Thanks Eliot. I know this. I meant code snippet to programmatically, within Pharo, do some queries.

Such as?

 

Some times ago I worked on a MCZ importer in Moose. I will have a look at it.

The key is to ask a repository for the versions it has, get one or more versions, and create snapshots from these versions:

 

e.g. SpurBootstrapMonticelloPackagePatcher in VMMaker.oscog creates patched versions of packages.  To create a repository, e.g.

MCRepositoryGroup default repositories 

detect: [:r| r description = url]

ifNone: [MCHttpRepository

location: url

user: 'squeak'

password: 'squeak']

but there's also the package cache:

MCCacheRepository default

You can ask them what versions they have:

repository versionNamesForPackageNamed: package name

You can create these versions, and store them:

(trunk possiblyNewerVersionsOfAnyOf: latestUnbranched) do:

[:unpatched|

dest storeVersion: (trunk versionNamed: unpatched)]

And you can create "snapshots" of these versions which contain all the definitions:

version: version withPatches: patches for: package

| snapshot ancestry |

snapshot := MCPatcher

apply: (self patchForPackage: package withPatches: patches snapshot: version snapshot)

to: version snapshot.

ancestry := MCWorkingAncestry new addAncestor: version info.

^MCVersion

package: version package

info: (ancestry

infoWithName: (self spurBranchNameForInfo: version info package: package)

message: version info name,

' patched for Spur by ',

(CCodeGenerator shortMonticelloDescriptionForClass: self class),

'\\' withCRs,

version info message)

snapshot: snapshot

dependencies: {} "punt on computing dependencies; there are't any so far"

HTH

Cheers,

Alexandre

Hi Alexandre,

    .mcz's are just zip files.  The attached extracts the .st file as the package name with a .st extension instead of a .mcz extension.

Hi!

Anyone has some code snippet to extract data from .mcz file ?

Getting all the classes, doing some queries...

Cheers,

Alexandre
