\end{options}
Each patch may depend on any number of previous patches. If you choose to
make your patch depend on a previous patch, that patch is required to be
applied before your patch can be applied to a repository. This can be used, for
example, if a piece of code requires a function to be defined, which was
defined in an earlier patch.
If you want to manually define any dependencies for your patch, you can use
the \verb!--ask-deps! flag, and darcs will ask you for the patch's
dependencies.
It is possible to record a patch which has no actual changes but which
has specific dependencies. This type of patch can be thought of as a
``partial tag''. The \verb!darcs tag! command will record a patch
with no actual changes but which depends on the entire current
inventory of the repository. The \verb!darcs record --ask-deps! with
no selected changes will record a patch that depends on only those
patches selected via the \verb!--ask-deps! operation, resulting in a
patch which describes a set of patches; the presence of this primary
patch in a repository implies the presence of (at least) the
depended-upon patches.

\begin{options}
--pipe
\end{options}
If you run record with the \verb!--pipe! option, you will be prompted for
the patch date, author, and the long comment. The long comment will extend
until the end of file or stdin is reached (ctrl-D on Unixy systems, ctrl-Z
on systems running a Microsoft OS).
This interface is intended for scripting darcs, in particular for writing
repository conversion scripts. The prompts are intended mostly as a useful
guide (since scripts won't need them), to help you understand the format in
which to provide the input. Here's an example of what the \verb!--pipe!
prompts look like:
\begin{verbatim}
What is the date? Mon Nov 15 13:38:01 EST 2004
Who is the author? David Roundy
What is the log? One or more comment lines
\end{verbatim}
\begin{options}
--interactive
\end{options}
By default, \verb!record! works interactively. Probably the only thing you need
to know about using this is that you can press \verb!?! at the prompt to be
shown a list of the rest of the options and what they do. The rest should be
clear from there. Here's a
``screenshot'' to demonstrate:
\begin{verbatim}
hunk ./hello.pl +2
+#!/usr/bin/perl
+print "Hello World!\n";
Shall I record this patch? (2/2) [ynWsfqadjk], or ? for help: ?
How to use record...
y: record this patch
n: don't record it
w: wait and decide later, defaulting to no
s: don't record the rest of the changes to this file
f: record the rest of the changes to this file
d: record selected patches
a: record all the remaining patches
q: cancel record
j: skip to next patch
k: back up to previous patch
h or ?: show this help
<Space>: accept the current default (which is capitalized)
\end{verbatim}
What you can't see in that ``screenshot'' is that \verb!darcs! will also try to use
color in your terminal to make the output even easier to read.
