[Bashburn-info] Nick, I'm reverting the change you made to configfunc.sh

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

     (( ${!BB_CONFIG_VAR} == 0 )) && return 1

This is correct. BB_CONFIG_VAR is either equal to BB_CONFIG_MODIFIED or 
BB_ADVANCED_CONFIG_MODIFIED. So what I'm doing is to test to see if the 
correct variable is set to 1 or 0.

You can't test to see if it's true unless you set it equal to the string 
'true'. Also, if you really meant the return value of the true program 
then that's something else entirely.

Well, if I go to the config menu, I get this if I exit ~ without/or with
~ changing anything:

/usr/lib/Bashburn/lib/func/configfunc.sh: line 32: ((: == 0 : syntax
error: operand expected (error token is "== 0 ")

If I set it to read

${BB_CONFIG_VAR} == true

all works and functions correctly.

Surely in bash, a $VAR that == 0 is TRUE, == 1 is FALSE (I am teaching
you to suck eggs here ;-)  ).

I need more info. I'm not getting a syntax error.

Just so you know what's happening, 

    (( ${!BB_CONFIG_VAR} == 0 )) && return 1

says, "Indirect through BB_CONFIG_VAR and see if it's value is 0. 
BB_CONFIG_VAR is only ever equal to either BB_CONFIG_MODIFIED or 
BB_ADVANCED_CONFIG_MODIFIED.  Both of those variables are declared to be 
of type integer using typeset -i

typeset -i BB_CONFIG_MODIFIED=0
typeset -i BB_ADVANCED_CONFIG_MODIFIED=0

So, if you test (( ${BB_CONFIG_VAR} == 0 )) it will always be false. 
And if you test to see if it's equal to 'true' then that's a problem also 
because you're testing it inside an arithmetic test, i.e. (( )) instead of 
[[ ]]. Because bash does not require integer variables to be preceeded by 
a dollarsign in an arithmetic context, it should complain that there is no 
variable called true but instead it just converts the true to a 1 because 
it's not equal to 0.

Something is going on where you might have (for some reason I don't know 
about) a value for BB_CONFIG_VAR of null ("").

I need to see more about why you're getting a syntax problem.

I just checked in a change. Tell me if it fixes it for you.

Don't know what to say. Can you start putting print statements in? When 
you go into bbconfmenu, BB_CONFIG_VAR *has* to be one or the other.

You can see it being set in configure and advanced.

OK, I think I have your logic here.  This works too (for me (tm) )

get_confirm()
{
    (( BB_CONFIG_VAR == 0 )) && return 1


It works perfectly... I change something, that test fails so I get asked
if I meant to apply changes - if I don't change anything, nothing
happens and I go back to menu.

This kinda sucks having to do this long distance like this.

Next step might be, after your echo, to add something like

echo "!BB_CONFIG_VAR = ${!BB_CONFIG_VAR}"

Having said that, I have an idea....

I'm wondering if you're somehow causing the ! in ${!stuff...} to be 
interpreted as a history expansion character.

Run this one liner for me:

#! /bin/bash
echo $SHELLOPTS

The value printed for me is
braceexpand:hashall:interactive-comments

If yours is printing out something that has histexpand in it then we've 
found the problem. I kind of doubt it but it's worth checking.

It works!

What gets me is why you do not see these issues, yet everybody does,
Steve?

Do you set up some sort of test environment of sorts that could hide

No. I always do it the same way.
(as root) ./Install.sh 

bashburn

and if I need to make sure I see any funny stuff,

script
bashburn
exit
vi typescript

I'm making a couple of changes to make it even better. :-(

Hold onto your hats.
