Joseph C. Sible 67e091674e Remove unnecessary maybeToList
The functions we use here are polymorphic enough to work in the [] monad,
so there's no point to use them in the Maybe monad and then convert.

Tito Sacchi 0e0de94045 Fix issue #1724
(bash: missing support for 'builtin' keyword)
Now shellcheck looks for the arguments to 'builtin' to determine
read/written variables. A change in the parser makes sure that
assignments are parsed correctly in commands that start with 'builtin'.

Benjamin Gordon f6ba500d6b Add support for basic shflags semantics
The shflags command-line flags library creates variables at runtime
with a few well-defined functions.  This causes shellcheck to spit out
lots of warnings about unassigned variables, as well as miss warnings
about unused flag variables.

We can address this with two parts:

1. Pretend that the shflags global variables are predefined like other
   shell variables so that shellcheck doesn't expect users to set them.
2. Treat DEFINE_string, DEFINE_int, etc. as new commands that create
   variables, similar to the existing read, local, mapfile, etc.

Part 1 can theoretically be addresssed without this by following sourced
files, but that doesn't help if people are otherwise not following
external sources.

The new behavior is on by default, similar to automatic bats test
behavior.

Benjamin Gordon aa3b709b5d Track whether braces were present in T_DollarBraced
References of the form $var and ${var} both map to the same structure in
the AST, which prevents any later analysis functions from distinguishing
them.  In preparation for adding checks that need this info, add a Bool
to T_DollarBraced that tracks whether the braces were seen at parsing
time and update all references so that this change is a no-op.

Vidar Holen c97cb8cf54 Merge branch 'bats-support' of https://github.com/damienrg/shellcheck 2019-01-20 13:35:12 -08:00
Vidar Holen f187382a0c Add bats support
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.

Fix koalaman/shellcheck#417.

Tito Sacchi a4b9cec9f0 Fix #1369 (Use file extension to detect shell)
The precedence order that is used to determine the shell
is the following:
1. ShellCheck directive
2. Shebang
3. File extension
A new field `asFallbackShell` has been
added to the record type `AnalysisSpec`.
