I generally make a node with a unique headline somewhere, like '@common
code-xyz' that has the function definition:
@common code-xyz
---
def hello():
g.es('hello')
---
Then in my @button:
@button run-hello
---
# load the common code 'library'
pos = g.findNodeAnywhere(c, '@common code-xyz')
exec(g.getScript(c, pos))
# call the code
hello()
---
Hope this helps!
