John Ericson	6c861b9c51	Factor out lookupExecutable and other PATH improvments ... This ended up motivating a good deal of other infra improvements in order to get Windows right: - `OsString` to complement `std::filesystem::path` - env var code for working with the underlying `OsString`s - Rename `PATHNG_LITERAL` to `OS_STR` - `NativePathTrait` renamed to `OsPathTrait`, given a character template parameter until #9205 is complete. Split `tests.cc` matching split of `util.{cc,hh}` last year. Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>	2024-08-07 18:12:58 -04:00
John Ericson	ef2d10f7e7	Clean up env var logic in preparation for Windows ... It's a little weird we don't check the return status for these, but changing that would introduce risk so I did not.

John Ericson	02fa20622f	Start factoring out Unix assumptions ... This splits files and adds new identifiers in preperation for supporting windows, but no Windows-specific code is actually added yet. Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>	2024-04-02 14:43:38 -04:00
