2014-09-16Locks: Implement event-driven locks indicatorAnton Vorontsov
This commit does more fundamental rework of the "Locks" plug-in: now the plug-in is fully event-driven and thus extremely power-efficient, effectively zero CPU consumption while idling.
2014-09-16Locks: Rework to avoid unnecessary display reopeningAnton Vorontsov
The extremely useful "Locks" plugin eats quite a lot of CPU (>2% here on a old-ish laptop), unfortunately. The plug-in unnecessary reopens the display, which is quite expensive operation. It results into 16 syscalls: socket(PF_LOCAL) -> connect(sun_path=@"/tmp/.X11-unix/X0"}) -> getpeername() -> uname() -> access(".Xauthority") -> open(".Xauthority") -> fstat() -> mmap() -> read() -> close() -> munmap() -> getsockname() -> fcntl(F_SETFD) -> fcntl(F_SETFL) -> shutdown() -> close() This is almost half of all the syscalls that we ought to execute for the plug-in to work. Now, considering the useful work and that "Locks" runs every 200 milliseconds, it gives us >300 syscalls (and a lot more wake-ups) per second. This commit fixes the reopening issue, effectively halving the CPU consumption (down to ~1%). The patch also makes it easier to implement event-driven indicators that will reduce the idle CPU consumption to 0.
2014-09-14Implement DynamicString for Monitors supporting vbar.Alexander Shabalin
* Batt * Bright * Cpu * Disk * MPD * Mem * MultiCpu * Net * Volume * Wireless
2014-09-14Add DynamicString as an alternative to vbars.Alexander Shabalin
* DynamicString is an Int -> String which takes a value from 0..8 and produces a string with this value embedded. Usefull for replacing vbars with icons: an icon per one of 9 states. * API is similar to that of vbar. * Default parser of DynamicString produces a function of `i` to a string that replaces all occurences of "%%" with `show i`

2014-08-09New Plugin MarqueePipeReaderReto Hablützel
Display a long text from a pipe with marquee. It wraps around with a given separator and the length may be specified as well as the delay in 10th seconds. See readme for an example.

Adaptive units are computed only if suffix is enabled Otherwise we fall back to the old computation (KB)
2014-06-27Fix for CPU monitor on long-running systemsRobert J. Macomber
After running long enough, the numbers in /proc/stat get big enough that they will not fit in a Float without loss of precision, which leads to erratic results such as reporting "NaN%" CPU usage. This commit simply keeps the numbers integral until producing the final percentage result.
2014-06-09Allow user to define punctuation.Conner McDaniel
I'd like to be able to choose which punctuation to use. All my other xmobar plugins use a colon and a space (e.g. `B: 100%` for battery), but this one leaves the space out (e.g. `E:1`) which is mildly annoying. It would be nice to let the user choose if he/she would like to use something other than a colon or to add extra whitespace.

2014-03-09Handle inexistent devicesReto Hablützel
If a device is unplugged without prior unmounting, it still appears in the /etc/mtab file, which is used for this monitor. The problem is that this monitor canonicalized every path regardless of whether it actually existed or not. I basically added the 'only canonicalize if file exists'.

2014-02-25have disabled plugins still accept inputAdam Vogt
This change lets xmobar compiled without -fwith_inotify accept a config that mentions the Mail plugin with a warning (and display an Updating...).
2014-02-15Fix runaway memory leak when expanding invalid tags, and remove errornand
Don't recursively parse on the case of an error. Also, in the case of an error, instead of replacing by an error message, replace by the tag itself to prevent mangling strings that legitimately include < and > characters, for example song titles when using the MPD plugin. I'm not sure how to handle this better. Honestly, I would like to remove the recursive parsing altogether but this works for now. Consider filing an issue for a proper resolution of this. I don't want rogue tags expanding themselves in my song titles.

2014-02-05Drop curl dependency for the HTTP moduleBen Boeckel
2014-02-05Find out whether the weather monitor is likely to blockBen Boeckel
Uses the HTTP module to do the work rather than curl.
2014-02-05Add a "ready" check to MPD monitorsBen Boeckel
If the MPD server isn't responsive or the network is down, MPD will no longer block xmobar from doing its job.
2014-02-05Add support for monitors to indicate they may blockBen Boeckel
Useful when the network is down or something else is causing issues.
2014-02-04Use MemAvailable from meminfo if possibleBen Boeckel
Use the functionality from newer kernels if available. Basically, the free+buffer+cache metric is a massive hack and not accurate anyways (e.g., not all cache can be swapped out and kernel accounting can change whenever). Kernels 3.14 and newer have MemAvailable in meminfo which is more accurate; use it if possible.
