@node Introduction
@chapter Introduction
@cindex introduction

rt-liberation is a GNU/Emacs package for working with the Request
Tracker (henceforth abbreviated as just ``RT'') software from Best
Practical Solutions. RT has an interactive Web interface, a command
line interface (the ``RT CLI''), and a REST interface. rt-liberation
uses the RT REST interface to communicate with the RT server.

rt-liberation allows sending search queries to the RT server, browsing
the resulting tickets, viewing the tickets' contents and performing
operations on the tickets.


@c --------------------------------------------------
@node Installation
@chapter Installation
@cindex installation

rt-liberation is available via GNU ELPA.

If you install rt-liberation manually instead you'll need to tell
Emacs where to find it, and tell Emacs to load the package:

@lisp
(add-to-list 'load-path "/PATH/TO/rt-liberation/")
@end lisp

@lisp
(require 'rt-liberation)
@end lisp


rt-liberation needs to be configured in your ~/.emacs, an ~/.rt-liber
file, or similar.

Tell rt-liberation where to find the RT server's REST interface:

@lisp
(setq rt-liber-rest-url "rt.example.org")
@end lisp

rt-liberation can issue a command to ``take'' a ticket (that is,
assign it to yourself). For this the variable @var{rt-liber-username}
must be set:

@lisp
(setq rt-liber-username "someuser")
@end lisp

rt-liberation can also launch a Web browser to visit a ticket. For
that to work the base URL needs to be set in
@var{rt-liber-base-url}. For example:

(setq rt-liber-base-url "https://rt.foo.org/")


@c --------------------------------------------------
@node Queries
@chapter Queries
@cindex queries

A typical RT server is meant to manage a large amount of tickets. Much
more that would be convenient to view all at once. Instead queries are
used to view only a subset of the tickets on the server.

rt-liberation has its own Sexp-based query language which maps to RT's
TicketSQL language.

@menu
* Query Compiler::              Compiling Emacs Lisp to TicketSQL.
* Query Language::              A description of the Sexp-based language.
@end menu


@c --------------------------------------------------
@node Query Compiler
@section Query Compiler
@cindex query compiler

In order to browse and view tickets a list of needs to be requested
from the RT server. Typically the tickets answer some kind of
criteria, for example ``tickets no older than a week owned by me which
have \``foobar\'' in their subject line''. In RT these criteria are
formulated with ``TicketSQL'' queries; a structured query language
specific to RT.

rt-liberation provides a query compiler function to compile Emacs Lisp
symbolic expressions into TicketSQL. The query compiler supports a
number of TicketSQL tokens.


@c --------------------------------------------------
@node Query Language
@section Query Language
@cindex query language

rt-liberation's Sexp-based query language covers a portion of the
TicketSQL language. Here are some of the supported TicketSQL tokens:
Boolean tokens as a means of combining query subsections: ``and'', ``or'',
``not''. LIKE attribute tokens: ``subject'', ``content''.

For example here is a query with both Boolean and LIKE tokens:

@lisp
(rt-liber-compile-query
    (and (queue "bugs")
         (content "gnu")))

==> "Queue = 'bugs' AND Content LIKE 'gnu'"
@end lisp

We can also express negation (note that the compiler produces "!=" and
"NOT LIKE" for negation depending on the context):

@lisp
(rt-liber-compile-query
 (and (queue "bugs")
      (not (owner "Nobody"))
      (not (content "sprigz"))
      (status "new")))

==> "Queue = 'licensing' AND Owner != 'Nobody' \
    AND Content NOT LIKE 'sprigz' AND Status = 'new'"
@end lisp

Attribute tokens which match an attribute to a specific field such as:
``owner'', ``status'' and ``queue''. Temporal tokens which limit the search
results to tickets within a certain time interval: ``created'' and
``lastupdated''. Note that temporal keywords such as ``created'' always
accept two arguments: BEFORE and AFTER. When either BEFORE or AFTER
aren't needed, use NIL instead.

One of the advantages of being able to express the TicketSQL queries
as Emacs Lisp is to be able to express queries using Emacs Lisp
functions.

