[solved] No search history in apps using readline after installing zsh

Hello. I'm an intensive user of applications that uses readline, for example octave, ipython2 and sbcl with rlwrap. I use history search with just pressing the up and down arrows a lot, as explained in the wiki. I decided to give zsh a try, and so far I like it. I have configured it to behave like vim, and history backwards search works correctly in the zsh shell by pressing the up and down arrows. The problem is that now history backwards search stopped working in octave, ipython, etc, even tough I didn't modified .bashrc or .inputrc. Changing back to bash didn't work, because now not even bash has history search using the up and down arrows. Ctrl+R still works, but I don't understand why I can't restore the previous behaviour.

Here is my .inputrc

# mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving
"\e[1;5C": forward-word
"\e[1;5D": backward-word
"\e[5C": forward-word
"\e[5D": backward-word
"\e\e[C": forward-word
"\e\e[D": backward-word

#History completion
"\e[A": history-search-backward
"\e[B": history-search-forward

#autocompletar
set show-all-if-ambiguous on
set show-all-if-unmodified on

My zshrc is like this (sorry because it's really messy, I deleted aliases and some functions.) I don't know if it's relevant.

Re: [solved] No search history in apps using readline after installing zsh

Zsh doesn't use readline, it uses zle.

Re: [solved] No search history in apps using readline after installing zsh

Yes, I know that. But octave and rlwrap use GNU readline, and that uses inputrc for its configuration. Apparently zle doesn't affect them. That's why I don't know why backwards search history stopped working after changing to zsh. I changed several options in inputrc (like enabling vim mode) and they work, they affect the behaviour of many applications even tough my shell is zsh right now. But still, my arrows still only show the previous command when I press them.

Apparently, as far as I know it's no possible to use zle as a wrapper for other applications, like rlwrap. And I don't know if its possible to make zshrc or other config file to take control of other applications that use readline.

Re: [solved] No search history in apps using readline after installing zsh

Well, I solved it. The problem was in my .zshrc file. I don't know why, but the function zle-line-finish was interfering with the other applications. I just deleted it. Now history search works in all applications, and my prompt still says if  I'm in command or insert mode.
