# 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.
