16 # This file is the default header for new Org files in Worg. Feel free
17 # to tailor it to your needs.
19 Some org-mode related project currently being developed in worg.
25 Located in the =contrib/lisp/= directory of org-mode.
27 A utility for collecting properties from the headers in an org file,
28 running the properties through arbitrary elisp functions, and
29 presenting the results in a table.
31 The functionality of this tool is similar to the functionality of
32 [[info:org:Capturing%20column%20view][info:org:Capturing column view]], but this has support for processing
33 prior to the generation of the table.
35 Here is a simple example application of this utility.
37 #+begin_comment ems better example
38 it might be better to put an exercise example here if someone has one.

79 * Fireforg, a Firefox extension for org interaction (EXPERIMENTAL)
83 Fireforg is a Firefox extension, that interacts with Emacs Org-mode.
85 For the displayed URL it shows the associated tags in the status bar
86 and allows to show a list of annotations that can be instantly visited
89 Additionally, in every website it marks all links that occur in the agenda files.
91 For every link in the agenda files the previous heading and its tags
92 are associated with it.
94 For *scientific use*, it is possible to *send BibTeX entries* for
95 sites supported by the Zotero plugin to Emacs. [[*Import%20BibTeX%20using%20Zotero][Additional steps]] are
96 necessary for this to work.
100 :ID: 13179b21-d70a-4255-a8f1-9f4e4e729074
102 The following notes should be taken into consideration before using Fireforg:
103 - On the Emacs side a registry of all links in the agenda files will
104 be generated and saved in plain text onto the harddrive.
105 - The generation can take very a long time depending on the size of
106 the agenda files and the number of links in them.
107 - The generated file can become quite large.
108 - When files are *encrypted* having some information from them in
109 plain text on the harddrive might not be what you want.
110 - Firefox will read and look through the registry file for the
111 currently viewed site. Depending on the size of the registry file
112 and on the options [[id:e77f15a8-c358-44fd-a207-8c422fee2d1e][Lookup links on page load]] and [[id:d73476f3-6c09-479c-abea-f33d3e0e074a][Prefetch links to extract DOI]]
113 this might slow down the browsing experience.
117 - Install org-protocol according to its [[file:org-contrib/org-protocol.org][manual]] and *please verify
118 that it's working* using either the bookmarks or by invoking it directly in the shell:
119 : emacsclient 'org-protocol://remember://w/http%3A%2F%2Forgmode.org%2F/Org-Mode%3A%20Your%20Life%20in%20Plain%20Text%20-%20Mozilla%20Firefox/'
120 - Get org-fireforg.el from [[fireforgrepofile:lisp/org-fireforg.el][here]] and put the following into your
121 =.emacs= *after* the section that initializes org-protocol:
122 : (add-to-list 'load-path "~/path/to/org/fireforg/")
123 : (require 'org-fireforg)
124 : (org-fireforg-registry-insinuate)
126 and as the last line of the file:
127 : (org-fireforg-registry-initialize t)
129 Note that creating the registry can take a long time depending on
130 the size of the agenda files and the number of links in them.
132 - Visit [[fireforgrepofile:build/fireforg.xpi][this link]] with Firefox, confirm installation of the extension and restart.
134 (Windows users will have to adjust: org-fireforg-registry-file-xml in Emacs
135 and "registry-file" in Fireforgs preferences to be the same file.)
137 *** Installation from a git clone
139 It is also possible to clone the git repository first, using:
140 : git clone http://repo.or.cz/r/org-fireforg.git
141 , install lisp/org-fireforg.el according to the instructions above
142 and add a file named =fireforg@burtzlaff.de= containing the path
143 to the "fireforg" subdirectory into =~/.mozilla/firefox/<your
144 profile>/extensions/=.
146 In my setup for example there is a file
147 =~/.mozilla/firefox/4xyx9l73.default/extensions/fireforg@burtzlaff.de=
149 : /home/andy/projects/org-fireforg/fireforg
151 A restart of Firefox is required for this to work.
154 *** The status bar entry
156 If the currently viewed url is found in your agenda files, the number
157 of occurrences together with all associated tags will be shown in the
158 status bar. A left click on the status bar entry will show a list of
159 all headings associated with the currently viewed url. Selecting one
160 of them lets Emacs visit that heading.
