Dimitris,

Could you please do add a link in
https://github.com/SquareBracketAssociates/PharoWiki

to Torsten's wiki

 http://wiki.astares.com/pharo

It has over 500 pages with good content I was not aware of

yes. But I think it gets more difficult in Pharo7? So being able to load old 
code to rewrite it would be nice. :)

Re: [Pharo-users] Loading and saving packages to filetree repos

[Luke Gorrie]

I wish that somebody would take my original question at face value.

It is frustrating to be told that I don't really understand the problem. I
actually believe that the solution I am looking for is what I need in this
project at this time. I don't want to write an essay-length justification
for this position though.

Re: [Pharo-users] [ANN] Pharo wiki , is here

[Dimitris Chloupis]

Oh thanks for reminding me, there is no make a github account for those not
familair with github / git

you make any submission you want here in this thread and I will port it to
wiki with copy paste and a bit of structuring :)

As I said this wiki is very unofficial so anything will be accepted as long
as of course its related to Pharo

Re: [Pharo-users] [ANN] Pharo wiki , is here

[Dimitris Chloupis]

Completely up to you , personal I love having many options.

This is my wiki thus will be maintained by me.

Basically it occurred to me that because I already spent time reading
mailing list posts , then why not copy paste this extremely valuable posts
to a wiki with some structure that is much easier to navigate for newcomers
compared to archives of mailing lists.

I have no intention of maintaining the content to keep it up to date
because I agree that Pharo books should remain as the single source of
polished official documentation.

The wiki is there to act as a clipboard for content that may or may not
enter into one of the books.

My No1 goal is a zero maintenance , zero cost , zero learning curve wiki (
assuming you are already a github user). Because also is part of our github
group for the books all contributors have already immediate access to it.
So I think for my goals this solution is by far the best.

I have no intention of creating a swiki for Pharo because as you so
correctly said , software won't be much of a problem, keeping the content
up to date will be.

Keeping up to date Content is something I deal with only Updated Pharo By
Example. It's Definetly far harder than copy pasting stuff.

I'm afraid you might do newbies a disservice by adding yet another way 
of loading and saving combinations of packages. Dependency management is 
a 5-dimensional problem, so there are no solutions that are both simple 
and cover the needed variation [1]. In the current discussions on 
version management on this list the focus seems to be on the solving of 
simple problems, whilst avoiding the question of how to deal with many 
repositories. Metacello might not be ideal there, but it provides a 
shared solution.

Re: [Pharo-users] Loading and saving packages to filetree repos

[Thierry Goubier]

Hi Luke,

ok, it's a high tech solution, this is more because I could not on the 
spot remember what you would need as a script (and also because your 'no 
metadata' requirement makes the filetree solution problematic).


But I'd suggest still one bit of advice that is implicit in my solution: 
create at least a baseline for your project (covering say all packages 
in your repository); instead of hacking around with Monticello and 
FileTree, it will allow you to use a simple Metacello command to load 
everything and prepare correct, long term use of your project.


And you will have the save everything as well.

Regards,

Thierry

I don't know what AltBrowser is, but just as a user I need to get a bit 
more "winnage" before I am ready to take another iteration at learning

Hoi,

I want to have a quick "cheat mode" for loading and saving the
Smalltalk packages in my project. This is to make life easy for
newbies who are not very familiar with Monticello and Metacello.

The "cheat" is to assume that there is one filetree://
repository that contains all of the relevant packages, and all
we need to do is load or save each of those packages in that
repository.

I have the loading part working already:

  repo := MCFileTreeRepository new directory: '/foo/bar/baz'
asFileReference.
  repo allFileNames do: [ :file |
  (repo versionFromFileNamed: file) load.
].

but now I am wondering how to do the saving part? That is, given
a path to a filetree repo like '/foo/bar/baz', how do I save
each package in that repo i.e. export the code in the image?

Ideally I would like the same operation to skip metadata that is
likely to cause conflicts when the code is checked into Git
later e.g. package timestamps and versions.

Tips would be appreciated :).

I still prefer to have one based on Smalltalk and as there never was an 
official one
maintain my own private hosted Pharo wiki since 2015

   http://wiki.astares.com/pharo

including lots of useful informations.

It us a Swiki server ("Winterlong" release) - so it is based on Squeak + 
Comanche.  
http://wiki.squeak.org/swiki/

I once offered it to the community but there were doubts as Swiki is not more 
maintained and a Pharo solutions would be preferable. 

Unfortunately there never was a Pharo based wiki implementation although we 
have all the bits
and pieces (Pillar, Teapot/Tealight, Zinc, ...) to write one.

I have several swikis running over the years and all of them run very very 
stable and 
without any problems. Even in case of trouble they are easy to repair and 
extend as the 
content is written into XML files.

Also it has an UNZIP and go concept - so it is easy to install/run and maintain 
or move
to a different server. Squeak community is running their swiki for years 
already. 
The only problem there is that it is not well maintained and lost of pages are 
outdated
- but this is a problem independent from the wiki technology used.

So creating a wiki is quick and easy - be able to maintain up to date infos 
another issue.

Thanks

 The next big step is getting a WebAssembly version of Cog running.
Until then, we're riding the performance improvements in the web browser
JavaScript engines. At the moment, Chrome seems a lot faster than the
others. Bert's just-in-time translation of compiled methods to JS (which
the web browser's JS engine then translates to native code) helped a lot.

> - I wonder how Tether compares to Denis' Seamless

 I think Tether's serialization takes more advantage of the fact
that the participants are live Smalltalk systems with many of the same
objects already in all locations. Tether also attempts to allow remote
messages with parameters from multiple object memories (e.g., in a
context on machine A, a message is sent to an object on B, with
parameters on C and D).

 Yes, Naiad is ultimately a deployment vehicle, enabling the
accurate construction and deconstruction of systems. I want a coherent
way to release apps and work in teams, livecoding all the time.
