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`

2021-05-14Fix delayed reaction to USR1/2 signalsTomas Janousek
While using xmobar to reproduce/fix a bug in xmonad I noticed that xmobar doesn't react immediately to the signals to reposition or change screen. Apparently none of the Xlib functions called from `repositionWin` flush the Xlib output buffer (XMoveResizeWindow is known to not flush, although it's unfortunately not documented), so when compiled with the threaded runtime that runs XNextEvent in a separate thread, the reposition is sent to the X server only later when other stuff happens. With all monitors set to refresh once a minute, this can take a looong time. (It's entirely possible this happens even without the threaded runtime, I didn't test that, sorry.) The fix is to call XSync at the end of `repositionWin`. While at it, I spotted that drawInWin calls XSync with discard=true, which seems like a mistake. We don't want to discard any events, do we? (In practice, I'd expect the `eventer` thread to read all events even before the drawing thread manages to discard them, so even if this discarding XSync ever had any reason to be there, I don't think it does anything meaningful these days. I may be wrong, though.)

2021-04-27Revert "Conditional encoding …" and "Avoid double utf8 encoding" (#482)Tomas Janousek
This reverts commits c6669e26e1 (partially; changelog entry kept), 73e02934d6, 78efa5900a. These commits were introduced as a workaround for a double UTF-8 encoding bug in xmonad-contrib which itself was meant to be a fix/workaround for another issue. We have now identified the underlying issue and fixed it right at the root, so this entire cascade of hacky (and wrong) workarounds can be safely reverted. Thankfully, none of the xmonad-contrib hacks made it into a release, so there's no backward compat to worry about. Should anyone be interested in the details, https://github.com/xmonad/xmonad-contrib/commit/63e31ccd8d2865863778207b679f806941bf2788 provides a summary and links to all the related issues and PRs.

hlint started failing recently: src/Xmobar/X11/Text.hs:121:32: Error: Parse error: on input `-' Found: textExtents (Utf8 fs) s = do let (_,rl) = wcTextExtents fs s > ascent = fromIntegral $ - (rect_y rl) descent = fromIntegral $ rect_height rl + fromIntegral (rect_y rl) return (ascent, descent) It's probably a change in the parser or something, didn't really look into it, just changed it to something that's parsable.
2021-04-26Fix off-by-one in strut calculation for Static positionTomas Janousek
Pixel intervals in _NET_WM_STRUT_PARTIAL are closed, not open [1], so xmobar of width 1920 at x=0 needs to be encoded as ⟨0, 1919⟩, not ⟨0, 1920). The code already does this for Top/Bottom positioning, but Static has been buggy for years.

2020-11-19test: Fix flaky CpuSpecTomas Janousek
Failed at least once in GitHub Actions: predicate failed on: "Cpu: <fc=red>100</fc>% <fc=red>##########</fc>" Also, there's no need to guard the Xmobar.Plugins.Monitors.CpuSpec module with the with_alsa flag. (And it doesn't really work anyway, hspec-discover doesn't care about what modules are declared in cabal, so stack/ghc complains that "These modules are needed for compilation but not listed in your .cabal file's other-modules: Xmobar.Plugins.Monitors.AlsaSpec" and then fails to detect changes in those modules.)
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.

2020-11-15Fix crash on <fn=1>x</fn> when no additional fonts are specifiedTomas Janousek
This fixes the following crash that happens with the default xmobar configuration (using HOME=/ makes xmobar ignore ~/.xmobarrc): $ echo "<fn=1>x</fn>" | HOME=/ xmobar xmobar: Prelude.!!: index too large Commit 3e9e1cb9d300 ("Fix crashes/busy looping happening via index") meant to fix this but apparently it only fixed indexing of fontlist, not voffs, so the crash was still there. Fixes: https://github.com/jaor/xmobar/issues/504
2020-11-15Fix vertical centering of additional fontsTomas Janousek
The readme says additional fonts are centered vertically if a corresponding offset isn't specified in `textOffsets`, but this didn't happen as we used the first font's metrics for centering of all fonts instead. Fixes: a2365debfaba ("New configuration parameter `textOffsets` (fixes #311)")
