In r-transit/gtfsio: Read and Write General Transit Feed Specification (GTFS) Files

gtfsio (development version)

gtfsio 1.2.0

import_gtfs() now reads geojson files as json (#37)
Updated gtfs reference implementation with new gtfs_reference dataset. get_gtfs_standard() has been deprecated.

Internally, fs is now used for file path manipulations (#39)

gtfsio 1.1.1

Now prevents export_gtfs() to save large round numbers in scientific notation. This was not exactly a bug, as the specification does not forbid it, but the behavior could interfere with the workflow of people using other applications (as shown in {gtfstools} #73). Also, improves the readability of the tables.

gtfsio 1.1.0

Fixed a bug in which import_gtfs() would append a .txt extension to non text files found inside the GTFS feed, which would lead to an error when attempting to unzip the feed. The function now ignores non text files when reading feeds, and raises an informative warning message if any of such files is found (#23).

import_gtfs() now accepts paths and URLs without .zip extension, as long as they still point to zip files (in other words, it accepts zip files that for some reason or another do not have .zip extension).

Started converting more warnings to messages when quiet = FALSE in import_gtfs() and export_gtfs().
Updated standards to read and write GTFS tables and fields in R due to changes in the specification.

gtfsio 1.0.0

import_gtfs() would raise a {bit64}-related warning when the first row of any table included a 64-bit integer. This is now fixed - when reading the first row to figure out which fields are present, all columns are read as character vectors.

Added (internal) input assertion functions, which declutter the input checking sections quite a bit.
Added new (internal) gtfsio_error() function, which raises a custom-classed error condition. All errors raised in gtfsio's exported functions inherit from gtfsio_error and <function_name>_error, which allows for easier and more clear error catching.

Files and fields checking functions had their names changed. They now use the singular form, instead of the plural (i.e. check_fields_exist() was substituted by check_field_exists()). This shouldn't raise reverse dependencies concern, because as of now only {gtfstools} dev version uses such functions, which is an easy fix that doesn't concern CRAN release.

gtfsio 0.2.0

import_gtfs() would ocasionally include the full path to a table to their name in a GTFS object (#17). Fixed by Mark Padgham (@mapdge) in #18.

Added new summary.gtfs method. Thanks Mark Padgham (@mapdge).
import_gtfs() has a new encoding parameter, used to handle encoded strings in their native encoding.

gtfsio 0.1.2

Fixed a bug (or perhaps, changed the behaviour) of check_fields_exist() and check_fields_types() when a lower-level test (i.e. if the file that holds such field exists, for example) failed. Now it returns FALSE instead of raising an error.

gtfsio 0.1.1

Fixed a bug in export_gtfs() when as_dir was set to TRUE and path was set to tempdir() in #15. The function now returns an (intentional) error if tempdir() is passed to path. Thanks Flavio Poletti (@polettif).

import_gtfs() has a new skip parameter. It may be used similarly to files, but you specify the files you don't want to read, instead of the ones you do. Thanks Flavio Poletti (@polettif).

gtfsio 0.1.0

First CRAN release!
