Should address issue #630.
|
|
|
|
Fixes #166.
|
|
|
|
Every quantity is now read in its own function and Maybe and
pattern matching is used for dealing with absent files.
On top of that all units should be fixed now.
|
|
|
|
Fixes #624
|
|
Add <$> for parsing content of file.

Closes #208
|
|
|
|
Instead of searching for a fixed set of files and directories (numbered
0-9), which would miss anything above 9, it now searches the relevant
directories for files matching the right pattern, regardless of number.
Fixes #616.

For start cirrus please use:
https://cirrus-ci.org/guide/quick-start/
choose public repositories plan and add only xmobar as observed by cirrus.
Also here is addes small fix for dividing by zero when cpu usage is calculated
|
|
Using this library allows us to receive swap info which is more
similar with result of command swapinfo.
|
|
In FreeBSD /proc/pid/stat is missing we should use for top procstat
library.
|
|
|
|
We should make better split os specify code for FreeBSD and Linux.
Idea comes from @liskin.
|
|
in freebsd swap info is available by sysctl
|
|
In freebsd /sys/class/net is absent so we should use sysctl for
obtaining info about stats of network.
For parsing if_data struct we could use a "Foreign.Storable"
|
|
In freebsd /proc/memoryinfo is absent so we should use sysctl for
obtaining info about stats of memory.

* A queue reader for xmobar using `TQueue a` from `stm`.
This is a flexible and performat solution for sharing
data between arbitrary haskell and xmobar.
* I am not sure if I did the haddocks correctly.

The automatically derived read instance expects the type to be given in
record syntax; this is not what most users want. In order to simply
specify the type via
Run NotmuchMail "mail" [MailItem "name" "" "tag:unread"] 3000
we have to write our own Read instance.

The existing support for the coretemp kernel driver only works with
Intel CPUs.
This commit extends support for temperature monitoring to AMD CPUs.
k10temp is a kernel driver for monitoring the temperature of AMD
processors. It supports everything from AMD's 10h (Opteron/Athlon)
family of processors to the latest 19h (Zen 3) family.
Reference: https://www.kernel.org/doc/html/latest/hwmon/k10temp.html
The meaning of the various temperatures made available has changed over
the years and only `Tctl` is available on processors prior to the 17h
family.
Labels for these temperatures are present but as Tctl and Tdie do not
contain a number I could not find a way to use these as
`checkedDataRetrieval` expects an integer label.
It is a PCI device and so an address needs to be supplied as part of the
configuration.
Example configuration:
`Run K10Temp "0000:00:18.3" ["--template", "T: <Tdie>C | <Tccd1>C"] 60`

This plugin checks for new mail, provided that this mail is indexed by
notmuch. As mail that was tagged is moved from the new directory to
cur, the 'Mail' plugin (and its variants) won't work for such mail.

Introducing the throttling unfortunately has a negative side-effect: it
delays all stdin processing, including EOF detection, which can cause
confusion the previous commit tries to fix.
The only benefit of the throttling is to prevent 100% CPU usage when a
lot of garbage is provided on xmobar stdin. We still don't know where
that garbage comes from in https://github.com/jaor/xmobar/issues/438, or
rather why there's more than a handful of lines of such garbage. @psibi
has since fixed his setup to not produce that garbage, and no one else
ever reported such a problem, so it's probably safe to ignore it for
now.
Should anyone ever encounter that again, feel free to ping me, even in
the middle of the night, to help debug this.

This corrects a misleading comment "EOF check is necessary for certain
systems" which was added without complete understanding of the root
cause of #442. That issue was in fact caused by old xmobars not being
terminated on early EOF, and is thus necessary on _all_ systems that
rely on EOF to terminate old xmobar before starting a new one. (To
trigger the bug, one additionally needs to close the xmobar pipe before
sending any input to it, which is unusual, but incorrectly configured
xmonad might trigger that.)
Furthermore, this fixes another execution path that could lead to xmobar
not being terminated on EOF:
`echo -e '\xff' | xmobar -c '[Run StdinReader]' -t '%StdinReader%'`
would terminate the StdinReader thread upon catching the "invalid
argument (invalid byte sequence)" so there'd be no thread to detect the
subsequent EOF and xmobar would get stuck.
Additionally, I believe that terminating either the thread or the entire
xmobar upon receiving a single miscoded byte isn't desirable, as this
might be an intermittent issue and another input line can be perfectly
okay. Therefore I suggest that the original issue @psibi was trying to
fix by b7a3d6745817 is worked around by introducing a throttling delay
instead of terminating the thread, as I assume that exceptions other
than async and EOF are recoverable.
