buku

buku in action!

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 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 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.

There are several projects based on buku, including a browser plug-in.

Installation

Dependencies

Feature	Dependency
Scripting language	Python 3.6+
HTTPS	certifi, urllib3
Encryption	cryptography
HTML	beautifulsoup4, html5lib

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.

From a package manager

To install buku with all its dependencies from PyPI, run:

# pip3 install buku

You can also install buku from your package manager. If the version available is dated try an alternative installation method.

Packaging status (expand)

Unlisted packagers:

● PyPI (pip3 install buku)
● Termux (pip3 install buku)

Release packages

Auto-generated packages (with only the cli component) for Arch Linux, CentOS, Debian, Fedora, openSUSE Leap and Ubuntu are available with the latest stable release.

NOTE: CentOS may not have the python3-beautifulsoup4 package in the repos. Install it using pip3.

From source

If you have git installed, clone this repository. Otherwise download the latest stable release or development version (risky).

Install the dependencies. For example, on Ubuntu:

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

Install the cli component to default location (/usr/local):

$ sudo make install

To remove, run:

$ sudo make uninstall

PREFIX is supported, in case you want to install to a different location.

Running standalone

buku is a standalone utility. From the containing directory, run:

$ chmod +x buku
$ ./buku

Shell completion

Shell completion scripts for Bash, Fish and Zsh can be found in respective subdirectories of auto-completion/. Please refer to your shell's manual for installation instructions.

Colors

buku supports custom colors. Visit the wiki page on how to customize colors for more details.

Quickstart

Export VISUAL or EDITOR to point to your favourite editor. Note that VISUAL takes precedence over EDITOR.
Create a sweeter shortcut with some convenience.
```
alias b='buku --suggest'
```
Auto-import bookmarks from your browser(s). Please quit the relevant browsers beforehand to ensure the databases are not locked.
```
b --ai
```
Manually add a bookmark (for hands-on).
```
b -w
```
List your bookmarks with DB index.
```
b -p
```
For GUI and browser integration (or to sync bookmarks with your favourite bookmark management service) refer to the wiki page on System integration.
Handy (bash/zsh) command to fuzzy search all URLs and open the selected one in Firefox:
```
firefox $(buku -p -f 10 | fzf)
```

Examples

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.

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

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.

Add a bookmark without a title (works for update too):

$ buku -a https://ddg.gg search engine, privacy --title

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.
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
```
Fetch and update only title for bookmark at 15012014:
```
$ buku -u 15012014
```
Update only comment for bookmark at 15012014:
```
$ buku -u 15012014 -c this is a new comment
```
Applies to --url, --title and --tag too.

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.

Import bookmarks from HTML, Markdown or Orgfile:

$ buku -i bookmarks.html
$ buku -i bookmarks.md
$ buku -i bookmarks.org
$ buku -i bookmarks.db

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.
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.
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. Add --tacit to delete without confirmation.
Delete all bookmarks:
```
$ buku -d
```
Delete a range or list of bookmarks:
```
$ buku -d 100-200
$ buku -d 100 15 200
```
Search bookmarks for ANY of the keywords kernel and debugging in URL, title or tags:
```
$ buku kernel debugging
$ buku -s kernel debugging
```
Search bookmarks with ALL the keywords kernel and debugging in URL, title or tags:
```
$ buku -S kernel debugging
```
Search bookmarks tagged general kernel concepts:
```
$ buku --stag general kernel concepts
```
Search for bookmarks matching ANY of the tags kernel, debugging, general kernel concepts:
```
$ buku --stag kernel, debugging, general kernel concepts
```
Search for bookmarks matching ALL of the tags kernel, debugging, general kernel concepts:
```
$ buku --stag kernel + debugging + general kernel concepts
```
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'
```
List all unique tags alphabetically:
```
$ buku --stag
```

Run a search and update the results:

$ buku -s kernel debugging -u --tag + linux kernel

Run a search and delete the results:
```
$ buku -s kernel debugging -d
```
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.
Show details of bookmarks at index 15012014 and ranges 20-30, 40-50:
```
$ buku -p 20-30 15012014 40-50
```
Show details of the last 10 bookmarks:
```
$ buku -p -10
```
Show all bookmarks with real index from database:
```
$ buku -p
$ buku -p | more
```
Replace tag 'old tag' with 'new tag':
```
$ buku --replace 'old tag' 'new tag'
```
Delete tag 'old tag' from DB:
```
$ buku --replace 'old tag'
```
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
```
Open URL at index 15012014 in browser:
```
$ buku -o 15012014
```
List bookmarks with no title or tags for bookkeeping:
```
$ buku -S blank
```
List bookmarks with immutable title:
```
$ buku -S immutable
```

Shorten URL www.google.com and the URL at index 20:

$ buku --shorten www.google.com
$ buku --shorten 20

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

List bookmarks with colored output:
```
$ buku --colors oKlxm -p
```
More help:
```
$ buku -h
$ man buku
```

Automation

Interactive workflows can be automated using expect. Issue #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 for gedit.
