Re: [Pharo-users] Pharo image freeze and "Alt-." has no effect

by Steven RÃ©mot

Thanks Stephane ! I still get the freeze sometimes, but it's still really random, I can't find a way to reproduce it for sure. I had much less freezes on Pharo 5 the moment I stopped dumping and recreating athens surfaces at each layoutUpdate, that's all... I tell you if I find how to make it freeze for sure on Pharo 5 and on the dev snapshot. Le dim. 16 avr. 2017 Ã 14:22, Stephane Ducasse <stepharo.self(a)gmail.com> a Ã©crit : > Steven > > welcome.

Parser for javascript mongodb (json) notation selects

by chrismihaylyk

Hello, friends! I'm creating MongoDBBrowser that have all CRUD operations and I need a parser that translates javascript queries to MongoDB into the queries (for making selects, inserts etc.) using MongoQuery class. For example, I have query db.SomeCollection.find( {$or: [ { name: { $regex: /test/i } }, { description: { $regex: /test/i } } ] } ) that is manually rewriting into someCollection select: { '$or' -> { { 'name' -> { '$regex' -> 'test' . '$options' -> 'i' } asDictionary } asDictionary. { 'description' -> { '$regex' -> 'test' . '$options' -> 'i' } asDictionary } asDictionary } } asDictionary But I need to have a parser that will do it automatically. Maybe there are already exist one? If not, how to write my own? Please help. Thanks a lot, Khrystyna=) -- View this message in context: http://forum.world.st/Parser-for-javascript-mongodb-json-notation-selects-t… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Steven welcome. I hope that you will make a great implementation. If you have a reproducible case where alt+ does not work we are interested.
