Release 3.2.0
New features
Added comment toggling, automatic indentation, and tag-closing to nearly all languages. Previously this was only present in markup, markdown, xml, css, jsx, tsx, python and some c-like languages (18e814c)
Added two parameters to the matchBrackets()
extension used to customize which punctuation tokens can be matched together. The extension now searches both the first and last characters in punctuation tokens instead of just the last character. This comes at a slight performance cost, but only testing the last character didn't work for a few languages (64c6041)
Added the ending position of the bracket to the Bracket
type (64c6041)
Changes
The fullEditor()
setup along with its web component have been marked as deprecated. This is because they'll get merged together with the basicEditor()
setup in the next major release (2897736)
The NPM package no longer contains minified JavaScript code (#7) (56907f1)
Improvements
- Improved patterns of multiline tokens in Haml, Pug and Sass grammars (fb025d9, 9e7f0f2)
- Added bracket comments to CMake (c3c7614)
- Small refactors to many Prism grammars (0cebe12)
- Whitespace is no longer required between attributes in JSX tags (0a1d28a)
- Improved escaping of braces in XQuery using
{{
(4672340)
Better templating (7943a7c)
The placeholders for the templating are now simply whitespace instead of looking like ___PH0___
. This has multiple advantages:
- It works with all grammars. Previously, grammars that could split the placeholders into multiple tokens couldn't be used as host grammars.
- It's less complex, requiring significantly less code.
- It sometimes leads to better highlighting.
Additionally, recursion was used to insert multiple placeholders into the same string. Highlighting '<??>'.repeat(5000)
with PHP would therefore lead to a stack overflow. Rewriting this to a loop fixes the potential stack overflows and improves performance. In most cases the performance increase is in the ballpark of 10-20%, but in best-case scenarios it can be multiple times faster.
Bug fixes
- Fixed selection often being incorrect after an undo (fc3c678, e4382f5)
- JSX tags with a block comment at the end like
<div /* */>
no longer behave like self-closing tags (0a1d28a) - JSX fragments now automatically close when typing
- HTML tags such as
<a href=foo/>
no longer behave like self-closing tags (0a1d28a) - Self closing tags are no longer case sensitive, so for example
<INPUT>
would be self-closing in HTML (0a1d28a)
Release 3.1.1
Fix tooltips that broke in version 3.1.0 (8eb668f)
Release 3.1.0
New features
History extension
Previously, the browser's native undo/redo was used. While this often worked well enough, it has its limitations. In Chrome and Safari, all form elements share the same undo stack, and in Firefox, hiding an element with display: none
would clear its undo history. The new history extension has none of these issues. You can even transfer the history from an editor to another, but not without breaking the old editor.
The extension is tiny. Adding it to the demo website, only increases its JS bundle by 0.35kB gzipped.
The history extension has been added to the basic setup and the full setup. The extension can be accessed from PrismEditor.extensions
.
// Here's how to import the extension
import { editHistory } from "prism-code-editor/commands"
New theme
Prism's Tomorrow Night theme has been implemented. It's on the demo website if you want to try it.
Note: I forgot to add this file to the package. This was fixed in 3.1.2
import "prism-code-editor/themes/prism-tomorrow.css"
Improvements
- Significantly increased performance of the
getClosestToken()
utility, especially for long lines. This was achieved by using aTreeWalker
for the searching instead of usingquerySelector()
coupled withRange.toString()
to find the position of the tokens. The performance increase can be anywhere from a few times faster for short lines to a greater than 100x improvement for lines 1000s of characters long. Not sure why you'd view minified code in an editor, but that will perform much better now (9f8ebe6) - Decreased gzipped size of all Prism languages by more than 10kB (5%) through refactoring and optimization.
