NYAGOS - The Nihongo Yet Another GOing Shell .

English / Japanese

Since 4.1 .

NYAGOS 4.0 has the problem that a panic sometimes occurs because multi-goroutines call only one Lua-instance.

On NYAGOS 4.1, I tryied to prevent from panic and to make stable by creating Lua-instances for each lua-call and not allowing multi-goroutines use same one.

But, it has the new problem that the functions assigned to nyagos[] , can not see variables set on .nyagos including themselves. Because Lua-instances have their own variable-areas not seen by other instances.

To share data between the different Lua-instance, On 4.1, the values assigned on the global table nyagos[] and share[] are linked to Go's memory. They are able to be accessed by all Lua-instance.

It breaks the compatibility on Lua scripts. To let Lua scripts for 4.0 run on 4.1, these modifing are required.

• Value assigned to global variable should be assigned to share[].
  • Values and functions in share[] are able to be access from all lua-instances.
  • nyagos.exe can find modifying the member of share[] and nyagos[] only.
    • OK: share.foo = { '1','2','3' }
    • NG: share.foo[1] = 'x'
    • OK: local t=share.foo ; t[1] = 'x' ; share.foo = t
  • Do not assign closure to nyagos.alias[] ! The code in the function can not access the bind variables.
