Hello all !

Version 2.1 of org-favtable.el has arrived at worg.
Please find it attached to this message or at worg:

The new Version supports normal org-mode links as well as numerical
references and has therefore been renamed from org-reftable to

Citing from its documentation:

;;; org-favtable.el --- Table of favorite references and links

;; Purpose:
;;  Mark and find your favorite items and org-locations easily: Create and
;;  update a lookup table of your favorite references and links. Often used
;;  entries automatically bubble to the top of the table; entering some
;;  keywords narrows it to just the matching entries; that way the right
;;  one can be picked easily.
;;  References are essentially small numbers (e.g. "R237" or "-455-"), as
;;  created by this package; links are normal org-mode links.

For a very simple example, please see the end of this message and find
three lines to add to your .emacs as well as a set of five nodes,
representing a simple org-mode setup.

Now, imagine that you want to visit the node for project "bar" but do not
remember its name. However, you recall that its related with "support".

So you type "C-+" to invoke org-favtable and then type "support" and
RET.  This will create an occur-Buffer and show you the three lines from
your table, which contain the keyword "support":

    |     | project | bar                            | support, legal                 |       8 | [2012-12-07 Fr] | b33e89f5-ab45-44a5-a63d-8644d48508db | [2012-12-08 Sa 23:37] |
    | R7  | project | Subproject one                 | support                        |       7 | [2013-01-24 Do] |      |                       |
    | R1  | project | foo                            | support                        |       1 | [2012-12-03 Mo] | 265c3656-afc3-4ec1-9b36-07ba1765fda9 |                       |

The first line ("bar") ist the one with the highest access count (8). It
appears right at the top, because the table is automatically sorted
after this number. And every time you access this node through
org-favtable, the count is incremented by one, so that your favorite
(i.e. most visited) entries always stay at the top.

So, you have found project "bar"; now just hit RET, to visit its node.

org-favtable.el has a lot more commands (e.g. to create new references
or search for existing ones in all your org-files); all of them, as well
as the proper setup, are explained in the documentation, which is also
accessible by simply invoking org-favtable.

Any questions, comments or suggestions are highly welcome !

regards, Marc-Oliver Ihm

  "List of commands known to org-favtable:

  occur: If you supply a keyword (text): Apply emacs standard
    occur operation on the table of favorites; ask for a
    string (keyword) to select lines. Occur will only show you
    lines which contain the given keyword, so you can easily find
    the right one. You may supply a list of words seperated by
    comma (\",\"), to select lines that contain any or all of the
    given words.

    If you supply a reference number: Apply emacs standard
    multi-occur operation all org-mode buffers to search for a
    specific reference.

    You may also read the note at the end of this help on saving
    the keystroke RET to accept this frequent default command.

  head: If invoked outside the table of favorites, ask for a
    reference number and search for a heading containing it. If
    invoked within favtable dont ask; rather use the reference or
    link from the current line.

  ref: Create a new reference, copy any previously selected text.
    If already within reftable, fill in ref-column.

  link: Create a new line in reftable with a link to the current node. 
    Do not populate the ref column; this can later be populated by
    calling the \"fill\" command from within the reftable.

  leave: Leave the table of favorites. If the last command has
    been \"ref\", the new reference is copied and ready to yank.

  enter: Just enter the node with the table of favorites.

  goto: Search for a specific reference within the table of

  help: Show this list of commands.

  +: Show all commands including the less frequently used ones
    given below. If \"+\" is followd by enough letters of such a
    command (e.g. \"+fi\"), then this command is invoked

  reorder: Temporarily reorder the table of favorites, e.g. by
    count, reference or last access.

  fill: If either ref or link is missing, fill it.

  sort: Sort a set of lines (either the active region or the
    whole buffer) by the references found in each line.

  update: For the given reference, update the line in the

  highlight: Highlight references in region or buffer.

  unhighlight: Remove highlights.

  missing : Search for missing reference numbers (which do not
    appear in the reference table). If requested, add additional
    lines for them, so that the command \"new\" is able to reuse

  statistics : Show some statistics (e.g. minimum and maximum
    reference) about favtable.

When prompting for a command, org-favtable puts the most likely
chosen one (e.g. \"occur\" or \"ref\") at the front of the list,
so that you may just type RET. 

If this command needs additional input (like e.g. \"occur\"), you
may supply this input right away, although you are still beeing
prompted for the command.


(defvar org-favtable--commands-some '(occur head ref link leave enter goto + help))

(defvar org-favtable--columns nil)

(defvar org-favtable-id nil 
  "Id of the Org-mode node, which contains the favorite table.

Read below, on how to set up things. See the help options
\"usage\" and \"commands\" for normal usage after setup.

