Buku

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.

Though a terminal utility, it's possible to add bookmarks to buku without touching the terminal! Refer to the section on GUI integration. If you prefer the terminal, thanks to the shell completion scripts, you don't need to memorize any of the options. There's an Easter egg to revisit random forgotten bookmarks too.

Buku is too busy to track you - no history, obsolete records, usage analytics or homing.

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

PRs are welcome. Please visit #135 for a list of TODOs.

Operational notes

The database file is stored in:
- $XDG_DATA_HOME/buku/bookmarks.db, if XDG_DATA_HOME is defined (first preference) or
- $HOME/.local/share/buku/bookmarks.db, if HOME is defined (second preference) or
- %APPDATA%\buku\bookmarks.db, if you are on Windows or
- the current directory.
If the URL contains characters like ;, & or brackets they may be interpreted specially by the shell. To avoid it, add the URL within single or double quotes ('/").
URLs are unique in DB. The same URL cannot be added twice.
Bookmarks with immutable titles are listed with (L) after the title.
Tags:
- Comma (,) is the tag delimiter in DB. A tag cannot have comma(s) in it. Tags are filtered (for unique tags) and sorted. Tags are stored in lower case and can be replaced, appended or deleted.
- Folder names are converted to all-lowercase tags during bookmarks html import.
- Releases prior to v2.7 support both capital and lower cases in tags. From v2.7 all tags are stored in lowercase. An undocumented option --fixtags is introduced to modify the older tags. It also fixes another issue where the same tag appears multiple times in the tagset of a record. Run buku --fixtags once.
- Tags can be edited from the prompt very easily using >> (append), > (overwrite) and << (remove) symbols. The LHS of the operands denotes the indices and ranges of tags to apply (as listed by --tag or key t at prompt) and the RHS denotes the actual DB indices and ranges of the bookmarks to apply the change to.
Update operation:
- If --title, --tag or --comment is passed without argument, clear the corresponding field from DB.
- If --url is passed (and --title is omitted), update the title from web using the URL.
- If indices are passed without any other options (--url, --title, --tag, --comment and --immutable), read the URLs from DB and update titles from web. Bookmarks marked immutable are skipped.
- Can update bookmarks matching a search, when combined with any of the search options and no arguments to update are passed.
Delete operation:
- When a record is deleted, the last record is moved to the index.
- Delete doesn't work with range and indices provided together as arguments. It's an intentional decision to avoid extra sorting, in-range checks and to keep the auto-DB compaction functionality intact. On the same lines, indices are deleted in descending order.
- Can delete bookmarks matching a search, when combined with any of the search options and no arguments to delete are passed.
Search works in mysterious ways:
- Case-insensitive.
- Matches words in URL, title and tags.
- --sany : match any of the keywords in URL, title or tags. Default search option.
- --sall : match all the keywords in URL, title or tags.
- --deep : match substrings (match matches rematched) in URL, title and tags.
- --sreg : match a regular expression (ignores --deep).
- --stag : search bookmarks by a tag, or list all tags alphabetically with usage count (if no arguments).
- Search results are indexed serially. This index is different from actual database index of a bookmark record which is shown within [] after the title.
Encryption is optional and manual. AES256 algorithm is used. To use encryption, the database file should be unlocked (-k) before using buku and locked (-l) afterwards. Between these 2 operations, the database file lies unencrypted on the disk, and NOT in memory. Also, note that the database file is unencrypted on creation.
Editor support:
- A single bookmark can be edited before adding. The editor can be set using the environment variable EDITOR or by explicitly specifying the editor. The latter takes preference. If -a is used along with -w, the details are populated in the editor template.
- In case of edit and update (a single bookmark), the existing record details are fetched from DB and populated in the editor template. The environment variable EDITOR must be set Note that -u works independently of -w.
- All lines beginning with "#" will be stripped. Then line 1 will be treated as the URL, line 2 will be the title, line 3 will be comma separated tags, and the rest of the lines will be parsed as descriptions.
Proxy support: environment variable https_proxy, if defined, is used to tunnel data for both http and https connections. The supported format is:
```
http[s]://[username:password@]proxyhost:proxyport/
```

GUI integration

buku can be integrated in a GUI environment with simple tweaks.

