I had assumed it works like :paste in Vim, activating a kind of "paste mode" where everything pasted into the terminal is modified as the help text suggests. Ok, I just noticed I should have actually _read_ the help text, not just scanned it. ;-) Sorry for the confusion. Stefan

Makes it hard to paste code directly into the interpreter. The combination of editor, debugger and interpreter is what I miss most from Matlab. In Matlab we can have a function or script open in an editor, and use it directly from the interpreter. No need to reimport or anything: edit and invoke. It is also possible to paste data directly from the clipboard into variables in the interpreter. ipython does not have that annoying >>> prompt. |