Here is a slightly more involved example to illustrate:

@lisp
(rt-liber-compile-query
 (and (queue "bugs")
      (owner "me@@myaddress.com")
      (status "open")
      (lastupdated nil
                   (format-time-string
                     "%Y-%m-%d"
                     (seconds-to-time
                      (- (time-to-seconds (current-time))
                         (* 60 60 24 7)))))))

==> "Queue = 'bugs' AND Owner = 'me@@myaddress.com' AND Status = 'open' AND LastUpdated > '2009-03-30'"
@end lisp


Here is an example of how the ticket browser and compiler can be used
in function calls:

@lisp
(defun rt-liber-display-ticket (ticket-id)
  "Display ticket with TICKET-ID in the ticket-browser."
  (interactive "MTicket ID: ")
  (rt-liber-browse-query
   (rt-liber-compile-query
    (and (queue "complaints")
         (id ticket-id)))))
@end lisp


@c --------------------------------------------------
@node Ticket Browser
@chapter Ticket Browser
@cindex ticket browser

The ticket browser is a special buffer which provides a convenient
interface to the results of a server query. The ticket browser can be
started by invoking: (rt-liber-browse-query QUERY), where QUERY is a
TicketSQL query. The TicketSQL query can be entered manually as a
string or as the return value of the query compiler.

@deffn Function rt-liber-browse-query QUERY &optional NEW
Runs QUERY against the server and launches the browser.

If NEW is non-nil then the query results will be displayed in a new
buffer, otherwise the query results will override the contents of the
existing ticket browser buffer. If NEW is a string then that will be
the name of the new buffer.
@end deffn

The TicketSQL query can be the return value of the query compiler. For
example:

@lisp
(rt-liber-browse-query
 (rt-liber-compile-query
     (and (queue "bugs")
          (content "gnu")))
@end lisp


Since the return value of the query compiler is just a TicketSQL
string, the following is equivalent:

@lisp
(rt-liber-browse-query "Queue = 'bugs' AND Content LIKE 'gnu'")
@end lisp

The ticket browser defines a number of commands:

@table @kbd
@item q
@kindex q (ticket browser)
@findex rt-liber-browser-mode-quit
Bury the ticket browser buffer.

@item n
@kindex n (ticket browser)

@c --------------------------------------------------
@node Ticket Browser Display
@section Ticket Browser Display
@cindex ticket browser display function

The ticket browser displays the tickets in the browser by calling
@dfn{rt-liber-ticketlist-browser-redraw-f} which can be changed and
customized. Any implementation of
@dfn{rt-liber-ticketlist-browser-redraw-f} must leave point at the end
of the ticket text.

The ticket data itself can be displayed using rt-liberation ticket
format string %-sequences:

@table @asis
@item %i
ID number of the ticket in the RT database.
@item %s
Subject line.
@item %c
Ticket creation time. The format to display the time is specified in
the variable @var{rt-liber-browser-time-format-string}.
@item %S
Ticket status (``open'', ``new'' etc.)
@item %r
Whether the ticket is resolved.
@item %R
Requestor/s
@item %C
Creator of the ticket.
@item %o
Owner of the ticket.
@item %q
The queue originating the ticket.
@item %p
The numerical priority of the ticket
@end table

Here is an example implementation of
@dfn{rt-liber-ticketlist-browser-redraw-f} showing the use of the
%-sequences. Note the use of text properties to add color to ticket
text. The use of text properties as opposed to font-locking is meant
to ease customization because otherwise any change in ticket display
would break the font-locking regular expressions.

@lisp
(defun rt-liber-ticketlist-browser-redraw-f (ticket)
  "Display TICKET."
  (insert (rt-liber-format "[%c] %i" ticket))
  (add-text-properties (point-at-bol)
                       (point-at-eol)
                       '(face rt-liber-ticket-face))
  (newline)
  (insert (rt-liber-format "    [%S] %s" ticket))
  (newline)
  (insert (rt-liber-format "    %o <== %R" ticket)))
@end lisp

The function @dfn{rt-liber-high-priority-p} can be used to apply a
different face or text to a ticket if it is high priority. A ticket is
considered high priority if its value is strictly higher than
@var{rt-liber-browser-priority-cutoff}


@c --------------------------------------------------
@node Ticket Browser Sorting
@section Ticket Browser Sorting
@cindex ticket browser sorting

The tickets in the browser are displayed by default in reverse
chronological order. Ticket sorting is done by a call to
@dfn{rt-liber-browser-default-sorting-function}.

Other sorting orders can be used by binding
@dfn{rt-liber-browser-default-sorting-function} to a different
function. To ease writing such functions rt-liberation provides two
predicate functions to perform comparisons between ticket objects:

@defun rt-liber-lex-lessthan-p a b field
Return true if A is lexicographically less than B in FIELD.

Here is an example of sorting tickets lexicographically by owner name
using @dfn{rt-liber-lex-lessthan-p} (note that you can feed
@dfn{rt-liber-lex-lessthan-p} a date/time string and it will sort it
just fine except that it wouldn't make any sense):

@lisp
(defun rt-liber-sort-by-owner (ticket-list)
  "Sort TICKET-LIST lexicographically by owner."
  (rt-liber-sort-ticket-list
   ticket-list
   #'(lambda (a b)
       (rt-liber-lex-lessthan-p a b "Owner"))))
@end lisp

@end defun

@defun rt-liber-time-lessthan-p a b field
Return t if A is chronologically less than B in FIELD.

