ido-mode in emacs has this great feature where it remembers old buffers you have had open in the past and offers then as choices when switching buffer using
C-x b. The problem is that sometimes it will have names in the list you’d rather it didn’t remember. The solution is easy, simply hit
C-k to instantly kill the entry under point.
I’ve been trying to get gnus working in emacs in win32 for the past few days. There were a number of obstacles to overcome:
- Install gnutls
- The gnus README.w32 says gnutls should be installed and in the path. I found that it must be in the windows system path to make it work. Setting the path within emacs was not good enough. So add
C:\Program Files (x86)\gnutls\bin;C:\Program Files (x86)\gnutls\libto your system path by going to
Start/Edit System Environment Variablesthen click
Environment Variablesand edit Path in System Variables
- you need to edit the emacs variable
gnutls-trustfilesto point to windows paths to .crt files. by default it had paths to unix locations. The only way I could find to get these files was to install cygwin and then make
Unfortunately these last two steps were not obvious to me and it took me quite some time to work through them.
Tip: if you need to debug gnutls, try setting
(setq gnutls-log-level 50).
Now all I need to do is learn gnus!
For some reason I never thought to search for this before. It turns out, if you CMD+double click on a web link in Terminal.app it opens the link in your browser. Very handy. CMD+Shift+double click for OSs older than Lion.
Recently I had a list of things in a org buffer that I wanted to turn into a numbered list but couldn’t find an elegant way to do it.
The solution I came up with was to use a regex-replace to insert
1. in front of each line. Then I used org-mode’s
C-c C-c to renumber the lines.
I also asked on #org-mode on irc. Two interesting solutions were suggested.
- use string-rectangle
- use org-mode’s org-toggle-item
use the string-rectangle function via the keyboard shortcuts:
C-x r t 1 . <SPC>
string-rectangle is new to me but seems as though it could be very useful. Thanks quicksilver for that suggestion.
which is described as:
Insert separator line in table or modify bullet status of line.
Also turns a plain line or a region of lines into list items.
Calls `org-table-insert-hline', `org-toggle-item', or
`org-cycle-list-bullet', depending on context.
The trick is to prefix it with C-u which supplies ARG to the function org-toggle-item which changes each line in a region into an item.
C-u C-c - then
S-right until you get to the list type you want.
Thanks Thumper_ for that suggestion.
UPDATE: zhen pointed me to rectangle-number-lines, which I did look at before but it’s default option numbers the lines without the full stop after each number. As I wanted this for org-mode, I really wanted the numbers to be formatted as “1. “. After reading the help on rectangle-number-lines though, I found that if you prefix it with the argument command
C-u it will ask you for a starting number and the format of the numbers.
∴ Select a rectangle at least one column wide of the lines you want to number then
C-u C-x r N <ENTER><backspace>.<spc><ENTER>
A while ago I discovered M-\ deletes white space between point and text.
Now I just discovered M-spc replaces tabs and spaces around point with just 1 space.
M-SPC runs the command just-one-space, which is an interactive
compiled Lisp function in `simple.el'.
It is bound to M-SPC.
(just-one-space &optional N)
Delete all spaces and tabs around point, leaving one space (or N spaces).
If N is negative, delete newlines as well.
UPDATE: You might also be interested in my list of programmatic CAD tools.
Brendan introduced me to openscad while we were at the hacker space last night. I really like it and I can’t believe I didn’t try this tool out before. You essentially write your solid design in a programming language. Its simple to learn and very easy to get up and running.
Maissa and I bought our tickets for WordCamp Sydney. Hope to see you there!
