Emacs repeat string n times

自古美人都是妖i 提交于 2019-12-02 17:13:21
I'm learning the basics of navigating/editing in Emacs and I'm curious how one could accomplish the following task: Repeat the string 'bla ' n times in normal text editing mode. Let's say I want to repeat it five times to generate 'bla bla bla bla bla '. I tried... C-u 5 bla ...but the command executes after the 'b' is entered, and I only get 'bbbbb'. I'm sure there's some basic command that can help me here...would somebody be kind enough to enlighten me :)? One way is via a keyboard macro : C-x ( bla C-x ) C-u 4 C-x e You can also just insert the repeat count before the macro termination: C

Javascript syntax highlighting in vim

旧时模样 提交于 2019-12-02 15:24:26
Has anyone else found VIM's syntax highlighting of Javascript sub-optimal? I'm finding that sometimes I need to scroll around in order to get the syntax highlighting adjusted, as sometimes it mysteriously drops all highlighting. Are there any work-arounds or ways to fix this? I'm using vim 7.1. You might like to try this improved Javascript syntax highlighter rather than the one that ships with VIMRUNTIME. Well, I've modified Yi Zhao's Javascript Syntax , and added Ajax Keywords support, also highlight DOM Methods and others. Here it is, it is far from being perfect as I'm still new to Vim,

“Find next” in vim

有些话、适合烂在心里 提交于 2019-12-02 13:46:51
To search forward in vim for cake , I'd type /cake , but the cursor jumps to the first match when I press return. Is there a vim command analogous to "find next"? Xavier T. It is n for next and N for previous. And if you use reverse search with ? (e.g ?cake ) instead of / , it is the other way round. If it is installed on your system, you should try to run vimtutor command from your terminal, which will start a tutorial of the basic Vim commands. Rob Wells advice about * and # is also very pertinent. Rob Wells The most useful shortcut in vim, IMHO, is the * key. Put the cursor on a word and

jqGrid - How to edit and save multiple rows at once?

旧巷老猫 提交于 2019-12-01 12:14:59
We are aware of how to allow users to edit multiple jqGrid rows - but how would one have a single save button that saved all edited rows? We do it manually (not with a jqGrid feature). We have a custom formatter which draws editors and we put a <form> tag around the whole grid, with a submit button at the bottom. 来源: https://stackoverflow.com/questions/3738778/jqgrid-how-to-edit-and-save-multiple-rows-at-once

Prevent two users from editing the same data

邮差的信 提交于 2019-12-01 07:37:39
I have seen a feature in different web applications including Wordpress (not sure?) that warns a user if he/she opens an article/post/page/whatever from the database, while someone else is editing the same data simultaneously. I would like to implement the same feature in my own application and I have given this a bit of thought. Is the following example a good practice on how to do this? It goes a little something like this: 1) User A enters a the editing page for the mysterious article X. The database table Events is queried to make sure that no one else is editing the same page for the

Can I specify which Columns are editable in a WPF DataGrid?

浪尽此生 提交于 2019-11-30 15:26:18
问题 I have a WPF 4.0 DataGrid with AutoGenerated columns. I would like to only allow the user to edit the first column. Is there an easy way of doing this? I was trying to add a DataGridCell style and set it's editing ability based on either ColumnName (1st column always has the same name) or ColumnIndex, however I cannot figure out the correct XAML for this, or even if it is possible. 回答1: The below sample does the trick for one or more columns private void Grid_AutoGeneratingColumn(object

UITableView delete button not appearing

若如初见. 提交于 2019-11-30 09:29:55
问题 When I press the edit button I get the round delete icon to the left of the item. When I press the delete icon in the cell it 'turns' but the delete button does not show up so my commitEditingStyle never gets called because I have no delete button to press. Just for fun...I change the cell to Insert I get the plus icon...I press it and commitEditingStyle is called. I do not understand why I am not getting the delete button. I have a UIViewController that I am showing in a popover. I am adding

Stop PHPStorm from cutting/copying the entire line if nothing is selected

我们两清 提交于 2019-11-30 09:09:15
If I set the caret on a line and accidentally press Ctrl X or Ctrl C instead of Ctrl S , then the entire line is cut/copied, since there is no selection. This can be very annoying, and can often times destroy code in the clipboard which I wanted to paste. I'd expect nothing to happen if nothing is selected. How can this be turned off? Go to Registry screen: Help | Find Action... and search for registry there Once there -- find and activate editor.skip.copy.and.cut.for.empty.selection entry. 来源: https://stackoverflow.com/questions/27697758/stop-phpstorm-from-cutting-copying-the-entire-line-if

How do I edit and delete data in Django?
