Subject: [bug#30657] [PATCH 4/4] services: messaging: Prosody config supports file-like objects.
Date: Wed, 28 Feb 2018 23:28:21 +0100 [thread overview]
Message-ID: <20180228222821.6195-4-clement@lassieur.org> (raw)
In-Reply-To: <20180228222821.6195-1-clement@lassieur.org>
* doc/guix.texi (Messaging Services): Update accordingly.
* gnu/services/messaging.scm (serialize-field, enclose-quotes,
serialize-raw-content, serialize-ssl-configuration,
serialize-virtualhost-configuration, serialize-int-component-configuration,
serialize-ext-component-configuration, prosody-activation): Replace 'format'
with 'push-token' and 'with-output-to-string' with 'with-tokens-to-list'.
(prosody-activation): Replace 'plain-file' with 'mixed-text-file' and flatten
the tokens.
(serialize-non-negative-integer, serialize-non-negative-integer-list): Convert
numbers to strings.
(file-object?, serialize-file-object, file-object-list?,
serialize-file-object-list): New procedures.
(ssl-configuration)[capath, cafile], (prosody-configuration)[plugin-paths,
groups-file]: Replace 'file-name' with 'file-object'.
