    Hello everyone. Can anyone contribute to spf13/viper? Don't see a contributing.md and am just wondering if anyone will actually look at PRs and merge them

    Is this project still maintained? :S
    Márk Sági-Kazár
    @sagikazarmark
    Hi Pedro! Yes, anyone can contribute. Yes, the project is maintained, but it's an open source project, so efforts spent on it is limited

    @madiganz I merged the linked PR.

    Hey guys. I am not sure this is the correct place for this but....

    I am using Viper to manage environment variables for a web app. It works perfectly if I run in normally....

    So the web app reads a couple of values from the environment using AutomaticEnv() and a couple of calls to GetString().

    If I package this up into a docker container viper will not be able to grab the env values it would if running outside the docker container. I know the environment variables are getting set. I can exec into the container see it.

    I tried switching to os.Getenv(). That call is able to pull in the values.

    Any ideas what's broken?

    Hi
    I made PR #760 for read only view using separated interface. It also have support for sub config with environment variables support (fix #643)

    @sagikazarmark it just seems to take for ever to get things merged. Maybe the people responsible for the repo should find others to help maintain the repo so it doesn't take 3 months to get PRs merged

    @sagikazarmark
    @ivybridge-3c33 I answered to your issue. TL;DR since you read in the config in main and the variable is evaluated before main is executed, this won't work. You have to fetch data from Viper after you read in the config file.

    Hello guys,
    Maybe I found a bug, but I'am not sure...

    I just want to write a config with mapstructure annotations on it...
    Struct:

        type Person struct {
            Age    int    `mapstructure:"a"`
            Gender string `mapstructure:"g"`
            Family string `mapstructure:"f"`
            Name   string `mapstructure:"n"`
        }

    The write method to write a config file:

    import (
        "bytes"
        "github.com/spf13/viper"
        "gopkg.in/yaml.v2"
    )
    
    func WriteConfig(configInstance interface{}, filePath string,) error {
    
        v := viper.New()
    
        b, err := yaml.Marshal(&configInstance)
    
        if err != nil {
            return err
        }
    
        defaultConfig := bytes.NewReader(b)
        v.SetConfigType("yaml")
    
        if err := v.MergeConfig(defaultConfig); err != nil {
            return err
        }
    
        return v.WriteConfigAs(filePath)
    }

    The result for yaml or json is always:

    {
      "age": 48,
      "family": "Family-Name",
      "gender": "m",
      "name": "Name"
    }

    yaml

    age: 48
    family: Family-Name
    gender: m
    name: Name

    The mapstructure annotation are not respected..
    Do I make something wrong here???

    btw. I am using the latest version from viper 1.6.1
    Márk Sági-Kazár
    @sagikazarmark
    yaml.Marshal won't respect mapstructure tag. Either use yaml tag in mapstructure as well (you can do that by configuring mapstructure), or first marshal your config to a map using mapstructure and then marshal that to yaml.

    What does someone have to do in order to have Default Flag -> Env -> CliFag work with cobra/ viper?
    My Cobra Flags never get bound to viper.GetString(configKeyClientKeyPath) ever after running
            flags.String(longOpt, defaultValue, description)
            config.ViperBindPFlag(key, flags.Lookup(longOpt))
            viper.SetDefault(key, defaultValue)

    Hi guys, is there an any method to check that all params in config structure was set in .yaml file ?

    Hello folks ! I have config file and structs that look like : https://pastebin.com/dMLNS7XN. I'm usingWithEnvPrefix("MYPREFIX") and WithAutomaticEnv(true) when loading the config. I absolutely need the env vars to have the priority over by config, but i don't know how my env var should be named, as my config is not flag, but contain array and nested key/vals.
    For a flat config, i know that if my config os named host, my env var should be named MYPREFIX_HOST
    But for such nested array config, i don't know. Thanks a lot.
    Márk Sági-Kazár
    @sagikazarmark
    You don't actually have arrays in your example config though.
    Just maps
    You can set a key name replacer and replace dots with underscores
    Then you can use MYPREFIX_LEVEL1_LEVEL2
    Abdelkader Bouadjadja
    @medinae
    Not arrays sorry, but i meant nested configs with multiple levels.
    Excellent, thanks a lot.

    Hi .. I have recently started working on cobra, can someone help me to know how to read a custom yml from cobra command line using viper.

    How do you guys share one viper instance to the multiple packages?

    When using viper.AutomaticEnv() is there a way to get env variable to display in the help along with each option automatically?
    Darragh Bailey
    @electrofelix
    I've used the following code to handle this, but seems like something that would be nice to enable automatically:
        RootCmd.PersistentFlags().VisitAll(func(f *pflag.Flag) {
            envKey := strings.ToUpper(replacer.Replace(f.Name))
            f.Usage = fmt.Sprintf("%s [env: %s]", f.Usage, envKey)
        })

    Which viper.Get method should I use to retrieve JSON from a YAML config?

    Hi Vipers!!!
    Im reading an INI file and I want to extract the sections names
    ie:

    [section 1]
    param1=foo1
    param2=bar1
    
    [section2]
    param1=foo2
    param2=bar2
    
    ......
    .......

    is this possible with viper!?

    I need to get a map like ["section1","section2" ....]

    Which viper.Get method should I use to retrieve JSON from a YAML config?

    did you tried with viper.GetString("path.to.your.json") ?
    then parse with viper again

    Hi guys, the signature of the MergeConfigMap will return an "error", but when I'm looked into the source code, I found that this method just return a nil error. Is there a way to make it return an error when the merge procedure is wrong?

    Hey guys, really small question here but in the README of viper, I don't see any documentation as to how to write to the the config file. I understand that there is the viper.WriteConfig() but what I am wishing to do is something like:

    viper.WriteConfig("key.key", "val")

    is there a semantic approach to staging changes to the config file before viper.WriteConfig() ?

    Hey all - i created this issue before noticing this IRC - got a small trouble shooting that would be great to have some help on - trying to get the envVar overrides to be in all underscores rather than periods - am i missing something obvious? spf13/viper#1029
