The new json1 format works just like json except that it treats tabs as
single characters instead of 8-character tabstops.
The main use case is to allow editors to pass -fjson1 so that they can
consume the json output in a character-oriented way without breaking
backwards compatibility.
Also addresses #1048.
Add a new optional flag "-r|--root ROOTPATHS", where ROOTPATHS is a
colon separated list of paths, that will look for external sources in
alternate roots.
This is particular useful when the run-time environment does not fully
match the development environment. The #shellcheck source=file directive
is useful, but has its limitations in certain scenarios. Also, in many
cases the directive could be removed from scripts when the root flag is
used.
Script example.bash:
#!/bin/bash
source /etc/foo/config
Example usage where etc/foo/config exists in skel/foo:
# shellcheck -x -r skel/foo:skel/core example.bash
The set builtin accepts certain flags, and some longer synonyms (for
instance set -e is the same as set -o errexit) under POSIX sh. This
makes ShellCheck warn if any of the used flags and options are
undefined when targeting POSIX sh.
This fixes#990, while adding general flag-support checking for set in
the process.
Flags for the hash builtin other than [-r] are undefined under POSIX sh.
Dash also accepts [-v], while bash adds [-l] [-p filename] [-dt] aside
from [-r].
Issue https://github.com/koalaman/shellcheck/issues/1330
Addresses false positives when quoted arguments to echo begin with what
looks like a flag. Now, warn only when the first argument is a
recognized echo flag when flags are unsupported.
The only acceptable flags for the unset builtin under POSIX sh and dash
are [-fv]. Bash though, accepts [-n] too. This commits makes shellcheck
warn about this.
There are no flags for the type builtin defined under POSIX sh, nor does
dash define any. Bash, however, allows [-aftpP]. We check this now under
POSIX and dash.
This is motivated by the fact that the popularity of bats is increasing
since the creation of bats-core/bats-core.
The code is a cherry-pick of koalaman/shellcheck/bats branch.
Fixkoalaman/shellcheck#417.
