This commit renames `lint-enable` into `lint-show-diagnostics`,
makes it hidden, and calls it automatically after diagnostics have
been recovered by `:lint-cleaned-selections`.
The `lint-disable` command becomes `lint-hide-diagnostics`.
The concept of "enabling" diagnostics was inherited from the Clang
support script, but in that case it's not clear why calling `:lint`
should do the work but not render it (similarly to `:spell`).
The `lint-show` command was also renamed into a more descriptive
`lint-show-current-line`.
Calling `:lint-buffer` when `lintcmd` is empty results in a temporary
directory being created, but never removed when the underlying linting
code errors out.
In Ruby, identifiers can end with a `!` or `?` too, which means that `class!` or `end?`are not actually keywords, but regular identifiers. This fixes that by not using `\b` but `[^0-9A-Za-z_!?]` instead in some places.
Incrementally setting the lint variables triggers multiple refreshes,
including the text jumping as the guttter column is removed and re-
added. This causes the info message to disappear when linting is done
on NormalIdle.
Looks like hyphens and periods are sometimes printed as part of
git-log(1)’s graphing feature; for example, in this repository:
git log --graph 55e7f857
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
There might legitimately be "|" characters in the message, so
we want to stop at the first one, the one that delimits the message location
from the message text.