Here is an example of sorting tickets lexicographically by owner name
using @dfn{rt-liber-time-lessthan-p} (note that feeding
@dfn{rt-liber-time-lessthan-p} anything but a date/time string, in
this case ``Created'' contains a date, will result in an error being
signaled).

@lisp
(defun rt-liber-sort-by-time-created (ticket-list)
  "Sort TICKET-LIST in reverse chronological order."
  (reverse
   (rt-liber-sort-ticket-list
    ticket-list
    #'(lambda (a b)
        (rt-liber-time-lessthan-p a b "Created")))))
@end lisp

@end defun


@c -------------------------------------------------------------------
@node Ticket Browser Filtering
@section Ticket Browser Filtering
@cindex ticket browser filtering filter

The Ticket Browser can also filter out (that is, not display) certain
tickets based on particular criteria. This probably shouldn't be used
instead of a properly formed RT query, but when used in conjunction
with correctly formulated queries it becomes a powerful tool.

During ticket display processing the Ticket Browser will call the
function pointed to by @var{rt-liber-browser-default-filter-function}
on each ticket, passing the function the ticket alist as a single
argument. The function is set by default to
@dfn{rt-liber-default-filter-f}, which is a function which will
display all tickets and filter none.

If any tickets are filtered, the Ticket Browser will display the
filtered ticket count at the bottom ticket listing.

Here is a simple example of how to filter out all of the tickets which
have a status of ``deleted''.

First we define a custom filter function. Note how it accepts a single
argument, which is the ticket alist, and returns nil if the ticket is
to be filtered.

@lisp
(defun rt-liber-browser-deleted-filter (ticket)
  (not
   (and ticket
        (string= (cdr (assoc "Status" ticket))
                 "deleted"))))
@end lisp

Then we assign that function to be our default filtering function:

@lisp
(setq rt-liber-browser-default-filter-function
      'rt-liber-browser-deleted-filter)
@end lisp


@c -------------------------------------------------------------------
@node Multiple Ticket Browsers
@section Multiple Ticket Browsers
@cindex ticket browser multiple buffer

It is sometimes useful to rename the ticket browser buffer to
something more informative than the default
@var{rt-liber-browser-buffer-name}, especially if there are multiple
ticket browsers.

Changing a ticket browser's name can be done normally with
`rename-buffer', but it is also possible to name the ticket browser
when it is created. In the following example two ticket browser
buffers will be created displaying the query results and named
``*updated by supervisor*'' and ``*new tickets*'' respectively:

@lisp
(defun rt-liber-daily-rounds ()
  (interactive)

  (rt-liber-browse-query
   (rt-liber-compile-query
    (and (queue "complaints")
         (owner "lem.e.tweakit")
         (status "open")
         (lastupdatedby "molly.manager")))
   "*updated by supervisor*")

  (rt-liber-browse-query
   (rt-liber-compile-query
    (and (queue "complaints")
         (owner "Nobody")
         (status "new")))
   "*new tickets*"))
@end lisp


@c --------------------------------------------------
@node Ticket Viewer
@chapter Ticket Viewer
@cindex ticket viewer

The ticket viewer is an interface for viewing the contents of a
ticket. It provides font-locking to make reading the contents easier
via @var{rt-liber-viewer-font-lock-keywords} and a number of
key-bindings.

The ticket viewer provides key-bindings to help compose emails to send
to the RT email interface. The key-bindings for composing email
described below are generic, what actually happens when you invoke
them depends on the email-backend system you have installed into
rt-liberation. @file{rt-liberation-gnus.el} provides integration with
Gnus, @xref{Gnus Integration}.

Setting @var{rt-liber-jump-to-latest} to `t' will cause the viewer to
automatically scroll to the latest comment in a ticket when that
ticket is visited. By default @var{rt-liber-jump-to-latest} is set to
`nil'.

When in the ticket viewer buffer, invoking
@dfn{rt-liber-viewer-take-ticket} will ``take'' the ticket.

@table @kbd

@item q
@kindex q (ticket viewer)
@findex rt-liber-viewer-mode-quit
Bury the ticket viewer buffer.

@item n
@kindex n (ticket viewer)
@findex rt-liber-next-section-in-viewer

@end table


@c --------------------------------------------------
@node Gnus Integration
@chapter Gnus Integration
@cindex Gnus Integration

The file @file{rt-liberation-gnus.el} implements integration with Gnus
for composing emails. To enable the feature, `require' it after
loading rt-liberation:

@lisp
(require 'rt-liberation-gnus)
@end lisp

In order for rt-liberation-gnus to be useful a few variables need to
be specialized. The following is example code which sets these
variables. Below is a thorough description of those variables.

