jEdit Emacs Emulation Package

jEdit Emacs Emulation Package

Links

This package contains a set of key bindings and some BeanShell macros for the jEdit editor. The key bindings and macros, together, attempt to provide a better emulation of the popular GNU Emacs editor than is available out of the box with jEdit. Some of the key bindings in the shortcuts file merely bind to existing jEdit macros; however, others bind to macros provided by this package. Among the emulated functions and key bindings are the following:

Key binding	Bound to	Command Type	Description
Ctrl-n	Emacs_Next_Line	Macro bundled with jEdit	Move to the next line in the file. Similar to the GNU Emacs next-line function.
Ctrl-p	Emacs_Previous_Line	Macro bundled with jEdit	Move to the previous line in the file. Similar to the GNU Emacs previous-line function.
Ctrl-k	Emacs_Kill_Line	Macro supplied by this package	Kill from the cursor to the end of the current line in the file. Emulates the GNU Emacs kill-line function.
Alt-e	Emacs_Forward_Sentence	Macro supplied by this package	Move just past the end of the current sentence in the file. Emulates the GNU Emacs forward-sentence function.
Alt-b	Emacs_Backward_Sentence	Macro supplied by this package	Move to the beginning of the current sentence in the file. Emulates the GNU Emacs backward-sentence function.
Alt-k	Emacs_Kill_Sentence	Macro supplied by this package	Kill from the cursor to the end of the current sentence in the file. Emulates the GNU Emacs kill-sentence function.
Ctrl-w	Emacs_Kill_Region	Macro supplied by this package	Kill all text between the caret and the mark, copying it to the kill ring. Emulates the GNU Emacs kill-region function. However, this version is slightly different than its GNU Emacs counterpart: If there's any selected text (i.e., a region selected by the mouse), it kills and saves that region. Otherwise, it selects the text between the caret and mark, and kills and saves that.
Alt-w	Emacs_Kill_Ring_Save	Macro supplied by this package	Copy all text between the caret and the mark to the kill ring. Emulates the GNU Emacs kill-ring-save function. However, this version is slightly different than its GNU Emacs counterpart: If there's any selected text (i.e., a region selected by the mouse), it saves that region. Otherwise, it selects the text between the caret and mark, and saves that.
Ctrl-t	Emacs_Transpose_Chars	Macro supplied by this package	Transpose the character at the caret with the previous character, and move the caret forward one character. Emulates the GNU Emacs transpose-chars function, but without Emacs "prefix" support.
Ctrl-x Ctrl-t	Emacs_Transpose_Lines	Macro supplied by this package	Transpose the line at the caret with the previous line, and move the caret forward one line. Emulates the GNU Emacs transpose-lines function, but without Emacs "prefix" support.
Alt-c	Emacs_Capitalize_Word	Macro supplied by this package	Capitalize the character under the cursor, and make the remaining characters in the word lower case. Emulates the GNU Emacs capitalize-word function.
Alt-l	Emacs_Downcase_Word	Macro supplied by this package	Convert all characters from the cursor to the end of the current word to lower case. Emulates the GNU Emacs downcase-word function.
Alt-u	Emacs_Upcase_Word	Macro supplied by this package	Convert all characters from the cursor to the end of the current word to upper case. Emulates the GNU Emacs upper-word function.
Ctrl-Space	Emacs_Set_Mark	Macro supplied by this package	Set the Emacs mark at the current cursor position. Emulates the GNU Emacs set-mark-command function.
Ctrl-x Ctrl-x	Emacs_Exchange_Point_and_Mark	Macro supplied by this package	Exchange the caret (the current cursor position, which Emacs calls "point") with the last mark set by "Ctrl-Space". Emulates the GNU Emacs exchange-point-and-mark function.
Ctrl-o	Emacs_Open_Line	Macro supplied by this package	Insert a newline after the caret, without moving the caret. Emulates the GNU Emacs open-line function.
Alt-Space	Emacs_Fixup_Whitespace	Macro supplied by this package	Fix up white space between objects around the caret. Leave one space or none, according to context. Similar to the GNU Emacs fixup-whitespace function.

Those are just some of the key bindings. Consult the shortcuts.properties file in the downloaded package for the complete list of bindings.

Warning: Some of these macros rely on jEdit features that aren't present in versions of jEdit prior to 4.3.
