hledgerdescription
web({{
}})
hledger-web is hledger’s web interface. It starts a simple web application for browsing and adding transactions, and optionally opens it in a web browser window if possible. It provides a more user-friendly UI than the hledger CLI or hledger-ui interface, showing more at once (accounts, the current account register, balance charts) and allowing history-aware data entry, interactive searching, and bookmarking.
hledger-web also lets you share a ledger with multiple users, or even the public web. There is no access control, so if you need that you should put it behind a suitable web proxy. As a small protection against data loss when running an unprotected instance, it writes a numbered backup of the main journal file (only ?) on every edit.
Like hledger, it reads files For more about this see hledger(1), hledger_journal(5) etc.
OPTIONS
Command-line options and arguments may be used to set an initial filter on the data. These filter options are not shown in the web UI, but it will be applied in addition to any search query entered there.
Note: if invoking hledger-web as a hledger subcommand, write
-- before options, as shown in the synopsis above.
--serve- serve and log requests, don’t browse or auto-exit
--serve-api- like –serve, but serve only the JSON web API, without the server-side web UI
--host=IPADDR- listen on this IP address (default: 127.0.0.1)
--port=PORT- listen on this TCP port (default: 5000)
--socket=SOCKETFILE-
use a unix domain socket file to listen for requests instead of a TCP
socket. Implies
--serve. It can only be used if the operating system can provide this type of socket. --base-url=URL- set the base url (default: http://IPADDR:PORT). You would change this when sharing over the network, or integrating within a larger website.
--file-url=URL- set the static files url (default: BASEURL/static). hledger-web normally serves static files itself, but if you wanted to serve them from another server for efficiency, you would set the url with this.
--capabilities=CAP[,CAP..]- enable the view, add, and/or manage capabilities (default: view,add)
--capabilities-header=HTTPHEADER- read capabilities to enable from a HTTP header, like X-Sandstorm-Permissions (default: disabled)
hledger input options:
inputoptions
hledger reporting options:
reportingoptions
hledger help options:
helpoptions
A @FILE argument will
be expanded to the contents of FILE, which should contain one command
line option/argument per line. (To prevent this, insert a
-- argument before.)
By default, hledger-web starts the web app in “transient mode” and
also opens it in your default web browser if possible. In this mode the
web app will keep running for as long as you have it open in a browser
window, and will exit after two minutes of inactivity (no requests and
no browser windows viewing it). With --serve, it just runs
the web app without exiting, and logs requests to the console. With
--serve-api, only the JSON web api (see below) is served,
with the usual HTML server-side web UI disabled.
By default the server listens on IP address 127.0.0.1, accessible
only to local requests. You can use --host to change this,
eg --host 0.0.0.0 to listen on all configured
addresses.
Similarly, use --port to set a TCP port other than 5000,
eg if you are running multiple hledger-web instances.
Both of these options are ignored when --socket is used.
In this case, it creates an AF_UNIX socket file at the
supplied path and uses that for communication. This is an alternative
way of running multiple hledger-web instances behind a reverse proxy
that handles authentication for different users. The path can be derived
in a predictable way, eg by using the username within the path. As an
example, nginx as reverse proxy can use the variabel
$remote_user to derive a path from the username used in a
HTTP
basic authentication. The following proxy_pass
directive allows access to all hledger-web instances that
created a socket in /tmp/hledger/:
proxy_pass http://unix:/tmp/hledger/${remote_user}.socket;
You can use --base-url to change the protocol, hostname,
port and path that appear in hyperlinks, useful eg for integrating
hledger-web within a larger website. The default is
http://HOST:PORT/ using the server’s configured host
address and TCP port (or http://HOST if PORT is 80).
With --file-url you can set a different base url for
static files, eg for better caching or cookie-less serving on high
performance websites.
PERMISSIONS
By default, hledger-web allows anyone who can reach it to view the journal and to add new transactions, but not to change existing data.
You can restrict who can reach it by
- setting the IP address it listens on (see
--hostabove). By default it listens on 127.0.0.1, accessible to all users on the local machine. - putting it behind an authenticating proxy, using eg apache or nginx
- custom firewall rules
You can restrict what the users who reach it can do, by
- using the
--capabilities=CAP[,CAP..]flag when you start it, enabling one or more of the following capabilities. The default value isview,add:view- allows viewing the journal file and all included filesadd- allows adding new transactions to the main journal filemanage- allows editing, uploading or downloading the main or included files
- using the
--capabilities-header=HTTPHEADERflag to specify a HTTP header from which it will read capabilities to enable. hledger-web on Sandstorm uses the X-Sandstorm-Permissions header to integrate with Sandstorm’s permissions. This is disabled by default.
EDITING, UPLOADING, DOWNLOADING
If you enable the manage capability mentioned above,
you’ll see a new “spanner” button to the right of the search form.
Clicking this will let you edit, upload, or download the journal file or
any files it includes.
Note, unlike any other hledger command, in this mode you (or any visitor) can alter or wipe the data files.
Normally whenever a file is changed in this way, hledger-web saves a numbered backup (assuming file permissions allow it, the disk is not full, etc.) hledger-web is not aware of version control systems, currently; if you use one, you’ll have to arrange to commit the changes yourself (eg with a cron job or a file watcher like entr).
