That's so cool plugin. Thank you very very much! But I'm a bit confused how to transform that tree into needed code f.e. into someCollection select: { '$or' -> { { 'name' -> { '$regex' -> 'test' . '$options' -> 'i' } asDictionary } asDictionary. { 'description' -> { '$regex' -> 'test' . '$options' -> 'i' } asDictionary } asDictionary } } asDictionary Could you help me, please? 2017-04-16 21:41 GMT+03:00 Tudor Girba <tudor(a)tudorgirba.com>: > Hi, > > Here is how to load it in Pharo 6: > Metacello new > smalltalkhubUser: 'JohnBrant' project: 'SmaCC'; > configuration: 'SmaCC'; > version: #'development'; > load > > Then you can do: > JSParser parse: 'db.SomeCollection.find( {$or: [ { name: { $regex: /test/i > } }, {description: { $regex: /test/i } } ] } )â > > And you get the AST that you can play with (and transform into what you > want): > > > Cheers, > Doru > > > On Apr 16, 2017, at 8:06 PM, Ð¥ÑÐ¸ÑÑÐ¸Ð½Ð° ÐÐ¸ÑÐ°Ð¹Ð»ÑÐº <chrismihaylyk(a)gmail.com> > wrote: > > Thank you very much! > But could you help me, please, to setup SmaCC into my Pharo? > > Your's faithfully, > Khrystyna Mykhailiuk > > 2017-04-16 20:57 GMT+03:00 Tudor Girba <tudor(a)tudorgirba.com>: > Hi, > > SmaCC ships with a JS parser.

Hi, Here is how to load it in Pharo 6: Metacello new smalltalkhubUser: 'JohnBrant' project: 'SmaCC'; configuration: 'SmaCC'; version: #'development'; load Then you can do: JSParser parse: 'db.SomeCollection.find( {$or: [ { name: { $regex: /test/i } }, {description: { $regex: /test/i } } ] } )â And you get the AST that you can play with (and transform into what you want): Cheers, Doru > On Apr 16, 2017, at 8:06 PM, Ð¥ÑÐ¸ÑÑÐ¸Ð½Ð° ÐÐ¸ÑÐ°Ð¹Ð»ÑÐº <chrismihaylyk(a)gmail.com> wrote: > > Thank you very much! > But could you help me, please, to setup SmaCC into my Pharo? > > Your's faithfully, > Khrystyna Mykhailiuk > > 2017-04-16 20:57 GMT+03:00 Tudor Girba <tudor(a)tudorgirba.com>: > Hi, > > SmaCC ships with a JS parser.

Re: [Pharo-users] Convert Literal array into Dynamic array

Thank you very much! Now I understand. Actually, I need this interpretation {7. 8. "f"} for writing parser of javascript queries which is used in MongoDB shell, to be able to execute this with MongoQuery Pharo class.

Now, perhaps what you want is to transform an Array into a Collection that accepts additions (that would be a âdynamicâ collection on Pharo)..

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.

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.
