| <p>This section describes the Go environment and how to setup a Go |
| workspace. If you already have a Go workspace for your other Go |
| projects, you can skip this step and proceed to Step 3.</p> |
| <p>Go provides an environment to compile Go code, construct Go packages, |
| and import Go code. You will use Go commands to import the newt or |
| newtmgr package repository into your local Go environment. The Go |
| language environment dictates a specific directory structure, or |
| workspace in Go parlance. It must contain three sibling directories with |
| the names <strong>src</strong>, <strong>pkg</strong> and <strong>bin</strong>:</p> |
| <ul class="simple"> |
| <li><p>src contains Go source files organized into packages (one package per |
| directory)</p></li> |
| <li><p>pkg contains package objects</p></li> |
| <li><p>bin contains the Go application executables that Go builds and |
| installs.</p></li> |
| </ul> |
| <p>The <strong>GOPATH</strong> environment variable specifies the location of your |
| workspace. To setup this workspace environment, create a <strong>dev</strong> |
| directory and then a <strong>go</strong> directory under it. Set the GOPATH |
| environment variable to this directory where you will clone the newt and |
| newtmgr repositories.</p> |

| <p>This section shows you |
| how to rebuild the newt and newtmgr tools with the latest updates from |
| the master branch or after you have made changes in your branch.</p> |
| <p>Here is the general procedure to rebuild either the newt or newtmgr |
| tool. The only difference is the directory where you will be executing |
| the commands from. You will need to repeat the procedure to rebuild both |
| tools.</p> |
| <ol class="arabic simple"> |
| <li><p>Change to the directory where the local Git repository for the tool |
| is installed.</p></li> |
| <li><p>Pull the latest changes from the master branch. If you made changes |
| you will need to rebase with <strong>origin master</strong> (See |
| <span class="xref std std-doc">faq</span>).</p></li> |
| <li><p>Build and install the tool.</p></li> |
| </ol> |
| <p>Change to the directory where the source for the tool is installed.</p> |
| <p>For the <strong>newt</strong> tool:</p> |
| <div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$ </span><span class="nb">cd</span><span class="w"> </span><span class="nv">$GOPATH</span>/src/mynewt.apache.org/newt/newt |
| </pre></div> |
| </div> |
| <p>For the <strong>newtmgr</strong> tool:</p> |
| <div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$ </span><span class="nb">cd</span><span class="w"> </span><span class="nv">$GOPATH</span>/src/mynewt.apache.org/newtmgr/newtmgr |
| </pre></div> |
| </div> |
| <p>After you change to the specific tool directory, get the latest updates |
| from the master branch. If you made changes and need to rebase with the |
| origin, add the <code class="docutils literal notranslate"><span class="pre">--rebase</span> <span class="pre">origin</span> <span class="pre">master</span></code> arguments to the <code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">pull</span></code> |
| command:</p> |
| <div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$ </span>git<span class="w"> </span>pull |
| </pre></div> |
| </div> |
| <p>Build and install the tool. The updated binary will be installed in the |
| <strong>$GOPATH/bin</strong> directory:</p> |
| <div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$ </span>go<span class="w"> </span>install |
| </pre></div> |
| </div> |
| <p>You can run the <code class="docutils literal notranslate"><span class="pre">ls</span> <span class="pre">-l</span></code> command to check the modification time for the |
| binary to ensure the new version is installed.</p> |
