MED - Mobiusloopfour's Editor

Med is a simple, easy to use line based text editor. Although inspired by ED(1), it is not designed to be compatible with it, and does not share the same commands.

Getting statrted

First, you might want to set up the build system. Run ./autogen.sh && ./configure && make. When building using make, the executable is built in /src/. To install it on your system, ensure there are no other programs called mle, and type make install. To uninstall, simply open (or clone and ./autogen.sh && ./configure) this repository, and type make uninstall.

Editing

To start editing a file, type

• mle <FILE> where FILE is a filename. IF it does not exist, it will be created when saving.

This will open med. The default user interface is rather empty... There are several commands available. They are as follows:

• .list (list) --- prints the document loaded in memory to the standard out.
• .add (append/add) --- adds text to the end of the file. Type "." (without the quotes) to end append mode. To have a line with a single dot, type "." (without the quotes). To have an empty line, type "\n" (without the quotes).
• .quit (quit) --- exits, reminding to save if applicable
• .write (write) --- write whats in the buffer to the path specified in the command line
• <NUMBER>.chg (change) --- replace a single line with <TEXT>.
• <NUMBER>.insert (insert) --- inserts text at NUMBER.
• <NUMBER>.x (quick delete) --- Delete a single line.
• <RANGE>.print (print) --- Print a range of lines (1 based indexing).
• <RANGE>.del (delete) --- Delete a range of lines

All of these have short variants, that being their first letter (without a dot). E.g: $,$d is equivalent to $,$.del

If you're confused about ranges, they are specified with <START-NUM>,<END-NUM>. Both <START-NUM> and <END-NUM> can be "$", in which case they will be substituted by the first and last lines respectively.

Note that the mle will only start executing what's in the buffer once you hit enter.

Known issues

As this is still a pre-release, there are still some bugs. Most notable are:

• The code might (?) soft-lock in some instances. Better state management will be added soon.

These issues will be fixed soon.
