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.
2020-06-05Optimize date pluginSibi Prabakaran
We avoid calling getTimeZone for each of the time the date has to be updated. Instead, it's computed once at the start and re-used for each invocation. Looking at the implementation of 'getTimeZone', we can see that it's very expensive: https://www.stackage.org/haddock/lts-15.15/time-1.9.3/src/Data-Time-LocalTime-Internal-TimeZone.html#getTimeZone It calls a C FFI each time to get the time zone (getTimeZoneCTime). This is something which we can avoid and the MR implements that. I have been using my xmobar with this patch and the result has been quite good. My xmobar CPU usage has used to hit 3~7% intermittently. With this MR, It hits only 0.7% intermittently which is nice. :-)

2020-05-02Avoid busy looping by not catching all exceptionsSibi Prabakaran
This specifically avoids situation described in this issue https://github.com/jaor/xmobar/issues/438 where the handle was throwing the IOException continously in a loop: <stdin>: hGetLine: invalid argument (invalid byte sequence) It happened because my system's environment was right, but the proper behaviour hear would be to let it to throw the exception rather than leading to a busy loop. I did some git blame to find out that this commit introduced the behaviour: https://github.com/jaor/xmobar/commit/fc24dc1874dcf7c9e66e21502a58b40cbe627c85 but there was no reason mentioned in the commit for trying to capture all exceptions.

hGetLineSafe is always hGetLine and hence we can directly use it.

2020-04-12Add a HandleReader PluginPavan Rikhi
This adds a new `HandleReader` plugin, which displays data from a Haskell `Handle`. This is really only useful if you are running xmobar from within another Haskell program, but lets you avoid the mechanics of creating a named pipe with the proper file permissions. Instead, you can use `System.Process.createPipe` to make a pair of read & write Handles. If you pass the read handle to HandleReader, you can use hPutStr on the write Handle to send data to xmobar from your application code.

2020-03-05Wireless: fix hlint warnings, reenable CI checksPaul Fertser
This makes the code hlint-clean for --cpp-define=USE_NL80211, --cpp-define=IWLIB and without --cpp-define too.

2020-02-25Wireless: support NL80211 userspace <-> kernelspace APIPaul Fertser
NL80211 was introduced in Linux 2.6.24 in 2007 as a new extensible universal API, replacing "wireless extensions" ioctls. It works on top of netlink, and allows direct communication to cfg80211 kernel subsystem. Since then it became a hard requirement for all upstream wireless drivers to hook into cfg80211 (SoftMAC drivers do it via the common mac80211 layer). There's still additional compatibility code that allows limited Wext functionality for cfg80211 drivers but it's buggy and can be disabled altogether when CONFIG_CFG80211_WEXT is not set. This patch makes use of "netlink" Haskell library which doesn't have any additional runtime dependencies (so neither iwlib nor libnl are required). The operation is the same as performed by "iw dev <devname> link" command. The signal level is transformed to "quality" by first clamping it to [-110; -40], then adding 110 and dividing by 70 (same meaningless formula as used by the cfg80211 Wext compatibility layer). "essid" template argument is replaced by more appropriate "ssid" (with the old variant still available for backwards compatibility)
2020-02-22Refactor code from tenthSeconds to doEveryTenthSecondsTomas Janousek
A preparation for timer coalescing: tenthSeconds is just a sleep whereas doEveryTenthSeconds enables using a central timer and waiting for all monitors to update before refreshing the window. This commit is just a simple refactor, the actual timer coalescing code comes later.
2020-02-11Battery: fix time calculations on some Linux systemsPaul Fertser
The calculations are based on the assumption that current_now (or power_now) are always positive. However, power_supply documentation in the kernel sources say nothing about it, and so some drivers provide a signed value (e.g. bq27xxx_battery_current). Discovered and fixed on ac100/paz00 netbook.
