Rome

Rome is a tool that allows developers on Apple platforms to use Amazon's S3 as a shared cache for frameworks built with Carthage.

Get Rome

$ brew install blender/homebrew-tap/rome

The Rome binary is also attached as a zip to each release on the releases page here on GitHub.

Using Rome? Let me know by opening an issue and I will gladly add you to the user list.

Use Rome with fastlane

You can integrate rome into your fastlane automation with the fastlane plugin for rome.

The problem

Suppose you're working a number of frameworks for your project and want to share those with your team. A great way to do so is to use Carthage and have team members point the Cartfile to the new framework version (or branch, tag, commit) and run carthage update.

Unfortunately this will require them to build from scratch the new framework. This is particularly annoying if the dependency tree for that framework is big and / or takes a long time to build.

The solution

Use a cache. The first team member can build the framework and share it while all other developers can get it from the cache with no waiting time.

Workflow

The Rome's workflow changes depending if you are the producer (i.e. the first person in your team to build the framework) or the consumer.

Producer workflow

$ vi Cartfile # point to the new version of the framework
$ carthage update && rome upload

Consumer workflow

$ vi Cartfile # point to the new version of the framework
$ carthage update --no-build && rome download

$ vi Cartfile.resolved # point to the new version of the framework
$ rome download

Set up and Usage

First you need a .aws/credentials file in your home folder. This is used to specify your AWS Credentials.
Second you need a .aws/config file in your home folder. This is used to specify the AWS region.
Third you need a Romefile in the project where you want to use Rome. At the same level where the Cartfile is.

Setting up AWS credentials

Since version 0.2.0.0 Rome will expect to find credentials either as environment variables $AWS_ACCESS_KEY_ID and $AWS_SECRET_ACCESS_KEY or in a file at .aws/credentials. This aligns Rome behavior to other tools that use Amazon's SDK. See Amazon's blogpost on the topic.

In your home folder create a .aws/credentials like the following

[default]
aws_access_key_id = ACCESS_KEY
aws_secret_access_key = SECRET_KEY

this should look something like

[default]
aws_access_key_id = AGIAJQARMD67CE3DTKHA
aws_secret_access_key = TedRV2/dFkBr1H3D7xuPsF9+CBHTjK0NKrJuoVs8

these will be the credentials that Rome will use to access S3 on your behalf. To use configurations other than the default profile set the $AWS_PROFILE environment variable to your desired profile.

Selecting the AWS Region

In your home folder create a .aws/config like the following

[default]
region = us-east-1

To use configurations other than the default profile set the $AWS_PROFILE environment variable to your desired profile.

Romefile

The Romefile has three purposes:

Specifies what caches to use - [Cache] section. This section is required.
Allows to use custom name mappings between repository names and framework names - [RepositoryMap] section. This section is optional and can be omitted.
Allows to ignore certain framework names - [IgnoreMap] section. This section is optional and can be omitted.

A Romefile looks like this:

[Cache]
  S3-Bucket = ios-dev-bucket
  local = ~/Library/Caches/Rome/

[RepositoryMap]
  HockeySDK-iOS = HockeySDK
  awesome-framework-for-cat-names = CatFramework
  better-dog-names = DogFramework

[IgnoreMap]
  xcconfigs = xcconfigs

The Romefile is in the INI format

Cache section

This section contains the name of:

the S3 bucket you want Rome to use to upload/download. The key S3-Bucket is required.
the path to local directory to use as an additional cache. The key local is optional.

RepositoryMap

This contains the mappings of git repository names with framework names. This is particularly useful in case you are not using github and the "Organization/FrameworkName" convention.

Example:

Suppose you have the following in your Cartfile

github "Alamofire/Alamofire" ~> 4.3.0
github "bitstadium/HockeySDK-iOS" "3.8.6"
git "http://stash.myAnimalStartup.com/scm/iossdk/awesome-framework-for-cat-names.git" ~> 3.3.1
git "http://stash.myAnimalStartup.com/scm/iossdk/better-dog-names.git" ~> 0.4.4

which translates to the following Carftfile.resolved

github "Alamofire/Alamofire" "4.3.0"
github "bitstadium/HockeySDK-iOS" "3.8.6"
git "http://stash.myAnimalStartup.com/scm/iossdk/awesome-framework-for-cat-names.git" "3.3.1"
git "http://stash.myAnimalStartup.com/scm/iossdk/better-dog-names.git" "0.4.4"

but your framework names are actually HockeySDK, CatFramework and DogFramework as opposed to HockeySDK-iOS, awesome-framework-for-cat-names and better-dog-names.

simply add a [RepositoryMap] section to your Romefile and specify the following mapping:

[Cache]
  S3-Bucket = ios-dev-bucket

[RepositoryMap]
  HockeySDK-iOS = HockeySDK
  awesome-framework-for-cat-names = CatFramework
  better-dog-names = DogFramework

IgnoreMap

This contains the mappings of git repository names and framework names should be ignored. This is particularly useful in case not all your Cartfile.resolved entries produce a framework.

Some repositories use Carthage as a simple mechanism to include other git repositories that do not produce frameworks. Even Carthage itself does this, to include xcconfigs.

Example:

Suppose you have the following in your Cartfile

github "Quick/Nimble"
github "jspahrsummers/xcconfigs"

xcconfigs can be ignored by Rome by adding an IgnoreMap section in the Romefile

[IgnoreMap]
  xcconfigs = xcconfigs

Multiple Aliases

Since version 0.6.0.10 Rome supports multiple aliases for one map entry. Suppose you have a framework Framework that builds two targets, t1 and t2, Rome can handle both targets by specifying

[RepositoryMap]
  Framework = t1, t2

If ANY of the aliases is missing on S3, the entire entry will be reported as missing when running rome list [--missing]

Multiple aliases are supported in [IgnoreMap] too

Listing

Listing frameworks and reporting on their availability:

$ rome list
Alamofire 4.3.0 : +iOS -macOS +tvOS +watchOS
ResearchKit 1.4.1 : +iOS -macOS -tvOS -watchOS

Listing only frameworks present in the cache:

$ rome list --present
Alamofire 4.3.0 : +iOS +tvOS +watchOS
ResearchKit 1.4.1 : +iOS

Listing only frameworks missing from the cache:

$ rome list --missing
Alamofire 4.3.0 : -macOS
ResearchKit 1.4.1 : -macOS -tvOS -watchOS

Listing frameworks missing for specific platforms:

$ rome list --missing --platform watchos,tvos
ResearchKit 1.4.1 : -tvOS -watchOS

Forwarding a list of missing frameworks to Carthage for building:

$ rome list --missing --platform ios | awk '{print $1}' | xargs carthage build --platform ios
*** xcodebuild output can be found in ...

Note: list completely ignores dSYMs and Carthage version files. If a dSYM or Carthage version file if present) is missing, the corresponding framework is still reported as present.

Troubleshooting

Getting "Image not found" when running an application using binaries

Implicit dependencies of frameworks when using binaries are not copied over by Xcode automatically despite "Always Embed Standard Libraries" set to YES (see 56).

Here is an example with ReactiveCocoa, which depends on CoreLocation and MapKit. If ReactiveCocoa is built via Carthage or as a Xcode subproject, CoreLocation and MapKit are copied into the app's bundle. On the other hand, when using the binary, Xcode has no clue of that and does not copy the necessary frameworks even if "Always Embed Standard Libraries" is set to yes.

To fix that, add an explicit import statement to one of your files:

// Implicit ReactiveCocoa Dependencies

import CoreLocation
import MapKit
