[Bashburn-info] A historical idea to throw out :-)

[Steven W. O. <st...@sy...>]

There are some places in bb where we throw a prompt and ask the user for 
input, where there are a set of choices that would make sense for the user 
to type in. I'm not talking about completion. Here's an example (and 
there are many others):

+--------------+
| BashBurn 3.0 |
+--------------+
|
+--------------+ INFORMATION +--------------+
This option sets the language BashBurn's interface will be shown in.
The current setting is: English, and below is a list
of possible languages to choose from.
To cancel, just press [ENTER].
+--------------+ INFORMATION +--------------+

Czech  English  German  Italian  Norwegian  Polish  Spanish  Swedish

+--------------+-------------+--------------+

Your Choice? |>

Wouldn't it be nice for the user to be able to hit ^P or UpArrow and be 
able to cycle through the only choices that are available?

I just found out how to do it. (Highly abbreviated example code.)

ls > tmpfile
history -c
history -r tmpfile
read -r -p 'Your choice? |> '

Does anyone hate this?

Oh, I think this i a great advantage! Steven your are great! :-)

Maybe we should then backup the prior contents of the history file, so 
that after exiting bashburn the user has the history as it was before 
starting bashburn.

Interesting suggestion. The problem is that it's sort of like a cummerbund 
or a vest. You only get to choose one. ;-)

What we can do is to create a ~/.bashburn_history which would contain all 
of the history items that get gen'd *except* for the entries that would 
happen on input that expected some sort of possible enumeration.

Sound good to me. Simpler and no chance of misspellings. Go for it.
