# Tool to convert a template file (.tpl) into a C++ header
|
|
# file with a const string defining the same template. This string
|
|
# can then be used to create/retrieve a template using
|
|
# Template::StringToTemplate()/StringToTemplateCache() (see template.h).
|
|
#
|
|
# Usage: template-converter <template_name> < infile > outfile
|
|
#
|
|
# template_name is the name of the variable we export. A good choice
|
|
# is to pass in the outfile name. To make that easier, we treat
|
|
# <template_name> as a pathname, and take the basename, strip the
|
|
# suffix if it's .h, and sanitize the rest of the name to be a legal
|
|
# C variable name.
|
|
# MOE:insert # NOTE: See doc/index.html for a general description of Google ctemplate.
