[Pharo-users] caching proxy for domain data

[Siemen Baader]

Hi,

I'm looking for something to hold a cached version of a parsed domain
model, typically from large HTML or CSV files on disk, parsed with
XMLHTTPParser or NeoCSV. Occasionally also JSON and HTML from a web
service. The files are frequently updated, so it should check for this at
least on disk and reload before returning the cached model to the
application.

It's not really difficult to implement and I have several "satisficing"
solutions implemented, but I think it ought to be a common problem so maybe
there is something matured and well abstracted out there. It could
even/also be a design pattern common to industry applications. Have you
seen anything?

cheers

Very interesting, I'll check it out! And yes, I agree - it is very helpful
to be able to extend and also automate a productivity system with any
concept from one's life. Very cool that you have extended it with Corey's 7
habits. I have meeting announcements that I'd like to automate across email
and SoMe channels, and recipes, meal planning, online grocery ordering and
bulk cooking. The Dynabook approach sort of legitimates the approach of
evolving such a system yourself as empowering literacy, rather than using a
patchwork of specialized end user applications. I get the impression that
Lisp folks do have an ASCII inspired Dynabook universe with Emacs and
OrgMode. We could ask Nicolas Petton.. I found his Pharo projects to be
extremely creative and well-engineered. Now he is using GTD & OrgMode and
maintaining Emacs. [3]

My own Dynabook system has a Pharo backend and internal Pharo DSL and AJAX
web app frontend based on Iliad. The latter to allow collaboration with
non-pharo end users on certain projects. I'm interested in adding
instrumental interaction [1] to the web frontend to provide context
appropriate editing tools in a feasible way, along with the context
appropriate views HTML gives me quite nicely (similar to the inspectors in
the GToolkit philosophy). A big project and certainly more to talk about...

Do you have a mobile workflow too? I use mobile a lot - for now with
OrgMode and the beOrg mobile app. I also have a wearable computer with a
Raspberry Pi, Vufine [2] and Twiddler one hand keyboard which has some
advantages over mobile because I can type faster and maintain a view of the
world through the HUD. The Twiddler is quite efficient for text/emacs-style
editing and emacs runs quite well on the Pi, so I'm still interested in
some sort of OrgMode compatibility to remain pragmatic & productive on
these journeys.

Sorry for my late response BTW, summer time... I really appreciate
TheProjectProject and the thoughts behind it.

Hi Offray,

that is very interesting material, and well described. No, it doesn't have
to be OrgMode per se, I just wanted to make use of something that already
can support a GTD workflow and implement something on top of it gradually.

I look deeper into this - thanks a lot!

[Pharo-users] searching for pharo code on disk

[Siemen Baader]

Hi,

I'm looking for some code I wrote maybe 7 years ago. A web scraper that
collected data from a specific web shop. It must be somewhere in my home
dir in an image, perhaps Pharo 4.0, or in .mcz files stored by Monticello.
What would be a good way to search for it? I tried

`grep -r --include \*.changes "server-url.com" ~`

(I also asked ChatGPT as per the previous discussion on this list, and it
tries its best to teach me about grep and sound very convincing while
providing me with arguments that grep can't evaluate :))


with no luck so far.

Any ideas?

Thanks,
Siemen

[Pharo-users] Pharo CMS

[Siemen Baader]

Hi everyone,

I was looking for a Pharo CMS. I got the Pier one-click image from
www.piercms.com, but it seems there is a hardcoded path in the image. I get
the error message:

Pharo cannot write to the changes file named
/private/var/folders/ImndBm_rpdOz3Bpyfiqvv0d4dc000Ogn/T/AppTranslocation/24424,42
BEB3 4E. BBC5 CMFBIElgi12/3/35/d/Pier app/Contents/Resources/Pier.changes

(the image is not there but in my ~/Downloads folder).

Any ideas how I can fix this?

