[Pharo-project] How to have a package specific setting keyword (was Re: Draft chapter on Settings Framework for PBE2 now online )

[Alain Plantec]

Hi Hernan,

I've checked with #12272 and it works even with this version.
but you must extends SettingTreeBuilder with your own pragma keyword
method (with the <settingPragmaProcessor>), not SettingTree.
A example package is attached.
open the settingBrowser with: SettingBrowser browse: #('blobsettings')

hope it helps.

Hi Alain,

Thank you for the nice answer. One thing that you may like to adapt is
the hard-coded reference in #nodeList, because is preventing in
#buildPragma: to understand #myAppSettings, after evaluating
SettingBrowser browse: #('myAppSettings' )

SettingTree>>nodeList
        | builder |
        ^ nodeList
                ifNil: [
                        builder := SettingTreeBuilder new.
                        self pragmasDo: [:p | builder buildPragma: p].
                        nodeList := builder nodeList.
                        nodeList do: [:n | n model: self].
                        self checkForUnknownParent.
                        self checkForUnknownTarget.
                        self nodeList]

or maybe there is another way to specify my own tree builder?
(using Pharo1.2beta #12272)

Hi Hernan,

First you have to declare your own keyword.
To do that, extend SettingTreeBuilder for your application by
adding a #myAppSettings method.

SettingTreeBuilder>>myAppSettings
<settingPragmaProcessor>
    "Process a<myAppSettings>  pragma"
    currentPragma methodClass theNonMetaClass perform: currentPragma selector
with: self.


Then you can use<myAppSettings>  as you do with<systemsettings>  for the
settings declarations.
In order to open the SettingBrowser, just indicate the keywords you want:
(SettingBrowser browse: #('myAppSettings'  'systemsettings'))
or
(SettingBrowser browse: #('myAppSettings' ))

I will update the settings chapter with that.
Cheers
Alain
