Ahh what a day. I’ve spent most of my time ether on the forums or in my beloved editor of choice (vim). I desided for some odd reason to rewrite my vim resource files. I’ve more or less completed my ~/.vimrc file and will worry about my ~/.gimvrc file later. Really I rarly use the GUI off win32. I basically like using vim in konsole because I can quickly step in and out of editing, ether by forcing vim into the background (control+z, type fg to return to it). Yet because cmd.exe is the worst terminal I have ever used, poor if any support for cut, copy, and paste. Ignores the mouse for the most part and Windows has the tab completion of a fart in the wind. I’m kinda getting used to zsh’s after using tcsh so much hehe.

Heres my vimrc file so far, edited for a few things. The syntax is about as simple as a shell script or “vim script” but the ” double quote works like the # and // comments in most languages. White space it doesn’t care for but it does care about line endings. Since I share most things between Windows XP, PC/Free BSD, and GNU/Linux + several computers I have to be portable in many ways. I started the file on Windows with my file format set for Win/DOS end of lines (:set ffs=dos), vim detects it and uses whats there. I usually set mine as “ffs=dos,unix,mac” so I don’t have to convert my files End of Lines (EoL) when I send some one a text file. If I use UNIX eols theres no carriage returns in Notepad, it’s too dumb to figure it out unlike many many other editors. Sad through is you can always count on some one to have notepad or a simular editor. Gnomes editor and KDE’s KWrite are actually rather nice though. When I tried to run my now complete vimrc on PC-BSD I got a zillion errors and I new I didn’t screw it up that bad, infact only one entry was wrong. I quickly figured out it must have been the line feeds, the fact that I had just setup a keybind to strip off the pesky ^M’s you get in some files helped hehe. I couldn’t find any quick ways to convert the EOLs so I looked them up in Wikipeda and found a way to do it with pearl, I now have a pdos2unix and punix2dos script to do the job when given an input file name and an output file name.

I’ve been told customizing Vim can be bad b/c of having to work with standard vim/vi but I’m a fruit -> If I want Vim I call vim and if I want Vi I call vi. FreeBSD uses nvi for vi, not vim like some GNU/Linuxes do. If some Linux Distro doesn’t make vim start as vi compatible without special changes it’s not my problem. I learned to use vim with just the example vimrc file. After that using Vi was easy after an hour or two. I also remember which I’m using by the fact that I call vi as vi and vim as vim + the status line I keep around.

Some changes I plan, if it’s starting with the GUI I’ll have it set it so I can right click on miss spelled words and correct them. you can move the cursor to the word and press z= for a list of corrections, and use ]s and [s to search forward/back. Some times I just scroll with the mouse when proof reading so this helps. You can do a :set “mousemodel=popup_setpos” to get it after you turn on spell checking. I want to set it up so I can quickly convert a files format between DOS and UNIX via F11 and F12, should be possible.

I’ve downloaded a few things from http://www.vim.org/scripts/ that I want to toy with. One was a pack of 140 themes for gvim gotta sort that hehee. Another was a Matrix screen saver. It’s pretty nice if you speed it up but on my system it makes me use like 50~60% CPU judging by GKrellm2 my favorite GTK Krell system monitoring app.

One of the reasons I love vim very much is it’s very relaxing to us. Since I play games often as I can get a good tactical one /w my team mates. I do plenty of running. Once the tangos know your there you gotta get moving quickly (Dynamic). So in the intertests of moving as fast as is safe and doing proper B and CB entries (Bang & Breach Bang clear). I have my pinky jutted out to hold shift many times. B/C Usually I don’t run all the time, I try to sneak about unless I plan on being Dynamic. So that and using my pinky to make capital letters puts alot of strain on my, now couple that with Escape Meta Alt Control Shift (EMACS) style editing. When I use my pinky to deal with capslock (hate that key), shift, control, z, and Windows. It’s nice not to have to strain my fingers or wrists. I find using vim very comfortable for long edits. It’s also so dang effective that I can’t stand many other editors. Its like the speed and power of Vi/Vim ruins you for other editors once you learn it. I don’t claim to be no Vim Master or any thing but to me its gotta be the worlds greatest editor. Vi is in the top 10 in my book but Vim >= #1 xD

The only bad thinkg is some times I press # instead of $. The $ key moves to end of line in normal/visual modes. While the * and # keys searches forward and backwards for the word under the cursor. One thing I’m looking at is a C Refernce that can be ran in Vim, might help me write files on Win32 again. Usually I prefer BSD for doing C work because I can quickly look up a routine via the system manual. After all Unix was written in C and so is largly FreeBSD and I’d reckon most of GNU/Linux which is infact made up of many languages afaik.