Setup requires two steps:

 - Adjust your .emacs initialization file

 - Create a suitable org-mode node

Here are the lines, you need to add to your .emacs:

  (require 'org-favtable)
  ;; Good enough to start, but later you should probably 
  ;; change this id, as will be explained below
  (setq org-favtable-id \"00e26bef-1929-4110-b8b4-7eb9c9ab1fd4\")
  ;; Optionally assign a key. Pick your own favorite.
  (global-set-key (kbd \"C-+\") 'org-favtable)

Do not forget to restart emacs to make these lines effective.

As a second step you need to create the org-mode node, where your
reference numbers and links will be stored. It may look like

  * org-favtable
    :ID:       00e26bef-1929-4110-b8b4-7eb9c9ab1fd4

    |     |      | Comment, description, details  |         |         |               |
    | ref | link | ;c                             | count;s | created | last-accessed |
    |     | <4>  | <30>                           |         |         |               |
    | R1  |      | My first reference             |         |         |               |

You may just copy this node into one of your org-files.  Many
things however can or should be adjusted:

 - The node needs not be a top level node.

 - Its name is completely at you choice. The node is found
   through its ID.

 - There are three lines of headings above the first hline. The
   first one is ignored by org-favtable, and you can use them to
   give meaningful names to columns; the second line contains
   configuration information for org-favtable; please read
   further below for its format. The third line is optional and
   may contain width-informations (e.g. <30>) only.

 - The sequence of columns does not matter. You may reorder them
   any way you like; e.g. make the comment-column the last
   columns within the table. Columns ar found by their name,
   which appears in the second heading-line.

 - You can add further columns or even remove the
   \"Comment\"-column. All other columns from the
   example (e.g. \"ref\", \"link\", \"count\", \"created\" and
   \"last-accessed\") are required.

 - Your references need not start at \"R1\"; However, having an
   initial row is required (it serves as a template for subsequent

 - Your reference need not have the form \"R1\"; you may just as
   well choose any text, that contains a single number,
   e.g. \"reference-{1}\" or \"#7\" or \"++17++\" or \"-344-\". The
   function `org-favtable' will inspect your first reference and
   create all subsequent references in the same way.
 - You may want to change the ID-Property of the node above and
   create a new one, which is unique (and not just a copy of
   mine). You need to change it in the lines copied to your .emacs
   too. However, this is not strictly required to make things
   work, so you may do this later, after trying out this package.

Optionally you may tweak the second header line to adjust
`org-favtable' a bit. In the example above it looks like this
 (with spaces collapsed):

    | ref | link | ;c | count;s | created | last-accessed |

The different fields have different meanings:

 - ref : This denotes the column which contains you references

 - link : Column for org-mode links, which can be used to access
   locations within your files.

 - ;c : The flag \"c\" (\"c\" for \"copy\") denotes this column
   as the one beeing copied on command \"leave\". In the example
   above, it is also the comment-column.

 - count;s : this is the column which counts, how many time this
   line has been accessed (which is the key-feature of this
   package). The flag \"s\" stands for \"sort\", so the table is
   sorted after this column. You may also sort after columns
   \"ref\" or \"last-accessed\".

 - created : Date when this line was created.

 - last-accessed : Date and time, when this line was last accessed.

After this two-step setup process you may invoke `org-favtable'
to create a new favorite. Read the help option \"usage\" for
instructions on normal usage, read the help option \"commands\"
for help on single commands.

  "Mark and find your favorite items and org-locations easily:
Create and update a lookup table of your favorite references and
links. Often used entries automatically bubble to the top of the
table; entering some keywords narrows it to just the matching
entries; that way the right one can be picked easily.

References are essentially small numbers (e.g. \"R237\" or
\"-455-\"), as created by this package; links are normal org-mode
links. Within org-favtable, both are denoted as favorites.

Read below for a detailed description of this function. See the
help option \"setup\" or read the documentation of
`org-favtable-id' for setup instructions.

The function `org-favtable' operates on a dedicated table (called
the table or favorites or favtable, for short) within a special
Org-mode node. The node has to be created as part of your initial
setup. Each line of the favorite table contains:

 - A reference (optional)

 - A link (optional)

 - A number; counting, how often each reference has been
   used. This number is updated automatically and the table can
   be sorted according to it, so that most frequently used
   references appear at the top of the table and can be spotted

 - Its respective creation date

 - Date and time of last access. This column can alternatively be
   used to sort the table.

To be useful, your table of favorites should probably contain a
column with comments too, which allows lines to be selected by

The table of favorites is found through the id of the containing
node; this id should be stored within `org-favtable-id' (see there
for details).

The function `org-favtable' is the only interactive function of
this package and its sole entry point; it offers several commands
to create, find and look up these favorites (references and
links). All of them are explained within org-favtable's help.

Finally, org-favtable can also be invoked from elisp; the two
optional arguments accepted are:

         search : string to search for
           what : symbol of the command to invoke
 search-is-link : t, if argument search is actually a link

An example would be:

 (org-favtable \"237\" 'head)   ;; find heading with ref 237


  (interactive "P")

(let (within-node        ; True, if we are within node with favtable