@lisp
(setq rt-liber-gnus-comment-address "our-rtserver-comment@@ourserver.org"
      rt-liber-gnus-address         "our-rtserver@@ourserver.org"
      rt-liber-gnus-subject-name    "ourserver.org")
@end lisp

@defopt rt-liber-gnus-address
@var{rt-liber-gnus-address} is the email address which is configured
in the RT server email interface for sending a response to the
ticket's requestor.
@end defopt
@defopt rt-liber-gnus-comment-address
@var{rt-liber-gnus-comment-address} is the email address which is
configured in the RT server email interface for adding a comment under
the ticket in question.
@end defopt
@defopt rt-liber-gnus-subject-name
@var{rt-liber-gnus-subject-name} is a string, typically included at
the beginning of the square brackets in the subject. The string is a
part of the subject line which helps the RT server recognize the
email.
@end defopt

Gnus posting styles controlled by @var{gnus-posting-styles} can be
customized for rt-liberation-gnus by using the variable
@var{rt-liber-gnus-p}, which is only non-nil when rt-liberation-gnus
launches a Gnus message buffer.

Here is example code which uses @var{rt-liber-gnus-p} to override the
signature in the default posting style with one special to
rt-liberation. Headers can be added and removed in a similar manner.

@lisp
(setq gnus-posting-styles
        '((".*"
           (name "Lemm E. Hackitt")
           (address "Lemm@@hack.it")
           (signature-file "~/sig.txt")
           ("X-Ethics" "Use GNU"))
          (rt-liber-gnus-p
           (signature-file "~/rt-liber-sig.txt"))))
@end lisp


Once rt-liberation-gnus is loaded and customized the key-bindings in
the Viewer will be able to call into it, @xref{Ticket Viewer}.


@c --------------------------------------------------
@node Tracking Updates
@chapter Tracking Updates
@cindex Tracking Updates

The functions in @file{rt-liberation-update.el} help keep up with
updates to the ticket database. To enable the feature, `require' it
after loading rt-liberation:

@lisp
(require 'rt-liberation-update)
@end lisp

Then set @var{rt-liber-update-default-queue} to be the name of the
queue to watch for updates. For example:

@lisp
(setq rt-liber-update-default-queue "complaints")
@end lisp

@defun rt-liber-update &optional no-update
@code{rt-liber-update} is an interactive function which runs a query
against the RT server asking for the tickets which have been updated
since the time @code{rt-liber-update} was last run (each time it runs,
it leaves a time-stamp). If no time-stamp is found, for instance when
you run @code{rt-liber-update} for the first time, today's date is
used.

With the NO-UPDATE prefix, @code{rt-liber-update} will not update the
time-stamp so that the next invocation will produce the same result.
@end defun


@c --------------------------------------------------
@node Batch Operations
@chapter Batch Operations
@cindex Batch Operations

The extension @file{rt-liberation-multi.el} implements performing
batch operations on groups of tickets. It works in two stages: First
mark an arbitrary number of tickets within the same buffer then call a
batch operation function on them. The batch operation functions work
the same way as function which work on single tickets only that they
iterate through all of the marked tickets.

To enable batch operations first load @file{rt-liberation-multi.el}:

@lisp
(require 'rt-liberation-storage)
@end lisp

@table @kbd
@item M
@kindex M (ticket browser)
@findex rt-liber-mark-ticket-at-point
Mark the ticket at point for future action. If the ticket at point is
already marked then unmark it.
@end table

@defun rt-liber-multi-set-status-open
Set the status of all the marked tickets to ``open''.
@end defun

@defun rt-liber-multi-set-status-resolved
Set the status of all the marked tickets to ``resolved.

@file{rt-liberation-storage.el} implements associating arbitrary
ancillary data with tickets. The data is stored locally and is not
sent to the RT server.

To enable local storage first load @file{rt-liberation-storage.el}:

@lisp
(require 'rt-liberation-storage)
@end lisp

Then enable the display of ancillary data with:

@lisp
(setq rt-liber-anc-p t)
@end lisp

The associated data is edited and displayed in the ticket browser with
the following command key:

@table @kbd
@item A
@kindex A (ticket browser)
@findex rt-liber-browser-ancillary-text
Associate text with the ticket at point. You will be prompted to enter
a string of text.
@end table

Once text is associated with a ticket it will be displayed alongside
that ticket in the ticket browser. This particular feature lends
itself to creating private annotations about tickets.

The implementation distributed with rt-liberation allows associating
text with tickets but is not limited to text. The same implementation
can be extended to associate any arbitrary data with any ticket.
