| − | Francky Teston -- please try your idea on the Feb28 note above's block of abcabcs... . Be sure to use ctrl-v to highlight the second block of cab, and apply s/cab/CAB/ as shown in the example above. You'll see that your idea capitalizes the *first* column of cab, not the *second*. That's because the visual-block nature is ignored by the substitute command; it gets applied on a linewise basis. Vim 7.0 does not change this behavior. vis.vim allows one to select exactly where the substitute is to be applied on a visual block basis. |

Revision as of 10:32, 30 October 2007
created March 28, 2001 · complexity intermediate · author Chip Campbell · version 5.7
If you'd like to apply a substitute, or even any ex command, to a visual-block selected text region (ctrl-v and move), then you'll want Stefan Roemer's http://www.erols.com/astronaut/vim/vimscript/vis.vim
Just source it in, and then press ":B". On the command line you'll see
:'<,'>BCtrl-V
Just continue with the substitute or whatever...
:'<,'>B s/abc/ABC/g
and the substitute will be applied to just that block of text!
Example: Ctrl-V Select..........|......Type ..................just the central.......|......:B s/abc/ABC/g ..................four "abc"s.................| ..................---------............|...------------- ..................abcabcabcabc............|......abcabcabcabc ..................abcabcabcabc............|......abcABCABCabc ..................abcabcabcabc............|......abcABCABCabc ..................abcabcabcabc............|......abcabcabcabc (dots inserted to retain tabular format)
Comments
Sorry about the "Ctrl-V" in :'<,'>BCtrl-V, it shouldn't be there. Also I tried to get the dots to line up, but proportional fonts won out.
I fear I may not have conveyed the idea properly. It's not referring merely to a block of lines but to a visual-block (ie. a subset of the characters) and restricting the substitute to refer only to that visual block.
I want to convert just the some of the central "cab" strings to CAB; use ctrl-v and motion (hjkl or cursor keys) to select the "cab" strings to be transformed via a visual-block selection:
to ----> abcabcabcabcabc abcabcabcabcabc abcabcabcabcabc abcabCABcabcabc abcabcabcabcabc abcabCABcabcabc abcabcabcabcabc abcabCABcabcabc abcabcabcabcabc abcabcabcabcabc
This operation has nothing much to do with converting a line to a vertical list. Often it is used to change a variable:
to ---->
printf("...", printf("...",
abc[0],def[0],ghi[0], abc[0],DEF[0],ghi[0], abc[1],def[1],ghi[1], abc[1],DEF[1],ghi[1], abc[2],def[2],ghi[2], abc[2],DEF[2],ghi[2], abc[3],def[3],ghi[3], abc[3],DEF[3],ghi[3],
One could break this on the commas, [range]s/def/DEF/, and rejoin, but that's a lot more work and less intuitive than simply using ctrl-v to select a visual block and doing the substitute just on that visual block.
Vis.vim has been improved as of 6/19/2002 -- it is now immune to tabs and is considerably faster. Its a complete internal re-write, although its interface has been retained.
