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:
- ^U
- in Wordstar mode
- ^QU
- in Pico mode
- ^_
- in Emacs mode
- u
- in vi
command mode
- ^U
- 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:
- ^KN
- in Wordstar mode
- ^QC
- in Pico mode
- ^X^N
- in Emacs mode
- #
- in vi command
mode
- ^K
- 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:
- ^KM
- in Wordstar mode
- ^QM
- in Pico mode
- altX
- in Emacs mode
- <ESC>;
- in vi command mode
- ^E
- 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
