[Pharo-dev] Zinc-rest URL matching
Hi,
I use Zinc-Rest and it works like a charm, really simple to quickly get
something working.
I have a question about URL pattern matching that is used to dispatch request
to the right handler.
I want to have following URLs:
/foo/*
/foo/latest
I defined 2 handlers with following patterns:
#('foo' '*')
#('foo' 'latest')
I was expecting that the more precise handler was chosen but it was the generic
handler (with '*'). Is there a way to do that?
It is not blocking because I can use the same handler to manage both patterns
but I would prefer to have them separated as the semantic is not the same.
Regards,
Christophe.

My first answer would indeed also have been to handle both cases in one call (I
did similar things in my projects). But now that you mention it, I think this
can be fixed quite easily. Have a look at the following version:

Thanks for the feedback, this is really helpful.

Hmm, I thought about other ways of sorting patterns, but they will all be quite
complex. [ Also remember that from a design standpoint, #pattern is not
external, only #match: is, as there could be other approaches to matching ].
The trick with #order is very simple and only has to be used when there is a
actual conflict, which is quite seldom I think.
I can think of more conflicts than the one you can up with
/tasks
/tasks/*
/tasks/last
/tasks/*/items/*
/tasks/last/items/*
/tasks/*/items/last
What I mean is, it is not just the number of stars. [ More like the longest
match ]. But if you would come up with something general enough I would be
interested.
BTW, REST API design is quite hard, we have discussion about this subject here
every week.

[Pharo-dev] Which Character Encodings do you want/need in Pharo ?
Hi, ZnCharacterEncoder and its subclasses in the package Zinc-Character-Encoding-Core (a standard part of Pharo) have the following features: - proper Unicode Character/String to/from byte(s) encoding/decoding - calculation of encoding size per Character/String - proper handling of holes in tables with exceptions (strict/lenient) - properly backing up one character on a binary stream - simple, efficient, documented - convenience API - optimisations for some encodings Together, they support the following encodings: - utf-8 - utf-16 (big/little endian, bom detection) - null - iso-8859-1 (latin-1) - iso-8859-2 (latin-2) - mac-roman - cp1250 - cp1252 - cp1253 - koi8r - iso-8859-7 - iso-8859-15 The question is, what other encodings do you want/need ? There is already a request to add CP1251. New byte encoders are easy to add, based on the official Unicode mappings that can be found here: http://unicode.org/Public/MAPPINGS (these are automagically parsed). Please help us make Pharo more international friendly. Sven

Re: [Pharo-dev] Which Character Encodings do you want/need in Pharo ?

Ok this is strange the ISO 8857-7 is available with Chrome as an encoding , I tried it and it turns Greek to weird signs. Actually I tried also several others available for Greek by Chrome and none works apart from the default which is UTF-8 Also you can ignore my request as I tried Pharo with True Type fonts with Arial and it can display Greeks just fine.

wow 500.000 is a huge number for my needs. How about animation ? I assume its similar situation there too. Well then I have little reason not to use it. Hopefully I will make a few contributions too :) When I first used Roassal I was sceptical on its design , but now that I see more and more people using it and more documentation about it I see its going to a direction I wanted to go. I also see that Roassal works well with Morphic and Spec which is very good too for my needs. Great job ! Should ask questions here or in stackoverflow ?

Actually I tried also several others available for Greek by Chrome and none works apart from the default which is UTF-8 You misunderstand how this works, let me try to explain using Pharo ;-) When a website serves a page containing non-ascii content, like ελληνικά, it needs to convert from characters to bytes using an encoding. This is normally done by adding a parameter to the content-type of the page being served. Modern servers default to utf-8. This is how you start your own HTTP server in Pharo: (ZnServer defaultOn: 1701) onRequestRespond: [ :req | ZnResponse ok: (ZnEntity with: 'Do you speak ελληνικά ?' type: ZnMimeType textPlain) ]; start. It will respond with the same text to any request. Try browsing http://localhost:1701 In code, you can do it like this: ZnClient new get: ZnServer default localUrl. Here is how you check the content-type being used: (ZnClient new get: ZnServer default localUrl; response) contentType. You will see that it is text/plain;charset=utf-8 which is the default used by Zinc when serving textual content. Asking/forcing your browser to interpret these bytes using a different encoding is wrong, since the data was not encoded as such. But the server could also be using a Greek specific byte encoding, like this: (ZnServer defaultOn: 1701) onRequestRespond: [ :req | ZnResponse ok: (ZnEntity with: 'Do you speak ελληνικά ?' type: (ZnMimeType textPlain charSet: 'iso-8859-7')) ]; start. Now the page is served differently and browsers/clients know what to do, they will switch their encoding accordingly. Explicitly switching to utf-8 will now fail, as the content is *not* utf-8 encoded. So why is the option there in the browser ? Because sometimes, the server is lazy (and technically, wrong) by not explicitly setting the charset/encoding. That leaves the browser/client with a problem of course. For this there is a default, often utf-8, sometimes ascii, .. Zinc uses the null encoder as default (ZnNullEncoder) when the server fails to set one, you can override this default as follows: ZnDefaultCharacterEncoder value: ZnUTF8Encoder new during: [ ZnClient new get: ZnServer default localUrl ]. ZnDefaultCharacterEncoder value: (ZnCharacterEncoder newForEncoding: 'iso-8859-7') during: [ ZnClient new get: ZnServer default localUrl ]. Note however that Zinc will always follow the encoding set by the response (i.e. you cannot force another one, only use one if the encoding is missing). HTH, Sven PS: If you are on Mac OS X or Linux, you can try using curl as a client. ZnClient can return a command line that you can copy/paste into a terminal: ZnClient new get: ZnServer default localUrl; curl. $ curl http://localhost:1701/ -HAccept:*/* -HUser-Agent:Zinc HTTP Components 1.0 -HHost:localhost:1701 Do you speak ελληνικά ? By add the -D - option the incoming HTTP headers will be dumped $ curl -D - http://localhost:1701/ -HAccept:*/* -HUser-Agent:Zinc HTTP Components 1.0 -HHost:localhost:1701 HTTP/1.1 200 OK Content-Type: text/plain;charset=utf-8 Content-Length: 31 Date: Fri, 12 Sep 2014 20:15:53 GMT Server: Zinc HTTP Components 1.0 Do you speak ελληνικά ?

