From bde6bb0d37eeeb68b76e305aee1636d037f664e4 Mon Sep 17 00:00:00 2001 From: "Tu, Do" Date: Sat, 30 Aug 2014 14:03:31 +0700 Subject: [PATCH] Improve Helm configuration The current prelude-helm only uses a single command of Helm, which is a waste given how Helm contains many other commands. When prelude-helm is activated, users should be able to utilize all of these useful commands. If a user wants to use Helm, he will want to use all of its features anyway. prelude-helm is configured that it is able to be used with this [guide](http://tuhdo.github.io/helm-intro.html). --- README.md | 9 +++- modules/prelude-helm.el | 102 ++++++++++++++++++++++++++++++++-------- 2 files changed, 90 insertions(+), 21 deletions(-) diff --git a/README.md b/README.md index ba875e2..5e5fc57 100644 --- a/README.md +++ b/README.md @@ -296,7 +296,6 @@ Keybinding | Description C-c t | Open a terminal emulator (`ansi-term`).
