Marc, stty is not the same as tty; tty is a device, but stty is a tool to query or change a tty's settings. On 2023-07-28 06:35:18 Marc Remes wrote: > Hi Leslie, > > A redirected pipe is not a tty.

Hi Leslie, A redirected pipe is not a tty. That's why the output is empty. try pipe 'command tty | console' There are methods to connect a pseudo tty, but I don't think we need to adapt njpipes to support that. ref: https://gamlor.info/posts-output/2021-05-29-tty-in-java/en/ Marc |

Hi, Can someone with a Linux machine please take a look at this? I want to replace the bash script I'm using to extract terminal dimensions with a nrx pipeline (see attached bash scripts), but I get no output from the command stage when I execute stty. The nrx pipeline is much simpler than the bash one, but there's something strange about stty. Perhaps it writes directly to the terminal instead of to stdout? If so, (how) could the command stage capture it? Do we need a <tty stage instead? Anyway, here are the nrx pipelines: | $ pipe 'command stty --all|take first 1|specs word 5 next|strip trailing string /;/|console' # should return #rows | rc=0 | $ pipe 'command stty --all|take first 1|specs word 7 next|strip trailing string /;/|console' # should return #columns | rc=0 In fact, just | $ pipe 'command stty --all|console' | rc=0 produces no output at all, while running stty --all directly in the terminal produces | $ stty --all | speed 38400 baud; rows 54; columns 120; line = 0; | intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; | stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0; | -parenb -parodd -cmspar cs8 -hupcl -cstopb cread -clocal -crtscts | -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -ixon -ixoff -iuclc -ixany -imaxbel iutf8 | opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 | isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke -flusho -extproc | rc=0 Leslie -- Platform: Linux Distribution: openSUSE Leap 15.4 (x86_64) java version "19.0.1" 2022-10-18 Java(TM) SE Runtime Environment (build 19.0.1+10-21) Java HotSpot(TM) 64-Bit Server VM (build 19.0.1+10-21, mixed mode, sharing) NetRexx portable processor 4.05-beta build 62-20230422-0022 |

I'm having another try at a multistream pipeline, but whatever I try, pipc chokes on one thing or another. I've attached the GenSymLinks.njp source that's bugging me; it has comments about what goes wrong with the three possible versions of the pipeline (Portrait with trailing stageseps, Portrait with leading stageseps, and Single-line). Obviously I'm doing something wrong, but though I've read through the Pipeline Guide and Reference over and over, I can't see what. The Single-line pipeline compiles as a literal presented to pipc, but compiling the GenSymLinks.njp doesn't seem to like any code that follows any of the three pipeline versions. If it works for you, there must be something wrong with my NetRexx installation. (By the way, thank you so much for the enhancements to the specs stage.)

Hi, Now that I'm looking at the right version of the (PDF) books, I notice a few things: * In the Pipelines Guide and Reference, the description of the specs stage overflows over the definitions of spill, split and sql (see attached). * In the NetRexx Language Reference, the description of the stream() method seems incomplete, with merely an implication that the OPEN operation can have other modes than R/W, though one can use at least OPEN READ; I have not explored whether WRITE, APPEND, SHARE are also allowed.

<p>I have just released an extension to the NetRexx Pipelines <b>PARSE</b>
stage, together with tests and documentation. It should be in the
next release.</p>
<p>Note: This changes the variable names from "$1" through "$9" to
"_1" to "_9" to avoid a NetRexx internal name conflict.
$-variables are depreciated, but will, for now, work in existing
pipes<br>
</p>
<p>It extends the current <b>parse</b> stage from just input and
output templates to include a optional <b>netrexx</b> (or <b>nr</b>)
delimited string of one or more NetRexx statements between the two
templates. Also a <b>finally</b> delimited string of
statements. This greatly increases the power of this stage. <b>Parse</b>
stage is only NetRexx Pipelines, not CMS.<br>
</p>
<blockquote> /** parse -- Rearrange Contents of Records using Rexx

<font face="Cascadia Code">

<font face="Cascadia Code">
+-FINALLY-finally_NetRexx_Dstring-+</font><br>
<br>
Records are parsed via the parse_template_delimited_string.<br>
Variables are named _n, where n is 1 to 9.<br>
The values of the variables are put into the
output_template_delimited_string<br>
replacing _n.<br>
For a literal _n that won't be changed, use __n.<br>
The NetRexx_Dstring and finally_NetRexx_Dstring are any valid
NetRexx statement<br>
or ;-separated statements that may use and set the ""_n""
variables.<br>
The string \n will split the string into separate output records.<br>
The special indexed variable COUNTER[] is also available in these
Dstrings.<br>
Note: Now depreciated: "$n" instead of "_n"; no NR or FINALLY.<br>
<br>
Examples:<br>
parse / 2 _1 +1/ /The second letter is \"_1\". __1 won't be
changed./<br>
<br>
parse / _1 2 _2 +1 _3/ NR /_2 = _2.upper/ /_1_2_3/<br>
<br>
PARSE /_1 2 _2 +1 _3/ ,<br>
NR /if _2.datatype('l') then counter['c'] = counter['c'] + 1;
_2 = _2.upper/ ,<br>
/_1_2_3/ ,<br>
FINALLY /return counter['c'] 'changed to upper'/<br>
<br>
parse /2 _1 +1/ NR /counter[1]=counter[1]+1/ FINALLY

