The .hledger-web_client_session_key.aes file written at startup is
cluttersome and means hledger-web can only be started from a writable
directory. What do we lose if I disable it ?
https://hackage.haskell.org/package/yesod-core-1.4.33/docs/Yesod-Core.html#v:makeSessionBackend
says "Default: Uses clientsession with a 2 hour timeout."
http://hackage.haskell.org/package/clientsession-0.9.1.2 says
"Securely store session data in a client-side cookie."
I think: hledger-web saves (eg) the state of the sidebar as session
data, in a cookie, and my web browser saves that locally. And this
still seems to work, across server restarts. So what's the purpose of
saving this "client session" file on the server ? Let's disable it and
find out.
This also validates transaction date and description upon form submission. As noted in
the issue, this removes hledger-web's "smart date" functionality. This
functionality can be restored giving the demand but should be tracked in
another issue.
Previous iterations used input[type=date], but it isn't easily
crossbrowser and the polyfill I found had some quirks.
Now we have:
-- | Sorted unique account names posted to by this journal's transactions.
journalAccountNamesUsed :: Journal -> [AccountName]
-- | Sorted unique account names implied by this journal's transactions -
-- accounts posted to and all their implied parent accounts.
journalAccountNamesImplied :: Journal -> [AccountName]
-- | Sorted unique account names declared by account directives in this journal.
journalAccountNamesDeclared :: Journal -> [AccountName]
-- | Sorted unique account names declared by account directives or posted to
-- by transactions in this journal.
journalAccountNamesDeclaredOrUsed :: Journal -> [AccountName]
-- | Sorted unique account names declared by account directives, or posted to

journalAccountNamesDeclaredOrImplied :: Journal -> [AccountName]
-- | Convenience/compatibility alias for journalAccountNamesImpliedOrUsed.
