Re: [Pharo-users] Parser for javascript mongodb (json) notation selects

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@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 } } ] } )’

And you get the AST that you can play with (and transform into what you want):

Cheers, Doru

SmaCC ships with a JS parser. Please take a look at it.

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=)
