fobos local variables

[szaghi]

Add feature: allow definition of local variables inside fobos file that can be shared between different modes/options

Hello Stefano!
This feature does not seem to be documented, so I'm unsure of exactly what it means :(

Hi Tomas,

happy to read you again.

You are right, this is not documented yet! Indeed, I have planned to refactor FoBiS and its documentation, but I have not yet found the time. However, the meaning of this feature (that is implemented!) is very simple: you can define variables and use them into different "modes" and or "options". For a practical example see this

https://github.com/szaghi/BeFoR64/blob/master/fobos

The [common-variables] is not actually a building mode rather a container that can be used for sharing options that are common into different modes. In the linked examples the options:

$CFLAGS_SHARED = -cpp -c -assume realloc_lhs -fpic
$CFLAGS_STATIC = -cpp -c -assume realloc_lhs
$LFLAGS_SHARED = -shared
$DEBUG         = -O0 -debug all -check all -warn all -traceback -std03
$OPTIMIZE      = -O2

are local variables that can be used elsewhere inside the fobos file. For example see the template-like modes of the same fobos file... oh yes the template is another new feature...

A variable can be used into the option definitions as you aspect, for example:

cflags    = $CFLAGS_SHARED $OPTIMIZE

The local (global?) variable are defined and used by the $ prefix.

Until I will have the time to refactor the code, I hope this can help you.

Thank you! I'm sure this will be useful for me :)

@Myself: remember to document this feature!

Hello Stefano,
today I realised I could use this feature! So now I'm here to remind you to document it in the wiki ;)

[szaghi]

:-) Good job!

I am doing it now...

Dear Tomas,

these are for you:

• https://github.com/szaghi/FoBiS/wiki/fobos-modes-templates
• https://github.com/szaghi/FoBiS/wiki/fobos-modes-variables

I am sorry for my bad English... I hope they are clear enough.

Let me know how you will use them... :-)

See you soon.
