PSEC - Powershell Enhanced Capability
Version 1.2.1

PSEC - Powershell Enhanced Capability

A set of additional functions for Powershell that includes a robust GUI API and a comprehensive Workflow facility

The PSEC package provides a set of routines that enhance PowerShell. They include:

  1. Addition commands to supplement Powershell. See CMDS - Overview

  2. A robust GUI system. See PSEC - GUI Capability

  3. A comprehensive Workflow package based on the builtin GUI. See PSEC - Workflow Facility Overview

  4. Restart facilities to aid in developing scripts and classes. See PSEC - Restart Facility

  5. Themed icon and console management for multiple simultaneous PSEC applications. See PSEC - Icon and Console Management.

  6. A built-in documentation system that builds what you are reading. See PSEC - Rebuilding Documentation

  7. Working examples to use as a basis for custom Workflows or further development. See PSEC - Reference Examples

PSEC Installer Download

A current version of PSEC installation can be obtained at the following location. The .exe is a self-extracting zip file that will guide you through the install process.

The zip file contains the Powershell source files, working examples and this documentation.

Note: The file is downloaded as a .bin file to avoid download complications in the browser. It should be renamed once downloaded by dropping the .bin suffix. If you have a virus scanner installed the rename process will trigger a local scan of the file.

The download can be obtained at: DOWNLOAD PSEC Installer EXE

Hello World Example

The ease of creating a Workflow in PSEC is shown by the following example.

It orchestrates the creation of a file that takes a long time followed by the processing of the file once it is created.

The command flow psec-hello in a PSEC window starts the orchestration.

The detailed explanation can be seen at PSEC Hello World Example.

See Sample NAME-cfg.json Format for the parameter description of this file.

Step 1 Create File Script

Running Step 1 creates a file after a configured delay.

The file name is calculated from the task location and the configured name. It is passed to the subsequent steps in a global hashmap provided by the PSEC Workflow infrastructure.


$targFile = "$($task.execLocn)/$($cfgParms['file'])"
$sleepSecs = $cfgParms['sleep']
$task.tfs.globMap.creFile = $targFile;

$msg = "creating $targFile after $sleepSecs secs"
Remove-Item -Path $targFile -force

Start-Job -ScriptBlock {
  start-sleep $using:sleepSecs
  Set-Content -Path $using:targFile -Value $using:msg
  $wshell = New-Object -ComObject Wscript.Shell
  $Output = $wshell.Popup($using:msg)

$brief.createMsg = $msg
Step 2 Wait File Script

Running Step 2 generates a FAIL or GOOD status depending on whether the file creation has completed.


$targFile = $task.tfs.globMap.creFile;
if (test-path $targFile) {
  $brief.sCondCode = "GOOD"
  $brief.waitMsg = "$targFile found"
} else {
  $brief.sCondCode = "FAIL"
  $brief.waitMsg = "$targFile not yet located"
"wait-data-run.ps1 finished`r`n";
Step 3 Process File Script

Step 3, the file processing step, is prevented from running until Step 2 has succeeded.


$targFile = $task.tfs.globMap.creFile;
$brief.procMsg = "$targFile ready for processing"
"process-data-run.ps1 finished`r`n";
Workflow Interface After Create File Initiated

Note that the top left shows the state of the 3 Steps and the main panel has more information concerning the state of the current task.

Workflow Interface After Wait File Succeeds, Process File not yet run

Planned Enhancements

A GUI configurator engine to build the Workflows. See PSEC - Workflow Configurator.
