HLEDGER-WEB(1) hledger User Manuals HLEDGER-WEB(1)
NAME
hledger-web - web interface and API for hledger, a robust, friendly
plain text accounting app.
SYNOPSIS
hledger-web [OPTS] [QUERY]
or
hledger web -- [OPTS] [QUERY]
DESCRIPTION
This manual is for hledger's web interface, version 1.34.99. See also
the hledger manual for common concepts and file formats.
hledger is a robust, user-friendly, cross-platform set of programs for
tracking money, time, or any other commodity, using double-entry ac-
counting and a simple, editable file format. hledger is inspired by
and largely compatible with ledger(1), and largely interconvertible
with beancount(1).
hledger-web is a simple web application for browsing and adding trans-
actions. It provides a more user-friendly UI than the hledger CLI or
hledger-ui TUI, showing more at once (accounts, the current account
register, balance charts) and allowing history-aware data entry, inter-
active searching, and bookmarking.
hledger-web also lets you share a journal 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 from (and appends to) a journal file specified
by the LEDGER_FILE environment variable (defaulting to
$HOME/.hledger.journal); or you can specify files with -f options. It
can also read timeclock files, timedot files, or any CSV/SSV/TSV file
with a date field. (See hledger(1) -> Input for details.)
hledger-web can be run in three modes:
o Transient mode (the default): your default web browser will be opened
to show the app if possible, and the app exits automatically after
two minutes of inactivity (no requests received and no open browser
windows viewing it).
o With --serve: the app runs without stopping, and without opening a
browser.
o With --serve-api: only the JSON API is served.
In all cases hledger-web runs as a foreground process, logging requests
to stdout.
OPTIONS
hledger-web provides the following options:
Flags:
--serve --server serve and log requests, don't browse or auto-exit
--serve-api like --serve, but serve only the JSON web API,
not the web UI
--allow=view|add|edit set the user's access level for changing data
(default: `add`). It also accepts `sandstorm` for
use on that platform (reads permissions from the
`X-Sandstorm-Permissions` request header).
--cors=ORIGIN allow cross-origin requests from the specified
origin; setting ORIGIN to "*" allows requests from
any origin
--host=IPADDR listen on this IP address (default: 127.0.0.1)
--port=PORT listen on this TCP port (default: 5000)
--socket=SOCKET listen on the given unix socket instead of an IP
address and port (unix only; implies --serve)
--base-url=BASEURL set the base url (default: http://IPADDR:PORT)
--test run hledger-web's tests and exit. hspec test
runner args may follow a --, eg: hledger-web --test
-- --help
By default hledger-web listens only on IP address 127.0.0.1, which be
accessed only from the local machine.
To allow access from elsewhere, use --host to specify an externally ac-
cessible address configured on this machine, The special address
0.0.0.0 causes it to listen on all of this machine's addresses.
Similarly, you can use --port to listen on a TCP port other than 5000.
This is useful if you want to run multiple hledger-web instances on a
machine.
When --socket is used, hledger-web creates and communicates via a
socket file instead of a TCP port. This can be more secure, respects
unix file permissions, and makes certain use cases easier, such as run-
ning per-user instances behind an nginx reverse proxy. (Eg: 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 hledger-web's hyperlinks. This is useful eg when inte-
grating 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). Note this affects url generation
but not route parsing.
hledger-web also supports many of hledger's general options:
General input/data transformation flags:
-f --file=[FMT:]FILE Read data from FILE, or from stdin if FILE is -,
inferring format from extension or a FMT: prefix.
Can be specified more than once. If not specified,
reads from $LEDGER_FILE or $HOME/.hledger.journal.
--rules=RULESFILE Use rules defined in this rules file for
converting subsequent CSV/SSV/TSV files. If not
specified, uses FILE.csv.rules for each FILE.csv.
--alias=A=B|/RGX/=RPL transform account names from A to B, or by
replacing regular expression matches
--auto generate extra postings by applying auto posting
rules ("=") to all transactions
--forecast[=PERIOD] Generate extra transactions from periodic rules
("~"), from after the latest ordinary transaction
until 6 months from now. Or, during the specified
PERIOD (the equals is required). Auto posting rules
will also be applied to these transactions. In
hledger-ui, also make future-dated transactions
visible at startup.
-I --ignore-assertions don't check balance assertions by default
--infer-costs infer conversion equity postings from costs
--infer-equity infer costs from conversion equity postings
--infer-market-prices infer market prices from costs
--pivot=TAGNAME use a different field or tag as account names
-s --strict do extra error checks (and override -I)
--verbose-tags add tags indicating generated/modified data
General output/reporting flags (supported by some commands):
-b --begin=DATE include postings/transactions on/after this date
-e --end=DATE include postings/transactions before this date
(with a report interval, will be adjusted to
following subperiod end)
-D --daily multiperiod report with 1 day interval
-W --weekly multiperiod report with 1 week interval
-M --monthly multiperiod report with 1 month interval
-Q --quarterly multiperiod report with 1 quarter interval
-Y --yearly multiperiod report with 1 year interval
-p --period=PERIODEXP set begin date, end date, and/or report interval,
with more flexibility
--today=DATE override today's date (affects relative dates)
--date2 match/use secondary dates instead (deprecated)
-U --unmarked include only unmarked postings/transactions
-P --pending include only pending postings/transactions
-C --cleared include only cleared postings/transactions
(-U/-P/-C can be combined)
-R --real include only non-virtual postings
--depth=NUM or -NUM: show only top NUM levels of accounts
-E --empty Show zero items, which are normally hidden.
