Input missing, output on Input line in sublimerepl python

Question

Basically, after getting Sublime text 2 and sumblimeREPL up and running, I am having issues when I send code. For instance, in the below screenshot, I enter the code on the left line by line (ctrl+,l), or by block/selection but nothing shows up except the output. In[3]-In[6] I was attempting to run the x and y lines only. Is this the intended behavior? I would have assumed yes, except that all the output is being displayed on the input lines. The only other language I have tried so far is R, and it does not have this issues. Also it is the same issue in both python and ipython. Any ideas?

Answer 1

First off, I'd strongly suggest upgrading to IPython 1.1.0, as while the issue likely isn't related to the older version, it's well worth the upgrade, especially if you use it a lot.

If you open Preferences -> Package Settings -> SublimeREPL -> Settings - Default, you'll notice that the last line is "show_transferred_text": false. I'm on OS X, but when I have this set to false, I see the same behavior you do - the result of the expression printed on an In [#] line, with another blank line following it, ready for the next expression. However, if I set this variable to true (by copying the entire contents of the file, opening Preferences -> Package Settings -> SublimeREPL -> Settings - User, pasting everything in there, then changing settings and saving), then I see different behavior when transferring a line: The expression is printed on the In [#] line, and the result is printed below.

The reason you didn't see any results when evaluating the assignments to x and y is because nothing is returned, by default.

By way of explanation as to why the Python/IPython REPLs work this way, while the R one doesn't, is because SublimeREPL is very modular, and for the most part is just a thin wrapper surrounding native code. Therefore, the exact mechanism of transferring and displaying data may differ from Python to Ruby to R to Clojure, for example, and you may see slightly different behaviors.

Answer 2

I wanted something more interactive. I wanted both the In[#] with text followed by an Out[#] with the output. I also did not want to switch from my source code to REPL just to get a damn Out[#].

Like this, for example... The solution I came up with is a lot more complicated than the post above but you get that interactive feel that one gets when using R with Sublime Text. You can find my solution here: https://stackoverflow.com/a/27562036/3987905

Be sure to keep "show_transferred_text": false. Enabling it appears to mess up the plug-in. Hope it helps.
