commit 382a508ed21e4f12ace9f8871818e25235e8f05e (HEAD, refs/remotes/origin/master) Author: Jackson Ray Hamilton Date: Wed Apr 10 22:53:34 2019 -0700 Add extra text property to fix issue with js2-mode integration * lisp/progmodes/js.el (js-jsx--put-syntax-table): New function for consistently ensuring smooth js2-mode integration. js2-mode sets syntax-table temporarily while parsing buffers—seemingly to recover from parsing interruptions—and then it later clears syntax-table blindly. When integrating with js-mode, this means that unterminated string quotes are re-broken in JSX (i.e., they become strings again, often stringifying large regions of the buffer which should not be strings). We try to treat quotes in JSXText as non-strings by setting syntax-table to a non-“string quote” syntax class, but that stops working if we lose the property. On the js2-mode end, by scanning for this second js-jsx-syntax-table property, we can recover the syntax-table property there. (js-jsx--text-range, js-jsx--syntax-propertize-tag): Use js-jsx--put-syntax-table for above reason. (js-jsx--text-properties): Clear the js-jsx-syntax-table property too. diff --git a/lisp/progmodes/js.el b/lisp/progmodes/js.el index afdc28e53b..a0adaa84ee 100644 --- a/lisp/progmodes/js.el +++ b/lisp/progmodes/js.el @@ -2140,6 +2140,14 @@ JSXElement or a JSXOpeningElement/JSXClosingElement pair." ;; `syntax-propertize-rules' loop so the next JSXBoundaryElement can ;; be parsed, if any, be it an opening or closing one. +(defun js-jsx--put-syntax-table (start end value) + "Set syntax-table text property from START to END as VALUE. +Redundantly set the value to two properties, syntax-table and +js-jsx-syntax-table.
