another file reference question

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 |

Then I do not get why / is expecting a string and cannot accept a path.
Then I do not get why we have paths.

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 > <[hidden email]> 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 > |

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 <[hidden email]> wrote: > Hi Stef, > > On 2 February 2018 at 20:58, Stephane Ducasse <[hidden email]> 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 >> <[hidden email]> 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 Stef,
Assuming I understand what you're trying to do: This is broken out to hopefully make it clear what the steps are: | src srcPrefix dstPrefix dst | src := 'a/b/c/d.pi' asFileReference. srcPrefix := 'a' asFileReference. dstPrefix := 'result' asFileReference. dst := dstPrefix resolve: (src relativeTo: srcPrefix). dst At that point presumably you want: src copyTo: dst.

Tx alistair
Yes this is what I want. I tried to copy (before your post and I do not recall that copy was creating the intermediate folders).

Now what is the difference between / and resolve: because this is the
only difference with my code. I used path because it was the only way I could make sense. I will update the documentation :( this will be my cross.
