parzer 0.5.0

BUG FIX

• parse_lat() and parse_lon() (and the functions built on them) now return NA with a warning when minutes or seconds are not within 0/60, instead of silently converting them, e.g. “10°30,12345” (#60). Negative minutes or seconds, and a decimal degree or minute followed by another slot (e.g. “45.5 30”), now also give NA with a warning. A comma is a separator, not a decimal mark; this is now documented.
• parse_parts_lat() and parse_parts_lon() (and pz_degree(), pz_minute(), pz_second()) no longer lose the sign of values between -1 and 0: the sign now sits on the first non-zero part, e.g. -0.5 gives deg 0, min -30. They also no longer return 60 seconds, e.g. 10.35 is now 10 deg 21 min 0 sec, not 10 deg 20 min 60 sec.
• parse_llstr() now gives one clear warning (“could not split into latitude and longitude”) for each string it cannot split, and keeps the other rows. Before, each such string gave two confusing “no digits” warnings about an internal marker.
• The warning text for an invalid letter after degrees uses plain ASCII quotes.
• parse_lon_lat() and parse_hemisphere() now clean symbols like ° the same way parse_lat() and parse_lon() do (before, “40°25’” gave 40).
• Small numeric inputs such as 1e-5 are no longer misread as two slots, and a number too large for a double now gives NA with a warning instead of shifting the other slots.
• parse_lon_lat() and parse_hemisphere() now accept numeric and integer inputs, as documented.
• parse_llstr() now returns NA for unrecognized formats instead of two empty strings.
• Strings that cannot be converted (no digits, or more than 3 numeric slots) now give only one warning, with no spurious second range warning.
• Fixed undefined behaviour in parse_parts_lat() and parse_parts_lon() when a value could not be parsed (NA was cast to an integer).

MINOR IMPROVEMENTS

• Faster parsing: the C++ code no longer uses regular expressions (std::regex), numbers are read with std::stod instead of a new stream for each token, and parse_parts_*() no longer allocates an R list for each coordinate. parse_lat(), parse_lon(), parse_llstr() and parse_parts_lat() are about 9 to 12 times faster than in 0.4.4.
• withr is no longer a required dependency (it moved to Suggests). The Windows-only .Call() wrapper that forced the C locale (#31) is removed, because it only worked around a std::regex bug.
• parse_hemisphere() detects the sign of a value with std::signbit() instead of converting it to a string.
• Added performance tests (bench) to detect slowdowns, and a larger test suite (about 98% coverage).
• The use cases vignette now runs its sf and leaflet code only when both packages are installed.
• README: local coverage badge, and installation with pak::pkg_install().

parzer 0.4.4

BUG FIX

• Fixed a bug in longitude conversion where “74E5423” would be converted to NA while “74W5423” was correctly converted.
• Improved C++ management of NA values.

parzer 0.4.3

BUG FIX

• Removal of unnecessary files from the package.

parzer 0.4.2

MINOR IMPROVEMENTS

• C++ code was improved by replacing push.backs with direct assignations in vectors and also by passing arguments by reference where possible.
• Dependence on Rcpp was reduced

BUG FIX

• having spaces at the beginning of a string could lead to the disappearing of the negative sign

parzer 0.4.1

MINOR IMPROVEMENTS

• documentation and package description describe more clearly parzer core objective of parsing messy coordinates in character strings to convert them to decimal numeric values. Suggestion and work by @robitalec

ACKNOWLEDGEMENTS CHANGES

• new contributors to the package: @robitalec, @maelle and @yutannihilation
• new maintainer: @AlbanSagouis

parzer 0.4.0

MINOR IMPROVEMENTS

• performance improvement for internal function scrub(), used in most exported functions in parzer (#30) work by @AlbanSagouis
• work around for non-UTF8 MBCS locales: now all exported functions go through a modified .Call() in which we use withr::with_locale() if the user is on a Windows operating system (#31) (#32) work by @yutannihilation

parzer 0.3.0

BUG FIXES

• fix problem in parse_llstr(): on older R versions where stringsAsFactors=TRUE by default this function was returning strings as factors from an internal function that caused a problem in a subsequent step in the function (#29)

parzer 0.2.0

NEW FEATURES

• new contributor to the package @AlbanSagouis
• gains new function parse_llstr() to parse a string that contains both latitude and longitude (#3) (#24) (#26) (#28) work by @AlbanSagouis

MINOR IMPROVEMENTS

• updated scrub() internal function that strips certain characters to include more things to scrub (#25) work by @AlbanSagouis

parzer 0.1.4

MINOR IMPROVEMENTS

• add support to internal function for additional degree like symbols (#21)
• fix issue with parse_parts_lat()/parse_parts_lon() functions where an NA was causing warnings on the cpp side; on cpp side, now check for NA and return list of NAs instead of NAs passing through other code (#23)

parzer 0.1.0

NEW FEATURES

• Released to CRAN.
