[WIP] Add text input navigation features for substreams init

[Copilot]

Cloud agent has begun work on implement this. and will update this pull request as work progresses.

Original prompt

implement this.

[Chronological Review: The conversation began with the user requesting a new feature for the `substreams init` command, specifically for text input navigation. The user outlined functionality for key navigation and text completion. The user then suggested updating the library "huh" to the latest version and using a FilePicker for file handling. Following this, the user requested verification of claims regarding the library's capabilities by inspecting its public API. The user also requested a file rename from `input_history.go` to `init_input_history.go` and finally asked for implementation of the discussed features.]

[Intent Mapping:

1. "Ok would like plan a new feature when using substreams init..." - User requests specific text input navigation features.
2. "Seems like the plan could: Update huh to latest..." - User suggests updating a library and using FilePicker.
3. "Verify your claims about Huh having support..." - User asks for verification of library capabilities.
4. "./cmd/substreams/input_history.go => ./cmd/substreams/init_input_history.go" - User requests a file rename.
5. "implement this." - User requests implementation of the discussed features.]

[Technical Inventory:

• Library: "huh" (version 0.8.0) - used for text input handling.
• FilePicker - suggested for file handling and completion.
• File structure: ./cmd/substreams/input_history.go to be renamed to ./cmd/substreams/init_input_history.go.]

[Code Archaeology:

• File: input_history.go - to be renamed to init_input_history.go as per user request.
• Functions related to text input navigation and history management were discussed but not yet detailed.]

[Progress Assessment:

• Completed Tasks: User has outlined features for text input navigation.
• Partially Complete Work: Verification of library capabilities is pending, and the implementation of the new features has been requested but not yet executed.]

[Context Validation: All necessary context for continuing work on text input navigation features and library verification is captured.]

[Recent Commands Analysis:

• Last Agent Commands: User requested to implement the new features and rename a file.
• Tool Results Summary: No specific tool results were returned as the commands were user requests.
• Pre-Summary State: The agent was preparing to implement the requested features and rename the file when the token budget was exceeded.
• Operation Context: The commands were executed to align with the user's goals of enhancing text input navigation and ensuring the correct file structure.]

1. Conversation Overview: - Primary Objectives: User requested features for text input navigation in `substreams init`, including key navigation and text completion. User also suggested updating the "huh" library and using FilePicker for file handling. - Session Context: The conversation flowed from feature requests to library verification and file renaming, culminating in a request for implementation. - User Intent Evolution: The user initially focused on feature requests, then shifted to library updates and verification, and finally requested implementation.

2. Technical Foundation:

• Library: "huh" (version 0.8.0) - used for text input handling.
• FilePicker: Suggested for handling file inputs and automatic completion.

3. Codebase Status:

• File Name: input_history.go
  • Purpose: Manages input history for the substreams command.
  • Current State: User requested to rename it to init_input_history.go.
  • Key Code Segments: Functions related to input history management were discussed but not detailed.
  • Dependencies: Related to the overall input handling functionality.

4. Problem Resolution:

• Issues Encountered: No specific technical problems were reported, but verification of library capabilities is pending.
• Solutions Implemented: User has outlined features but implementation is yet to be executed.
• Debugging Context: No ongoing troubleshooting efforts were mentioned.
• Lessons Learned: User is focused on enhancing user experience through improved input navigation.

5. Progress Tracking:

• Completed Tasks: Feature outlines for text input navigation.
• Partially Complete Work: Verification of library capabilities and implementation of features are pending.
• Validated Outcomes: None confirmed yet as implementation has not started.

6. Active Work State:

• Current Focus: User is focused on implementing text input navigation features and renaming the file.
• Recent Context: User requested to implement the discussed features and rename the file.
• Working Code: No specific code snippets were provided for modification.
• Immediate Context: User requested implementation of the outlined features.

7. Recent Operations:

• Last Agent Commands: User requested to implement features and rename a file.
• Tool Results Summary: No specific tool results were returned as these were user requests.
• Pre-Summary State: The agent was ...
