Carlos,
Sorry that you are seeing this issue.
1. What exact problem are you seeing with the format? Does it not format at all or does it not format as expected?
If it does not format at all, then please verify if the Ctrl+Shift+F is bound to format with CodeMix editor. Go to Window > Preferences > General > Keys, enter Ctrl+Shift+F in the filter box and check if there is an entry for format.
2. If it does not format as expected, then please share with us the cases where it fails. If possible, please attach a screencast/gif to help us get a visual. JavaScript formatter settings are available here : Window > Preferences > CodeMix > Extensions > TypeScript > JavaScript Format. You can tweak them as per your choice.
3. Does the format not work in a particular JS file or all the JS files in the workspace? How about a new workspace?
4. If the issue persists, then please share the .log file located at workspace dir/.metadata/.log (rename the extension to .txt and attach it here) along with the Eclipse version details to help us investigate further.
Apologies for inconvenience caused.
