Indent/Format the whole buffer in Emacs

Neil Wightman — Mon, 08 Feb 2010 09:48:12 +0000

I have had an indent-buffer command like this for some time, which formats the whole current buffer. I used it for java, c++, css, html, xml and lisp.

(defun indent-buffer ()
    "Indent the current buffer"
    (interactive)
    (save-excursion (indent-region (point-min) (point-max) nil))
)

I found the above function at http://www.emacswiki.org/cgi-bin/wiki/ReformatBuffer

Recently I noticed that it was leaving tabs in (which I hate) and trailing spaces. It was simply just indenting the buffer.

After some more searching today I found the untabify command and I created the following commands. Mainly because I expected the command to be called something like tab-???

(defun untabify-buffer ()
    "Untabify current buffer"
    (interactive)
    (save-excursion (untabify (point-min) (point-max)))
)
 
(defun tab-to-spaces ()
    "Convert tab to spaces"
    (interactive)
    (save-excursion (untabify (point-min) (point-max)))
)

I then found this page, http://emacsblog.org/2007/01/17/indent-whole-buffer/ which has the best indent/format buffer function.

(defun indent-buffer-2 ()
    "Indent the buffer 2"
    (interactive)
    (save-excursion
        (delete-trailing-whitespace)
        (indent-region (point-min) (point-max) nil)
        (untabify (point-min) (point-max))
    )
)

Home and End key with rxvt

Neil Wightman — Tue, 31 Mar 2009 09:18:38 +0000

I use cygwins rxvt at work and have had problems with the End and Home key not working.

I also had the same issue at home using rxvt-unicode

on gentoo.

After lots of search last night I finally found the fix for urxvt.

Simply add this to your ~/.inputrc file

# home and end keys for rxvt
"\e[7~":beginning-of-line
"\e[8~":end-of-line

I then tried this at work this morning and found it works on cygwins rxvt too.

My emacs startup script for cygwin

Neil Wightman — Tue, 24 Mar 2009 10:19:07 +0000

This is my emacs script for cygwin. It runs the Windows Emacs version and runs just 1 instance of emacs in most cases.

Typing emacs on its own simply starts a new version of emacs.

Type emacs and a file will try to open the document in a running version if its started else it will start emacs.

#!/bin/bash
 
if [ -z $1 ]
then
    d:/apps/emacs-22.2/bin/emacs.exe
else
    d:/apps/emacs-22.2/bin/emacsclient.exe -n \
    -a d:/apps/emacs-22.2/bin/emacs.exe $@ \

SSH and rsync through a socks proxy

Neil Wightman — Wed, 17 Dec 2008 12:17:51 +0000

I’ve been using Dropbox for quite some time to transfer files from work to my home PCs. This is worked well for months, but I finally filled my dropbox account.

watch life less ordinary a online As I have a linux box at work and a linux box at home I decided to try and setup some simply one way mirroring system. I.e. mirror documents from work to my home PC.

I looked at using unison, which I used to mirror many other directories but I couldnt get it to connect out from my work PC. It appears to lack socks support. I know I could use ssh port forwarding to sync via sockets but this would be more complicated.

I decided to use rsync

via ssh.

There was one main issue though, I needed to get ssh to work over our proxies. We have a few http proxies and 1 socks proxy. The http proxies will not connect to arbitrary ports so I ended up using the socks server.

I knew the socks server worked as I’ve used it with putty watch hannah montana the movie online for years, so I just needed to figure out how to setup ssh to use it.

After lots of search and finding articles regarding port forwarding and nothing about using a socks proxy I found 1 good article.

I use gentoo linux so I emerged net-misc/connect which supports socks servers.

emerge -auv net-misc/connect

Once I had the connect utility installed I needed to edit my ssh config file. I only have 1 user configured on my linux box at work so I edited the ~/.ssh/config file.

This is what I added

Host stokebloke.com
ProxyCommand connect -S user@socks-server:1080 %h %p

Host www.stokebloke.com
ProxyCommand connect -S user@socks-server:1080 %h %p

Host homebox.homelinux.net
ProxyCommand connect -S user@socks-server:1080 %h %p

You can also do the same thing with cygwin too. Instead of using connect program its called connect-proxy in the network section of the cygwin installer.

After I got this far I needed to configure rsync to work via this ssh connection which, it turns out, is very simple.

rsync --progress -avrz -e ssh src_dir/ user@homebox.homelinux.net:~/dest_dir/

This results in the src_dir existing inside the dest_dir.

Fluxbox 1.0.0 for cygwin

Neil Wightman — Fri, 02 May 2008 08:44:15 +0000

I have built fluxbox for cygwin and tested it on 2 PCs now. I felt I should share it. Heres how to install it.

Firstly you should install cygwin and xorg-base for cygwin.com

Download the fluxbox 1.0.0 tar bz2 file and extract the file into cygwins root.

tar -xvjf fluxbox-1.0.0.tar.bz2 -C /

Now add fluxbox to your ~/.xinitrc file. Mine contains just the one line

fluxbox

Dont forget to ensure the defaultserverargs value in the /usr/X11R6/bin/startx file doesnt have the multiwindow argument. I.e change the line

defaultserverargs="-multiwindow -clipboard"

defaultserverargs="-clipboard"

cygwin and blackbox 0.70.1

Neil Wightman — Mon, 28 Apr 2008 16:24:30 +0000

Here is a step to step guide to get blackbox working with cygwin.

Firstly you should have cygwin and xorg-x11 too. You should check the default xserver works. I.e you should be able to start a xterm. Once you have that we can concentrate on getting blackbox installed.

Download blackbox-0.70.1.tar.bz2

Extract

tar -xvjf blackbox-0.70.1.tar.gz -C /

Edit ~/.xinitrc and add blackbox to your the file. In my case this is the only line in my file.

blackbox

Edit /usr/X11R6/bin/startx

defaultserverargs="-multiwindow -clipboard"

defaultserverargs="-clipboard"

Fire it up and you should see this

Warning: I had to disable Unicode fonts in blackbox to get it working with cygwin. I have no idea why, but if blackbox tries to use unicode fonts all you get is boxes instead of the correct font renderings.
