Accessing lib functions without braces

Hi all,
Is there a way to access/execute user-defined precompiled library functions from the interactive cint interface WITHOUT using braces? For example, if I have the following function in my file myfuncs.h: void add(int a, int b); // displays result a+b and create a customized interpreter "mycint" with makecint that embeds the above function, I would like to invoke add() from the interactive environment without the braces, i.e. I would like to do - ======= > > mycint (..... interactive interface started....) mycint> add(456, 123) 579 mycint> quit > ======= Is there a way to do the above? Currently, I can only invoke add() with the braces as follows: ======= > mycint (..... interactive interface started....) mycint> {add(456, 123);} 579 mycint> quit > ======== That seems rather painful. It's very easy to miss a brace or the semicolon! All the examples in the demo directory for makecint invoke user-defined archived library functions from other files and not from the interactive environment. I've had some success by faking it with G__init_cint(), G__calc() etc., but that fails as soon as the arguments of the called functions get somewhat complicated or have white spaces. And I also don't have the actual interactive interpreter environment anymore, e.g., I can't invoke the previous call(s) using the up-arrow on the keyboard. Thanks for any pointers. Veena |

Hi Veena,
you can switch to CINT's other prompt mode by defining the proprocessor macro -DG__ROOT when building cint. I will make that a bit more accessible soon. Let me know if that does what you need.

Hi Axel,
I see no difference with -DG__ROOT. I still need the semicolon and the braces to call my library functions. Thanks.

Hi Veena,
uh, right, I'm terribly sorry for wasting your time rebuilding CINT - I actually should have realized that :-/ The easiest solution is to set INPUTMODE in configure to "c++". I will add a switch for that at some point (it's now on my to-do list). Cheers, Axel. On 2008-01-30 17:00, Veena Gondhalekar wrote: > Hi Axel, > > I see no difference with -DG__ROOT.
