Re: [Pharo-users] NeoCSVReader and an empty field at the very end of a file

by Sven Van Caekenberghe

But before you ask for help on the Pharo ML you should run the NeoCSV code on Pharo to validate that your assumption hold there. If not, it is a porting error/problem. And unit tests are *VERY IMPORTANT* to maintain our sanity across versions and/or platforms. Again, what you report as a potential problem isn't one, I think. Please test on Pharo itself. > On 01 Jul 2015, at 21:07, jtuchel(a)objektfabrik.de wrote: > > I gave up on porting tests.

You mean RewriteRules? I was planning to do that, for this exact reason. But you know how things go when there is a long list of priorities. I know it saves a lot of time and makes porting so much more safe, but it needs an up-front investment in time...

I gave up on porting tests. VAST doesn't support creating Arrays with curly braces, and they are used all over the place in Pharo code. I wuld use them if I had them, so this is not an accuse or anything. It's just a huge load of work to keep tests up to date when porting newer versions, so I just ignore tests when porting.

Re: [Pharo-users] HTTP file logging for Zinc

by Esteban A. Maringolo

Thank you Sven! How does it work with FileStreams when the requests come from different threads of the server? I mean, is FileStream thread safe? I guess that if I have multiple images I should have a file per image, otherwise I couldn't write to a single file. I will add the payload logging somehow. Maybe writing to an SQLite db. Thank you again. Esteban A. Maringolo 2015-07-01 12:01 GMT-03:00 Sven Van Caekenberghe <sven(a)stfx.eu>: > Esteban, > > > On 29 Jun 2015, at 21:40, Esteban A.

Is it possible to skip whole class from testing? I could do "self skip" for individual methods, but the problems arise even in setUp so I would like to stop the whole class from being tested. Is that possbile? Thanks, Peter

Seeking help to build an accordion widget for GUI of sQuick

by Jigyasa Grover

Hello All :) I am a newbie in Pharo and have started to build my first application i.e. an offline text search application namely searchQuick. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. Currently, I have built the basic structure of the application using Morphs and have a lot to cover on the GUI part. sQ basically returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. I plan to build an accordion widget (https://jqueryui.com/accordion/) or something similiar to view the results. I seek help on the implementation of this part. Looking forward to a positive response. Regards Jigyasa -- View this message in context: http://forum.world.st/Seeking-help-to-build-an-accordion-widget-for-GUI-of-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

loading with gofer without network

by Christophe Demarey

Hi, I'm trying to load a package (mcz) from the package cache with Gofer. |gofer| gofer := Gofer new repository: MCCacheRepository uniqueInstance; repository: (MCSmalltalkhubRepository owner: 'Seaside' project: 'Grease11'); version: 'Grease-Core-JohanBrichau.94'; disableRepositoryErrors; load As you see, I gave 2 repositories (the first is local, the second one is remote) to Gofer. If you try to execute this code without the network, it will failed! It shouldn't because the mcz is in the package cache. I think it is a bad behavior of Gofer. It does not have to resolve references for ALL the repositories because, at the end, you only use one. I want to change this behavior to only get the first resolved reference (no need to iterate more). If not acceptable, I could only ignore repositories not reachable (disableRepositoryErrors does not work for this use case). Is it ok to change it? Christophe

Re: [Pharo-users] NeoCSVReader and an empty field at the very end of a file

by jtuchel＠objektfabrik.de

I am not complaining. It just makes porting harder. What made the thing especially strange was that I only had that problem with uploaded files because the Browser removes the trailing CrLf (or better, doesn't add another one in the multipart form data). So reading from a file all works like a charm, but not when you process the same, uploaded file on the server side...

Yes, on Pharo, #next (and #peek or #peekFor:) all return nil when #atEnd.

Re: [Pharo-users] NeoCSVReader and an empty field at the very end of a file

by jtuchel＠objektfabrik.de

Hi Sven, I didn't test on Pharo. But I remember seeing differences in the way Pharo and VAST react to reads beyond the end of a Stream. Not sure, but this could have been in NeoCSV context two or three years ago. So it is very likely I was bitten by platform differences. Thanks for answering.

It looks like Character cannot be store in a byte array. >I do not know if the bug is on the memory file system part or other. >Any idea? Why do you use MemoryFileSystemFile directly. Usually the FileSystem is the starting point. And there it works: |fs file| fs := FileSystem memory. file := fs / 'test'. file writeStreamDo: [ :stream | stream nextPutAll: 'bar' ]. fs inspect The nice thing is that you can now browse the file system and file contents with the new GT Inspector.
