The tempViper.MergeInConfig() call was attempting to merge the config into itself,
which was causing YAML template functions to return null values on Windows.

This bug was introduced in PR #1447 and caused test failures in:
- TestYamlFuncTerraformOutput
- TestProcessCustomYamlTags

The fix removes this unnecessary call since we're already processing the config
correctly by marshaling tempViper to YAML and then merging it into the main
Viper instance.

* fix: restore config import override behavior while maintaining Windows fix

- Re-merge original config content after processing imports to ensure main config takes precedence
- This fixes TestInitCliConfig/valid_import_custom_override while keeping Windows tests passing
- Imports now correctly serve as base configuration that can be overridden by the main config

The fix ensures proper config precedence: imports are processed first as a base layer,
then the main config is applied on top as an override layer.

- Modified processConfigImportsAndReapply to ensure commands from

- Added comprehensive tests for command merging from .atmos.d
- Fixed existing test that was checking for incorrect error message

…ility (#1504)

* fix: handle triple-slash vendor URIs after go-getter v1.7.9 update

The go-getter update from v1.7.8 to v1.7.9 (introduced in Atmos v1.189.0)
broke the documented triple-slash pattern (///) for vendoring from Git
repository roots. This pattern was widely used and documented in Atmos
examples.

Changes:
- Add normalizeVendorURI() to convert /// patterns to go-getter v1.7.9 format
- Convert "repo.git///?ref=v1.0" to "repo.git?ref=v1.0" (empty subdir)
- Convert "repo.git///path?ref=v1.0" to "repo.git//path?ref=v1.0" (with subdir)
- Add comprehensive test cases for the vendor pull issue

Root Cause:
go-getter v1.7.9 included security fixes for CVE-2025-8959 that changed
subdirectory path handling, making the triple-slash pattern no longer
functional for downloading Git repository contents.

🤖 Generated with [Claude Code](https://claude.ai/code)

* refactor: rename vendor triple-slash test files to be more descriptive

- Renamed test file from vendor_issue_dev3639_test.go to vendor_triple_slash_test.go
- Renamed test scenario directory from vendor-pull-issue-dev-3639 to vendor-triple-slash
- Updated test function name and comments to describe what is being tested (triple-slash pattern)
- Test files should be named based on what they test, not issue numbers

* docs: improve triple-slash pattern documentation

- Clarified that // is a delimiter and / after it represents the subdirectory path
- Explained that /// means empty subdirectory (root of repository)
- Added reference to CVE-2025-8959 which caused the breaking change in go-getter v1.7.9
- Updated inline comments to be more precise about the pattern's meaning

* test: add unit tests for normalizeVendorURI and fix missing test function

- Added comprehensive unit tests for normalizeVendorURI function
- Fixed normalizeVendorURI to be more precise about .git/// patterns
- Preserved file:/// URIs unchanged (valid file scheme)
- Added missing verifyFileExists function in terraform_clean_test.go
- Addressed linter issues (nestif complexity, magic numbers)

* docs: clarify triple-slash pattern as root of repository

Updated documentation to describe the triple-slash pattern (///) as indicating
the root of the repository rather than an "empty subdirectory", which is more
accurate and intuitive for understanding the go-getter URL syntax.

🤖 Generated with [Claude Code](https://claude.ai/code)

Co-Authored-By: Claude <noreply@anthropic.com>

* fix: normalize vendor URIs to handle triple-slash pattern correctly

- Created unified normalizeVendorURI function to handle all URI normalization in one place
- Converts triple-slash (///) to double-slash-dot (//.) for repository root
- Adds //. to Git URLs without subdirectory delimiter
- Extracted URI pattern detection logic into separate helper functions for better maintainability
- Deprecated adjustSubdir in CustomGitDetector as normalization now happens earlier in pipeline

* fix: merge commands from all sources preserving precedence hierarchy (#1533)

* fix: merge commands from .atmos.d instead of replacing them

Fixed a regression where commands defined in .atmos.d/ directories were
being replaced instead of merged with main configuration commands. This
prevented custom commands like 'atmos dev' from working properly.

