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 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].

Ng Zhi An 461be74976 Realign virtual tabs when applying fix
Fix an off-by-one error, in the case that is commented `should never happen`.
It happens when the end of a range is the at the end of a line.
In that case we should update the real column count (probably just by +1)
instead of returning it.

I modified makeNonVirtual to use a helper, realign, that works on
Ranged. That way we can share the code to realign a PositionedComment
and also a Replacement.

Ng Zhi An 95a8cf93c9 Add check for ambiguous nullary test
Given an input like `if [[ $(a) ]]; then ...`, this is a implicit `-n` test,
so it works like `if [[ -n $(a) ]]; then ...`. Users might confuse this for
a check for the exit code of the command a, which should be tested with:

    if a; then
        ...

We warn the user to be more explicity and specifity the `-n`.
