@chapter About PCL-CVS
@cindex About PCL-CVS

PCL-CVS is a front-end to CVS versions 1.9 and later.
It concisely shows the present status of a checked out module in an
Emacs buffer and provides single-key access to the most frequently used CVS
commands.
For Emacs users accustomed to VC, PCL-CVS can be thought of as a replacement
for VC-dired (@pxref{VC Dired Mode, , Dired under VC, emacs, The GNU
Emacs Manual}) specifically designed for CVS.

PCL-CVS was originally written many years ago by Per Cederqvist who
proudly maintained it until January 1996, at which point he released the
beta version 2.0b2 and passed on the maintainership to Greg A Woods.
Development stayed mostly dormant for a few years during which
version 2.0 never seemed to be able to leave the ``beta'' stage while a
separate XEmacs version was slowly splitting away.  In late 1998,
Stefan Monnier picked up development again, adding some major new
functionality and taking over the maintenance.

As of Emacs 21, PCL-CVS is part of the standard Emacs distribution.

@node   Installation,  , Contributors, About PCL-CVS
@section Installation
@cindex Installation

As mentioned above, PCL-CVS comes bundled with Emacs version 21.1 and
later.  If you're using Emacs 20, you can download an older version of
PCL-CVS from @uref{ftp://flint.cs.yale.edu/pub/monnier/pcl-cvs}.  That
version also works on XEmacs.

If you are running XEmacs 21.0 or later, PCL-CVS is available in
pre-compiled package form.  Please refer to the XEmacs manual for
instructions regarding package selection and installation.  Currently,
that PCL-CVS package also requires you to have installed the
@file{xemacs-base}, @file{elib}, and @file{dired} packages. 

If you have @TeX{} installed at your site, you can make a typeset manual
from @file{pcl-cvs.texi}.

@enumerate
@item
If PCL-CVS came with the Emacs distribution, type @kbd{make pcl-cvs.dvi}
in the @file{man} subdirectory of the Emacs source tree.
@item
Alternatively, run @TeX{} by typing @kbd{texi2dvi pcl-cvs.texi}.
@item
Convert the resulting device independent file @file{pcl-cvs.dvi} to a
form which your printer can output and print it.  If you have a
PostScript printer, there is a program, @code{dvi2ps}, which does.  There
is also a program which comes together with @TeX{}, @code{dvips}, which
you can use.

@node Getting started, Buffer contents, About PCL-CVS, Top
@chapter Getting started
@cindex Introduction
@cindex Example run
@cindex Sample session

This document assumes that you know what CVS is, and that you at least
know the fundamental concepts of CVS.  If that is not the case, you
should read the CVS documentation.  Type @kbd{info -f cvs} or @kbd{man
cvs}.

PCL-CVS is only useful once you have checked out a module.  So before
you invoke it, you must have a copy of a module somewhere in the file
system.

You can invoke PCL-CVS by typing @kbd{M-x cvs-examine @key{RET}}.
You can also invoke it via the menu bar, under @samp{Tools}.
Or, if you prefer, you can also invoke PCL-CVS by simply visiting the
CVS administrative subdirectory of your module, with a prefix argument.
For example, to invoke PCL-CVS in a separate frame, type @kbd{C-u C-x 5
f ~/my/project/CVS @key{RET}}.

The function @code{cvs-examine} will ask for a directory.  The command
@samp{cvs -n update} will be run in that directory.  (It should contain
files that have been checked out from a CVS archive.)  The output from
@code{cvs} will be parsed and presented in a table in a buffer called
@samp{*cvs*}.  It might look something like this:

@example
Repository : /usr/CVSroot
Module     : test
Working dir: /users/ceder/FOO/test


In directory .:
           Need-Update            bar
           Need-Update            file.txt
           Modified               namechange
           Need-Update            newer
In directory sub:
           Modified               ChangeLog

--------------------- End ---------------------
-- last cmd: cvs -f -z6 -n update -d -P --
@end example

In this example, your repository is in @file{/usr/CVSroot} and CVS has
been run in the directory @file{/users/ceder/FOO/test}.  The three files
(@file{bar}, @file{file.txt} and 
@file{newer}) that are marked with @samp{Need-Update} have been changed
by someone else in the CVS repository.  Two files (@file{namechange}
and @file{sub/ChangeLog}) have been modified locally, and need to be
checked in.