The issue was introduced in PRs #1447 and #1489 which formalized the
override behavior for configuration imports. While this behavior is
correct for most configuration fields, command arrays should be merged
to allow extending the CLI with custom commands.

Changes:
- Added mergeCommandArrays function to properly merge command arrays
  with deduplication based on command names
- Updated mergeConfigFile to preserve and merge command arrays when
  processing imports
- Modified processConfigImportsAndReapply to ensure commands from
  .atmos.d and other imports are preserved when re-applying main config
- Added comprehensive tests for command merging from .atmos.d
- Fixed existing test that was checking for incorrect error message

This fix ensures that:
- Commands from .atmos.d directories are properly merged with main
  configuration commands
- Multiple command sources can coexist without replacing each other
- The 'atmos dev' command and its subcommands work as expected

Fixes the regression where 'atmos dev --help' was not working.

* test: add comprehensive test coverage for command import merging

- Add command_merging_behavior_test.go with detailed merge scenarios
- Add import_commands_test.go for various import configurations
- Add final_test.go with real-world validation tests
- Update imports.go with debug logging for import processing
- Fix load.go command merging to properly handle import precedence

These tests validate:
- Commands from imports merge with local commands
- Local commands override imported commands with duplicate names
- Deep nested imports (4+ levels) work correctly
- CloudPosse use case: 10 upstream + 1 local = 11 total commands

* refactor: rename final_test.go to command_merge_core_test.go

- Rename test file to better describe its purpose
- Update function name from TestFinalCommandMergingBehavior to TestCommandMergeCore
- This test validates core command merging functionality

* docs: add comprehensive PRD for command merging functionality

- Added Product Requirements Document detailing command merging implementation
- Included PR description with technical details and test coverage information
- Documents fix for regression where imported commands were replaced instead of merged
- Captures CloudPosse's use case and multi-level import requirements

* chore: remove PR description file from repository

* test: fix failing test expectations after command merge order changes

- Update test expectations to match actual command ordering behavior
- Commands now appear in order: main, defaults (.atmos.d), imports
- This allows main commands to override imported commands by name
- Fix test YAML to use string steps instead of complex step objects
- Update error message expectation in processConfigImportsAndReapply test

* test: update golden snapshots for command merging functionality

The test 'atmos_describe_config_imports' was failing because it now correctly
merges commands from imported configurations (including remote imports from
GitHub) instead of replacing them. Updated the golden snapshots to reflect
the expected output with merged commands (tf, terraform, show, and test).

This fixes test failures on Linux, macOS, and Windows CI pipelines.

* test: fix failing test expectations after command merge order changes

- Fixed all inline comments in command_merging_behavior_test.go to end with periods
  as required by golangci-lint's godot linter
- Replaced fragment-only markdown links with full GitHub URLs in command-merging.md
  to satisfy markdownlint MD051 (fixes #1447 and #1489 links)
- Added 'text' language hint to fenced code block in command-merging.md to satisfy
  markdownlint MD040

These changes address all linting warnings and ensure consistent code style.

* refactor: simplify template processing to use file extension detection

Replace process_without_context configuration flag with automatic template detection based on file extension.
Files with .yaml.tmpl or .yml.tmpl extensions are now always processed as Go templates, regardless of whether
context is provided. This simplifies the mental model and reduces configuration surface area.

Changes:
- Remove ProcessWithoutContext flag and TemplateSettingsImport struct from schema
- Add IsTemplateFile() utility to detect template files by extension
- Update template processing logic to use file extension instead of config flag
- Add comprehensive unit tests for template processing without context
- Update documentation to clarify new behavior

This makes the behavior more intuitive: .tmpl files are templates, non-.tmpl files are not.
Users can still use skip_templates_processing flag for explicit control when needed.

* fix: resolve golangci-lint commentedOutCode warnings

Remove assignment operator from inline comments to fix linter warnings.
Changed comments from 'skipTemplatesProcessingInImports = true/false'
to just 'skipTemplatesProcessingInImports' to avoid triggering the
commentedOutCode linter rule.

* chore: remove vendor diff functionality

Remove vendor diff command and related functionality that was
pulled in from the devel branch. This PR is focused solely on
import context functionality.

