Updated to Firefox 3.6 today. As usual, a very solid update, and was pleasantly surprised by the full-screen mode (finally!) that works exactly as you would want it. This was one of the few areas where Firefox on OSX was lagging behind as compared to other platforms.
There were a few plugins that claimed to enable this in prior versions, but never worked very well.
The option is available under the “View”menu and has a standard Apple-Shift-F shortcut as well.
A very simple eLisp function to add new path elements to the PATH environment variable. Very useful for adding new comint executables from within .emacs/init.el files.
(defun my-add-path (path-element) "Add the specified path element to the Emacs PATH" (interactive "DEnter directory to be added to path: ") (if (file-directory-p path-element) (setenv "PATH" (concat (expand-file-name path-element) path-separator (getenv "PATH")))))
Update (23rd Jan 2010): Separated the key-assignment and function definition.
A simple function to quickly do a diff of the current buffer contents with its underlying file. Very useful if the file has been changed outside (e.g., a log file).
;; Diff the current buffer with the file contents (defun my-diff-current-buffer-with-disk () "Compare the current buffer with it's disk file." (interactive) (diff-buffer-with-file (current-buffer))) (global-set-key (kbd "C-c w") 'my-diff-current-buffer-with-disk)
A quick and dirty eLisp function for searching on the internet from within Emacs. The default is to search using Google, but you can add to the *internet-search-urls* variable to setup additional search URLs.
By default, the search term is appended at end of the URL – however, you can also encode the specific search term insertion point in the URL by marking the position using the “%s” marker.
;;; The custom search URLs (defvar *internet-search-urls* (quote ("http://www.google.com/search?ie=utf-8&oe=utf-8&q=%s" "http://en.wikipedia.org/wiki/Special:Search?search="))) ;;; Search a query on the Internet using the selected URL. (defun search-in-internet (arg) "Searches the internet using the ARGth custom URL for the marked text. If a region is not selected, prompts for the string to search on. The prefix number ARG indicates the Search URL to use. By default the search URL at position 1 will be used." (interactive "p") ;; Some sanity check. (if (> arg (length *internet-search-urls*)) (error "There is no search URL defined at position %s" arg)) (let ((query ; Set the search query first. (if (region-active-p) (buffer-substring (region-beginning) (region-end)) (read-from-minibuffer "Search for: "))) ;; Now get the Base URL to use for the search (baseurl (nth (1- arg) *internet-search-urls*))) ;; Add the query parameter (let ((url (if (string-match "%s" baseurl) ;; If the base URL has a %s embedded, then replace it (replace-match query t t baseurl) ;; Else just append the query string at end of the URL (concat baseurl query)))) (message "Searching for %s at %s" query url) ;; Now browse the URL (browse-url url))))
The gnuplot graphing utility has always had excellent support for multiple terminal types. While the X11 terminal is a satisfactory GUI view for the graphs, I prefer to use the AquaTerm terminal on OSX as it is more ‘Mac-like’ and feels more natural.
Also, I do prefer to compile gnuplot by myself on OSX rather than downloading the pre-packaged binaries – as this gives me more control over the compilation (including getting around the stupid Apple readline bug – where Apple has essentially shipped a broken readline by using libedit to emulate the non-existent libreadline).
This local compile requires that AquaTerm be installed so that the library dependencies for aquaterm exists in:
and the corresponding headers are available at:
In addition, the AquaTerm.app itself resides in /Applications.
However, on OS X Snow Leopard, there is a catch – the version of AquaTerm is 32 bit, whereas the default compilation of gnuport results in a 64-bit version – which is not able to load the 32-bit libaquaterm dynamic libraries.
In such a case, the gnuplot compilation does succeed – however, the default terminal becomes the X11 version – which is back to square-one.
A darwinports port does exist for gnuplot – however, as mentioned in an earlier post, this port seems to depend on half of the port repository (i.e., a ton of stuff you do NOT want gets installed as well).
However, there is a easier way to get around this situation. Here’s how.
- First install the default binary for AquaTerm from SourceForge and install normally. This step is to basically setup the right folders and symlinks so that you do not have to muck with these later
- Now install AquaTerm again from Darwinports – this port has the correct patches needed – and more importantly – builds a 64 bit version by default. This will also install the application under /Applications/MacPorts/
- Now comes the fun part. We will replace two folders from the darwinports version to the previously installed AquaTerm.
- Step 1: Replace /Library/Frameworks/AquaTerm.framework with /opt/local/Library/Frameworks/AquaTerm.framework. This will ensure that the correct 64 bit AquaTerm libraries get referenced by the gnuplot compilation
- Step 2: Replace /Applications/AquaTerm.app with /Applications/MacPorts/AquaTerm.app. This will ensure that the correct 64-bit AquaTerm binary is in the correct location
- Step 3 (Optional): You can now uninstall the darwinports version by running sudo port uninstall aquaterm from a terminal window
- Download the source code for gnuplot and extract the same.
- Run ./configure (using a command line parameter to ignore the broken Apple readline) and then make and make install (install will happen in /usr/local)
That’s it! The compilation should now succeed and gnuplot will be linked with the correct 64-bit aquaterm dynamic library. Enjoy!
