* ps: Add command `ps` * pidof: Add some basic arguments and flags * ps: Introduce new dependencies. Introduce `uu_pgrep` for processing processes, and introduce `prettytable-rs` for output. * ps: Finish command infrastructure. * pgrep: Implemented `Hash` trait for `ProcessInformation`. * misc: Introduce `nix` crate * pgrep: Rename `TerminalType` to `Teletype` * ps: Use `Vec<Rc<RefCell<_>>>` for mutable data. * misc: Fix conflict * misc: Fix fmt * pgrep: Revert refactoring. * ps: Add `basic_collector` * ps: Introduce `picker` mod to do data picking. * ps: Implemented user defined data picking * ps: Collect and apply header mapping and use `Vec` instead of `LinkedList` * ps: Add license header * ps: Apply suggestions * ps: Implemented logic of `-o` * ps: Implement basic function. * ps: Remove empty line of output * ps: Implemented nullable format parser. And also introduce `thiserror` crate. * ps: Implemented `-o` (`--format`) * ps: Add license header for `parser.rs` * misc: Apply modifications from upstream * ps: Implemented code of `time` * ps: Fix check failure * ps: Fix build failure on Windows * ps: Enable tests for another *NIX system. * ps: Revert tests support for *NIX platform. It looks like it's very difficult to implement the ps command on *NIX platforms as portable, as it's only portable if you have a proc pseudo-fs. In other words, the current design only even supports Linux. - FreeBSD's proc pseudo-fs is not automounted. - macOS does not have a proc fs, it use sysctl instead. * ps: Refactor mappings to `mapping.rs` * ps: Clean code * misc: Bump version of `nix` crate. * ps: Rewrite document and optimize code. * ps: Clean TODO and add TODO Remove TODO in `mapping.rs` and add TODO in `collector.rs` * ps: Allow multiple occurrences of the same code. * ps: Fix default codes' display * ps: Use `Result` instead of `Option` in `parser.rs` * ps: Remove duplicate elements of `proc_infos` * ps: Implemented sorting But only implemented the basic usage: sorting by pid. * ps: Rename functions in `sorting.rs` - Rename `sorting` to `sort` - Rename `default_sort` to `sort_by_pid` --------- Co-authored-by: Sylvestre Ledru <sylvestre@debian.org>