- Remove cmd/vendor_diff.go command file
- Revert vendor.go, vendor_model.go, vendor_utils.go to main branch versions
- Update vendor_test.go to remove vendorDiffCmd test
- Refactor stack_processor_utils.go to fix linting complexity issue

* fix: handle all .tmpl files in template processing

Fix test failures by properly detecting and processing all template files.
The previous change only processed .yaml.tmpl and .yml.tmpl files, but
missed plain .tmpl files which are used in test fixtures.

Now processes templates when:
1. File has .yaml.tmpl or .yml.tmpl extension (always)
2. OR file has .tmpl extension AND context is provided

This maintains backward compatibility while fixing test failures across
all platforms (Windows, Linux, macOS).

* fix: restore vendor diff stub from main branch

The vendor diff command exists in main as an unimplemented stub.
We had incorrectly deleted it entirely when removing the devel
implementation. This restores the stub version that returns
'not implemented yet' error, maintaining compatibility with main.

* fix: restore original template processing behavior with testable logic

This commit fixes template processing to match the documented behavior
where ANY file with context is processed as a template. The previous
change incorrectly restricted template processing to specific file
extensions only.

Key changes:
- Added ShouldProcessFileAsTemplate function for testable decision logic
- Restored behavior: process any file as template when context provided
- Always process .yaml.tmpl, .yml.tmpl, and .tmpl files
- Added comprehensive unit tests for all scenarios
- Created PRD documenting template processing requirements

This fixes test failures where template syntax was leaking into output
(e.g., tenant1-{{ .environment }}-test-1) because plain YAML files with
context were not being processed as templates.

* fix: restore correct golden snapshots for git repo test

The golden snapshots were incorrectly regenerated to show error output
when they should show the successful list of stacks. This test verifies
that Atmos doesn't warn about missing git repo when it has a valid
config, and should successfully list the stacks.

Restored golden files from main branch which contain the correct
expected output.

* fix: restore circuit breaker functionality with proper PATH inheritance

- Fix PATH environment variable inheritance for nested atmos subprocess calls
- Add testable utility functions for PATH management in pkg/utils/env_utils.go
- Prevent test case environment from overriding AtmosRunner's carefully constructed PATH
- Remove problematic "which atmos" test that relied on system PATH lookup
- Ensure circuit breaker properly detects infinite recursion in workflow commands
- Clean up debugging output to restore clean test execution

- ShouldProcessFileAsTemplate function in stack_processor_utils.go
- formatTemplateProcessingError function in stack_processor_utils.go

* chore: remove .go-version file

The Go version is already specified in go.mod and doesn't need
a separate version manager file.

* fix: resolve Windows test failure with environment variable isolation

Fixed the failing test "!terraform.output from component with !env function test"
on Windows by improving test environment isolation and adding missing environment variable.

Changes:
- Add t.Setenv() loop in cli_test.go to set all test environment variables with proper isolation
- Add missing ATMOS_TEST_1 environment variable to the terraform.output test case
- Convert os.Setenv() calls to t.Setenv() in test files for automatic cleanup
- Fix XDG_CACHE_HOME setting to use t.Setenv() instead of os.Setenv()
- Simplify sandbox test environment setup using t.Setenv()

The issue was caused by improved test isolation in PR #1524 which prevented tests
from inheriting environment variables from the parent process. The test was
previously working because it accidentally inherited ATMOS_TEST_1 from the CI
environment, but now requires explicit configuration.

