** COMMAND: patch
**
** Usage: %fossil patch SUBCOMMAND ?ARGS ..?
**
** This command is used to creates, view, and apply Fossil binary patches.
** A Fossil binary patch is a single (binary) file that captures all of the
** uncommitted changes of a check-out.  Use Fossil binary patches to transfer
** proposed or incomplete changes between machines for testing or analysis.
**
** > fossil patch create [DIRECTORY] FILENAME
**
**       Create a new binary patch in FILENAME that captures all uncommitted
**       changes in the check-out at DIRECTORY, or the current directory if
**       DIRECTORY is omitted.  If FILENAME is "-" then the binary patch
**       is written to standard output.
**
** > fossil patch apply [DIRECTORY] FILENAME
**
**       Apply the changes in FILENAME to the check-out a DIRECTORY, or
**       in the current directory if DIRECTORY is omitted. Options:
**
**           -f|--force     Apply the patch even though there are unsaved
**                          changes in the current check-out.
**           -n|--dryrun    Do nothing, but print what would have happened.
**           -v|--verbose   Extra output explaining what happens.
**
** > fossil patch push REMOTE-CHECKOUT
**
**       Create a patch for the current check-out, transfer that patch to
**       a remote machine (using ssh) and apply the patch there.  The
**       REMOTE-CHECKOUT is in one of the following formats:
**
**           *   DIRECTORY
**           *   HOST:DIRECTORY
**           *   USER@HOST:DIRECTORY
**
**       This command will only work if "fossil" is on the default PATH
**       of the remote machine.
**
** > fossil patch pull REMOTE-CHECKOUT
**
**       Create a patch on a remote check-out, transfer that patch to the
**       local machine (using ssh) and apply the patch in the local checkout.
**
**           -f|--force     Apply the patch even though there are unsaved
**                          changes in the current check-out.
**           -n|--dryrun    Do nothing, but print what would have happened.
**           -v|--verbose   Extra output explaining what happens.
**
** > fossil patch view FILENAME
**
**       View a summary of the the changes in the binary patch FILENAME.

# The "fossil patch" command

The "[fossil patch](/help?cmd=patch)" command is designed to transfer
uncommitted changes from one check-out to another, including transfering
those changes to other machines.

For example, if you are working on a Windows desktop and you want to
test your changes on a Linux server before you commit, you can use the
"fossil patch push" command to make a copy of all your changes on the
remote Linux server, where they can be tested.

>  fossil patch push linuxserver:/path/to/checkout

In the previous "linuxserver" is the name of the remote machine and
"/path/to/checkout" is an existing checkout directory for the same project
on the remote machine.

The "fossil patch push" command works by first creating a patch file,
then transfering that patch file to the remote machine using "ssh", then
applying the patch.  If you do not have ssh available, you can break these
steps apart as follows:

  1.  On the local machine: `fossil patch create mypatch.patch`
  2.  Move "mypatch.patch" to the remote machine.
  3.  On the remote machine: `fossil patch apply mypatch.patch`

## Setup

The "fossil push" and "fossil pull" commands will only work if you have
"ssh" available on the local machine and if "fossil" is on the default
PATH on the remote machine.

To check if Fossil is installed correctly on the remote, try a command
like this:

>  `ssh -T remote "fossil version"`

If the command above shows a recent version of Fossil, then you should be
set to go.  If you get "fossil not found", or if the version shown is too
old, put a newer fossil executable on the default PATH.  The default PATH
can be shown using:

>  `ssh -T remote 'echo $PATH'`

## Implementation Details

The "fossil patch create" command records all of the local, uncommitted
changes in an SQLite database file.  If the argument to "fossil patch create"
is a filename, then the patch-file database is written into that file.
If the argument is "-" then the database is written on standard output.

The "fossil patch apply" command reads the database that is the patch file
and applies it to the local check-out.  If a filename is given as an
argument, then the database is read from that file.  If the argument is "-"
then the database is read from standard input.

Hence the command:

> `fossil patch push remote:projectA`

Is equivalent to:

> `fossil patch create - | ssh -T remote 'cd projectA;fossil patch apply -'`

Likewise, a command like this:

> `fossil patch pull remote:projB

Could be entered like this:

> `ssh -T remote 'cd projB;fossil patch create -' | fossil patch apply -`

The "fossil patch view" command just opens the database file and prints
a summary of its contents on standard output.
