===== Library Header file Snippet =====


{{ :snippets:c:libheadersnippet.png?300|}}

This is an absurd, yet extremely useful snippet I use often.  It is for creating a library header file in an existing file.  This would be best as a [[http://www.geany.org/manual/current/index.html#file-templates|File Template]] but since the filename is important, it won't work like that.  First open up your [[http://www.geany.org/manual/current/index.html#user-definable-snippets|Snippets]] file and copy & paste the following under the **[Special]** group:

<code>

</code>

Of course you might want to use another License, so modify the above accordingly, though it's a pain to make it all on one line with the comment symbols and such.  Now copy & paste the following under the **[C]** group:

<code>
_h=/*\n * {filename}\n * \n * Copyright {year} {developer} <{mail}>\n * \n%license% * \n */\n\n#ifndef {command:python -c "print '{filename}'.split('.')[0].upper()"}_H\n#define {command:python -c "print '{filename}'.split('.')[0].upper()"}_H\n#ifdef __cplusplus\nextern "C" {\n#endif\n\n\n%cursor%\n\n\n#ifdef __cplusplus\n} /* extern "C" */\n#endif\n#endif /* {command:python -c "print '{filename}'.split('.')[0].upper()"}_H */
</code>

Now create a new file and save it with the correct filename (ex. foo.h), then in the blank file type '_h' and press TAB.  Now you have all the boilerplate for your new library header file.  Note that the snippet above requires you have [[http://www.python.org/|Python]] on your system.
