Since rclone version 1.61.0 the tree command uses ANSI color sequences in output by
default, but this lead to issues in Windows terminals that were not handling these (#6668).
This commit ensures the tree command uses the terminal package for output. It relies on
go-colorable to properly handle ANSI color sequences: If stdout is connected to a terminal
the escape sequences are decoded and the text are written with color formatting using
Windows Console API. If stdout is not connected to a terminal, e.g. redirected to file,
the escape sequences are stripped off. The tree command has its own method for writing
directly to a file, specified with flag --output, and then the output is not passed
through the terminal package and must therefore be written without ansi codes.
* fs: add TerminalColorMode type
* fs: add new config(flags) for TerminalColorMode
* lib/terminal: use TerminalColorMode to determine how to handle colors
* Add documentation for '--terminal-color-mode'
* tree: remove obsolete --color replaced by global --color
This changes the default behaviour of tree. It now displays colors by
default instead of only displaying them when the flag -C/--color was
active. Old behaviour (no color) can be achieved by setting --color to
'never'.
Fixes: #6604
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