This fix ensures:
- component-5 can resolve !env ATMOS_TEST_1 to "test-env-and-terraform-output-functions"
- component-6 can get that value via !terraform.output component-5 foo
- Test passes consistently across all platforms with proper isolation

- Enhanced sanitizeImport to handle all URL schemes (git::, s3::, gcs::, oci::, hg::, etc.)
- Added comprehensive test coverage for sanitizeImport with 16 test cases
- Restored verifyFileExists and verifyFileDeleted test helper functions
- Converted os.Setenv to t.Setenv in vendor_triple_slash_test.go

## why
- sanitizeImport only sanitized HTTP/HTTPS URLs, missing credentials in other schemes like git::https://, s3::, oci::
- go-getter supports many schemes that can contain credentials and need sanitization
- verifyFileExists and verifyFileDeleted helpers were incorrectly removed in commit 32065af, reducing testability and reusability

* fix: add case-insensitive path matching for Windows CI snapshots

## what
- Fixed sanitizeOutput to use case-insensitive regex matching for repo paths
- Added explicit backslash-to-forward-slash normalization for Windows paths
- Created comprehensive test suite (cli_sanitize_test.go) with 50+ test cases
- Added nolint directive for acceptable complexity in template error handling

## why
- Windows CI was failing on TestCLICommands/atmos_describe_config_imports
- Issue: repo root D:\a\atmos\atmos didn't match output d:/a/atmos/atmos
- Root causes:
  1. Case sensitivity in path matching (D: vs d:)
  2. Backslashes in Windows paths not being normalized
- Golden snapshots expect normalized paths like /absolute/path/to/repo

## tests
- TestSanitizeOutput_WindowsCIFailureScenario: Reproduces exact CI failure
  - Tests D:\a\atmos\atmos (backslashes, uppercase)
  - Tests d:\a\atmos\atmos (backslashes, lowercase)
  - Tests d:/a/atmos/atmos (forward slashes, lowercase)
  - Tests mixed case in path segments
- TestSanitizeOutput: Core functionality (URLs, debug logs, tokens)
- TestCollapseExtraSlashes: Protocol and slash normalization

* fix: only replace backslashes on Windows in sanitizeOutput

## what
- Restrict backslash-to-forward-slash conversion to Windows only in sanitizeOutput
- Preserve backslashes on Unix/macOS where they are legitimate characters (escape sequences)

## why
- Previous fix for Windows broke macOS and Linux CI tests
- The unconditional `strings.ReplaceAll(output, "\\", "/")` was corrupting legitimate backslashes
- On Unix systems, backslashes are NOT path separators - they're used in escape sequences, regexes, etc.
- filepath.ToSlash() already handles path separators correctly per platform

## tests
- TestCLICommands/atmos_describe_config passes locally on macOS
- Windows tests already passing with previous logic
- Should fix macOS and Linux CI failures

* fix: use regex to replace backslashes in path contexts only

## what
- Changed sanitizeOutput to use regex for targeted backslash replacement
- Only replaces backslashes followed by path-like characters (alphanumeric, ., -, _, *, /)
- Preserves backslashes in escape sequence contexts (\n, \t, \r, etc.)
- Works cross-platform - handles Windows paths even on Unix/Linux

## why
- Previous OS-conditional approach broke Windows tests on Unix/Linux
- Tests need to verify Windows path handling on all platforms
- Escape sequences are already processed at runtime (appear as actual newlines/tabs)
- Backslashes in CLI output are either path separators or literal characters
- Regex approach safely handles both cases

## tests
- All TestSanitizeOutput tests pass on macOS
- Windows CI failure scenario tests work cross-platform
- Handles backslash paths: `D:\a\atmos\atmos` → `/absolute/path/to/repo`
- Preserves non-path backslashes if they appear

- Added github_token precondition to atmos_vendor_pull_with_globs
- Added github_token precondition to atmos vendor pull (tty and no-tty variants)

## why
- Without GitHub token, these tests hit API rate limits (60 req/hr)
- go-getter respects rate limits and backs off, causing 8+ minute waits
- With token, rate limit is 5000 req/hr and tests complete quickly
- Tests now skip immediately when token unavailable instead of hanging

## tests
- atmos_vendor_pull_with_globs: pulls from github.com with globs (took 25s without token)
- atmos vendor pull: pulls from github.com 3x (took 494s without token)

- Precondition is now used for general GitHub API access, not just OCI
- Previous message "required for pulling OCI images from ghcr.io" was misleading
- Tests use this for: OCI pulls, git clones from github.com, and avoiding rate limits
- Message should accurately reflect all use cases

