    osx-env-sync

Synchronize OS X environment variables for command line and GUI applications from a single source
Introduction

On OS X, command line applications and GUI applications are treated differently. (Well this can be put in a more technically correct manner but this is what you experience from a user's point of view.) One fundamental difference is that although it's straightforward to feed command line applications with environment variables, it's not so for GUI applications. It's even harder to feed both types of applications from a single source of definitions. (Well, one particular workaround is launching GUI applications from command line.) Moreover, OS X's relevant means for setting up environment variables (or initializing programs in general) have been changing over time in consecutive releases which makes the situation worse. Hundreds of topics at Stack Overflow is the living proof of this mess.
osx-env-sync provides a simple and effective solution for synchronizing environment variables for both command line and GUI applications from a single source. Unlike many other solutions/workarounds provided at Stack Overflow and many blogs, osx-env-sync is simple and works with the latest version of OS X. (Tested on version 10.10.5.)
Usage

Make sure your ~/.bash_profile has the necessary export statements. You can have more than one export statement for a variable and you can use variable substitution as well, in the same way you define environment variables as usual. Here is an example:
export JAVA_HOME="$(/usr/libexec/java_home -v 1.8)"
export GOPATH="$HOME/go"
export PATH="$PATH:/usr/local/opt/go/libexec/bin:$GOPATH/bin"
export PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
export MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"
export PATH="$PATH:$HOME/bin"

Open your terminal and follow the steps below.
Download the launch agent:
curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync.plist -o ~/Library/LaunchAgents/osx-env-sync.plist
Download the shell script:
curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync.sh -o ~/.osx-env-sync.sh
Make sure the shell script is executable:
chmod +x ~/.osx-env-sync.sh
Load the launch agent for current session:
launchctl load ~/Library/LaunchAgents/osx-env-sync.plist
(Re)Launch a GUI application and verify that it can read the environment variables.
The setup is persistent. It will survive restarts and relogins.
After the initial setup (that you just did), if you want to reflect any changes in your ~/.bash_profile to your whole environment again, rerunning the launchctl load ... command won't perform what you want; instead you'll get a warning like the following:
<$HOME>/Library/LaunchAgents/osx-env-sync.plist: Operation already in progress
In order to reload your environment variables without going through the logout/login process, do the following:
launchctl unload ~/Library/LaunchAgents/osx-env-sync.plist
launchctl load ~/Library/LaunchAgents/osx-env-sync.plist
If you want to automate this two step process with a script, download and make it executable (assuming you have a ~/bin directory and its on your $PATH as in the example above):
curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync-now -o ~/bin/osx-env-sync-now
chmod +x ~/bin/osx-env-sync-now
And run the script whenever you want to reload your environment variables:
osx-env-sync-now
Finally make sure that you relaunch your already running applications (including Terminal.app) to make them aware of the changes.
Details

On OS X, each Terminal.app session (window or tab) is accompanied with your configured login shell, /bin/bash by default. During login shell startup, the following files are sourced in order:

/etc/profile
/etc/bashrc
~/.bash_profile

These files are sourced upon user login as well. But before these files, there is another type of script (well, there are others too) executed on behalf of the user: Launch Agents. osx-env-sync provides a launch agent which initializes a login shell -achieved by passing -l parameter to bash- so that ~/.bash_profile is sourced in the first place and uses launchctl command to set environment variables for the whole user session. A shell script helps the launch agent by parsing ~/.bash_profile just for reading the names of the environment variables; values of the variables are already effective in the launch agent execution environment as the shell script is run with a login shell by the agent.
More Details

While /etc/profile is being sourced, /usr/libexec/path_helper program is executed to set initial values of PATH and MANPATH environment variables. The program processes /etc/paths file as well as /etc/paths.d/ and /etc/manpaths.d/ directories for bootstrapping the variables. You can also edit contents of these files and directories for system wide effect.

          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution

      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the

      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
