How do I ask the FileSystem to resolve a relative path?

by H. Hirzel

Hello This is a follow up question to 'How do I make sure a directory exists?' The answer to that question was dir := FileSystem workingDirectory / '..' / 'public'. dir ensureCreateDirectory. Now I want to create a writeStream. dir writeStream gives 'Unable to open file' It seems that I need to ask to resolve the relative path first. How does the proper code idiom look like? Regards Hannes

The fact that "workingDirectory" point to the folder from where Pharo was launched is only valid since Pharo 7. Before there was no distinction between workingDirectory and imageDirectory which caused problems when you wanted to script. > > So > > (FileSystem workingDirectory / '..' / 'public') ensureCreateDirectory > > > Worked fine. > > > Thanks to all! > > --Hannes > -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France

I note that 'workingDirectory' is the directory where Pharo is launched from. In my case it happens to be the same where the image is in but that cannot be assumed generally. So (FileSystem workingDirectory / '..' / 'public') ensureCreateDirectory Worked fine.

Operator priority :); unary messages `#ensureCreateDirectory have precedence over binary `#/` (FileSystem disk workingDirectory / '../public') ensureCreateDirectory. Also please note that the workingDirectory should be based on where Pharow as launched from, if you are looking for the image directory, then use the following FileLocator imageDirectory asFileReference Cheers, Peter On Sat, Mar 10, 2018 at 9:35 PM, H.

Re: [Pharo-users] How do I make sure a directory exists?

by H. Hirzel

Yes, #ensureCreateDirectory is available. I'd like to make sure a directory 'public' is available as a sibling directory of the working directory (the directory where the Pharo image is in) However FileSystem disk workingDirectory / '../public' ensureCreateDirectory does not work as FileSystem disk workingDirectory / '../public' is an instance of ByteStream. Seemingly there is no conversion to a directory object. I wonder what is needed in addition? On 3/10/18, Cyril Ferlicot <cyril.ferlicot(a)gmail.com> wrote: > On sam. 10 mars 2018 at 21:02, H.

How do I make sure a directory exists?

by H. Hirzel

Hello In Squeak and the dialect independent FileMan [1] there is FileDirectory assureExistence "Make sure the current directory exists. If necessary, create all parts in between" What is the equivalent Pharo method? BTW is there a cheat sheet for FileSystem operations in Pharo? Thanks in advance Hannes --------------------------------------------------------- [1] http://wiki.squeak.org/squeak/6333 https://github.com/mumez/FileMan FileMan provides an API to file and directory tasks. FileMan is a thin wrapper for various Smalltalk file libraries. It provides simple, portable interfaces for manipulating files and directories. ... Since 2015 FileMan is the default file library in Cuis Smalltalk.
