syntax by js-mode,
and more code is likely to work in js-mode than js-jsx-mode, and we
probably want to guide users to use js-mode (with js-jsx-syntax)
instead. Code that used to work exclusively in js-jsx-mode (if anyone
ever wrote any) ought to be updated to work in js-mode too when
js-jsx-syntax is set to t.
* lisp/progmodes/js.el (js-jsx-detect-syntax, js-jsx-regexps)
(js-jsx--detect-and-enable, js-jsx--detect-after-change): New
variables and functions for detecting and enabling JSX.
(js-jsx-syntax): Update docstring with respect to the widened scope of
the effects and use of this variable.
(js-syntactic-mode-name, js--update-mode-name)
(js--idly-update-mode-name, js-jsx-enable): New variable and functions
for indicating when JSX is enabled.
(js-mode): Detect and enable JSX. Print all enabled syntaxes after
the mode name whenever Emacs goes idle; this ensures lately-enabled
syntaxes are evident.
(js-jsx-mode): Update mode name for consistency with the state in
which JSX is enabled in js-mode. Update docstring to suggest
alternative means of using JSX without this mode. Going forward, it
may be best to gently guide users away from js-jsx-mode, since a “one
mode per syntax extension” model would not scale well if more syntax
extensions were to be simultaneously supported (e.g. Facebook’s
“Flow”).
