Re: [9fans] What are you using Plan 9 for?
i'm using plan9port (thanks, rsc) on linux for some 8 years now, for all coding - mostly low-brow web dev primarily Acme as IDE, Rc and awk for scripting the necessary tooling back when i was stuck at a corpo and had to use Windows on workstation, i installed p9p on one of build servers and ran Acme over LAN, through Xming there was no noticeable latency; it felt snappier than the corpo blessed IDE on windows my typical setup is: slackware linux, p9p, Acme maximized on the right screen. a few years ago i've coded a minimalist IRC client for Acme, was surprisingly comfy, but never followed it up another small use case was simplistic HTTP server for game map files coded in Rc; just enough to handle HTTP GET with Range header. was maybe 50 lines of shell.

[9fans] Acme - built in command; external command
is it possible to execute built-in command and external command with one mouse click in Acme? something like: Putall; mk
Re: [9fans] simple rc problem in p9p (on OpenBSD)
use a list. lists are created either by the parentheses:
% w = ( A B C )
% # note no space before the backslash
% wMultiline = (\
X\
Y\
Z\
)
% echo $w $wMultiline
A B C X Y Z
% for(i in $w) {echo $i; echo XXX}
A
XXX
B
XXX
C
XXX
or by globbing:
% text_files = *.txt
or by expanding a whitespaced text:
% text_files = `{ 9 ls *.txt }
note the p9p's "ls" quotes whitespace in file names properly for Rc
lists are single-level; merging two lists produces new one of single
level, with all the elements in order
% a = ( foo bar )
% b = ( aa $a bb )
% echo $a
foo bar
% echo $b
aa foo bar bb
side note, the ^ operator has interesting uses for lists:
% a = ( foo bar baz)
% b = ( aa bb cc )
% flat = ( first $a last )
% echo $a
foo bar baz
% echo $flat
first foo bar baz last
% car = $a ^ $b
% echo prefix ^ $a
prefixfoo prefixbar prefixbaz
% echo $car
fooaa barbb bazcc
[9fans] Acme: moving the cursor to tag line
i've realized i never use the Esc key in Acme. meanwhile, i often go through cycle of: - type chunk of code - grab mouse, focus tag line - type a command - grab mouse, execute the command would it make more sense to have Esc function as the "position cursor & focus at the end of tag line of the current window" shortcut? bit of a vi-like behavior; semi mode-switch, from input to execution *area*. have anything like that been tried in Acme? -- dx

[9fans] Rc redirect woes
bug in plan9port rc(1):
straightforward mix of input and output redirects inside of a block (`for'
loop, `if' clase) causes subsequent commands' stdout to be errorously
redirected too.
the trigger is one or more input redirects (<{COMMAND}).
problem disappears once executions falls outside of the block.
#!/usr/bin/env rc
if (true) {
echo bah blah blah > /dev/null
echo AAA works just fine
cat <{echo aaa} > /tmp/junk-if.txt
echo this gets redirected errorously
echo this gets redirected errorously
}

Re: [9fans] Acme 2-1 chord arguments
dirty 1.) rc -c 'git '^
note the space after git
idiomatic 1.) use win(1), pass 'command' argument a script which executes
git for each line of input as arguments through rc(1) to evaluate the
arguments in the usual way
2.) you can pass complex regular expression as argument to grep(1), without
rc(1) choking on metacharacters.
the argument is guaranteed not to have unforeseen side effects.
example win(1) script:
#!/usr/bin/env rc
orig_ifs = $ifs
PAGER=cat
while (true) {
ifs=''
echo -n 'git> '
line = `{read}
ifs = $orig_ifs
rc -c 'git '^ $line

[9fans] split(1): -e vs. -n, -f
hi list, both behavior and code indicate that split(1)'s `-e' (split by regular expression) doesn't play along with either `-n' (line count) or `-f' (output file prefix). the former is somewhat understandable, but the later is strange in lieu of `-s' (output file suffix) working just fine. that by accident or is there some rationale? -- dexen deVries [[[↓][→]]]

