Re: Troubleshooting ByteArray

by Todd Blanchard

Try this: (PDFDocument new compression: false)add: (PDFPage new add: (PDFTextElement new text: 'Hello'; from: 10mm@10mm)); exportTo: 'test.pdf' asFileReference writeStream. Compression causes your string to be gzipâd which is a ByteArray and not a String of any kind. Unfortunately, the write stream is a ZnCharacterWriteStream which is expecting some kind of String. This is going to take some untangling so just turn off compression (which is on by default) and it seems to work. > On Jan 17, 2024, at 4:43â¯PM, Richard O'Keefe <raoknz(a)gmail.com> wrote: > > So the method is expecting some kind of string, but it received a > ByteArray, which is NOT any kind of string. > What's in the ByteArray?

Re: Troubleshooting ByteArray

So the method is expecting some kind of string, but it received a ByteArray, which is NOT any kind of string. What's in the ByteArray? Where did it come from? Why isn't it a string?

Troubleshooting ByteArray

by sergio ruiz

Hi, all. I am working on creating a PDF with Artefact (https://github.com/pharo-contributions/Artefact) and am having an issue running the first example. the Example looks like: PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello'; from: 10mm@10mm)); exportTo: 'test.pdf' asFileReference writeStream. When running this, I get the error: Instance of ByteArray did not understand #isByteString indeed, ByteArray does not have a method called isByteString. I have tried creating a method that returns either true or false (I tried them both), but I have not successfully built the PDF. The method calling isByteString looks like: ZnUTF8Encoder next: count putAll: string startingAt: offset toStream: stream "Write count characters from string starting at offset to stream." "Overwritten for performance reasons - create a fast path for byte strings" string isByteString ifTrue: [ self next: count putAllByteString: string startingAt: offset toStream: stream ] ifFalse: [ super next: count putAll: string startingAt: offset toStream: stream ] I TOTALLY get this. This is a whole bunch of very specific questions. But my ultimate goal is to take a deep dive into stream processing to figure this out. Thanks! ---- peace, sergio photographer, journalist, visionary Public Key: https://pgp.key-server.io/pks/lookup?op=get&search=0x69B08F58923AB3A2 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV @sergio_101@mastodon.social https://sergio101.com http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Hi, Besides the links James has sent, there's also https://github.com/ba-st/Docker-GemStone-64/ . It's still a bit in flux because we're not running production code in it yet, but we're using it in our projects for CI ( https://github.com/ba-st-actions/gs64-ci ) and the projects in https://github.com/ba-st are gaining support for GemStone 64 alongside Pharo.

Re: [ Security ] Accessing private information from Pharo image

by Richard O'Keefe

Back in the days when an entire department would share something like a VAX and think themselves lucky, the advance was never to let secrets *rest* in your address space any longer than you had to. Bring the secret into memory just the instant before you need it, use it, then scrub that area of memory. You might want to put the credentials on a thumb drive which is plugged in only when needed, I've generally found it better for environment variables to contain file names pointing to configuration files than to have then hold the configuration information directly.

One of the usualy ways especially on unix systems is to hand credentials in via the process environment. If you execute OSEnvironment current at: âSHELL' in a playground you should see somthing like â/bin/bashâ. So when starting the process you just need to specify the environment variables so that pharo can access it. If you use docker there is a way to specify that easily. Norbert

Dear Sergio, You are right that passwords and credentials should not be committed to source code. There are several alternatives available. If you are running the code on your own machine, logged as you, then I would just keep the credentials in ~/.ssh as a private key. Another place for the credentials might be something like /var/opt/MYAPP/myPrivateKey. In any case, ensure that you protect the key with 400 or 600 security (this assumes you are using Linux or macOS).

ESUG 2024 book the dates

by stephane ducasse

Hello The ESUG board decided the dates and location of the next ESUG conference ESUG 2024 will be at Lille from 8th to 11th July 2024. Notice that this year the conference will be on 4 days. The early rate registration will be 15 of April 2024. The IWST workshop will be chaired by G. Rakic and S. Ducasse.

Re: Removing and object from an OrderedCollection in the inspector

by Noury Bouraqadi

In the the collection's inspector (left), in the bottom pane (playground) evaluate : self removeAt: 4. "Replace 4 with the index of element you want to remove" I suggest you work more in a playground you open from the "Browse" menu. Here is an example of what you can do: someEvent := "Code to get the event to delete". myEvents := OrderedCollection withAll: {"Your events here"}. myEvents remove: someEvent Noury -- https://PharoJS.org On Jan 12 2024, at 11:15 pm, sergio ruiz <sergio.rrd(a)gmail.com> wrote: > > I am trying to remove some objects from an OrderedCollection in the inspector. > > I have class called Event.

Re: Updating objects in the inspector

by Noury Bouraqadi

Sergio, Welcome back to Pharo Smalltalk. The pane at the bottom of the inspector is a playground that has acces to the object instance variables. You can evaluate what ever expression you want. In your example, that would be name := 'New name' Noury -- https://PharoJS.org On Jan 12 2024, at 10:35 pm, sergio ruiz <sergio.rrd(a)gmail.com> wrote: > Hi, all. > > I have been away from Pharo/Smalltalk for several years, but I am coming back to it now.
