Re: [Pharo-users] UFFI with asynchronous callbacks

[Todd Blanchard]

Just catching up

I'm trying to work with 64 bit Pharo 6.(1? 2?).

I've run into some issues that I have not been able to resolve.  I've loaded up 
TalkFFI with the LibClang library and testLocation fails.  Anything that tries 
to deal with getting a code location fails and I cannot figure out what the 
issue is yet.

Also, callbacks do not work at all.  

One might say that this is only tested on 32 bit Pharo and that's fine, but I 
have a 64 bit computer loaded with 64 bit standard libraries and recompiling 
everything to get 32 bit versions is just not practical.  Its past time to do 
the 64 bit thing.

FWIW, my test library at this point is SQLite Amalgam header to see if I can 
automatically build a SQLite interface (should be easy as it is one file) but 
it is kind of frustrating that these libclang features are not working on 64 
bit libs.  

I have been running in lldb to try to catch the crashes, and I have written a 
number of toy programs to make certain things are the sizes I expect.

Still stuck at this juncture.

Had to take a lil break and learn to program a Particle board for a work 
project but will resume next week.

Re: [Pharo-users] UFFI and Fortran

[Todd Blanchard]

I keep running into issues on 64 bit FFI.

Compiling 32 bit libraries is atypical and requires a lot of fiddling of 
unfamiliar build systems for various libraries so I'm just going to work in 64 
bit land on Mac.

Another one?  I think we've written half a dozen now, no?  There is some code 
in the VM libs that allows calling out.  I worked on one with Avi for a bit 
about ten years ago.  The callbacks/delegate bit was always problematic.  It is 
one thing to call Objective C (really easy) but another thing to integrate with 
Cocoa and accept callbacks while keeping the VM live.

I would really love one that let me write Cocoa from Pharo (especially iPhone 
apps).  

I do wonder if this new capability with Objective C blocks wouldn't maybe make 
things easier.

AFAIK, TalkFFI hasn't been updated to UFFI for Pharo 5.

Hi.

Esteban has version ported to UFFI https://github.com/estebanlm/TalkFFI.
But I don't know is it working or not.

Pretty sure that's the one I loaded.

Still having issues with libclang on 64 bit with code locations.

that was made for 32bit. 
I never tried it witht 64bit libclang so I would not expect it works just like 
that ;)

Hi Peter,

there are some other themes that are managed externally and if there will
be some issues with updating it to the latest Pharo versions, I'm sure that
people will help if they will be kindly asked. The Watery theme is working
in general but broken in many small details including the Spotter
integration. One thing that newcomers try to do as first is to play with
changing of themes and to provide them an inconsistent theme that emulates
look of an OS that is not used anymore does not throw a favorable light on
Pharo.

Cheers,
-- Pavel

Maybe. I refer the whole aesthetics of slides (even the ones with

bullet point, loosing context and perspective. My usual approach is mind
maps. In [1] you can see the exported SVG version of the one I use in a

that’s unlikely to be true. 
what you will not have, definitively, is async callbacks (that’s WIP and not 
for the immediate).

[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?

cheers,
Siemen

Re: [Pharo-users] Binary Decision Diagram Package in Smalltalk

[Steffen Märcker]

I see. How about the following (sketched) solution to avoid looping over  
all characters? It might be very well the case that you already considered  
(and dismissed) that path.


A) Assumption
In order to allow any meaningful matching, the input to the scanner is  
normalized according to the unicode spec.


B) Abstraction
Treat each character and character group of an regex as a set of intervals  
in the unicode code points. Lets call them "character tests" and lift the  
common set operations union, intersection and difference to them.


C) Construct NFA
NFA has potentially overlapping character tests at the transitions of each  
state.


D) Construct DFA
Given a product state s in the DFA and two transitions t1, t2 from the  
original NFA, add three new transitions to the DFA:
- a transition labeled with the character test of t1 minus the character  
test of t2
- a transition labeled with the intersection of the character tests of t1  
and t2
- a transition labeled with the character test of t2 minus the character  
test of t1


E) Extension
Instead of sets of unicode intervals we could also use test-functions,  
e.g. blocks. Then, in step D), the set operations are translated to  
boolean operations:

- difference t1 - t2 becomes: t1 && not t2
- intersection of t1 and t2 becomes: t1 && t2
This would allow to use optimized test functions, e.g., bdds, instead of  
relying on charcter tests only.



