Iceberg for files other than code?

Hi everyone,

Is it possible to read and modify files not containing Pharo code in a
repository managed by Iceberg? I am thinking of reading the repository's
README file, for example, or storing data files read by my code
alongside the code itself.

I'm not sure if you are referring to GitHub's README, but if you are, I maintain my project's README on GitHub's web site (which requires care if you're using branches). I like the markdown preview there which requires no fancy software installed on my PC. You need to pull the change to Iceberg.

There's indeed a copy of the README.md in my image's pharo-local/iceberg/GITHUBUSERNAME/GITHUBPROJECT directory, and I can even modify it using Pharo 7's File Browser. However, any modifications to it are not seen or committed by Iceberg (at least I don't know of a way to make that happen). I believe Iceberg's change detection is limited to the smalltalk files in the packages that are in the repositories it knows about. But I'm still far from an expert with this. Hopefully a more qualified person can confirm.

There's theoretically a way to run a git client outside of Pharo that knows about the local git repo that Iceberg's using, so maybe you can commit the non-Pharo files that way. However, doing that is sure to cause a "detached" state with the repo in the image. That is not a catastrophic problem, but it's more accidental complexity to deal with. I picked my battles and maintain README on GitHub.

Re: Iceberg for files other than code?

My understanding is that at the moment commits are restricted to what’s I the designated src directory, so you need to use an external way to commit non code files into your branch. These can be

1. Git cmd line

2. Another tool like IntelliJ

3. The github web bowser

If you do, you need to pull or merge in Pharo to keep things in sync.

I also hope one day we might widen the scope to commit more things directly in Pharo - particularly the readme ir other config files (I gave the same problem with exercism )

Hi Christopher and Tim,

Thanks for your comments!

I agree that managing the README from Pharo is not the most important
use case, I just mentioned it because everyone know what a README is.

A better example of what I want to do is Pharo's Help system. It stores
the individual pages as methods that return a literal string. That's one
way to store data in a package but it looks like a kludge. More
importantly, it is very difficult to use or edit the pages outside of
Pharo.

A better way to do something like that is to store pages as plain text
in the same repository as the classes that use them. But that requires
that the class can access the files as "file xx/yy/zz.txt in the same
repository from which my code was loaded". And if the class modifies the
text file, that change must be committed somehow.

I suspect that the read access part is doable somehow. The repository
checkout in pharo-local contains all the files, so it's just a matter of
figuring out the path. It's committing changes that requires some
support from Iceberg, which you says is not available if I understand
correctly.

Re: Iceberg for files other than code?

Hi Konrad - I think you can do what you describe - I think the ICeRepository entry for your project will have the path you want.

And yes, its the committing back non source files where iceberg doesn’t try to do anything (and so needs help from elsewhere).

Indeed. Here's how to get the repository for class MyClass:

repo := IceRepository registeredRepositoryIncludingPackage: MyClass
package.

And then the path ist just

repo location.

From what I saw so far it looks possible to change a file and do a
commit from Pharo code, bypassing the Iceberg UI. For some uses that
may be OK.
