* radical re-formatting 2/3: Fix blocksdrkhsh2022-10-281-14/+8
| | | | | | Fixes coding style. Formatting commits suck, incoherent coding style sucks more. https://suckless.org/coding_style/
* radical re-formatting 0/3: Alphabetic headersdrkhsh2022-10-281-2/+2
| | | | | | | | Except stated otherwise in comment. Fixes coding style. Formatting commits suck, incoherent coding style sucks more. https://suckless.org/coding_style/
* various: Put paths into defines to avoid line wrapsdrkhsh2022-10-281-3/+3
| | | | | | Long, wrapped, multi-line if statements suck to read. This fixes readability in the worst places by packing format strings for paths into defines.
* do not rely on obsolete featureNRK2022-10-261-6/+6
| | | | | | | | | | function prototype with unspecified argument is obsolete since c99. additionally some of these function which don't take any argument were being called with a `const char *` arg, which is UB. fix both these issues by declararing ALL the components to accept a `const char *`, and name the arg "unused" if it's meant to be ignored.
* components/*.c: include slstatus.hNRK2022-10-261-0/+1
| | | | | this gives the compiler a chance to check weather the prototype and definiton matches or not, which would catch issues like 3c47701.
* cpu_perc: Check for division by zeroIngo Feinerer2019-02-161-18/+27

* Simplify format specifiers for uintmax_tAaron Marcher2018-07-071-5/+2
|
* cpu_freq: Simplify with E-notationAaron Marcher2018-07-071-1/+1
| | | | Thanks to the FRIGN
* cpu_freq: Change to 64 bit integersAaron Marcher2018-07-071-2/+3
| | | | Remove unnecessary cast to size_t
* Change uint64_t to uintmax_tAaron Marcher2018-07-071-4/+4

* cpu: Use uint64_t on OpenBSDAaron Marcher2018-07-071-2/+3
|
* Clean up header includesAaron Marcher2018-05-301-1/+0
| | | | | - Remove <errno.h> because related functions are in util.c now - Remove corresponding <string.h> if not used otherwise
* Merge fmt_human_2 and fmt_human_10 to one functionAaron Marcher2018-05-211-2/+2
| | | | Now only one function, fmt_human, takes an additional argument "base".
* Remove units from numbersAaron Marcher2018-05-211-4/+4
| | | | | | | | | | This is a first step to decouple formatting from information because of two reasons: 1. The components should only gather and return the values by design 2. Fine grained user control should be a focus Scaling will be implemented in a different way in a later commit.
* Remove unnecessary "valid" variable in cpu_percAaron Marcher2018-05-201-6/+2
|
* Implement scaling for cpu_freqAaron Marcher2018-05-191-5/+13
|
* Add the percent sign to *_perc functionsAaron Marcher2018-05-191-2/+2
| | | | Units should be added to the corresponding numbers
* Use %d instead of accidentally %iAaron Marcher2018-05-181-1/+1
|
* Add warn() and die()Laslo Hunhold2018-05-181-2/+2
| | | | | | | | | | | Given slstatus is a tool that runs in the background, most likely run from .xinitrc, it's important to prepend the name of the tool to error messages so it becomes clear where the error is coming from. To make this much more consistent, this commit adds warn() and die() utility functions consistent with other suckless projects and adapts all calls to fprintf(stderr, *) to the warn() and die() functions, greatly increasing the readability of the code.
* Cast CPU percentage to int and fix indenationAaron Marcher2018-05-141-11/+11
|
* cpu: Simplify functionsAaron Marcher2018-05-071-16/+14
|
* Fix coding styleAaron Marcher2018-05-061-4/+3
| | | | | | | | | - Use block for single statement ifs - Keep lines to reasonable length (current debate as to reasonable) - When functions return -1 for error test against 0 not -1 - Do not indent cases another level - Do not test against NULL and 0 explicitly - Use tabs for indentation, use spaces for alignment
* Remove cpu_iowaitAaron Marcher2018-05-061-25/+0
| | | | | | The third value from load_avg (idle) gives us almost the same information as cpu_iowait. Plus OpenBSD does not offer an iowait value as Linux and thus the corresponding function would not be portable.
* cpu_perc: Documentation and readbility improvementsAaron Marcher2018-05-061-9/+9
|
* cpu_perc: Port to OpenBSDAaron Marcher2018-05-061-0/+35
| | | | | In OpenBSD the CPU usage in percent is now computed using KERN_CPTIME sysctl.
* Use indentation to increase readabilityLaslo Hunhold2018-05-011-66/+70
| | | | | | | | | | | Granted, this style is definitely not common, but for the short utility-functions of this program it's just the right choice. This provides great flexibility, such that in the long run, it will be possible to also share code between the OS-implementations. This also keeps the state-keeping at a minimum and makes it clearer which functions are implemented on which OS without having to jiggle around with too many files in the process.
* Revert component-splitLaslo Hunhold2018-05-011-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this reverts the commits from 92ab9ef52ebcb097add97d9f78e67ad1c1d6a6ec up to d42870d6ca7fb587b38f8cf6d6821ae33a53a696. After heavy consideration, the component split has more disadvantages than advantages, especially given there will be utility-functions sharing quite a lot of code that would then need to be duplicated, as it does not fit into the util.c due to its speciality. One big advantage of the component-wise build is readability, and without doubt, this was achieved here. This point will be addressed with a different approach that will be visible in the upcoming commits. One big disadvantage of the component build is the fact that it introduces state to the build process which is not necessary. Before its introduction, the only influencing factors where the system-defines __linux__ and __OpenBSD__. With the components, we are also relying on the output of uname(1). Additionally, if the os.mk is not present, make gives the output $ make Makefile:5: os.mk: No such file or directory make: *** No rule to make target 'os.mk'. Stop. This could easily be fixed by providing some sort of meta-rule for this file, however, it indicates the problem we have here, and this entire statefulness will heavily complicate packaging of this tool and makes the build process much more complex than it actually has to be.

* cpu_freq: Port to OpenBSDAaron Marcher2018-04-301-1/+24
| | | | In OpenBSD CPU frequency gets fetched using sysctl now.
* More robust preprocessor switchesAaron Marcher2018-03-211-1/+1
| | | | | Replace #ifdef with #if defined() and #elif with #elif defined() as it should only test if it is defined or not.
* Build Linux-only functions only on LinuxAaron Marcher2018-03-181-0/+2

* Move components into dedicated subdirectoryLaslo Hunhold2017-09-241-0/+63
This brings us a lot more tidiness.
