shellcheck v0.7.1 complains about a bunch of issues:
SC1083: This { is literal. Check expression (missing ;/\n?) or quote it.
SC1083: This } is literal. Check expression (missing ;/\n?) or quote it.
SC1090: Can't follow non-constant source. Use a directive to specify location.
SC2034: foo appears unused. Verify it or export it.
SC2059: Don't use variables in the printf format string. Use printf '..%s..' "$foo".
SC2128: Expanding an array without an index only gives the first element.
SC2148: Tips depend on target shell and yours is unknown. Add a shebang or a 'shell' directive.
SC2155: Declare and assign separately to avoid masking return values.
SC2162: read without -r will mangle backslashes.
SC2164: Use 'cd ... || exit' or 'cd ... || return' in case cd fails.
SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?.
SC2207: Prefer mapfile or read -a to split command output (or quote to avoid splitting).
SC2237: Use [ -z .. ] instead of ! [ -n .. ].
We're still bound to support shellcheck v0.3.4 and sadly this version
fails hard when using the modern "shellcheck source=" directives to
address SC1090 and SC1091. It's failing like:
| not ok 1 source/functions/init:8:28: note: The mentioned parser error was in this then clause. [SC1009]
| not ok 2 source/functions/init:10:3: error: Couldn't parse this shellcheck annotation. [SC1073]
| not ok 3 source/functions/init:10:16: error: Unexpected "s". Fix any mentioned problems and try again. [SC1072]
So until we can get rid of supporting this ancient shellcheck version,
instead of using:
| # shellcheck source=etc/ngcp-config/ngcpcfg.cfg
| # shellcheck source=functions/init
| # shellcheck source=functions/logs
| # shellcheck source=functions/main
we need to place disable=SC1090 and disable=SC1091 accordingly.