And what does Pharo.org use for its CMS?

thanks,

[Pharo-users] Re: Too many parenthesis - a matter of syntax

[Siemen Baader]

Hi Kasper,

perhaps not what you are asking, but I find that this kind of nesting
happens to me when parsing serialized data (web page sources or JSON as in
your example). For me, the root cause of the problem is that these data
structures are not represented by real classes in my code. I often start
with what you are showing in a Playground, but then refactor it into
specific parsers for the web sites I am scraping. The parsing selectors go
into classes that mirror the parts of the data I am interested in. I find
this to be more declarative and maintainable, and more natural in the Pharo
environment with its browsers and code extractors.

I hope this is of any use :)

cheers

Re: [Pharo-users] pharo books as audiobooks

[Siemen Baader]

Hi Marek,

Thanks for the pointer. This is useful and interesting, but I wasn't clear
enough - I need the audio on my mobile phone and it needs to bookmark where
I left off, like audio book players and podcast apps do. Pocket has a very
nice workflow for this because I can bookmark a web site in Firefox, then
play back on mobile later. I've also used http://talkify.net and saved the
whole .mp3 file as an audio book to my mobile device, but talkify and
Pocket only work with HTML accessible over http via a public URL. But
thanks, and I'll probably learn something from this tool as well.

Besides - another reason why it would be cool if http://books.pharo.org had
supplementary HTML builds with unique anchors for chapters and sections
because this makes it very easy to point to specific sections in the books
when answering questions on the mailing list.

cheers,
Siemen

[Pharo-users] pharo books as audiobooks

[Siemen Baader]

Hi all,

I'm interested in listening to the pharo books as audiobooks, away from my
desk. I read them to learn higher level concepts and can get back to the
code boxes later to look up the details, so I'm not too worried about how
to exactly convert the code boxes to audio.

One way to enable this would be if the books were served publicly as static
HTML. One can then use the Pocket App to save them and listen on the go. In
theory this should be something that the CI system could just be set up to
do, right?

(There are apps to convert PDFs to audio too, but those I have been able to
find are inconvenient and / or expensive.)

Is anyone who is already familiar with the CI system interested in setting
this up? I'd love to help but don't have the time, unfortunately. But I'm
happy to provide feedback. I'v

[Pharo-users] transactional saving of images

[Siemen Baader]

Hi,

I have had a few occasions where I broke an image because I either ran out
of disk space or had an endless loop that grew my image endlessly (I think).

But why does Pharo not save the image & .changes file in hidden files named
eg  ~Pharo.image while it saves? Then it can rename them when saving was
successful. Many unix programs do this.

(I'm using pharo 6.1 so don't know if newer versions do this)

[Pharo-users] recovering non-ascii code in 6.1

Hi,

I have a broken 6.1 image and uncommited code with non-ascii characters in
it. When I drag the .changes file onto a new 6.1 image it won't import due
to the non-ascii code, but I can rename the .changes file so it matches the
new image's filename and import individual code changes (also with
non-chars) with Wold Menu -> Tools -> Code Changes.

Can I somehow file in the whole .changes file at once to end with the same
code state as in the original image?

[Pharo-users] Seaside or Iliad for business applications?

[Siemen Baader]

Hi,

I’m a very happy Iliad user but I’m wondering if it would make sense to
switch to Seaside for commercial development since it has a larger user
base. I have only used Seaside briefly to try it out and found I was more
happy with Iliad back then, but now I’d like to hear your input. Especially
from those of you who use it for business applications with paying
customers. My questions are:

- does Seaside support partial updates of the DOM, like Iliad, or do I need
to refresh the whole website for every interaction?

- Iliad has REST-like URLS that look clean and can be shared, Seaside seems
not to. Is this possible with Seaside?

- directly writing javascript. I suppose there is a WAComponent that can
emit raw JS?

- what is the status of Websocket / Comet in Seaside?

Is there anything else I should consider?

