It is based on the idea that notes +should follow a predictable and descriptive file-naming scheme. The +file name must offer a clear indication of what the note is about, +without reference to any other metadata. Denote basically streamlines +the creation of such files. + +* The file-naming scheme +:PROPERTIES: +:CUSTOM_ID: h:4e9c7512-84dc-4dfb-9fa9-e15d51178e5d +:END: + +Every note produced by Denote follows this pattern: + +: DATE--KEYWORDS--TITLE.org + +The =DATE= field represents the date in year-month-day format followed +by an underscore and the current time in hour-minute-second notation. +The presentation is compact, with an underscore separating the two +components. Like this: =20220531_091625=. The =DATE= serves as the +unique identifier of each note. + +The =KEYWORDS= field consists of one or more entries demarcated by a +plus sign (the separator is inserted automatically). Each keyword is a +string provided by the user at the relevant prompt which broadly +describes the contents of the entry. Keywords that need to be more than +one-word-long must be written with an underscore. So when +=emacs_library= appears in a file name, it is interpreted as a single +keyword, whereas =emacs+library= are two distinct keywords. + +The =TITLE= field is the title of the note, as provided by the user, +that automatically gets downcased and hyphenated. An entry about +"Economics in the Euro Area" produces an =economics-in-the-euro-area= +string for the =TITLE= of the file name. + +Examples: + +: 20220107_124941--economics--plentiful-and-predictable-liquidity.org +: 20220214_104945--emacs+git--git-patch-formatting.org +: 20220420_113805--three_word_keyword--this-is-a-test.org + +While files end in the =.org= extension, the Denote code base does not +actually depend on org.el and/or its accoutrements. + +#+vindex: denote-directory +Notes are stored as a flat list in the ~denote-directory~ (i.e. no +subdirectories). The default path is =~/Documents/notes=. + +* Points of entry +:PROPERTIES: +:CUSTOM_ID: h:17896c8c-d97a-4faa-abf6-31df99746ca6 +:END: + +#+findex: denote +#+findex: denote-org-capture +There are two ways to write a note with Denote: invoke the ~denote~ +command or leverage the ~org-capture-templates~ by setting up a template +which calls the function ~denote-org-capture~. + +In the first case, all that is needed is to run ~denote~. It will first +prompt for a title. Once it is supplied, the command will ask for +keywords. The resulting note will have a file name as already explained +([[#h:4e9c7512-84dc-4dfb-9fa9-e15d51178e5d][The file naming scheme]]). + +#+vindex: denote-known-keywords +#+vindex: denote-infer-keywords +The keyword prompt supports minibuffer completion. Available candidates +are those defined in the user option ~denote-known-keywords~. More +candidates can be inferred from the names of existing notes, by setting +~denote-infer-keywords~ to non-nil (which is the case by default). + +Multiple keywords can be inserted by separating them with a comma (or +whatever the value of the ~crm-indicator~ is---which should be a comma). + +The ~denote~ command can also be called from Lisp, in which case it +expects the =TITLE= and =KEYWORDS= arguments, both of which are strings. + +For integration with ~org-capture~, the user must first add the relevant +template. Such as: + +#+begin_src emacs-lisp +(with-eval-after-load 'org-capture + (require 'denote-org-capture) + (add-to-list 'org-capture-templates + '("n" "New note (with Denote)" plain + (file denote-last-path) + #'denote-org-capture + :no-save t + :immediate-finish nil + :kill-buffer t + :jump-to-captured t))) +#+end_src + +[ In the future, we might develop Denote in ways which do not require such + manual intervation. ] + +Once the template is added, it is accessed from the specified key. If, +for instance, ~org-capture~ is bound to =C-c c=, then the note creation +is initiated with =C-c c n=. After that, the process is the same as +with invoking ~denote~ directly, namely: a prompt for a title followed +by a prompt for keywords. + +#+vindex: denote-org-capture-specifiers +Users may prefer to leverage ~org-capture~ in order to extend file +creation with the specifiers described in the ~org-capture-templates~ +documentation (such as to capture the active region and/or create a +hyperlink pointing to the given context). Due to the particular +file-naming scheme of Denote, such specifiers cannot be written directly +in the template. Instead, they have to be assigned to the user option +~denote-org-capture-specifiers~, which is interpreted by the function +~denote-org-capture~. Example with our default value: + +#+begin_src emacs-lisp +(setq denote-org-capture-specifiers "%l\n%i\n%?") +#+end_src + +* Linking notes +:PROPERTIES: +:CUSTOM_ID: h:fc913d54-26c8-4c41-be86-999839e8ad31 +:END: + +#+findex: denote-link +Denote has a basic linking facility to quickly establish connections +between notes. The command ~denote-link~ prompts for a file name in the +~denote-directory~ (only regular files are considered, not directories). +It then retrieves the path of the given note, inserts it at point using +the link notation of Org, and creates a backlink entry in the target +file. + +Backlinks are recorded at the end of a note under the heading with the +title =Denote backlinks=. Users should not edit this part manually: it +is controlled by Denote, such as to delete duplicate links (in the +future it might also handle stuff like alphabetic sorting). + +#+vindex: denote-link-insert-functions +#+findex: denote-link-backlink +The special hook ~denote-link-insert-functions~ is called after a link +is created. It accepts two arguments for the target file and the origin +of the current link. The function ~denote-link-backlink~ provides an +example for advanced users. + +#+findex: denote-link-clear-stale-backlinks +Backlinks that no longer point to available notes can be removed