Compare-NAVApplicationObject

Compares text files with Business Central application objects and then calculates the delta between the two versions. The result of the comparison is a number of text files with the calculated delta. The deltas can later be applied to a third version by using the Update-NAVApplicationObject cmdlet.

Description

Use the Compare-NAVApplicationObject cmdlet to calculate the delta between one version of Business Central application objects and another version. The deltas can later be applied to a third version by using the Update-NAVApplicationObject cmdlet.

The Compare-NAVApplicationObject cmdlet compares the text files in the two specified folders and creates .delta files that describe the difference between the two versions. The text files must contain Business Central application objects that have been exported from the Business Central Development Environment. You can compare two text files that contain multiple application objects, and you can compare text files in two folders where each text file can contain one or more application objects.

The cmdlet creates a text file for each application object that is different between the two versions. For example, you compare two versions of table 27: an original version and a modified version. The modified version has added a field to the table compared to the original version. In this example, the Compare-NAVApplicationObject cmdlet creates a delta file,TAB27.delta, that describes the difference that the extra field must be inserted into the table. Then, you use the Update-NAVApplicationObject cmdlet to apply the delta to target files.

Examples

EXAMPLE 1

Compare-NAVApplicationObject -OriginalPath .\demodata\ORIGINAL\*.txt -ModifiedPath .\demodata\MODIFIED\*.txt -DeltaPath .\demodata\DELTA\

          Processed 14 objects:
          Inserted   0 objects
          Deleted    1 objects
          Changed    4 objects
          Identical  9 objects
          Failed     0 objects

This example compares the text files in the MODIFIED folder to the baseline in the ORIGINAL folder. The result of the comparison is put into the DELTA folder. When the comparison completes, a summary is shown.

EXAMPLE 2

Compare-NAVApplicationObject -OriginalPath .\demodata\ORIGINAL\*.txt -ModifiedPath .\demodata\MODIFIED\*.txt -DeltaPath .\demodata\DELTA -Force -PassThru |
          Update-NAVApplicationObject -TargetPath .\demodata\TARGET\*.txt -ResultPath .\demodata\RESULT -Force

          Processed 14 objects:
          Inserted   0 objects
          Deleted    1 objects
          Updated    3 objects
          Identical  9 objects
          Conflict   1 objects
          Failed     0 objects

This example compares the text files in the MODIFIED folder to the baseline in the ORIGINAL folder. The result of the comparison is put into the DELTA folder and also piped to the Update-NAVApplicationObject cmdlet, which applies the updates. When the comparison completes, a summary is shown.

Parameters

-Confirm

Specifies that the user must confirm the process before the cmdlet runs.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-DeltaPath

Specifies the folder where the result of the comparison between the two versions of application objects must be put. For example, to place the result of the comparison in the DELTA folder that is a subfolder to the current folder, type .\DELTA*.txt.

Type:String
Aliases:Delta
Position:3
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ExportToNewSyntax

Export the application objects to the syntax supported by the Txt2Al converter.

Type:SwitchParameter
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-Force

Forces the cmdlet to overwrite any existing files in the Delta folder.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-IgnoreDocumentation

Specifies not to include the content of the documentation triggers in the objects as part of the comparison.

Type:SwitchParameter
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-Legacy

Reduces the scope of the cmdlet. Do not set this parameter.

Type:SwitchParameter
Aliases:DevBaseCompatibility
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ModifiedPath

Specifies the application objects that you want to compare to the original version.

For example, to compare all text files in the MODIFIED folder that is a subfolder to the current folder, type .\MODIFIED*.txt.

Type:String[]
Aliases:Modified
Position:2
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-NoCodeCompression

Specifies if the files that are the result of the comparison must not be compressed.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-OriginalPath

Specifies the application objects that are the baseline of the file comparison.

For example, to use all text files in the ORIGINAL folder that is a subfolder to the current folder, type .\ORIGINAL*.txt.

Type:String[]
Aliases:Original
Position:1
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Specifies if the cmdlet must return a FileInfo object for each .delta file that is created by the comparison. If you do not set this parameter, the cmdlet returns a list of the files.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Outputs

None or an object representing the .DELTA file that was created.

When you set the PassThru parameter, the Compare-NavApplicationObject cmdlet returns a FileInfo object for each created .DELTA file. Otherwise, this cmdlet does not generate any output.
