## Building Nim projects on Circle CI

Building your code on Circle CI is useful to check regressions against the master and devel branches of Nim.
Same for your code documentation.

Configure the build:

Under Test Commands >> Dependency Commands >> Pre-dependency commands:
[source,sh]
----
wget http://http.us.debian.org/debian/pool/main/n/nim/nim_0.16.0-1_amd64.deb
wget http://http.us.debian.org/debian/pool/main/o/openssl1.0/libssl1.0.2_1.0.2k-1_amd64.deb
sudo dpkg -i *_amd64.deb
----

Under Test Commands >> Test Commands >> Test Commands:
[source,sh]
----
# This will fetch Nimble dependencies
nimble build -y
nim c -r <mytest.nim>
----

Be aware that the available .deb packages will change over time.

## Building Nim projects on Circle CI v2.0 (Currently in Beta)

Circle CI are currently testing version 2 of their platform, where you can use Docker containers to perform builds. The following example is taken from the following guide and builds against the current Nim version on both Ubuntu and Alpine Linux: +https://www.euantorano.co.uk/posts/nim-circle-ci/[Continuous Integration for Nim using Circle CI]

[source,yaml]
----
version: 2
jobs:
  build:
    working_directory: /usr/src/dotenv
    docker:
      - image: nimlang/nim
    branches:
      only:
        - master
    steps:
      - checkout
      - run:
          name: test
          command: nim c -r tests/main.nim
  build_alpine:
    working_directory: /usr/src/dotenv
    docker:
      - image: nimlang/nim:alpine
    branches:
      only:
        - master
    steps:
      - checkout
      - run:
          name: test
          command: nim c -r tests/main.nim
workflows:
  version: 2
  build_and_test:
    jobs:
      - build
      - build_alpine

## Building Nim projects on Travis CI

Building your code on Travis CI is useful to check regressions against the master and devel branches of Nim.
Same for your code documentation.

Detailed guide, which the following example originates from: +
http://blaxpirit.com/blog/22/advanced-uses-of-travis-ci-with-nim.html[Advanced uses of Travis CI with Nim]

If you don't want to rebuild the Nim compiler you can instead install the .deb packages listed on the CircleCI guide above using https://docs.travis-ci.com/user/installing-dependencies[this config]
