Vidar Holen c6c12f52bd Expand root paths into source paths 2019-04-24 18:51:24 -07:00
Pontus Andersson af46758ff1 Add option to look for sources in alternate root paths 
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

Cristian Adrián Ontivero d3f6e045e2 Check wait flags in dash & POSIX sh 
Flags for the wait builtin are undefined under both POSIX sh and dash.
Bash though, accepts [-fn].

Vidar Holen d984f8cbe7 Don't look at 'set' options after a non-literal. 2019-02-08 22:36:22 -08:00
Cristian Adrián Ontivero acef53be9c Check set flags under dash & POSIX sh (fixes #990) 
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.

Check hash flags under dash and POSIX sh 
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].

Gandalf- 112a7d8b9b Issue 1330 unsupported echo flags 
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.

Check unset flags under dash and POSIX sh 
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.

Cristian Adrián Ontivero 63a259e5be
Check type flags under dash and POSIX sh (fixes #1471) 
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.
