challenger.conf - Challenger configuration file
The configuration file is line-oriented.
Blank lines and whitespace at the beginning and end of a line are ignored.
Comments start with #
or %
in the first column
(after any beginning-of-line whitespace) and go to the end of the line.
The file is split into sections.
Every section begins with “[SECTIONNAME]” and
contains a number of options of the form “OPTION=VALUE”.
There may be whitespace around the =
(equal sign).
Section names and options are case-insensitive.
The values, however, are case-sensitive.
In particular, boolean values are one of YES
or NO
.
Values can include whitespace by surrounding
the entire value with "
(double quote).
Note, however, that there are no escape characters in such strings;
all characters between the double quotes (including other double quotes)
are taken verbatim.
Values that represent filenames can begin with a /bin/sh
-like
variable reference.
This can be simple, such as $TMPDIR/foo
, or complex,
such as ${TMPDIR:-${TMP:-/tmp}}/foo
.
See [PATHS]
(below).
Values that represent a time duration are represented as a series
of one or more NUMBER UNIT
pairs, e.g. 60 s
, 4 weeks 1 day
,
5 years 2 minutes
.
Values that represent an amount are in the usual amount syntax:
CURRENCY:VALUE.FRACTION
, e.g. EUR:1.50
.
The FRACTION
portion may extend up to 8 places.
The “[PATHS]” section is special in that it contains paths that can be
referenced using “$” in other configuration values that specify
filenames. Note that configuration options that are not specifically
retrieved by the application as filenames will not see “$”-expressions
expanded. To expand “$”-expressions when using taler-config
, you must pass
the -f
command-line option.
The system automatically pre-populates the “[PATHS]” section with a few values
at run-time in addition to the values that are in the actual configuration
file. These automatically generated values refer to installation properties
from GNU autoconf. The
values are usually dependent on an INSTALL_PREFIX
which is determined by
the --prefix
option given to configure. The canonical values are:
- LIBEXECDIR = $INSTALL_PREFIX/taler/libexec/
- DOCDIR = $INSTALL_PREFIX/share/doc/taler/
- ICONDIR = $INSTALL_PREFIX/share/icons/
- LOCALEDIR = $INSTALL_PREFIX/share/locale/
- PREFIX = $INSTALL_PREFIX/
- BINDIR = $INSTALL_PREFIX/bin/
- LIBDIR = $INSTALL_PREFIX/lib/taler/
- DATADIR = $INSTALL_PREFIX/share/taler/
Note that on some platforms, the given paths may differ depending on how the system was compiled or installed, the above are just the canonical locations of the various resources.
Files containing default values for many of the options described below
are installed under $PREFIX/share/challenger/config.d/
.
The configuration file given with -c to Challenger binaries
overrides these defaults.
A configuration file may include another, by using the @INLINE@
directive,
for example, in main.conf
, you could write @INLINE@ sub.conf
to
include the entirety of sub.conf
at that point in main.conf
.
Be extra careful when using challenger-config -V VALUE
to change configuration
values: it will destroy all uses of @INLINE@
and furthermore remove all
comments from the configuration file!
The following options are from the “[challenger]” section. This is normally the only section in a challenger.conf file.
tcp
or unix
.SERVE
is tcp
.127.0.0.1
or ::1
for loopback. Can also be given as a hostname. We will bind to
the wildcard (dual-stack) if left empty.
Only used if SERVE
is tcp
.SERVE

.UNIXPATH

Only used if SERVE

./setup
to /token
). After this time, the garbage collection process can delete all associated data. (Note that tokens will always allow access to 1h after they have been issued, regardless of when the validation expires).address_type
in the /info
endpoint. Examples include email
or phone
.challenger-dbinit(1), challenger-httpd(1), challenger-config(1).
