@FromIRC

<RX14> please please don't do that

<RX14> that's no escaping at all

<RX14> use JSON.build

unreadable

@unreadable

Not sure if needed

Yeah I've used that before

require "json"

string = JSON.build do |json|
  json.object do
    json.field "name", "foo"
    json.field "values" do
      json.array do
        json.number 1
        json.number 2
        json.number 3
      end
    end
  end
end
string # => %<{"name":"foo","values":[1,2,3]}>

From IRC (bridge bot)

@FromIRC

<RX14> it's always needed

unreadable

@unreadable

In my case the data is queried from the database

not directly from the user

From IRC (bridge bot)

@FromIRC

<RX14> and where does the data in the db come from?

<RX14> and what if you make a mistake

Johannes Müller

@straight-shoota

data from the database might include special characters which need to be escaped in JSON

From IRC (bridge bot)

@FromIRC

<RX14> it's very little more effort to use JSON.build there

Johannes Müller

@straight-shoota

And it's probably even faster than concatenating strings...

@codenoid

hmm, https://play.crystal-lang.org/#/r/2j68

unreadable

@unreadable

I guess I'ma wrap the json builin

From IRC (bridge bot)

@FromIRC

<RX14> JSON.build { |json| json.object { key.zip(values).each { |key, value| json.field key, value } } }

unreadable

@unreadable

looks nice

Gabriel Torrecillas Sartori

@G4BB3R

@FromIRC

<RX14> you want something like this: crystal-lang/crystal-db#56
It does not works yet, right? I tried it and it gives an error "DB::Database#query_all' is expected to be invoked with a block, but no block was given"

From IRC (bridge bot)

@FromIRC

@G4BB3R, I'm a bot, bleep, bloop. I relay messages between IRC (#crystal-lang on chat.freenode.net) and here

<RX14> yes that PR is not merged yet

Rubi

@codenoid

it's a Valid JSON

but why, :worried:

From IRC (bridge bot)

@FromIRC

<RX14> because crystal play is broken

Rubi

@codenoid

oderlo@oderlo:/var/app/toped$ crystal build src/toped.cr && ./toped
Unexpected char '/' at 1:36441 (JSON::ParseException)
0x47c607: *CallStack::unwind:Array(Pointer(Void)) at ??

actually

From IRC (bridge bot)

@FromIRC

<RX14> why did you gsub ' out?

<RX14> that's so weird

Rubi

@codenoid

idk :O

From IRC (bridge bot)

@FromIRC

<RX14> it's entirely unneeded

Rubi

@codenoid

is i did it ?

Hanyuan Li

@hanyuone

Argh, does anyone on have any experience with libgen?

I don't know why my thing doesn't work

From IRC (bridge bot)

@FromIRC

<RX14> also you want to use sub not gsub @codenoid

Rubi

@codenoid

https://play.crystal-lang.org/#/r/2j6c

aahh

From IRC (bridge bot)

@FromIRC

<RX14> you want to remove the first instance of angular.callbacks._0( not every instance

<RX14> @codenoid ignore that error on crystal play

<RX14> it is nothing to do with your code

<RX14> it is broken

Rubi

@codenoid

not about crystal playground

but about json parser and my json value

From IRC (bridge bot)

@FromIRC

<RX14> Unexpected char '/' at 1:36441 is the correct error

<RX14> not that on in play.crystal-lang.org

Rubi

@codenoid

i dont find anything

From IRC (bridge bot)

@FromIRC

<RX14> it's most likely an escaping issue in the string

<RX14> yup

<RX14> you need a %q string

<RX14> so that backslash escapes are processed properly

<RX14> it's literally because you pasted it into a string literal
