list2card

A simple program to summarise the cards on a Trello list as a comment on a card, then archive the cards on the source list.

Purpose

At the end of every week I summarise the "Done" column of my personal Trello board into a "Captain's Log" metacard, before archiving all of the completed tasks. I wrote list2card to automate this process.

Note: scheduling the execution of list2card is left as an exercise for the reader.

Installation

$ gem install trello-list2card

Configuration

list2card requires a configuration file to operate. An example is available on Github, or you can follow the guide below.

Trello API key and token

Visit https://trello.com/app-key to get your unique API key and token.

Config file:

$ cat config.toml
user_key   = '<KEY>'
user_token = '<TOKEN>'

Source list, destination card

First list your boards to find the id of board you want to work with

$ list2card --list-boards
 *  id                       name                                       url
[*] abc123abc123abc123abc123 Test board A                               https://trello.com/b/abc123ab/test-board-a
[ ] 123abc123abc123abc123abc Test board B                               https://trello.com/b/123abc12/test-board-b

Now list the lists on the board to find your source_list_id

$ list2card --list-lists abc123abc123abc123abc123
id                       name
xyz789zxy789xyz789xyz789 Todo
789xyz789xyz789xyz789xyz Done

Finally list the cards on the appropriate list to find the id of your summary metacard dest_card_id

$ list2card --list-cards xyz789zxy789xyz789xyz789
id                       name                                       url
def456def456def456def456 Captain's Log                              https://trello.com/c/aabbccdd

Final config file

$ cat config.toml
user_key   = '<KEY>'
user_token = '<TOKEN>'

source_list_id = '789xyz789xyz789xyz789xyz'
dest_card_id   = 'def456def456def456def456'

Usage

$ list2card -c config.toml

This will silently summarise the contents of source_list_id into dest_card_id as a comment in the following format:

N tasks completed
<Task 1>
<Task ..>
<Task N>

Before archiving the cards on source_list_id.

Note: No entry will be written if there are no cards to summarise.

Logging

Log level can be adjusted with -l [debug,info,warn,error,fatal] (defaults to warn).

Dry-run

Dry-run (read-only, don't write comment or archive cards) can be enabled with -d. Note: you'll probably want to increase the log level with -l for this to be useful.

Exit codes

Code	Meaning
0	Success (wrote output, or nothing to do)
1	Failure. Something went wrong. Always accompanied by a FATAL log message.
