Open Vim from a Rakefile?

Question

I am creating a journal application for personal notes and have the following in my `Rakefile`: ``` task :new do entry_name = "Entries/#{Time.now.to_s.gsub(/[-\ :]+/, '.').gsub(/.0500+/,'')}.md" `touch #{entry_name}` `echo "# $(date)" >> #{entry_name}` end ``` The last part I would like to include is the opening of the Vim text editor but I am unable to figure out how to open it as if I called it directly from the bash terminal. I have tried: ``` vim #{entry_name} ``` but unfortunately I think both of those open it as a background process. I have been referencing "6 Ways to Run Shell Commands in Ruby".

Accepted Answer

As in the article you referenced, ```s run the command in a subshell within the current process, but the real problem is that it's trying to take the output from the command run as well, which doesn't play nice with Vim.

You can either:

Use `exec` to replace the current process with the new one (note that the Ruby/Rake process will end once you've called `exec`, and nothing after it will run).

Use `system` to create a subshell like ```s, but avoids the problem of trying to grab Vim's stdout. Unlike `exec`, after Vim terminates, Ruby will continue.
