### Introduction

`buku` is a powerful bookmark manager written in Python3 and SQLite3. When I started writing it, I couldn't find a flexible cmdline solution with a private, portable, merge-able database along with browser integration. Hence, `Buku` (after my son's nickname, meaning *close to the heart* in my language).

`buku` fetches the title of a bookmarked web page and stores it along with any additional comments and tags. You can use your favourite editor to compose and update bookmarks. With multiple search options, including regex and a deep scan mode (particularly for URLs), it can find any bookmark instantly. Multiple search results can be opened in the browser at once.

For GUI integration (or to sync bookmarks with your favourite bookmark management service), refer to the wiki page on [System integration](https://github.com/jarun/Buku/wiki/System-integration). If you prefer the terminal, thanks to the [shell completion](#shell-completion) scripts, you don't need to memorize any of the options. There's an Easter egg to revisit random forgotten bookmarks too.

We have one of the best documentation around. You can start with the [Examples](#examples). *Buku* is too busy to track you - no hidden history, obsolete records, usage analytics or homing. To learn more on how it works or to contribute to the project, please refer to the wiki page on [Operational notes](https://github.com/jarun/Buku/wiki/Operational-notes).

There are several [projects based on `buku`](#related-projects), including a browser plug-in.

PRs are welcome. Please visit [#233](https://github.com/jarun/Buku/issues/233) for a list of TODOs. Visit the [wiki](https://github.com/jarun/Buku/wiki) for guidelines.

#### Colors

`buku` supports custom colors. Visit the wiki page on how to [customize colors](https://github.com/jarun/Buku/wiki/Customize-colors) for more details.

### Examples

1. **Edit and add** a bookmark from editor:

       $ buku -w
       $ buku -w 'gedit -w'
       $ buku -w 'macvim -f' -a https://ddg.gg search engine, privacy
    The first command picks editor from the environment variable `EDITOR`. The second command opens gedit in blocking mode. The third command opens macvim with option -f and the URL and tags populated in template.
2. **Add** a bookmark with **tags** `search engine` and `privacy`, **comment** `Search engine with perks`, **fetch page title** from the web:

       $ buku -a https://ddg.gg search engine, privacy -c Search engine with perks
       336. DuckDuckGo
       > https://ddg.gg
       + Alternative search engine with perks
       # privacy,search engine
    where, >: url, +: comment, #: tags
3. **Add** a bookmark with tags `search engine` & `privacy` and **immutable custom title** `DDG`:

       $ buku -a https://ddg.gg search engine, privacy --title 'DDG' --immutable 1
       336. DDG (L)
       > https://ddg.gg
       # privacy,search engine
    Note that URL must precede tags.
4. **Add** a bookmark **without a title** (works for update too):

       $ buku -a https://ddg.gg search engine, privacy --title
5. **Edit and update** a bookmark from editor:

       $ buku -w 15012014
    This will open the existing bookmark's details in the editor for modifications. Environment variable `EDITOR` must be set.
6. **Update** existing bookmark at index 15012014 with new URL, tags and comments, fetch title from the web:

       $ buku -u 15012014 --url http://ddg.gg/ --tag web search, utilities -c Private search engine
7. **Fetch and update only title** for bookmark at 15012014:

       $ buku -u 15012014
8. **Update only comment** for bookmark at 15012014:

       $ buku -u 15012014 -c this is a new comment
    Applies to --url, --title and --tag too.
9. **Export** bookmarks tagged `tag 1` or `tag 2` to HTML and markdown:

       $ buku -e bookmarks.html --tag tag 1, tag 2
       $ buku -e bookmarks.md --tag tag 1, tag 2
       $ buku -e bookmarks.db --tag tag 1, tag 2
    All bookmarks are exported if --tag is not specified.
10. **Import** bookmarks from HTML and markdown:

        $ buku -i bookmarks.html
        $ buku -i bookmarks.md
        $ buku -i bookmarks.db
11. **Delete only comment** for bookmark at 15012014:

        $ buku -u 15012014 -c
    Applies to --title and --tag too. URL cannot be deleted without deleting the bookmark.
12. **Update** or refresh **full DB** with page titles from the web:

