CLIgen is a Command-Line Interface generator written by Olof Hagsand.
Well, actually it is not really a generator, since it does not generate code for CLI:s. Instead, it builds and interprets datastructures (a parse-tree) which a library (libcligen) interprets in runtime. It is fast and efficient and helps you develop CLI:s easier. You enter a CLI syntax either in a text file, you write callback functions where you call the right library routines. The callback functions add the semantics, that is, what the commands in the CLI are supposed to do.
Presentations and tutorial is found on the CLIgen project page
CLIgen is not a system in itself, you need to build your own 'backend'. We have started another project: 'clixon' which is actually a whole system where you load dynamic frontend and backend modules CLIXON project page and CLIXON github. Clixon provides a system, with embedded database, commit semantics, YANG and NETCONF interface, etc. CLIgen is a part of clixon.
The source code here is built and installed using:
configure;
make;
sudo make install.
The source builds a single library. If you build applications, you should include cligen.h and link with the library.
There are several example applications:
- cligen_hello Simplest possible. Just builds a 'hello world' greeting by in-line C
- cligen_file Read a syntax specification from file. You must supply the file.
- cligen_tutorial Samples of techniques used in cligen_tutorial.pdf.
