{{tlg}} (template link, general) is a general template for inserting a template link. It can be used to replace or implement any of the more specific {{tl*}} templates, e.g. {{tl}}, {{tlx}}or {{tlb}}. Parameters are:

  • ​bold=yes​: Boldface the text, like for {{tlb}} and {{tlxb}}
  • ​italic=yes​: Italicizes the parameters, like for {{tlxi}}
  • ​tt=yes​: Use a monospaced font, like for {{tlx}} and {{tlxb}}
  • ​code=yes​: Use the <code>...</code> HTML attribute (usually a monospaced font), like for {{tlc}}
  • ​nolink=yes​: Don't insert a template link, like for {{tlf}}, {{tld}}, and {{tlc}}
  • ​anypage=yes​: Allow linking to arbitrary page (not just template), as with {{tlu}}
  • ​braceinside=yes​: Put braces inside the link, like for {{tn}}
  • ​subst=yes​: Add a ​subst:​ prefix, like for {{tls}}
  • ​alttext=FOO​: Specify alternative surface text for a link, like for {{tla}}
Note
On the source sister projects, en.wikipedia and Meta, X0, X1, X2,..., X9 are sandbox templates for experimentation on involved templates that need be in template space. An auto-cleansing software facility exists that might be used to duplicate the facility on other Sister projects.

Now the expression links to x0 (the spaceship, genetic disease, etc.) rather than Template:x0. Mostly useful for templates in user space.

No reason you can't combine multiple parameter settings.

Can combine named and anonymous parameters ...

{{||সাঁচ:x2|x2]]|one|two}}

... in any order …
{{Tlg|x2|one|tt=yes|two|bold=yes|three}}

{{||সাঁচ:x2|x2]]|one|two|three}}

... even intermixed ...
{{Tlg|x2|one|tt=yes|two|bold=yes|three|italic=yes}}

{{||সাঁচ:x2|x2]]|one|two|three}}

... with many different configurations.
