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.

With this change, xmobar should respect the data which it gets. Xmobar should just render the data instead of trying to encode it.

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.

2020-08-07Allow font bg to be taller (or smaller)Unoqwy
Implemented only for XFT fonts. Adds a new "part" in the fc tag. > Example: <fc=white,gray:0>foo bar</fc> will make the font background as tall as the bar (absolute offset, here set to 0 for both top & bottom) Changes ColorString to ColorInfo, containing both top and bottom offsets. The "colors string" is still in only one string.

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. :-)

2020-05-10Fix crashes/busy looping happening via indexSibi Prabakaran
Right now, with the `StdinReader` plugin enabled - you can crash/cause busy looping of xmobar if the following html file is opened: ``` <html> <head> <title>hello <fn=1>string</fn> </title> </head> </html> ``` More details about this bug is here: https://github.com/jaor/xmobar/issues/442#issuecomment-625706001 This MR also fixes another bug which produces a crash in xmobar if you pass non integer items between fn: <fn=crash>

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.
