Refactor pushInterfaceToLua to delegate unsupported types (nil, bool/int/float/string/map/slice) recursively via new lvalueFromInterface helper. Simplify typed slice and map handlers, remove explicit nil case (now handled by lvalueFromInterface), eliminate redundant type switches in pushMapStringIntToLua and similar functions. Add new luajson.go with RegisterJSON, lua.JSONEncode/Decode bindings using lvalueFromInterface and Table2 Interface for bidirectional round-trips. Include comprehensive tests covering scalars, nested structures (e.g., kmindex response), arrays and error cases.
- **Bug fix**: Corrected logic in 4-mer calculation to properly handle sequences of length exactly three. Previously, such cases could produce invalid or unexpected results due to an incomplete guard condition (`length < 0`) which failed for ` length == 3` (where computed step size was zero). The fix ensures all sequences shorter than four bases are safely excluded.
- **Refactor**: Introduced a new internal utility function (`inverser_chaine`) to centralize string reversal logic, improving code maintainability and test coverage without affecting user-facing behavior.
- Improved concurrency safety by replacing the global HTTP client with a thread-safe, lazy-initialized instance using `sync.Once`. The new implementation enables connection pooling (`MaxIdleConnsPerHost`, connections per host) and dynamically configures pool size based on `obidefault.ParallelWorkers()`, ensuring robust behavior in multi-threaded Lua environments.

This release introduces dynamic batch flushing in the Distribute component, replacing the previous fixed-size batching with a memory- and count-aware strategy. Batches now flush automatically when either the maximum sequence count (BatchSizeMax()) or memory threshold (BatchMem()) per key is reached, ensuring more efficient resource usage and consistent behavior with the RebatchBySize strategy. The optional sizes parameter has been removed, and related code—including the Lua wrapper and worker buffer handling—has been updated for correctness and simplicity. Unused BatchSize() references have been eliminated from obidistribute.
Additionally, this release includes improvements to static Linux builds and overall build stability, enhancing reliability across deployment environments.
Replace the old fixed batch-size mechanism in Distribute with a dynamic strategy that flushes batches when either BatchSizeMax() sequences or BatchMem() bytes are reached per key. This aligns with the RebatchBySize strategy and removes the optional sizes parameter. Also update related code: simplify Lua wrapper to accept optional capacity, and fix buffer growth logic in worker.go using slices.Grow correctly. Remove unused BatchSize() usage from obidistribute.
This release focuses on improving build reliability, memory efficiency for large datasets, and portability of Linux binaries.

This commit fixes minor whitespace issues in the test script and adds new tests to ensure merge attribute consistency between in-memory and on-disk paths.
- Removed trailing spaces in log messages
- Added tests for merge consistency between in-memory and on-disk paths
- These tests catch a bug where shared classifier in on-disk dereplication path caused incorrect merged attributes
This commit introduces a new configuration module `obidefault` to manage progress bar settings, allowing users to disable progress bars via a `--no-progressbar` option. It updates various packages to conditionally display progress bars based on this new configuration, improving user experience by providing control over progress bar output. The changes also include improvements to progress bar handling in several packages, ensuring they are only displayed when appropriate (e.g., when stderr is a terminal and stdout is not piped).
This commit fixes an issue in the chunk processing logic where the wrong classifier instance was being reset and used for code generation. A local clone of the classifier is now created and used to ensure correct behavior during dereplication.
Modify CLIProgressBar function to check if stdout is a named pipe and disable the progress bar accordingly. This prevents the progress bar from being displayed when the output is redirected or piped to another command.
This commit addresses a bug in the super k-mer implementation where the minimizer bijection property was not properly enforced. The fix ensures that:
1. All k-mers within a super k-mer share the same minimizer
2. Identical super k-mer sequences have the same minimizer
The changes include:
- Fixing the super k-mer iteration logic to properly validate the minimizer bijection property
- Adding a comprehensive test suite (TestSuperKmerMinimizerBijection) that validates the intrinsic property of super k-mers
- Updating the .gitignore file to properly track relevant files
This resolves issues where the same sequence could be associated with different minimizers, violating the super k-mer definition.
This commit adds the implementation of the obisuperkmer command, including:
- The main command in cmd/obitools/obisuperkmer/
- The package implementation in pkg/obitools/obisuperkmer/
- Automated tests in obitests/obitools/obisuperkmer/
- Documentation for the implementation and tests
The obisuperkmer command extracts super k-mers from DNA sequences, following the standard OBITools architecture. It includes proper CLI option handling, validation of parameters, and integration with the OBITools pipeline system.
Tests cover basic functionality, parameter validation, output format, metadata preservation, and file I/O operations.
Ajout d'une documentation détaillée sur l'architecture des commandes OBITools, incluant la structure modulaire, les patterns architecturaux et les bonnes pratiques pour la création de nouvelles commandes.
This commit refactors the SuperKmer extraction functionality to use Go's new iterator pattern. The ExtractSuperKmers function is now implemented as a wrapper around a new IterSuperKmers iterator function, which yields results one at a time instead of building a complete slice. This change provides better memory efficiency and more flexible consumption of super k-mers. The functionality remains the same, but the interface is now more idiomatic and efficient for large datasets.

This commit simplifies the artifact packaging process by creating a single tar.gz file containing all binaries for each platform, instead of individual files. It also updates the release notes to reflect the new packaging approach and corrects the documentation to use the new naming convention 'obitools4' instead of '<tool>'.
Mise à jour du workflow de release pour utiliser ubuntu-24.04-arm au lieu de ubuntu-latest pour ARM64, et macos-15-intel au lieu de macos-latest pour macOS. Suppression de la compilation croisée pour ARM64 et ajustement de l'installation des outils de build pour macOS.
