How to replace text between quotes in vi

2019-01-21 03:19发布

问题:

Say I have this line of code:

$query = "SELECT * FROM table";

Is there a command in vi/vim which can instantly delete everything between quotes and position the cursor between them so I can start typing?

回答1:

Use ci", which means: change what inside the double quotes.

You can also manipulate other text objects in a similar way, e.g.:

  • ci' - change inside the single quotes
  • ciw - change inside a word
  • ci( - change inside parentheses
  • dit - delete inside an HTML tag, etc.

More about different vim text objects here.



回答2:

You can select between quotes and then delete (d), change (c) etc. using

vi"

Similarly, you can substitute braces, brackets, XML elements etc. thus:

vi(
vi{
vit

or to simply change/delete, do the corresponding di", ci" etc. Substituting a for i will encompassing the surrounding elements (so you mark or change the brackets and contents, for example)



回答3:

From already inside the quotes you can do

di"

Read it as delete inside "

I've made a plugin vim-textobj-quotes: https://github.com/beloglazov/vim-textobj-quotes

It provides text objects for the closest pairs of quotes of any type and supports quotes spanning multiple lines. Using only iq or aq it allows you to operate on the content of single ('), double ("), or back (`) quotes that currently surround the cursor, are in front of the cursor, or behind (in that order of preference). In other words, it jumps forward or backwards when needed to reach the quotes.

It's easier to understand by looking at examples (the cursor is shown with |):

  1. Before: foo '1, |2, 3' bar; after pressing diq: foo '|' bar
  2. Before: foo| '1, 2, 3' bar; after pressing diq: foo '|' bar
  3. Before: foo '1, 2, 3' |bar; after pressing diq: foo '|' bar
  4. Before: foo '1, |2, 3' bar; after pressing daq: foo | bar
  5. Before: foo| '1, 2, 3' bar; after pressing daq: foo | bar
  6. Before: foo '1, 2, 3' |bar; after pressing daq: foo | bar

The examples above are given for single quotes, the plugin works exactly the same way for double (") and back (`) quotes.

You can also use any other operators: ciq, diq, yiq, viq, etc.

Please have a look at the github page linked above for more details.

An addition to Brian's answer, you can also p(paste) and y(yank) the new value, so if you want to replace the value inside quotes with another value, you could do yi" on the selection that you want to copy, vi" to select the area that you want to replace and then just p to properly replace the value.