You can move the cursor up and down in the buffer with @kbd{C-n} and
@kbd{C-p} or @kbd{n} and @kbd{p}.  If you press @kbd{c} on one of the
@samp{Modified} files, that file will be checked in to the CVS
repository. @xref{Committing changes}.  You can also press @kbd{O} to
update any of the files that are marked @samp{Need-Update}.  You can
also run @kbd{M-x cvs-update @key{RET}} (bound to @kbd{M-u} in the
@samp{*cvs*} buffer) to update all the files.@refill

You can then press @kbd{=} to easily get a @samp{diff} between your
modified file and the base version that you started from, or you can
press @kbd{l} to get the output from @samp{cvs log}.  Many more such
commands are available simply by pressing a key (@pxref{Getting info
about files}).

@node Buffer contents, Selected files, Getting started, Top
@chapter Buffer contents
@cindex Buffer contents
@cindex @code{*cvs*} buffer contents

The display contains several columns, some of which are optional.
These columns are, from left to right:

@itemize @bullet

@item
Optionally, the head revision of the file.  This is the latest version
found in the repository.  It might also contain (instead of the head
revision) a sub status which typically gives further information about
how we got to the current state, for example @samp{patched},
@samp{merged}, @dots{}

@item
An asterisk when the file is @dfn{marked} (@pxref{Selected
files}).@refill

@item
The actual status of the file wrt the repository.  See below.

@item
Optionally, the base revision of the file.  This is the version
which the copy in your working directory is based upon.

@item
The file name.

@end itemize

The @samp{file status} field can have the following values:

@table @samp
@item Modified
The file is modified in your working directory, and there was no
modification to the same file in the repository.  This status can have
the following substatus:

@table @samp
@item merged
The file was modified in your working directory, and there were
modifications in the repository as well, but they were merged
successfully, without conflict, in your working directory.@refill
@end table

@item Conflict
A conflict was detected while trying to merge your changes to @var{file}
with changes from the repository.  @var{file} (the copy in your
working directory) is now the output of the @code{rcsmerge} command on
the two versions; an unmodified copy of your file is also in your
working directory, with the name @file{.#@var{file}.@var{version}},
where @var{version} is the RCS revision that your modified file started
from.  @xref{Viewing differences}, for more details.@refill

A conflict can also come from a disagreement on the existence of the file
rather than on its content.  This case is indicated by the following
possible substatus:

@table @samp
@item removed
The file is locally removed but a new revision has been committed to
the repository by someone else.

@item added
The file is locally added and has also been added to the repository
by someone else.

@item modified
The file is locally modified but someone else has removed it from the
repository.
@end table

@item Added
The file has been added by you, but it still needs to be checked in to
the repository.@refill

@item Removed
The file has been removed by you, but it still needs to be checked in to
the repository.  You can resurrect it by typing @kbd{a} (@pxref{Adding
and removing files}).@refill

@item Unknown
A file that was detected in your directory, but that neither appears in
the repository, nor is present on the list of files that CVS should
ignore.@refill

@item Up-to-date
The file is up to date with respect to the version in the repository.
This status can have a substatus of:

@table @samp
@item added
You have just added the file to the repository.@refill

@item updated
The file was brought up to date with respect to the repository.  This is
done for any file that exists in the repository but not in your source,
and for files that you haven't changed but are not the most recent
versions available in the repository.@refill

@item patched
The file was brought up to date with respect to the remote repository by
way of fetching and applying a patch to the file in your source.  This
is equivalent to @samp{updated} except that CVS decided to use a hopefully
more efficient method.@refill

@item committed
You just committed the file.@refill
@end table

@item Need-Update
Either a newer version than the one in your source is available in the
repository and you have not modified your checked out version, or the
file exists in the repository but not in your source.  Use
@samp{cvs-mode-update} bound to @kbd{O} to update the file.@refill

@item Need-Merge
You have modified the checked out version of the file, and a newer
version is available in the repository.  A merge will take place when
you run a @samp{cvs-update}.

@item Missing
The file has been unexpectedly removed from your working directory
although it has not been @samp{cvs remove}d.
@end table

@node Selected files, Commands, Buffer contents, Top
@chapter Selected files
@cindex Selected files
@cindex Marked files
@cindex File selection
@cindex Active files
@cindex Applicable

Many of the commands work on the current set of @dfn{selected} files
which can be either the set of marked files (if any file is marked and
marks are no ignored) or whichever file or directory the cursor is on.

