Embedding information at compile time.

[Pomba Magar]

Newbie alert!

I'm building a cli for learning dart and i wanted to embed some information from `pubspec.yaml` file and git output to my executable but i can't seem to find a good solution nor comprehensive information to do so, maybe i need to step up my googling skill.

Anyways, what i want to do is grab `name`, `version` & `description` from `pubspec.yaml` file and output them when certain flags are passed to the cli.

Eg:

```

app --help

# output

<app name> <version>+<git rev-parse --short HEAD>

<description> 

// other stuffs

```

Closest thing i came across was https://github.com/kevmoo/build_version but it doesn't have all the things i need.

Any help is greatly appreciated.

Hi,

What I would do is parse the pubspec.yaml file (I'm sure there's a pubspecparser package on pub.dev), and write yourself a Dart file with that info in it.

as an example:

```dart

void main() {

  final pubspec - parsePubSpec(); // However you do that.

  final code = "const name = '${pubspec.name}';\nconst version = '${pubspec.version}';\nconst description = '${pubspec.description}';

  File('bin/metadata.dart').writeAsStringSync(code);

}

```

Now you can include that file in your code. Just make yourself a batch file / shell script that generates the code before compiling your app.

HTH,

Take care,

Chris Norman

You could look into https://pub.dev/packages/build_version . It only supports the version, but I guess the name of your app won't change so often...
