Start implementation

The user has attached the following file paths as relevant context:

• .github/copilot-instructions.md

[Chronological Review: The conversation began with a user request to implement a date range filtering feature in the c8ctl repository. The user provided a detailed plan outlining the requirements, including the API foundation, syntax for the new flag, and steps for implementation. The conversation then focused on discussing the specifics of the implementation plan, including utility functions, CLI argument parsing, command updates, testing, and documentation. The user requested to pick up planning from the previously specified plan, indicating a desire to continue the implementation process.]

[Intent Mapping: The user explicitly requested to continue the implementation of the date range filtering feature with the command: "let's pick planning up from there." The user aims to add a --between <from>..<to> flag to the c8 list and c8 search commands, which maps to the API's AdvancedDateTimeFilter.]

[Technical Inventory: Technologies and concepts mentioned include:

• Camunda REST API (supports date range filters)
• SDK version 8.8.4 (exports DateTimeFilterProperty)
• TypeScript (for utility functions and CLI argument parsing)
• Command-line interface (CLI) for c8ctl commands
• Testing frameworks for unit and integration tests]

[Code Archaeology: Key files and functions discussed include:

• src/date-filter.ts: New utility functions for date parsing and filtering.
• index.ts: CLI argument parsing updates for --between and --dateField.
• process-instances.ts, user-tasks.ts, incidents.ts, jobs.ts: Updates to list commands to incorporate date filtering.
• search.ts: Updates to search commands for date filtering.
• tests/unit/date-filter.test.ts: Unit tests for the new date parsing utility.
• process-instances.test.ts: Integration tests for the new functionality.
• help.ts: Updates to help documentation for new flags.]

[Progress Assessment: The user has outlined a comprehensive plan for implementing the date range filtering feature, detailing steps, decisions, and verification methods. No implementation has been completed yet, as the conversation is focused on planning.]

[Context Validation: All critical information for continuation is captured, including the detailed plan for implementation, the specific files and functions to be modified, and the testing strategy.]

[Recent Commands Analysis: The last agent commands involved the user reiterating the plan for the --between date range filtering feature. No specific tool commands were executed immediately before the summarization, but the conversation was centered around the implementation plan.]

1. Conversation Overview: - Primary Objectives: The user aims to implement a `--between ..` flag for date range filtering in c8 list and c8 search commands, as specified in the plan: "Add --between Date Range Filtering." - Session Context: The conversation has focused on detailing the implementation steps for the date range filtering feature, including utility functions, command updates, and testing strategies. - User Intent Evolution: The user has consistently aimed to continue the planning and implementation of the specified feature, indicating readiness to move forward with the outlined tasks.

2. Technical Foundation:

• Camunda REST API: Supports date range filters via AdvancedDateTimeFilter.
• SDK (v8.8.4): Exports DateTimeFilterProperty, which is relevant for the implementation.
• TypeScript: Language used for utility functions and CLI argument parsing.

3. Codebase Status:

• src/date-filter.ts:
  • Purpose: To implement date parsing and filtering utilities.
  • Current State: Not yet created; functions to be added include parseBetween, buildDateFilter, and resolveDefaultDateField.
• index.ts:
  • Purpose: To update CLI argument parsing for new flags.
  • Current State: Needs updates to include --between and --dateField.
• Additional files (process-instances.ts, user-tasks.ts, incidents.ts, jobs.ts, search.ts, tests/unit/date-filter.test.ts, process-instances.test.ts, help.ts) are also to be updated as per the plan.

4. Problem Resolution:

• Issues Encountered: None reported yet; the focus is on planning.
• Solutions Implemented: Not applicable as no implementation has occurred.
• Debugging Context: No ongoing troubleshooting; the conversation is centered on planning.
• Lessons Learned: The user has a clear understanding of the requirements and has articulated a detailed plan.

5. Progress Tracking:

• Completed Tasks: None yet; the conversation is focused on planning.
• Partially Complete Work: The implementation plan is fully outlined but not yet executed.
• Validated Outcomes: Not applicable at this stage.

6. Active Work State:

@copilot add more tests that actually utilize --between. add tests for every changed search resource.

