$ lein2 help webrepl | |
Start a web REPL session with the current project or standalone. | |
USAGE: lein2 webrepl [-n] [port] | [port] [-n] | |
This will launch an nREPL server behind the freshly started Jetty | |
instance and then open a fresh window of your default browser, connecting it | |
to the page featuring the nREPL front end. | |
The port value the Jetty is started on will be taken from command line, | |
if supplied. The LEIN_REPL_PORT environment variable is checked next, | |
then the value for the :repl-port key in project.clj, and finally it | |
will default to 8888. If port value is set to be zero, it is chosen randomly. | |
If option -n is supplied, no browser window will be opened. This is needed | |
when application is running on a remote host or when there is already | |
a browser window awaiting connection from the previous run. | |
For the time being (hopefully not for long) only one session | |
is supported per browser/per client computer, so if you have 2 or more windows | |
within the web browser connected to the same server, nREPL output will | |
be randomly sprinkled accros all of them. The workaround is to use | |
another browser type side by side (tested on Chrome, Firefox and Safari). | |
Note that REPL sessions are persistent - if you disconnect the browser for a | |
while and then load the REPL page again, all buffered session output | |
will be displayed in the output window. | |
If you run this command inside of a project, it will be run in | |
the context of that classpath and it will activate namespaces specified | |
by :main and :repl-init keys in project.clj when REPL session is established. | |
If the command is run outside of a project, it'll be standalone and the | |
classpath will be that of Leiningen. |
