Re-implement `eval` as a regular builtin I did not realize builtins could safely call into the parser and inject jobs during execution. This is much cleaner than hacking around the required shape of a plain_statement. 2019-04-12 19:53:08 +08:00			`// Prototypes for executing builtin_eval function.`

Let's make src/ easier to grok, move builins to src/builtins + No functional change here, just renames and #include changes. + CMake can't have slashes in the target names. I'm suspciious of that weird machinery for test, but I made it work. + A couple of builtins did not include their own headers, that is no longer the case. 2021-11-10 09:07:15 +08:00			`#include "../maybe.h"`
Change builtins to return maybe_t<int> instead of int 2020-07-19 01:25:43 +08:00

Make arguments to builtins const Prior to this change, builtins would take their arguments as `wchar_t `. This implies that the order of the arguments may be changed (which is true, `wgetopter` does so) but also that the strings themselves may be changed, which no builtin should do. Switch them all to take `const wchar_t ` instead: now the arguments may be rearranged but their contents may no longer be modified. 2021-02-14 10:41:09 +08:00			`maybe_t<int> builtin_eval(parser_t &parser, io_streams_t &streams, const wchar_t **argv);`
