November 2018 - Pharo-users

Windows 10 double-click issue + solution

by John Kimber

Given the "What FP can learn..." demo, I decided to take another look at Pharo. Needless to say, I'm pleasantly suprised by the progress. The Launcher, in particular is impressive. Soon ran into an issue. On my pc under Windows 10, double-clicks would rarely select a word. Searched the Web, found some links but no real solution. Tried the following.... Under Mouse Properties>Activites: There's a setting for Double-click speed. Choosing the "Slow" value got double-clicks for Pharo working on my PC.

The added complexity of the Cog JIT would put it beyond my skills since the interpreter loop is cycled for every bytecode. In concept, add an instance variable to Process and increment that at the start of every interpreter loop. Can someone comment on the validity of that concept? cheers -ben

Re: [Pharo-users] split on space or -

by Nicolai Hess

split (or splitOn) are working on characters, but also on regex and blocks! 'Complementary metal-oxide semiconductor' splitOn: '-| ' asRegex. 'Complementary metal-oxide semiconductor' splitOn: [:c | c isSpaceSeparator or:[ c = $-] ]. Am Sa., 24.

What have you tried so far? There is a split method in pharo, with examples :) Am Sa., 24.

You need to add something like this in class String: rejectForAcronymsWords: aCollectionOfUnwantedWords " 'An example with an unwanted particle at the start of a sentence and also one in the middle' Â Â Â rejectForAcronymsWords: #('a' 'an' 'the' 'in' 'of' 'at' 'and') Â Â Â " ^self asLowercase substrings reject: [ :word |Â aCollectionOfUnwantedWords includes: word] ----------------- BenoÃ®t St-Jean Yahoo!
