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)]