If a directory is selected but the command cannot be applied to a
directory, then it will be applied to the set of files under this
directory which are in the @samp{*cvs*} buffer.

@findex cvs-mode-force-command
@findex cvs-allow-dir-commit
Furthermore, each command only operates on a subset of the selected
files, depending on whether or not the command is @dfn{applicable} to
each file (based on the file's status).  For example,
@code{cvs-mode-commit} is not applicable to a file whose status is
@samp{Need-Update}.  If it should happen that PCL-CVS guesses the
applicability wrong, you can override it with the special prefix
@code{cvs-mode-force-command} normally bound to @kbd{M-f} (and file a
bug report).  The applicability rule can be slightly changed with
@code{cvs-allow-dir-commit} and @code{cvs-force-dir-tag}.

By default, marks are always in effect (you may change this, however, by
setting the variable @code{cvs-default-ignore-marks}) except for the
commands that @samp{tag} or @samp{diff} a file (which can be changed
with the variable @code{cvs-invert-ignore-marks}).

In addition, you may use the special prefix @code{cvs-mode-toggle-marks}
normally bound to @key{T} to toggle the use of marks for the following
command.

This scheme might seem a little complicated, but once one gets used to
it, it is quite powerful.

For commands to mark and unmark files, see @ref{Marking files}.

@cindex Creating the *cvs* buffer

Most commands in PCL-CVS require that you have a @samp{*cvs*}
buffer.  The commands that you use to get one are listed below.
For each, a @samp{cvs} process will be run, the output will be parsed by 
PCL-CVS, and the result will be printed in the @samp{*cvs*} buffer (see
@ref{Buffer contents}, for a description of the buffer's contents).

@table @kbd
@item M-x cvs-update
Run a @samp{cvs update} command.  You will be asked for the directory 
in which the @samp{cvs update} will be run.

@item M-x cvs-examine
Run a @samp{cvs -n update} command.  This is identical to the previous
command, except that it will only check what needs to be done but will
not change anything.  You will be asked for the directory in
which the @samp{cvs -n update} will be run.

@item M-x cvs-status
Run a @samp{cvs status} command.  You will be asked for the directory 
in which the @samp{cvs status} will be run.

@item M-x cvs-checkout
Run a @samp{cvs checkout} command.  You will be asked for the directory
in which the @samp{cvs update} will be run and the module to be checked
out.

@item M-x cvs-quickdir
Populate the @samp{*cvs*} buffer by just looking at the @file{CVS/Entries}
files.  This is very much like @code{cvs-examine} except that it does
not access the CVS repository, which is a major advantage when the
repository is far away.  But of course, it will not be able to detect
when a file needs to be updated or merged.
@end table

@findex cvs-dired-action
@findex cvs-dired-use-hook
The first four of
those commands are also reachable from the menu bar
under @samp{Tools->PCL-CVS}.  Finally, an alternative way is to visit
the CVS administrative subdirectory in your work area with a simple
prefix argument.  For example @kbd{C-u C-x C-f ~/my/work/CVS @key{RET}}.  This
by default runs @code{cvs-quickdir} but the specific behavior can be
changed with @code{cvs-dired-action} and @code{cvs-dired-use-hook}.

By default, the commands above will descend recursively into
subdirectories.  You can avoid that behavior by including @samp{-l} in
the flags for the command.  These flags can be set by giving a prefix
argument to the command (e.g., by typing
@kbd{C-u M-x cvs-update @key{RET} -l @key{RET}}).


@node Setting flags, Updating the buffer, Entering PCL-CVS, Commands
@section Setting flags for CVS commands
@cindex Optional switches to CVS
@cindex Command-line options to CVS

This section describes the convention used by nearly all PCL-CVS
commands for setting optional flags sent to CVS.  A single @kbd{C-u}
prefix argument is used to cause the command to prompt for flags to be
used for the current invocation of the command only.  Two @kbd{C-u} prefix
arguments are used to prompt for flags which will be set permanently, for the
current invocation and all that follow, until the flags are changed, or
unless temporary flags are set which override them.

Perhaps an example or two is in order.  Say you are about to add a
binary file to the repository, and want to specify the flags @samp{-kb}
to @samp{cvs add}.  You can type @kbd{C-u a -kb @key{RET}}, enter the
description, and the file will be added.  Subsequent @samp{cvs add}
commands will use the previously prevailing flags.

