NotAShelf	ca76a6e1bd	chore: format with rustfmt nightly ... Signed-off-by: NotAShelf <raf@notashelf.dev> Change-Id: I9c9e4e010b09d37f0e0994a5407f3ce56a6a6964	2025-11-17 19:18:39 +03:00
NotAShelf	f4f3385ff7	various: fix clippy warnings ... - Adds proper documentation comments with `# Errors` sections for all functions returning `Result` - `cast_precision_loss` on `u64` -> `f64` for disk sizes is acceptable since disk sizes won't exceed f64's precision limit in practice. Thus, we can suppress those. - `cast_sign_loss` and `cast_possible_truncation` on the percentage calculation is safe since percentages are always 0-100. Once again, it's safe to suppress.

NotAShelf	9d8905354e	expand comment strings ... 80 chars is good. Signed-off-by: NotAShelf <raf@notashelf.dev> Change-Id: I6a6a696460754266ff5810a73f98ce9e6eb0c35b	2025-08-04 21:04:32 +03:00

ErrorNoInternet	c139026704	refactor: clean up a few things ... I've decided to keep lazy_static for now as std::sync::LazyLock seems to have a slightly bigger impact on binary size.	2025-04-15 03:46:15 -04:00
NotAShelf	e9aa9a2bbe	uptime: get rid of nix crate	2025-03-30 22:33:16 +03:00
NotAShelf	d0f88b179c	further optimize uptime retrival ... Try and minimize expensive operations (e.g., divisions and allocations) to hopefully get a *consistent* measurable performance improvement. In my testing this brings the get_current function duration from > 1.2600 µs to < 1.2400 µs.	2025-01-26 01:06:02 +03:00
NotAShelf	592fb58474	get rid of color_eyre ... Should never have added it. Annoyingly long compile times for no reason...	2025-01-26 00:57:02 +03:00
SomeEmptyBox	4fff13a51f	Update memory icon (#15) ... Makes memory icon bigger by using CPU icon from Nerdfonts instead of the memory icon.	2024-12-19 17:02:32 +00:00
NotAShelf	4b7836d572	append newline to write_all output ... Fixes a small bug that resulted in terminal artifacts. My bad, gang.	2024-12-19 19:13:16 +03:00
NotAShelf	fd18e9d244	release: conditionally improve performance for get_os_pretty_name ... It is difficult to get completely accurate benchmarks, given how small the numbers we are dealing with are, but this seems to point at an overall trend of *slightly* faster execution. The change minimizes unnecessary memory allocations and string manipulations, to help ensure more performant line reading and immediate return upon finding the PRETTY_NAME without additional, redundant operations.	2024-12-19 18:30:33 +03:00
NotAShelf	065216af7c	colors: respect NO_COLOR spec ... Microfetch will now respect the NO_COLOR environment variable if it has been passed to the program. The performance overhead of this operation is almost none. In addition, the main function has been updated to lock stdout.	2024-12-19 17:21:56 +03:00
NotAShelf	3960b37089	faster release parsing ... Around 20% faster when you think about it, but results vary because of hardware race conditions.	2024-12-09 17:30:57 +03:00
raf	8f5bfcbd05	implement --version for checking program version (#10)	2024-10-29 16:45:55 +00:00
vali	f1e8ca8773	add benchmarking for individual functions (#9) ... * add benchmarking * update README to include benchmarking of individual functions * README: formatting * README: add link to Criterion's getting_started * shell.nix: add gnuplot Since Criterion.rs uses gnuplot to generate nice plots, add it to the shell. * Cargo.toml: fixed microfetch binary name * benchmark.rs: fix benchmark function's name * Update README.md --------- Co-authored-by: raf <raf@notashelf.dev>	2024-08-15 17:43:39 +00:00
Ryan	907112f2d1	micro optimizations (#8) ... * perf: break early after parsing required meminfo Also a match statement for compiler magic. * perf: pre-allocate strings when reading files * refactor: remove duplicate .to_string() * perf: try to print everything in one syscall println! sends a syscall for each line. * perf: get rid of duplicate uname syscall * perf: simplify first letter capitalization * refactor: directly use key in match statement	2024-08-15 10:32:02 +00:00
Ryan	1cf4f754ac	parse /proc/meminfo for memory usage (#7) ... * fix: calculate memory usage via /proc/meminfo * refactor: move sysinfo call into get_current No longer used by anything but uptime.	2024-08-15 08:14:27 +00:00

NotAShelf	927f6077b4	store printed fields in a struct ... Shut up, clippy.	2024-08-05 11:33:42 +03:00
Ryan	13903539b7	perf: use nix::sys::utsname::uname for less syscalls (#2) ... Instead of reading multiple files to get the `sysname`, `release`, and `machine` name, use the `nix::sys::utsname::uname` function which sends a single uname syscall instead. This increases performance and portability. From my observations, there are ~10 less syscalls.	2024-08-05 08:08:25 +00:00
