games/dmid uses the same sample rate as the chip for music, but other
applications do not. opl3 and its older version opl2 (not in 9front)
read an input stream of commands in basically IMF format, something
used in other id Software games and some others, which assumes a
given input sampling rate: 700 Hz for Wolfenstein 3D music, 560 Hz
for Commander Keen, 60 Hz for Ultima 6, etc.
The opl3 emulation on the other hand is not really intended to run at
a sampling rate different that the chip's 49.716 kHz sampling rate.
Previously, we assumed it runs at 44.1 kHz and just used the input
rate as a divisor to get the number of samples per delay tic.
From what I understand, the correct way to use it for accurate
emulation is to run the opl chip emulator at its intended sampling
frequency, then downsample to 44.1 kHz. This means better output
but more code. The alternative is to basically do the same as
before rev 8433, except with no buffering, but at accuracy/quality
loss. This change implements the former and just forks pcmconv to
deal with resampling.
this fixes real-time applications.
-n previously specified a rate divisor rather than the rate itself,
which was used for specific applications outside of 9front. instead,
just set the rate directly, more useful and straightforward.
This patch adds dirmodefmt from fcall.h to pretty-print file
permissions, similarly to ls -l. I didn't notice any performance
degradation.
I hope no-one relied on the old behaviour.
i have found one bug. when i put glenda in a position like this
i somehow win, but the glenda can escape from there.
in addition, i have changed the games manpage to include more info about glendy.
The old parser code was rubbish and only worked for trivial
expressions. The new code properly handles complex expressions,
including short circuit evaluation.
As such, the BUGS section has been removed from the test(1) man page.
The description of an unimplemented feature has also been removed.
Passwd used to produce a very confusing error
about DES not being enabled whenever the password
was mistyped. This happened because we attempted
to guess what authentication method to use, and
preseneted the error from the wrong one on failure.
This puts the legacy mode behind a flag, so that
we don't even try the old method unless it's
explicitly requested.
hget supports adding custom headers with -r;
it makes sense for hpost to do the same, both
because custom headers are more likely necessary
with POSTs, and for consistency.
The -v flag now does not create a new rio window,
while -w flag does (restores the old behaviour).
This allows vmx to run under vncs and is in general
mode aligned to other emulators and programs.
Upas/marshal -F was broken with the '-8' command, and silly
without it: It used aliases passed on the command line, so
the destination address was ignored with -8 was passed.
In addition, it would create a new mailbox for any aliases
being sent to, instead of putting them all in one location.
The new -S option is similar to -F, but specifies where the
message should go.
The format produced by `diff -u` is inferior to that
produced by `diff -c`, but it's what ape/patch and
unix patch expect, so it's useful to generate it.
This patch adds `diff -u`.
Following is a list of functional changes:
* The -o flag outputs the entire buffer to the length returned
by the syscall, or, in case of fd2path(2) and errstr(2), to '\0'.
* The -x flag is removed; the above makes it possible to pipe
into xd(1) to get the same result.
* The -s flag uses dirfmt(2) to format the stat message, instead
of trying to imitate ls(1).
* Stderr reports are normalized and made easier to parse.
The code also suffered a number of stylistic changes.
Fix inconsistencies between programs and their usage
messages, correct instances where information seems
to be missing or lost. This includes missing arguments,
making usage consistent with manuals, and so on.
this is a reimplementation of infernos os(1) command, which
allows running commands in the underhying host operating
system when inferno runs in hosted mode (emu). but unlike
inferno, we want to use it to run commands on the client
side of a inferno or drawterm session from the plan9 cpu
server, so it defaults to /mnt/term/cmd for the mountpoint.
C99 comments have been the default in compilers for something like 20 years
now. This means we don't need to remember to turn it on when porting software,
and gets rid of cryptic errors about unterminated character constants when
someone writes something like:
// Didn't need to...
We still accept the flag to avoid breaking mkfiles, but we do nothing with it.
This also removes the documentation, since the option does nothing now.
"I sometimes find myself on either slow or data-capped network links where downloading images isn't ideal. Attached is a simple patch to mothra that changes the 'k' command to not only remove already-downloaded images from a page, but also toggle a state such that mothra won't attempt to download images on future visited sites until 'k' is toggled again. This also adds a '-k' flag to mothra which enables the flag at startup." --Jeremy O'Brien<neutral@fastmail.com> on 9fans
- fix overwriting channel 10 with channel 9
- fix using channel volume instead of last volume when setting note
(fixes d_doom and others)
- remove useless state