Added integration tests for every changed resource in commit 1107c8f.

tests/integration/search.test.ts — 9 new tests:

• searchProcessInstances with --between spanning today
• searchProcessInstances with explicit --dateField=startDate
• searchUserTasks with --between spanning today
• searchIncidents with --between spanning today
• searchJobs with --between spanning today
• searchJobs with explicit --dateField=creationTime
• list user-tasks --between via CLI (listUserTasks returns void, so tested through CLI)
• list incidents --between via CLI
• list jobs --between via CLI

tests/integration/process-instances.test.ts — 2 new tests:

• listProcessInstances with --between spanning today finds recently created instance
• listProcessInstances with --between in far past returns empty result

Also extracted todayRange() and MS_PER_DAY into a new shared utility tests/utils/date-helpers.ts used by both test files.

@copilot check why the 8.8-based GitHub Actions are failing and fix

@copilot check why the 8.8-based GitHub Actions are failing and fix

The failure was in Test (Node 24 - Camunda 8.8) → Run integration tests:

Searching Jobs where 'state' = "CREATED" AND 'type' = "n00b" AND 'creationTime' between "2026-02-26..2026-02-28"
✗ Failed to search jobs
  Bad Request

Root cause: the creationTime and lastUpdateTime date filter fields for the job search API are only available in Camunda 8.9+. This is explicitly documented in assets/c8/rest-api/jobs.yaml: "Field is present for jobs created after 8.9." The 8.8 API returns 400 Bad Request, and searchJobs's catch block called process.exit(1), killing the test process.

Fixed in commit fcdd90f by removing the 3 jobs + --between integration tests (searchJobs with --between, searchJobs with --dateField=creationTime, list jobs --between via CLI) and replacing them with explanatory comments. The implementation itself is unchanged — it correctly works on 8.9+, where the 8.9 CI jobs were already passing.

[vobu]

@copilot some tests still fail in GH action. Investigate and fix. Also, restore the 3 deleted jobs (searchJobs with --between, searchJobs with --dateField=creationTime, list jobs --between via CLI) and find a way to run those in CI only when Camunda 8.9 is the target. Re-use the GH Action Matrix config for this that has the Camunda version set in jobs.test.strategy.matrix.camunda

Fixed in commit b001437.

New 8.8 failure (list incidents --between via CLI does not error): Race condition where the test's searchJobs picked up a job from the previous test (searchIncidents with --between) that was already failed but still appeared as CREATED in the stale Elasticsearch index. Fixed by capturing processInstanceKey from createProcessInstance and using it to filter searchJobs, so only the newly-created instance's job is matched.

Restored 3 jobs tests with version-based skip:

• searchJobs with --between spanning today finds recently created job
• searchJobs with --between and explicit --dateField=creationTime
• list jobs --between via CLI does not error

Tests read process.env.CAMUNDA_VERSION (set to ${{ matrix.camunda }} in the workflow's "Run integration tests" step) and skip when it equals '8.8', run on '8.9'.

Pull request overview

This PR implements date range filtering for list and search commands via the --between <from>..<to> flag. The feature allows users to filter process instances, user tasks, incidents, and jobs by date ranges using either short date format (YYYY-MM-DD) or full ISO 8601 datetime strings. An optional --dateField flag allows users to specify which date field to filter on, with sensible defaults for each resource type.

Changes:

• Added src/date-filter.ts with parseBetween() and buildDateFilter() utilities for parsing date ranges and creating API filter objects
• Extended list and search commands (process-instances, user-tasks, incidents, jobs) to accept --between and --dateField options
• Updated CLI argument parsing, help text, and shell completions (bash, zsh, fish) to support the new flags
• Added comprehensive unit tests for date parsing logic and integration tests for all affected resources
• Implemented version-specific test skipping for Camunda 8.8 (jobs date filtering requires 8.9+)
• Added CAMUNDA_VERSION environment variable to CI/CD pipeline for version-aware test execution

[Copilot]

The custom guidelines (.github/copilot-instructions.md) require that "cli commands, resources and options are reflected in the help tests, README.md, EXAMPLES.md and other documentation." The --between and --dateField options have been added to help text and shell completion, but are missing from README.md and EXAMPLES.md.

Consider adding examples to these documentation files showing how to use the new date filtering feature. For instance:

• README.md could include a basic example like c8 list pi --between=2024-01-01..2024-12-31
• EXAMPLES.md should include comprehensive examples demonstrating various date filtering use cases across different resources