Re: [Pharo-users] Status of Caffeine

[Siemen Baader]

Hi again,

I played a bit with the online demo. Do you have implemented a basic file 
browser with
DOM (not canvas) UI? But it is not compatible at the Morphic level, right? So 
it is not a DOM element based backend that existing Morphic applications could 
use..?

Also, what happens when you have an exception in code in a DOM callback like 
xhr completed or a click event? Does it pop up a real Squeak debugger and 
allows coding in the debugger like real smalltalk?

Cheers,
Siemen

Re: [Pharo-users] Status of Caffeine

[Siemen Baader]

Very good!

What about the UI lag and the occasional spinner that blocks the UI, is
this related to the debugging protocol (I see that the IDEs are loaded in
iframes) that will go away when run from local, or is this something that
can be optimized away?

Thanks for the details so far!

Re: [Pharo-users] Status of Caffeine

[Siemen Baader]

Hi Craig,

Great, thanks! The minimal example seems to load fast enough. Do you think 
there is a potential to slim it down even further for a production system that 
uses the DOM as its UI, ie remove morphic and others and use the image in 
headless mode?

Thanks for the offer to work together on the Pharo port. It is too early for me 
to commit to that, but I definitely like the idea. Right now I'm just checking 
out. I'd like to use Pharo's (or Squak's) interactive development workflow to 
develop single page web apps and mobile apps in a reliable manner. 

Is there a way to run the IDE in a separate window from the actual application, 
so that the UI would behave as in production during development? I'm especially 
thinking of responsive web applications here. 

(If not then perhaps putting them into divs next to each other might be a 
decent workaround)

Cheers,
Siemen

Re: [Pharo-users] Status of Caffeine

[Siemen Baader]

Thanks!

My idea was to use it in a similar manner to e.g. Angular, with a full app 
being loaded into the browser which communicates with a backend API. But this 
requires the load time to be acceptable.. another direction would be to embed 
it in a phone gap app and use it to build DOM-based mobile apps. There a larger 
footprint would be ok.

[Pharo-users] Status of Caffeine

[Siemen Baader]

What is the status of Caffeine now - is it production-ready with Pharo, and how 
large is a minimal (not development) image with everything required to run a 
production system - i.e. what would be the load time of a Caffeine web app?

[Pharo-users] reading from a named pipe in Pharo

[Siemen Baader]

Hi,

I'd like to use an external tool to edit HTML code and then store and
version it in my Pharo image. I'd like to create a named pipe that the
external application will save to, and then have Pharo watch for whenever
the named pipe is written to and then execute code to handle the data from
there.

But I can't find any place to register a callback on FileReference and
similar classes that will notify Pharo when the named pipe is changed, and
when the external editor will read from it. Is there any support for this?

I know there are workarounds like polling or reading the file when it is
used, but I'd prefer to wire things together directly and avoid duplicating
the data if possible.

thanks,
Siemen

Hi,

I'm trying to run a headless Pharo 6.1 server on a Raspberry Pi following
the instructions on

The latest vm I can download is from 14 dec 2017 (see
http://files.pharo.org/vm/pharoS/raspbian/) and only works with Pharo 4.0.
Are Pharo 6 and 7 not being built for ARM anymore?

Also Pharo does not want to start in headless mode as indicated by the vm's
help text:

pi@raspberrypi:~/Pharo6.1-3 $ ./PharoS -headless Pharo.image  eval "5+5"
setlocale() failed (check values of LC_CTYPE, LANG and LC_ALL)
unknown option: -headless
Usage: ./PharoS [...] [ [...]]
   ./PharoS [...] -- [...]

ALSA s:
  -nomixer  disable mixer (volume) adjustment
  -soundcard  open the named sound card (default: default)
  -playback   play to the named sound device (default: default)
  -capturerecord from the named sound device (default:

  -fullscreen   occupy the entire screen

I don't. PharoLauncher didn't work for me, when I try to launch an image I
get an exception "MessageNotUnderstood: MacProcess>>waitForCommand:". So I
just downloaded images from get.pharo.org and then used Monticello to
identify the Nautilus packages versions and bisected in a 6.0 image until I
found the version that introduced the bug. Do you need the build numbers? I
suppose I can get the builds from

Re: [Pharo-users] cancel changes in Nautilus broken on 6.1?

