" THE INTERACTIVE FUNCTIONS PROVIDED BY THE LIBRARY `ogonek'.
|
|
|
|
If you read this text then you are either looking at the library's
|
|
source text or you have called the `ogonek-how' command. In the
|
|
latter case you may remove this text using `M-x kill-buffer'.
|
|
|
|
The library provides functions for changing the encoding of Polish
|
|
diacritic characters, the ones with an `ogonek' below or above them.
|
|
The functions come in the following groups.
|
|
|
|
1. `ogonek-recode-region' and `ogonek-recode-buffer' to change
|
|
between one-character encodings, such as `iso-8859-2', `mazovia',
|
|
plain `ascii' or `TeX'. As the names suggest you may recode
|
|
either the entire current buffer or just a marked region
|
|
in it. You may use the functions interactively as commands.
|
|
Once you call a command you will be asked about the code
|
|
currently used in your text and the target encoding, the one
|
|
you want to get. The following example shows a non-interactive
|
|
use of the functions in a program. This also illustrates what
|
|
type of parameters the functions expect to be called with:
|
|
|
|
(ogonek-recode-region
|
|
(region-beginning) (region-end) from-code-name to-code-name)
|
|
(ogonek-recode-buffer from-code-name to-code-name)
|
|
|
|
2. `ogonek-prefixify-region' and `ogonek-prefixify-buffer' for
|
|
introducing prefix notation:
|
|
|
|
(ogonek-prefixify-region
|
|
(region-beginning) (region-end) from-code-name prefix-char)
|
|
(ogonek-prefixify-buffer from-code-name prefix-char)
|
|
|
|
3. `ogonek-deprefixify-region' and `ogonek-deprefixify-buffer' for
|
|
removing prefix notation:
|
|
|
|
(ogonek-deprefixify-region
|
|
(region-beginning) (region-end) prefix-char to-code-name)
|
|
(ogonek-prefixify-buffer prefix-char to-code-name)
|
|
|
|
The TAB character used in interactive mode makes `emacs'
|
|
display the list of encodings recognized by the library. The list
|
|
is stored in the constant `ogonek-name-encoding-alist'.
|
|
|
|
The `ogonek' functions refer to five variables in which the suggested
|
|
answers to dialogue questions are stored. The variables and their
|
|
default values are:
|
|
|
|
ogonek-from-encoding iso8859-2
|
|
ogonek-to-encoding ascii
|
|
ogonek-prefix-char /
|
|
ogonek-prefix-from-encoding iso8859-2
|
|
ogonek-prefix-to-encoding iso8859-2
|
|
|
|
The above default values can be changed by placing appropriate settings
|
|
in the '~/.emacs' file:
|
|
|
|
(setq ogonek-prefix-char ?/)
|
|
(setq ogonek-prefix-to-encoding \"iso8859-2\")
|
|
|
|
Instead of loading the whole library `ogonek' it may be better to
|
|
autoload the needed functions, for example by placing in `~/.emacs':
|
|
|
|
(autoload 'ogonek-how \"ogonek\")
|
|
(autoload 'ogonek-recode-region \"ogonek\")
|
|
(autoload 'ogonek-prefixify-region \"ogonek\")
|
|
(autoload 'ogonek-deprefixify-region \"ogonek\")
|
|
|
|
The most frequent function calls can be abbreviated and assigned to
|
|
keyboard keys. Here are a few practical examples:
|
|
|
|
(defun deprefixify-iso8859-2-region (start end)
|
|
(interactive \"*r\")
|
|
(ogonek-deprefixify-region start end ?/ \"iso8859-2\"))
|
|
(global-set-key \"\\C-cd\" 'deprefixify-iso8859-2-region) ; ctrl-c d
|
|
|
|
(defun mazovia-to-iso8859-2 (start end)
|
|
(interactive \"*r\")
|
|
(ogonek-recode-region start end \"mazovia\" \"iso8859-2\"))
|
|
(global-set-key \"\\C-cr\" 'mazovia-to-iso8859-2) ; ctrl-c r
|
|
|
|
(defun prefixify-iso8859-2-region (start end)
|
|
(interactive \"*r\")
|
|
(ogonek-prefixify-region start end \"iso8859-2\" ?/))
|
|
(global-set-key \"\\C-cp\" 'prefixify-iso8859-2-region) ; ctrl-c p
