NAME

ecppc - compiler for ecpp

SYNOPSIS

ecppc [-bhszvtM] [-s-] [-o filename] [-n name] [-m mimetype] [--mimetypes filename] [-I dir] filename
ecppc -bb filename...

DESCRIPTION

Ecppc is the compiler for the ecpp-language. Ecpp is a template-language, which lets the user embed C++-code into HTML for use in tntnet (8). Ecppc generates a C++-class from a ecpp-template. It can also compile binary data into a C++-class, which makes it possible to integrate them in a tntnet-application.

OPTIONS

-b

This enables binary-mode. Ecppc does not look for ecpp-tags, but creates a class, which just copies the data

-bb

This enables multi-binary-mode. Every binary-file has some overhead, when packed into a tntnet-application. This overhead can be quite significant, when binary-files are small, like small icons in a web application. To reduce this overhead, multiple binaries can be packed into a single class, which removes the per-binary overhead completely.
When the component is called, it uses the path-info-parameter (request.getPathInfo()) from the request, to decide, which binary to send. If no filename matches the path-info, processing is declined. The binaries need not be of same mime-type, since the mime-type is looked automatically from the mime-database by file-extension of the source-file.

-h

Generate a separate header-file. Without this option, the class-declaration and -definition are put both into a single output-file.

-I dir

Search include-files in directory. This option can be passed multiple times. All specified directories are searched in turn for include-files.

-L

Disable generation of #line-directives

-m mimetype

Set mimetype of output. This is the mimetype, sent by the component to the browser in the Content-Type-header. Without this parameter the mimetype is looked up from the mime-database of your system using the file-extension of the source-file.

--mimetypes file

Read mimetypes from file (default: /etc/mime.types).

-M

This disables normal processing and prints just the ecpp-dependencies from this component. The output can be included into a Makefile. Ecpp-dependencies are introduces by the <%include>-tag.

-n name

Set the classname of the component. Normally this is derived from the source-file-name by removing the .ecpp-extension.

-o filename

Write the generated file to the specified file instead of deriving the filename from the source-file-name. The outputfilename is normally the source-file where the extension is replaced by .cpp.

-s

Generate singleton. Normally ecppc decides automatically, if the template is suitable for a singleton. This option force ecppc to generate a singleton.

-s-

Do not generate a singleton.

-v

Enable verbose mode. This prints additional information about the processing on the standard-output.

-z

Compress the data in the component. Compressed data is automatically decopressed on first use. This reduces the code-size, but slightly slows down the first call of the component.
