[Pharo-users] [ANN] Phoedown - Markdown to HTML
Hi all, I've published Phoedown, an FFI to hoedown, the standards compliant, fast, secure Markdown processing library written in C. - https://github.com/PierceNg/Phoedown - https://github.com/hoedown/hoedown A simple example: | md | md := (FileSystem memory / 'somefile.md') writeStreamDo: [ :ws | ws nextPutAll: ' ```smalltalk Transcript show: ''Happy New Year!''; cr ``` ' ]; contents. HdHtmlRenderer new setMarkdownExtension: HdMarkdownExtensions FencedCode; setMarkdownExtension: HdMarkdownExtensions NoIntraEmphasis; render: md This is the output: Transcript show: 'Happy New Year!'; cr Pierce

I’m loving all the little utility libraries coming out (and appreciate the write ups on how things are done). I’m curious why you chose to use ffi for this one in particular as it would seem to be quite straightforward to do it all in native Smalltalk (not to down play your integration in any way of course). Was performance a big thing? Or was it simply relying on others to keep it up to date?

Re: [Pharo-users] why is masses not found?
--- Begin Message --- Hello, I have it now working but as you said there is a lot of code smells and my exact question is how to get rid of them. solution | computer | computer := self new. computer readRam: computer masses. computer patchRam: 1 value: 12. computer patchRam: 2 value: 2. computer processData: computer ram. computer at: 0 this is now a class method but I need a lot the computer variable. here you can find the whole code under intComputer class. Op 31-12-2019 om 19:29 schreef Sean P. DeNigris: Pharo Smalltalk Users mailing list wrote when I call on the class side the method which should reed the masses which are on the instanc side , the masses cannnot be found. IntComputer class >> solution | computer ram | computer := self new. computer readRam: masses. ... In your code above, you are not actually "calling a class-side method" (which BTW in Smalltalk the term is "sending a message", an important philosophical distinction if you want to grok Smalltalk), but referring to a class-side instance variable named "masses". The clue to this would have been that when you tried to compile the method, a dialog came up telling you about the undeclared variable. You seem to have clicked through choosing to create a variable, which you can now see in the class-side class definition: IntComputer class instanceVariableNames: 'masses' Probably you forgot to add "computer" before "masses", like so: `computer readRam: computer masses.` For future exploration, there are some design smells in your code, but it seems like you're currently at the "get it to work" stage, so it seems premature to dive into them here. NB: It will be much easier to help you in the future, if you include both of the following in your questions: 1. the exact error 2. "steps to reproduce" IOW in this case, something like: "I'm seeing '#splitOn: was sent to nil' from IntComputer class>>#readRam:. To reproduce, do `IntComputer solution`" This way we don't have to go hunting for an entry point, which will stop many (busy) people from even trying! - Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html --- End Message ---

Also I saw hoedown's wiki page on bindings and thought I'd put Smalltalk on the map there. https://github.com/hoedown/hoedown/wiki/Bindings Pierce
