[ #237 ] Vim Makefile tabs Permalink

Makefile, Vim Added about three weeks ago

If, like me, you have your vim setup to do 4-space tabs, you will have a problem when you are editing Makefiles. Makefiles need real \t tabs. There are two ways to deal with this.

The first is manual: instead of pressing the tab key, press ctrl-v ctrl-i

The second way is using a vim comment hint like so:

# vim: noexpandtabs

... somewhere in your file. With this second method you can now simply press the tab key to get real tabs.

[ #234 ] Vim comment hints Permalink

Vim, Python Added about three weeks ago

If you need vim to interpret a file in a specific way (or set some values for a specific file only), you can put comment hints in the file.

For example, if you have a Python file that doesn't have a .py extension and also doesn't have a #! line indicating that it is indeed Python, then vim will not turn on the correct syntax highlighting for your file (because it thinks it is just plain text.) To force Python syntax highlighting, place a comment hint at the bottom of your file like this:

def eggs():
    pass
# vim: syntax=python

[ #227 ] Tell gvim to save and quit... remotely Permalink

Vim Added about a month ago

If you have a gvim session open on your desktop, and you later have to ssh in to your desktop to edit the same file, you'll get the familiar message that the file you are editing is open elsewhere and you can save, abort, etc etc.

Do this to safely save and quit that session first:

$ vim --serverlist
GVIM
$ vim --servername GVIM --remote-send '<C-\><C-N>:wqa<CR>'

... and now you can open the file up for editing safely from your ssh session.

[ #166 ] Making Vim Save on Ctrl-S Permalink

Vim Added less than a year ago and last edited less than a year ago

Add this to your ~/.vimrc file:

if has("gui_running")
    imap <c-s> <Esc><c-s>
    map <silent> <C-S> :if expand("%") == ""<CR>:browse confirm w<CR>:else<CR>:confirm w<CR>:endif<CR>
endif

[ #165 ] Moving Vim Tabs Permalink

Vim Added less than a year ago

It's easy - on the current tab that you want in a different spot, just execute:

:tabm num

... where num is the zero-indexed position you want to move it to.

[ #163 ] Vim Sessions Permalink

Vim Added less than a year ago

When using vim an interesting idea is to save a session file for each ticket you are working on.

Say you are working on TICKET-881, and you have the 8 files relevant to this ticket open in tabs, you firstly save your session:

:mksession TICKET-881.vim

Then when you need to go back to work on that ticket at a later stage, start up with that session like so:

$ gvim -S TICKET-881.vim

... and all your tabs, environment, cursor positions etc will be like you left them. This can help to reduce the pain of context-switching between tickets and trying to remember exactly what files you were editing at the time.

[ #141 ] Using perltidy from vim Permalink

Vim, Perl Added less than a year ago

Make sure your .perltidyrc is setup, then just:

:%!perltidy -q

... and voilà - tidy source.

[ #139 ] Vim - Refresh Bad Colours Permalink

Vim Added less than a year ago

Sometimes the syntax highlighter in vim gets confused with complicated syntax - and colours might go wrong for a string or comment etc.

You can force vim to refresh the syntax highlighting by pressing Ctrl-l (that's the letter L) - just like how you quickly clear the screen in terminals.