Re: [Pharo-dev] Which Character Encodings do you want/need in Pharo ?
I see thank you very much for the detailed explanation. I suspected it was working a bit like you described but now I know the juicy details :) Maybe you should add that text to an Encoding chapter in Pharo For The Enterprise so its widely available for people like me that are not familiar with Encodings.

Actually I tried also several others available for Greek by Chrome and none works apart from the default which is UTF-8 You misunderstand how this works, let me try to explain using Pharo ;-) When a website serves a page containing non-ascii content, like ελληνικά, it needs to convert from characters to bytes using an encoding. This is normally done by adding a parameter to the content-type of the page being served. Modern servers default to utf-8. This is how you start your own HTTP server in Pharo: (ZnServer defaultOn: 1701) onRequestRespond: [ :req | ZnResponse ok: (ZnEntity with: 'Do you speak ελληνικά ?' type: ZnMimeType textPlain) ]; start. It will respond with the same text to any request. Try browsing http://localhost:1701 In code, you can do it like this: ZnClient new get: ZnServer default localUrl. Here is how you check the content-type being used: (ZnClient new get: ZnServer default localUrl; response) contentType. You will see that it is text/plain;charset=utf-8 which is the default used by Zinc when serving textual content. Asking/forcing your browser to interpret these bytes using a different encoding is wrong, since the data was not encoded as such. But the server could also be using a Greek specific byte encoding, like this: (ZnServer defaultOn: 1701) onRequestRespond: [ :req | ZnResponse ok: (ZnEntity with: 'Do you speak ελληνικά ?' type: (ZnMimeType textPlain charSet: 'iso-8859-7')) ]; start. Now the page is served differently and browsers/clients know what to do, they will switch their encoding accordingly. Explicitly switching to utf-8 will now fail, as the content is *not* utf-8 encoded. So why is the option there in the browser ? Because sometimes, the server is lazy (and technically, wrong) by not explicitly setting the charset/encoding. That leaves the browser/client with a problem of course. For this there is a default, often utf-8, sometimes ascii, .. Zinc uses the null encoder as default (ZnNullEncoder) when the server fails to set one, you can override this default as follows: ZnDefaultCharacterEncoder value: ZnUTF8Encoder new during: [ ZnClient new get: ZnServer default localUrl ]. ZnDefaultCharacterEncoder value: (ZnCharacterEncoder newForEncoding: 'iso-8859-7') during: [ ZnClient new get: ZnServer default localUrl ]. Note however that Zinc will always follow the encoding set by the response (i.e. you cannot force another one, only use one if the encoding is missing). HTH, Sven PS: If you are on Mac OS X or Linux, you can try using curl as a client. ZnClient can return a command line that you can copy/paste into a terminal: ZnClient new get: ZnServer default localUrl; curl. $ curl http://localhost:1701/ -HAccept:*/* -HUser-Agent:Zinc HTTP Components 1.0 -HHost:localhost:1701 Do you speak ελληνικά ? By add the -D - option the incoming HTTP headers will be dumped $ curl -D - http://localhost:1701/ -HAccept:*/* -HUser-Agent:Zinc HTTP Components 1.0 -HHost:localhost:1701 HTTP/1.1 200 OK Content-Type: text/plain;charset=utf-8 Content-Length: 31 Date: Fri, 12 Sep 2014 20:15:53 GMT Server: Zinc HTTP Components 1.0 Do you speak ελληνικά ?

Re: [Pharo-dev] Starting with Roassal 2
Yes, you can use SVG path as a shape for an element. What you chose really depends on your objective. If you want to draw nodes (elements) and connect them with edges (lines), I guess, the preferred API is Roassal2.

I wanted just a simple line by itself starting from one point and ending to another in a single line of code.

Basically RTEdge is the object you want to manipulate with. I do not know what is the objective of your example. But there is way how you could write it. -=-=- | v elements models | models := (10 to: 60 by: 1). v := RTView new. elements := (RTEllipse new size: #yourself; color: Color red) + RTLabel elementsOn: models. v addAll: elements.

I am getting an error MNU Array element why ?
