# 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.
