For some back ends, you can display the file @dfn{annotated} with
per-line version information and using colors to enhance the visual
appearance, with the command @kbd{M-x vc-annotate}.
It creates a new buffer (the ``annotate buffer'') displaying the
file's text, with each part colored to show how old it is. Text
colored red is new, blue means old, and intermediate colors indicate
intermediate ages. By default, the time scale is 360 days, so that
everything more than one year old is shown in blue.
appearance, with the command @kbd{M-x vc-annotate}. It creates a new
buffer (the ``annotate buffer'') displaying the file's text, with each
part colored to show how old it is. Text colored red is new, blue means
old, and intermediate colors indicate intermediate ages. By default,
the color is scaled over the full range of ages, such that the oldest
changes are blue, and the newest changes are red.
When you give a prefix argument to this command, it uses the
minibuffer to read two arguments: which version number to display and
annotate (instead of the current file contents), and a stretch factor
for the time scale. A stretch factor of 0.1 means that the color
range from red to blue spans the past 36 days instead of 360 days. A
stretch factor greater than 1 means the color range spans more than a
year.
From the annotate buffer, you can use the following keys to browse the
annotations of past revisions, view diffs, or view log entries:
annotate (instead of the current file contents), and the time span in
days the color range should cover.
From the annotate buffer, these and other color scaling options are
available from the @samp{VC-Annotate} menu. In this buffer, you can
also use the following keys to browse the annotations of past revisions,
view diffs, or view log entries:
