A Brackets extension to enable W3C validation support. To use this extension, open any HTML file and then check the bottom right corner of Brackets (where all files are checked) and look for either the green icon (all is well) or the yellow warning sign (issues). Clicking the icon will open a panel with the current issues.
[9/9/2014] Two big updates by Denisov21. First, F9 can fire a re-scan. And then he added an Italian language file. Go Italy!
[8/28/2014] Added a submenu (under "Edit") to update the W3C validation (fixed bug when connection lost). Credit goes to valx76 (cfjedimaster#16)
[5/19/2014] Removed an annoying console message.
[4/15/2014] Requires Brackets Sprint 38. Supports sexy new async linting.
[2/23/2014] Fix bug 9 and another few things. Note that zebra striping isn't working anymore, but in theory, Sprint 37 will allow me to switch to the built in linting API and I won't have to care.
[10/3/2013] Fix bug where the close icon wasn't working. There is a new bug though - links in the results open a small window AND a Chrome tab.
[5/24/2013] Set version to 2, added package.json support.
[4/21/2013] Remove links in explanation that just point to the 'add' function. Make links open in new window.
[11/12/2012] Update code to properly insert the content over the status bar. Also made it resizable.
[9/26/2012] Fixes some display issues.
Currently it is performing a HTTP request on file edits. Not sure I like that.
As with the other extensions I built, it is heavily based on the work of Jonathan Rowny.