As a second example, say you are about to perform a diff and want to see
the result in unified diff format, i.e. you'd like to pass the flag
@samp{-u} to both @samp{cvs diff} and @samp{diff}.  You'd also like all
subsequent diffs to use this flag.  You can type @kbd{C-u C-u = -u @key{RET}}
and the diff will be performed, and the default flags will be set to
@code{("-u")}.  You can of course override this flag for a single diff
by using a single @kbd{C-u} prefix argument.

@cindex Special prefix
In addition to this, some commands can take @dfn{special prefix} arguments.
These work as follows: When called with a @kbd{C-u} prefix, the user is
prompted for a new value of the special prefix and the special prefix is
activated for the next command.  When called without the @kbd{C-u}
prefix, the special prefix is re-activated (with the same value as last
time) for the next command.  Calling the prefix command again when it's
already activated deactivates it.  Calling it with the @kbd{C-u C-u}
prefix activates it for all subsequent commands until you deactivate it
explicitly.  The special prefixes are:

@table @kbd
@item T
Toggles whether or not marks will be active in the next command.@refill

@item b
Provide the next command with a branch (can be any version
specifier) to work on.@refill

@item B
Secondary branch argument.  Only meaningful if @kbd{b} is also used.
It can be used to provide a second branch argument to
@code{cvs-mode-diff} or to @code{cvs-mode-update}.

@item M-f
Forces the next command to apply to every selected file rather than only
to the ones PCL-CVS thinks are relevant.

@samp{*cvs-commit*}.@refill

@item
You type in the log message describing the changes you're about to
commit (@pxref{Log Edit Mode}).

@item
When you're happy with it, you type @kbd{C-c C-c} to do the actual
commit.@refill
@end enumerate

There's no hidden state, so you can abort the process or pick it up
again at any time.

@vindex log-edit-confirm@r{ (variable)}
The set of files actually committed is really decided only during the
very last step, which is a mixed blessing.  It allows you to go back and
change your mind about which files to commit, but it also means that you
might inadvertently change the set of selected files.  To reduce the
risk of error, @kbd{C-c C-c} will ask for confirmation if the set of
selected files has changed between the first step and the last.  You can
change this last detail with @code{log-edit-confirm}.

As for the difference between @kbd{c} (i.e. @code{cvs-mode-commit}) and
@kbd{C} (i.e. @code{cvs-mode-commit-setup}) is that the first gets you
straight to @samp{*cvs-commit*} without erasing it or changing anything
to its content, while the second first erases @samp{*cvs-commit*}
and tries to initialize it with a sane default (it does that by either
using a template provided by the CVS administrator or by extracting a
relevant log message from a @file{ChangeLog} file).

If you are editing the files in your Emacs, an automatic
@samp{revert-buffer} will be performed.  (If the file contains
@samp{$@asis{Id}$} keywords, @samp{cvs commit} will write a new file with
the new values substituted.  The auto-revert makes sure that you get
them into your buffer).  The revert will not occur if you have modified
your buffer, or if @samp{cvs-auto-revert} is set to
@samp{nil}.

@cindex Log Edit mode
@cindex mode, Log Edit
Buffers for entering/editing log messages for changes which are about
to be committed are put into Log Edit mode.

Sometimes the log buffer contains default text when you enter it,
typically the last log message entered.  If it does, mark and point
are set around the entire contents of the buffer so that it is easy to
kill the contents of the buffer with @kbd{C-w}.

@findex log-edit-insert-changelog
If you work by writing entries in the @file{ChangeLog}
(@pxref{(emacs)Change Log}) and then commit the change under revision
control, you can generate the Log Edit text from the ChangeLog using
@kbd{C-a C-a} (@kbd{log-edit-insert-changelog}).  This looks for
entries for the file(s) concerned in the top entry in the ChangeLog
and uses those paragraphs as the log text.  This text is only inserted
if the top entry was made under your user name on the current date.
@xref{(emacs)Change Logs and VC}, for the opposite way of
working---generating ChangeLog entries from the revision control log.

In the Log Edit buffer, @kbd{C-c C-f} (@kbd{M-x log-edit-show-files})
shows the list of files to be committed in case you need to check
that.

