;;; Commentary

;; psvn.el is tested with GNU Emacs 21.3 on windows, debian linux,
;; freebsd5, red hat el4, ubuntu intrepid with svn 1.5.1

;; psvn.el needs at least svn 1.1.0
;; if you upgrade to a higher version, you need to do a fresh checkout

;; psvn.el is an interface for the revision control tool subversion
;; (see http://subversion.apache.org)
;; psvn.el provides a similar interface for subversion as pcl-cvs for cvs.
;; At the moment the following commands are implemented:
;;
;; M-x svn-status: run 'svn -status -v'
;; M-x svn-examine (like pcl-cvs cvs-examine) is alias for svn-status
;;
;; and show the result in the svn-status-buffer-name buffer (normally: *svn-status*).
;; If svn-status-verbose is set to nil, only "svn status" without "-v"
;; is run. Currently you have to toggle this variable manually.
;; This buffer uses svn-status mode in which the following keys are defined:
;; g     - svn-status-update:               run 'svn status -v'
;; M-s   - svn-status-update:               run 'svn status -v'
;; C-u g - svn-status-update:               run 'svn status -vu'

;; To use psvn.el put the following line in your .emacs:
;; (require 'psvn)
;; Start the svn interface with M-x svn-status

;; The latest version of psvn.el can be found at:
;;   http://www.xsteve.at/prg/emacs/psvn.el
;; Or you can check it out from the subversion repository:
;;   svn co http://svn.apache.org/repos/asf/subversion/trunk/contrib/client-side/emacs emacs-svn

;; TODO:
;; * shortcut for svn propset svn:keywords "Date" psvn.el
;; * docstrings for the functions
;; * perhaps shortcuts for ranges, dates
;; * when editing the command line - offer help from the svn client
;; * finish svn-status-property-set
;; * Add repository browser
;; * Get rid of all byte-compiler warnings
;; * SVK working copy support
;; * multiple independent buffers in svn-status-mode
;; There are "TODO" comments in other parts of this file as well.

;; For the not yet implemented commands you should use the command line
;; svn client. If there are user requests for any missing commands I will
;; probably implement them.

;; There is also limited support for the web-based software project management and bug/issue tracking system trac
;; Trac ticket links can be enabled in the *svn-log* buffers when using the following:
;; (setq svn-log-link-handlers '(trac-ticket-short))

;; ---------------------------
;; Frequently asked questions:
;; ---------------------------

;; Q1: I need support for user names with blanks/spaces
;; A1: Add the user names to svn-user-names-including-blanks and set the
;;     svn-pre-parse-status-hook.
;;     The problem is, that the user names and the file names from the svn status
;;     output can both contain blanks. Blanks in file names are supported.
;;     the svn-user-names-including-blanks list is used to replace the spaces
;;     in the user names with - to overcome this problem

;; Q2: My svn-update command it taking a really long time. How can I
;;     see what's going on?
;; A2: In the *svn-status* buffer press "s".

;; Q3: How do I enter a username and password?
;; A3: In the *svn-status* buffer press "s", switch to the
;;     *svn-process* buffer and press enter. You will be prompted for
;;     username and password.

;; Q4: What does "?", "M", and "C" in the first column of the
;;     *svn-status* buffer mean?
;; A4: "?" means the file(s) is not under Subversion control
;;     "M" means you have a locally modified file
;;     "C" means there is a conflict
;;     "@$&#!" means someone is saying nasty things to you


;; Comments / suggestions and bug reports are welcome!

;; Development notes
;; -----------------

;; "svn-" is the package prefix used in psvn.el.  There are also longer
;; prefixes which clarify the code and help symbol completion, but they
;; are not intended to prevent name clashes with other packages.  All
;; interactive commands meant to be used only in a specific mode should
;; have names beginning with the name of that mode: for example,
;; "svn-status-add-file" in "svn-status-mode".  "psvn" should be used
;; only in names of files, customization groups, and features.  If SVK
;; support is ever added, it should use "svn-svk-" when no existing
;; prefix is applicable.

;; Many of the variables marked as `risky-local-variable' are probably
;; impossible to abuse, as the commands that read them are used only in
;; buffers that are not visiting any files.  Better safe than sorry.

`svn-process-buffer-name' buffer before commencing.

CMDTYPE is a symbol such as 'mv, 'revert, or 'add, representing the
command to run.

ARGLIST is a list of arguments \(which must include the command name,
for example: '(\"revert\" \"file1\"\)
ARGLIST is flattened and any every nil value is discarded.

If the variable `svn-status-edit-svn-command' is non-nil then the user
can edit ARGLIST before running svn.

The hook svn-pre-run-hook allows to monitor/modify the ARGLIST."

  "Make a ui-status structure for a file in a svn working copy.
The initial values in the structure returned by this function
are good for a file or directory that the user hasn't seen before.

The ui-status structure keeps track of how the file or directory
should be displayed in svn-status mode.  Updating the svn-status
buffer from the working copy preserves the ui-status if possible.
User commands modify this structure; each file or directory must
thus have its own copy.

Currently, the ui-status is a list (USER-MARK USER-ELIDE).
USER-MARK is non-nil iff the user has marked the file or directory,
  typically with `svn-status-set-user-mark'.  To read USER-MARK,
  call `svn-status-line-info->has-usermark'.
USER-ELIDE is non-nil iff the user has elided the file or directory
  from the svn-status buffer, typically with `svn-status-toggle-elide'.
  To read USER-ELIDE, call `svn-status-line-info->user-elide'.

Call `svn-status-line-info->ui-status' to access the whole ui-status
structure."