Add bookmarks from anywhere

With support for piped input, it's possible to add bookmarks to buku using keyboard shortcuts on Linux and OS X. CLIPBOARD (plus PRIMARY on Linux) text selections can be added directly this way. The additional utility required is xsel (on Linux) or pbpaste (on OS X).

The following steps explore the procedure on Linux with Ubuntu as the reference platform.

To install xsel on Ubuntu, run:
```
 $ sudo apt install xsel
```
Create a new script bukuadd with the following content:
```
 #!/bin/bash

 xsel | buku -a
```
-a is the option to add a bookmark.
Make the script executable:
```
 $ chmod +x bukuadd
```
Copy it somewhere in your PATH.
Add a new keyboard shortcut to run the script. I use <Alt-b>.

Test drive

Copy or select a URL with mouse and press the keyboard shortcut to add it to the buku database. The addition might take a few seconds to reflect depending on your internet speed and the time buku needs to fetch the title from the URL. To avoid title fetch from the web, add the --title option to the script.

To verify that the bookmark has indeed been added, run:

$ buku -p -1

and check the entry.

Tips

To add the last visited URL in Firefox to buku, use the following script:

  #!/bin/bash

  sqlite3 $HOME/.mozilla/firefox/*.default/places.sqlite "select url from moz_places where last_visit_date=(select max(last_visit_date) from moz_places)" | buku -a

If you want to tag these bookmarks, look them up later using:
```
  $ buku -S blank
```
Use option -u to tag these bookmarks.

Import bookmarks to browser

buku can export (or import) bookmarks in HTML format recognized by Firefox, Google Chrome and Internet Explorer.

To export all bookmarks, run:

$ buku --export path_to_bookmarks.html

To export specific tags, run:

$ buku --export path_to_bookmarks.html --tag tag 1, tag 2

Once exported, import the html file in your browser.

Sync database across systems

buku has the capability to import records from another buku database file. However, users with a cloud service client installed on multiple systems can keep the database synced across these systems automatically. To achieve this store the actual database file in a synced directory and create a symbolic link to it in the location where the database file would exist otherwise. For example, $HOME/.local/share/buku/bookmarks.db can be a symbolic link to ~/synced_dir/bookmarks.db.

As a library

buku is developed as a powerful python library for bookmark management. All functionality are available through carefully designed APIs. main() is a good usage example. It's also possible to use a custom database file in multi-user scenarios. Check out the documentation for the following APIs which accept an optional argument as database file:

BukuDb.initdb(dbfile=None)
BukuCrypt.encrypt_file(iterations, dbfile=None)
BukuCrypt.decrypt_file(iterations, dbfile=None)

NOTE: This flexibility is not exposed in the program.

The api directory has several example wrapper web APIs, not necessarily updated. Feel free to update if you need them.

An example to print the http status code of urls saved in buku goes below. To run, install grequests.

import buku
import grequests

bdb = buku.BukuDb()
recs = bdb.get_rec_all()
recs[0]
# output: (1, 'example.com', 'example', 'tag1,tag2', 'page description', 0)
# Records have following structure:
# - id,
# - url,
# - metadata,
# - tags,
# - description,
# - flags
urls = [x[1] for x in recs]
rs = (grequests.get(u) for u in urls)
gr_results = grequests.map(rs)
for resp, url in zip(gr_results, urls):
  stat_code = None if resp.status_code is None else resp.status_code
  print('{}: {}'.format(stat_code, url))
# output
# 200: http://example.com
# None: http://website1.com/
# 200: http://website2.com/
# ...

Examples

Edit and add a bookmark from editor:
```
 $ buku -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 will open 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 and markdown:
```
 $ buku -e bookmarks.html --tag tag 1, tag 2

```
This operation does not modify the indexes, URLs, tags or comments. Only title is refreshed if fetched title is non-empty.
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.

// 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

More help:
```
$ buku -h
$ man buku
```

Third-party integration

buku waits until its input is closed when not started in a tty. For example, the following hangs:
```
 $ cat | buku
```
This is the intended behaviour as the primary reason behind supporting piped input is to add bookmarks with a keyboard shortcut. Third-party applications should explicitly close the input stream or use a wrapper script like the following one:
```
 #!/bin/bash

 echo $1 | buku -a
```