* refactor: replace heuristic vendor URI parsing with go-getter API

## what
- Replace hardcoded domain pattern matching with go-getter's SourceDirSubdir() API
- Add comprehensive test coverage for Azure DevOps, Gitea, and self-hosted Git platforms
- Create documentation-first approach with PRD and user-facing URL syntax guide
- Extract helper functions with inline examples to reduce cyclomatic complexity

## why
- Previous implementation relied on observational heuristics (hardcoded .git///, .com///, .org/// patterns)
- go-getter provides official API for parsing source/subdirectory, eliminating guesswork
- Missing test cases for vendor URI variations (Azure DevOps _git/, self-hosted domains)
- Code complexity violated golangci-lint limits (cyclomatic complexity 15 > max 10)
- User feedback: "impossible to follow without examples" - needed inline documentation

## references
- Closes #1504 (DEV-3639: vendor pull failures after go-getter v1.7.9 update)

* refactor: extract named helper functions in vendor URI detection

## what
- Extract each URI check in `isLocalPath()` into dedicated helper functions
- Add comprehensive test coverage with 104 test cases across 6 functions
- Reduce cyclomatic complexity and improve code clarity

## why
- Each check in `isLocalPath()` now has a clear, named function describing its purpose
- Follows same pattern as existing `isDomainLikeURI()` and `isGitLikeURI()`
- Comprehensive tests ensure all edge cases are covered
- Makes the code easier to understand, test, and maintain

## changes

### New helper functions (vendor_uri_helpers.go)
- `hasLocalPathPrefix()` - checks for `/`, `./`, `../` prefixes
- `hasSchemeSeparator()` - checks for `://` or `::` scheme separators
- `hasSubdirectoryDelimiter()` - checks for `//` go-getter delimiter

### Refactored function
- `isLocalPath()` - now uses helper functions for clarity

### Comprehensive test coverage (vendor_uri_helpers_test.go)
- TestHasLocalPathPrefix: 11 test cases
- TestHasSchemeSeparator: 13 test cases
- TestHasSubdirectoryDelimiter: 12 test cases
- TestIsGitLikeURI: 13 test cases
- TestIsDomainLikeURI: 13 test cases
- TestIsLocalPath: 22 test cases (integration)

All 104 tests passing.

* docs: fix PRD to compare against main branch baseline

## what
- Correct PRD to accurately describe main branch baseline
- Remove incorrect reference to "hardcoded patterns" that never existed in main

## why
- The PRD incorrectly stated main branch had hardcoded `.git///`, `.com///`, `.org///` patterns
- Those patterns only existed in an intermediate commit (e881711) during this PR
- Main branch actually has NO triple-slash handling at all
- PRD should compare before/after against main, not intermediate PR states

## changes
- Updated "The Triple-Slash Problem" section to accurately reflect:
  - **Before (main)**: No triple-slash handling → silent failures
  - **After (this PR)**: Proper normalization using go-getter's SourceDirSubdir()

* fix: replace broad .Contains() checks with precise URL parsing

## what
- Replace overly broad `.Contains()` checks in Git/S3 URI detection
- Parse URLs properly to separate host from path before matching
- Add S3 `.amazonaws.com` auto-detection
- Remove duplicate `isGitLikeURI` function, keep only `isGitURI`
- Extract helper functions to reduce cyclomatic complexity

## why
- Previous `.Contains()` checks had false positives:
  - `www.gitman.com` incorrectly matched as Git URL
  - `evil.com/github.com/fake` incorrectly matched (github.com in path)
  - `/local/path/.git/config` incorrectly matched (.git in path)
- `s3::` prefix exists but S3 also auto-detects `.amazonaws.com` URLs
- No need for duplicate Git detection functions
- Cyclomatic complexity violation (12 > max 10)

## changes
- `isS3URI`: Now checks both `s3::` prefix and `.amazonaws.com/` pattern
- `isGitURI`: Properly parses URLs with helper functions:
  - `parseGitHostAndPath()`: Separates host from path
  - `isKnownGitHost()`: Checks known Git platforms
  - `hasGitExtension()`: Validates .git extension position
- Removed `isGitLikeURI` dead code path
- Added comprehensive test cases for edge cases
