Re: [Pharo-users] Error loading own project from GitHub with Metacello

Manfred, When you use github, you don't need nor do you want to use a ConfigurationOf. git manages the versions for you so you don't need to define versions in the ConfigurationOf. If you want versions for a git repository, use tags. You still need to specify load order and project dependencies. For an example you can look at[1] or download the baseline: Metacello new baseline: 'External'; repository: 'github://dalehenrich/external:master/repository'; get. No need to specify a repository in the baselineOf, since the repository is derived from the location of the Baseline itself.

Re: [Pharo-users] High precision arithmetic

by Werner Kassens

Hi Stephane, <g> it _is_ in scitalk, at the moment only in the #development version, but i'd guess, that will change in a while. Hi Pierre, the problem - as Stephane pointed out - is that ScaledDecimal essentially is a Fraction, which depending on which function you use can be transformed to Float, iow you _can_ loose precision with it, i'd be careful and look at the implementations of the functions you use in Fraction; as far as i can see, ScaledDecimals reason of existence is not really to make arbitrary precision calculations possible. otoh ArbitraryPrecisionFloat is a package, that is not really fast, but as precise as you want it to be (with the implemented functions). werner On 02/02/2015 09:43 PM, stepharo wrote: > we should move it to scitalk ;) > Le 2/2/15 17:51, Werner Kassens a Ã©crit : >> Hi Pierre, >> you will find an ArbitraryPrecisionFloat package at sqeaksource that >> works eg in pharo3 & 4: >> http://www.squeaksource.com/ArbitraryPrecisionFl.html >> werner >> >> > > >

One more thing, I am using a Pharo 30862 image on OS X to evaluate the code.

Hi, sorry for the unfinished email upfront. I accidentially hit the send button before I was finished... So here we go again: Some time ago I started a small Pharo based project but didn't want to announce it before I knew how to load it conveniently. For versioning I started using GitFileTree and pushed the code to GitHub together with a ConfigurationOf created with Versionner. Only after a more recent email from Kilon on this list I figured out that the project should be easily loadable with the following commands: Metacello new configuration:'HttpExplorer'; repository:'github://mkroehnert/httpexplorer:master'; get. Metacello new configuration:'HttpExplorer'; repository:'github://mkroehnert/httpexplorer:master'; load. Executing the first command succeeds and the ConfigurationOfHttpExplorer appears in the Browser. But when I try to execute the load command I get the following error (unfortunately I don't yet know how to copy a complete stacktrace): Error: Instances of UndefinedObject are not indexable This is a result from executing ZnClient>>getConnectionAndExecute where 'request url' returns the following address: http://:80/git@github.com:mkroehnert/httpexplorer.git/?C=M;O%3DD I guess that the error is probably in the ConfigurationOf but I am a bit lost as to where I should dig further. It would be great if anyone could point me in the right direction of where to look or tell what went wrong. Thanks in advance, Manfred

Hi, some time ago I started a small Pharo based project. For versioning I started to use GitFileTree and pushed the code to GitHub together with a ConfigurationOf created with Versionner. But only after a more recent email from Kilon on this list

spotter preview

by Tudor Girba

Hi, The Glamorous Team is happy to present a new feature in Spotter: preview (you toggle it with Cmd+p). We think this boosts the usefulness of the Spotter interface significantly. [image: Inline image 1] For more details, please take a look at: http://www.humane-assessment.com/blog/boosting-gtspotter-with-preview This is available in the Moose image, and it will soon be integrated in the Pharo one. Please let us know what you think. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
