I'm back
Hello all, I just wanted to let you know that I am back on the vim and vim-dev mailinglists. I won't have time to write many mails, but my colleagues at work started to ask me a lot of questions about vim when they found out that I wrote syn on and colorscheme koehler in root's vimrc of all servers so I thought it might be good to get back to the old habit of learning by reading the solutions of fellow vim users to the questions of other vim users. :-) I might as well throw in a few mails, but as I only read my private mail on the weekends there will be only a few mails from me...

Re: How to modify code so that only one space is between two characters or words?
[...] You could use a Search/Replace on the full text. This does end up modifying your base text, so be sure to only use it on modifiable buffers.

replace word from buffer
Hi, is there a way to do this more effectively?

Despite the fact, that -- without the yank-ring script -- you have to keep an eye on what is in what buffer, it would be more effective if one could do the following: ywyank replacement word /word find word (word) to be replaced cwchange word under cursor with that in buffer I know, that cw is another command, which is wrong in this case...I only needed a name for what I want to do and cw keeps track of the length of the replaced word and the replacement.

RE: copy pasting HTML code into vim
Let's say I open up a webpage, select some text and paste it into vim. Then all I see in vim is the text I see on the browser. While this is OK most of the times, sometimes I wish there is a way to paste the actual HTML code directly into the vim. Selecting view source of the webpage and then copy pasting into vim will work. But it is very cumbersome and time consuming. So this is not an option for me. Wouldn't think so. That's a function of the browser (what yanks the text into the buffer to begin with), and not 'vim' (which only gets what's handed to it). Were you to put the yanked text to 'notepad', 'textpad', etc., it'd be the same thing, just the plain unadorned text. GIGO (garbage in, garbage out). Fwiw, just use shortcuts to get to the source, whether altvs/alt, ^S, ^U, whatever your particular browser needs to get there.

RE: copy pasting HTML code into vim
This is a clipboard thing - windows for instance copies stuff in many forms and pastes it in the form most acceptable to the receiving app - plaintext for vim, html/rtf for a word processor... Dunno if there's a way for vim to say gimme html. I would try looking at your browser. In firefox, for example, you can select a source editor in about:config Set view_source.editor.external to true, and view_source.editor.path to your path to the vim binary. Then when you do view source, it'll popup in vim. You can /search for the text you wanted, yank it with its enclosing html, and paste it into a split buffer. You can do all this without having to use the mouse (assuming you have a view source hotkey), so I don't think it's too cumbersome. I know in lynx you can select a source editor as well, although I don't recall how right now, and probably in all other major browsers as well. *tim* -Original Message- From: news [mailto:[EMAIL PROTECTED] On Behalf Of Kamaraju S Kusumanchi Sent: Thursday, April 05, 2007 11:15 PM To: vim@vim.org Subject: copy pasting HTML code into vim Let's say I open up a webpage, select some text and paste it into vim.

While I don't know what went hooey on your machine, a couple ideas:
1) turn off syntax highlighting. Vim seems to wheeze when
syntax-highlighting long lines.
2) To split the line like you describe, you might try
:s/.\{72}/\r/g
(adjust the 72 for the number of characters you want on each
line). I don't know if it's any faster, but it can hardly be
worse ;)
3) you might try cranking back your 'undolevels'. I'm not sure
it would help a great deal, but if the other two don't have a
deep impact, it might help.

