Changelog of @hackage/xmobar 0.39

Version 0.39 (unreleased)

New features

• New constructors for only controlling bar height: TopH and BottomH for Top and Bottom respectively
• New monitor: k10temp (Sam Kirby)
• Better handling of command line arguments for Haskell-based configuration keys (see #553 and #554)
• New monitor: Kraken (Amid Saeid)

Bug fixes

• NotmuchMail usable in text configurations (#547)
• Fix for off-by-one in padding (#560)
• Fixes for Kbd (#561)

Version 0.38 (May, 2021)

Bug fixes

• Fix off-by-one in strut calculation for Static position which reserved space for the panel than necessary and caused issues in some multi-head setups (fixes #530).
• Revert the double-UTF-8 encoding workarounds of 0.36 (#482), as they're no longer necessary with xmonad-contrib master, and aren't needed with any released version of xmonad-contrib either.
• Fix slow reactions to SIGUSR1/2 signals (reposition, change screen).

Version 0.37 (November, 2020)

New features

• New command line option --add-font (Ivan Brennan)
• New monitor MPDX that extends MPD with the ability of having a custom alias. Useful for connecting with multiple servers.
• New plugin NotmuchMail to monitor mail indexed by notmuch.

Bug fixes

• Fix date plugin not picking up DST and timezone changes (refresh timezone once a minute to preserve the optimized performace of 0.34).

Version 0.36 (August, 2020)

New features

• Monitor progress bars: a value of 0 for -W denotes an index in the -f string, similar to icon patterns but using characters.
• New tag <box> to add borders around text (Unoqwy).
• fc color background now accepts an offset (Unoqwy).

Bug fixes

• Documentation fixes (Tomáš Janoušek)
• Don't get confused by empty configuration dirs (fixes #412)
• Xft rendering: Avoid encoding to UTF8 on all scenarios. This causes issue to StdinReader monitor when the handle wasn't binary.

Version 0.35.1 (June, 2020)

• Dropped support for GHC < 8.4 (see issue #461)

Version 0.35 (June, 2020)

New features

Version 0.34 (June, 2020)

New features

• New plugin HandleReader for reading data from a Haskell Handle. This is useful if you are running xmobar from within a Haskell program.
• Build with ghc 8.10 allowed.
• Optimize date plugin by avoiding 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.
• Optimize Weather and UVMeter plugin by using global Manager instead of creating for each http request when useManager is explicitly configured as False.

Version 0.33 (February, 2020)

New features

• New template parameter <weather> for the Weather plugin, potentially displaying specific weather conditions that are occurring near the station (thanks to slotThe).
• New option --weathers, for Weather to display a default string in case the weather field is not reported (thanks to slotThe).
• New template parameter <volumestatus> for the Volume plugin, combining the effects of <volume> and <status>. This will show the volume (possibly prefixed by onString or a percentage-based string) if and only if the volume is not muted. Otherwise it will show the offString (thanks to slotThe).
• Battery and BatteryN now support FreeBSD (thanks to Dhananjay Balan).
• New option --useManager for Weather and UVMeter to decide whether to use one single manager per monitor for managing network connections or create a new one every time a connection is made.
• New more efficient time coalescing strategy for monitor updates, available with the threaded runtime: use the with_threaded flag to enable it (see #410; thanks to Tomáš Janoušek).
• Wireless supports current nl80211 API on Linux now, old Wext ioctls still available as compile-time option (thanks to Paul Fertser).

Version 0.32 (December, 2019)

New features

• New monitor BatteryN, a variant of BatteryP that lets you specify the name of the monitor in the template.
• Support for configuration file living in XDG_CONFIG_HOME (see github #99).
• Com uses safer runInteractiveProcess instead of spawning a shell (David McLean). If you're using shell expansion in your Com (e.g. "~/bin/script") here's a workaround: Run Com "/bin/bash" ["-c", "~/bin/script"] (cf. github #127).

Bug fixes

• Using the width options -w, -m and -M in battery monitors watts display (github #118).
• Using the -d option in CoreTemp (github #115)
• Fix for systems not supporting PCRE regular expressions: we use now BCEs, so regex-compat should be enough everywhere (see github #117).

Version 0.18 (June 5, 2013)

New features

• All extra argument monitors taking a string (e.g. -O for BatteryP) accept now template variables (see github #109 and #110). Thanks to Todd Lunter.

• New battery monitor extra argument, -i, for the idle status.

Bug fixes

• New TopP and BottomP alignments, taking left and right paddings (thanks to Dmitry Malikov).

• Experimental -d (start as a dock) option, may address github #67 in some window managers.

Bug fixes

• Partial (as reports go) fix for github #77.
• Safer volume plugin (Dmitry Malikov).

• Dependencies updated to latest mtl and libmpd (thanks to Sergei Trofimovich).
• Dependencies on the deprecated dbus-core removed in favour of dbus 0.10 (thanks to Jochen Keil).
• MPris2 now includes genre and composer among its fields.

Bug fixes

• DiskIO now can report overall activity in all partitions of a device which is not mounted itself (e.g., sda when sda1, sda3, etc. are the mounted partitions). Thanks to John Soros. See github #73.
• DiskU, the disk usage monitor, works again correctly on Linux, instead of randomly crashing every now and then, and reporting wrong used size.
• When using antialiased fonts, we were causing a memory leak in the X server by repeatedly allocating colors that, apparently, the server doesn't know how to get rid of (even when told so!). We're caching them now and X server memory doesn't grow.
• Compilation errors and warnings with GHC 7.6 removed (thanks to Raghavendra D Prabhu for his reports in github #71).

Known problems

Some users have reported problems with xmobar compiled with GHC 7.6 in ArchLinux: see github #78 and pointers therein. Please, send reports of any problems or successes in that regard so that we can fix any remaining issues. Thanks!