162 For example, this heading in one of your agenda files:
163 : * Greatest tool in the world [[https://orgmode.org/][Org mode]] :Org:
164 will yield the following when visiting https://orgmode.org/ and left clicking:
166 [[file:images/screenshots/org-fireforg-screenshot.png]]
168 *** Triggering store-link and remember
169 Right clicking on the status bar entry shows a menu that let's you
170 trigger org-protocol's "store-link" and "remember".
172 There is an entry for every remember template listed in the [[*List%20of%20characters%20specifying%20available%20remember%20templates][preferences]].
174 The entries in the submenu "All tabs" will call remember for every tab
175 in the current window. This option only makes sense if a remember
176 template is used, that stores the note automatically ("%!" in the template string), e.g.:
177 : * %:description \n %:link %!
179 *** Mark links that occur in the agenda files in websites
181 Whenever a site is loaded, Fireforg will alter the style of all links
182 in it, that occur in the agenda files. The tooltip of those links is
183 set to contain the annotations.
185 This feature can be turned off using an [[*Lookup%20links%20on%20page%20load][option]] in the [[*Preferences][preferences
186 dialog]]. [[*CSS%20style%20string%20for%20links%20with%20annotations][The CSS-style]] used for marking the link and [[*Overwrite%20tooltip%20for%20links%20with%20annotations][whether or
187 not the tooltip is set]] is also customizable.
189 *** Context menu for links
191 The context menu (accessible by right clicking on a link) has a
192 submenu "Fireforg", where all annotations for that link are listed:
194 [[file:images/screenshots/org-fireforg-screenshot-context-menu.png]]
196 ** Import BibTeX using Zotero
198 :ID: e6fc94c6-7fef-4348-b998-f6a6f58eded8
200 Fireforg is able to retrieve BibTex entries for the all sites
201 supported by [[http://www.zotero.org/][Zotero]]. To achieve this the following additional steps
203 - Install Zotero 1.0.10 from the [[http://www.zotero.org/][Zotero Website]]
204 - Set "Inject Zotero" in Fireforg's preference dialog
205 [fn:ffprefdiag: Fireforg's preference dialogue is accessible in
206 Firefox's menu under Tools->Add-ons->Fireforg->Preferences].
208 *Warning: On restart a small function is injected into Zotero to
209 catch imported entries. The change to the code is minimal and
210 non-permanent. In a worst case scenario Zotero's database might
211 get corrupted, though that hasn't happened yet.*
215 Whenever a single entry (*not* a collection) is imported into Zotero -
216 e.g. by clicking the white "document" symbol that appears to the right
217 in the url bar if Zotero supports importing the current site - it is
218 automatically exported to BibTeX and sent to org mode using
219 org-protocol. In Emacs it is put into the kill ring in a format
220 depending on the variable =org-fireforg-received-bibtex-format=:
222 - =nil=: The BibTeX entry is passed directly into the kill ring.
223 - =heading= (Default): A heading is generated with the BibTeX
224 fields as properties with prefix "BIB_":
225 : * [[<link to site>][<Title>]]
227 : :CUSTOM_ID: <BibTeX key>
228 : :BIB_entryType: <article, ...>
233 - =headingWithPropsAndBibTeXContent=: a heading with properties as
234 described above is generated and the entry in BibTeX format is
236 - =headingWithBibTeXContent=: same as the previous one but without the properties
238 If the 'url' field is a *static URL*, the link to it will be highlighted
239 in search results in every search engine. Otherwise the option
240 [[id:3ab02821-03c4-4fa7-9a3a-e9701245c5d8][Match sites by comparing their DOI with saved bibliography entries]] might help.
242 To export BibTeX information from all headings in the current buffer
243 with at least the "BIB_entryType" property call:
244 - =org-fireforg-export-bibtex-to-file= to export to a file
245 - =org-fireforg-export-bibtex-to-new-buffer= to export into a new buffer
247 *** Digital Object Identifiers (DOI)
249 :ID: fbd09ba5-6632-40df-bcc0-8e5a7b9eb7a7
251 If a BibTeX entry contains a field 'doi', a URL will be generated by
252 prepending "http://dx.doi.org/" to the corresponding property
253 'BIB_doi'. It will be handled as any other URL. There is a
254 [[id:3ab02821-03c4-4fa7-9a3a-e9701245c5d8][corresponding functionality in the plugin]] that allows to associated
255 pages despite non-static URLs.
