How to leverage this for HSX

[C-alcium]

Hi there, would you happen to know how I can leverage this plugin to achieve HSX highlighting support?

Issuing the command

:call SyntaxRange#include('[hsx|', '|]', 'haskell', 'NonText')

throws up an error stating that I did not include enough arguments. you can find HSX here, it's essentially JSX but for haskell: https://ihp.digitallyinduced.com/Guide/hsx.html

Starts with: [hsx|
Ends with: |]

Only inside of .hs (Haskell) files.

and ideally it would highlight the region as HTML

Any help would be much appreciated.

The first two arguments of SyntaxRange#Include() are regular expressions, but as you did not escape the [ and ] characters, Vim parses the entire resulting start="[hsx" end="|]" expression as one argument, and then (a bit misleadingly) complains about the missing (end=...) argument. So you either need to put \V in front of each pattern to make it "very nomagic", or simply escape the character as \[.

If I understand the syntax correctly, this is HTML embedded inside Haskell. So the third argument would be html. (If you have a syntax for that "blaze HTML" dialect, that would be even better.)

So the call should look like this:

call SyntaxRange#Include('\[hsx|', '|\]', 'html', 'NonText')

To apply this automatically for the haskell filetype, put it into a script in ~/.vim/after/syntax/haskell/SyntaxInclude.vim.
