Re: [Pharo-users] ZnClient and percent characters

by PBKResearch

Sven As I read the code, there are two methods in ZnMetaResourceUtils class which specify percent encoding of queries, #queryKeyValueSafeSet and #querySafeSet. The first is used in encoding the (key, value) pairs, the second in encoding the fragment after the #. It is not clear whether we need separate safe sets for the two cases, but in any case the first one was obviously the one to change to fix Jimmie's original problem. Having been accused of monkeying with your code in an unreliable way, I shall keep my head down in future. It's a pity - I find it quite enjoyable trying to help people, and trying to prove that my elderly brain is not completely addled.

Later on, we began reading the specs better and decided to follow them more closely, that is why there are now different safe sets. Now, we can (and should) all read the different specs, and try to learn from things in the wild as well from other implementations. The quote from http://en.wikipedia.org/wiki/Query_string was incomplete, it said 'for HTML 5 when submitting a form using GET', which is a very specific context. ZnUrl was written against RFC 3986 mostly. Now, maybe we made a mistake, maybe not.

Find the class ZnResourceMetaUtils (in the package Zinc-Resource-Meta-Core). Locate the class side method #queryKeyValueSafeSet. Remove the comma from the string. With this change your âGoogleâ example generates the query line with the â%2Câ encoding of the commas. Of course, with this change a comma in the value field of a query will always be encoded.

Re: [Pharo-users] [Pharo-dev] New Tool: Catalog Browser in Pharo 5.0

by Tudor Girba

Really cool! About the spotter integration, it is really nice to be able to search and find new projects like this. Well done. But, there are two things that I would change: - Right now, the processor order is 10. If you search for GTSpotter, you will get the catalog project before the class: [image: Inline image 1] I would rather prefer the order to be next to the Metacello configurations, so I would make it 90. The reason is that the things that are in the image should take precedence because they are much more often used. - For the preview, I would put the details that we have about the project. - Also, if you are at it, it would be nice to add an inspector extension for showing all projects of a CatalogProvider and to add a load action for a CatalogProject object :) Cheers, Doru On Thu, Jun 11, 2015 at 8:55 AM, Torsten Bergmann <astares(a)gmx.de> wrote: > Hi, > > maybe you already noticed.

It is much easier to type a message (like accept) and hit enter and you get a MessageList/Browser with that result. Instead, in spotter, you have to - scroll through the list of all other search results (like classes) - dive in the list of all implementors - scroll again and no easy way to open a message list with all implementors. But: It is MUCH easier to configure or extent Spotter (if you understand the badly documented concepts behind). Spotter is not a perfect replacement for Spotlight, but spotlight wasn't perfect/accurate too. For example, search for String and you got all possible classes or methods with String in its name but NOT the class String itself, (not even if you scroll down, because the search result includes only 100 entries). There are often symbols in the resultlist that aren't messages at all and if you select that result you get "There are no imiplementors of ..." this annoyed me a lot.

You could have an extension method in ZnResourceMetaUtils that returns the character set you need to have encoded. In ZnClient you just set your ZnUrl derived class object as #url: > Cannot think of anything better for a quick resolve of your problem. > Norbert >> Am 11.06.2015 um 00:26 schrieb Jimmie Houchin <jlhouchin(a)gmail.com <mailto:jlhouchin@gmail.com>>: >> >> I am not an expert on URIs or encoding.

New Tool: Catalog Browser in Pharo 5.0

by Torsten Bergmann

Hi, maybe you already noticed. The latest update for Pharo 5 which is 50103 (see [1]). includes a new tool called "Catalog Browser". Where to go =========== You will find it under "Tools" -> "Catalog Browser" and it will display the configs together with the catalog metadata like project description. The code is managed with a configuration similar to what we have for a few other packages/projects. The tool was written by Esteban Lorenzano with small improvements like spotter integration from my side. Feel free to contribute more features. The repository can be found on SmalltalkHub [2]. This new tool basically gives you access to all available configurations aggregated at [3]. You can use a small UI to search and load the configs (see world menu -> "Tools" -> "Catalog Browser". But you can also use Spotter to load a config. Example on how to load ScriptManager config: ============================================ - open Spotter (SHIFT + ENTER on Windows, ...) - type in "Script" and you will find a spotter category "Catalog Projects" with "ScriptManager" in it - just hit enter and the config is loaded Same for all others, so try with "Seaside", "MongoTalk", ... In the short/mid-term this new tool should replace the existing config browser as it gives more informations about the projects. What to do next: ================ - give feedback - we should update all our configs with catalog descriptions - it would be nice if the spotter integration would include also a preview of the project description - ... If you want to contribute just tell Esteban so he can add you to the project.
