Does this code still work? putEnv("key", "value")
assert getEnv("key") == "value"
Because 11 years ago when I wrote the code, it didn't and I had to come up with the |
yes, i just double-checked; if that didn't work nothing would; more importantly, it's covered in the tests, see tosenv.nim which has increased coverage compared to before this PR (c,cpp,js,vm + threads + more testing) EDIT: #18530 (which was merged last week) is also an ingredient that makes this work, by avoiding having to hold on to the strings by using setenv instead of putenv. |

getEnv+ friends gives SIGSEGV or wrong results; osenv should not try to keep track ofenvironment#18533the 1st commit is squashed from #18535 and keeps the author's name
note
code to support empty values on windows (
putEnv("foo", "")) is inspired from facebook/folly@5d8ca09, see also https://github.com/facebook/folly/blob/master/folly/portability/Stdlib.cppthis is the best approach I found after extensive research; it allows having same semantics across backends (c,cpp,js,vm) and os's (osx, linux, windows)
future work
envPairs(via an intermediate seq, like for walkFiles iterator etc)=> tracked in envPairs works in vm, nims #18615
