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: set locale

I want my date & time printed according my locale settings.
This commit enables that

Added CPU iowait to README

slstatus: add cpu_iowait

This commit introduces the cpu_iowait item, this is the percentage
of cpu time spent waiting on disks. High numbers typically indicate
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.

Deleted slstatus.png as it is unnecessary

slstatus load_avg format string

Added IPv6 address function

- Renamed "ip" function to "ipv4"
- Added "ipv6" function
- Adjusted README and config.def.h accordingly

sexy config.def.h table

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.

Removed #define for update interval

Debugging #define, especially in mathematical constructs is very
difficult. The performance overhead of static const int is negligible.

Updated LICENSE

Extended Ali H. Fardan contribution dates

keyboard_indicators: fix segfault when -s is specified

Fixed possible NULL-deref and removed unnecessary XOpenDisplay()

- Added a check for the return value of XOpenDisplay() in main().
  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.

Refactor build system

Formatting commit :(

I know formatting commits suck... And I try to avoid them.

But this commit was absolutely necessary... The coding style in this
program was not ok and not the same over the whole program.

The commit is hard to read, but this is what I changed:
- Tabs for indentation instead of spaces
- Same style over the whole program (suckless style)

simplified ram function

Easier info function names

All the info function names started with "get_", which I removed to make
it easier for the user to configure the program to its needs.
Additionally I renamed some functions (e.g. get_ram_usage) to better
names, making it easier to extend the program with ram usage / total
functions.

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

Fix some memory leaks

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

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

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

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()

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.
