[VW 7.5] [Mac OS X] Opening default mail program using "open mailto:...", with bash

Hi,

I’m still trying to get the default email program to open using open mailto: etc.

After getting a 0: Event not found, when using cshOne: I figured I needed to use the bash shell.

So I created (based on cshOne:)

bashOne: string

"Invoke a bash-shell, pass it the string as a command and return the

result (a String)."

"UnixProcess bashOne: 'ls -l'"

| cmd proc reply connection |

connection := self pipeConnectionFor: 'bash'

arguments: #('')

setProcessDescriptor: [:pd | proc := pd].

cmd := connection readAppendStream.

[cmd nextPutAll: string; cr; commit.

reply := cmd contents.

proc wait]

ensure: [cmd close].

^reply

Sadly this doesn’t work. If I copy the string as passed in and past it into a bash shell, the mail program opens ok.

I’m thinking that I need to pass some arguments to the pipe connection, but not sure what. (I don’t unix often).

Any help greatly appreciated.

Cheers,

Stewart

Basically one doesn't need any shell at all when you're not doing
any command line tricks with redirections or pipelining. I've got a
#runProcess in my repository that just invokes whatever you want
directly, I'll send it to you when I'm back home (now in Monaco on
a consulting gig). Though I've posted that to this here list about
a year ago, you might be able to find it in the archives if you're
in a hurry.

Though that doesn't quite explain why your example doesn't work.
The only thing I see is that you use "bash" without an absolute
path, try maybe "/bin/bash".

Ah, hold on a sec... You aren't using things with exclamation
marks in your command? The exclam is a magic thing in csh that invokes
the command history and it will complain if it doesn't find something:

% !foo
foo: Event not found.

Escape it with a $\ to disable that or put the argument in
question under quotation marks. That's another problem with cshOne,
since it's a shell, it reacts to all things shell.

Cheers,

The original cshOne: use '-t' option telling the shell to take a single
command input line from standard input. I don't know if this is a
possible option of bash...

In your case, you have a single command to execute, the simple thing to
do is to execute bash with two arguments:
'-c' and 'your_mail_command_here' (the string argument).

bashOne: string
"Invoke a bash-shell, pass it the string as a command and return
the result (a String)."
"UnixProcess bashOne: 'ls -l'"

| cmd proc reply connection |
connection := self pipeConnectionFor: 'bash'
arguments: (Array with: '-c' with: string)
setProcessDescriptor: [:pd | proc := pd].
cmd := connection readStream.
[reply := cmd contents.
proc wait]
ensure: [cmd close].
^reply

Maybe you can inquire option '-s' but I'm not sure I understood all the
tricks the shell plays to connect to a tty or use the stdin instead...

Here's the code I use in our GNUPlot parcel:

plot
"
Returns the output stream (a ByteArray) from running the gnuplot
program.
"
| connection proc reply |
connection := UnixProcess
pipeConnectionFor: 'gnuplot'
arguments: #('-persist')
setProcessDescriptor: [:pd | proc := pd].

[connection output writeAll: (self plotCommand

replaceAll: Character cr
with: Character lf;
readStream) upToEnd.
connection closeOutput.
reply := connection input readStream
binary;
upToEnd.
proc wait] ensure:
[connection
closeOutput;
closeInput].

Here's another, similar one with more parameters for greater flexibility:

binaryOutputFrom: aName arguments: anArgv inputStream: aStream
"
Create the subprocess 'aName' and pipe to its stdin the data from
aStream, and return the subprocess' output as a ByteArray.

If your subprocess' input stream requires special end-of-line
characters, don't forget you may have to
buffer replaceAll: Character cr with: Character lf
before building a stream on it and passing it here.
"
| connection proc reply |

connection := UnixProcess
pipeConnectionFor: aName
arguments: anArgv
setProcessDescriptor: [ :pd | proc := pd ].

[
connection output writeAll: aStream upToEnd.
connection closeOutput.
reply := connection input readStream binary; upToEnd.
proc wait
] ensure: [
connection
closeOutput;
closeInput
].

Hi Martin, Nicolas, and Thomas,

Thank you all for replies. I haven't had a chance to try your
suggestions out on my friend's machine as yet.

However, I'm thinking that I'm mistaken in thinking I need to use bash.
The reason being is that I have used csh: to open the default web
browser, so that must be working. Also, I think Martin has identified
the problem - even though I had encoded the "url", it did contain an
exclaimation mark. Which accounts for the 0: Event not found answer.

I'll let you know once I get a chance to test this hypothesis.

Cheers,

Stewart

Success! As Martin suspected... the exclamation mark was the problem!

Thanks to everyone for your suggestions and help.

[VW 7.5] Fonts & glyphs problem...

I'm having problems getting VW to render glyphs, especially when using
greek, symbol and math fonts. To check, I used this code fragment from a
workspace:

gc := (ExamplesBrowser prepareScratchWindowOfSize: 200@600) graphicsContext.
ts := TextStream on: String new.

range := 16r00 to: 16rFF.
1 to: range size do: [:index | ts nextPut: (range at: index) asCharacter.
(index rem: 10) = 0 ifTrue: [ts nextPut: Character cr] ifFalse:[ts
nextPut: Character space]].

pS := 16.
fd := (FontDescription new)
family: #('symbol');
pixelSize: pS.
style := TextAttributes defaultFontQuery: fd.

"20% leading (the usual amount)"
style lineGrid: (1.2 * pS) ceiling.
ct := ComposedText withText: ts contents style: style.
ct displayOn: gc at: 5 @ 5.

The output I get in the scratch window is, well, quite different from
what you get when looking at e.g. the character map on WinXP (c.f. the
two screen shots).
Does anybody have any suggestions, remedies,...???

...the same problems crop up when working on MacOS 10.4.9, so I don't
think it's (only) platform/OS related
