[GRASS-dev] Shell scripts

[Michael Barton]

Martin,

I certainly understand that the way the command line interface is  
currently constructed. The user enters commands into the text box at  
the bottom and the output is sent to the styled text control at the top.

The discussion has been about how to improve the command-line  
experience of users who prefer this. I suggested two ways:

1) dispense with the GUI and its code altogether for such users, and  
just use the system terminal. In that case, render maps to graphics  
files that are displayed in a simple viewer.
2) enhance the current command interface in the GUI to make it work  
more like a terminal.

My diff shows how to implement option 2. When entering commands in the  
system terminal, the same window is used for input and output. There  
is a scrolling history of commands entered and any text returned as a  
result of those commands. The diff makes the styled text window-- 
currently used for output only--into such a terminal-like window.  
Commands can be entered and output received in the same window. The  
user can place the cursor on any command, hit enter, and run that  
command regardless of where it is in the window. Commands and output  
are ordered by when they are executed. Users can copy and paste from  
any part of the window to any other part. This is sort of like the  
terminal in R except that it also can run shell commands or any non- 
interactive command that can be entered from a terminal.
