Re: [Pharo-users] Smacc how to test scanner

by Thierry Goubier

Hi Stef, I think it is possible. After compiling your parser and scanner classes, take your scanner class and create it on a stream stefScanner := StefScanner on: (ReadStream on: 'My test string for my parser'). Then each token will be retrieved with SmaCCScanner>>#next stefScanner next Regards, Thierry 2017-04-04 15:01 GMT+02:00 Stephane Ducasse <stepharo.self(a)gmail.com>: > Hi > > When writing grammar I would like to test the scanner. > And I would like to this without having to define a special rule (in > addition to the one of the language).

Re: [Pharo-users] FileReference / and parent

by Stephane Ducasse

Hi alistair We should target Pharo 70. Now it is great that you help improving the file frameworks. Could you open a bug entry? Do you have tests?

Smacc how to test scanner

by Stephane Ducasse

Hi When writing grammar I would like to test the scanner. And I would like to this without having to define a special rule (in addition to the one of the language). Is it possible to get access to the scanner and ask it to scan the stream? Stef

I can't use the get.pharo.org <http://get.pharo.org/> method on NixOS both because the binary won't be compatible and because I need all dependencies to be locked down with a known sha256.

Thanks for the fast response! Can you also recommend the best pharo-launcher image version to package? The stable one looks stale (lists Pharo 5.0 as "beta" for me) On Tue, 4 Apr 2017 at 08:45, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > in fact, I will promote a new stable soon, so Iâd recommend for now take > the master branch of https://github.com/pharo-project/pharo-vm > > Esteban > > > On 4 Apr 2017, at 07:01, Luke Gorrie <luke(a)snabb.co> wrote: > > Questions! > > Where can I find the source code for the latest stable Linux/unix VM for > Pharo 5.0?

in fact, I will promote a new stable soon, so Iâd recommend for now take the master branch of https://github.com/pharo-project/pharo-vm <https://github.com/pharo-project/pharo-vm> Esteban > On 4 Apr 2017, at 07:01, Luke Gorrie <luke(a)snabb.co> wrote: > > Questions! > > Where can I find the source code for the latest stable Linux/unix VM for Pharo 5.0?

Recommended stable Pharo 5.0 VM for Linux users?

by Luke Gorrie

Questions! Where can I find the source code for the latest stable Linux/unix VM for Pharo 5.0? I want to package it for a Linux distribution (NixOS). Currently I am confused: The release tarballs at http://files.pharo.org/vm/src/vm-unix-sources/blessed show the latest non-Spur version being 2016-02-18. The github repo at https://github.com/pharo-project/pharo-vm has a tag Pharo50-stable on commit b8ec25a which dates from 2016-05-04. (Is this tag immutable or does it move around?) The URL for downloading binaries (get.pharo.org/vm50) does not seem to say anywhere what version it is downloading, and it was not obvious to me from downloading the binary and inspecting it with 'strings' either (it's not for my distro so I can't just run it with '--version'). Help would be appreciated! Great if somebody could also tell me under what circumstances the spur VM is preferred to the non-spur VM.