When you have finished editing the log message, type @kbd{C-c C-c} to
exit the buffer and commit the change.

that visit a file that is committed will be automatically reverted.
This variable defaults to @samp{t}. @xref{Committing changes}.@refill

@item cvs-update-prog-output-skip-regexp
The @samp{-u} flag in the @file{modules} file can be used to run a command
whenever a @samp{cvs update} is performed (see @code{cvs(5)}).  This regexp
is used to search for the last line in that output.  It is normally set
to @samp{$}.  That setting is only correct if the command outputs
nothing.  Note that PCL-CVS will get very confused if the command
outputs @emph{anything} to @code{stderr}.

@item cvs-cvsroot
This variable can be set to override @samp{CVSROOT}.  It should be a
string.  If it is set, then every time a @code{cvs} command is run, it
will be called as @samp{cvs -d @var{cvs-cvsroot}@dots{}}.  This can be
useful if your site has several repositories.

@item log-edit-require-final-newline
@c wordy to avoid unhderfull hbox
When you enter a log message by typing into the
@samp{*cvs-commit-message*} buffer, PCL-CVS normally automatically
inserts a trailing newline, unless there already is one.  This behavior
can be controlled via @samp{cvs-commit-buffer-require-final-newline}.
If it is @samp{t} (the default behavior), a newline will always be
appended.  If it is @samp{nil}, newlines will never be appended.  Any
other value causes PCL-CVS to ask the user whenever there is no trailing
newline in the commit message buffer.

@findex cvs-mode-changelog-commit
@item log-edit-changelog-full-paragraphs
If this variable is non-@code{nil}, include full @file{ChangeLog}
paragraphs in the CVS log created by @samp{cvs-mode-changelog-commit}. 
This may be set in the local variables section of a @file{ChangeLog}
file, to indicate the policy for that @file{ChangeLog}.

@cindex @file{ChangeLog} paragraphs
A @dfn{@file{ChangeLog} paragraph} is a bunch of log text containing no
blank lines; a paragraph usually describes a set of changes with a
single purpose, but perhaps spanning several functions in several files.
Changes in different paragraphs are unrelated.

You could argue that the CVS log entry for a file should contain the
full @file{ChangeLog} paragraph mentioning the change to the file, even though
it may mention other files, because that gives you the full context you
need to understand the change.  This is the behavior you get when this
variable is set to @code{t}, the default.

On the other hand, you could argue that the CVS log entry for a change
should contain only the text for the changes which occurred in that
file, because the CVS log is per-file.  This is the behavior you get
when this variable is set to @code{nil}.

@findex cvs-mode-ignore@r{, and @file{.cvsignore} sorting}
@item cvs-sort-ignore-file
If this variable is set to any non-@samp{nil} value, the
@file{.cvsignore} file will always be sorted whenever you use
@samp{cvs-mode-ignore} to add a file to it.  This option is on by
default.

@item cvs-filename-face
used to highlight file names.

@item cvs-unknown-face

need no further action.

If you find a bug or misfeature, don't hesitate to tell us!  Send email
to @email{bug-gnu-emacs@@gnu.org} which is gatewayed to the newsgroup
@samp{gnu.emacs.bugs}.  Feature requests should also be sent there.  We
prefer discussing one thing at a time.  If you find several unrelated
bugs, please report them separately.  If you are running PCL-CVS under
XEmacs, you should also send a copy of bug reports to
@email{xemacs-beta@@xemacs.org}.

If you have problems using PCL-CVS or other questions, send them to
@email{help-gnu-emacs@@gnu.org}, which is gatewayed to the
@samp{gnu.emacs.help} newsgroup.  This is a good place to get help, as
is @email{cvs-info@@gnu.org}, gatewayed to @samp{gnu.cvs.help}.

If you have ideas for improvements, or if you have written some
extensions to this package, we would like to hear from you.  We hope that
you find this package useful!

Below is a partial list of currently known problems with PCL-CVS version
2.0.

@table @asis
@item Unexpected output from CVS
Unexpected output from CVS may confuse PCL-CVS.  It will create
warning messages in the @samp{*cvs*} buffer alerting you to any parse errors.
If you get these messages, please send a bug report to the email
addresses listed above.  Include the contents of the @samp{*cvs*} buffer, the
output of the CVS process (which should be found in the @samp{*cvs-tmp*}
buffer), and the versions of Emacs, PCL-CVS and CVS you are using.
