I sorted out the problem by copying then renaming the class and categorising the copy.

Cool I will add it to my collection of solutions and I guess that this one is the fastest but I should check first :) Le 11/11/16 Ã 00:23, Henrik Nergaard a Ã©crit : > String>>isIsogram > > 1 to: self size -1 do: [ :ix | > (self > findString: (self at: ix) asString > startingAt: ix +1 > caseSensitive: false > ) ~~ 0 ifTrue: [ ^ false ] > ]. > > ^ true > > -----Original Message----- > From: Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] On Behalf Of Sven Van Caekenberghe > Sent: Thursday, November 10, 2016 11:10 PM > To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> > Subject: Re: [Pharo-users] Little challenges for a friday evening > > [ :string | string size = string asSet size ] value: 'Pharo'. > >>>> true > [ :string | string size = string asSet size ] value: 'Pharoo'. > >>>> false > String>>#isIsogram > ^ self size = self asSet size > > ? > >> On 10 Nov 2016, at 22:19, stepharo <stepharo(a)free.fr> wrote: >> >> Hi >> >> I'm checking how I would implement an isogram checker >> >> 'Pharo' isogram >> >>>>> true >> because it contains only single letter. >> >> I got a stupid bag drivent implementation but I will do another better and faster. >> >> Stef >> >> PS: after I will do anagram and pangram to have the family of gram checks (this is for a book). >> >> > > >

Hi Thierry, Le 11/11/2016 Ã 11:23, Thierry Goubier a Ã©crit : > Can you track down in your package versions where it stopped being > categorized properly? Is Nautilus unable to browse uncategorised class? I track the problem to March 2016, a few weeks after switching to Pharo4 (at least this class disappear from the package at this time). Then I did no uncategorise this class, may be another error from me, but odd as I was not working on that sector of the application. > What about converting the mcz to filetree, and reworking (updating by > hand the package structure)? May be, there are several way, but it is likely to be from a fresh image :( Thanks Hilaire -- Dr. Geo http://drgeo.eu

Hi Henrik, It was categorized since years, and now I can see it disappeared from the Monticello save, since maybe one year, glup! This is scarring as reloading code in fresh image will lead to missing code. Forcing recategorisation leads to another error, see log.
