Hi,
Does anyone know how I can/should concatenate 2 FileReference paths ? Given /tmp/my-cache and a/b/data.txt I want to get /tmp/my-cache/a/b/data.txt in such a way that it is a correct, useable path. Next I want to do #ensureDirectory on the parent and write to the file. '/tmp/my-cache' asFileReference / 'a/b/data.txt' asFileReference does not work. '/tmp/my-cache' asFileReference / 'a/b/data.txt' works but is wrong internally. I can't figure out the semantics of #, TIA, Sven |
Apparently it is #resolve:
'/tmp/data-dir/' asFileReference resolve: 'a/b/c/file.txt' asFileReference Way too many methods on the public classes of FileSystem are undocumented.

Will you be adding that one? ;)

I did my best to comment what I could really understand.
Now as soon as somebody understand more he should have the reflex to add comments. I was always confused by resolve: Stef > Apparently it is #resolve: > > '/tmp/data-dir/' asFileReference resolve: 'a/b/c/file.txt' asFileReference > > Way too many methods on the public classes of FileSystem are undocumented. > > On 21 Jun 2013, at 16:31, Sven Van Caekenberghe <[hidden email]> wrote: > >> Hi, >> >> Does anyone know how I can/should concatenate 2 FileReference paths ? >> >> Given /tmp/my-cache and a/b/data.txt I want to get /tmp/my-cache/a/b/data.txt in such a way that it is a correct, useable path.

I know you did, but it is as you say: this should be done by someone who really understands the design. For example: I learned about #resolve: from comments at the Disk implementation level, not the Public API level where there are almost no commennts. I got into several loops using wrong methods, those should have been marked private I would guess.

For example: I learned about #resolve: from comments at the Disk implementation level, not the Public API level where there are almost no commennts. I got into several loops using wrong methods, those should have been marked private I would guess. I know this is sad but this is the case with most of the code of colin. I did my best to add comments but guessing is always more error prone and stupid trial and error. Anyway we will improve slowly. I do not understand why writing simple method comments is difficult to do when you write the code of the methods. Stef |
