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:

wget http://http.us.debian.org/debian/pool/main/n/nim/nim_0.18.0-2_amd64.deb
wget http://http.us.debian.org/debian/pool/main/o/openssl/libssl1.1_1.1.0h-4_amd64.deb
sudo dpkg -i *_amd64.deb

Under Test Commands >> Test Commands >> Test Commands:

# 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 using choosenim

choosenim allow picking fixed Nim versions or updating to the last stable or devel version

Use this .circleci/config.yml

---
version: 2
jobs:
  build:
    machine: true
    steps:
      - run: echo 'export PATH=~/.nimble/bin:$PATH' >> $BASH_ENV
      - checkout
      # Reuse cached Nim compiler
      - restore_cache:
          key: compiler-0002
      - run:
          command: |
            if [ -f ~/.nimble/bin/choosenim ]; then
              echo "Updating Nim using choosenim"
              choosenim stable
            else
              echo "Installing choosenim and Nim"
              wget https://raw.githubusercontent.com/dom96/choosenim/master/scripts/choosenim-unix-init.sh
              sh choosenim-unix-init.sh -y
            fi
      - save_cache:
          key: compiler-0002
          paths:
            - ~/.nimble
            - ~/.choosenim
      - run:
          command: |
            nimble build -y
            # add here your tests

Building Nim projects on Circle CI v2.0 using Nim Devel

Create .circleci/config.yml as:

version: 2
jobs:
  build:
    machine: true
    steps:
      - run: echo 'export PATH=./Nim/bin:$PATH' >> $BASH_ENV
      - checkout
      # Reuse cached Nim compiler
      - restore_cache:
          key: compiler-0000
      - run:
          command: |
            if [ -d Nim ]; then
              cd Nim
              git fetch
              if [ "$(git rev-parse HEAD)" == "$(git rev-parse @{u})" ]; then
                echo "Nim is up to date"
                build_nim=false
              else
                echo "pulling new Nim commits"
                build_nim=true
                git pull
              fi
            else
              echo "cloning Nim for the first time"
              build_nim=true
              git clone --depth 1 https://github.com/nim-lang/Nim.git
              cd Nim
              git clone --depth 1 git://github.com/nim-lang/csources.git csources
              cd csources
              sh build.sh
              cd ..
            fi
            if [ "$build_nim" = true ]; then
              ./bin/nim c koch
              ./koch boot -d:release
              ./koch tools
            fi
      - save_cache:
          key: compiler-0000
          paths:
            - Nim
      - run: nimble build -y
      - run: nim c -r <mytest.nim>
      - store_artifacts:
          path: test-reports/
          destination: tr1
      - store_test_results:
          path: test-reports/

Building Nim projects on Circle CI v2.0 with Docker

On Circle CI 2.0 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: Continuous Integration for Nim using Circle CI

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:
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 this config

You may encounter an issue with Sourceforge download and download just a webpage. In that case replace the generic URL by a direct link into a mirror like 'https://ayera.dl.sourceforge.net/project/mingw-w64/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-win32/seh/x86_64-4.9.2-release-win32-seh-rt_v4-rev4.7z'