from +the current buffer with the command ~denote-link-clear-stale-backlinks~. + +* Fontification in Dired +:PROPERTIES: +:CUSTOM_ID: h:337f9cf0-9f66-45af-b73f-f6370472fb51 +:END: + +One of the upsides of Denote's file-naming scheme is the predictable +pattern it establishes, which appears as a near-tabular presentation in +a listing of notes (i.e. in Dired). The ~denote-dired-mode~ can help +enhance this impression, by fontifying the components of the file name +to make the date (identifier) and keywords stand out. + +#+begin_src emacs-lisp +(require 'denote-dired) +(add-hook 'dired-mode-hook #'denote-dired-mode) +#+end_src + +For the time being, the =diredfl= package is not compatible with this +facility. + +* Extending Denote +:PROPERTIES: +:CUSTOM_ID: h:8ed2bb6f-b5be-4711-82e9-8bee5bb06ece +:END: + +Denote is a tool with a narrow scope: create notes and link between +them, based on the aforementioned file-naming scheme. For other common +operations the user is advised to rely on standard Emacs facilities or +specialised third-party packages. + +- To search through notes, use =M-x grep=, =M-x find-name-dired=, =M-x + consult-find=, =M-x consult-grep=, and so on (the latter two are + provided by the =consult= package). + +- To quickly jump to the ~denote-directory~, visit it with =M-x + find-file= and then make a bookmark with =M-x bookmark-set=. Access + bookmarks with =M-x bookmark-jump=, =M-x consult-buffer= (from + =consult=), and the like. + +- Control the versioning of notes by turning the ~denote-directory~ into + a Git project. Consider the built-in project.el or the =projectile= + package, as well as the built-in VC framework and/or the =magit= + package. + +- It is possible to narrow the list of notes in Dired using a regular + expression or literal string. Do =M-x dired-mark-files-regexp RET + type-regexp-here RET t k=. The =t= will toggle the match so that it + marks all files that do not match the regexp and =k= will remove them + from the buffer (restore them by reverting the buffer). + +- A narrowed list of files can also be produced through the minibuffer, + with the help of the =embark= package. For example, =M-x find-file + RET path/to/denote-directory RET regexp embark-act embark-export=. + The final two commands, ~embark-act~ and ~embark-export~, are normally + bound to keys. The whole sequence will thus look like =C-x C-f path + RET regexp C-.

It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + + +1. APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The "Document", below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as "you". You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A "Modified Version" of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A "Secondary Section" is a named appendix or a front-matter section of +the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The "Invariant Sections" are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The "Cover Texts" are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A "Transparent" copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not "Transparent" is called "Opaque". + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, LaTeX input format, SGML +or XML using a publicly available DTD, and standard-conforming simple +HTML, PostScript or PDF designed for human modification. Examples of +transparent image formats include PNG, XCF and JPG. Opaque formats +include proprietary formats that can be read and edited only by +proprietary word processors, SGML or XML for which the DTD and/or +processing tools are not generally available, and the +machine-generated HTML, PostScript or PDF produced by some word +processors for output purposes only. + +The "Title Page" means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, "Title Page" means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +The "publisher" means any person or entity that distributes copies of +the Document to the public. + +A section "Entitled XYZ" means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as "Acknowledgements", +"Dedications", "Endorsements", or "History".) To "Preserve the Title" +of such a section when you modify the Document means that it remains a +section "Entitled XYZ" according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +2. VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no +other conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + + +3. COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to +give them a chance to provide you with an updated version of the +Document. + + +4. MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +A. Use in the Title Page (and on the covers, if any) a title distinct + from that of the Document, and from those of previous versions + (which should, if there were any, be listed in the History section + of the Document). You may use the same title as a previous version + if the original publisher of that version gives permission. +B. List on the Title Page, as authors, one or more persons or entities + responsible for authorship of the modifications in the Modified + Version, together with at least five of the principal authors of the + Document (all of its principal authors, if it has fewer than five), + unless they release you from this requirement. +C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. +D. Preserve all the copyright notices of the Document. +E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. +F. Include, immediately after the copyright notices, a license notice + giving the public permission to use the Modified Version under the + terms of this License, in the form shown in the Addendum below. +G. Preserve in that license notice the full lists of Invariant Sections + and required Cover Texts given in the Document's license notice. +H. Include an unaltered copy of this License. +I. Preserve the section Entitled "History", Preserve its Title, and add + to