My bad (as expected); it apparently arose because of starting rio on a
small screen and then switching to a larger one. I hvae now set this
up properly, and the problem has disappeared.

I forgot the EOF tokens, sorry for the noise. I shouldn't do this while tired,

Re: [9fans] Whats the default font in Acme?

[Ethan Gardener]

Years ago, I used to convert fonts by copying from fontsrv -p. This was due to 
bugs fontsrv had at the time, but I guess it may still be useful. 

Here's the 4 scripts I used to use, for whatever they might be worth.

% for(n in _get*){echo 'cat >' $n '< _get_1_size < $dir^font
if(! ~ $status '') exit
fontsrv -p $name^$dir^font | 
ssam '1d
,x=.* =d
,s=.+=& > '^$dir^'&=g
,x=^=i=fontsrv -p '''^$name^$dir^'''=' | rc

cat > _get_all_sizes <[1=2]
mkdir -p $dir
fontsrv -p $name^$dir^font > $dir^font
fontsrv -p $name^$dir^font | 
ssam '1d
,x=.* =d
,s=.+=& > '^$dir^'&=g
,x=^=i=fontsrv -p '''^$name^$dir^'''=' | rc
}

cat > _get_all_sizes-noaa <[1=2]
mkdir -p $dir
fontsrv -p $name^$dir^font > $dir^font
fontsrv -p $name^$dir^font | 
ssam '1d
,x=.* =d
,s=.+=& > '^$dir^'&=g
,x=^=i=fontsrv -p '''^$name^$dir^'''=' | rc
}
}

cat > _get_all_sizes-prefix-version < $prefix^.font

fontsrv -p $name^$dir^font | 
ssam '1d
,x=.* =d
,s=.*=& > '^$prefix^'-&=g

That is how I used to do it, as in the man page; but for some,
probably local, reason the problem I described now arises
(actually as of commit 5f0fa18, fontsrv: handle non-BMP runes on X11).
I will look into that, and use the mountpoint in my home dir in the meantime.

Re: [9fans] Whats the default font in Acme?

[Russ Cox]

For what it's worth, you don't need to mount fontsrv anywhere.
You can just use 'fontsrv -p .' to list the fonts,
and then refer to them as /mnt/font/Name/SIZEa/font.
For example:

/usr/local/plan9/bin/acme \
    -f /mnt/font/LucidaGrande/12a/font \
    -F /mnt/font/SourceCodePro-Regular/12a/font

In that form, acme will "open" /mnt/font/... by reading fontsrv -p's
output.

Best,
Russ

It seems to have been some kind of permissions problem. If I run
fontsrv with a mountpoint created in my home directory,
it works perfectly.

Even running acme on a FreeBSD host & displaying it on a MBP screen
there was no perceptible delay. May be you have a slow disk? You can
do "strace -r fontsrv" to see where time is being spent.

It works fine on my Arch, too. On the FreeBSD system, do you find
fontsrv introduces the lags I described?

I just tried fontsrv on FreeBSD system and it certainly finds .ttf
format fonts installed on the system.

If you don't have access to any other  truetype fonts, you might want to
try Go font to check. Here's the info:

Works fine on my macbook pro.

$ 9p ls font | wc
 822 822   15179

Note this from the fontsrv man page:

Fontsrv has no support for X11 fonts; on X11 systems, it
will serve an empty top-level directory.

On my system (Arch 5.10.16) using fontsrv introduces 2-3 second delays
whenever a program needs to know about the font,
e.g. when opening acme the window first turns all black and then all
white before the columns appear; similarly, lc always takes about
2 seconds before the listing appears.

On my system (Arch 5.10.16) using fontsrv introduces 2-3 second delays
whenever a program needs to know about the font,
e.g. when opening acme the window first turns all black and then all
white before the columns appear; similarly, lc always takes about
2 seconds before the listing appears.

I just ran “echo $font” from inside Acme and it says

Lucida Sans.

It's almost always specified with font= so you can `echo $font` to see what it 
is. (If font isn't set, I think there might be a builtin default of `fixed`.)

As for the actual font, non-9front systems likely have Pelm or Lucida Sans 
[Mono] for their default font. Lucida is an old bitmap font, not the newer 
scalable Lucidux Sans. I don't see any sign of Pelm outside Plan 9 circles and 
I'm sure it's also a bitmap font by design. *However,* a quick web search for 
`"pelm" font` turned up a Hacker News page with opinions that Lucida Grande is 
very similar to Lucida, and "Go Mono is closer to (or a remake of) the Pelm 
font from Plan 9." Both of these are scalable.

The article it's commenting on announces the Go fonts, containing sample images:
https://blog.golang.org/go-fonts

HN subthread with cited/quoted opinions:
https://news.ycombinator.com/item?id=12973952
HN thread:
https://news.ycombinator.com/item?id=12973716

Personally, I'd like to see a scalable version of the old GEM font, although I 
liked it more for its style than its readability when I was a teenager. ;)

sam-d has done this.  A hidpi version of the VGA font ready for Plan 9
can be downloaded from http://sciops.net/downloads/vga/hugevga.tgz

Once unpacked under /lib/font/bit/, you can set
font=/lib/font/bit/hugevga/unicode.font to use it.

You can use bdf2subf [1] with my hidpi vga font [2] to get this.  Maybe
someone already has?  If so, I'd be happy to add it to the VGA pile.

And is there a version for high dpi displays?


What acme version?

There's 9legacy, 9front, plan9ports, inferno and acme-sac, at least. 
Depending on the system this might be different.


On 9front (and maybe on 9legacy?) It's the font you specify with font=, 
which is vga by default.
