Hello everyone,

I'm working on powershell, i'm working on modules as i'd like to have my code cleany wrote in modules.

So far i know how to list the available modules, and lucky me : my module is visible in that list that point to the "program files/windowPowerShell/Modules folder".
So my .psm1 file and my psd1 files are correct and in a folder having the same name.


So then i can import it with "Import-module -Name  <modulename>"

On "Get-Module -ListAvalaible" The column with ExportedCommands is empty for my module.
then i can not launch my cmdlets or functions, they dont exist in the session.
 

My Questions :
- how to check the problem i dont know what to do in order to have more infos  ?
- is the code ? is the module ? .....
   
 Get-Command -Module mymodule    <- gives me no output as if my module has no functions.

Thanks for your help.

What you get when you import the module?
Import-Module Test -Verbose

Open in new window

Did you see the command in ExportedCommands section when you use  Get-Module -ListAvailable

If not you can post the module which you are using so we can try to figure out the issue..

hello Subsun , first of every thing : A Happy New Year.

the verbose attribut wont give me more infos.

here's my module file:


Write-Host "Loading tshr package with utilities" -ForegroundColor Green
#Write-Host "from C:\Program Files\WindowsPowerShell\Modules\Tshr.GetDataOutOfFile" -ForegroundColor Green



function tshr-TestMethod() {
      return "Hello"
}



#function tshr-GetMachinesNames_OutOfDataFile_InArray( [string]$aFilePath="M:\PS_scripts\machinesTest.otl" )
#function tshr-GetMachinesNames-OutOfDataFile-InArray( [string]$aFilePath="M:\PS_scripts\machinesTest.otl" )
function tshr-GetMachinesNamesOutOfDataFileInArray( [string]$aFilePath="M:\PS_scripts\machinesTest.otl" )
{

<#
.SYNOPSYS
Will return all machines under test in an array
.EXAMPLE
first param can be a file with csv content. First column should be machine names
#>

      $linesWithData = Get-Content $aFilePath
      # ^ if no paramt received, will collect machines from default paramter.
      $machinesNames = @()  
      # ^ return an array of string

    foreach($aLine in $linesWithData){
        $machinesNames += $aLine.Split(";")[0].ToString().Trim();
    }
      return $machinesNames;
}



#function tshr-GetMachineAndTestUser_ForMachine( [string]$aFilePath="M:\PS_scripts\machinesTest.otl" )
#function tshr-GetMachineAndTestUser-ForMachine( [string]$aFilePath="M:\PS_scripts\machinesTest.otl" )
function tshr-GetMachineAndTestUserForMachine( [string]$aFilePath="M:\PS_scripts\machinesTest.otl" )
{

<#
.SYNOPSYS
will return objects with two members: machine name and test user for the machine
.EXAMPLE
we are going to display ....
#>

      $linesWithInfos = Get-Content $aFilePath
    # ^ if no paramt received, will collect machines from default paramter.
      $oMyCouples = @()
    # ^ return an array of string

      foreach($lineOneMachine in $linesWithInfos)
      {
            $hostname = $lineOneMachine.Split(";")[0].Trim();
            $username = $lineOneMachine.Split(";")[1].Trim();

            $oMyCouples +=
            @{
                  hostname="$hostname";
                  username="$username";
            }
      }
      return $oMyCouples;  
}



function tshr-testInclusionOfFile()
{
      Write-Host "ok, the file is in the sript"
}

Wish you too a very happy and prosperous new year.. :-)


This module looks ok.. My wild guess is that you missed to specify the module name in the manifest (in .psd1 file)
Sample .PSD1

Thanks a lot for your wild guess, you were right.

the thing is that when i just started playing with the module i could see the ExportedCommands column filled with the functions names......i did not pay attention when i lost them...

i didn't know the relation was necessary as they both are in the module folder. I 'll discover that soon ;)

thanks a lot again
