It's not necessary to install TreeDraw locally. You can use it over the internet (courtesy of Osaka Kyoiku University): just go here.
But if you prefer running it locally on your Windows 10 machine, follow these instructions.
Download TreeDraw.zip here (7.3MB). No installer package is currently provided. (Someday there'll be a nice installer.)
However, installation only takes a few simple steps:
Next, locate the file index.html, also in
C:/Program Files/TreeDraw.
Double click on it. It should automatically load into a browser.
(Your interaction with TreeDraw will be via this browser page, C:\Program Files\TreeDraw\index.html.)
Bookmark this page for easy access. (Or create a Desktop shortcut by right clicking on the file.)
Installation is now complete.
To start TreeDraw double click on the Desktop shortcut. Click OK to allow it to open a console. (Someday, we won't need this step.)
(To quit TreeDraw, simply close the open console. You can safely minimize (_) the console window without quitting TreeDraw.)
Windows Defender is sometimes overaggressive on port security and may pop up a message like this:
You should permit TreeDraw.exe to communicate over private and public networks (even though it doesn't).
Load file C:\Program Files\TreeDraw\index.html into your browser. Type your bracketed expressions into the Input box. There are four formats currently documented: hit expand under Help to see examples.
(Note: closing the browser page does not quit TreeDraw. You may open
multiple browser pages to TreeDraw. You can reload the page safely.
To quit TreeDraw altogether, close the console window. You can run
multiple copies of TreeDraw, but only the first one works.)
(You can also type pid followed by return (or ⇇Send) to see the process id of the connected TreeDraw app.)
