What is this
Evaluate selected text as ruby code then print or insert.
I love Ruby, one of the goodness of ruby is it has many way to express Array , String , etc..
When I write other Language such as Python or JavaScript and want to prepare
array [ "a", "b", "c", "d" ].
You can write %w(a b c d) then select text , then execute :RubyEvalInsert to
insert [ "a", "b", "c", "d" ] to buffer.
Requirement
gem install awesome_print
Example keymap
vnoremap <silent> <Space>p :<C-u>RubyEvalPrint<CR>
vnoremap <silent> <Space>i :<C-u>RubyEvalInsert<CR>
nnoremap <silent> <Space>p :<C-u>RubyEvalPrint<CR>
nnoremap <silent> <Space>i :<C-u>RubyEvalInsert<CR>
Usage Example
In following what I want you to try is..
set cursor position to ruby fragment, then execute :RubyEvalInsert
insert 10 size array for random number from 1 to 6 to buffer
10.times.map {|n| rand(6) + 1}
insert array for "A" to "Z"
("A".."Z").to_a.join()
to insert {"port"=>"80", "ip"=>"192.168.1.1"} to buffer with minimal key stroke
Hash[*%w(port 80 ip 192.168.1.1)]
