This is cdecl, the C gibberish translator. This version has been enhanced by ridiculous_fish to support Apple's blocks syntax.

Original README follows:

        Cdecl version 2.5

Cdecl is a program which will turn English-like phrases such as "declare foo as array 5 of pointer to function returning int" into C declarations such as "int (*foo[5])()". It can also translate the C into the pseudo- English. And it handles typecasts, too. Plus C++. And in this version it has command line editing and history with the GNU readline library.

The files in this distribution are:

cdecl.c The cdecl source code. cdlex.l The lex source for the cdecl lexer. cdgram.y The yacc source for the cdecl parser. cdecl.1 The cdecl man page. c++decl.1 The c++decl man page (really just cdecl.1). testset A script to test the operation of cdecl. testset++ A script to test the operation of c++decl. Makefile The makefile to build and install cdecl. README See file README for description of this file.

If you have the GNU readline library and its headers in readline/*.h and termcap then you can install cdecl by "make" followed by "make install". To compile without readline and termcap, you must edit the Makefile and remove -DUSE_READLINE from the CFLAGS and -lreadline and -ltermcap from the LIBS. You will, unfortunately, lose the command line editing, history, and keyword completion. By default cdecl installs in /usr/bin, but this is configurable in the Makefile.

I debated with myself whether to provide a precompiled libreadline.a and associated headers with the cdecl distribution, however that would have made the tar file much bigger, so I have decided not to. If you think I should, or you would like me to send you readline, please get in touch with me at [email protected] You can find the source for readline in the bash distribution on or on, or wherever fine GNU source isn't sold.

You should also be able to find a ready-to-run ELF binary of cdecl in the same place you got this from. It should be on in the directory /pub/Linux/devel/lang/c/, or on any of the many sunsite mirrors. My three favorites are,, and

You may well be wondering what the status of cdecl is. So am I. It was twice posted to comp.sources.unix, but neither edition carried any mention of copyright. This version is derived from the second edition. I have no reason to believe there are any limitations on its use, and strongly believe it to be in the Public Domain. GNU readline is, of course, covered by the GNU General Public License.

I was inspired to port cdecl to Linux as there was no version of it available in the various Linux software archives that I am aware of. The addition of GNU readline support seemed like a logical extension of the program. Be warned, however, that linking with readline more than doubles the size of the program. Those whose main concern is space might wish to build a version without readline.
