This commit makes `:modeline-parse` grab all lines that look like
modelines, and lets the parser deal with invalid formats.
This allows actually printing an error on unsupported modelines
formats, instead of ignoring them upfront.
This commit prevents specially crafted modelines from making the
editor execute arbitrary Kakoune commands.
By using a tabulation character as a separator, commands can be
injected in the value of the options listed in the modeline. For
example:
# kak: tabstop=2;set-option buffer pwned yes
Fixes#3735.
This commit addresses an off-by-one error that selected `modelines`+1
lines when looking for modelines in a buffer.
Note that setting `modelines` to 0 will still select one line.
Fixes#3733.
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"
Similarly to the <semicolon> key, make it easier to write
`:execute-keys` commands by replacing <percent> with `%`.
Highlighters can keep escaping the sign when regular expressions are
not quoted, but built-in scripts that use `%` as an editing primitive
have been modified to use the named key, for clarity.
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
Check if buffile is a full path by checking for the beginning
'/' character in editorconfig-load command. This avoids a parsing
error from feeding a *scratch*/*debug*/*grep*/etc. buffer name to the
editorcofig command. Don't clear editorconfig hooks until after checking
for a valid bufffile path. This way, opening the *debug* buffer will
not clear the hooks from a previously parsed .editorconfig file. If
trim_trailing_whitespace is true, print the hook directly from awk. This
removes the need to save a editorcofig_trim_trailing_whitespace option.
Note: Setting the max_line_length requires a window to be created.
Therefore, a global hook to load .editorconfig settings should be:
hook global WinCreate .* %{editorconfig-load}