257 Fireforg's preference dialogue is accessible in Firefox's menu
258 under Tools->Add-ons->Fireforg->Preferences
260 The file containing an xml tree with all link-headline associations
261 generated from the agenda files. You should not need to change
262 this. It has to be same as the customizable variable
263 =org-fireforg-registry-file-xml= in Emacs.
264 ***** Lookup links on page load
266 :ID: e77f15a8-c358-44fd-a207-8c422fee2d1e
268 When enabled, all links in a web page that have headlines
269 associated with them are marked. This is achieve by adding the
270 following CSS style string to the element:
271 Depending on the size of the registry this *might slow Firefox down*.
272 ***** CSS style string for links with annotations
273 The string that is appended to the CSS =style= string of a link
274 element, if annotations for it exist.
275 ***** Overwrite tooltip for links with annotations
276 If enabled, sets the tooltip for the links, for which
277 annotations exist to contain those annotations.
279 After restarting Firefox, a function in the Zotero code gets altered
280 so that all BibtTeX entries (*not* collections) that are imported are
281 sent using org-protocol and are handled in Emacs according to the
282 variable =org-fireforg-received-bibtex-format= as described [[* Import BibTeX using Zotero][here]]. Due
283 to [[* Technical note][design choices in Zotero]] this is a bit fragile and can yield errors
284 and *might possibly even break Zotero's database*. It is not advisable
285 to use Zotero for production when enabling this option in Fireforg.
286 ***** Match sites by comparing their DOI with saved bibliography entries
288 :ID: 3ab02821-03c4-4fa7-9a3a-e9701245c5d8
290 Extract the Digital Object Identifier (DOI) from a page, prepend
291 "http://dx.doi.org/" to it and look up the resulting URL.
293 If using a bibliography format [[id:e6fc94c6-7fef-4348-b998-f6a6f58eded8][with properties]], a [[id:fbd09ba5-6632-40df-bcc0-8e5a7b9eb7a7][URL is
294 generated in the same way from the value of the field "BIB_doi"
295 if it exists]]. Thus documents can be matched regardless of the
296 possibly non-static URL.
297 ***** Prefetch links to extract DOI
299 :ID: d73476f3-6c09-479c-abea-f33d3e0e074a
301 *Prefetch all links in a page* after it is loaded, extract the
302 DOIs - if any - and [[id:fbd09ba5-6632-40df-bcc0-8e5a7b9eb7a7][use it to find annotations]]. This requires
303 the option [[id:3ab02821-03c4-4fa7-9a3a-e9701245c5d8][Match sites by comparing their DOI with saved
304 bibliography entries]] to be set.
306 A site is only prefetched once in every Firefox session, because the
307 associated URL mapping is saved until Firefox is restarted.
309 *All links starting with "http" will be prefetched (except for
310 files with extensions: PDF, GIF, PNG or SWF).* This option can
311 also be toggled in the status bar menu.
313 *This option will generate additional network traffic and might
314 slow the browsing experience*
315 ***** List of characters specifying available remember templates
316 For every character in this list an entry in the [[*Triggering%20store-link%20and%20remember][popup menu]] will
317 be generated, that triggers remember with the template
318 associated with the character.
319 ***** Enable workaround for Mac
320 see [[* Workaround for the inability to register a protocol in Firefox on the Mac][here]]
321 ***** Temporary file for Mac workaround
322 see [[* Workaround for the inability to register a protocol in Firefox on the Mac][here]]
324 ** Workaround for the inability to register a protocol in Firefox on the Mac
326 A long known bug in Firefox on the Mac is reported to stop protocol
327 registration from working. To work around this Fireforg is able to
328 write the org-protocol urls to a temporary file, that is read every
329 second and, if non empty, passed to emacsclient and emptied.
