DevTools Digest, October 2016
Hey hey, Kayce here, back again for another digest to update you on what's new in DevTools since last month.
New features in the Console
In Chrome 56, which is currently in Canary, the DevTools Console is powered by CodeMirror. This enables a whole bunch of new features, like:
Syntax highlighting as you type. Previously, DevTools could only highlight syntax after a code block had been evaluated.
Matching parenthesis / bracket / brace highlighting. If you've got an extra parenthesis, bracket, or brace, DevTools highlights it red.
Matching parentheses, brackets, or braces are highlighted grey when your cursor is next to one of them.
Smart return. When you type out a multi-line code block, DevTools
now knows whether to create a new line or execute your code each time you
press Enter. For example, suppose you want to
evaluate the following for loop in the Console:
for (var i = 0; i < 5; i++) {
console.log(i);
}
In the past, hitting Enter after typing out the first line would have caused DevTools to evaluate the line, causing an error. To continue the code block to a new line, you would have had to held Shift before pressing Enter. In contrast, now DevTools just automatically continues the code block on a new line after you hit Enter, as you expect it would.
Multiple cursors. Hold Command (Mac) or Control+Alt (Windows, Linux) and then click.
Canary now highlights non-top contexts red
If you've worked in the Console lately, you might have been bitten by a
nasty little bug that was setting the execution context
selector to values
other than top.
That bug should be now be fixed in Stable, but, just to be safe, the DevTools
in Canary (Chrome 56) now warns you that you're not in the top context by
highlighting the selector red.
New user agent: UC Browser
You can now select UC Browser for iOS, Android, or Windows Phone from the Network conditions drawer tab.
