Question

我从perl 使用 TT, 并试图插入模板和处理一个变量, 该变量本身包含 TT 指令。

所以,在剧本中,我写着Smth,就像:

$var{descr} = "[% pid = 1; INSERT plink.par %]";

TT模板(收到var):

[% BLOCK parsedDescr %]
[% descr %]
[% END %]
<p>[% INCLUDE parsedDescr %]

And I m expecting pid variable being set to "1", and plink.par file inserted. But instead I get on my html page exactly contents of the variable descr:

[% pid = 1; INSERT plink.par %]

即,该变量不由TT处理。

我如何让TT处理它的内容?

http://template-toolkit.org/docs/manual/Filters.html#section_eval_evaltt" rel=“noreferrer”>eval过滤器 :

<p>[% descr | eval %]

从链接的 manpage 中 :

The eval filter evaluates the block as template text, processing any directives embedded within it. This allows template variables to contain template fragments, or for some method to be provided for returning template fragments from an external source such as a database, which can then be processed in the template as required.