<p>This works to display, via SAY, the diagram and notes (more info

<p>I have pushed a new NetRexx Pipeline stage and tests: DELAY. It

<ul>
<li>(1) Arguments are NetRexx Pipelines only, not CMS. CMS (and
NetRexx when there is no argument) reads delays as the first
word of each record. <br>
When arguments are present, they follow the CMS conventions
for the delay time in records. The + indicates a duration, no
+ means time of day. The objects do NOT have the delay as the
first word. <br>
Clock hours are 24h, so 2pm is 14, and are for the next 24
hours if before "now." <br>
Seconds can have decimal point and milliseconds. <br>
In relative times, the number of seconds and minutes are not
limited to 60; so 120 seconds is the same as 2 minutes.</li>
<li>(2) Used only for "relative time." EACH, the default, delays
before each object; ONCE delays only the first object.</li>
<li>Uses Java's Thread.sleep() method and may not be exact in
fractional seconds.</li>
</ul>
</blockquote>
<div>
<div class="p-note">When in the records, the time must be a single
word. As arguments, it is tolerant of spaces.</div>
<div class="p-note"><br>
</div>
<div class="p-note">The submitted tests include only "relative
times" not clock times, and do not test for the actual time of
delay.<br>
</div>
</div>
<p>This will be used in some stage tests, where NetRexx's
multi-streaming can cause race conditions.</p>

<p>For testing a pipeline's arg() feature using the {} style, I wish
to have a pipe stage like this to be taken, well, literally:</p>
<blockquote>
<p><font face="monospace">literal {avar} |</font></p>
</blockquote>
<p>but this gets interpreted.</p>
<p>Is there a way I can "escape" the "{" so it is just another

<p>In building a new <b>HELP</b> stage, and wanting to handle all
the stage names and their synonyms, I have run into a problem with
an argument of just the question mark: "?", which is a synonym for
<b>HELP</b> in CMS.</p>

which is processed all right. But with the character <b>?</b> ,
it never gets through.<br>

<p>So, NetRexx alone is not "eating" the "?" parameter, it must be

<p>René,</p>
<p>I continue to get the error. I even downloaded the version of
help.nrx from SourceForge and recompiled with that.</p>
<p>What I have done is go ahead with an AHELP stage, and the
individual stage methods as givehelp(). That is working fine for
me. I have also added in the special terms as methods within in
AHELP, so</p>
<blockquote>
<p><font face="monospace">pipe help delimitedstring</font></p>
<p><font face="monospace">pipe help delimited string</font></p>
</blockquote>
<p>work as well.</p>
<p>I have an edit macro that does most of the work to convert the
railroad diagrams to text. I am adding a few things in from the
manual.</p>
<p>I'd still like to get the DISPLAY stage working, but it looks
like it is out of my hands.<br>

<div>My conjecture: somehow we confused the compiler by naming

<div>we have an INSIDE stage, so I would skip all
quoting and continuing and pick the right lines
out of a file with INSIDE - then you can use the
class-level help() to call super.help(stage) and
have that deliver the lines.</div>

<p>Looks great. I'll explore it more
later today. Then get to the stage
files. Most of them have the railroad
diagram in a comment, so it means moving
that to the new help() method. I do
wish NetRexx had a multi-line quote for
this, but adding quote marks and a
continuation character to each line
should do the trick. (The <b>help</b>
stage will need some special work so
this method is not taken as a
constructor.)<br>

And you should use getMethod instead of
getDeclaredMethod if you want to inherit
the help() from stage - the superclass,

the best solution for the

We can load the stage class

you pass in the (short) stage
name, complete its name in the
class.forName method, which
leave a Class object in
variable stageClass. We ask
that Class object to return
the help() method in the
variable helpMethod. On that,
we invoke it with no
parameters, it returns the
help message from the static
help() method.</div>

about
enumeration of

approaches. We

NetRexx build
time,
enumerate all
the built-in
stages into a
structure.
That might be
the most
efficient and
straigtforward
way. We could
also do that
dynamically;
if the
compiler can
do it, we also
could. This
might be more
involved and
would take
slightly
longer.</div>

<p>René,</p>
<p>Yep,</p>
<p>I get it to work with the stage name <b>AHELP</b>, which in CMS
is an almost alias for <b>HELP</b>. <br>
</p>
<p>I tried to make a HELP class that extends AHELP, but it gives the
same error. I then removed all "help.*" files from both <b>src</b>
and <b>build</b> directories then rebuilt. Only to get the same
error. It seems there must be a <b>help</b> class somewhere else
in Java/NetRexx.</p>
<p>A solution (?) might be to have the <b>AHELP</b> as a standard
stage class and in the pipeline scheduler make a stage alias for <b>HELP</b>,
like we do for <b>></b>.</p>
<p>While I'd like to be able to use a DISPLAY stage for all the
fancy HTML stuff, for now I'll go for plain text via SAY. And
continue working in that direction.</p>
<p>Thanks for all your help.</p>
<p>Jeff<br>

