size_t may not be enough, use 64 bit integers

Add Ian Remmler to LICENSE

Add flexible formatting to keyboard_indicators.

Updated for style.

uptime: unification of the uptime function for linux/openbsd

wifi: fixed disconnected wifi status on openbsd

Clean up header includes

 - Remove <errno.h> because related functions are in util.c now
 - Remove corresponding <string.h> if not used otherwise

Update LICENSE for Quentin

Flush the output stream instead of arbitrarily disabling buffering

This is (arguably) more elegant and it matches Xlib output logic.
Also use puts instead of printf as we don't do formating there.

Don't explicitly list each component-target

I made a mistake while reading the Posix spec. In fact, the implicit
prerequisite imposed by the .c.o-rule is evaluated as expected, even if
the .c is not given in the target rule.

This partially reverts 0efd64ffaa04715eff9c834c437562952c4531cd.

swap: removed unused include

Refactor swap.c to use getline() instead of buf-filling

This drops a lot of code and even though we are using a common function,
the specification of only the needed things keeps it very efficient and
even more efficient in memory and time than the previous solution.

Update LICENSE for Tobias

Fix object order and stop using a GNU make idiom

Explicitly list component-objects in the Makefile

There was a long tinkering process at farbfeld about this, but the sad
truth is that it's the only way to make the Makefile truly portable.
Listing it just as

   $(COM:=.o): config.mk $(REQ:=.h)

omits the dependency on the c-file itself, which incurs that strictly
speaking the object file is not depending on the source file, which is
nonsense.

You don't see strictly Posix compliant Makefiles around very often and
most use nasty GNU-extensions everywhere. It is a good idea to go ahead
as a fitting example and show how to write them portably.

Use E-notation for large powers of 10

Revert "Add basic backlight percentage support"

On OpenBSD the backlight percentage cannot be retrieved in a simple way.
The only two solutions we are aware of for now are:

 - reading from /dev/ttyC0: which isn't possible without changing
 permissions or running slstatus as root
 - linking against xcb-xrandr: which is bloat and does not work in every
 case appearently

This reverts commit 37724ac2c3f496f4736223d0d8e5d8fecb933590 for now.

ram: fixed int overflow on pagetok macro

Refactor keymap.c

 - Get rid of camel-casing
 - Don't use all-caps for variable names
 - use LEN()-macro
 - use strncmp() rather than strstr() for prefix-checking
 - clean up the tokenizer-loop and don't use copies
 - make the loop more readable by separating different breaking
   conditions
 - stricter error-checking and cleanup
 - store the layout directly with bprintf rather than having
   a separate buffer

Refactor snprintf-usage in util.c

keymap: Add braces for for loop

Add keymap to README

Add Michael Buch to LICENSE

Add keymap component

Adding a new keymap component that will
indicate the current keyboard layout (language)
and variant if any was set. I use the
standard X11 XKB APIs to retrieve and parse
the xkb_symbols set with setxkbmap.

Remove o-flag as it is redundant

Even if we extend the flag to be an n-flag with a numerical input, we
already have other Unix-tools to take care of us much more flexibly,
e.g. with head(1) you can easily get the first 10 outputs with

	slstatus -s | head -n 10,

but also e.g. discard the first one and then get the consecutive 10
outputs.

For the X11-root-window-name, you can limit the runtime with timeout(1)
or a comparable solution.

This reverts commit fa8b939990ed0648f99b0cbeba4efed807160db3.

Check printf() for output errors

This way cases like

	$ slstatus -s > /dev/full

are properly caught and the program terminated with the proper return
code.

netspeeds: Fix indentation

Add basic backlight percentage support

At the moment linux only, but will add support for OpenBSD as well.

Change to fmt_human in netspeeds on OpenBSD

Thanks to Hiltjo

swap.c: Refactor getstats() and its usage

Add a return value so we are able to check any errors and actually fail
when there has been a critical error instead of carrying on uselessly.

Refactor fmt_human() and fix a bug

It is not necessary to copy memory or anything. Just keep a pointer to
the active prefix-array and assign the length of the arrays to a
variable.

Make the code more readable by using a switch, be more strict when an
invalid base is passed to it and fix a small oversight in the bottom of
the code where the base 1024 was forgotten to generalized.

Merge fmt_human_2 and fmt_human_10 to one function

Now only one function, fmt_human, takes an additional argument "base".

