go-helpers development

The following instructions are useful during development.

Note: This has been tested on Linux and Darwin/macOS. It has not been tested on Windows.

Prerequisites for development

🤔 The following tasks need to be complete before proceeding. These are "one-time tasks" which may already have been completed.

  1. The following software programs need to be installed:
    1. git
    2. make
    3. go

Install Senzing C library

Since the Senzing library is a prerequisite, it must be installed first.

  1. Verify Senzing C shared objects, configuration, and SDK header files are installed.

    1. /opt/senzing/er/lib
    2. /opt/senzing/er/sdk/c
    3. /etc/opt/senzing

  2. If not installed, see How to Install Senzing for Go Development.

Install Git repository

  1. Identify git repository.

    export GIT_ACCOUNT=senzing-garage
export GIT_REPOSITORY=go-helpers
export GIT_ACCOUNT_DIR=~/${GIT_ACCOUNT}.git
export GIT_REPOSITORY_DIR="${GIT_ACCOUNT_DIR}/${GIT_REPOSITORY}"

  2. Using the environment variables values just set, follow steps in clone-repository to install the Git repository.

Dependencies

  1. A one-time command to install dependencies needed for make targets. Example:

    cd ${GIT_REPOSITORY_DIR}
make dependencies-for-development

  2. Install dependencies needed for Go code. Example:

    cd ${GIT_REPOSITORY_DIR}
make dependencies

Lint

  1. Run linting. Example:

    cd ${GIT_REPOSITORY_DIR}
make lint

Build

  1. Build the binaries. Example:

    cd ${GIT_REPOSITORY_DIR}
make clean build

  2. The binaries will be found in the ${GIT_REPOSITORY_DIR}/target directory. Example:

    tree ${GIT_REPOSITORY_DIR}/target

Run

  1. Run program. Examples:

    1. Linux

      ${GIT_REPOSITORY_DIR}/target/linux-amd64/go-helpers

    2. macOS

      ${GIT_REPOSITORY_DIR}/target/darwin-amd64/go-helpers

    3. Windows

      ${GIT_REPOSITORY_DIR}/target/windows-amd64/go-helpers

  2. Clean up. Example:

    cd ${GIT_REPOSITORY_DIR}
make clean

Test

  1. Run tests. Example:

    cd ${GIT_REPOSITORY_DIR}
make clean setup test

Coverage

Create a code coverage map.

  1. Run Go tests. Example:

    cd ${GIT_REPOSITORY_DIR}
make clean setup coverage

    A web-browser will show the results of the coverage. The goal is to have over 80% coverage. Anything less needs to be reflected in testcoverage.yaml.

Documentation

  1. View documentation. Example:

    cd ${GIT_REPOSITORY_DIR}
make clean documentation

  2. If a web page doesn't appear, visit localhost:6060.

  3. Senzing documentation will be in the "Third party" section. github.com > senzing-garage > go-helpers

  4. When a versioned release is published with a v0.0.0 format tag, the reference can be found by clicking on the following badge at the top of the README.md page. Example:

    Go Reference Badge

  5. To stop the godoc server, run

    cd ${GIT_REPOSITORY_DIR}
make clean
