# Catmandu::Fix::Datahub::Util(3pm)

Utility functions and generic fixes developed for the Datahub project

## NAME

Catmandu::Fix::Datahub - Utility functions and generic fixes developed for the Datahub project

## SYNOPSIS

```
  use Catmandu::Fix::Datahub::Util;
```

## DESCRIPTION

```
  use Catmandu::Fix::Datahub::Util;
```

- "declare\_source($fixer, $var, $declared\_var)"

  For an item `$var`, which is a path (as a string) in a Catmandu fix, assign the value at the path to `$declared_var`, which is a variable that was previously declared in the fix code:

  ```
    my $f_var = $self->fixer->generate_var();
    $code .= "my ${f_var};";
    $code .= declare_source($self->fixer, 'foo.bar', $f_var);
  ```

- "walk($fixer, $path, $key, $h)"

  Walk through a `$path` (as an arrayref) until at `$key`. Assign the value of `$key` to `$h`. `$h` must be declared in the fix code.

  ```
    my $f_var = $self->fixer->generate_var();
    $code .= "my ${f_var};";
    $code .= walk($self->fixer, ['foo', 'bar'], $f_var);
  ```