Hi Jeff,
<div><br>
</div>
<div>I checked in a working help stage.<br>
<div><br>
</div>
<div>My conjecture: somehow we confused the compiler by naming
both the class 'help' and the method 'help'. The latter
returns a type Rexx.</div>
<div>My first reflex was to call your class 'helo' and then it
works when starting a </div>
<div><br>
</div>
<div>pipe "helo crc | cons"</div>
<div><br>
</div>
<div>but because 'helo' is not a good name for a help stage, I
renamed it back, and changed the help() method on class stage
and class crc to 'giveHelp'.</div>
<div><br>
</div>
<div>Somehow someone took a shortcut somewhere. Line 50 must be
from the generated stage source. Do we accept this or do we
open an issue to go to the bottom?</div>

<div>we have an INSIDE stage, so I would skip all
quoting and continuing and pick the right lines
out of a file with INSIDE - then you can use the
class-level help() to call super.help(stage) and
have that deliver the lines.</div>

<p>Looks great. I'll explore it more
later today. Then get to the stage
files. Most of them have the railroad
diagram in a comment, so it means moving
that to the new help() method. I do
wish NetRexx had a multi-line quote for
this, but adding quote marks and a
continuation character to each line
should do the trick. (The <b>help</b>
stage will need some special work so
this method is not taken as a
constructor.)<br>
</p>
<p>Thanks!</p>

And you should use getMethod instead of

the help() from stage - the superclass,

the best solution for the

stages package is available.
We can load the stage class
with the Java Reflection API,
and then call (invoke) the

you pass in the (short) stage

leave a Class object in

that Class object to return

we invoke it with no

about
enumeration of
the stages: we
have several
approaches. We
could, at
NetRexx build
time,
enumerate all
the built-in
stages into a
structure.
That might be
the most
efficient and
straigtforward
way. We could
also do that
dynamically;
if the
compiler can
do it, we also
could. This
might be more
involved and
would take
slightly
longer.</div>

Hi Jeff,
I checked in a working help stage.
My conjecture: somehow we confused the compiler by naming both the class 'help' and the method 'help'. The latter returns a type Rexx.
My first reflex was to call your class 'helo' and then it works when starting a
pipe "helo crc | cons"
but because 'helo' is not a good name for a help stage, I renamed it back, and changed the help() method on class stage and class crc to 'giveHelp'.
Somehow someone took a shortcut somewhere. Line 50 must be from the generated stage source. Do we accept this or do we open an issue to go to the bottom?
best regards,
René.

<p>Looks great. I'll explore it more later today. Then
get to the stage files. Most of them have the
railroad diagram in a comment, so it means moving that
to the new help() method. I do wish NetRexx had a

(short) stage name, complete its name in the
class.forName method, which leave a Class
object in variable stageClass. We ask that
Class object to return the help() method in
the variable helpMethod. On that, we invoke
it with no parameters, it returns the help
message from the static help() method.</div>

about enumeration of the
stages: we have several
approaches. We could, at
NetRexx build time,
enumerate all the built-in
stages into a structure.
That might be the most
efficient and straigtforward
way. We could also do that
dynamically; if the compiler
can do it, we also could.
This might be more involved
and would take slightly
longer.</div>

rerouted answer to pipelines list:
Jeff,
we have an INSIDE stage, so I would skip all quoting and continuing and pick the right lines out of a file with INSIDE - then you can use the class-level help() to call super.help(stage) and have that deliver the lines.
(In there we can test the terminal for graphic ability and deliver the optimal graphics - more than one terminal can do SVG nowadays).
best regards,
René.

I do wish NetRexx had a multi-line quote for this, but adding quote marks and a continuation character to each line should do the trick. (The help stage will need some special work so this method is not taken as a constructor.)

<p>On investigation, the problem has nothing to do with
hexadecimals, bad or otherwise.</p>
<p>It is actually a <b>Syntax Error</b>. The <b>XLATE</b> stage
does not and never was supposed to support a <b>ws</b> option.</p>
<p>I have fixed the stage so it reports this, and others, as a
Syntax Error:<br>

Hi Marc, no, this is no good and needs fixing. On VM Pipelines the output is the same as the 4-10 case: none. So we have something to trace and fix. If you could open an issue at https://github.com/RexxLA/NetRexx/issues then whoever is going to work on it can assign themselves and avoid we are doing duplicate work. If I am going to fix it, I will check the issue first. best regards, René. > On 6 Feb 2023, at 12:03, Marc Remes <re...@gm...> wrote: > > Is this expected behaviour?

Is this expected behaviour?

And diskr.nrx (the diskr stage) has plenty of RC 13
In this case it is
catch FileNotFoundException
-- say 'File 'Arg()' Not found'
Emsg(13,'Error - File "'file'" not found')
Still trying to understand this pipelines thing..
