### Introduction

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

[bukuserver](https://github.com/jarun/Buku/tree/master/bukuserver) exposes a browsable front-end on a local web host server.

`buku` can auto-import bookmarks from your browser(s) or fetch the title and description of a bookmarked url from the web. 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. `buku` can look up the latest snapshot of a broken link on the Wayback Machine. There's an Easter egg to revisit random forgotten bookmarks too! *Buku* is too busy to track you: no hidden history, obsolete records, usage analytics or homing.

To get started right away, jump to the [Quickstart](#quickstart) section. We have one of the best documentation around. You'll find handy examples in the man page too. For more details, 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.

### Installation

#### Dependencies

| Feature | Dependency |
| --- | --- |
| Scripting language | Python 3.4+ |
| HTTPS | certifi, urllib3 |
| Encryption | cryptography |
| HTML | beautifulsoup4, html5lib |

To install package dependencies using pip3, run:

    # pip3 install certifi urllib3 cryptography beautifulsoup4
or on Ubuntu:

    # apt-get install ca-certificates python3-urllib3 python3-cryptography python3-bs4

To copy url to clipboard at the prompt `Buku` uses `xsel` (or `xclip`) on Linux, `pbcopy` (default installed) on OS X, `clip` (default installed) on Windows, `termux-clipboard` on Termux (terminal emulation for Android). If X11 is missing, GNU Screen or tmux copy-paste buffers are recognized.

#### 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.

### Quickstart

1. Export `VISUAL` or `EDITOR` to point to your favourite editor. Note that `VISUAL` takes precedence over `EDITOR`.
2. Create a sweeter shortcut with some convenience.

       alias b='buku --suggest'
3. Auto-import bookmarks from your browser(s). Please quit the relevant browsers beforehand to ensure the databases are not locked.

       b --ai
4. Manually add a bookmark (for hands-on).

       b -w
5. List your bookmarks with DB index.

       b -p
6. For GUI and browser 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).

### 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, Markdown, Orgfile or a new database:

       $ buku -e bookmarks.html --stag tag 1, tag 2
       $ buku -e bookmarks.md --stag tag 1, tag 2
       $ buku -e bookmarks.org --stag tag 1, tag 2
       $ buku -e bookmarks.db --stag tag 1, tag 2
    All bookmarks are exported if search is not opted.
10. **Import** bookmarks from HTML, Markdown or Orgfile:

        $ buku -i bookmarks.html
        $ buku -i bookmarks.md
        $ buku -i bookmarks.org
        $ 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 can update the title or description fields of non-immutable bookmarks by parsing the fetched page. Fields are updated only if the fetched fields are non-empty. Tags remain untouched.
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 any of the keywords `hello` or `world`, excluding the keywords `real` and `life`, matching both the tags `kernel` and `debugging`, but **excluding** the tags `general kernel concepts` and `books`:

        $ buku hello world --exclude real life --stag 'kernel + debugging - general kernel concepts, books'
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**:

### Automation

Interactive workflows can be automated using expect. Issue [#368](https://github.com/jarun/Buku/issues/368) has a working example on automating auto-import.

### Troubleshooting

#### Editor integration

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.
