Remembering all those capistrano tasks can be tough for the sleep-impaired startup employee…. Help yourself out with this autocomplete script:
[ruby]
#!/usr/bin/env ruby
# Save this somewhere, chmod 755 it, then add
# complete -C path/to/this/script -o default cap
# to your ~/.bashrc
#
# If you update your tasks, just $ rm ~/.captabs*
#
exit 0 unless /^cap\b/ =~ ENV["COMP_LINE"]
def cap_silent_tasks
if File.exists?(dotcache = File.join(File.expand_path(‘~’), “.captabs-#{Dir.pwd.hash}”))
File.read(dotcache)
else
tasks = `cap -qT`
tasks = tasks.select{|task| task =~ /^cap/ }.join
File.open(dotcache, ‘w’) { |f| f.puts tasks }
tasks
end
end
after_match = $’
task_match = (after_match.empty? || after_match =~ /\s$/) ? nil : after_match.split.last
tasks = cap_silent_tasks.split(“\n”)[1..-1].map { |line| line.split[1] }
tasks = tasks.select { |t| /^#{Regexp.escape task_match}/ =~ t } if task_match
# handle namespaces
if task_match =~ /^([-\w:]+:)/
upto_last_colon = $1
after_match = $’
tasks = tasks.map { |t| (t =~ /^#{Regexp.escape upto_last_colon}([-\w:]+)$/) ? “#{$1}” : t }
end
puts tasks
exit 0
