E3 - A mini text editor


e3[ws|em|pi|vi|ne] [filename]


e3 is a complete mini application written fully in assembler, with a code size less than 10000 byte. There is a status & input line, where you can enter filenames, blocknames, find-texts and line numbers. The editor commands are similary the families of Wordstar-like or Emacs or Pico or vi or Nedit editors. For online help press ESC:h in vi mode, else Alt-H. This man page describes Wordstar key bindings only.

e3 has an UNDO mode starting in v2.2. There is no predefined UNDO level count. You can expect to UNDO at least one last insert-, delete-, overwrite- or sed_pipe-operation, but in most cases there are lots of UNDO stages available. e3 has a fixed size undo buffer and will use an external helper file if some deleted data is bigger sized than the undo buffer. This buffer is organized as a ring, overwriting older UNDO information if neccessary. So one never can say exactly how many UNDO operations are possible. For using the UNDO press one of:

in Wordstar mode
in Pico mode
in Emacs mode
in vi command mode
in Nedit mode


e3 has an arithmetic calculator built in for some simple arithmetic calculations inside your text. Place cursor at begin of the task i.e. something like: -3.002*-(2--3)= and press one of:

in Wordstar mode
in Pico mode
in Emacs mode
in vi command mode
in Nedit mode

This will insert the result into text. Use the values between -999999999999.999999 ... 999999999999.999999 with up to 6 decimal digits and the operators +-*/ and parenthesis ( ). Also available are p for constant PI and r for accessing the result of last calculation



You can switch to other editor mode by pressing one of:

in Wordstar mode
in Pico mode
in Emacs mode
in vi command mode
in Nedit mode

e3 will set a prompt SET MODE . Now enter one of e3ws, e3em, e3pi, e3vi, e3ne for setting Wordstar-like or Emacs or Pico or vi or Nedit style.


e3 accepts a filename for text editing. Switch the editor mode depending of the binary name, one of e3ws, e3em, e3pi, e3vi, e3ne
