Command Tool Development Using Description Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current command tools require labor-intensive hard-code development and updates, making them costly and tedious to maintain, especially when configuration changes or application APIs evolve.
Innovation Solution
A command description file is used to describe the function logic of commands, which can be parsed to execute operations, allowing developers and users to modify the command tool without extensive software development experience, reducing development costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If command tools are developed using hard-coded methods, then the tool can perform functions reliably, but the development and maintenance become labor-intensive and costly
Solution Approach 1:
The command tool is segmented into two parts: a persistent executable core and separate description files that contain the command definitions, parameters, and operation logic. This allows the tool to maintain reliability through the stable executable while enabling easy updates by simply modifying the description files without recompilation.
Solution Approach 2:
The command definitions, parameters, and operation logic are extracted from the hard-coded executable and placed into external description files. This extraction enables independent modification of command behaviors without affecting the core tool, reducing development and maintenance effort while preserving functionality.
2Adaptability or versatility
If command tools are updated to reflect configuration changes or API evolutions, then the tool remains relevant and functional, but the update process becomes tedious and requires extensive software development experience
Solution Approach 1:
Instead of modifying the core executable, the system uses description files that can be copied, created, or edited using simple text editors. Users can define new commands or modify existing ones by creating or editing these description files, making updates accessible to users without software development experience.
Solution Approach 2:
The command tool automatically parses and loads commands from description files without requiring manual intervention or recompilation. This self-service mechanism allows users to update command functionality by simply providing new description files, which the tool automatically incorporates.
3Stability of the object's composition
If the entire command tool is recompiled to modify functionality, then the tool maintains consistency, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The command definitions and logic are prepared in advance in description files with a structured format. This preliminary preparation allows the executable to simply parse and load the pre-defined commands without needing to recompile, maintaining tool consistency while eliminating recompilation time.

AI summary
Embodiments of the present disclosure relate to a computer-implemented method for executing one or more operations based on a command. According to the method, a command is received. A command name of the command and one or more parameters of the command are extracted. A command description file corresponding to the command is retrieved based on the command name. The command description file describes function logic of the command. The retrieved command description file is parsed, and information for executing one or more operations included in the command description file is acquired. The one or more operations are executed based on the acquired information and the one or more parameters.
