Programming

I currently work with an SVN checkout which tracks a separate GIT checkout (for reasons of managerial short-sightedness). When I update my git checkout, I find that the SVN checkout does not like the fact that files deleted by the git update have effectively been removed from the SVN checkout without the use of svn rm. Consequently, it is impossible to commit the updated checkout into the SVN repository.

Earlier today, I found myself working with an SVN checkout. As it happened, the repository that the files had been checked out from was no longer responding and upon enquiry, I found out that it had been moved to a different URL. Now, while I could have just as easily created an entirely different checkout of the files using the new URL, considering the local customisations, I looked to see if I could just do something like a live switch. As I found out after some mucking about, switch is certainly the operative word.

I'm not sure whether it was something I did, something that the Vim developers did, or an anomaly with the Windows 7 binary, but I could no longer see the line number and cursor position tracker in the bottom right of my interface. Looking at the menus, I could find nothing. I could turn on a line number prefix for each bleeding line, but this is not what I was after.

Some people like to indent their code using TABs. I used to like doing this. I still think that it's a good idea. But circumstances have dictated for the past several years that I need to indent using spaces instead. My favourite command-line editor in Linux and text editor in Windows is VIM / Gvim (where Gvim is basically Vim with a GUI). To configure this editor to override its default and use spaces instead of TABs for indentation, perform the following steps:

If you ever run into a git-receive-pack not permitted error when using Git, chances are that it's a configuration issue on your end. In my case, I had cloned the repository using via https (which required authentication). However, pushing failed with the aforementioned error. This was due to the fact that I was only allowed to push via SSH. Therefore, once I changed the protocol in the configuration for my checkout, all was well again.

I had to do a clean install of Eclipse today and found myself stuck with a dodgy plug-in (subversive). However, when I went to the Help menu, I did not find any option to uninstall software. IIRC, there was something along the lines of Manage configuration here where you could go to makes changes and uninstall plug-ins.

I ran into an error message today that only specified the character number in a configuration file without making any reference to the line number. Rather odd. In any case, since Vim (and my usual preference, GVim) is an excellent editor, I expected this to be a cinch. Unfortunately, a few minutes of head-scratching later, I was still quite clueless as to how to accomplish this seemingly routine task.

I do know that typing:
:1000
will move the cursor to the 1000th line in the file.

When a file has no line-breaks and is just one single line, navigating line by line is obviously not an option. Some editors wrap the text and treat each pseudo-line as a separate element and allow us to scroll through them. Others don't. Vim, by default doesn't.

Or to be more precise, Vim (and GVim) do not allow us to scroll through such files using the arrow keys. Instead, the following short-cuts do the business:

Scroll up: g, k / g, up
Scroll down: g, j / g, down
Beginning of the line: g, ^ [i.e. g, SHIFT + 6 on a keyboard with a US layout]

Shared editing is very useful for debugging / walk-throughs etc., and the Real-time shared editing plug-in, which is a part of the Eclipse communication Framework Project is nifty beyond expectations.
