Is there a file selector in Pharo

by David Pennington

I am moving to Pharo from VisualAge Smalltalk as I am now using an M1 MacBook. I am building software to manage our home accounts and to do this, I download each day a text file from my bank that contains about 1 monthâs worth of transactions. In VAST, I use a FileSelector that opens a window and enables my to navigate to the Downloads folder and lets me select the current transaction file. This gives me the path to the file making it simple for me to open and parse it. Is there a similar file selector window that I can use in Pharo? I can see how to open the Glamour browsers but not how to extract the path. Can anyone help please? David Totally Objects

Re: Pharo as a development environment for TiddlyWiki target/deployment platform

by Offray Vladimir Luna CÃ¡rdenas

I'm now using the Markdown plugin recommended by Nicolas[1], instead of the GFM plugin as It works better and supports transclusion. It's based on Remarkable so I think that it would be able to support no only transclusion but macros, so we could have the best of both worlds (now I'm mixing TiddlyWikis native WikiText syntax for macros and advanced features and using Markdown plugin for "legacy" content coming in this format).

Headless VM crashing on viewing class side methods

by kmo

I get an illegal instruction VM crash when trying to use the latest headless VM to view class side methods. I download the image and VM like this - curl https://get.pharo.org/64/90+vmHeadlessLatest | bash I open the image with ./pharo-ui Pharo.image I open a system browser and pick a class I click to view class side methods and crash! I'm using Xubuntu 20.04. I've tried this on two computers both running Xubuntu 20.04. Same thing. It's perhaps no coincidence that I also get an illegal instruction crash if I try to load the pharo GTK bindings. Does this mean that the headless VM has a serious problem with some chip sets? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Request for a #Magritte channel in Discord Pharo server

by Sanjay Minni

Do you think we could have a #Magritte channel in Discord Pharo Server I am working on it for my application and getting stuck and want to avoid flooding messages here. It could mean make or break in adapting Magritte. Magritte ML itself is inactive ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

I plan to have a look at it and implement a backend in pharo for tiddlywiki but time is really sparse right now. So I get back to you when I have something. And a way to improve the usage of markdown in the tiddlers would also be something good.

Re: join

by StÃ©phane Ducasse

Do not care about the title. What I suggest is that you send a new email With FFI in the title and you expose what you did before and what does not work anymore in plain text. Joining the code is nice but you should not force people to lose their time trying to understand what is YOUR problem. So you should always understand that nobody is paid to reply to your questions so the point is how to help people to help you.

Hello everybody! >From the very beginning I stepped - misnamed the topic, I thought to join the mail subscription (by running the join command), but I was already subscribed. I don't know how to rename this forum post, if it can be renamed then its name should be "FFIStructure questions". I am trying to run my C library on Pharo. Once upon a time I ran a test C function on Pharo, and with the help of the forum, it worked. But even FFI has changed since then, and I'm trying to master it from small to large. An attempt to determine the C structure failed and an error was received. Posts above, this was my attempt to briefly describe this error, or to get the direction of my further movement, if I was mistaken. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
