if_version tag?

ax · 2015-07-09 08:26:43

In view of anticipated changes in upcoming Textpattern versions, that could be non-compliant with existing applications, perhaps there is a need for a <txp:if_version> tag, that would allow more easily to up-/downgrade the whole system?

~~Isn’t that doable with reverse thinking and the <txp:if_plugin name="xyz_plugin" version="4"> tag?~~ Not really.

What version would it parse for those who use the svn or hacked installs?

gomedia · 2015-07-09 13:29:39

<txp:adi_globals name="version" />

<txp:if_variable name="version" value="4.5.7">
	Latest release!
</txp:if_variable>

At least if no further releases are planned. :) Such a tag could be useful for themes, indeed, but it needs more power than simple equality check:

<txp:etc_query globals="prefs" functions="strnatcmp" query="strnatcmp('{?version}', '4.6')>=0">
	New era
<txp:else />
	Outdated version
</txp:etc_query>

Very interesting tag. Thanks!

And to skin the cat one more time:

<txp:adi_globals name="version" />

<txp:rah_function call="version_compare" version1='<txp:variable name="version" />' version2="4.5.7" operator=">" _is="TRUE">
	<txp:variable name="version" /> is the future
<txp:else />
	<txp:rah_function call="version_compare" version1='<txp:variable name="version" />' version2="4.5.7" operator="<" _is="TRUE">
		<txp:variable name="version" /> is the past
	<txp:else />
		<txp:variable name="version" /> is the present
	</txp:rah_function>
</txp:rah_function>

Damn! How do I get the last word?.. maybe

<txp:etc_query url="http://textpattern.com/" functions="version_compare" globals="prefs"
	query="version_compare(string(//p[@class='versionNumber']), '{?version}', 'le')"
>
	You are on the edge
<txp:else />
	Please upgrade
</txp:etc_query>

Actually, I think that this is a nice example for the power and versatility of the Textpattern system. Not only do plugins seamlessly integrate into the textpattern syntax, but can be combined almost ad libitum, in this example with txp:rah_function. Thereby, an amazingly simple application logic can be generated, which rests upon highly intelligent plugins and would otherwise require much expertise and programming efforts. Theses benefits of Textpattern over competing CMS could be explained more clearly on the Textpattern homepage.
