Extended by:

ShConfig

Included in:

ShConfig

Defined in:

lib/shell_helpers/sh.rb

Overview

this modules deal with default options, paths and arg handling for different programs, while letting the user control Exemples: ShConfig.launch(:ls, "/", config: {default_opts: ["-l"]}) => ["ls", "-l", "/", {}] ShConfig.launch(:ls, "/", config: {default_opts: ["-l"]}, method: :sh) ShConfig.launch(:ls, "/", config: {default_opts: ["-l"]}) { |*args| SH.sh(*args) } ShConfig.launch(:ls, "/", config: {ls: {wrap: ->(cmd,*args, &b) { b.call(cmd, '-l', *args) } }}, method: :sh)
