Uni,
I see you do not use prefixes any more. Does that mean, you are considering the GSL as the primary source of generic SMath functions? IMHO that would be sensible, as GSL seems to be the most vital and most free library among the ones you wrapped so far. However, I have no idea about performance issues.

Functions that are not yet implemented not have a prefix. When I add a function in the plug-in, I add a prefix to it. All the functions in this library will have the same or similar names which given in their description.

For example: gsl_sf_bessel_J0() -> gslsfJ0(), gsl_sf_airy_Ai() -> gslsfAi(), ...

I'll ask Andrey to implement the namespace for functions. This option may be enabled and disabled as the description of the region. In this case, you can specify the function names without the prefix.

I am not sure that I understand correctly, what the namespace for functions concept is meant to be.
Is that something like local aliasing?
Is that a by-region setting?
What is the visualization concept?

I'd expect something like switching on aliasing (and perhaps enabling of the plugin) by a separate statement "with("GLS" ) or with("Matlab" ). This could be
deactivated later in the same sheet by a function without() in a traceable manner.

BTW, how about including a plugin hint in the description string of the functions. I had to search the forum in order to find out what plugin provides the erf() function (Davide, sorry for my leaking memory). Not a big deal for me, but would help to correctly direct user feedback.

I think it only works for the document in text form. It is unlikely that this method will be useful in our case.

We have one example of namespace support. Not necessarily indicate the selected space, but the user should be able to select it. We can assign a hot key to display the namespace for the selected function.

Ok, it is a Mathcad concept (I was not aware of that).

The example with m as units and m as variable does not really convince me. By math standards, these items should be distinguished by type face (italic for variables, upright for units or other items that are not supposed to change. SMath has this the other way around, but at least clearly indicates the difference. Thus, the unit name space tag is the apostrophe ' in front of the name.

There is another "namespace" then in SMath, the absolute variables with ~ as tag (which would be fine to represent matrix/vector values).

An option for getting along without new features would be to leave the prefixes in the names and to provide generic names pointing to the most appropriate function from whatever plugin it may come or even to provide wrapper functions like Findroot() to choose from what is available.

The ordinary ("mortal" ) user hardly wants to choose from 20 ode solvers or from 10 nonlinear solvers.

Installing this plugin causing forced close on Arch Linux + Mono.
After forced close you cannot be able to open Smath again unless manually deleting the plugin.

Because the plugin is not compatible with Linux + Mono:

This use of the library is beyond the scope of the forum. I will try to create a simple example, but you still need to read the original documentation to use the library.