In hledger-ui & hledger-web, do the opposite.
-B --cost show amounts converted to their cost/sale amount
-V --market Show amounts converted to their value at period
end(s) in their default valuation commodity.
Equivalent to --value=end.
-X --exchange=COMM Show amounts converted to their value at period
end(s) in the specified commodity.
Equivalent to --value=end,COMM.
--value=WHEN[,COMM] show amounts converted to their value on the
specified date(s) in their default valuation
commodity or a specified commodity. WHEN can be:
'then': value on transaction dates
'end': value at period end(s)
'now': value today
YYYY-MM-DD: value on given date
-c --commodity-style=S Override a commodity's display style.
Eg: -c '.' or -c '1.000,00 EUR'
--color=YN --colour Use ANSI color codes in text output? Can be
'y'/'yes'/'always', 'n'/'no'/'never' or 'auto'.
--pretty[=YN] Use box-drawing characters in text output? Can be
'y'/'yes' or 'n'/'no'.
If YN is specified, the equals is required.
General help flags:
-h --help show command line help
--tldr show command examples with tldr
--info show the manual with info
--man show the manual with man
--version show version information
--debug=[1-9] show this level of debug output (default: 1)
hledger-web shows accounts with zero balances by default (like
hledger-ui, and unlike hledger). Using the -E/--empty flag will re-
verse this behaviour. If you see accounts which appear to have a zero
balance, but cannot be hidden with -E, it's because they have a
mixed-cost balance, which looks like zero when costs are hidden.
(hledger-web does not show costs.)
Reporting options and/or query arguments can be used to set an initial
query, which although not shown in the UI, will restrict the data shown
(in addition to any search query entered in the UI).
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
o setting the IP address it listens on (see --host above). By default
it listens on 127.0.0.1, accessible to all users on the local ma-
chine.
o putting it behind an authenticating proxy, using eg apache or nginx
o custom firewall rules
You can restrict what the users who reach it can do, by
o using the --capabilities=CAP[,CAP..] flag when you start it, enabling
one or more of the following capabilities. The default value is
view,add:
o view - allows viewing the journal file and all included files
o add - allows adding new transactions to the main journal file
o manage - allows editing, uploading or downloading the main or in-
cluded files
o using the --capabilities-header=HTTPHEADER flag 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 in-
cludes.
Note, unlike any other hledger command, in this mode you (or any visi-
tor) 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, cur-
rently; 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 un-
til 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:
/version
/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": "$",
"aismultiplier": false,
"aprice": null,
...
Most of the JSON corresponds to hledger's data types; for details of
what the fields mean, see the Hledger.Data.Json haddock docs and click
on the various data types, eg Transaction. And for a higher level un-
derstanding, see the journal docs. There is also a basic OpenAPI spec-
ification.
In some cases there is outer JSON corresponding to a "Report" type. To
understand that, go to the Hledger.Web.Handler.MiscR haddock and look
at the source for the appropriate handler to see what it returns. Eg
for /accounttransactions it's getAccounttransactionsR, returning a "ac-
countTransactionsReport ...". Looking up the haddock for that we can
see that /accounttransactions returns an AccountTransactionsReport,
which consists of a report title and a list of AccountTransactionsRe-
portItem (etc).
You can add a new transaction to the journal with a PUT request to
/add, if hledger-web was started with the add capability (enabled by
default). The payload must be the full, exact JSON representation of a
hledger transaction (partial data won't do). You can get sample JSON
from hledger-web's /transactions or /accounttransactions, or you can
export it with hledger-lib, eg like so:
.../hledger$ 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 en-
try to your journal:
$ curl http://127.0.0.1:5000/add -X PUT -H 'Content-Type: application/json' --data-binary @txn.json
DEBUG OUTPUT
Debug output
You can add --debug[=N] to the command line to log debug output. N
ranges from 1 (least output, the default) to 9 (maximum output). Typi-
cally you would start with 1 and increase until you are seeing enough.
Debug output goes to stderr, interleaved with the requests logged on
stdout. To capture debug output in a log file instead, you can usually
redirect stderr, eg:
hledger-web --debug=3 2>hledger-web.log.
ENVIRONMENT
LEDGER_FILE The main journal file to use when not specified with
-f/--file. Default: $HOME/.hledger.journal.
