I want to apply word completion on isearch shell. When I press tab ^I shows up on the shell instead of completing the word and show up a window for suggestions.

enter image description here

=> Is it possible to complete a word on isearch shell?

  • An interesting point is what information should it use for providing completion? It needs to guess somehow the strings you want to search.

  • I just want it to detect information on the opened file (ex: Driver.py on the example I gave.)

The question seems unclear. What is "isearch shell"?

You seem to be using TAB during Isearch and expecting completion against previous search strings (?). If so, the key you want is C-M-TAB (not TAB), which is bound to isearch-complete in isearch-mode-map.

But you say "complete a word", not complete against a previous search pattern, so the question seems quite unclear.

If you are just looking for full-word searching, that's on M-s w while isearching.

  • I am not sure for the proper definition for it, I try to refer when I do a isearch the interaction shell that show up on the bottom of the emacs

  • That's the echo area (being used kind of as if it were the minibuffer). But what are you asking about it?

  • For example I have a hello_world and hello variables on my file. When I type he into isearch and press tab I want it to complete into hello_world and press tab again complete into hello (I think this is behavior of auto-complete). But on my case when I press tab ^I shows up instead of doing a completion

  • AFAIK, Isearch does not have such completion.

  • @alper It's not integrated with isearch but you might want to look at hippie-expand.
