[Pharo-project] how to get a string read stream from filesystem

by Tudor Girba

Hi, I am using Filesystem, and I would like to get a read stream that provides a string instead of bytes. If I do "aReference readStream", I get a FSReadStream which is a byte stream. To get to the string, I now do the ugly: "aReference readStream contents asString" Is there a cleverer way? Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

Re: [Pharo-project] editing a project description on ss3.gemstone.com

by Alexandre Bergel

I do not know the details of SSOverview. But on squeaksource.com, editing a project description allows one to enter code using a <pre> and </pre> tag. For example, the project description used on http://www.squeaksource.com/Versionner.html is -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "Versionner" is a French word that means handling versions. <pre> Gofer new squeaksource: 'Versionner'; package: 'ConfigurationOfVersionner'; load. ((Smalltalk at: #ConfigurationOfVersionner) project version: #development) load.</pre> -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I haven't seen a way on ss3.gemstone.com to enter code in the project description.

The project description is just sanitized text as you would do with a seaside html text: 'foo'. See SSOverview>>renderDescriptionOn: html html heading level2; with: 'Project Description'. html paragraph: self model information "<---" and SSDirectoryListing>>renderContentOn: html html heading level1; with: self title. html anchor url: self project fullHomepageUrl; with: self homepageUrlText. html paragraph: [ html withLineBreaks: self information ]. "<---" super renderContentOn: html. self renderConfigsOn: html. What would you suggest? I am open to suggestions. Best -Tobias

[Pharo-project] editing a project description on ss3.gemstone.com

by Alexandre Bergel

Hi! On squeaksource.com, the project description can contains code using the <pre>...</pre> tag, as in: <pre> Gofer new url: 'http://ss3.gemstone.com/ss/SPIRIT'; package: 'ConfigurationOfSpirit'; load. (Smalltalk at: #ConfigurationOfSpirit) project lastVersion load </pre> It seems this does not work with ss3.gemstone.com. Has this tag been replaced with something else?

Re: [Pharo-project] how should Pier file structures be serialized with Fuel?

No, the early Fuel version did not have substitution hooks. I wrote custom visitor code to do substitution during export/import. I want to now eliminate this custom code. > Let me see if I understand....PRFile has a reference to a file (on > disk). So what you want is to serialize not only the PRFile but also the > contents of the file? What I want is an equivalent copy a subtree of a Pier kernel, created in another Pier kernel, even if that subtree contains a PRFile. Having the serialized subtree fit in a single file would be easiest to manipulate.
