The hledger-web tests have been cleaned up and now allow more testing
of command line options like (though still not everything).
Note tests now run the app listening on its default host and port,
127.0.0.1 and 5000, instead of "any IPv4 or IPv6 hostname" and 3000.
This would seem to mean hledger-web tests can conflict more with
things running on port 5000, eg a normal hledger-web instance, but I
haven't been able to reproduce it.
Now not broken, https rather than http, and pointing to the "Data
formats" section, which has links to each of the file formats
(in case editing a non-journal file).
This commit introduces IPv6 support (and thus closes#1145).
It also allows using local hostnames as a parameter for --host.
For this, multiple things needed to be changed:
- checkWebOpts is dropped, as the supplied parameter is checked later
by Network.Socket.getAddrInfo
- defbaseurl needs to check if : is used in the host, as this indicates
the usage of an IPv6 address. In this case, the host needs to be
wrapped in [] for the base URL
- To allow opening such a modified base URL, runHostPortFullUrl is used
instead of runhostPortUrl, as it allows opening arbitrary URLs instead
of a path prefixed with http://127.0.0.1
As checking the host for validity is postponed until the webserver tries
to start, an invalid hostname leads to an exception caused by
Network.Socket.getAddrInfo.
This is still fine, as hledger-web won't start in an undefined state, but
will terminate with a nonzero exit code.
This is a compromise to ease deployment and satisfy hamlet's requirements.
See the Hledger.Web.Files module for more info. Currently we exit after
creating the missing files since they are not created early enough for
hamlet.
