Re: [9fans] GSOC: Drawterm for the iPhone
Killed. From the license agreement for iPhone developers (which requires a free Apple Developer Connection account to view; sorry): 3.3.3 Without Apple’s prior written approval, an Application may not provide, unlock or enable a enable additional features or functionality through distribution mechanisms other than the App Store. drawterm may be used to gain access to a large repository of optional software (/n/sources/contrib, /n/sources/extra). An ill-informed lawyer may bring this up: 3.3.2 An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise. No interpreted code may be downloaded and used in an Application except for code that is interpreted and run by Apple's Published APIs and built-in interpreter(s). This is a shaky one. While drawterm does not itself run code, it allows you to connect to a computer that runs its own programs. But even if we did overcome all this... We have scribble, and rio is optional, so I don't think input is too much of a problem. A pain, yes, but not a problem. How about determining button 1, 2, 3? Triple-touch? You might get tired too easily.
Re: [9fans] GSOC: Drawterm for the iPhone
Also, we obviously cannot use rio, unless we greatly restrict the user's visibility. Unless we provide zooming?

Re: [9fans] Small program PlanKey (paraphrase of DOSKey)
This code is interesting. I do see one problem: commands that take up
more than one line won't be stored in the history properly, so each
line will get its own entry. But this is a nice use of pipes!

Hi all,
In Plan9 I missed the simple way to repeat previous (or previous of
previous etc.) command in the terminal.
I prepared a very small (an stupid) program to allow that.
Compile the following source code and run it in that way:
8.out | rc -i
You can insert the commands, and if you want to walk through the
history, just press CTRL+K (backward) or CTRL+L (foreward).
That is all, folks. ;-)

What is troff? troff is a document preparation system, much like TeX or Microsoft Word. troff is one of the first of these systems to support fonts in italic and drawing on the page. It was developed by the late Joe Ossanna and is the latest and newest in a long line of document programs. troff is most like TeX in that the document is a text file containing words with formatting commands mixed in. This means you'll have to get used to the command line. Three primary versions of troff are used today. The official version, based of Ossanna's work, is in the Plan 9 from Bell Labs operating system. The most common one is groff, a version made for the GNU project. There is also Heirloom troff, based off the ones by OpenSolaris. All three are free software. So as you can see, troff is a Unix tool. But if you are on Windows, don't despair: there are ports of these tools to Windows. I will be running Plan 9 for my demo. Let's start by creating a simple document. Create a new text file: first_troff and edit it: acme first_troff Now let's type a few words: hello, world Save your work. In my case, I middle-click the Put at the top. Now comes the fun part. In Plan 9, to preview the document, you say troff first_troff | proof or troff first_troff | page I will use page. With GNU, you convert to a PostScript file and open it with an image viewer: troff first_troff | grops first_troff.ps (Heirloom goes here.)

When you're running a server, such as ext2srv or dossrv. If I recall correctly, this was discussed before. 2) Reading pwd.c I can see 'char pathname[512]' at the beginning of the main function.

No. How many characters can be stored in an absolute pathname is program-dependent. 3) Why do I have to press END key several times to get to the bottom of a window (usu when there is a lot of output text from the issued command)? (The rio maunual says just one press.) rio windows don't scroll by default. To enable scrolling for a certain window, middle-click and hit scroll, or type echo scroll /dev/wctl To make scrolling the default, edit $home/lib/profile and change every instance of exec rio to exec rio -s Log out and log back in. 4) What is the sense of bind 'sth' 'the_same_sth' ? (like 'bind / /' or 'bind /usr/ruda/a /usr/ruda/a') Think of it as making an alias or link. 5) When I do cd mkdir a mntgen a bind lib a/b unmount a all these command finish ok, but I am left with bind /usr/ruda/lib /usr/ruda/a/b in the namespace (see the result of the 'ns' command; there you can also spot that after issueing the 'mntgen' command a line 'bind /usr/ruda/a /usr/ruda/a/' appears; that relates to my 4th question; this bind is the one removed by the 'unmount' command).

No. Well... that's an answer, but not very constructive indeed. When do those files dissapear? R. When the namespace disappears. You can ignore the file even being there. There is a difference between the file and how the program uses them. If the program (rc) doesn't have a function given a name but /env does, it makes no difference. rc will overwrite the file when you redefine the function.

After that I decided to move my changes to /rc/bin/termrc.local and restore termrc .

(I solved it with yesterday command but I would like to know why I was not successful with pull command) Antonin Sorry, but I got screwed by that too. -s only works if there is a conflict. You'll have to manually copy it from /n/sources/plan9/. Type 9fs sources cp /n/sources/plan9/rc/bin/termc /rc/bin/termrc
