Is there anyway of getting HTML markups and highlighting when using heredoc or newdoc in PHP?
Like in sublime you can type the wanted markup language after the <<< to get the correct markup, so like:
<<<HTML blablabla HTML;

I really want this to work in brackets also since a lot of HTML get's written in heredoc and it's all just plain orange.

Hope someone can help me out!

Best Regards

Hi @cisco92,

can you give an example? It seems that Heredoc should work out of the box (related: codemirror/CodeMirror#3421).

Which syntax highlight mode are you using?

As you see in the picture the code in Heredoc is not highlighting correctly..

In the bottom right of Brackets PHP is selected.

Thanks @cisco92,

The Heredoc part seems to be working as it should, as Heredoc can contain any file or input stream literal. Sadly that means that means that the contents could be highlighted inside the Heredoc in nearly any way possible, which is why CodeMirror opts to just highlight interpolated variables.

The solution would be some kind of mixed mode, where the contents of the Heredoc would be highlighted according to the start/terminating strings. I suggest you'll file this upstream ( , but most likely this would be better handled as an external plugin.

PHP mode: Heredoc strings and syntax highlighting #4550


Filed codemirror/CodeMirror#4550.
The CodeMirror mantainer is open to accept a PR but he will not implement himself.