Hello Meino the vim killer Cramer, I tried your scenario. You need to add 'set ul=-1' to disable undoes, and 'set lz' to disable excess redraws. Even then, vim goes rather slow at this task. Indeed, vim grows to 1000MB vm/rss size size in matter of one minute without ul=-1 (, and growing very fast. ) To make editing of 2MB-long line manageable, I did: vim -u NONE file :set ul=-1 : disable undos :set lz NOte that 2MB is already large file. You are now in the area where you want take large file precautions wrt to performance. This makes vim stay stable in memory size (although still rather large, 632mb). But it's still slow at splitting 2mb-long lines. It took vim ~4 minutes to split ~100 lines. So, for a whole 2mb data, it will take vim about 2 hours. You better try this kind of task with perl or C. Or just add sensible newlines when generating your data. Yakov BTW your disk size is irrelevant. What is relevant is your RAM size and swap size.
Re: Vim freezes system ?!
The problem I have with my kind of splitting a line is not that it does not work -- it is the deadly side effect it caused. My opinion is, that it should not be possible to kill a system (...too big words, I know, but...) by simply submitting a sub-optimal command to a text editor. As you killed it, there's no way to know if the process would have been seen to completion. *nix-like OSes shouldn't allow you to drag the system to its knees without affording other processes (such as X) timeslices of the CPU. You didn't mention how much memory your system has, but the specs are otherwise well within tolerances. I suspect you may have found a pessimal (opposite of optimal) solution to your problem and that Vim+Gentoo would have happily carried out your instructions, even if it involved heaps of memory and hours of CPU burn. Additionally, as your line(s) got shorter, I suspect the time to process each subsequent line would diminish. So no, in general, it shouldn't kill a system, but it sounded like your system was doing exactly what you asked of it. X responded (albeit slowly) and you were able to get to a console and start bustin' heads. That's kudos to an OS that can be functional even under heavy load. It also sounded like Vim was doing what you asked of it (though perhaps not optimally), which caused it chug on the CPU. It would be akin to writing a Python program that spun in a tight infinite loop: while True: pass and dragged your system to its knees...it's not Python's problem per-se, as it's your script/commands that are the problem.

Aha, so you didn't try to edit a file. You tried to find a scenario to push vim beyond it's and your system's memory capacities. OK, you succeeded. Yakov

Is this expected behaviour ? Yakov

Even the mouse pointer was nearly unmoveable... After heavily and constantly trying I managed to kill the X-session and to 'killall -9 vim' from the console to get back my computer. I am using an up-to-date version of Gentoo and vim (not gvim). My system runs an AMD 64 X2 3800+ CPU and uses a Seagate 200GB harddisk (dma enabled). It needs a lot of load to bring the system to its knees. May be it was wrong what I did in the sense of there are better UNIX tools to reformat such a file or better commands in vim to accomplish this,... ...but in a critical moment it may be that I would have lost my work (other open applikations) due to the need of killing X. Keep editing! ;) mcc Try Ctrl-Alt-F2 to get to a text console without killing X. Then enter a login name and password. On Linux, you normally have six text consoles just waiting there for you to log in, even while X is running. Ctrl-Alt-F1 (/dev/tty1) normally has the last page of your boot sequence log, so you may (or may not, after all) want to leave that one in peace. Ctrl-Alt-F2 to Ctrl-Alt-F6 are the other five (/dev/tty2 to /dev/tty6). /dev/tty7 is what the X server video output goes to (and, IIUC, where its keyboard input comes from), so you hit Ctrl-Alt-F7 to go back to X after having used a text terminal. (The X server display input is normally called :0 ). There are more possible terminals (/dev/tty8 to /dev/tty12, maybe), but since there is no getty (or, more often, mingetty) program listening there, you can't log into them. You _can_, if you wish, redirect a program's sysout and/or syserr to them, and look at the latest page of output by means of the appropriate Ctrl-Alt-Fn keychord. For instance, /dev/tty10 (Ctrl-Alt-F10) is usually the syslog listing, at least in the Linux distros that I use. Best regards, Tony. -- hundred-and-one symptoms of being an internet addict: 164.

Yakov I have maxmapdepth=1000 maxmempattern=1000 maxmem=249 maxmemtot=249 which strikes me as strange (even though the last three are in KB) since I never set them and the docs say maxmem is usually at least 256 and maxmemtot at least 2048.

I'm back
Hello all, I just wanted to let you know that I am back on the vim and vim-dev mailinglists. I won't have time to write many mails, but my colleagues at work started to ask me a lot of questions about vim when they found out that I wrote syn on and colorscheme koehler in root's vimrc of all servers so I thought it might be good to get back to the old habit of learning by reading the solutions of fellow vim users to the questions of other vim users. :-) I might as well throw in a few mails, but as I only read my private mail on the weekends there will be only a few mails from me...
