Yes but why ensureCreateFile then ? Why don't we juste create a message createFile as there is createFolder ? createFolder : create the folder createFile : create the file ensureCreateFolder : create the folder and its parents if necessary ensureCreateFile : create the file and its parents if necessary 2016-04-21 9:46 GMT+02:00 Peter UhnÃ¡k <i.uhnak(a)gmail.com>: > At least in unix creating files and folders are different operations > (mkdir/touch, rm/rmdir). > > And even though it may seem convenient I would argue that it will create > unintentional issues â if you have incorrect folder it will silently create > errornous structure on the disk instead of throwing error.

Re: [Pharo-users] ensureCreateFile

by Peter UhnÃ¡k

At least in unix creating files and folders are different operations (mkdir/touch, rm/rmdir). And even though it may seem convenient I would argue that it will create unintentional issues â if you have incorrect folder it will silently create errornous structure on the disk instead of throwing error. Imho overloading ensureCreateFile is bad. But there's nothing stopping you from extending AFR and adding an extra method: AbstractFileReference>>ensureCreateFileAndDirectory "Create if necessary a folder and file for the receiver." self parent ensureCreateDirectory. self ensureCreateFile Peter On Wed, Apr 20, 2016 at 6:16 PM, Denis Kudriashov <dionisiydk(a)gmail.com> wrote: > I would call error > > 2016-04-20 17:13 GMT+02:00 Valentin Ryckewaert < > valentin.ryckewaert(a)gmail.com>: > >> Hi, >> >> I would like to have your opinion about what you want ensureCreateFile to >> do. >> According to me ensureCreateFile should do the same thing as >> ensureCreateDirectory + create the file in the last directory given but in >> its implementation if the parents of this file doesn't exist we get an >> Exception. >> >> Is it wanted or an error? >> >> Valentin. >> > >

I tried clicking on the various buttons, and clicking action-clicking, and middle buttong click on the tab name ("Page"), without success (Pharo 5.0 50702). > > Finally, in Section 8.2 on versions of a method, my impression from > > reading the section was that it would always display all versions of a > > method, i.e. I have 24 versions of a package in my package cache, so > > expected to see each modification to each method in the package. > > However because I had switched to a new image and loaded the newest > > package, only the latest version was shown. > > > > In the setting you can change the package-cache location to use always > the same location even when you change of image.

Hi Pablo, Well, I tried to load the packages from your repositories, but I couldn't. First I tried to load all the packages in the repository via: Gofer it url: 'http://smalltalkhub.com/mc/pabloTesone/J2Inferer/main'; package: 'J2Inferer'; package: 'J2Profiler'; package: 'ConfigurationOfJ2Inferer'; load. But then I have this error: "This package depends on the following classes: SIRegister You must resolve these dependencies before you will be able to load these definitions: J2SilentSIRegister J2SilentSIRegister>>#fill" And when I try to load it via 'ConfigurationOfJ2Inferer loadBleedingEdge', and I got: 'Could not resolve: J2Inferer in C:\Users\diego\Desktop\pharo' How I am supposed to load them in my image? I am still a newbie in Pharo so I don't know how you are supossed to do it :P Cheers, Diego. 2016-04-19 4:11 GMT-03:00 tesonep(a)gmail.com <tesonep(a)gmail.com>: > Hi Diego, > Just yesterday I have added documentation explaining a bit how the > process is working in my Type Inferer, it works in a different way than > RoelTyper, but maybe you can get ideas of how enhance Roel's > > Any doubt please tell me. > > Pablo > > > On Tue, Apr 19, 2016 at 2:41 AM, Diego Orellana <dorellang(a)gmail.com> > wrote: > >> Hello, >> My smalltalkhub user is dorellang. >> >> Cheers. >> >> 2016-04-15 17:27 GMT-03:00 stepharo <stepharo(a)free.fr>: >> >>> Hello Diego >>> >>> Good initiative! >>> RoelTyper is not a Moose project.

Hello, Stephan. I uploaded the test and the fix (actually a workaround to prevent the method from exploding a throwing an error; basically the type information from block temporaries is omitted). So it works ok so far :) Cheers, Diego. 2016-04-19 10:01 GMT-03:00 stepharo <stepharo(a)free.fr>: > I added you. > Tell me if this is working. > > Le 19/4/16 02:41, Diego Orellana a Ã©crit : > > Hello, > My smalltalkhub user is dorellang. > > Cheers. > > 2016-04-15 17:27 GMT-03:00 stepharo <stepharo(a)free.fr>: > >> Hello Diego >> >> Good initiative! >> RoelTyper is not a Moose project.

Is there a way to tell > Pharo to save evaluated code to the changes file? (I admit to being > lazy and not trying to figure this one out myself yet). It looks like evaluated code is saved in the play-cache directory and accessible through the Spotter. Perhaps you could change the paragraph to something like: This is because all of the code that you write is saved in the .changes file, and expressions that are evaluated in the playground are saved to the play-cache. Expressions from the playground may be found using the spotter as described in section 2.11. (And then go on to describe how to recover code) Thanks, Alistair

I've also realised that I built all my changes on an older version of Tabular. :-( So, time to learn more about Monticello... Reading the Updated PbE is helpful, however I did notice one thing which doesn't match my experience. On page 150 it is discussing how you can't lose code... "This is because all of the code that you executed is saved in the .changes file. All of it! This includes one liners that you evaluate in a workspace, as well as code that you add to a class while programming." Should "workspace" be changed to "playground"? My experience has been that code evaluated in the playground is *not* saved to the changes file (Pharo 4.0 and 5.0). Is there a way to tell Pharo to save evaluated code to the changes file? (I admit to being lazy and not trying to figure this one out myself yet). Finally, in Section 8.2 on versions of a method, my impression from reading the section was that it would always display all versions of a method, i.e. I have 24 versions of a package in my package cache, so expected to see each modification to each method in the package. However because I had switched to a new image and loaded the newest package, only the latest version was shown. Re-reading the section, it does say that you can see each version that you save, however it might be worthwhile adding a sentence that explicitly states that only versions loaded into the image are shown (I guess it is actually versions in the changes file?).
