If I understand it well, for a local copy we need:

clone repository:

git clone [hidden email]:ccrraaiigg/ccrraaiigg.github.io.git

inside the clone to run a webserver, e.g.:

python -m SimpleHTTPServer 9090

then go to: http://localhost:9090/pharo/squeakjspharo.html

Re: Loading PharoJS Re: PharoJS

Hi Pierce

2017-06-25 13:07 GMT+02:00 Pierce Ng <[hidden email]>:

Just tried loading PharoJS with this snippet:

Gofer it
smalltalkhubUser: 'noury' project: 'PharoJS';
configuration;
loadStable

Loaded cleanly on a fresh 32-bit Pharo-50772 image. Ran almost half the tests
during which it created/deleted tabs on my open Chromium browser repeatedly.
Then the tests started a new instance of my default browser (which happens to
be Midori) and here seemingly the web socket stuff didn't work so well, so I
aborted the tests, but this I attribute to Midori not PharoJS.

On a fresh 64-bit Pharo-60501 image, while loading
PharoJSBridge-NouryBouraqadi-120, error encountered:

SyntaxError: Variable or expression expected
Object as yet unclassified makeInspect

makeInspect.
Variable or expression expected-><javascript: 'blah blah
blah blah
}'>

I think the problem is the '.' dot after the selector name.

This is not valid code for a method definition.

I think this was an error on this parser to allow the code in the first place. Now we

"fixed" the parser to indicate this as an error.

Of course it would be good to replace / fix the method definition right on this debugger window, and move on with loading th

code. But I am afraid this does not work.

So, someone (with an older Pharo version where this code gets compiled) need to load the package and fix the method

Closing the error alert box brought up a debugger at RBParser>>parserError:.

Any idea what to fix, anyone?

Cool!

A few things:
- There is a very noticable lag (e.g. ~5 seconds to open an "About" window). Any idea what it would take to deliver performance levels that feel more native?
- I wonder how Tether compares to Denis' Seamless
- I was going to ask the same question for Naiad vs Epicea, but after reading on your blog, it seems Naiad is much more ambitious than simply tracking changes
- I got a few errors off the bat

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.

Mm, I haven't delved into any of the non-fatal Pharo errors yet. :)

thanks!
