Description

Add helper methods to download resources in Baseline or Metacello Configurations in Pharo Smalltalk. The files that you specify will be downloaded and uncompressed without need to write any code.

Installation

Note: You do not need to install it in your Pharo image unless you want to make modifications to this package. See the Usage section below.

EpMonitor disableDuring: [ 
    Metacello new
        baseline: 'MetacelloFileDownload';
        repository: 'github://hernanmd/MetacelloFileDownload';
        load ]

Usage

You can upload your files anywhere you want.
All your files must be already uploaded in .zip or .tar.gz
.zip or .tar.gz files will be downloaded and uncompressed in the FileSystem workingDirectory (check if you have write permissions first).
You can add several (mirror) URL’s for the same resource file (see examples below).

Add the following line in the #baseline method of your Configuration/BaselineOf class:

    "... configuration code ... "
    spec preLoadDoIt: #preLoad.
    "... configuration code ... "

To enable bootstrapping add the following two methods to your Configuration/Baseline (instance side)

ensureMetacelloFileDownload
    EpMonitor disableDuring: [
        Metacello new
            baseline: 'MetacelloFileDownload';
            onWarningLog;
            repository: 'github://hernanmd/MetacelloFileDownload';
            load ]

Add the #preLoad method (instance side) in your BaselineOf/ConfigurationOf class:

preLoad
    self ensureMetacelloFileDownload.
    super preLoad.

Resources

Finally, in your ConfigurationOf/BaselineOf class (instance side), add a method with selector #platformFilesUrl answering a Collection of download URL’s.

If you have one resource file for all OS

Assuming you have uploaded your resource files named “file1.zip” and file1.tar.gz to a “res” directory in your repository:

platformFilesUrl
    ^ Array with: 'https://github.com/yourGHUser/yourProject/raw/master/res/file1.zip' ]

If you have one URL for your resource file for multiple OS

Assuming you have uploaded your resource files named “file1.zip” and file1.tar.gz to a “res” directory:
(don’t forget the last / before the last URL fragment)

platformFilesUrl
    ^ Array with: (String streamContents: [ : stream |        
        stream             
            nextPutAll: 'https://github.com/yourGHUser/yourProject/raw/master/res/';
            nextPutAll: (
                Smalltalk os isWin32                     
                    ifTrue: [ 'file1.zip' ]
                    ifFalse: [ 'file1.tar.gz' ]) ])

If you have mirror URLs for your resource file

The same as above, specify the raw URL to your resource files

platformFilesUrl
    ^ Smalltalk os isWin32         
            ifTrue: [ #(
                'https://github.com/..../file1.zip'
                'http://www.dropbox.com/file1.zip' ) ]
            ifFalse: [ #(
                'https://github.com/..../file1.tar.gz'
                'http://www.dropbox.com/file1.tar.gz') ].

That’s all. Try your Configuration or Baseline script!
