Command line

abstract [dir]          open a workspace (default: the last one you opened,
                        else ~/Abstract/default)
abstract --port <n>     serve on a specific port
abstract --no-open      don't open the browser
abstract --version      print the version

Option	What it does
dir	The folder to open as a workspace. Without it, abstract reopens the last workspace you used, or ~/Abstract/default the first time. Your home folder (or the disk root) is never used as a workspace; asking for it opens ~/Abstract/default instead.
--port <n>, -p <n>	The port to use. The default is 4477 (change it permanently with port in config.json).
--no-open	Start without opening a browser tab.
--version, -v	Print the installed version, e.g. abstract 0.2.0.
--help, -h	Print the usage text.

What happens when it starts

  Abstract · workspace "my-review"
  http://localhost:4477

abstract serves the app on your own computer only (127.0.0.1) and opens your browser at that address. If the port is busy, it tries the next one (printing port 4477 is in use), up to 20 ports, and stops with no free port found if none is free.

Stop it with Ctrl+C. Work in progress is saved before it exits.

Examples

abstract                      # reopen the last workspace
abstract ~/thesis             # open a specific folder
abstract ~/thesis --port 5000 --no-open

You can run two workspaces at once in separate terminals; the second one takes the next free port.
