This may just be a lack of experience talking, but I always assumed that when possible it was better to use a commands built in abilities rather than to pipe to a bunch of commands. I wrote a (very simple) script a while back that was meant to pull out a certain error code, and report back what... (4 Replies)

TAGSTYLES
<TMPL_IF var><TMPL_VAR foo></tmpl_if var>
<!-- TMPL_IF var --><!-- TMPL_VAR foo --><!-- /tmpl_if var -->
<%if var %><%= foo %><%/if var %>
Optional tagstyle 'tt':
[%if var %][%= foo %][%/if var %]
ACCESSING VARIABLES
<%= _.foo %>
outputs foo in the cuurent position of the stash and is the same as
<%= foo %>
<%= .config.url %>
goes to root of parameter stash; like $params->{config}->{url}
<%= ..foo %>
goes one level up in stash
<%= list[3].keyname.method %>
acts like: $stash->[3]->{keyname}->method
TAGS
VAR
<%var foo%> or <%= foo%>
IF, IF_DEFINED, UNLESS, ELSIF, ELSE
conditions like in Perl
LOOP, WHILE, EACH
for-loop and while-loop like in Perl.
<%loop cds%><%= __counter__%>. Title: <%= _.title%><%/loop cds%>
<%loop cds join=", " %><%= _.title%><%/loop cds%>
<%while resultset.next%><%= __counter__%>. <%= _.foo %><%/while %>
<%each hashref%><%= __key__ %>=<%= __value__ %><%/each %> (sorted alphanumeric)
<%each hashref sort=alpha %><%= __key__ %>=<%= __value__ %><%/each %> (sorted alphanumeric)

PERL
See section Perl in HTML::Template::Compiled
ATTRIBUTES
Each attribute can be written as
attribute=foo
attribute="some thing"
attribute='some "thing"'
NAME
You can omit the 'name=' here.
<%if var%>var<%elsif name=var2%>var4<%/if%>
Can be used in all tags.
ESCAPE
<%= message escape=html %>
<%= params escape=url %>
<%= params escape=js %>
<%= some_var escape=dump|html%>
Can be used in "VAR"-tags.
DEFAULT
<%= this.var.might_be_undef default="my fault" %>
Can be used in "VAR"-tags.
ALIAS
<%loop cds alias="cd" %><%= cd.title %><%/loop cds %>
Can be used in "LOOP" and "WHILE". Works like "SET_VAR" and is short for
<%loop cds %><%set_var cd value=_ %><%= cd.title %><%/loop cds %>
Useful for nested loops.
SET_VAR
<%set_var myvar value=.another.var %>
<%set_var myvar2 expr="60 * 60 * 24" %>
This creates a variable similar to local() in perl. To use such a var or an alias in includes, you must use "USE_VARS" in the include.
USE_VARS
<!-- recognize myvar and myvar2 as variables not parameter stash -->
<%use_vars myvar,myvar2 %>
myvar: <%= myvar %>
JOIN
<%loop cds join=", " %><%= _.title%><%/loop cds%>
can be used in "LOOP"
BREAK
<%loop cds break="3" %>
<%= _.title%><%if __break__ %>
</%if %>
<%/loop cds%>
Sets "__break__" to 1 every xth loop. Can be used in "LOOP", "WHILE" and "EACH"
