How do I make vi editing-mode work in IRB when using RVM?

阅读更多关于 How do I make vi editing-mode work in IRB when using RVM?

问题 I " set editing-mode vi " in my .inputrc on my Mac OS system, which allows vi editing in IRB. When I'm using a RVM Ruby, the IRB sessions don't process this directive. Does anyone know a solution? 回答1: Have you got set -o vi set, either at the command-line or in one of your startup scripts? That turns it on for the shell. I have both " set editing-mode vi " and set -o vi and have Vi-like editing in IRB. EDIT: Try creating ~/.editrc , put bind -v in it. Snow Leopard has support for editline

问题 I would like Vim to help me indent my XML files like my C code. However, when I use gg=G It just sets everything to the left. Do I need to designate a syntax? Is XML recognized as a language? 回答1: Put filetype plugin indent on in your .vimrc to have Vim automatically identify .xml files as xml. You might need to put set nocompatible before that. If the file extension is not .xml, you can make Vim threat it like xml by using :set filetype=xml After you do that, Vim's autoindention (and syntax

问题 How can I limit the search scope in Vim to the function/class/code block that the cursor is currently in, without having to figure out what the line numbers are? Being able to search in the visual selection would also do, as there are methods for selecting the current code block. (Similar to this question, but more generic) 回答1: I'm going to just copy and paste the entire content of "Searching with / and ?" (within a visual selection) from the Vim Tips Wiki. In visual mode, / and ? will

问题 Is there a command which shows what was the last command in normal mode? Suppose I accidently hit random key and got some unexpected result. Sure I can undo it, but could I reveal what key was pressed and how it was interpreted? 回答1: Hit the colon ( : ) and then use the up arrow to start going back through previous commands. You can use the up/down arrows too to move around the list. 回答2: q: will show you command history in Vim. q/ will show you history of searches 回答3: The text from the last

Traversing text in Insert mode

阅读更多关于 Traversing text in Insert mode

While in Insert Mode in Vim, is there any way to traverse the text moving some characters forward and backward other than using the arrow keys? If I press h , j , k and l while in Insert mode, the actual characters are printed on screen instead of moving through the text. The way I'm doing it at the moment is having to resort to Ctrl + [ ( Esc ) and traversing the text then; but obviously that is not productive. P Shved You seem to misuse vim, but that's likely due to not being very familiar with it. The right way is to press Esc , go where you want to do a small correction, fix it, go back
