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. Addresses #1597	2019-06-25 12:14:54 -06:00
Benjamin Gordon	64c9c83cc8	SC2250: New optional check for braces around variable references ... Always using braces makes it harder to accidentally change a variable by pasting other text next to it, but the warning is off by default because it's definitely a style preference. Omit special and positional variables from the check because appending additional characters to them already doesn't change parsing.	2019-05-14 11:01:38 -06:00
Benjamin Gordon	0358090b3c	Refactor definition of special variables. ... This ensures that the parser and other places that refer to special variables can use the same list.	2019-05-14 08:57:56 -06:00

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.	2019-01-20 14:59:37 +01:00