        $ buku -u
        $ buku -u --tacit (show only failures and exceptions)
    This operation does not modify the indexes, URLs, tags or comments. Only title is refreshed if fetched title is non-empty.
13. **Delete** bookmark at index 15012014:

        $ buku -d 15012014
        Index 15012020 moved to 15012014
    The last index is moved to the deleted index to keep the DB compact.
14. **Delete all** bookmarks:

        $ buku -d
15. **Delete** a **range or list** of bookmarks:

        $ buku -d 100-200
        $ buku -d 100 15 200
16. **Search** bookmarks for **ANY** of the keywords `kernel` and `debugging` in URL, title or tags:

        $ buku kernel debugging
        $ buku -s kernel debugging
17. **Search** bookmarks with **ALL** the keywords `kernel` and `debugging` in URL, title or tags:

        $ buku -S kernel debugging
18. **Search** bookmarks **tagged** `general kernel concepts`:

        $ buku --stag general kernel concepts
19. **Search** for bookmarks matching **ANY** of the tags `kernel`, `debugging`, `general kernel concepts`:

        $ buku --stag kernel, debugging, general kernel concepts
20. **Search** for bookmarks matching **ALL** of the tags `kernel`, `debugging`, `general kernel concepts`:

        $ buku --stag kernel + debugging + general kernel concepts
21. **Search** for bookmarks matching both the tags `kernel` and `debugging`, but **excluding** bookmarks matching the tag `general kernel concepts`:

        $ buku --stag kernel + debugging - general kernel concepts
22. List **all unique tags** alphabetically:

        $ buku --stag
23. Run a **search and update** the results:

        $ buku -s kernel debugging -u --tag + linux kernel
24. Run a **search and delete** the results:

        $ buku -s kernel debugging -d
25. **Encrypt or decrypt** DB with **custom number of iterations** (15) to generate key:

        $ buku -l 15
        $ buku -k 15
    The same number of iterations must be specified for one lock & unlock instance. Default is 8, if omitted.
26. **Show details** of bookmarks at index 15012014 and ranges 20-30, 40-50:

        $ buku -p 20-30 15012014 40-50
27. Show details of the **last 10 bookmarks**:

        $ buku -p -10
28. **Show all** bookmarks with real index from database:

        $ buku -p
        $ buku -p | more
29. **Replace tag** 'old tag' with 'new tag':

        $ buku --replace 'old tag' 'new tag'
30. **Delete tag** 'old tag' from DB:

        $ buku --replace 'old tag'
31. **Append (or delete) tags** 'tag 1', 'tag 2' to (or from) existing tags of bookmark at index 15012014:

        $ buku -u 15012014 --tag + tag 1, tag 2
        $ buku -u 15012014 --tag - tag 1, tag 2
32. **Open URL** at index 15012014 in browser:

        $ buku -o 15012014
33. List bookmarks with **no title or tags** for bookkeeping:

        $ buku -S blank
34. List bookmarks with **immutable title**:

        $ buku -S immutable
35. **Shorten URL** www.google.com and the URL at index 20:

        $ buku --shorten www.google.com
        $ buku --shorten 20
36. **Append, remove tags at prompt** (taglist index to the left, bookmark index to the right):

        // append tags at taglist indices 4 and 6-9 to existing tags in bookmarks at indices 5 and 2-3
        buku (? for help) g 4 9-6 >> 5 3-2
        // set tags at taglist indices 4 and 6-9 as tags in bookmarks at indices 5 and 2-3
        buku (? for help) g 4 9-6 > 5 3-2
        // remove all tags from bookmarks at indices 5 and 2-3
        buku (? for help) g > 5 3-2
        // remove tags at taglist indices 4 and 6-9 from tags in bookmarks at indices 5 and 2-3
        buku (? for help) g 4 9-6 << 5 3-2
37. List bookmarks with **colored output**:

        $ buku --colors oKlxm -p
38. More **help**:

        $ buku -h
        $ man buku

You may encounter issues with GUI editors which maintain only one instance by default and return immediately from other instances. Use the appropriate editor option to block the caller when a new document is opened. See issue [#210](https://github.com/jarun/Buku/issues/210) for gedit.
