Use ft=dockerfile? (lowercase)

[blueyed]

Vim itself uses filetype=dockerfile, whereas Dockerfile is used here.
Is there a specific reason for this? I think it should/could use the default filetype here also.

(Via neomake/neomake#2498)

Hm, I believe there's no particular reason for than except the historical one.

The reason for change that to the original vim behavior is that other plugins, which working on this filetype doesn't work without additional fixes in the vimrc.
Original behavior: au BufNewFile,BufRead Containerfile,Dockerfile,*.Dockerfile setf dockerfile
Current example for that is 'ycm-core/lsp-examples' which uses the original behavior.

Best regards

Only as an FYI, not knowing the best way to proceed, however, the filetype Dockerfile prevented the docker tree-sitter to work as expected. It threw a "symbol not recognized error". Here is the link to that issue. Manually overriding the autocmd in this plugin to rename the filetype to dockerfile fixed the issue. Perhaps some of the features in the plugin are inherently incompatible with tree-sitter?

Just ran into this issue as well. :-( It is breaking tree_sitter which is trying to load a compiled library called tree_sitter_<filetype> and running into casing issues as it expects tree_sitter_dockerfile.

The workaround for me is to override treesitter as follows:

vim.treesitter.language.register("dockerfile", "Dockerfile")
