[html-template-devel] external format in an included template printer
by Igor Plekhov 09 Mar '07

09 Mar '07

Function #'create-template-printer has :external-format key parameter which is used when opening a file with a template to be filled. But if that file <tmpl_include>s some other file, than :external-format supplied is not used when opening the second file as it should be. In #'create-template-printer-aux function #'create-template-printer function is called with an included file only. May be it is worth to make a special variable like *hunchentoot-default-external-format* for default value of :external-format parameter for #'create-template-printer function. In SBCL special variable sb-impl::*default-external-format* can be binded to an external-format required as a workaround. -- Registered Linux User #124759

[html-template-devel] tmpl_equal needed ?
by Vamsee Kanakala 26 Dec '06

26 Dec '06

Hi, I think html-template really needs a templ_equal tag. I am trying to pre-select an option inside a select tag, based on parameters passed. Since the option tags are also being generated through a loop, I think there is no way I can do this unless I can have some comparison mechanism within the template. Kindly correct me if I'm wrong. Thanks, Vamsee.

[html-template-devel] Proposed new feature for HTML-TEMPLATE
by Marijn Haverbeke 12 Dec '06

12 Dec '06

[I sent this to Edi earlier, but it seems to have been ignored. I just saw that there is actually a mailing list for this project, so I'm hoping that sending it to the correct place will generate a bit more response.] > For a personal project I extended your HTML-TEMPLATE library with an > extra TMPL tag.

Here is how it works: > > Support for the TMPL_CALL tag is added.

[html-template-devel] Escaping of HTML in Templates
by Cam Desautels 21 Oct '06

21 Oct '06

Forgive me if I am missing something here, but given that HTML-TEMPLATE is supposed to be agnostic to exactly what type of content I am putting in a template, why is it escaping my HTML? Is this not a bug? I'm running 0.7.0 on SBCL 0.9.16. (html-template:fill-and-print-template "<p></p>" '(:foo "This <em>is</em> HTML")) --> <p>This <em>is</em> HTML</p> Thanks. -- Cameron Desautels <camdez(a)gmail.com>

No, I can't see it, because I didn't see a backtrace yet. Did you make sure that after changing the external format the template was really read again, i.e. did you clear the template cache? Besides, my /guess/ is that the error is signaled when you're writing to the Araneida stream - something one could probably see in the backtrace. Try to create a test case without Araneida, so you can be sure it doesn't affect the result.

[html-template-devel] Fwd: Re: Re: Question about html-template
by Jonathon McKitrick 29 Sep '06

Here is the footer for the html file I am serving as a template: <div> Copyright (c) 2006 Reed Larkey Group Inc.   •   Website designed by <a href="http://www.bartosz.co.nr/">Bartosz Brzezinski</a> </div> Note the copyright symbol and the bullet. here is the code from the :get handler under araneida: (fill-and-print-template (pathname (concatenate 'string (araneida::static-file-pathname handler) (araneida::static-file-default-name handler))) nil :stream (request-stream request) :external-format :utf-8) )) It's plain and simple for now. No template vars, etc. I looked up 'with-open-file' and then 'open' to figure out what external-format types are valid, but the hyperspec said this was implementation specific. ATM, sbcl.org is down as well. I'm running sbcl 0.9.17 on an Intel Mac. > Did you try the EXTERNAL-FORMAT keyword argument of > CREATE-TEMPLATE-PRINTER and FILL-AND-PRINT-TEMPLATE? I added that to the example code above, but when I get the backtrace, you can see that EXTERNAL-FORMAT was LATIN-1, even though in 'create-template-printer' the same keyword arg is UTF-8, UNICODE, or whatever other value I pass in. -- Jonathon McKitrick Independent Software Consultant

And maybe a backtrace. And maybe information about the Lisp implementation you're using. And maybe a self-contained test case which describes how one can reproduce the error, maybe with a small example file. http://www.chiark.greenend.org.uk/~sgtatham/bugs.html > Do you have any suggestions on how I can solve this?

[html-template-devel] New version 0.6.0
by Edi Weitz 14 Sep '06

14 Sep '06

ChangeLog: Version 0.6.0 2006-09-14 Changed default for *VALUE-ACCESS-FUNCTION* Added *STRING-MODIFIER* Added ESCAPE-xxx functions (from CL-WHO) Fixed docs for hyperdoc support General documentation enhancements Fixed test.lisp w.r.t. *FORMAT-NON-STRINGS* Download: http://weitz.de/files/html-template.tar.gz Note that some of the changes introduced in 0.5.0 and 0.6.0 make the library slightly incompatible with earlier versions. As there have been no bug fixes since 0.4.0, it is safe to stay with this version if you have code which you don't want to change. Cheers, Edi.
