for caching some generated data, I’d like to save a nested Lua
table to a file, and load it later.
I found http://lua-users.org/wiki/SaveTableToFile
Is there already something (better) in ConTeXt? I'd assume, since
the functionality is needed for tuc files?
table.tofile("my_file.lua",my_table)
Thank you, I overlooked that in cld-mkiv, since I was looking for
table.save (which was mentioned in a thread about Ecir Baff’s art).
And for reading context.runfile, right? What does it better than
Lua’s dofile?
You don't tell what you want to do with the file
Load and process the table as if it was created directly.
table.save("my_file.lua",my_table)
What’s the difference between table.tofile and table.save? tofile is
documented in cld-mkiv* while save is not. table.save is also not
mentioned in the Lua reference manual. Where does it come from?
my_table = tabel.load("my_file.lua")
wrt runfiles benefits:
- finding the file
- checking it
- reporting on it
Great, thank you!
*) BTW, cld-mkiv speaks of "luafilesystem" while the library is called
"lfs".
(It’s strange, while in Python I just try everything, in Lua I feel the
need to check every step… Maybe it’s because I want my code to be "best
practice" because it might become part of documentation… And of course I
still lack the same experience that I have in Python.)