332 - check "Enable workaround for Mac" in Fireforg's preference dialogue [fn:ffprefdiag]
333 - get pull.sh from [[http://repo.or.cz/w/org-fireforg.git?a=blob_plain;f=ff_mac_workaround/pull.sh;hb=HEAD][the repository]] and run it.
337 To avoid confusion, always update both org-fireforg.el and the plugin.
339 The plugin has to be uninstalled and then reinstalled as described
340 above. Automatic updating will be used when the testing phase is over.
342 ** Bugreporting and discussion
344 - Discussions go to the org-mode list.
345 - Bugreports are better not sent to the list, but rather directly to
346 the [[mailto:andreas%20AT%20burtzlaff%20DOT%20de][author]] (Please add "[Fireforg]" to the subject.).
348 *** A checklist for bug tracing
350 To create a test case put:
351 : * Greatest tool in the world [[https://orgmode.org/][Org mode]] :Org:
352 into one of your agenda files and save it.
354 If problems arise please go through this checklist to locate the problem:
356 - Does the file "~/.org-fireforg-registry.xml" exist and does it contain "orgmode.org"?
357 - *No on either*: Send me the last content of the Messages buffer in Emacs
358 - *Yes*: In the Firefox menu: "Tools"->"Error console" look for
359 errors containing: "chrome://fireforg/" and send them to me.
363 Different instances of Zotero's Translator object seem to share state
364 in a non-obvious way. This makes coding very fragile and even lets
365 some imports fail (silently) after Fireforg has injected its code. The
366 failure when importing collections is somehow related to this. While
367 I find it a strange design choice, it is not in my power to change it.
368 * MEMO org-mail-htmlize: Create MIME messages based on Org
370 ** Representing a MIME internet message
372 A MIME internet message consists of one or more MIME entities. Each
373 MIME entity is of a distinct type and subtype, has a body and
374 optional MIME headers related to its content.
376 A MIME entity is represented as a list:
378 (TYPE SUBTYPE BODY CONT-HEAD)
380 - TYPE :: Symbol of MIME media type (e.g. text, video, audio).
382 - SUBTYPE :: Symbol of MIME media subtype (e.g. plain, html).
384 - BODY :: String with entity body -or- list of other MIME entities.
386 - CONT-HEAD :: List of cons with content related MIME header
387 fields. The name of the header field without the
388 prefix "Content-" is car, the value cdr.
392 #+begin_src emacs-lisp
393 '(text html "<h1>Headline</h1>" ((disposition . inline)))
396 For messages of type multipart the body consists of a list of one
397 or more MIME entities.
399 #+begin_src emacs-lisp
400 '(multipart alternative
401 '((text plain "* Headline")
402 (text html "<h1>headline</h1>")))
405 ** MIME delimiters of SEMI and mml
407 The MIME delimiters are defined in an association list with a
408 symbol of the library's name as key and delimiter format strings as
409 values. For each library there are three formatstrings.
411 (SYMBOL DELIM-SINGLE DELIM-SINGLE-CONT DELIM-MULTI)
413 - DELIM-SINGLE :: Denoting a single MIME entity.
415 Strings are passed in this order:
425 - DELIM-SINGLE-CONT :: Format of content header strings.
427 Strings are passed in this order:
431 2. header field value
433 - DELIM-MULTI :: Enclosing parts of a multipart entity.
435 Strings are passed in this order:
443 #+begin_src emacs-lisp
444 (setq org-mail-htmlize-mime-delimiter-alist
445 '((semi "\n--[[%s/%s%s]]\n%s" "\ncontent-%s: %s" "\n--<<%s>>-{\n%s\n--}-<<%s>>")
446 (mml "\n<#part type=\"%s/%s\"%s>\n%s" " %s=\"%s\"" "\n<#multipart type=\"%s\">\n%s\n<#/multipart>")))
451 This generic function returns a string representation with MIME
452 delimiters depending on the variable =org-mail-htmlize-mime-lib=.
454 #+begin_src emacs-lisp
455 (setq org-mail-htmlize-mime-lib 'semi)
458 #+begin_src emacs-lisp
459 (defun org-mail-htmlize-mime-entity (type subtype body
461 "Return string representation of MIME entity.
463 TYPE is the type of entity body.
464 SUBTYPE is the subtype of body.
465 BODY is the body of the entity. Either a string with the body
466 content or a list with one ore more MIME entities.
