I see no reason why. You can use ssh with username and password as well. Norbert

Hi,
using the bitbucket:// scheme and authority leads to a download url of where NorbertHartl and <password> are the credentials and 2denker is the user. The project name is stripped off. So this does not work as expected. Norbert

Thanks.
To be honest I don't watch videos if I want something to know. So I skip those nearly always. Your tutorial (didn't watch) seems to be about github and sourcetree. So it does not seem to touch any of my problems. Norbert

fair enough, its obviously your choice, but please note that text documentation is slowly dying. And no I am not talking about Pharo documentation. As you probably aware of , book sales have plummeted the last decade that adsl connection speed has been rapidly rising. So there is not even a comparison between the quantity and quality of video tutorials compared to text tutorial which we see a very steady decline. Even University who have taken their courses online have solely preferred the video format to text documentation, although you can still get some text documentation for reference purposes.

I forgot to add that I will create a new tutorial that will contain how to get the git project added to Package Browser and generally update the workflow, but I am waiting for testing also meta-data less gitfiletree and see if gitfiletree fixes its problems on macos at least ( unfortunately SubprocessOS does not currently work on Windows which is what I think gitfiletree tries to port to to fix the issues on macos).

Dimitris,
I don't really believe the text documentation is dying because I haven't seen a replacement for it. Even if it is dying I could decline that and prefer text documentation, no? :) I don't think book sales are an indicator for the health of the text domain. The medium is dying not things being text. One of the main reasons I don't like videos is because skipping is too complicated. I needed 10 times clicking my mouse to skip the first 3:30 of your video because I'm neither interested in github nor in sourcetree this time. You are telling me I should watch the video but I got the impression you didn't read any of this thread before replying ;) Your video is not about the problems I have. It is a beginner video how to use pharo and git together and that's fine. I'm glad you did it. I'm after a workflow that can be used as developer as well as in a continuous integration server without introducing to many side effects. thanks, Norbert

Myself and a lot of my friends use text documentation way more than videos. Maybe you see more video documentation because you work in visual stuff/3D. Graphical artists are more incline to use visual documentation as video. But in general, most of the people I know check a video to get a global view of something then use textual documentation when they really want to learn. And I think this is better to learn because you can go with your own rhythm. But with a video it's harder.

Unfortunately. This is the biggest drag for me after switching all my personal projects to git (GitHub for public and BitBucket for private). I had gotten spoiled by Versionner and hand-editing MetaC artifacts feels like going back to the dark ages :/

Somewhate related yes but not directly. Configurations are not that related because git and github are more than capable into creating their own versions and their own releases and thank you for touching this subject because i want to mention it in my future video tutorial on pharo git. Git has several ways of doing this , git tags or branches, while github adds releases also to that. The nice thing about git and github is that it allow you to included also external assets, like images, sounds, pdf, database files , any kind of file into your repo. But you can also keep files outside the repo and still make github releases with them, since github releases can contain external assets that do not belong to the repo together with the repo in a single ZIP file. So this is why we use Baseline and not Configurations when we work with git. You will be correct to note that my video tutorial does not touch that part and that is more begineer orientated, but then that is easy for me to explain on a future video tutorial. CI is another tool altgother, git is for version control, CI is for project automatic packaging. It allow you to pull a repo from a git or any other kind of repo and run some tests on it and then build it or do all sort of stuff on it before packaging together. Its a whole another chapter on itself and a whole new set of video tutorials and my video wont help you there, because CI is not related to git and if I made a video tutorial how to use pharo + git with CI , it would have been a CI video tutorial and NOT a pharo+git tutorial. " I do not agree on that point. Myself and a lot of my friends use text documentation way more than videos. Maybe you see more video documentation because you work in visual stuff/3D. Graphical artists are more incline to use visual documentation as video." Definitely not the reason. I don't disagree with you that most people would prefer to have text documentation to video documentation. The nice thing about text documentation is easier to seek through and find what you want. But documentation is not dictated by its users but rather its creators. Video tutorial are far , far , far easier to make. Thus why they have exploded in popularity. To give you an example, lately I am learning C++ and looking into a specific kind of IPC. IPC has nothing to do with 3d graphics its Inter Process Communication, its what I use to make pharo talk to python with sockets. Now I am investigating the fastest form of IPC, shared memory and the most popular implementation of shared memory, memory mapped files. Its just a file that is uploaded to a part of the memory that then can be shared among diffirent applications (processes) and you dont have to move data around like you do with sockets and of course its a million times faster since its just direct memory manipulation with pointers. I wont even begin to describe my surprise about lack of documentation , text documentation about such a basic subject. Examples I found were mostly C and Linux and I was searching C++ and Macos. I go youtube, BOOM! tons of tutorials most of them the past year or two compared to very dated text documentation (my best bet are blog posts for up to date info). Messing around youtube with shared memory I found OpenMP shared memory, no idea what that was, I use google to search what the hell that is, reading website description about parrelism , makes a bit sense, but I want to know more, trying to find documentation same website recommend me to go back to YouTube to watch video tutorial by one of the dudes that made OpenMP. I have read text docs about threads in the past with python , the irony is that his video tutorial even though in C and using far more complex concepts are much easier to understand follow. And this is no small library made by a random guy this freaking Intel and OpenMP is probably the most popular library for multi threading currently and parrarely programming. I can go on, C++ 11 docs , youtube wins hands down, QT docs, youtube winds hands down , pretty much any python library you can imagine , youtube wins hands down. Even I , prefer text documentation to video tutorials . I downloaded the OpenMP pdf spec as I have pdfs for many libraries , QT , python etc. But I am forced to use YouTube more and more because hands down is by far the best resource of modern documentation, there is no comparison. And as documentation creator I have to confess I prefer making video tutorials 10 times more than writting text because, well I am lazy and its just way way way easier.

To be fair my experience with pharo and git have been not always smooth either. I have the VM crashing again and again completely randomly when it was trying to pull SmaCC as dependency for my project Ephestos, had to drop SmaCC and moving my python type parsing at python side. But I find it ironic someone using Monticello, trying to equate git with dark ages, you cant get more dark ages than monticello, frankly. No offense to people who made it , its great that is in there but its full of problems and bad designs and cant even begin to be compared with Github and GIT GUI clients. Monticello is according to my personal opinion by far the worst tool of Pharo. On Tue, Jan 26, 2016 at 4:51 PM Thierry Goubier <[hidden email]> wrote:

Monticello is according to my personal opinion by far the worst tool of Pharo. No it is not. It is a version management system that understands our object and code model, a system that we control.

Obviously it will better fit Pharo since its made to work with smalltalk code, but that does not make it any less terrible. Just because you have one implementation of something that does not mean its good. Its just means its there and it works. I dont know the internal, they are not documented anyway, there are some class comments here and there but thats pretty much it. I dont even remember when was the last time monticello got an updated, I mean a serious update not just a couple of bug fixes the 2 years I have been around.
