# skex2

## interactive line editor

skex2 is a simple but functional line editor for MultICE.

### invocation

To start skex2, simply run skex(filename) from the Lua prompt.

### usage

Generally, commands and arguments are entered in the form of `command argument1 argument2 argument3` with the exception of inline execution, which is in the form of `!lua code here`.

If skex does not understand what you mean, it will output a line with a question mark.

### commands

#### q - quit skex2

Exits the program.

#### l \[start\] \[end\] - list contents

Output the lines from start to end, inclusive.

#### f \[filename\] - set the filename

This sets the filename to be used for I/O, or prints the current one.

#### r \[filename\] - load file

Reads from *filename* or the current set via **f**

#### w \[filename\] - write to file

Writes to *filename* or the current set via **f**

#### p \[line\] - print or set current line

As skex2 is a line editor, your pointer is a line, and this either prints the current one or sets a new one.

#### a \[line\] - append to buffer

Appends lines after the current line or *line* until a line with only . is entered.

#### i \[line\] - insert into buffer

Inserts lines before the current line or *line* until a line with only . is entered.

#### s \[line\] - replace line

Removes the current line or *line* and enters insert mode

#### e - executes the contents of the buffer

Basically converts it into one big string and loads it.
