A C based template engine, with C as the template language.
I.e., create templates with C code embedded in it, that can
be expanded at runtime (eval like capability!).
See tests/ directory. At a basic level, ctpl can be used
as an extended sprintf where the host program's variables
can be interpolated in the template [string] - anything between
the @{ and @} tags. But any valid C code can go into the
template - comments, declarations ...
The _() function does the actual interpolation. There are
convenience macros like NL and TAB to insert newline and
tabs respectively.
There are 3 parts to using ctpl:
Template is any C string, with parts to be expanded under
@{ and @} - there can be many such blocks.
Call ctpl_init() with a buffer that can hold expanded template.
Call ctpl_expand(), passing as arg, template and all the variables/symbols used in the
template (from the host program). This is where ctpl differs from other template engines
which use dynamic/reflective languages!
If the variable is not a basic C data-type, then ctpl_custom_type() call is needed. Also,
the user defined type should be in a separate header file that should be given to ctpl.
Once expanded, the user provided buffer will have expanded string.
ctpl_status() can be used to check if we succeeded or not.
