'-' is a valid character for tags.
Commit 03e1c7d (module/network: Add link stats, 2022-04-30) introduced
two new tags for the network module: `ul-speed` and `dl-speed`. These
use the `-` character, that was previously never used in any tag.
We had two options: either change those tags to use `_` instead, or just
accept `-`s as a valid character. Going forward, I can see many people
deciding to name their tags with `-` instead of `_`, so I believe it is
better to just accept it once and for all.
Note that `-` cannot be used as the first character of a tag (e.g.
`-tag1`) since the `-` has a special meaning in `.yml` files. I don't
believe this will happen often, however, and should be easy to both
detect and correct if it does.
Not sure if Sway bug or not, but we’ve seen Sway presenting multiple
input devices with the exact same ID (and nothing else differentiating
them).
This caused a crash in the sway-xkb module, since we didn’t check if
we were already tracking the device, and thus bumped the
“num_existing_inputs” variable multiple times for the same input
object.
This lead to a content() returning an array with uninitialized
elements, and thus a crash.
Closes#229
Recent kernels, or possibly updated wireless drivers, no longer
provide the SSID in `NL80211_CMD_NEW_STATION` responses.
For yambar, this meant the SSID was always missing.
This patch fixes this, by also issuing a NL80211_CMD_GET_SCAN
command. The response to this (NL80211_CMD_SCAN_RESULTS) _may_ return
many access points. Pick out the one that we’re associated with, and
inspect its BSS_INFORMATION_ELEMENTS. This is a raw data structure
containing, among other things, the SSID.
I haven’t been able to find any documentation of the format, but could
glean enough from
https://git.kernel.org/pub/scm/linux/kernel/git/jberg/iw.git/tree/scan.c#n2313
to be able to parse out the SSID.
Note that we get a “device or resource busy” error if we try to issue
both the NL80211_CMD_GET_STATION and the NL80211_CMD_GET_SCAN commands
at the same time. Therefore, we issue the GET_SCAN command after
completing the GET_STATION command.
Closes#226
When the script module received multiple transactions in a single
batch, only the first were processed. This lead to multiple,
unprocessed transactions stacking up in the receive buffer. Every time
a new transaction was received, we popped the oldest transaction from
the buffer, but never actually getting to the last one. This is
perceived as "lag" by the user, where the bar displays outdated
information.
Closes#221
For channels that have a defined dB range, use that instead of the raw
volume range when calculating the volume percent.
Also use the same logic as alsamixer when calculating the percent from
the dB values: assume a linear scale if the dB range is “small
enough”, and otherwise normalize it against a logarithmic scale.
With this, yambar’s “percent” value matches alsamixer’s exactly.
The ‘volume’ tag remains unchanged - it always reflects the raw volume
values.
Instead, we add a new tag ‘dB’, that reflects the dB values.
Closes#202
Exports two new tags from network module, `ul-speed` and `dl-speed`.
Because these work through polling, poll-interval must be set.
Otherwise, these two tags always will be 0.
This ensures particles that are “too wide” doesn’t try to render
outside the bar, possibly overrunning both margins and borders. Or
worse, crashes yambar.
Closes#198
Seat status v3 adds a new ‘mode’ event, that informs us of the current
mode (as set by e.g. ‘riverctl enter-mode passthrough’)
The mode is exposed as a tag (named “mode”) on river’s “title”
particle:
- river:
title:
map:
default: {empty: {}}
conditions:
mode == passthrough:
string: {text: " {mode} ", deco: {background: {color: ff0000ff}}}
All FDs should now have the CLOEXEC flag set, and thus there’s no
longer needed to manually loop “all” possible FDs and (trying to)
close them.
Note: the alsa module (alsalib, actually) is “racy” - while booting
up, it temporarily opens the asoundrc file without CLOEXEC. If
e.g. the script module starts its script inside this window, it’ll
have a leaked FD. Not much we can do about it though :/
Closes#169
This patch adds an inheritable option, “font-shaping”, that controls
whether a particle that renders text should enable font-shaping or
not.
The option works similar to the ‘font’ option: one can set it at the
top-level, and it gets inherited down through all modules and to their
particles.
Or, you can set it on a module and it gets inherited to all its
particles, but not to other modules’ particles.
Finally, you can set it on individual particles, in which case it only
applies to them (or “child” particles).
When font-shaping is enabled (the default), the string particle shapes
full text runs using the fcft_rasterize_text_run_utf32() API. In fcft,
this results in HarfBuzz being used to shape the string.
When disabled, the string particle instead uses the simpler
fcft_rasterize_char_utf32() API, which rasterizes individual
characters.
This gives user greater control over the font rendering. One example
is bitmap fonts, which HarfBuzz often doesn’t get right.
Closes#159
On i3, users are currently greeted with:
err: modules/i3.c:94: workspace reply/event without 'name' and/or
'output', and/or 'focus' properties
This patch makes ‘focus’ an optional attribute. When missing, we
assume a node-count of 0, which means the workspace’s ‘empty’ tag will
always be true. Document this in the i3 man page.
This is a boolean option. When set, “N:” prefixes will be stripped
from the workspaces’ name tag, *after* having been sorted (if the
‘sort’ option is being used).
This makes it useful to arrange the workspaces in a fixed order, by
prefixing the names with a number in the Sway config:
set $ws1 “1:xyz”
set $ws2 “2:abc”
Then, in the yambar config:
i3:
sort: ascending
strip-workspace-numbers: true
Fonts in the configuration may now be a comma separated list of
fonts (all using the fontconfig format). The first font is the primary
font, and the rest are fallback fonts that will be searched, in order.
