Javascript syntax highlighting not working in script tag

[jsaak]

If i use plain ecmascript, the syntax highlighting is not working.

For a workaround i edited syntax/vue.vim and added
call s:register_language('javascript', 'script')

And modified my source to
<script lang="javascript">

That shouldn't be necessary.
Have you tried disabling other plugins and progressively enabling them to see when it fails?

[jsaak]

I disabled all plugins. And it still does not work. Using
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Nov 17 2016 06:36:04)

Also there is a strange issue when using with NERDcommenter, that sometimes it is using the wrong comment format. I do not know why, or if it is related or not.

I don't know what to tell you... script section should be detected as javascript by default...

JavaScript and CSS highlighting is handled by the HTML syntax script. Does it get highlighted when you run :set filetype=html?

OMG, did I forget how my own script works? 😰

[jsaak]

Ok, It seems we are getting close. It does syntax highlight using the html.vim file.

I expected it to use javascript.vim. Both othree/html5.vim and built in html -> javascript syntax highlighting looks so strange..

I am pretty bad at vimscript, can you tell me how to make syntax/javascript.vim the default one? (without explicitly naming it lake this: <script lang="javascript">

Hi, I am still facing this issue while using latest version of this plugin.

Summary

• <script> tag with no lang attribute is not highlighted. ( ft=vue )
• Adding lang="ts" enables syntax highlighting
• setting ft=html or ft=html.vue enables syntax highlighting, but setting ft=vue.html do not enables syntax

@harish2704 I had a similiar problem. My highlighting was not complete e.g. Strings had no colorization. I just fixed that problem with adding "vue" as filetype for my other javscript plugin:

Plug 'pangloss/vim-javascript', { 'for': ['javascript', 'javascript.jsx', 'html', 'vue'] }

I just wanted to keep this info here if someone is faceing the same problem. It seems that in my case the plugins are blocking each other.

edit: I use nvim 0.2.2...

@jsaak @harish2704 Could you provide steps to reproduce it with a clean vimrc?

[jsaak]

@adriaanzon You had the answer previously. "JavaScript and CSS highlighting is handled by the HTML syntax script.". It is true, and that is my problem. I expected this script to use javascript.vim and css.vim.