[Siemen Baader]

The regression happens between Nautilus-TheIntegrator1352.mcz and
Nautilus-TheIntegrator1351.mcz. Pharo 6.0 uses
Nautilus-TheIntegrator1366.mcz

I'll look more to find the actual code that breaks.

Hm yes.. This is probably what I'll end up doing eventually. I was trying
to save a lot of typing work. XMLElement and ILHTMLBuilder both have useful
interfaces, and some of it is called from behind the scenes by their
respective frameworks.

> Is this very performance critical code?

I don't think so. But it is the HTML construction code of a web app, so it
*might* become a bottleneck. I don't treat it like this ATM.

[Pharo-users] casting to subclass

[Siemen Baader]

Hi all,

it seems like we cannot cast the class of object to its subclass if that
subclass has had new instance variables added to it:

http://forum.world.st/changing-the-class-of-an-existing-object-to-a-subclass-td4239041.html

But I (think) I need it - I'm transforming a DOM tree from XMLHTMLParser's
XMLElement s to a subclass of Iliad's ILHTMLBuilderElement s, and for
single occurences I would like to use the more specific subclasses, like
ILCheckboxElement. I can make the cast manually, I know when it is safe to
do.

What else could I do, apart from removing the element from its tree,
creating a new (subclass) instance and then putting this element in place
of the old one? Some #perform or `super` magic..?

hm..

thanks for any pointers!

[Pharo-users] [Iliad] raw HTML in Iliad

[Siemen Baader]

Hi all,

is there a way to render raw HTML from Iliad widgets, or perhaps mustache
templates? I'm interested in not using the builders always because I use an
external web editor that generates plain HTML and that has some advantages
in my workflow.

Is it possible do it with Seaside & Reef instead?

[Pharo-users] cancel changes in Nautilus broken on 6.1?

[Siemen Baader]

Hi all,

I downloaded Pharo 6.1 for OSX and whenever I revert changes in Nautilus
with CMD-L, the content is reverted and the orange dirty marker triangle
disappears. But when I switch to a different method, Nautilus shows the
'Content has been modified. What do you want to do?' dialog, as it only
should when content is actually different.

I use this all the time, I can't imagine I'm the only one, but I couldn't
find the problem mentioned anywhere. Does anyone else have it? What to do?

[Pharo-users] Soup bug(fix)

[Siemen Baader]

Hi all,

who maintains Soup, the HTML parser? Stef?

It seems to auto-close  (and ) tags when nested inside another
element. I wrote this test that fails:

testNestedButton
"this works with nested  tags instead of  and when there
is no enclosing  at all. but here  is auto-closed."

"a does not work either"

| soup |
soup := Soup
fromString:
'
text
   
'.
self assert: soup div button span string equals: 'text'




Where should I look to prevent Soup from auto-closing the tag, and where &
how should I submit my fix?

[Pharo-users] object serialization, STON & PharoJS

[Siemen Baader]

Hi all,

I’m trying to transpile the STON class to JavaScript with PharoJS to use it
in a client side web application. The goal is it to retrieve object(graphs)
from the server and deserialize them in the frontend via xhr.

But PharoJS doesn't support thisContext, I think that's a limitation of the
JavaScript VM. PharoJS raises "PjJavascriptTranspilationError - thisContext
not supported. Found in Collection >> #toBraceStack:". I tried to add the
 pragma to the method in the hope that it will not be needed
for my uses, but no luck.

Is the use of thisContext needed in STON, can I avoid it? I had hoped to
use STON because it is simple and well documented and unlike JSON handles
object graphs and classes.

What are my options?