[9fans] marking lines in Acme

[9fans] p9p mk rc help
Hi list,
apologies for the keyword overload ;-)
I have a plan9port mkfile using Rc (MKSHELL=$PLAN9/bin/rc), a recipe
contains pipeline: FOO_COMMAND | BAR_COMMAND.
What is the correct way of detecting failure exit status of
FOO_COMMAND (a networked operation) and ignoring exit status of
BAR_COMMAND?
the best i came up with is very ugly:
target: prereq
FOO_COMMAND | BAR_COMMAND
st = $status
if (~ $st ?* ^ '|' ^ *) {
echo FOO_COMMAND failed
exit 3 }
seems the | in pattern has to be quoted, otherwise is interpreted as
pipe operator.

your selection lacks the final LF to make Rc happy ;-)
a quick and dirty hack would be to always append LF:
exec /usr/local/plan9/bin/rc <{9p read acme/$id/rdsel;echo;}
tested with:
echo foo bar
rc <{9p read acme/$winid/rdsel; echo; }
selecting bare `echo foo bar' (without LF) gives syntax error; selecting whole

How do I get to process x.c as x.c and not X.C. there's no difference between FAT12/16 and FAT32 in treatment of file names, it is entirely up to FS driver to create or skip creation of LFN (Long File Name) entry, and to use or skip reading an LFN. every file on FAT has 8.3 name, and may, but does not have to have, an LFN. the 8.3 name is of limited charset (one of DOS or WINDOWS codepages) and upcase only, at least in canonical format. to store lowercase characters, you need LFN. IIRC, some version(s?) of fat drivers on linux did not create LFN for a file when the long filename was matching case INsensitive the 8.3 file name, essentially leading to loss of character case information. perhaps something alike is at play here. -- dexen deVries [[[↓][→]]] ``we, the humanity'' is the greatest experiment we, the humanity, ever undertook.

thanks Erik, it makes sense to me now :-)
i'd rather have if's $status visible only to the first statement following it,
for example:
if (foo | bar | baz) { # sets $status
if (! ~ $status ) { # uses $status
handle_particular_kind_of_pipeline_failure
}
do_other_stuff # should not be affected
}
do_yet_other_stuff # should not be affected either
...but guess rc's semantics are almost set in stone by now :-)

[9fans] p9p rc flag e +
in p9p rc, an `if (/bin/false)' statement without `if not' statement causes non-empty $status, and thus will terminate mk. for example, the attached mkfile returns error for target `breaks', but works for target `works', with the difference being that of trailing `if not'. from my point of view, the `if (/bin/false)' statement spills the non-empty $status from the conditional expression to its outern scope. perhaps this is to simplify implementation of `if not', but it irks me. is that really the expected behavior, or is it a quirk of p9p rc? is there a point to, or an use case for this behavior? -- dexen deVries [[[↓][→]]] MKSHELL=$PLAN9/bin/rc test:VQ: positive negative echo success. positive:VQ: if (test -e mkfile) echo the file exists negative:VQ: # any file or dir that is sure not to exist # if we have a file `mkfile', then for sure we don't have a dir `mkfile/' if (test -e mkfile/) echo SHOULD NOT BE REACHED

you are right. i use Edit ,d to preserve general window layout.
i'm not happy with Acme's placement of +Errors window in my default workflow.
in two columns, i keep one directory (project root) window, one +Errors window
beneath it (syntax errors, upload progress †, scratchpad) and some 1...6
source code file windows spread 'round.
btw., the patch may not apply cleanly since my p9p fork has `Look' disabled

[9fans] Acme: indicator of running process
hi list, a long running process (e.g. `git submodule update') does not give any indication as to whether it is running or dead already, save for some progress messages, if any. i would like a clear indicator in Acme's $cwd+Error window the process outputs to. i guess the state of the /dev/stdout of Acme's child process whould be a good indicator for most cases. is there any handy hack to indicate whether the /dev/stdout is open in any particular Acme window? or any other indicator whether a process is still working or dead? yes, i know names of processes are displayed in top Tag line, but in my cases, usually several gits are ran along (git gui, git submodule, etc.etc.) using p9p Acme. cheers, -- dexen deVries [[[↓][→]]]

another quick hack:
#define exit(status) do { exit(status); return 0; } while (0)
with do{}while() guarding against treating it as an expression.
