# amalgamate.py - Amalgamate C source and header files

`amalgamate.py` aims to make it easy to use SQLite-style C source and header
|
|
amalgamation in projects.
|
|
|
|
For more information, please refer to: http://sqlite.org/amalgamation.html
|
|
|
|
## Here be dragons
|
|
|
|
`amalgamate.py` is quite dumb, it only knows the bare minimum about C code
|
|
required in order to be able to handle trivial include directives. It can
|
|
produce weird results for unexpected code.
|
|
|
|
Things to be aware of:
|
|
|
|
`amalgamate.py` will not handle complex include directives correctly:
|
|
|
|
#define HEADER_PATH "path/to/header.h"
|
|
#include HEADER_PATH
|
|
|
|
In the above example, `path/to/header.h` will not be included in the
|
|
amalgamation (HEADER_PATH is never expanded).
|
|
|
|
`amalgamate.py` makes the assumption that each source and header file which
|
|
is not empty will end in a new-line character, which is not immediately
|
|
preceded by a backslash character (see 5.1.1.2p1.2 of ISO C99).
|
|
|
|
`amalgamate.py` should be usable with C++ code, but raw string literals from
|
|
C++11 will definitely cause problems:
|
|
|
|
R"delimiter(Terrible raw \ data " #include <sneaky.hpp>)delimiter"
|
|
R"delimiter(Terrible raw \ data " escaping)delimiter"
|
|
|
|
In the examples above, `amalgamate.py` will stop parsing the raw string literal
|
|
when it encounters the first quotation mark, which will produce unexpected
|
|
results.
|
|
|
|
## Installing amalgamate.py
|
|
|
|
Python v.2.7.0 or higher is required.
|
|
|
|
`amalgamate.py` can be tested and installed using the following commands:
|
|
|
|
./test.sh && sudo -k cp ./amalgamate.py /usr/local/bin/
|
|
|
|
## Using amalgamate.py
|
|
|
|
amalgamate.py [-v] -c path/to/config.json -s path/to/source/dir \
|
|
[-p path/to/prologue.(c|h)]
|
|
|
|
* The `-c, --config` option should specify the path to a JSON config file which
|
|
lists the source files, include paths and where to write the resulting
|
|
amalgamation. Have a look at `test/source.c.json` and `test/include.h.json`
|
|
to see two examples.
|
|
|
|
* The `-s, --source` option should specify the path to the source directory.
|
|
This is useful for supporting separate source and build directories.
|
|
|
|
* The `-p, --prologue` option should specify the path to a file which will be
|
|
added to the beginning of the amalgamation. It is optional.