Alternatively, what else could I use to serialize objects? I'm already
using Voyage & Mongo on the backend which deal with JSON internally, and I
think Moose also has a serialization component. Using a JS library in the
frontend is also an option if there is a Pharo implementation for its
format as well.

Thanks,
Siemen

Yes, it is good. But all the state is on the server, so it is not much help
for an in-browser web app. A thin client model rather than a fat client
that has a very responsive UI and also works well with interrupted
connectivity as is often the case with mobile. So not really my use case.

Exactly. It would be cool if we could unite a few competent people with
self-interest to help the project forward. I have this self-interest, but
not the skills (or time to acquire them) to do it alone. Have tried ;)

[Siemen Baader]

Hi all,

Is anyone else interested in PharoJS and making it mature for their own
commercial mobile and single page web app (and node.js) development?

I think it has a huge potential because it brings the browser runtime and
many libraries and online services from the JS world to us Smalltalkers
while letting us keep our agile development and good CS practices. But it
does not yet have the necessary features and documentation to work smoothly.

I didn't know there were 'ConfigurationOfX.mcz' files. What do they contain? 

What I want to see is what code has changed between two releases. In Git I 
would do it with a diff of the two releases' checksums. In other words, I want 
to see for releases described with metacello what the
Monticello browser can show us for versions of packages. Does this make sense? 
It seems like a very common use case to me, people must be doing it all the

[Pharo-users] diff'ing with metacello

[Siemen Baader]

Hi all,

is there a tool to diff two Metacello versions with different baselines? I
tried MetacelloBrowser (
http://www.squeaksource.com/@6xz1bzmNF75EduBA/vZ263dVA) but it does not
install on Pharo 5.0.

I need it to see what has changed when I install a new release of PharoJS
and to bisect in search for regressions.

thanks,

Also an option and more explicit than `self `working, but meaning something
else than at run-time. In the case where `self` is the current object (as
in the debugger) the code can be executed with DO like when it is later
run. That is what I would find useful for prototyping.

Yes, I had ideas along these lines as well. There could be a field above

accordingly..

[Pharo-users] self in Nautilus

[Siemen Baader]

Hi all,

in Nautilus, `self` is always the current class instance. This is great for
coding class side methods because we can test code fragments live in the
editor, but for instance side methods I have not seen the usefulness of it.
At times it can even be confusing and cause errors since a "print it" of it
looks quite like an instance (`a Listener` vs `Listener`).

Is there a rationale why `self` in instance view does not raise an error or
is nil? And, more importantly, could there be a way to set it to a specific
value (= can we browse a class with self bound to an specific instance).

This would resemble programming in the debugger, but provide the overview
that a class browser provides.

cheers,
Siemen

Actually this should have been: (no `;` between basicNew and initialize).

^ currentInstance
ifNil: [ currentInstance := self basicNew
initialize;
yourself ]

This is not a problem. But it illustrates that this would be nice to have
it unit tested separately and mixed in with a trait/mixin to avoid the risk
of manual errors in what in the end is an already solved problem - if one
wants singletons, of course.

Ok. So that's the difference between a Ruby mixin and a trait. That's a
shame, I think what Ruby does with mixins is really nice because it a)
results in less code to test, and b) makes hineritance chains more semantic
- you only inherit to model spcialization, not to reuse features.

Cyril, many thanks! I know how to implement it and it is true that it is
not much, but I had hoped to eliminate the code (and tests!) and use a
standard feature if possible ;)

[Pharo-users] singleton trait

Is there a trait to quickly create singletons in Pharo, along the way of
the Ruby Singleton mixin?

(and ideally also observer/observable, which I am going to need next..)

Perhaps it would make sense to add that custom search to Pharo.org. I

[Pharo-users] Google visibility?

[Siemen Baader]

Has anybody looked into SEO'ing any of the great documentation and archived
questions on the mailing list?

