Description
I have recently found myself with cause to parse some ill-formed partial JSON -- a library that we are incrementally converting to Jsonnet was originally parsed by the C preprocessor, and had files like this:
main.jh:
{
"unit_1": {
#include "unit_1.jh"
},
"unit_2": {
#include "unit_2.jh
},
...
}
unit_1.jh:
"out": {
... data ...
}
I'd like to be able to load a unit_1.jh directly into Jsonnet without invoking an external pass. Obviously, I can't hand it to import, since it's ill-formed. importstr can load it so that I can do extra work on it, but once I have a string, I can't convert it to an object. Really, I'd like to be able to do something like:
eval ("{" + importstr "unit_1.jh" + "}")
Or, even better,
local importjh(f) = eval("{" + importstr f + "}")
though that would require changes along the lines of #196, too.
This is closely related to #460, but maybe more general. One key difference is that #460 wants to be "safe"; in this case, "everybody knows" that any time you type "eval", you deserve whatever happens next 😄 We intend to use this only on trusted JSON databases.