- An
input
event on the textarea now always updates the editor even if its value didn't change (7a3ddef)
Fixes
- Added
.js
extensions to most imports. The type declarations now work properly with amoduleResolution
ofNodeNext
orNode16
(b94978b) - Added
type="button"
to the copy button and all buttons in the search widget. If you had an editor inside a form, these buttons would previously submit the form when clicked. This is no longer the case (8ea416b) - Fixed potential empty matches that could lead to buggy highlighting in multiple languages (b28da8d)
- The
getLanguage()
utility now supports languages with hyphens in their name (d214971) - Changed the default tab size of the web components from 0 to 2 spaces. This wasn't a big issue since 0 would internally be replaced with 2 (e2ad6e5)
- Fixed alignment issue with the
highlightSelectionMatches()
extension in RTL mode (741bc85) - Fixed incorrect highlighting of capitalized generic functions in the TSX language (bf85599)
- Added a
language-jsx
alias to spread tokens inside JSX tags (bf85599)
Search widget improvments
- Selection change handlers no longer run with the incorrect selection after calling the
insertText()
utility if the search widget is open (7a3ddef) - Selection matches are no longer highlighted after replacing a match with the search widget (7a3ddef)
- The keyboard shortcuts for the 4 toggle buttons now uses
keyCode
instead ofcode
on Mac. This will work better with non-QWERTY keyboards on Mac (7a3ddef)
Release 3.0.1
- Fenced code blocks with more than three backticks are now supported in markdown (e40eaa7)
- Fixed empty script/style tags potentially breaking the highlighting of css/js inside later script/style tags (b84f011)
- The bracket level no longer gets reset back to zero when entering a nested token, so the rainbow brackets now work as expected again (0f304a2)
- The search match selected while typing in the search widget is now the match closest to where the cursor was last time the editor was focused. This means the editor's cursor will jump less around while searching (eb00bbc)
Release 3.0.0
Breaking changes
The modified Prism instance has been significantly changed and more of Prism v2's features have been added, most notably custom tokenizers. Below is a list of most changes:
- Everything Prism related is now exported from its own entry point
prism-code-editor/prism
- Prism grammars have been moved from
prism-code-editor/grammars/*
toprism-code-editor/prism/languages/*
- The
rest
property of grammars is now a rest symbol - Added custom tokenizers to grammars through a tokenize symbol
- Grammar related utilities like
clone
,extend
andinsertBefore
are now found underprism-code-editor/prism/utils
- Changed the signature of the
insertBefore
utility - Prism hooks have been removed since they were unused by all languages
- Dropped the
@types/prismjs
dependency since it's incompatible - Moved the
attr-equals
token out ofattr-value
in the markup/xml grammar. This can change some themes - Dropped support for CRLF and CR line breaks in all grammars
- Dropped the
clike
dependency from the following languages:c
,dart
,fsharp
,go
,groovy
,haxe
,java
,jolie
,kotlin
,latte
,purebasic
,qsharp
,qore
,ruby
,sqf
,squirrel
, andvala
xml
is now its own seperate language component thatmarkup
extends- Dropped the
markup
dependency fromjsx
- Removed the
t4-templating
language js-extras
has been removed and some of its features have been moved to thejavascript
grammar instead- The
markup-templating
language has been replaced by theembeddedIn
utility - Empty tokens can no longer be created by the tokenizer because empty matches are skipped
- The global regex flag on the pattern is now required for greedy tokens
Other breaking changes
There are also breaking changes unrelated to Prism:
- Removed the
TokenizeEnv
type - Changed the arguments for
tokenize
listeners. Instead of a singleTokenizeEnv
argument, the tokens, language, and value are passed as individual arguments in the aforementioned order (25cd60f) - Moved
ignoreTab
andsetIgnoreTab
toprism-code-editor/commands
(84b2515) - Removed support for a number as a search filter (ebc89fa)
- Changed the order of properties in the
Tag
tuples created by the tag matcher to be more sensible - Moved the
pce-readonly
andpce-no-selection
classes from the overlays to the scroll container. You might need to change some CSS selectors - The editor used is now passed as an third argument to the
autoIndent
andautoCloseTags
methods instead of being passed throughthis
(73e082e) - The
InputSelection
type has been made mutable (c48443e) createTagMatcher
no longer writes toeditor.extensions.matchTags
- Changed the classname of the tooltip container from
tooltip-wrapper
topce-tooltip
to avoid potential style collisions with external style sheets - Added
overflow-x: clip
to the tooltip container by default to prevent overflow in modern browsers
New features
- New public
highlightText
andhighlightTokens
functions allow you to easily do syntax highlighting outside of an editor - You can now use this library's Prism instance to do syntax highlighting in Node.js
- Tags aren't automatically closed while typing if there exists an unmatched closing tag with the same name. This is only the case with the tag matching extension added
- Added the class
pce-focus
to the editor when it's focused - Plain functions can now be used as editor extensions. These functions take the same arguments as the update method on the existing extensions, but won't be called again when the editor's options change
Fixes and improvements
- The tag- and bracket matching can no longer match together tags/brackets with different parent tokens
- The
jsdoc
language now works withjsx
andtsx
- Bracket matching has been enabled inside regex tokens
- Improved highlighting of regex tokens in all themes
- Added the missing property
rtl
to thePrismEditorElement
type (34ed0ff) - Fixed alignment issue with the
highlightCurrentWord
extension in RTL mode (1f7611d) - Almost any operator or punctuation is now allowed after javascript regex tokens (d88a25a)
- Fixed a very rare edge case where new highlighted lines would be inserted in the wrong position (326e6fc)
- Fixed issue with the markdown code block punctuation pattern (c7b9f7c)
- The Prism core is now almost 20% smaller and slightly faster than before (d142f64)
Website
- Added the
jsdoc
,js-templates
, andregex
languages - Added a tooltip to the bottom read-only editor to tell users it can't be edited
