if_version tag?

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?

Re: if_version tag?

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

Re: if_version tag?

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

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	Outdated version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!

Re: if_version tag?

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>
