Re: Alphabetical list of articles in a section
BTW, we could add first to available escape values. Or even consider integer values as substring length:
<txp:variable name="hello" value="welcome" />
<txp:variable name="hello" escape="3" /> <!-- outputs 'wel' -->
<txp:variable name="hello" escape="-2" /> <!-- outputs 'me' or 'lcome' or 'welco'? -->Offline
Re: Alphabetical list of articles in a section
Oooh interesting. If we’re going that way and it’s not going to clash with anything else…
<txp:variable name="hello" value="welcome" />
<txp:variable name="hello" escape="3" /> <!-- outputs 'wel' -->
<txp:variable name="hello" escape="3,4" /> <!-- outputs 'lcom'? -->
<txp:variable name="hello" escape="-2" /> <!-- outputs 'me'? -->
<txp:variable name="hello" escape="5,-2" /> <!-- outputs 'co'? -->
<txp:variable name="hello" escape="-5,4" /> <!-- outputs 'lcom'? -->The only thing with using the from,count syntax is that it differs from PHP’s substr() insofar as it starts from 1 and not 0, for consistency with the single count syntax. That might confuse programmers at first, but everyone else should get it.
EDIT: not really sure if ‘escape’ is the right terminology though. If we’re doing this, shouldn’t we introduce a new global attribute? I’d suggest expanding trim (since we’re trimming the text by a number of characters) except it’s currently used to trim alphanumerics, and an integer is a valid character you might want to strip off.

Oleg, that is some superb tag-fu you are displaying. Splendid.
I’m trying hard to understand – taking notes along with the URL of the thread to test and analyse once I am past the first strong cold of the year (ginger tea with the last of the yuzu).

Yep, escape will not do since comma is used as separator there. We could adopt 1%%9 syntax used in custom fields filter, and trim suits better indeed. But I’m not sure we need it in such a generality: extracting/removing 3 first letters can be useful on plugins/themes sites, but other cases look exotic.

Ah of course. If you think escape with an integer just for removing everything but the given N letters is worthwhile, by all means stick it in.