Remove fmt from load_avgs for consistency

In a later commit something like that will be enabled for every
component

Add option to output only once and exit

battery_remaining: check for division by zero

battery_remaining: Change float to double

battery: Minor coding style fixes

- Line length
- Spacing and indentation
- No explicit checks for NULL

Increase readability for load_uvmexp return

Remove units from numbers

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.

swap_perc: check for division by zero on obsd too

swap_perc: check for division by zero

Add David Demelier to LICENSE

Support energy_now/power_now in battery_remaining

On some laptops (mostly thinkpads), the remaining time may be
expressed in µWh using energy_now and power_now files rather than µAh
for charge_now and current_now.

Add pick function to conditionally select appropriate one.

ip: fixed memory leak

free the interface list before returning from the function

Check return value of pclose()

Refactor ram.c

Make temp more readable on Linux

Refactor entropy.c

Remove initialization to 0 for static vars

Remove unnecessary "valid" variable in cpu_perc

Add unit to temperature

Implement scaling for cpu_freq

Implement fmt_human_2() and fmt_human_10()

These functions take the raw number and a unit and automatically
print it out "scaled down" to a proper SI-prefix, for powers of 2
and 10 respectively.

Apply them to the 2-power cases and keep the 10-power for a later
commit.

Add the percent sign to *_perc functions

Units should be added to the corresponding numbers

Increase precision in netspeeds.c

First dividing by interval before multiplying with 1000 decreases the
precision by +-(interval - 1) * 1000, as interval arithmetic always
applies the Gauß-function to the result.

This is not necessary and simply reordering the operations mitigates
this.

Implement esnprintf() and make formatted calls more efficient

Within the components, snprintf() was unchecked and had inefficient
calls in some places.
We implement esnprintf() that does all the dirty laundry for us
and use it exclusively now.

Simplify ipv* functions

Use `int` for flags

Revert aac29e2 as it is nonsense

Set {r,t}xbytes 0 before incrementing them on OBSD

Missing assignment for last commit

Unify and simplify netspeed logic and types

readable.

uptime: Format function is static

battery: Move out struct as common code

implemented openbsd netspeed functions

implemented the netspeed functionality for openbsd.
furthermore the static keyword was removed of the interval variable in
config.def.h for usage as extern variable.

Add netspeeds to config.def.h

Add network speed functions

Implement fmt_scaled for ram_* functions

Fix ram_free for Linux

Implement fmt_scaled for swap_* functions

Port battery_remaining to Linux

Additionally unify the format of battery_state and uptime

Fix memory leak

battery: fixed remaining time on connected AC

when an AC is connected apm_info shows a non-valid value for remaining
minutes. it was decided that in that case the function should return an
empty string.

Fix indentation

Tabs for indentation, spaces for alignment

Add battery_remaining function on OpenBSD

Implementation of a battery_remaining function which returns the
remaining battery time in HH:MM format. Linux function still needs
implementation.
Move common code to load_apm_power_info

Add warn() and die()

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.

Audit slstatus.c

 1) Remove setlocale() (locales are harmful and any 'issues' shall
    be fixed in different ways that are expected).
 2) Disable buffering on stdout with setbuf() rather than flushing
    it each time.
 3) Make error messages more consistent.
 4) Add error checks where applicable.
 5) Make code a bit more readable where res is assigned.
 6) Use XFlush() rather than XSync() (we don't need to wait for the
    XServer to react, which could lead to long hangs on our side).

Properly handle *snprintf() errors

Posix guarantees that the resulting string is null-terminated, even if
we have an overflow. Instead of doing what has already been done,
properly warn when there has been an error or overflow, so the user can
do something about it.

Remove UNUSED macro

Use variables named unused instead which is simpler

Mark unused parameters, fix compiler warnings

wifi: Fix order and add missing header

<sys/select.h> is needed before <net80211/ieee80211_ioctl.h> on OpenBSD

fflush(stdout) to print line by line if stdout is not a tty

To reproduce the issue:

then it would print only when the stdout buffer is full, by block
of multiple lines.

fflush() makes sure the line is printed at every loop iteration

Add josuah to LICENSE

include <sys/time.h> before <sys/sensors.h> for time struct timeval

- 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_iowait

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 improvements

cpu_perc: Port to OpenBSD

In OpenBSD the CPU usage in percent is now computed using KERN_CPTIME
sysctl.

swap_*: Port to OpenBSD

battery: Remove full indicator

Remove battery_power for various reasons

- Battery power cannot be easily gatherable via apm(4)
- IMHO it does not represent essential information

Tweak build system a little bit

Be consistent with brackets and add a comment for OpenBSD to make it
clearer what the actual intent of the uncommented line is.

