Re: [Pharo-users] LGit_GIT_ERROR: Invalid version 0 on git_remote_callbacks on latest 64bit 6.1 image?

by Paulo R. Dellani

You need to configure Iceberg with the path of the SSH key files you are using to authenticate with gitlab as well as the passphrase to unlock the private key, I only got it working after that. Have your done that?

PharoLauncher directories

by stephan

I run into all kinds of issues with the directory structure used by the new PharoLauncher. pharo-local seems to be shared now for multiple images. That makes using configurations practically impossible as they are not expecting to have to deal with pre-downloaded older and newer monticello files. The missing sources files is less of a problem.

Re: [Pharo-users] Binary Decision Diagram Package in Smalltalk

by Steffen MÃ¤rcker

I see. How about the following (sketched) solution to avoid looping over all characters? It might be very well the case that you already considered (and dismissed) that path. A) Assumption In order to allow any meaningful matching, the input to the scanner is normalized according to the unicode spec. B) Abstraction Treat each character and character group of an regex as a set of intervals in the unicode code points. Lets call them "character tests" and lift the common set operations union, intersection and difference to them. C) Construct NFA NFA has potentially overlapping character tests at the transitions of each state. D) Construct DFA Given a product state s in the DFA and two transitions t1, t2 from the original NFA, add three new transitions to the DFA: - a transition labeled with the character test of t1 minus the character test of t2 - a transition labeled with the intersection of the character tests of t1 and t2 - a transition labeled with the character test of t2 minus the character test of t1 E) Extension Instead of sets of unicode intervals we could also use test-functions, e.g. blocks. Then, in step D), the set operations are translated to boolean operations: - difference t1 - t2 becomes: t1 && not t2 - intersection of t1 and t2 becomes: t1 && t2 This would allow to use optimized test functions, e.g., bdds, instead of relying on charcter tests only.

Soup bug(fix)

by Siemen Baader

Hi all, who maintains Soup, the HTML parser? Stef? It seems to auto-close <button> (and <a>) tags when nested inside another element. I wrote this test that fails: testNestedButton "this works with nested <div> tags instead of <button> and when there is no enclosing <div> at all. but here <button> is auto-closed." "a does not work either" | soup | soup := Soup fromString: '<div><button> <span>text</span> </button> </div>'. self assert: soup div button span string equals: 'text' ---- Where should I look to prevent Soup from auto-closing the tag, and where & how should I submit my fix? cheers, Siemen

The Watery theme is working in general but broken in many small details including the Spotter integration.
