@ -3,12 +3,16 @@ Version 2.13.0.9 (dev) not released yet
**Incompatible changes**
------------------------
None so far
- New `memfile` & `memfile_size` fields in `symbol` for use with new output
option `BARCODE_MEMORY_FILE`
Changes
-------
- BMP: lessen heap memory usage by only `malloc()`ing a row
- GIF: lessen heap memory usage by paging; use standard colour char map
- Add `BARCODE_MEMORY_FILE` to `symbol->output_options` to allow outputting to
in-memory buffer `symbol->memfile` instead of to file `symbol->outfile`,
ticket #301

Current as of latest clang-tidy-18 from Ubuntu 22.04 apt package (2023-12-26)
Requires cmake in "build" sub-directory with -DCMAKE_EXPORT_COMPILE_COMMANDS=ON (for "build/compile_commands.json")
and -DCMAKE_BUILD_TYPE=Debug (so `assert()`s defined), and then make (for Qt generated includes).
In project root directory (warning, slow):
clang-tidy-18 backend/*.c frontend/*.c backend_qt/*.cpp frontend_qt/*.cpp -p build/compile_commands.json
For "backend_tcl", which has no "compile_commands.json", specify the tcl include directory, e.g.
clang-tidy-18 backend_tcl/*.c -- -I/usr/include/tcl8.6
Options are in ".clang-tidy" (in the project root directory). The excluded checks are
`clang-analyzer-security.insecureAPI.strcpy` (for `strcpy()`, `strcat()` etc), and
`clang-analyzer-security.insecureAPI.DeprecatedOrUnsafeBufferHandling` (for `sprintf()`).
The test suite (cmake given -DZINT_TEST=ON) can also be analysed with an additional check disabled:
clang-tidy-18 backend/tests/*.c frontend/tests/*.c backend_qt/tests/*.cpp \
-checks='-clang-analyzer-optin.performance.Padding' -p build/compile_commands.json
