flexpolyline 0.3.0.9000

• Upgrade to current version of the flexpolyline [C++ implementation] (https://github.com/heremaps/flexible-polyline/blob/3e1ebc2e2ce39111b0e2e91260b98053ac965f77/cpp/include/hf/flexpolyline.h).
• Introduce encoder and decoder classes in C++ to separate responsibilities and improve error messages.
• Remove function set (set_third_dimension()) the third dimension type of a flexible polyline encoded string, as it can be done using decode() and encode().
• Split tests into encoding and decoding and add test helpers.
• Upgraded testthat edition by calling usethis::use_testthat(3).
• Replaced github actions with current versions from r-lib/actions.

flexpolyline 0.3.02023-02-12

• Update C++11 to current CRAN default of C++17.

flexpolyline 0.2.72023-01-08

• Fix missing missing inclusion of <cstdint>, closes #58.
• Resubmit to CRAN due to since the package was archived on 2022-12-27 as email to the maintainer was temporarily not deliverable.
• Updated r-lib/actions in github action R-CMD-check.yaml and pkgdown.yaml.

flexpolyline 0.2.62022-08-23

• Switch to HTML5 for documentation pages, closes #56.

flexpolyline 0.2.52021-11-19

• Changed workflow from git flow to trunc-based development. Removed develop branch. New features are merged directly into master and releases are tagged after CRAN has accepted the package submission, which triggers the documentation build.

flexpolyline 0.2.42021-10-02

• Adjust URLs to GitHub account due to renaming munterfinger to @munterfi.

flexpolyline 0.2.32021-04-30

• Skip encoding and decoding validation tests on CRAN due to minor deviations in the results due to rounding (half up vs. half even) on different platforms (e.g. Apple M1) at high precision values (closes #49)

flexpolyline 0.2.22021-04-20

• Fix wrong integer shift resulting in lost bits for precision values greater than 7 (see heremaps/flexible-polyline#36, closes #44).
• Fix CRAN note for a specified lazy data statement without data directory (closes #43).
• Use styler package and use tyler::tidyverse_style()to format the package.
• Solve lintr issues, except from line length issues (limit of 80 characters).

flexpolyline 0.2.12021-01-04

• Skip input tests of C++ binding on CRAN, closes #35.
• Added contribution guidelines, code of conduct and issue templates.

flexpolyline 0.2.02020-12-17

• Fix clang range-loop-analysis warning on macOS in flexpolyline.h (Apple clang version 12.0.0).
• Support for geometry types "POLYGON" and "POINT" in encode_sf() and decode_sf(), closes #31.
• Added functions to get (get_third_dimension()) and set (set_third_dimension()) the third dimension type of a flexible polyline encoded string.
• Sign in to CodeFactor.io and add badge to continuously track code quality.
• Use exception classes when throwing an exception in C++.
• Improve coverage of tests.

flexpolyline 0.1.12020-08-07

• Add ORCID to author field in DESCRIPTION.
• Limit the encoding check in the C++ binding test to 7 digits.
• Use explicit type casts before left shifting and reassigning (x <<= y) to avoid UBSAN runtime error ‘left shift of negative value’ in flexpolyline.h.

flexpolyline 0.1.02020-06-25

First release of the flexpolyline package, which provides a binding to the C++ implementation of the flexible polyline encoding by HERE. The flexible polyline encoding is a lossy compressed representation of a list of coordinate pairs or coordinate triples. The encoding is achieved by:

1. Reducing the decimal digits of each value;
2. encoding only the offset from the previous point;
3. using variable length for each coordinate delta; and
4. using 64 URL-safe characters to display the result.

The felxible polyline encoding is a variant of the Encoded Polyline Algorithm Format by Google.
