The tool aims to let you search and navigate through DEVONthink effectively. It learns from your habit so that the items get hitted most will show at the top.

Just enter the keyword and it will do a live and prefix search then nicely present the results for you.

It is a pitty that we cannot create direct entries for DEVONthink items in LaunchBar. We have to first open this action then search then select one... What if we can create a shortcut for the item and make it accessible directly from LaunchBar without using this tool.

Well, you can! Just press ⌘ + ⌥ + ↵ on that item.

Next time that item will be searchable directly from LaunchBar by its name.

You can later assign an abbreviation for it to access it faster.

Make sure ~/Documents/ is in the index of you LaunchBar otherwise it would not work. See here for more details.

This tool requires Python3 to be installed at the path /usr/bin/python3. If you are using macOS Catalina or higher version, you can run this command in terminal

xcode-select --install

to install Python3.

See https://installpython3.com/mac/ for more details.

If you use homebrew or other ways to install Python3, make sure it is accessible via /usr/bin/python3.

It can be downloaded here.

If it is not a group:

• ⌘ + ⌥ + ↵ to create shortcut for that item.
• ⌘ + ↵ to reveal that item in DEVONthink
• ⇧ + ↵ to reveal that item in Finder
• ⌥ + ↵ to open that item externally

If it is a group:

• ⌘ + ⌥ + ↵ to create shortcut for that item.
• ⌘ + ↵ to reveal that item in DEVONthink
• ⌥ + ↵ to navigate through that group in Launchbar

Note that if you are already in "navigation mode" (when you have pressed ⌥ + ↵ on a group), just press ↵ and you can continue navigate, press ⌥ + ↵ will instead open that group in DEVONthink.

If you tag a file/group exclude-from-launchbar, it will not be shown in the result.

You can adjust all those values in the config file config.py.

config.py file:

# Do not change this class
class DefaultConfig:
    a = 0.8
    b = 0.5
    frequency_weight = 2
    excluded_tag = 'exclude-from-launchbar'
    max_result_num = 80 # Set to None to cancel the limit. Note that this may cause performance issue!
    shortcut_path = '~/Documents/DEVONthink' # Set to None to disable shortcut creation


# change this one
class UserConfig(DefaultConfig):
    a = 0.8
    b = 0.5
    frequency_weight = 2
    excluded_tag = 'exclude-from-launchbar'
    max_result_num = 80
    shortcut_path = '~/Documents/DEVONthink'

Do not change the DefaultConfig class. Instead change the properties of UserConfig.

The max_result_num option can be set to None so that all the results will be presented in LaunchBar. Note that too many results may cause performance issue!

As you may notice, the so-called shortcut is just a inetloc file created in your filesystem with the name and item link of the corresponding DEVONthink item. The default creation path is set to be ~/Documents/DEVONthink. You can change it to any other locations that you have write permission to, and make sure it is in your LaunchBar's index list. Set it to None will prevent the creation of any "shortcuts".

Except for the search score given by DEVONthink, the tool will adjust that score based on the frequency you open items.

final_score = search_score + weight * frequency_score

How do the tool calcuate the frequency_score?

Every time you choose a item, it update the frequency score of every item appears using the following formula.

frequency_score = old_score * a + (1 - a) * (1 if is_chosen else 0)

The initial value is 0. The frequency_score is set to b (in config.py) the first time it is selected. Later if it is not selected, the score will decrease according the the formula. But it will not drop below b.

The query template used is name:({}) tags!={}. So only the name is searched and the specific tag is excluded (default to exclude-from-launchbar). In more detail, each keyword entered is prepended with a ~. For example, if the text you type in LaunchBar is hello world, then the actual query will be name:(~hello ~world) tags!=exclude-from-launchbar.
