Editing Package Properties

We've seen how any folder can be turned into a package with the init command. Initial properties can be set as named parameters to the init command.

init name="My Package" version=1.0.0

The init command can be called more than once on a package and it will keep existing properties and only overwrite the ones you specify.
Once you've created your box.json, you can edit the file directly, or there are other commands to help manage it programmatically.

Each of these commands support tab-complete that is dynamic based on what properties are currently in your box.json.

package show

The package show command can be used to out put any part of the box.json. You can specifiy any property name from your box.json.

Outputs package name and keywords

package show name
package show keywords

Nested attributes may be accessed by specifying dot-delimited names or using array notation. If the accessed property is a complex value, the JSON representation will be displayed

Outputs testbox runner(s)

package show testbox.runner

Outputs the first testbox notify E-mail

package show testbox.notify.emails[1]

Output the entire box.json

package show

using JmesPath with package show

package show jq:slug

# grab contributors and split each result by spaces
package show "jq:contributors|split(@,' ')" 

# get an array of all engine names
package show "jq:engines[].type"

# filter struct values and add in an additional value => { "myprop":"test", "name":"MyPackageName" }
package show "jq:{name:name, myprop:'test'}"

# return struct values in an array => [MyPackageName,2.4]
package show "jq:[name,version]"

package set

Any property in your box.json can be set from the command line with the package set command.

Set package name

package set name=myPackage

Nested attributes may be set by specifying dot-delimited names or using array notation. If the set value is JSON, it will be stored as a complex value in the box.json.

Set the repository type.

package set repository.type=Git

Set first testbox notify E-mail.

package set testbox.notify.email[1]="[email protected]"

Set multiple params at once by passing as many named parameters as you like.

package set name=myPackage version="1.0.0.000" author="Brad Wood" slug="foo"

Set a complex value as JSON.

package set testbox.notify.emails="[ '[email protected]', '[email protected]' ]"

Appending Complex Values

Objects and arrays can be appended to using the append parameter. This only works if the property and incoming value are both of the same complex type.

Add an additional contributor to the existing contributors array.

package set contributors="[ '[email protected]' ]" --append

Add an additional dependency to the existing dependencies object.

package set dependencies="{'cbcommons':'1.0.0'}"  --append

package clear

If you need to remove a property entirely from your box.json, use the package clear command. It also works on nested properties using "dot" or array notation.

Remove the package description entirely.

package clear description