Vi, Macs, and Shells

I’ve so got to get or make a Vim plug in or some thing for this.

So far I’ve come to a cross roads, I can keep my editor or I can become more Emacs compatible. On Windows I use PuTTY for a ssh client. I don’t know what the terminal emulator is but it sucks. When working on Vectra I effectively have no insert/home keys e.t.c. or Numpad which is bad because I’m accustomed to using the home and end keys in my line editing. This means ether live with only cursor keys and backspace for line editing or relearn the Emacs navigation commands. Control+key is used, b for back one char, f for forward one char. p for previous command (up) and N for Next command (down). e for end of line while a is used for end and home key replacements. Using the meta key (generally alt) turns this up a notch and uses larger units such as forward a word instead of a char. I’m used to using control+u and control+w in line editing – I don’t know if control+w has effect in Emacs but control+u doesn’t.

Needless to say I don’t like Emacs ! I used XEmacs as my editor at first but I fell in love with Vim after I started getting into shell use. You could say learning the shell helped me learn Vim and vice versa. I didn’t like vim at first and I’m only now starting to use gvim off windows (konsole is better then cmd.exe). I’m very used to Vim so I am also used to Vi. My vimrc file makes it easier to use but since Vectra is very light on the software I didn’t install vim. Vi is good enough and ee for when I’m just pissed.

Vim/Vi is very simple to use once you get the hang of it, Emacs is just wrist strain. So now I ask my self the question: What about Vi editing mode? The Bourne and Korn shells support it as does the Z shell AFAIK. However I use tcsh which does not. So if I want to use this editing mode that means use another shell. Vectra only has sh and tcsh. Being FreeBSD the csh is actually tcsh but not like how bash is commonly GNU/Linuxes sh. FreeBSD uses ash as s, a very light Bourne shell clone. I could install any other shell I want really and a ruby shell would be kind of cool if it could fuse an interactive shell, scripting and ruby into one package. The problem is if I get used to vi line editing in a shell I’ll be ruined for any other shell !. I’ve yet to decide but to be honest with the Vi editing mode I think sh is livable. It nets the use of cursor keys and command history.

nvi/Vim is very simple. Vi is a modal editor, if you press escape you are in a command mode, if you press “i” or insert you are in insert mode and it’s like most text editors. You litterly change the entire keyboard into/out of modes. In insert mode your keys always insert chars, most consoles let you use the arrow keys, home/end/delete/backspace like normal. In normal mode which can be reached by pressing escape. Every key stroke is a command or switches to other modes. You can move the cursor with the h,j,k,and l keys. The h and l keys move left and right while the j and k keys move down and up. I’ve heard that Bill Joys console had arrow keys on these so that’s probably why they are used this way. It was a little weird at first but now I’m getting used to it. I’ve generally used the cursors.You can delete a char using the “x” key.

You can delete directionally by prefixing a movement key with d. So dh and dl deletes one char to the left or right. Pressing dj or dk will delete the current line and the line below or above. To kill the whole line use dd. You can repeat commands by appending a number, example: dd3 will delete 3 lines. You can move to the start or end of line by pressing ^ and $ this also works with d. You might notice ^ and $ from some studies in regular expressions – I do from a bit of sed/grep/awk learning. You can move forward and back a word at a time with the w and b keys. Much faster then control+key combo and easier on the wrists IMHO! Pressing i puts you into insert mode to enter text, pressing v puts you in visual mode. Escape will bring you back to normal mode. I never used visual mode very much at first but now I find it useful. In visual mode most normal mode commands for movement work the same. Yet when you move the cursor you always highlight or “select” text. You can copy it or “yank” it with the y command and put or “paste” it with the p command. If you want to cut it use the c command. Usually after a cut I think Vim puts you in insert. Pressing : gives you a little command line.

Here you can enter commands but internal and external, set options and more. To edit a file type e /file/name after pressing : for speed I bound ; to do the same as : in my vimrc. To save it’s :w also know as write ! To quit it’s :q note that you press the ” : ” you don’t type it as part of the command. You can override it by suffixing it with a !. Example: force a quit by doing a :q!

We can run shell commands by prefixing them with a “!” like this :!ls ~/Documents. File name completion works and a UNIX shell is better at it then cmd.exe (vim is very portable). Vim might seem a bit awkward at first but once your used to it it’s very fast and effeienct. TO get help type :help to get context sensitive help try :help topic_or_cmd

Using vi line editing in a shell works the same was using Vi only you start off in insert mode instead of normal mode. I haven’t decided what to do yet.

Ya know whats funny…. I started out to write a short post about my feelings but I end up trying to knock out a Vi/Vim intro before my batteries run out.

All roads lead to Vi !!!
