Thanks alistair What I want to know is a different of paths between two paths so that after I can reproduce the structure under another folder. Example a/b/c/d.pi I should ''copy'' it into result folder and I should get result/b/c/d.pi now I compute the path What is the path of a/b/c/d.pi in a => b/c/d.pi and I should then 'copy' to result/b/c/d.pi On Fri, Feb 2, 2018 at 11:26 PM, Alistair Grant <akgrant0710(a)gmail.com> wrote: > Hi Stef, > > On 2 February 2018 at 20:58, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: >> Then I do not get why / is expecting a string and cannot accept a path. >> >> Then I do not get why we have paths. >> Stef > > Paths are intended to be internal, and not something you ever deal > with directly. > > I'm not sure I understand what you want to do, but maybe try replacing > #/ with #resolve:, e.g.: > > '/home' asFileReference resolve: 'user' asFileReference > " File @ /home/user" > > > or: > > '/home' asFileReference resolve: 'user' asFileReference path > " File @ /home/user" > > > Cheers, > Alistair > > >> On Fri, Feb 2, 2018 at 8:22 PM, Stephane Ducasse >> <stepharo.self(a)gmail.com> wrote: >>> HI >>> >>> I have the following scenario: >>> >>> '/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks/Booklet-AMiniSchemeInPharo/_result' >>> asFileReference / >>> 'book.pillar' >>> >>>>>> >>> "File @ /Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks/Booklet-AMiniSchemeInPharo/_result/book.pillar" >>> >>> ok it works. >>> >>> I want to update the contents of a target folder only if a file is >>> missing or too old compared to a source. >>> >>> The idea is that I have a target folder and I need to know if a file >>> located in the source tree should be copied under the target. >>> So I compute the difference from the root of the source to the file >>> and I want to apply this path to the target to check some file >>> properties. >>> >>> now I do not understand how I can get the following working: >>> >>> '/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks/Booklet-AMiniSchemeInPharo/_result' >>> asFileReference >>> / >>> >>> ('/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks/Booklet-AMiniSchemeInPharo/book.pillar' >>> asFileReference path) >>> relativeTo: ('/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks/Booklet-AMiniSchemeInPharo' >>> asFileReference path) >>> >>> >>> Stef >> >

HI I have the following scenario: '/PharoBooks/Booklet-AMiniSchemeInPharo/_result' asFileReference / 'book.pillar' >>> "File @ /PharoBooks/Booklet-AMiniSchemeInPharo/_result/book.pillar" ok it works. I want to update the contents of a target folder only if a file is missing or too old compared to a source. The idea is that I have a target folder and I need to know if a file located in the source tree should be copied under the target. So I compute the difference from the root of the source to the file and I want to apply this path to the target to check some file properties. now I do not understand how I can get the following working: '/PharoBooks/Booklet-AMiniSchemeInPharo/_result' asFileReference / ('/PharoBooks/Booklet-AMiniSchemeInPharo/book.pillar' asFileReference path) relativeTo: ('/PharoBooks/Booklet-AMiniSchemeInPharo' asFileReference path) You see relativeTo: should tells me the diff in terms of path between two paths.

Ah, Esteban's PR review tool is exactly what I was looking for. It works ! Still, please, please (Pavel) write down somewhere what you just explained to me, else it will eventually be lost. Docs needed (1) contribute to Pharo (we have that) (2) keep in sync once you have done (1) (we have that, but not about image side) (3) review pull requests of others (new, this email to start) Anyway, thanks for the answers. > On 5 Feb 2018, at 15:10, Pavel Krivanek <pavel.krivanek(a)gmail.com> wrote: > > 2018-02-05 13:54 GMT+01:00 Sven Van Caekenberghe <sven(a)stfx.eu>: >> Hi, >> >> With pull requests, it is relatively easy to see what changed in GitHub. >> >> Eg.

Re: [Pharo-dev] Reviewing Changes ?

by Esteban Lorenzano

the PR tool will create a branch for you and will to a pull of the changes. yes, PR tool will work on the remote destination of your PR (which is pharo-project/development for Pharo), but this is reasonable. So, *if* your origin remote is not âpharo-projectâ, you need to go to remotes tab and select âReview pull requestsâ on the appropriate remote.

Re: [Pharo-dev] Reviewing Changes ?

by Esteban Lorenzano

yes, thatâs a way. anther way is to use âPR toolâ : in menu, choose âGitHubâ, then âReview pull requestsâ¦â. You will need your github user/pass since this is using the github api. â¦ and of course, this can be loadable/testable or not, depending on the part of the system you will be loading (it is usually ok). But in general, it should work (I do not think many people has used this tool so it can fail).
