Write templates in C preprocessor language.
./cppt -D'TITLE="cppt_demo_#1"' -D'USERS(u)=u("Jesus",2015)u("Alice",17)u("Max",-1)' <example/example.cppt
The output is a chunk of HTML:
<!doctype html>
<html><head>
<title>cppt_demo_#1</title>
<meta name="description" content="Example page">
</head><body>
<h1>Users:</h1>
<table class="users" id="my-table">
<tr><td>Jesus</td><td>2015</td></tr>
<tr><td>Alice</td><td>17</td></tr>
<tr><td>Max</td><td>-1</td></tr>
</table>
</body></html>
And here is what the template itself looks like:
#define html doctype t("html", "", head body)
#define doctype "<!doctype html>\n"
#define head t("head", "", title description "\n")
#define title "\n" t("title", "", TITLE)
#define description "\n" t1("meta", \
a("name", "description") \
a("content", "Example page"))
#define body t("body", "", h1 table)
#define h1 "\n" t("h1", "", "Users:")
#define table "\n" t("table", \
a("class", "users") a("id", "my-table"), \
"\n" USERS(table_row)) "\n"
#define table_row(user, age) t("tr", "", \
t("td", "", user) t("td", "", #age)) "\n"
Cppt template files must #define the html symbol as a string - the result of applying the template.
A few primitives are built in.
t(tag, attributes, content)Creates a tag with given attributes and content.
t1(tag, attributes)Creates a void (a.k.a. self-closing) tag with no content.
a(key, value)Creates an attribute. Can be combined with other attributes to form the attributes string containing all of them.
Usage: cppt [-D<definition>]... <TEMPLATE
Definitions have to be in exactly the same format as described in GCC(1).
Note: to pass a sequence of objects, you create a definition that accepts another macro, applies it to each object in a sequence and then concatenates the results. See the example.
