Roeloff, Is this for the Advent of Code 2018? The easiest way is to read the input file...Â Then, I can guide you from there!Â ;) ----------------- BenoÃ®t St-Jean Yahoo!

Re: [Pharo-users] Iceberg + BaselinOf + Metacello - how to manage interdependencies ?

by Hilaire

Hi Ichi, If you are learning Pharo I suggest you to not follow this way for now as it may result in cognitive overload and frustration. If you just want to save your code on some repo, use Metacello to create a tonel repository, then do code revision the way you use to do it (command line, third party GUI application). Your workflow will be: 1. Create a tonel report from Monticello: click on '+Repository' and chose tonel://, then select the direcotory in your host to save the code. 2. On this repo do Add to package to add your code (hope it works in released P7, does not on my Pharo7.0-32bit-0c5ade3). 2. Do the code versioning in the way you use to do it and with the tool you want. (git, svn, bzr, CLI, GUI) 3. Each time you want to save code change, go to Monticello and save dirty package 4. make the commit with your versioning system Hilaire Le 01/12/2018 Ã 12:10, Ichiseki a Ã©critÂ : > Hi, > You are not alone. > I have the same impression that Metacello+Git+Iceberg is something very > difficult to grasp. > It is getting hard to keep the pace with a constant evolving Pharo system. > best > ichi -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] How to take care that the + before a number is ignored

by Hilaire

Hi Roelof, Two problems: 1. + is a symbol so compare it to #+ 2. A false case is needed to return the untouched sum, otherwise it truns to nil #(+1 -8) inject: 0 into: [:sum :each | each ~= #+ ifTrue: [sum +Â each] ifFalse: [sum]] . Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] UFFI and opaque(ish) types

by Alistair Grant

Hi Phil and Esteban, Thanks for your replies. I've realised that I badly worded my question. By "opaque" I meant that it is difficult to determine the underlying type of the variables, but I still want to be access the values of typeA and typeB in my example structure. Phil, I had a look through your XMPP code, if it does show an example of actually retrieving a structure member such as "typeA" in my example, my apologies and please let me know where it is. Thanks again, Alistair On Fri, 30 Nov 2018 at 23:46, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > > On 30 Nov 2018, at 19:50, phil--- via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > From: "phil(a)highoctane.be" <phil(a)highoctane.be> > Subject: Re: [Pharo-users] UFFI and opaque(ish) types > Date: 30 November 2018 at 19:50:03 CET > To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> > > > Inherit from FFIOpaqueObject > > + initialize TypeMap > > I have a few here: > > https://github.com/Pharophile/XmppTalk > > https://github.com/Pharophile/XmppTalk/tree/master/packages/XmppTalk-Extern… > https://github.com/Pharophile/XmppTalk/blob/master/packages/XmppTalk-LibStr… > > HTH > Phil > > > Yes, as he says/shows :) > > Esteban > On Fri, Nov 30, 2018 at 2:39 PM Alistair Grant <akgrant0710(a)gmail.com> wrote: >> >> How are opaque(ish) types normally handled in UFFI (or FFI)? >> >> E.g. if I want to use libstuff which defines the following structure: >> >> struct stuffstruct { >> typeA a; >> typeB b; >> } stufftype; >> >> >> I might know they're integers, but not the size, signed vs. unsigned, >> etc. >> >> The definitions of typeA and typeB are buried in multiple layers of >> header files, dependent on #if tests, can be different sizes on >> different platforms (e.g. Linux vs. MacOS), etc.? >> >> Is this documented somewhere? >> >> Thanks, >> Alistair

Unlikely. OpenSmalltalk VM's single source code base is used to build VMs for several different Smalltalk-like languages. Pierce
