Custom highlights (java file) not applied in preview window

[idelice]

Description

I have applied some custom highlight in my lazy.lua file using LazyVim, but they are not applied to the preview window using Telescope. Here's my `/config/options/ file:

local highlight_definitions = {
  ["JavaVarHighlight"] = { fg = keyword },

  ["@lsp.type.annotation.java"] = { fg = yellowAnnotation },
  ["@lsp.type.class.java"] = { fg = light },
  ["@lsp.type.interface.java"] = { fg = light },
  ["@lsp.type.property.java"] = { fg = purple },
  ["@lsp.type.enum.java"] = { fg = light },
  ["@lsp.type.enumMember.java"] = { fg = light },
  ["@lsp.type.namespace.java"] = { fg = light },
  ["@lsp.type.parameter.java"] = { fg = light },
  ["@lsp.type.method.java"] = { fg = light },
  ["@lsp.type.variable.java"] = { fg = light },
  ["@lsp.type.keyword.java"] = { fg = keyword },
  ["@lsp.typemod.parameter.declaration.java"] = { fg = light },
  ["@lsp.typemod.variable.declaration.java"] = { fg = light },
  ["@lsp.typemod.class.importDeclaration.java"] = { fg = light },
  ["@lsp.typemod.method.declaration.java"] = { fg = methodName },
  ["@lsp.typemod.enumMember.static.java"] = { fg = purple },

  ["@type.java"] = { fg = keyword },
  ["@type.qualifier.java"] = { fg = keyword },
  ["@type.builtin.java"] = { fg = keyword },

  ["@punctuation.bracket.java"] = { fg = light },
  ["@punctuation.delimiter.java"] = { fg = light },

  ["@keyword.java"] = { fg = keyword },
  ["@keyword.operator.java"] = { fg = keyword },
  ["@keyword.return.java"] = { fg = keyword },

  ["@variable.builtin.java"] = { fg = keyword },
  ["@constant.builtin.java"] = { fg = keyword },

  ["@operator.java"] = { fg = light },
  ["@string.escape.java"] = { fg = keyword },
  ["@method.call.java"] = { bold = false },
  ["@method.java"] = { bold = false },
  ["@conditional.java"] = { fg = keyword },
  ["@exception.java"] = { fg = keyword },
  ["@include.java"] = { fg = keyword },
  ["@boolean.java"] = { fg = keyword },
  ["@number.java"] = { fg = integerBlue },
  ["@repeat.java"] = { fg = keyword },
  ["@string.java"] = { fg = stringGreen },
  ["@attribute.java"] = { fg = yellowAnnotation },
}

      end
      highlight_cmd = highlight_cmd .. " " .. setting .. "=" .. value

Steps to reproduce

1. Use LazyVim distro
2. update config/options with what I have provided
3. install jdtls
4. open java file
5. open telescope and look at preview window

Expected behavior

I expect my custom highlights are applied in the preview window

Actual behavior

Default highlights are applied

Minimal config

Can you provide a minimal config showcasing this is actually a telescope issue? I can't really afford to debug everyone's config. And the snippet provided isn't even something I can directly copy-paste into my config.

[idelice]

What I'm missing is configurating telescope to apply the custom highlights that I've applied.

Can you show me a quick example on how to apply highlights using telescope builtin preview config?

[jamestrew]

I think generally people just stick with colorschemes or colorscheme builders for more custom stuff. Theoretically, your code looks fine to me at first glance but it's hard to say why telescope's buffer previewer isn't respecting it without more context behind the rest of your config.

Here's a minimal config I've created to replicate what I think you're looking to accomplish. I'm using lua instead of java since I don't have a treesitter parser for java. You can play around with the color but it looks like telescope is respecting the custom color so I suspect the issue is with your configuration rather than telescope. Unfortunately, I can't help you much there without more context.
