Build Status

tld is a tool for people who want to do things, but who might also want a bit of flexibility.

tld (pronounced "told", based off of Steve Losh's t.py but with a LD twist) is a simple command line tool that works like a (somewhat) minimal list manager. Calling

$ python tld.py This is a message.

will create a file called tasks in the current directory and put "This is a message." (and some identifier) in that file. Calling it again will print the contents of the file.

$ python tld.py
3 - This is a message.

The 3 at the start of the output is an identifier, and can be referenced. Calling

$ python tld.py -f 3

will mark this message as "done" and move it to a file .tasks.done in the current directory.

For more options, call

$ python tld.py -h

or see the options description on the github page https://github.com/davidlowryduda/tld.

Why use tld?

Steve Losh designed t.py to do the simplest thing that could possibly work: you can add, edit, remove, and finish elements from a list. It's simple, messy, and has almost no features to distract you from getting in the way of doing things. It's easy to say "I'll just organize my list a bit" and spend 15 minutes tagging, coloring, setting priorities, and so forth.

And if that works for you, great! Then t.py is enough.

tld does everything t.py does, except with a few more features (and a bit less purity). In particular, tld supports simple date annotations, simple tagging, and philosophically isn't against complete organization.

Where t.py encourages you to use different aliases to different tasklists for different one level of organization, tld allows one to use tags in fewer lists.

It's Flexible

Do you want to edit a bunch of items at once? Open the list in a text editor, and tld will handle the rest.

Do you want to view the list on a computer that doesn't have tld installed? Open the list in a text editor.

Do you want to synchronize your list across multiple computers? Keep your lists in a Dropbox folder or a github repository.

It Plays Nice with Version Control

tld follows the lead of other systems which keep lists in a plain text file. This is a great idea.

tld also follows t.py's use of random IDs to order the items in the list. When list managers append new items to the end of the list and multiple users edit a list, then merge conflicts will occur and require manual handling.

If order really matters, then this makes sense. But if order really matters, then you shouldn't be using tld.

tld uses random IDs (actually SHA1 hashes) to order the list. Once a list has a couple of items in it, adding more is far less likely to cause merge conflicts.

Installing tld

tld requires Python 3.6+ and a bash-like shell. It works on Linux, OS X, and Windows (with the linux subsystem).

Installing and setting up tld will take about one minute.

First, download the newest version or clone the github repository (git clone https://github.com/davidlowryduda/tld).

You can also use pip through a command like

python3 -m pip install --user --upgrade tld-task

If you use pip, then you can replace 'python3 ~/path/to/tld.pywithtld` in the examples below.

Next, decide where you want to keep your lists. I put mine in ~/notes/tasks (I keep notes created from other note utilities in ~/notes/ too). Create that directory (or whatever directory you plan on using).

mkdir -p ~/notes/tasks

Set up an alias to run tld. Put something like this in your ~/.bashrc file:

alias tld='python3 ~/path/to/tld.py --task-dir ~/notes/tasks --list tasks'

Make sure you run source ~/.bashrc or restart your terminal window to make the alias take effect. Now tld is ready to use.

Using tld

tld is quick and easy to use, especially when used in combination with other tools. Commandline usage is available through tld -h or tld --help, and is a good reference once you grok the workflow.

Add an Item

To add an item, use tld [item description]:

$ tld Tell my wife I love her.
$ tld Prove the Riemann Hypothesis.
$ tld "Read Steve Losh's .vimrc."

List Your Items

Listing your items is even easier -- just use tld:

$ tld
1 - Read Steve Losh's .vimrc.
a - Tell my wife I love her.
b - Prove the Riemann Hypothesis.

tld will list all of your unfinished items and their IDs. Do you not want to see the IDs? Use the "quiet" option by using tld -q or tld --quiet.

Finish an Item

After you're done with something, use tld -f ID to finish it:

$ tld -f b
$ tld
1 - Read Steve Losh's .vimrc.
a - Tell my wife I love her.

You can use tld -r ID to "remove" an item (which won't mark it as "finished". Items marked "finished" can be listed. Items that are "removed" are just gone).

Edit an Item

Sometimes you might want to change the wording of an item. You can use tld -e ID [new description] to do that:

$ tld -e 1 Clean my .vimrc.
$ tld
5 - Update my .vimrc.
a - Tell my wife I love her.

Yes, you can use sed-style substitution strings s/old/repl.

$ tld -e 5 s/Update/Clean/
$ tld
a - Tell my wife I love her.
e - Clean my .vimrc.

