This commit adds the --socket option to use hledger-web over an AF_UNIX socket
file.
It allows running multiple instances of hledger-web on the same system without
having to manually choose a port for each instance, which is helpful for running
individual instances for multiple users. In this scenario, the socket path is
predictable, as it can be derived from the username.
It also introduces the following dependencies:
- network
- Used to create the unix domain socket
- unix-compat
- Used to identify if the socket file is still a socket, to reduce the risk
of deleting a file when cleaning up the socket
It seems like show (toJSON "a") used to give "\"a\"" instead of
"String \"a\"". I haven't found the root cause, it's possible
that this fix won't work if built with older libs.
- Modified the cors option to require a String
- Moved the logic to build the cors policy to WebOptions.hs
- Specify the --cors "*" example in the cors option help
- Added utf8-string dependency to convert a String into a ByteString
dropped journalPrices
renamed Price to AmountPrice, AKA "transaction price"
renamed MarketPrice to PriceDirective.
added new MarketPrice (more pure form of PriceDirective without the amount style information)
Prices is now a more efficient data structure, but not used yet.
These Ledger-ish spellings were dropped over the years, to improve
--help's layout. Now they work again, but are considered hidden flags
so --help doesn't show them automatically (but I decided to mention
them manually in --date2's description).
A single transaction can be added by PUT to /add.
(I read that PUT, not POST, should be used to create;
perhaps the web add form should also use PUT ?)
As with the web form, the `add` capability is required (and enabled by
default).
Here's how to test with curl:
$ curl -s http://127.0.0.1:5000/add -X PUT -H 'Content-Type: application/json' --data-binary @in.json; echo
New readJsonFile/writeJsonFile helpers in Hledger.Web.Json
are handy for generating test data. Eg:
>>> writeJsonFile "in.json" (head $ jtxns samplejournal)
