2021-10-19add cirrus freebsd test (#580)Michał Zielonka
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
2021-10-17start using kvm library from bsd for receiving swapinfoMichal Zielonka
Using this library allows us to receive swap info which is more similar with result of command swapinfo.
2021-10-16add top for freebsd procMichal Zielonka
In FreeBSD /proc/pid/stat is missing we should use for top procstat library.
2021-10-08try to add build action for freebsd + uptime plugin splitMichal Zielonka
2021-10-08try to reorganize modules per osMichal Zielonka
We should make better split os specify code for FreeBSD and Linux. Idea comes from @liskin.
2021-10-07add support swap info for freebsdMichal Zielonka
in freebsd swap info is available by sysctl
2021-10-07Add freebsd support for net monitor plugin.Michal Zielonka
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"
2021-10-04add reading memory specific for freebsdMichal Zielonka
In freebsd /proc/memoryinfo is absent so we should use sysctl for obtaining info about stats of memory.
2021-09-14Add the QueueReader plugin.Guy Gastineau
* 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.

2021-05-24NotmuchMail: Manually implement Read instanceslotThe
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. Related: https://github.com/jaor/xmobar/issues/547

2021-05-19Add k10temp pluginSam Kirby
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`

2020-11-29Add new plugin: NotmuchMailslotThe
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.

2020-11-19StdinReader: Remove throttling on exceptionTomas Janousek
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. Fixes: 7759df11f746 ("StdinReader: Improve exception handling") Fixes: b7a3d6745817 ("Avoid busy looping by not catching all exceptions")
2020-11-19StdinReader: Improve exception handlingTomas Janousek
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.

2020-11-13Optimize Date plugin again (refresh timezone only once a minute)Tomas Janousek
This makes the Date plugin approximately twice as fast, and makes xmobar up to about 5–10 % faster if Date is the only active plugin. (If more expensive plugins like Network or MultiCpu are used, it doesn't make any measurable difference.) Micro-benchmark results on my HW: Date Benchmarks/Date mean 2.833 μs ( +- 16.08 ns ) Date Benchmarks/DateZonedTime mean 5.020 μs ( +- 32.91 ns ) Date Benchmarks/DateWithTimeZone mean 2.827 μs ( +- 20.52 ns ) (DateZonedTime is the original implementation and DateWithTimeZone is the implementation we had since 0.34 which never refreshes timezone.) Real-life measurements (done overnight on an idle laptop, with all measured xmobars running in parallel to ensure comparable conditions; xmobars configured to only display date and with rate 10 — once per second): $ time timeout 6h xmobar .xmobarrc-DateZonedTime real 360m0,010s user 0m9,867s sys 0m4,644s (9.867 + 4.644) / (360 * 60) = 0.000672 $ time timeout 6h xmobar .xmobarrc-Date real 360m0,008s user 0m9,535s sys 0m4,327s (9.535 + 4.327) / (360 * 60) = 0.000642 $ time timeout 6h xmobar .xmobarrc-Date-10m real 360m0,010s user 0m9,780s sys 0m4,215s (9.780 + 4.215) / (360 * 60) = 0.000648 $ time timeout 6h xmobar .xmobarrc-DateWithTimeZone real 360m0,006s user 0m9,658s sys 0m4,166s (9.658 + 4.166) / (360 * 60) = 0.000640 (.xmobarrc-Date-10m is the proposed implementation, but with timezone refresh every 10 minutes instead of every 1 minute) Interpretation of these results: * refreshing xmobar with just date takes around 650 μs * that is xmobar with just date uses around 0.065 % of CPU time * refreshing timezone takes additional cca 30 μs When we only refresh timezone once a minute, these 30 μs become 0.5 μs amortized, and that should be acceptable to even the most dedicated perfectionist :-) Fixes: a58e32f7c8af ("Revert "Optimize date plugin"") Fixes: 878db3908060 ("Optimize date plugin") Co-authored-by: Sibi Prabakaran <sibi@psibi.in>
2020-11-02Revert "Optimize date plugin"ivanbrennan
This reverts commit 878db39080607ba476ba8d8f547ad28259efb6a9. That commit optimized the date plugin by avoiding calling getTimeZone on each execution, instead calling it just once upon startup and reusing that zone. As a result, the time zone will not be updated dynamically, e.g. when shifting in or out of daylight savings time. I noticed this after my local time zone had shifted from EDT to EST. My xmobar showed 4:30 when the local time was in fact 3:30 (and running date on the command line confirmed that my system clock was actually aware of this shift). I had to restart xmobar in order to pick up the new time zone. I repro'd the unexpected behavior by temporarily disabling my system's time syncing, setting the time to 30 seconds before the zone shift, running date to confirm I'd set the correct time, restarting xmobar, and observing. sudo systemctl stop systemd-timesyncd.service date --set="01:59:30" date I observed my xmobar clock go from 1:59 to 2:00, rather than from 1:59 to 1:00 as expected. Following the same steps, I was able to verify that this commit fixes the issue.

2020-08-07removed default arg of channel', channel (Plugins.Monitors.Volume)Keith
Both functions had a default parameter for use in some error cases. Now each accepts only one parameter (a PerChannel), and return Nothing on an error. The definition of 'channel' confused me, so I simplified it. Hopefully it's now more clear that it just applies 'toInteger' to the 'IO (Maybe CLong)' that 'channel'' returns.

2020-06-12Optimize weather plugin by reusing manager and other refactorsSibi Prabakaran
As documented in the http-client library, calling newManager is an expensive operation: ``` Creating a new Manager is a relatively expensive operation, you are advised to share a single Manager between requests instead. ``` But inspite of the haddocks in xmobar claiming that once 'Manager' is created, it will be used throughout the monitor is not true. Because for every call of `startWeather` a new manager is being created. Also I removed the option in WeatherOpts because even if it is false, it will be ultimately created in `getData` function. Also without using a manager - the plugin won't really work. So, I don't think there is any reason for this option to exist. I have introduced a new dependency http-client-tls to use the shared global manager so that we reuse the same manager every time. This simplifies a lot of code. Note that this is not really a new dependency because http-conduit already depends on it transitively.
