panic: Only a pointer to struct can be unmarshaled from TOML

[dcwills]

I'm a newb to this project, and I think I'm following the instructions, but perhaps I'm missing something?

This code generates the error in the subject line:

bundle := i18n.NewBundle(language.English) bundle.RegisterUnmarshalFunc("toml", toml.Unmarshal) bundle.MustLoadMessageFile(path.Dir(os.Args[0]) + "/i18n/active.fr.toml")

The toml file originates from a goi18n extract.

In addition, the MustLocalize example on this page generates the same error:

Thank you in advance.

Just tagged 2.0.0.beta.1 so there may be some bugs. I will take a look

Hi, Did you upload a change? The MustLocalize example on: https://godoc.org/github.com/nicksnyder/go-i18n/v2/i18n#pkg-examples <https://godoc.org/github.com/nicksnyder/go-i18n/v2/i18n#pkg-examples> fails. Also, my toml file is generated by extract, so I assume it’s fine. the error is happening because the go-toml code does not like the var raw interface{} as struct def’n this code is parse.go::ParseMessageFileBytes() THANK YOU SO MUCH FOR THE RAPID RESPONSE. I’m an expert programmer with 30+ years, but a relative newcomer to go, so I’m not as helpful as I could be :{ Dean On Apr 17, 2018, at 8:51 AM, Nick Snyder <notifications@github.com> wrote: Closed #95 <#95> via #96 <#96>. — You are receiving this because you authored the thread.

You probably need to go get -u github.com/nicksnyder/go-i18n. If you are using a dependency manager then you will probably need to update the version it points to (although I haven't tagged a new release so you would need to reference by commit hash).

If you are still having issues, please post what your toml file looks like.

I’m pulling all the v2 stuff, as that’s what my code requires. #! /bin/bash pushd $(cd -P -- "$(dirname -- "$0")" && pwd -P) export GOPATH=`pwd` go get -u github.com/nicksnyder/go-i18n/v2/goi18n go get -u github.com/urfave/cli go get -u golang.org/x/text/language go get -u github.com/nicksnyder/go-i18n/v2/i18n go get -u github.com/pelletier/go-toml source build.cmd Your code example that fails: bundle := i18n.NewBundle(language.English) bundle.RegisterUnmarshalFunc("toml", toml.Unmarshal) bundle.MustParseMessageFileBytes([]byte(` HelloWorld = "Hello World!" `), "en.toml") bundle.MustParseMessageFileBytes([]byte(` HelloWorld = "Hola Mundo!" `), "es.toml") { localizer := i18n.NewLocalizer(bundle, "en-US") fmt.Println(localizer.MustLocalize(&i18n.LocalizeConfig{MessageID: "HelloWorld"})) } { localizer := i18n.NewLocalizer(bundle, "es-ES") fmt.Println(localizer.MustLocalize(&i18n.LocalizeConfig{MessageID: "HelloWorld"})) } So far, I’m using none of my own code. I recommend you forget about my code and debug your example on: The MustLocalize example on: https://godoc.org/github.com/nicksnyder/go-i18n/v2/i18n#pkg-examples <https://godoc.org/github.com/nicksnyder/go-i18n/v2/i18n#pkg-examples> My code is this: bundle := i18n.NewBundle(language.English) bundle.RegisterUnmarshalFunc("toml", toml.Unmarshal) bundle.MustLoadMessageFile(path.Dir(os.Args[0]) + "/i18n/active.fr.toml") The toml file is: [DownloadHelp] hash = "sha1-b8545b47f150949c26d19c9eb7fc55e855de432a" other = "télécharger paquet d'apm" [HelloPerson] hash = "sha1-5b49bfdad81fedaeefb224b0ffc2acc58b09cff5" other = "Bonjour {{.Name}}" Thank you On Apr 17, 2018, at 10:56 AM, Nick Snyder <notifications@github.com> wrote: You probably need to go get -u github.com/nicksnyder/go-i18n.

Examples are automatically run and verified as part of unit tests (https://github.com/nicksnyder/go-i18n/blob/master/v2/i18n/example_test.go), so there must be a difference between the example code and what you are actually running if it is failing for you.

[dcwills]

got it. You are using a different toml package than me. Not sure how it slipped into my code. now using: "github.com/BurntSushi/toml” instead of: github.com/pelletier/go-toml Thank you! Seems to work now.

Glad you were able to figure it out. Versioning dependencies (and declaring which dependencies a package depends on) is an active area of development in the Go community. You may be interested to read this: https://research.swtch.com/vgo-intro
