Multiline functions

It seems that only one way to implement multiline functions exists (fast and clear):

1. Use includes instead of functions;

   #include filename
   

   It’s works like simple text insertion in this place (several includes in different parts of the file are allowed)
2. Use variable replaces with #include (include bonus) file main.cpd:

   τ_max=200MPa
   τ=150MPa
   #include check_stress: τ->σ; τ_max->σ_max
   

   file check_stress.cpd:

   #if σ ≤ σ_max
     '<font color="green">It is all OK ('σ' ≤ 'σ_max')</font>
   #else
     '<font color="red">It is problem ('σ' > 'σ_max')</font>
   #end if
   

   file main.cdp processed like this single file:

   τ_max=200MPa
   τ=150MPa
   #if τ ≤ τ_max
     '<font color="green">It is all OK ('τ' ≤ 'τ_max')</font>
   #else
     '<font color="red">It is problem ('τ' > 'τ_max')</font>
   #end if
   

3. namespaces instead of local variables It’s just an invisible prefixes for variables. Bonus - block #namespace…#namespace end - to make it more automatic

   a=10'       shows a=10
   b=20'       shows b=20
   ns1::a=11'  shows a=11
   a'          shows a=10
   ::a'        shows a=10
   ns1::a'     shows a=11
   b'          shows b=20
   ::b'        shows b=20
   #namespace ns1
     a'        shows a=11
     b'        shows b=20 - if b missing for this namespace search in top namespace
     b=21'     when assigning - use current namespace
     b'        shows b=21
     ::b'      shows b=20
     ns1::a'   shows a=11
     ::a'      shows a=10
   #end namespace
   a'          shows a=10
   b'          shows b=20
   ns1::a'     shows a=11
   ns1::b'     shows b=21
   #namespace ns1
     a'        shows a=11
   #end namespace
   

P.S. Includes is the most wanted feature here. Even if nothing else will be implemented. (it’s solves problems with big file navigation, very nice to extract generated svg images/methods into separate files, it’s partly solves problems with missing string values)

Great! I am glad that it works for you. Probably I can optimize the internal editor to work faster. There were plenty of new features added recently.

Next steps is to fully implement the deg/rad/grad units as discussed. Also, input values embedded in code {1.23}. We need to update the documentation and other resources.

I thhink that the next majour change should be vectors and matrices. They are needed very much to make Calcpad a fully functional math environment.

I will close this issue now as it was generally implemented. If you find anything, you can open a separate issue since this one became too long ad difficult to follow.

It is OK in my version. I will send it to you soon.
