In Erlang how can I compile a module from within a module?

Question

I have tried :

c(module_name).

: but this only works from the shell, and gives an error when I try to run it from within a module.

Answer 1

If you want exactly that behaviour, c:c(module_name) will call the same function called by the shell. I would hesitate to put code that calls user_default ( c ) functions in production code, so you might want to look at the source for the function and replicate it in your own code so you don't get bitten by a behaviour change in a future erlang release.

Answer 2

您可能希望查看编译模块和特定的compile：file / 2函数。