In the Makefile, add a dependency of slstatus.o from config.mk.

battery_perc: Port to OpenBSD

components/swap.c | move duplicated code to separate function

Use indentation to increase readability

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-split

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.

Get rid of err.h as it is not portable

Replace warn() and warnx() with fprintf() and add <stdio.h> where
necessary.

Remove ALSA dependency from README

ALSA is not a dependency anymore as we use /dev/mixer. The corresponding
notice about PulseAudio is thus not necessary too.

More robust preprocessor switches

Return actual percentage for wifi_perc()

Implement basic percentage calculation for wifi_perc. With this
commit, the function returns correct percentage, since the max
of what /proc/net/wireless returns is 70.

Move components into dedicated subdirectory

This brings us a lot more tidiness.

Get rid of HDR variable

The HDR variable is used for general purpose headers, which are not
given in this project. arg.h and config.h are only needed for
slstatus.c, not every component $(COM:=.c).

This also fixes a problem introduced in
e04a3853643df1c98a451969d515d8850f138bcc, where config.h is pulled into
the tarball.

Simplify Makefile

Fix missing config.h in Makefile

Added LICENSE statements to all source files

Properly declare buf as extern and fix all unused-warnings

Rewrite Makefile to accomodate file split

Split into multiple files

For multiple reasons the program is now split:
- Make future porting to OpenBSD easier
- Assign header includes to individiual functions
- Make future program extensions easier
- Recompile only changed parts

Add blank line after setlocale

setlocale() has to be separated from the signal handling.

slstatus: add cpu_iowait

This commit introduces the cpu_iowait item, this is the percentage

that your system is not responsive due to disk IO.
This commit also avoid sleeping inside the cpu_perc and cpu_iowait
functions: waiting in either one implies lost info for the other.

Fix a little logic error

Add pscanf()

This reduces a lot of equivalent code to one function call.

Refactor main()

We remove the hack with the sleep and global "delay"-variable and use a
monotonic clock to derive the desired monotonic properties of the tool.
Inside each function that demands a personal delay we can then just do a
nanosleep() and be done with it.
It's a shame that timespec is so ugly to work with, but there's really
no way to make it more beautiful. However, at this cost though we
finally can set the interval times in milliseconds and not only just
seconds.

We remove setlocale(), because nothing good ever came out of this
function.

Besides that we have some more code refactoring, especially in the
argument loop which saves us a bit of complexity.

Simplify signal handling a bit

Remove unnecessary prototypes

Remove unnecessary blank lines after license-notice

Fix man page .Os field

Added Makefile target for distribution tarballs.

Fixed man page path

According to the FHS, /usr/local/share/man is the correct man page path
in this projects's case. Set this to default in config.mk.

slstatus != dmenu lol

Removed #define for unknown_str

Debugging #define is very difficult. The performance overhead of static const
char is negligible.

  This fixes a possible NULL-deref.
- Removed unnsecessary XOpenDisplay and XCloseDisplay from
  keyboard_indicators(). The ones in main() are sufficent.

Add and use LEN() macro

Refactor battery_state()

Reformatted LICENSE to fit 75 character width

Print usage() when we are left with arguments

Reduce -o | -n to -s

What we really want is to either output to WM_NAME or stdout. If we want
just one single line, we do slstatus | head -n 1.

Remove d- and v-flags

d-flag: There's no need for that, use the &-operator or fork+exec in a
        non-shell-context. In the latter case you get the PID for free.
v-flag: If you want to find out which version of a package is installed,
        consult your package manager. That's his job.

Convert slstatus.1 to mandoc, simplify it and remove -h

We also change the semantics of -v to only return the version
information.
There is now no need for usage() to exit with anything other than 1.

initial commit

Initial commit

fixed some memory leaks

Fixed broken wifi
Fixed indentation
Removed trailig white spaces

Changed RAM calculation formula.

Former : MemTotal - MemAvailable
New : (MemTotal - MemFree) - (Buffers + Cached)

Fixed small buffer in get_datetime()

The buffer being hardcoded to 19 (the size expected from the default time format),
strftime() would fail on any format returning a longer buffer.
Changed it from 19 to 64 to accomodate longer formats.

return n/a instead of exiting if a specific value cannot be read

add config checks on startup for better error handling

add update_interval

add a short sleep to reduce load

make config.h target depending on config.def.h

simplify smprintf by using vasprintf

Fixed locale defaulting to English

Changed get_datetime() a bit so it respects the user-configured locale (to use time formats with strings for days, months etc.)

Same commit as last time, except it merges.