467 Optional argument CONT-HEAD is a list of cons with content
468 specific headers, name in car and value in cdr."
469 (let ((delimlst (assoc org-mail-htmlize-mime-lib
470 org-mail-htmlize-mime-delimiter-alist)))
471 (if (eq type 'multipart)
472 (format (nth 3 delimlst) subtype
473 (mapconcat (lambda (b)
474 (apply 'org-mail-htmlize-mime-entity
475 (car b) (cadr b) (cddr b)))
478 (format (nth 1 delimlst)
480 (mapconcat (lambda (h)
481 (format (nth 2 delimlst) (car h) (cdr h)))
488 *** How to handle charset information?
490 *** How to attach files?
492 The generic function expects BODY either be a string or a list.
493 Attaching binary file (image, etc.) requires to encode it so the
494 message will pass the message system. So we /might/ use kind of a
495 encoder (e.g. base64) on our own.
497 Or, what seems a cleaner solution: Use attachment function of the
498 respective MIME mode. To achive this: Introduce third possibility
499 for BODY: A cons with the filename in car and symbol of the
502 (FILENAME . FUNCTION)
504 #+begin_src emacs-lisp
505 '(image jpeg ("/path/to/image" . org-mail-htmlize-add-attachment))
508 The function =org-mail-htmlize-add-attachment= is called with file
509 name as argument and calls the appropriate function depending on
510 =org-mail-htmlize-mime-lib= and returns a string
512 - with the encoded body
516 - the complete MIME entity
518 Side effect: The user might be prompted for attachment settings
519 (e.g. encoding). But, on the other hand: We delegate the job of
520 creating the attachment to the library that is responsible for
523 ** Quotes from the specs
525 *** MIME multipart: Notion of structured, related body parts
527 :Created: [2010-03-25 Do]
530 - [[http://tools.ietf.org/html/rfc2046.html#section-5.1.1][RFC2046, 5.1.1]]
533 NOTE: Conspicuously missing from the "multipart" type is a notion of
534 structured, related body parts. It is recommended that those wishing
535 to provide more structured or integrated multipart messaging
536 facilities should define subtypes of multipart that are syntactically
537 identical but define relationships between the various parts. For
538 example, subtypes of multipart could be defined that include a
539 distinguished part which in turn is used to specify the relationships
540 between the other parts, probably referring to them by their
541 Content-ID field. Old implementations will not recognize the new
542 subtype if this approach is used, but will treat it as
543 multipart/mixed and will thus be able to show the user the parts that
546 *** MIME multipart: order of entities inside a multipart
548 :Created: [2010-03-25 Do]
551 - [[http://tools.ietf.org/html/rfc2046.html#section-5.1.3][RFC2046, 5.1.3]]
556 The "mixed" subtype of "multipart" is intended for use when the body
557 parts are independent and need to be bundled in a particular order.
558 Any "multipart" subtypes that an implementation does not recognize
559 must be treated as being of subtype "mixed".
563 - [[http://tools.ietf.org/html/rfc2046.html#section-5.1.4][RFC2046, 5.1.4]]
566 5.1.4. Alternative Subtype
568 The "multipart/alternative" type is syntactically identical to
569 "multipart/mixed", but the semantics are different. In particular,
570 each of the body parts is an "alternative" version of the same
573 Systems should recognize that the content of the various parts are
574 interchangeable. Systems should choose the "best" type based on the
575 local environment and references, in some cases even through user
576 interaction. As with "multipart/mixed", the order of body parts is
577 significant. In this case, the alternatives appear in an order of
578 increasing faithfulness to the original content. In general, the
579 best choice is the LAST part of a type supported by the recipient
580 system's local environment.
584 In general, user agents that compose "multipart/alternative" entities
585 must place the body parts in increasing order of preference, that is,
586 with the preferred format last. For fancy text, the sending user
587 agent should put the plainest format first and the richest format
588 last. Receiving user agents should pick and display the last format
589 they are capable of displaying. In the case where one of the
590 alternatives is itself of type "multipart" and contains unrecognized
591 sub-parts, the user agent may choose either to show that alternative,
592 an earlier alternative, or both.
