=head1 NAME

cryp-exchange - Interact with cryptoexchanges

=head1 VERSION

This document describes version 0.005 of cryp-exchange (from Perl distribution App-cryp-exchange), released on 2018-06-08.

=head1 SYNOPSIS

Create configuration in F<~/.config/cryp-exchange.conf> (or
F<~/.config/cryp.conf> so configuration can be shared with the other C<cryp-*>
family of scripts):

 [exchange/bitcoin-indonesia]
 api_key    = S6WBYR6Q-TVMTSFOA-YWK6GSNT-H0JMEK6Z-YDF5ML9Y
 api_secret = e16064aa7fb477b267fe774df62194f33583c7f46a09ad931ca2e097aeaa9c9296e1c3b2734bab71

 ; if you have another account on the same exchange
 [exchange/bitcoin-indonesia/wifey]
 api_key    = EKSGJUOR-ROR9K24P-Q45UBWVG-GZHANPQV-UY4Z1WBM
 api_secret = 71100dc13ffe4d082239c06b5c36fd8f0548cd97056ffa2ee491ae4dfd4f996fb468ef3c70b12073

 [exchange/gdax]
 api_key        = 2171d01f1de2518c94a11870a6df22d0
 api_secret     = 9B8T2nPFMRUiUIKA82txjaO09iNnJXBMVMdkDgJ0i2YambYKQY8DZAS54ERZE0sE2lzYrpTWfpU7/110xfesZluY
 api_passphrase = gdllszgwO774NN

To list supported exchanges:

 % cryp-exchange ls-exchanges
 % cryp-exchange ls-exchanges -l

To list pairs offered in an exchange:

 % cryp-exchange ls-pairs bitcoin-indonesia
 % cryp-exchange ls-pairs gdax -l

To list accounts:

 % cryp-exchange ls-accounts
 % cryp-exchange ls-accounts -l
 % cryp-exchange ls-accounts -I gdax -l ;# only accounts on gdax
 % cryp-exchange ls-accounts -X gdax -l ;# all accounts except those on gdax

To get order book:

 % cryp-exchange get-order-book gdax

=head1 DESCRIPTION

B<Early release. More functionality will be added in the future.>

This utility (and the corresponding backend modules) provide a common interface
to interact with various cryptocurrency exchanges: common set of subcommands
(methods) with common arguments and result format, standardized currency codes
(following L<CryptoCurrency::Catalog>) and pair formats (e.g. C<BTC/USD>).

=head1 SUBCOMMANDS

=head2 B<get-order-book>

Get order book on an exchange.

=head2 B<ls-accounts>

List exchange accounts.

=head2 B<ls-balances>

List account balances.

=head2 B<ls-exchanges>

List supported exchanges.

=head2 B<ls-pairs>

List pairs supported by exchange.

=head1 OPTIONS

C<*> marks required options.

=head2 Common options

=over

=item B<--config-path>=I<filename>

Set path to configuration file.

Can be specified multiple times.

=item B<--config-profile>=I<s>

Set configuration profile to use.

=item B<--debug>

Shortcut for --log-level=debug.

=item B<--format>=I<s>

Choose output format, e.g. json, text.

Default value:

 undef

=item B<--help>, B<-h>, B<-?>

Display help message and exit.

=item B<--json>

Set output format to json.

=item B<--log-level>=I<s>

Set log level.

=item B<--naked-res>

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

    [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd
element) as well as result metadata/extra result (4th element) instead of just
the result (3rd element). However, sometimes you want just the result, e.g. when
you want to pipe the result for more post-processing. In this case you can use
`--naked-res` so you just get:

    [1,2,3]


=item B<--no-config>

Do not use any configuration file.

=item B<--no-env>

Do not read environment for default options.

=item B<--quiet>

Shortcut for --log-level=error.

=item B<--subcommands>

List available subcommands.

=item B<--trace>

Shortcut for --log-level=trace.

=item B<--verbose>

Shortcut for --log-level=info.

=item B<--version>, B<-v>

Display program's version and exit.

=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C cryp-exchange cryp-exchange

in your bash startup (e.g. F<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install modules using L<cpanm-shcompgen>
which can activate shell completion for scripts immediately.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete cryp-exchange 'p/*/`cryp-exchange`/'

in your tcsh startup (e.g. F<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install L<shcompgen> (see above).

=head2 other shells

For fish and zsh, install L<shcompgen> as described above.

=head1 CONFIGURATION FILE

This script can read configuration files. Configuration files are in the format of L<IOD>, which is basically INI with some extra features.

By default, these names are searched for configuration filenames (can be changed using C<--config-path>): F<~/.config/cryp.conf>, F<~/.config/cryp-exchange.conf>, F<~/cryp.conf>, F<~/cryp-exchange.conf>, F</etc/cryp.conf>, or F</etc/cryp-exchange.conf>.

All found files will be read and merged.

To disable searching for configuration files, pass C<--no-config>.

To put configuration for a certain subcommand only, use a section name like C<[subcommand=NAME]> or C<[SOMESECTION subcommand=NAME]>.

You can put multiple profiles in a single file by using section names like C<[profile=SOMENAME]> or C<[SOMESECTION profile=SOMENAME]> or C<[subcommand=SUBCOMMAND_NAME profile=SOMENAME]> or C<[SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]>. Those sections will only be read if you specify the matching C<--config-profile SOMENAME>.

You can also put configuration for multiple programs inside a single file, and use filter C<program=NAME> in section names, e.g. C<[program=NAME ...]> or C<[SOMESECTION program=NAME]>. The section will then only be used when the reading program matches.

Finally, you can filter a section by environment variable using the filter C<env=CONDITION> in section names. For example if you only want a section to be read if a certain environment variable is true: C<[env=SOMEVAR ...]> or C<[SOMESECTION env=SOMEVAR ...]>. If you only want a section to be read when the value of an environment variable has value equals something: C<[env=HOSTNAME=blink ...]> or C<[SOMESECTION env=HOSTNAME=blink ...]>. If you only want a section to be read when the value of an environment variable does not equal something: C<[env=HOSTNAME!=blink ...]> or C<[SOMESECTION env=HOSTNAME!=blink ...]>. If you only want a section to be read when an environment variable contains something: C<[env=HOSTNAME*=server ...]> or C<[SOMESECTION env=HOSTNAME*=server ...]>. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.