Add diskusage support

add support to show used disk for a given mountpoint

Fix some memory leaks

use warn[x]() instead of long fprintf()s

used ccat() from concat.h for string concatenation

fixed some mistakes

what kind of weed is that?

bringed back the old config.mk

bringed back the old config.mk

bringed back the loop

imported a new vol_perc() function, this should fix #12 (UNTESTED)

added a tool for resetting the status bar && worked around some issues && removed the makefile (we need a better one)

config.mk cleanup

added daemonization support

removed UPDATE_INTERVAL, it is neat to have it but removing it is a tradeoff worth making, because the clock would act weird if this used to work with cpu_perc().

removed setstatus() && simplified main()

NOTREACHED comment

simplified gid()

simplified uid() and fixed username()

removed unnecessary typecast and added more comments

removed unneeded headers

opened the file before the path concatenates, what an idiot

forgot to give entropy() some candy too

slow down boy! you opened the file too early!

removed vol function from the default config file

got rid of conditional assignments && improved the error messages to output more info && added bound checks for fscanf() in hostname() (a dirty hack) && fixed a bug or two && some tiny style corrections

used a different implementation of smprintf() imported from dwmstatus

worked around the buffer overrun in smprintf()

removed heap dependency in datetime() and simplified the function

FIXME: buffer overflow warning

removed a misplaced ';'

used constant string literals && remote initialization to  in battery_perc() && trying to fix possible buffer overflow

grammar correction

removing typecasts for pcm_mixer cause more issues than before

typofix && another update

another update to README

README update

removed unnecessary typecasts (might be a reason for snd_mixer_selem_get_playback_volume_range bug

status_string can hold 4096 bytes now

fixed compiler warnings in a better way

corrected the time format

rm .config.h.swp

fixed the code, works now

Added myself to CONTRIBUTORS.md by drkh5h's request

(void)ed the prototypes

set local function as static

-Wextra

the code describes itself, there is no need to write stories in /* */

braces are unneeded for one-liner if()/while()

added bounds checking via secure strl*() routines

fixed (hopefully) the vol_perc() function

fixed cpu_perc() stupidity && added some useful comment for drkh5h

malloc sucks, you know?

* != **

minor improvements and memory leak fix

Merge branch 'master' of https://github.com/drkh5h/slstatus

subtraction is unneeded

improved hostname()

variable initialization is back

simplified run_command()

several changes

hostname: use POSIX routine to get hostname rather than reading from procfs

vol_perc: return zero if the value of max is set to zero

get rid of unused variable (silly gcc did not report that error)

vol_perc: Return "mute" when mixer is muted

This feature was originally removed as part of 52d19f9.

swap: Print UNKNOWN_STR if no swap is allocated

Update README.md

Edit config.def.h function descriptions

Add functions for measuring swap

Add "uname -r" functionality

Merge branch 'master' into master

fix TODO markdown syntax && update

add braces to single statements so drkhsh doesn't be upset

usage(): return success if -h is called && print more appropriate usage, opts can't be all called at the same time, that's why a separator is required

another TODO update

TODO update

homepage update

extern/concat.h: don't segfault if count == 0

whhops, my bad

wifi_essid: add boundary check && prevent the use of direct string literal as a format string in snprintf()

don't allow the use of perc if uninitialized

remove misleading comment

get rid of set_status() since it's only used once

allow the use of %* symbols in UNKNOWN_STR

add extra error tests to swap_*() && fix bytes_read bug

swap_*(): add more error tests

fix delay in a cleaner way

remove newlines from warn() in swap_*(), those functions already print a newline after printing string stderr

inititalize run_command()'s buf to UNKNOWN_STR by default

remove newline character from run_command() output accurately

strtok() has no effect on buf && fgets() should have the full buffer length

whhops

remove unused strlcpy() and reduce the size of output buffer

Merge branch 'master' into master

add vol_perc notes, add braces to singleline statements

refactor vol_perc to not depend on alsa libraries

Fixed out of boundary write on long lines.

The terminating nul character ('\0') could be written outside the boundary of
the buffer which is used to read characters. If "sizeof(buffer)" characters
are read, the resulting value must not be used as index, because that's an off
by one.

Read sizeof(buffer)-1 bytes instead.

On success, fgets always terminates the result.

If fgets succeeds, then the resulting char array is always
terminated by a '\0'. No need to keep extra space, therefore
sizeof(buf) is the correct argument.

Print unknown_str in case of error

func can return NULL in case of error, but no checking is done when
printing, and unknown_str wasn't being used anywhere.