List "Finished" Items

Have you marked lots of items as "finished" and you want to review them? You can view these items with tld --done.

$ tld --done
b - Prove the Riemann Hypothesis.

Annotate Items with Dates

Do you want to be able to remember when you added an item to the list? Use tld --date [description] when you add the item to the list.

$ tld --date Write README.
$ tld
1 - Write Readme.
5 - Update my .vimrc.
a - Tell my wife I love her.

tld doesn't show these dates by default --- too much clutter. To see dates, use tld --showdates.

$ tld --showdates
2018-06-01 | 1 - Write README.
           | 5 - Update my .vimrc
           | a - Tell my wife I love her.

You can use --date in your tld alias, and this information will only affect the output when used with --showdates.

Annotate Items with Tags

Use tld --tag [TAG] [description] when you add an item to the list to add a tag.

$ tld --tag shopping Buy milk.
$ tld
1 - Write README.
5 - Update my .vimrc
9 - Buy milk.
a - Tell my wife I love her.

To see the tags, use --showtags.

$ tld --showtags
1 - Write README.
5 - Update my .vimrc
9 - Buy milk. | tags: shopping
a - Tell my wife I love her.

Delete the List if it's Empty

Why keep an empty list around? You can have the list delete itself automatically if empty. You can use the --delete-if-empty option in your alias:

alias tld='python3 ~/path/to/tld.py --task-dir ~/notes/tasks --list tasks --delete_if-empty'

Tips and Tricks

tld might be simple, but it can do a lot of interesting things.

Count Your Items

Counting your item is simple using the wc program:

$ tld | wc -l
4

Tags, Grep, Awk, and Sed

If I have too many aliases, I forget them. I use tags and grep as a primary level of organization. To remember what tags exist, just print them with tld --showtags or tld --showtags | grep tags. Then print out the relevant items through grep with tld --showtags | grep shopping.

$ tld --showtags | grep shopping
9 - Buy milk. | tags: shopping

To make it look pretty, you can cut out the tag by showing evertying before '|' with something like awk.

$ tld --showtags | grep shopping | awk -F'|' '{print $1}'
9 - Buy milk. 

If you have too many tags and too many items, then perhaps having multiple lists is a good idea for you. But you can list all the unique collections of tags relatively easily with classic tools and sed.

$ tld --tag shopping Buy chocolate syrup.
$ tld --tag music Buy Phoenix album.
$ tld --showtags | grep tags | sed -e's/.*tags: //' | sort | uniq
music
shopping

Multiple Lists

You can follow the t.py philosophy of organizing tasks into different lists by adding additional aliases. For example

alias g='python ~/path/to/tld.py --task-dir ~/notes/tasks --list groceries'
alias m='python ~/path/to/tld.py --task-dir ~/notes/tasks --list music-to-buy'
alias w='python ~/path/to/tld.py --task-dir ~/notes/tasks --list wines-to-try'

Distributed Bugtracking

Like the idea of distributed bug trackers like [BugsEverywhere][], but don't want to use such a heavyweight system? You can use tld instead.

Add another alias to your ~/.bashrc file:

alias b='python ~/path/to/tld.py --task-dir . --list bugs'

Now when you're in your project directory you can use b to manage the list of bugs/tasks for that project. Add the bugs file to version control and you're all set.

Even people without tld installed can view the bug list, because it's plain text.

On Compatability with t.py

tld can read and operate on lists made with t.py, but t.py does not handle the date and tag annotations from tld. If you never use those, then they're interoperable (and you're essentially using t.py anyway).

In the future, additional metadata may be implemented in tld, which may further widen this gap.

Why Make tld?

I used Steve Losh's t.py for a long time before deciding to make a few changes. When I read through his code, I thought it was pretty elegant. So I thought it would be a good learning experience to rebuild it in roughly the same order, but with a few changes in mind.

So really, this project is an exercise in programming that I did over about a week to fit my whims and desires.

Those who find themselves here should really check out t.py. By adding new features, I satisfy my whims --- but more features ruin the simple purity of the original t.py.

Bugs and Contributions

If you happen to use it and find a bug, let me know.

For more featureful list managers, you might checko out todo.txt and TaskWarrior. They have lots of features and lots of knobs that one can tweak and prettify.

If you want to contribute code to tld, that's great! Fork the repo and send me a pull request. But I've been doing this as a learning experience, and know that I might experiment with contributed code too.
