Protocol Buffers not listing on repo

[psybers]

For one of my repos (https://github.com/boalang/compiler) I noticed the detected languages does not list Protocol Buffers. It appears there is support for detected protobuf in Linguist:

src/proto/ast.proto: 560 lines (542 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/code.proto: 71 lines (67 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/control.proto: 51 lines (46 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/diff.proto: 125 lines (114 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/graph.proto: 21 lines (19 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/issues.proto: 158 lines (149 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/shared.proto: 51 lines (38 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer
src/proto/toplevel.proto: 83 lines (80 sloc)
  type:      Text
  mime type: text/plain
  language:  Protocol Buffer

But when I run on the whole repository, it does not show any Protocol Buffer results:

97.55%  2267410    Java
2.12%   49201      ANTLR
0.10%   2239       JavaScript
0.08%   1909       PHP
0.06%   1441       HTML
0.04%   997        CSS
0.03%   694        Batchfile
0.02%   520        Shell

Shouldn't this list the files above?

Shouldn't this list the files above?

Nope. Protobuf files are considered data:

https://github.com/github/linguist/blob/5a0c74277548122267d84283910abd5e0b89380e/lib/linguist/languages.yml#L5282-L5293

... so are not considered by default (from "How Linguist works"):

Linguist starts by going through all the files in a repository and excludes all files that it determines to be binary data, vendored code, generated code, documentation, or are defined as data (e.g. SQL) or prose (e.g. Markdown) languages, whilst taking into account any overrides.

If you want them to count, you'll need to use the linguist-detectable override.

Great, thank you for the pointer to the overrides docs. I didn't spot that before! That fixed my specific case (and other issues!).
