Tip: #193 - Insert current filename

Created: January 7, 2002 16:00 Complexity: basic Author: Steve Downing <sweb--AT--REMOVE_THIS_TO_REPLY.helmsdeep.net Version: 5.7 Karma: 37/23 Imported from: Tip#193

I found this one good for when I was starting to learn Java, it simply inserts the current filename, at the cursor position, when you are in insert mode. Honestly, its a mish-mash of some other tips I found here, but I thought it might be useful.

:inoremap \fn <C-R>=expand("%:t:r")<CR> 

Enjoy!

I often use <C-R>% when in insert mode... It does the same thing, except you also get your file extension.

Cool tip. I find myself needing to do this whenever I create a new Java file.

The % variable for file name is also helpful from the command prompt (: at the bottom). I use it for checking the syntax of source code before using it. For example, if I am editing a perl module, this is helpful:

:w|!perl -c % 

This saves the file (w), and executes perl -c on the current file which runs a syntax check.

Yet another useful % application: suppose your source-files reside in a '.../src' (or '...\src') directory. Now this line will insert the package-structure of you current Java-file at the cursor position:

:inoremap \jip <C-R>=substitute(substitute(expand("%:p:h"), "^.*[/\\\\]src[/\\\\]", "", ""), "[/\\\\]", ".", "g")<CR>

(Four backslashes because you need to escape them twice.)

Then use single quotes instead of double quotes: '^.*[/\\]src[/\\]'

BTW, matchstr(expand("%:p:h"), '^.*[/\\]src[/\\]\zs.*') is simplier