it an item stating at least the title, year, new authors, and + publisher of the Modified Version as given on the Title Page. If + there is no section Entitled "History" in the Document, create one + stating the title, year, authors, and publisher of the Document as + given on its Title Page, then add an item describing the Modified + Version as stated in the previous sentence. +J. Preserve the network location, if any, given in the Document for + public access to a Transparent copy of the Document, and likewise + the network locations given in the Document for previous versions + it was based on. These may be placed in the "History" section. + You may omit a network location for a work that was published at + least four years before the Document itself, or if the original + publisher of the version it refers to gives permission. +K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section all + the substance and tone of each of the contributor acknowledgements + and/or dedications given therein. +L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section titles. +M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. +N. Do not retitle any existing section to be Entitled "Endorsements" + or to conflict in title with any Invariant Section. +O. Preserve any Warranty Disclaimers. + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled "Endorsements", provided it contains +nothing but endorsements of your Modified Version by various +parties--for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + + +5. COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled "History" +in the various original documents, forming one section Entitled +"History"; likewise combine any sections Entitled "Acknowledgements", +and any sections Entitled "Dedications". You must delete all sections +Entitled "Endorsements". + + +6. COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other +documents released under this License, and replace the individual +copies of this License in the various documents with a single copy +that is included in the collection, provided that you follow the rules +of this License for verbatim copying of each of the documents in all +other respects. + +You may extract a single document from such a collection, and +distribute it individually under this License, provided you insert a +copy of this License into the extracted document, and follow this +License in all other respects regarding verbatim copying of that +document. + + +7. AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an "aggregate" if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + + +8. TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled "Acknowledgements", +"Dedications", or "History", the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + + +9. TERMINATION + +You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. + + +10. FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions of the +GNU Free Documentation License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in +detail to address new problems or concerns. See +https://www.gnu.org/licenses/. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License "or any later version" applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. If the Document +specifies that a proxy can decide which future versions of this +License can be used, that proxy's public statement of acceptance of a +version permanently authorizes you to choose that version for the +Document. + +11. RELICENSING + +"Massive Multiauthor Collaboration Site" (or "MMC Site") means any +World Wide Web server that publishes copyrightable works and also +provides prominent facilities for anybody to edit those works. A +public wiki that anybody can edit is an example of such a server. A +"Massive Multiauthor Collaboration" (or "MMC") contained in the site +means any set of copyrightable works thus published on the MMC site. + +"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 +license published by Creative Commons Corporation, a not-for-profit +corporation with a principal place of business in San Francisco, +California, as well as future copyleft versions of that license +published by that same organization. + +"Incorporate" means to publish or republish a Document, in whole or in +part, as part of another Document. + +An MMC is "eligible for relicensing" if it is licensed under this +License, and if all works that were first published under this License +somewhere other than this MMC, and subsequently incorporated in whole or +in part into the MMC, (1) had no cover texts or invariant sections, and +(2) were thus incorporated prior to November 1, 2008. + +The operator of an MMC Site may republish an MMC contained in the site +under CC-BY-SA on the same site at any time before August 1, 2009, +provided the MMC is eligible for relicensing. + + +ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + + Copyright (c) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. + A copy of the license is included in the section entitled "GNU + Free Documentation License". + +If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, +replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with the + Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. + +If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + +If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of +free software license, such as the GNU General Public License, +to permit their use in free software. +</pre> +#+end_export + +#+html: <!-- + +* Indices +:PROPERTIES: +:CUSTOM_ID: h:dd530040-de9d-4f2b-8dfd-d8b8f14c058e +:END: + +** Function index +:PROPERTIES: +:INDEX: fn +:CUSTOM_ID: h:317b8c20-6dc1-4390-a20a-d01d75a48ccb +:END: + +** Variable index +:PROPERTIES: +:INDEX: vr +:CUSTOM_ID: h:2f69d4fe-0804-4f7f-aa57-4e03e7f20d98 +:END: + +** Concept index +:PROPERTIES: +:INDEX: cp +:CUSTOM_ID: h:10365e44-2fc0-4b66-a613-682fea09ee68 +:END: + +#+html: -->