Changes which would leave the journal file(s) unparseable or non-valid (eg with failing balance assertions) are prevented. (Probably. This needs re-testing.)
RELOADING
hledger-web detects changes made to the files by other means (eg if you edit it directly, outside of hledger-web), and it will show the new data when you reload the page or navigate to a new page. If a change makes a file unparseable, hledger-web will display an error message until the file has been fixed.
(Note: if you are viewing files mounted from another machine, make sure that both machine clocks are roughly in step.)
JSON API
In addition to the web UI, hledger-web also serves a JSON API that
can be used to get data or add new transactions. If you want the JSON
API only, you can use the --serve-api flag. Eg:
$ hledger-web -f examples/sample.journal --serve-api
...
You can get JSON data from these routes:
/accountnames
/transactions
/prices
/commodities
/accounts
/accounttransactions/ACCOUNTNAME
Eg, all account names in the journal (similar to the accounts command). (hledger-web’s JSON does not include newlines, here we use python to prettify it):
$ curl -s http://127.0.0.1:5000/accountnames | python -m json.tool
[
"assets",
"assets:bank",
"assets:bank:checking",
"assets:bank:saving",
"assets:cash",
"expenses",
"expenses:food",
"expenses:supplies",
"income",
"income:gifts",
"income:salary",
"liabilities",
"liabilities:debts"
]
Or all transactions:
$ curl -s http://127.0.0.1:5000/transactions | python -m json.tool
[
{
"tcode": "",
"tcomment": "",
"tdate": "2008-01-01",
"tdate2": null,
"tdescription": "income",
"tindex": 1,
"tpostings": [
{
"paccount": "assets:bank:checking",
"pamount": [
{
"acommodity": "$",
"aismultiplier": false,
"aprice": null,
...
Most of the JSON corresponds to hledger’s data types; for details of what the fields mean, see the Hledger.Data.Json haddock docs and click on the various data types, eg Transaction. And for a higher level understanding, see the journal manual.
In some cases there is outer JSON corresponding to a “Report” type.
To understand that, go to the Hledger.Web.Handler.MiscR
haddock and look at the source for the appropriate handler to see
what it returns. Eg for /accounttransactions it’s getAccounttransactionsR,
returning a “accountTransactionsReport ...”. Looking
up the haddock for that we can see that /accounttransactions returns
an AccountTransactionsReport,
which consists of a report title and a list of
AccountTransactionsReportItem (etc).
You can add a new transaction to the journal with a PUT request to
/add, if hledger-web was started with the add
capability (enabled by default). The payload must be the full, exact
JSON representation of a hledger transaction (partial data won’t do).
You can get sample JSON from hledger-web’s /transactions or
/accounttransactions, or you can export it with
hledger-lib, eg like so:
.../hledger$ stack ghci hledger-lib
>>> writeJsonFile "txn.json" (head $ jtxns samplejournal)
>>> :q
Here’s how it looks as of hledger-1.17 (remember, this JSON corresponds to hledger’s Transaction and related data types):
{
"tcomment": "",
"tpostings": [
{
"pbalanceassertion": null,
"pstatus": "Unmarked",
"pamount": [
{
"aprice": null,
"acommodity": "$",
"aquantity": {
"floatingPoint": 1,
"decimalPlaces": 10,
"decimalMantissa": 10000000000
},
"aismultiplier": false,
"astyle": {
"ascommodityside": "L",
"asdigitgroups": null,
"ascommodityspaced": false,
"asprecision": 2,
"asdecimalpoint": "."
}
}
],
"ptransaction_": "1",
"paccount": "assets:bank:checking",
"pdate": null,
"ptype": "RegularPosting",
"pcomment": "",
"pdate2": null,
"ptags": [],
"poriginal": null
},
{
"pbalanceassertion": null,
"pstatus": "Unmarked",
"pamount": [
{
"aprice": null,
"acommodity": "$",
"aquantity": {
"floatingPoint": -1,
"decimalPlaces": 10,
"decimalMantissa": -10000000000
},
"aismultiplier": false,
"astyle": {
"ascommodityside": "L",
"asdigitgroups": null,
"ascommodityspaced": false,
"asprecision": 2,
"asdecimalpoint": "."
}
}
],
"ptransaction_": "1",
"paccount": "income:salary",
"pdate": null,
"ptype": "RegularPosting",
"pcomment": "",
"pdate2": null,
"ptags": [],
"poriginal": null
}
],
"ttags": [],
"tsourcepos": {
"tag": "JournalSourcePos",
"contents": [
"",
[
1,
1
]
]
},
"tdate": "2008-01-01",
"tcode": "",
"tindex": 1,
"tprecedingcomment": "",
"tdate2": null,
"tdescription": "income",
"tstatus": "Unmarked"
}
And here’s how to test adding it with curl. This should add a new entry to your journal:
$ curl http://127.0.0.1:5000/add -X PUT -H 'Content-Type: application/json' --data-binary @txn.json

BUGS
The need to precede options with -- when invoked from
hledger is awkward.
-f- doesn’t work (hledger-web can’t read from
stdin).
Query arguments and some hledger options are ignored.
Does not work in text-mode browsers.
Does not work well on small screens.
