Antoine Pitrou commented on ARROW-6323:
---------------------------------------
It sounds fine to handle it in R. If we want we can add some handling for that
in C++ too, but that doesn't sound urgent.
> [R] Expand file paths when passing to readers
> ---------------------------------------------
>
> Key: ARROW-6323
> URL: https://issues.apache.org/jira/browse/ARROW-6323
> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Neal Richardson
> Assignee: Neal Richardson
> Priority: Major
> Fix For: 0.15.0
>
>
> All file paths in R are wrapped in {{fs::path_abs()}}, which handles relative
> paths, but it doesn't expand {{~}}, so this fails:
> {code:java}
> > df <- read_parquet("~/Downloads/demofile.parquet")
> Error in io___MemoryMappedFile__Open(fs::path_abs(path), mode) :
> IOError: Failed to open local file '~/Downloads/demofile.parquet', error:
> No such file or directory
> {code}
> This is fixed by using {{fs::path_real()}} instead.
> Should this be properly handled in C++ though? cc [~pitrou]