It strikes me that I often can't find the answer to questions I have on
Google, but they are often answered in material that I can find when I look
manually for some time or am pointed at it by an experienced member of the
community.

I also  miss Pharo - content on Stackoverflow, it is a very efficient way
to get past road blocks quickly.

Any thoughts or history to bring me up to speed with?

Re: [Pharo-users] making scroll smooth

[Siemen Baader]

Thanks - I did it and it seems (also from the docs) to affect the
framerate, not the discrete scroll-behaviour. Nautilus panels scroll by ca.
one line height, I want them to scroll continously, by one pixel only at a
time..

[Pharo-users] making scroll smooth

Hi All,

I'm used to and like the smooth scrolling of modern browsers and OS'es and
miss it in Pharo. It as discrete scroll deltas; when I scroll it moves the
window content by several pixels or not at all if the movement is below a
certain threshold. How can I enable smooth scroll / set that threshold to
1px? And how could I learn if I did not ask on the list?

Re: [Pharo-users] understanding existing code

[Siemen Baader]

Thanks for all these tips and reflections. There are a number of things for
me to try now.

@Hilaire: I'll try try Calypso. There are indeed several things one could
experiment with in making the important connections more visible in the
development tools. I have also been thinking of a more OSX/GT like browser
design that just opens new panels to the right and opens inheritance view,
code view, class side methods in that way too... it would be more compact
and uniform and easier to put relevant pieces side-by-side.

@Ben: Clever to use the profiler to see what the code does most of, I
didn't think of it.

Also thanks for your tips on the general workflow of understanding the
code, everyone. I'm glad you have provided so much input and discussion, I
was following it eagerly.

thanks,
Siemen

[Pharo-users] seaside javascript builders

[Siemen Baader]

Hi all,

I'm confused about the limitations and intended use of Seaside's javascript
builders. I can follow that we can do eg: "(html jQuery: 'div') remove" or
"html javascript alert: 'hello'" within the "renderContentOn: html" methods,
but how do I deal with logic and variables? How do I eg. install an event
listener and provide a browser-side function that extracts data from the
event and then passes it to the server via "html jQuery ajax"? 

Is this something to be done in pure JS returned from the #script method?

Thanks for any enlightenment!

Siemen

No, they should be there – I have just not included them yet because I
didn't know which strategy we should use to embed the subtitles. There will
be icons for both slides and video. And now that I have seen that there are
slide.js slides I will use them instead of PDF because this is snappier in
the browser.

This is a cool use case. I just googled
https://www.customusb.com/spin-flash-drive/, but haven't checked throughly.
This means I will make individual HTML files for the videos with 
tags and subtitles in them, and we can download all the content, open it in
a web browser via the file:// protocol and use the MOOC offline.

I will make a small wget command line snippet that people can use to
download the whole site recursively and put that on the bottom of the page.
Like on get.pharo.org.

Re: [Pharo-users] MOOC TOC cleanup

[Siemen Baader]

Hi Offray,

I'm not sure if this answers your question, but: the French and English
subtitle files in .vtt and .srt format are already online in directories
like
http://rmod-pharo-mooc.lille.inria.fr/MOOC/Videos/W1/C019SD-W1-sous-titres-EN/
and similar. They are linked from the main page under 'videos'. I am
looking for a way to include them in the video, that would allow you to
switch among them while the video is playing. As I said, this is a preview
of work in progress.

What is it that you would like to help with using Amara? Integrating the
subtitles or creating new ones in other languages? I'm not sure I totally
understand Amara :)

cheers,
Siemen

Re: [Pharo-users] MOOC TOC cleanup

[Siemen Baader]

Hi Stef,

I have cloned the repository and linked the slides directly from the TOC. I
also have styled it with Bootstrap labels and glyphicons, and added anchors
to every item to make them easily linkable, eg for discussions on the
mailing list / slack.

The HTML files for the exercises refer to the directory 'support' (
http://rmod-pharo-mooc.lille.inria.fr/MOOC/support ) for css and js files.
I think you have missed to put the directory on the server, the links are
broken. Can you upload it?

