In zip: Cross-Platform 'zip' Compression

zip 2.3.0

• zip now handles large zip files on Windows (#65, #75, #79, @weshinsley).

• zip now behaves better for absolute paths in mirror mode, and when the paths contain a : character (#69, #70).

• zip::unzip() now uses the process's umask value (see umask(2)) on Unix if the zip file does not contain Unix permissions (#67).

• Fix segmentation fault when zip file can't be created (#91, @zeehio)

• Fix delayed evaluation error on zipfile when zip::zip() is used (#92, @zeehio)

• New deflate() and inflate() functions to compress and uncompress GZIP streams in memory.

zip 2.2.2

• No user visible changes.

zip 2.2.1

• No user visible changes.

2.2.0

• Header values (of version made by and external attributes) are now correctly read and written on big-endian systems (#68).

• zip_list() now also returns crc32 and offset (#74, @jefferis).

2.1.1

This version has no user visible changes.

2.1.0

• unzip_process() now does not fail randomly on Windows (#60).

• Now all functions handle Unicode paths correctly, on Windows as well (#42, #53).

• unzip_process() now works when R library is on different drive than exdir on Windows (#45)

• zip functions now have a mode argument to choose how files and directories are assembled into the archive. See the docs for details.

• zip functions now have a root argument, zip changes the working directory to this before creating the archive, so all files are relative to root.

• zip() and zip_append() are not deprecated any more, as it was hard to achieve the same functionality with the other zip functions.

2.0.4

• unzip_process() prints better error messages to the standard error, and exits with a non-zero status, on error.

2.0.3

• zipr() and zipr_append() get an include_directories = TRUE argument, that can be used to omit directory entries from the zip archive. These entries may cause problems in MS Office docx files (#34).

2.0.2

• zip_process() and unzip_process() can now pass extra arguments to processx::process (#32).

• unzip_process() now makes sure the exdir path is created with forward slashes on Windows, mixing forward and backward slashes can cause errors.

2.0.1

• zip() and zip_append() are now soft-deprecated, please use zipr() and zipr_append() instead.

2.0.0

• New zipr() and zipr_append(), they always store relative file names in the archive.

• New unzip() function for uncompressing zip archives.

• New zip_process() and unzip_process() functions to create or uncompress an archive in a background process.

• zip(), zipr(), zip_append() and zipr_append() all include directories in the archives, empty ones as well.

• zip(), zipr(), zip_append() and zipr_append() all add time stamps to the archive and zip_list() returns then in the timestamp column.

• zip(), zipr(), zip_append() and zipr_append() all add file and directory permissions to the archive on Unix systems, and zip_list() returns them in the permissions column.

• zip_list() now correctly reports the size of large files in the archive.

• Use miniz 2.0.8 internally.

1.0.0

First public release.
