- Change the main! proc_macro to a bin! macro_rules macro.
- Reexport uucore_procs from uucore
- Make utils to not import uucore_procs directly
- Remove the `syn` dependency and don't parse proc_macro input (hopefully for faster compile times)
Fix a bug in which "\r\n" was not being replaced with "\n" in text mode
on Windows. This would happen only if one call to `write()` ended with a
"\r" character and the next call to `write()` started with a "\n"
character. This commit fixes the bug by buffering a "\r" character if it
appears at the end of one call to `write()` and only writing if the
first character in the next call to `write()` is *not* a "\n" character.
Fixes issue #2681.
Create a `DigestWriter` struct that implements `Write` by passing bytes
directly to `Digest::input()`, so that `hashsum` can use
`std::io::copy()`. Using `std::io::copy()` eliminates some boilerplate
code around reading and writing bytes. And defining `DigestWriter` makes
it easier to add a `#[cfg(windows)]` guard around the Windows-specific
replacement of "\r\n" with "\n".
Unify the usage of macros `safe_unwrap` and `crash_if_err` that are
identical to each other except for the assumption of a default error
code. Use the more generic `crash_if_err` so that `safe_unwrap` is now
obsolete and can be removed.
Remove a copy operation of the input buffer being read for digest when
reading in text mode on Windows. Previously, the code was copying the
buffer to a completely new `Vec`, replacing "\r\n" with "\n". Instead,
the code now scans for the indices at which each "\r\n" occurs in the
input buffer and inputs into the digest only the characters before the
"\r" and after it.
* hashsum: support --check for var. length outputs
Add the ability for `hashsum --check` to work with algorithms with
variable output length. Previously, the program would terminate with an
error due to constructing an invalid regular expression.
* fixup! hashsum: support --check for var. length outputs
This makes clap wrap the help text according to the terminal width,
which improves readability for terminal widths < 120 chars,
because clap defaults to a width of 120 chars without this feature.
- refactor internal version specifications to be ">=M.m.p" (where M.m.p is *already published*)
## [why]
Loosening internal version dependencies decreases the coupling between packages such
that packages can be published in a looser order. It allows the packages to be version
updated and published in tandem (ie, by using `cargo workspace ...`). Once published,
the internal versions can then be updated (again, to an *already published* package
version), as needed.
* hashsum: switch from getopts to clap
Additionally, slightly refactor. This commit will be the first of
a series of commits refactoring (at the very least) `hashsum`.
