v1.1.0-pre.2

🌟 Added

Partials

A Partial is a new feature that allows a test author to work with portions of the same C module under test differently from within the same test file.

With Partials, a test can now cause some functions in the source module under test to be mocked while other source functions are executed against assertions (see #936). Partials also allow testing of static and inline functions with no modification of your source code under test.

Documentation site

Ceedling is now complemented by a full, searchable documentation site.

A local verion of this site that is navigable with your web browser from your filesystem is included within Ceedling and exportable through CLI commands.

CLI additions

• ceedling help output provides links for further support and Github sponsorship.
• ceedling check validates your configuration and produces logs from processing it without executing a build.
• ceedling docs exports the new HTML-based documentation site to your local filesystem.

GCov plugin support for Modified Condition / Decision Coverage

Ceedling’s GCov plugin for coverage reporting now supports the Modified Condition / Decision Coverage abilities of GCC 14+ and optionally GCovr 8+.

System includes

Preprocessing support now properly distinguishes and handles system includes (#include <system.h>) and user includes (#include "user.h").

💪 Fixed

• #1011 Performance Improvements.
• #1014 Line Continuations not working in test name.
• #1015 directive-only issue.
• #1024 Fixed bug in options-handling for warnings log report.
• #358 Mocks with relative path in #include directive.
• #1128 Command line mixin precedence.
• Revisions to Mixin documentation correct merge order explanations and clarify Mixins generally.
• :gcov section of :flags is able to use filename matchers again (like :test section).
• Now properly reports timing for single-batch builds (i.e. non-parallel builds).
• PR #1126 fix for race condition in cache handling of #include listings in YAML files.
• PR #1056 fix for extracting #include directive filenames that contain dashes.
• Multiple fixes to #includes handling and encoding.
• Type handling in example temp_sensor project compatible with C23 (and previous C standards).
• #1120 An overly “helpful” holdover from Ceedling’s earliest days caused certain temporary and backup files to be cleaned that were needed by the user’s IDE and text editing tooling.

⚠️ Changed

• PR #1003 improvements for Mixin merges — clearer logging and edge case handling.
• Added warning logging if a Mixin contains mixins (nesting is not supported).
• Mixins now merge list content according to mixin priority. In all cases but one, a higher priority mixin inserts its list content before the content of the existing list to which it is merging. In the case of :tools :arguments lists, insertion occurs at the end of the arguments list to enable the typical CLI convention of rightmost argument having the highest priority.
• Significant refactoring and improvements to logging and parallel processing.
• Streamlined preprocessing, eliminating redundant steps and reducing memory usage.
• The GCov plugin now compiles all files with coverage (and filters out unneeded framework results) in order to meet the stricter coverage handling that began with GCC 14. This change is backwards and forwards compatible with virtually all versions of GCC and the GCov plugin’s supporting utilities.
• Resolved ambiguity in updated ceedling new handling from 0.31.1 to 1.0.0.
• Fixes for typos and grammar in documentation and logging.

👋 Removed

• CeedlingPacket.md user manual (superseded by new documentation site and local bundle).
• PluginDevelopmentGuide.md (superseded by new documentation site and local bundle).

Partials Pre-release

Automatic pre-release for 1.1.0-7343c1c

A Partial is a new feature that allows a test author to work with portions of the same C module under test differently from within the same test file. For example, a test can now cause some functions in the source module under test to be mocked while other source functions are executed against assertions (see #936).

Incremental Release

Partials

1. Testing and mocking any functions extracted from source through new Partials directive macros (available for use only in test files).
2. Exposing private (static) module variables for testing — i.e. stripping static and externing the variables.
3. Exposing private (static) function-scoped variables for testing — i.e. relocating the declarations from function to module scope, stripping static, renaming the variables to prevent name collisions, and externing the variables.
4. Remapping the location of functions within generated Partials to their original source files for proper coverage reporting.
5. Handling all core C language features including typedefs, macros, structs, unions, enums, etc.
6. Preserving order of C statements in source modules transformed into Partials.
7. Support for compiler extensions (e.g. MSVC __declspec and GCC __attribute()__).
8. GCov plugin
   1. Partials support for console reports
   2. Support for GCC 14+ (coverage reporting instrumentation changed with GCC 14)
   3. Support for modified condition/decision coverage when available in the toolchain

Fixes

• Fixed a line numbering problem for coverage reporting of partialized functions.

Other improvements

1. Preprocessing support for distinguishing and handling system includes (#include <system.h>) and user includes (#include "user.h").
2. Streamlined preprocessing, eliminating redundant steps and reducing memory usage.
3. ceedling check validates and processes project configuration without running anything.
4. The new Ceedling documentation system is incorporated into the CLI, including the new ceedling docs.

Documentation

This pre-release marks the transition away from unwieldy and dispersed monolithic markdown documents for Ceedling documentation. A totally revamped and fully web-based documentation system for Ceedling is nearing completion. A temporary dev version of the new Ceedling documentation is available online now and just refreshed. The documentation for Partials is ready to be used.

Known Issues

1. Preprocessing for Partials does not handle decorator macros (e.g. STATICINLINE) in function signatures.

v1.0.1

Bugfix Release 1.0.1 (full name 1.0.1-fb1ce6c)

Bug fixes:

• #978
• #979
• #980
• #981
• #982
• #985
• #988
• #888 & #977
• #996
• #998
• #1005
• Restored :use_mocks set to true in Ceedling defaults to match documentation and other mocking defaults in template projects.
• Resolved a preprocessing issue that could cause the content of a file having a similar filename to that of the file #includeing it to become mixed with that file.

v1.0.0

This Ceedling release is the most significant since the project was first posted to SourceForge.

Ceedling now runs in Ruby 3. Builds can now run much faster than previous versions because of parallelized tasks. In test suites, header file search paths, code defines, and tool run flags are now customizable per test executable. Ceedling now also offers integrated debugging options to find the cause of crashing tests.
