Environment Variables
Introduction
Environment variables are a fundamental part of developing application. eWam 7 tries as much as possible to follow the 12 factors methodology. One aspect of this is to leverage environment variables.
Default ewam env variables
eWAM accepts a certain number of environment variables to allow you to customize your development and run-time environment.
| Environment Variables | Description | Default |
|---|---|---|
WYDE-ROOT | This variable is the main environment variable, pointing to the directory in which ewam-kernel have been installed. Other environment variables that are not explicitly specified will be defined relative to this variable. | ./node_modules /@ewam/kernel |
WYDE-DLL | Directory from which application DLLs are loaded. These application DLLs include DLLs you build with the C++ producer, as well as WAM system DLLs for various tools and options of WAM. (Note that starting for version 7.0.4, this environment variable support multiple folder (like PATH)) | ./node_modules/@ewam/library/CPPDLL |
WYDE-ADMIN | The directory in which eWam and other Wyde solutions (wInterface, wPortal, ...) store accesses to external systems. | ./ADMIN |
WYDE-HELP | Directory in which WAM's on-line help is installed. Note that, for this environment variable, you can put URL's in case the help is installed on a Web Server to which you have access. For example, WYDE-HELP=https://mphasiswyde.github.io/ewam-docs/ | ./node_modules/@ewam/help |
WYDE-LICENSE | The directory in which ewam license file (eWAM6100.lcs) is located. It is recommended that you set it globally on your computer. | WYDE-ROOT |
WYDE-SERVERLICENSE | The directory in which server licenses files (wydeweb.lcs, wed.lcs, ewed.lcs) are located (WydeWeb, Wed, eWed). See Licenses for more information. | WYDE-ROOT |
WYDE-DEVTGV | The directory in which the development TGV data base W003001.TGV is located. | ./TGV |
WYDE-ERR | Directory in which logs are located. | ./LOG |
WYDE-IMPEXP | Directory from which import/export files are loaded and to which they are stored if full path name isn't supplied to the Import/Export Tool. | ./IMPEXP |
WYDE-REFDEVTGV | Directory in which the shared repository TGV data base W004001.TGV is located. This variable must be set to the correct directory for workgroup functionality to work. | ./TGV |
WYDE-SYSTGV | The directory in which the system TGV data base W001001.TGV is located. | ./TGV |
WYDE-TESTTGV | The directory in which the development TGV data base (by default W007001.TGV) is located. | ./TGV |
WYDE-TGV | The root directory for TGV data bases. Unless otherwise specified, WYDE-DEVTGV, WYDE_IMPEXP, WYDE-REFDEVTGV, WYDE-SYSTGV, and WYDE-TESTTGV point to his same directory. | ./TGV |
WYDE-TUTORIAL | Directory in which WAM's on-line tutorials are installed. Note that, for this environment variable, you can put URL's in case the tutorials are installed on a Web Server to which you have access. | ./node_modules/@ewam/help |
WYDE-CPPFILES | Default output for cpp generated files | ./.build/cpp |
WYDE-COMPILERESULTS | Default output for cpp generated dlls | ./.build/cppdll |
Using .Env
Before we get into the specifics, you should read the excellent post from John Papa
Change the Admin location
- Open boilerplate/developer/.env
- Change
WYDE-ADMIN=../AdmintoWYDE-ADMIN=./Admin2 - Open eWam
- Check the variable is changed
