Abstract

A method and system for validating a Command Line Interface (CLI) configlet on an image is provided. The method includes creating a parse graph using a plurality of self-describing data constructs, identifying a plurality of parse chain data constructs in the parse graph, deriving at least one CLI/configlet from the image file based on the plurality of self-describing data constructs; and comparing the at least one CLI/configlet derived from the image file with a plurality of CLIs/configlets.

Claims

1. A method for validating a Command Line Interface(CLI)/configlet on an image, the method comprising:

creating a parse graph using a plurality of self-describing data constructs;

identifying a plurality of parse chain data constructs in the parse graph;

deriving at least one CLI/configlet from the image file based on the plurality of self-describing data constructs; and

comparing the at least one CLI/configlet derived from the image file with a plurality of CLIs/configlets.

2. The method according to claim 1, wherein the image file is an Executable and Linking Format image.

3. The method according to claim 1, wherein the plurality of self-describing data constructs created for the image file comprises a plurality of link points.

4. The method according to claim 1, wherein the plurality of self-describing data constructs created for the image file comprises a plurality of link exits.

5. The method according to claim 1, wherein the plurality of self-describing data constructs created for the image file comprises a plurality of parser modes.

6. The method according to claim 1, wherein the plurality of self-describing data constructs created for the image file comprises a plurality of commands.

7. The method of claim 1 wherein said validating a CLI/configlet on an image is without running the image on a device.

8. A system for validating a Command Line Interface(CLI)/configlet on an image, the system comprising:

means for creating a parse graph using a plurality of self-describing data constructs;

means for identifying a plurality of parse chain data constructs in the parse graph;

means for deriving at least one CLI/configlet from the image file based on the plurality of self-describing data constructs; and

means for comparing the at least one CLI/configlet derived from the image file with a plurality of CLIs/configlets.

9. A system for validating a Command Line Interface (CLI)/configlet on an image, the system comprising:

a data construct creator for creating a plurality of self-describing data constructs for the image file;

a graph creator for creating a parse graph using the plurality of self-describing data constructs;

a construct identifier for identifying a plurality of parse chain data constructs in the parse graph;

a CLI extractor for deriving at least one CLI/configlet from the image file based on the plurality of parse chain data constructs; and

a comparing unit for comparing the at least one CLI/configlet derived from the image file with a plurality of CLIs/configlets.

10. The system according to claim 9, wherein the image is an Executable and Linking Format image.

11. The system according to claim 9, wherein the self-describing data constructs created from the image file comprise a plurality of link points.

12. The system according to claim 9, wherein the self-describing data constructs created from the image file comprise a plurality of link exits.

13. The system according to claim 9, wherein the self-describing data constructs created from the image file comprise a plurality of parser modes.

14. The system according to claim 9, wherein the self-describing data constructs created from the image file comprise a plurality of commands.

15. A machine-readable medium including instructions executable by the processor for validating a Command Line Interface (CLI)/configlet on an image, the machine-readable medium comprising:

program instruction means for creating a parse graph using a plurality of self-describing data constructs;

program instruction means for identifying a plurality of parse chain data constructs in the parse graph;

program instruction means for deriving at least one CLI/configlet from the image file based on the plurality of self-describing data constructs; and

program instruction means for comparing the at least one CLI/configlet derived from the image file with a plurality of CLIs/configlets.
