How to pass a line to the console in sublime text 2 editor

Question

I use RStudio for working with R programming language and find the ctrl+enter shortcut to send a line to the console extremely useful in troubleshooting my work.

Now I am using sublimetext2 and I would like to do the same thing in RStudio, send a line to the console.

Is there a way to send the existing line to the console or a SublimeREPL console?

Answer 1

I don't know about the console, but this is possible with SublimeREPL.

As long as you have a REPL and a file of the same language open at the same time, you can send a line (or a selection or file) to your open REPL via the SublimeREPL Source Buffer Keys. By default, Ctrl+, followed by l sends the current line to the REPL, but you can change the hotkey to Ctrl+Enter (in Python only, to protect other languages' default Ctrl+Enter functionality) by adding these lines to the top of your Preferences -> Key Bindings – User file:

{ "keys": ["ctrl+enter"], "command": "repl_transfer_current", "args": {"scope": "lines"}, "context":
    [
        { "key": "selector", "operator": "equal", "operand": "source.python", "match_all": true }
    ]
},

Other available scopes (from Preferences -> Browse Packages -> SublimeREPL/Default (Windows).sublime-keymap) are selection, file, and block (Clojure only). If you want to send a line to your REPL but not parse it immediately, you can add "action":"view_write" to the args object, like so:

{ "keys": ["ctrl+enter"], "command": "repl_transfer_current", "args": {"scope": "lines", "action": "view_write"}, "context":
    [
        { "key": "selector", "operator": "equal", "operand": "source.python", "match_all": true }
    ]
},

See the Unofficial Sublime Text 2 Docs for more information on key bindings.

In the case that the REPL is open in a different tab than your source (rather than a separate view), the source buffer hotkeys will not focus the REPL. I'm sure it's possible to implement some sort of tab-swapping toggle key, but that sounds like a problem for another question.

In addition to setting up your own key bindings, you can simply install Enhanced-R:

In Sublime:

• Cmd + Shift + P (to bring up the command palette)
• type "Install Package"
• Navigate to Enhanced-R

If you are using Sublime for mostly just R, then you can set the default syntax for the whole app. Or you can change it per file (Cmd + Shift + P again, then start typing Syntax Enhanced R)

Then, like you are used to in RStudio, you simply hit Cmd + enter to ship the code to the Console or R.app etc
