I have the following SourceGraph structured search: repo:… file:… "tls_certs" {...default = {...}...} which correctly matches:

variable "tls_certs" {
  description = "…"
  type        = map(string)
  default = {
    …
  }
}

It's currently highlighting the entire "tls_certs" block. I would like it to highlight only the default = block. Assuming that's possible, how would that be done?

(I'm assuming you want to scope your search to Terraform files based on the example match provided)

Try this and see if it works for you: :[~[\s\n]]default = {...} lang:Terraform

It'll match a block of the form default = {...} that's preceded by whitespace or a newline. It's not strictly guaranteed to only match nested structures, but it seems to work well with the lang:Terraform filter.

It uses both the ... and the :[~regexp] syntax of structural search. (Syntax reference docs: https://docs.sourcegraph.com/code_search/reference/structural#syntax-reference)

Example: https://sourcegraph.com/search?q=context:global+:%5B~%5B%5Cs%5Cn%5D%5Ddefault+%3D+%7B...%7D+lang:Terraform+-repo:%5Egithub%5C.com/Wilfred/difftastic$&patternType=structural

  • The question I provided already matches fine. Currently, SourceGraph is highlighting the entire `tls_certs` block. I want it to highlight only the `default` block without matching `default` blocks not in a `tls_certs` block. – Noel Yap Oct 22 '22 at 17:09
  • If I replace the `...default` in my query with `:[~[\s\n]]default`, SourceGraph responds with `No results matched your query`. – Noel Yap Oct 22 '22 at 18:40

    I see -- unfortunately it's not possible to highlight only a submatch of an overall pattern in the way you're describing (i.e. only matching `tls_certs` blocks, _and then_ only highlighting the `default` block within those blocks) – CeramicBezel Oct 24 '22 at 20:21
