## About
If you are familiar with the [pfetch](https://github.com/dylanaraps/pfetch)
system information tool by [dylanaraps](https://github.com/dylanaraps), this
does the exact same thing, but with an about _10x faster_ runtime. _pfetch_ is
simple by design with some (but not many) configuration options and a
minimalistic look.
**Supported Platforms:** Linux, Android, macOS, Windows, FreeBSD, NetBSD

## Installation
### Binary
Download a binary from the
[latest release](https://github.com/Gobidev/pfetch-rs/releases/latest).
### Cargo
```sh
cargo install pfetch
```
### Homebrew
```sh
brew install pfetch-rs
```
### AUR
Install the [pfetch-rs](https://aur.archlinux.org/packages/pfetch-rs) or
[pfetch-rs-bin](https://aur.archlinux.org/packages/pfetch-rs-bin) AUR package.
## Performance
Benchmarks performed on an AMD Ryzen 5 3600. Execution time is measured using
[hyperfine](https://github.com/sharkdp/hyperfine) with `-w 4 -m 500 -N` flags
| POSIX `sh` (bash) | 23.7 ± 0.9 | 22.3 | 29.3 |
| POSIX `sh` (dash) | 15.9 ± 0.3 | 15.1 | 18.2 |
| Rust (v2.3.0) | 2.2 ± 0.2 | 1.8 | 3.9 |
_Note: This is with `pacman` and `flatpak` being the only installed package
managers. For more info, see [Improving Performance](#imp_perf)._

### Improving Performance
The by far slowest part of the `pfetch` execution time is counting the installed
packages. For most package managers this is still very fast, but there are some
(currently `nix` and `zypper`) that take ~500ms to report installed packages,
which takes away all performance benefits of the Rust version. If you have one
or more of these installed, you can skip counting them by setting the
`PF_FAST_PKG_COUNT` environment variable.
## Configuration
Like the original `pfetch`, `pfetch-rs` is configured through environment
variables. Your existing config will probably still work, the only difference is
how padding is configured.
If you want to display a custom logo, you will have to download the source code,
make your changes to `./pfetch-extractor/logos.sh` and build the binary with
`cargo b --release`.
```sh
# Which information to display.
# Default: first example below
# Valid: space separated string
#
# OFF by default: shell editor wm de palette
PF_INFO="ascii title os host kernel uptime pkgs memory"
# Example: Only ASCII.
PF_INFO="ascii"
# Example: Only Information.
PF_INFO="title os host kernel uptime pkgs memory"
# A file containing environment variables to source before running pfetch.
# Default: unset
# Valid: A shell script
PF_SOURCE=""
# Separator between info name and info data.
# Default: unset
# Valid: string
PF_SEP=":"
# Enable/Disable colors in output:
# Default: 1
# Valid: 1 (enabled), 0 (disabled)
PF_COLOR=1
# Color of info names:
# Default: unset (auto)
# Valid: 0-9
PF_COL1=4
# Color of info data:
# Default: unset (auto)

PF_COL2=9
# Color of title data:
# Default: unset (auto)
# Valid: 0-9, COL1 (copies COL1 value)
PF_COL3=1
# Alignment paddings (this is different to the original version).
# Default: unset (auto)
# Valid: int
PF_PAD1=""
PF_PAD2=""
PF_PAD3=""
# Which ascii art to use.

# 'HOSTNAME=cool_pc pfetch' to restrict their
# usage solely to 'pfetch'.
# Which user to display.
USER=""
# Which hostname to display.
HOSTNAME=""
# Skip package managers that take "long" to query package count (like nix)
