Suggested Batch Script Coding Conventions

• NOTE: These are just suggested conventions - having a consistent approach will help others find things - and makes locating sections for possible reuse, easier.

• Start a batch script with the following commands at the top:

  • @ECHO OFF
  • cls

• Immediatlely after, include a set of REM lines, to document the following:

  • Name of the script file
  • Semantic version information (i.e. Version x.y.x)
  • Author name
  • Author email
  • Author organization [optional]
  • Author URL (or organization URL) [optional]
  • Github URL to script location
  • Description

• When creating a name for a branch-to location in a script (i.e. for a goto destination) - use the following naming convention:

  • User UPPER CASE
  • Use "Snake Case" (e.g. YOU_NAME_IT_LIKE_THIS)
  • Prefix the name of the destation with JOB_, or STEP_

• For Example:

  • JOB_START
  • JOB_SETUP
  • STEP_[NAME]
    • For example:
      • STEP_VALIDATE_PARAMS
      • STEP_CHECK_DRIVE
      • STEP_CHECK_FILE
      • STEP_BEGIN_[PROCESS NAME]
  • JOB_ABORT
  • JOB_END
