[ANN] GitFileTree with no git command line at all

Hi all,

I'm announcing a GitFileTree for Pharo3.0 version with full support for
working from github (and probably all other git remote repositories such
as bitbucket) without touching any git command line, for Linux and Mac
at least (and Windows as soon as someone on windows will write the two
or three lines necessary to use the OSWindows extension).

In short, give gitfiletree: a full url to a github project and a few
other parameters, and it will do :
- clone the repo from github
- set it up as you asked for (branch and all)
- create the right local MC repository
and load whatever you want from a configuration or a Gofer script.

Example :
        MCFileTreeGitRepository fromZnUrl: (ZnUrl fromString:
'gitfiletree://github.com/ThierryGoubier/filetree.git?protocol=git&dir=repository&branch=pharo3.0'
).
        Creates a MC repository on a git clone of
github.com/ThierryGoubier/filetree.git,
        on branch pharo3.0
        stored in a directory named filetree under the Pharo working directory,
        and pointing to the repository/ subdirectory where the filetree
packages  are kept.

It is possible to add a readOnly parameter to the url: in this case, the
git clone is done with a depth of 1 and the repository disable pull and
push.

For configurations of a project on github, it becomes possible to ensure
a load of ConfigurationOfGitFileTree and then use a gitfiletree url to
clone, setup the local repository and load the package, as is done in
the latest ConfigurationOfAltBrowser.

For newcomers to git and Pharo interested in github, the process is simply:
- create a project in github
        - don't forget to register your ssh key (see the doc at github)
- install the configuratonOfGitFileTree in Pharo, either with the
ConfigurationBrowser or with:
Gofer new
        url: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main';
        configurationOf: 'GitFileTree';
        loadStable.
- Add a Git remote repository
        location: the ssh clone URL from github

- you can then start to create packages and save them into that
repository. To propagate changes to github, open the repository and
select Push. To update your local copy from github, open the repository
and select Pull. If you are a git regular user, you can keep your usual
workflow with git and gitfiletree will keep up with you.
       
Enjoy!

I suppose we should integrate this to early Pharo4 (we then can check how to improve, if needed) :))

That would be great! And testing, jumping on it, crashing it is a good
workout to design the next iteration based on our experience with it.
And don't worry, there is a lot of space for improvements :)

I'm especially happy now to be able to work directly on github with a
single configurationOfMyProject load ;)

how would you write a configuration for a project on smalltalkhub that
depends on a project on github?

If I have to load a few packages from the project on github:

add the code to ensure ConfigurationOfGitFileTree is loaded, and then
add a dependency with a gitfiletree url (on the github project) as usual.

To ensure ConfigurationOfGitFileTree, I have modified the project method
in the configuration (right after the bootstrap Metacello...)

project
        ^ project
                ifNil: [
                        | constructor |
                                "Bootstrap Metacello if it is not already loaded"
                        (self class baseConfigurationClassIfAbsent: [  ]) ensureMetacello.
                                "Load gitfiletree support if not already loaded."
                        Smalltalk
                                at: #MCFileTreeGitRepository
                                ifAbsent: [
                                        Gofer new
                                                url: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main';
                                                configurationOf: 'GitFileTree';
                                                loadDevelopment ].
                                "Construct Metacello project"
                        project := MetacelloMCProject new projectAttributes: self
customProjectAttributes.
                        constructor := (Smalltalk at: #MetacelloVersionConstructor) on: self
project: project.
                        project loadType: #linear. "change to #atomic if desired"
                        project ]

There is no MCFileTreeGitRepository(class)>>fromZnUrl: method
when loading cleanly from a config browser in Pharo 3.0 latest.
So your example in the announcement will not work.


I guess this is due to ConfigurationOfGitFileTree-ThierryGoubier.8
in MetaRepoForPharo30 but there is a more recent
"ConfigurationOfGitFileTree-ThierryGoubier.9" which loads the
new package "MonticelloFileTree-Git-ThierryGoubier.51".

Can you please copy the new config to MetaRepoForPharo30...

Thx
T.

It rely on OSProcess for Mac and Linux to call the appropriate git commands.

It uses OS Process.

Hmm, I think it needs a bit more detailed explanation.
- it doesn’t find installed git. It assumes you installed git by loading apple command line developer tools
(instead of brew, or fink)
- after installing them,trying to install SmaCC
'Git error: ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
'
Pharo 30745 on Mac 10.9

Hum, good question: it doesn't assumes anything apart from a git command
available in the default path when opening a shell.

I would have expected the open source tools to be up to date on that...

The last version of Mac I used was 10.3

You need to register to github.com and record your ssh key. I will look
if a read only access exists; there is some code inside Metacello
(github: urls) but I have no idea about how to use it (and I asked).

Thanks for trying all this :)

what should this default path be?
It could be anything on $PATH …