As for the videos, they require some sort of aggregation of subtitles and
video, either in a separate HTML file with  tags, or eg. on youtube.
At some point during or after the MOOC I remember the videos were in fact
on youtube, with subtitles. Now they are back in the custom made player on
fun-mooc.fr, which is a bit impractical because the subtitles are on the
right side, slightly out of view when attending to the lecture.

Are the videos still on youtube? I could not find them again.

Would you prefer a 'full', downloadable solution with the videos and
subtitles all on mooc.pharo.org? It would be relatively easy to script
something that generates the html files, but it would take more time than
linking to the youtube videos, and I think the playback experience on
youtube would actually be better / more cross-platform.

I have a put up a preview on
https://siemenbaader.github.io/PharoMooc-website/.

What do you think?

best,
Siemen

Sure, we could either do it at fun-mooc.fr or mooc.pharo.org. The latter is
cleaner and open to all. How do you generate it, and where is the source?
I'd like to have a look.

What is the role of WebPortal?

[Pharo-users] MOOC TOC cleanup

[Siemen Baader]

Hi all, especially Luc, Stéphane and Damien,

the Pharo MOOC course was fantastic and I use the archived material for
reference quite a lot. It is here:

https://www.fun-mooc.fr/courses/inria/41010/session01/b116d12e24ec484c984831440227ac15/

But - the English table of contents is in French, and the attached ZIP files
need to be downloaded before they can be browsed. It gets quite messy. Would
anyone with the required permissions be OK to:

- translate the TOC to English
- split the ZIP files into separate elements under their respective
headlines that can be viewed in the browser

or

- grant me the permissions to do this work for the community?

best,
Siemen

Re: [Pharo-users] Adopting someone else's image

[Siemen Baader]

Thanks. I found out that I had two unrelated problems. Spotter was one and
not critical, and the reason I had errors with Monticello was that I had
made the mistake to rename the .image file, so it didn't match the changes
file anymore.

[Pharo-users] Adopting someone else's image

[Siemen Baader]

Hi, 

I am having a problem using an image that was saved by a different user on a
different machine.

I'm trying to get started with PharoJS and have downloaded the Pharo 4.0
image from https://pharojs.github.io/faq.html#demoEsug2016. When I load the
image Spotter raises errors becasue it holds on to a FileSystem object that
holds a path within the previous user's local home directory. When I use
Montichello browser to export the packages I need to disk or online
repository, I get Error: RemoteString past end of file errors - I think this
is because Montichello tries to read the changes file and cannot.

What can I do? Is there a proper way to re-initialize the host dependent
state when taking over someone else's image? I know the preferred way to
share code without state is to use Montichello...

thanks

[Pharo-users] restoring a deleted method

[Siemen Baader]

Hi,

according to Pharo By Example [1], I should be able to retrieve a deleted
method in the Change Sorter by right-clicking it and browsing old versions.
However, I get the message 'Sorry, only actual methods have retrievable
versions'.

Is this a bug, and is there a workaround?

best,
Siemen

Hi again,

I have cloned the Pharo3DawnTheme on github and updated the installation
instructions to work for Pharo 4.0. It is on
https://github.com/siemenbaader/Pharo3DawnTheme.

Would it be better for the community to use Smalltalkhub, or is Github the
new thing people prefer?

Have a nice weekend all,

Sure - I'll do that. I'm new to Pharo and have to look a bit into how, but
I can make a fork on github and update the installation instructions or
publish a package for pharo4 on Smalltalkhub. Do you prefer either site?

[Pharo-users] Dawn Theme on Pharo 4.0

[Siemen Baader]

Hi all,

has anybody had luck using Sebastian's Dawn Theme [1] on Pharo 4.0? The
instructions on github are for Pharo 3.0 - what would I do to make it work
on my 4.0 image?

thanks,
Siemen
