What is Hedgedoc?
Hedgedoc is a collaboration tool that let's multiple people work on the same document across the internet. It offers the ability to format text via markdown or via the formatting menu.
For the purposes of my testing and demo, I went the route of docker. The Hedgedoc documentation includes a sample
docker-compose.yml file. Below is the version I used with very minor tweaks for that.
I put the docker-compose.yml file in
~/yt_apps/hedgedoc then ran the following commands:
After the app fully started up, on the host machine I could navigate to
127.0.0.1:3000 to access Hedgedoc. To access it from another PC, I needed to navigate to the private IP address of that pc, Ex.
192.168.x.x:3000. Once there, I was greeted with the Hedgedoc homepage:
There are many authentication options including Twitter, Email, and Github. Here's a full list from the documentation as of July 2022:
I only kept email for my example and was able to setup a local account. From there, I was able to start creating notes.
Clicking on any of the options below will take you to a special document that walks through all the features Hedgedoc has:
Once in a file, the menu below appears on the top left:
The moon will switch between light and dark mode. To the left, the eye, side by side icon, and pencil icon opens up view mode, side by side mode, and edit mode respectively. Side by side shows a preview of the page in one pane and allows edits to be done in the other.
A menu on the right, shows the following:
Which allows a new file to be created or a view only publish link to be created. The Menu option allows for the file to be downloaded, as well as a few import options, and revisions.
After clicking into edit mode, across the top of the editing window, various formatting options will appear. All of these options can be performed via the menu or by the standard markdown keys astericks for italics, etc.
This is where the features started to surprise me. Near the bottom tucked away, this menu appears:
Clicking "Spaces" will change it to "Tab Size." The Spaces option is best for code like Python where indentation really matters. The most surprising however, is if SUBLIME is clicked, two more options appear:
To me, it's pretty crazy Hedgedoc has both a Vim and Emacs mode, and the Vim mode works as you'd expect, you can enter and exit Insert Mode just like you would in normal Vim.
The actual document itself allows for pasting or uploading images, Youtube video embeds, and even creating UML Diagrams. Other features like yaml meta data, Latex and PDF embeds are also included.
The last feature I want to mention though, was a big surprise. Hedgedoc offers a Slides mode, meaning if you setup your document correctly, you can present it as a slide show. While the formatting is limited, Slides mode does have options like transisitions, colored backgrounds and even video backgrounds. Pressing the 'S' key brings up the speaker view, which gives the speaker a view where they can see the current slide, their notes, the next slide and the time plus a timer.
I am curious how much Slide mode is used, because it's very fully featured. A lot of hard work went into making this mode great.
Hedgedoc is an excellent collaboration tool. The sheer amount of flexibilty allowed in this app is amazing. This would be an excellent option for someone that want to collaborate with others but wants an open source option. It looks like a lot of thought has been put into this app to make sure that basically any form of notes that need to be shared among a group of people can be shared in Hedgedoc.
