In Windows, Epsilon's
killing commands interact with the Windows clipboard. Similarly,
Epsilon for Unix interacts with the X11 clipboard when running as an X
program. You can kill text in Epsilon and paste it into another
application, or copy text from an application and bring it into
Epsilon with the yank command.
All commands that put text on the kill ring will also try to copy the
text to the clipboard, if the variable clipboard-access is
non-zero. You can copy the current region to the clipboard without
putting it on the kill ring using the command copy-to-clipboard.
The yank command copies new text from the clipboard to the top
of the kill ring. It does this only when the clipboard's contents
have changed since the last time Epsilon accessed it, the clipboard
contains text, and clipboard-access is non-zero.
Epsilon looks at the size of the clipboard to determine if the text
on it is new, so it may not always notice new text. You can force
Epsilon to retrieve text from the clipboard by using the
insert-clipboard command, which inserts the text on the
clipboard at point in the current buffer.
If you prefer to have Epsilon ignore the clipboard except when you
explicitly tell it otherwise, set clipboard-access to zero.
You can still use the commands copy-to-clipboard and
insert-clipboard to work with the clipboard. Unlike the
transparent clipboard support provided by clipboard-access,
these commands will report any errors that occur while trying to
access the clipboard. If transparent clipboard support cannot access
the clipboard for any reason, it won't report an error, but will
simply ignore the clipboard. Epsilon also disables transparent
clipboard support when running a keyboard macro, unless
When the buffer contains syntax-highlighted text, or other text with
colors applied to it, you can have Epsilon construct an HTML version
of the text that preserves the coloring. You can then use it in a web
page, or further convert it using an external converter. Run the
copy-formatting-as-html command to copy the current region to
the clipboard in HTML format.
By default, when the Windows Console version of Epsilon puts characters
on the clipboard, it lets Windows translate the characters from the
OEM character set to Windows ANSI, so that national characters display
correctly. Epsilon for Windows uses Windows ANSI like other Windows
programs, so no translation is needed. See the description of the
clipboard-format variable to change this.
When retrieving text from the clipboard, Epsilon sometimes performs
conversions to similar but more basic characters. For instance, if you
paste Unicode U+02DC SMALL TILDE, Epsilon may replace it with the
ASCII tilde character ~. See the clipboard-convert-unicode
variable for details on Unicode conversions to and from the system
On macOS systems, Epsilon converts from Mac line termination
conventions when you paste text. The
clipboard-convert-mac-lines variable controls this.
X11 has two
different methods of transferring text between programs. The more
modern method uses the clipboard, and explicit commands for cutting
and pasting text. This is what Epsilon's commands for killing and
But an older method uses the "primary selection" to transfer text.
Traditionally, selecting text with a mouse sets the text as the
primary selection, and the middle mouse button pastes that text into
In Epsilon the middle mouse button provides panning by default, but
when you hold down Shift, it inserts the primary selection instead.
You can set the mouse-center-yanks variable to make the middle
mouse button always insert. Or you can use the
yank-x-selection command to yank X's primary selection
explicitly. Set the mouse-selection-copies variable to make
selecting text with the mouse set the primary selection. This also
puts the text into one of Epsilon's kill buffers.
If you mostly use programs that follow the older X11 convention, you
can set Epsilon to do so as well. Set the clipboard-format
1. Then Epsilon's cutting and pasting commands will
use the primary selection instead of the clipboard selection.