Cheers,
Steffen

The two main ones available, from the typical Aho/Ullman textbook, are:

- NFA to DFA conversion (i.e. build a NFA with your regular expressions,  
then convert it to a DFA)


- Direct regular expression to DFA construction

Both of them have loop of the type:

 Thanks for the offer, Steffen!  The problem is that I need to
use SmaCC for my current project, and really do not have a month
to take off and re-design the way that it builds its scanner.  
I’ve talked to Thierry Goubier about, and he doesn’t have time

either!  It would be a fun project, though, and it ought to be
fairly separate from other parts of SmaCC.  I’ve spent a fair
bit of time thinking about how to do it, but don’t think that I
will be able to actually focus on it.
 Yes, this is the essence of the issue. There are a few alternatives
about it, but none we have the time to pursue.
  An alternative approach, which Thierry has suggested, is to  
make

SmaCC work on the UTF-8 representation of the Unicode.  Then we
could represent character sets as prefix trees.  But the core
problem would still exist: you can’t run an algorithm that
repeatedly executes
  for all characters in the alphabet do:
 when there are 2^21 characters in the alphabet!
 The main issue is that `for all characters`... All the literature  
on

scanner building uses 'for all characters do'.

Hi Steffen,

in fact, I considered B) directly, but not up to the point of building onto
C) and D) (with an obvious A, but that one is a given in Pharo
implementation of strings).

Thanks for the explanation, then.

[Pharo-users] PharoLauncher directories

[stephan]

I run into all kinds of issues with the directory structure used by the 
new PharoLauncher. pharo-local seems to be shared now for multiple 
images. That makes using configurations practically impossible as they 
are not expecting to have to deal with pre-downloaded older and newer 
monticello files. The missing sources files is less of a problem.

You need to configure Iceberg with the path of the SSH key

Modulo time, as always.
If the convex hull of the dependencies need too much changes for other

Stef should have added that XPath depends on using Monty's XMLParser suite. I 
tried your snippet on XMLDOMParser, and it parses correctly. I always use 
XMLHTMLParser for parsing HTML, because I can always see the exact relationship 
between the parsed structure and the original HTML. With Soup I often found the 
match difficult or even impossible.

is there anything to do about that? i don’t want to collect them all
i have the XPath .pdf but i haven’t read it yet

Re: [Pharo-users] Soup bug(fix)

Almost certainly the HTML files will not contain the code for the actual 
pictures; they will just contain an ‘href’ node with the address to load the 
picture file from. If the web pages are built to a regular pattern, you should 
be able to parse them and locate the href nodes you want. 

 

I haven’t found any problem with the parse from XMLHTMLParser taking up too 
much memory. My machine has 4GB ram; if you have much less than that, you might 
have trouble. If you have found a systematic way to locate the picture file, 
you could minimise the size of the DOM the parser creates, by using a streaming 
parser. The streaming version of Monty’s parser is called StAXHTMLParser.

 

I have a bit of experience playing with these parsers. If you get stuck, ask 
again here with more details; I may be able to help.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

I agree with you – on the rare occasions I do still do presentations I tend to 
use CompendiumNG, which is similar to a mind map but can contain any content, 
including multimedia content.  It was an Open University project but was used 
sufficiently elsewhere that when the Open University decided they were done 
with it the project was forked and continued by others.

It’s written in Java, currently I believe there’s no binary although it’s easy 
to build.  If you just wanted the installer jar to try it out though let me 
know.

Honestly though I’d probably still use Director if it weren’t for Adobe’s 
pricing.

Maybe. I refer the whole aesthetics of slides (even the ones with

Maybe. I refer the whole aesthetics of slides (even the ones with
animations or simulations). You go in slide at the time, bullet point by

Grafoscopio workshop. Source code is in [2].

There be might be some gems in it to achieve what you want
