Detect filetype on buffer save too This allow kaking a new file, add a shebang in the first line, and get the right filetype detected automatically on save. 2020-11-17 22:32:09 +01:00			`define-command -hidden file-detection %{ evaluate-commands %sh{`
transform mimetype to a fallback option The option is now used as a fallback when detection by extension fails. Some scripts like `base/mail.kak` and `base/html.kak` still rely heavily on it. 2016-12-06 14:40:14 +01:00			`if [ -z "${kak_opt_filetype}" ]; then`
Fix filetype detection The -i flag on Mac OS means: ჻ man file \| grep -i -- -i -i If the file is a regular file, do not classify its contents. The --mime-type option is (mostly) portable: - Linux uses --mime-type - macOS uses --mime-type - FreeBSD uses --mime-type - NetBSD uses --mime-type - OpenBSD uses --mime-type and does not use the same implementation as everybody else - Solaris does not support MIME types at all 2020-02-22 06:25:57 +01:00			`mime=$(file -b --mime-type -L "${kak_buffile}")`

Clear unwanted environment variable This adds two things I forgot in 9a7d8df4 (Avoid accidentally using environment variables in sh scopes) Mea culpa, the problem was that I was skipping matches with "filetype" because that's usually just a hook parameter as in "WinSetOption filetype=.." rg --pcre2 '\b(?!filetype=)\w+=' rc/ So I missed these two cases where a shell variable is actually called "filetype". The one in git.kak was not a problem because show_git_cmd_output is only ever called with sane inputs. However, file.kak does use the filetype environment variable for many mime types, for example: filetype=somefiletype\''; echo -debug injection; nop '\' kak /dev/null Will run the echo since /dev/null has mime type "inode/chardevice" 2020-09-01 21:38:04 +02:00			`*) exit ;;`

rc file-detection hook group Add a group to the `file-detection` hooks. There's no way to remove hooks without a group. With this patch, you'll be able to remove those `file-detection` hooks manually. There's no need for two separate groups since if you wanted to remove only one, you could run `remove-hooks` and then only add one again.
