lib/transform adds the transform library, supporting advanced path name
transformations for converting and renaming files and directories by applying
prefixes, suffixes, and other alterations.
It also adds the --name-transform flag for use with sync, copy, and move.
Multiple transformations can be used in sequence, applied in the order they are
specified on the command line.
By default --name-transform will only apply to file names. The means only the leaf
file name will be transformed. However some of the transforms would be better
applied to the whole path or just directories. To choose which which part of the
file path is affected some tags can be added to the --name-transform:
file Only transform the leaf name of files (DEFAULT)
dir Only transform name of directories - these may appear anywhere in the path
all Transform the entire path for files and directories
Example syntax:
--name-transform file,prefix=ABC
--name-transform dir,prefix=DEF
This removes logrus which is not developed any more and replaces it
with the new log/slog from the Go standard library.
It implements its own slog Handler which is backwards compatible with
all of rclone's previous logging modes.
Before this change, rclone had to load an entire directory into RAM in
order to sort it so it could be synced.
With directories with millions of entries, this used too much memory.
This fixes the probem by using an on disk sort when there are more
than --list-cutoff entries in a directory.

Before this change the --links flag when using the VFS override the
--links flag for the local backend which meant the local backend
needed explicit config to use links.
This fixes the problem by making the --links flag global and adding a
new --local-links flag and --vfs-links flags to control the features
individually if required.
After the config re-organisation, the setting of stringArray config
values (eg `--exclude` set with `RCLONE_EXCLUDE`) was broken and gave
a message like this for `RCLONE_EXCLUDE=*.jpg`:
Failed to load "filter" default values: failed to initialise "filter" options:
couldn't parse config item "exclude" = "*.jpg" as []string: parsing "*.jpg" as []string failed:
invalid character '/' looking for beginning of value
This was caused by the parser trying to parse the input string as a
JSON value.
When the config was re-organised it was thought that the internal
representation of stringArray values was not important as it was never
visible externally, however this turned out not to be true.
A defined representation was chosen - a comma separated string and
this was documented and tests were introduced in this patch.
This potentially introduces a very small backwards incompatibility. In
rclone v1.67.0
RCLONE_EXCLUDE=a,b
Would be interpreted as
--exclude "a,b"
Whereas this new code will interpret it as
--exclude "a" --exclude "b"
The benefit of being able to set multiple values with an environment
variable was deemed to outweigh the very small backwards compatibility
risk.
If a value with a `,` is needed, then use CSV escaping, eg
RCLONE_EXCLUDE="a,b"
(Note this needs to have the quotes in so at the unix shell that would be
RCLONE_EXCLUDE='"a,b"'
Fixes#8063
Before this change, rclone ignored the --password-command on the
rclone config setting except when decrypting an existing config file.
This change allows for offloading the password storage/generation into
external hardware key or other protected password storage.
Fixes#7859
