[Boa Constr] Boa: first impressions

[Carlos R. <cri...@ma...>]

Well, I've just downloaded a CVS snapshot of Boa (version 0.1.3, I think). I 
would like to contribute with my first impressions. Some personal info 
first... I have a *lot* of experience with Delphi (since the first betas, 
pre-1.0).

- Boa is really nice and well structured. But documentation is lacking; I 
could not access any help information. I assume some doc is already 
available, but I don't know how to download it from CVS.

- For people used to popular two-way RAD GUI tools (such as Delphi and VB), 
the 'commit'/'cancel' nature of the Frame Designer looks strange at first. 
[In Delphi, the source code is automatically updated when you drop a 
component on the designer view]. But it works nicely, and it does not 
seriously affect productivity - it's just a matter of adaptation.

- The Frame Designer has a few problems, though. Some components proved 
difficult to select once put onto the designer., specially static text boxes. 
I tried clicking the mouse on some locations, but could not select it. Moving 
an edit box (the one called 'wxTextBox') was also difficult, but I managed to 
make it.

- I could not select more than one component at a time. Is it a 'feature', or 
is it going to be fixed?

- Changing the structure of the form also proved to be a little bit difficult. 
For example, I would like to put some components that were designed into the 
form inside a panel (I forgot to add the panel first :-) I know how to 
convince Delphi to let me do just that; not only cut & paste works fine in 
Delphi for multiple component selection, you can easily edit the form 
description, which sometimes is better than the visual form designer for some 
changes.

- I took a look at the code generated by Boa. I guess that the code was 
intended for processing by Boa alone, but it would not hurt if the code was 
formatted a little bit better. Breaking the long lines would help a lot for 
us to read and understand what's going on.

- Probably, my main gripe is with the lack of online documentation for the 
wxWindows library. I have heard how good wxWindows is, but a better 
documentation is really needed. I sincerely don't know where to start, and 
please bear in mind that I'm no novice in this stuff.

- Last but not least, I could not debug my first app and I have no idea why. I 
just clicked on the 'debug app' button, the mouse cursor went clocking, and 
Boa just froze - no redraws, no response to any command. Had to kill -9 it.

- Back to the textual description of the form, as available in Delphi... and 
to the code generated by Boa. I think that it would be interesting to 
describe the components using a dictionary, and then feeding this dictionary 
to a initialization procedure that would create the window using the 
information. It would make reading/editing the properties of the visual 
components a little bit easier. Form creation could be slowed down a little 
bit though. I assume that this topic was already discussed on the list 
before, could someone give me a few pointers?

- Back to the wxWindows documentations issues: one of the main problems with 
GUI libraries is that it's not enough to know the library functions; one has 
to understand how things do fit together, how do they interact. I'll give one 
example.

I know that wxWindows has some layout classes. The application that I am 
designing now calls for relatively complex windows, with panels with grids 
and buttons to act on particular records shown on those grids. The basic 
point here is that the window has to be structured the right way. In Delphi, 
I developed my own way to make it work - I make extensive use of panels as 
containers for rows of buttons, pseudo-title-bars for sections of the form, 
etc. The question is, is this the correct technique for wxWindows? 


Many thanks for the dev guys for Boa - it's already in a pretty usable state, 
and it will help me to write my new Python app very, very quickly.

[Boa Constr] RE: Newbie problem with fonts on RH8 - Solved

[Eric W. <ewa...@ya...>]

Thanks Gerrit, that solved my problem.  Sorry I didn't find the message in
the archives myself.

FWIW, I added something like the following line to my ~/.bashrc file:

alias boa='env LANG=en_US /path/to/python /path/to/Boa.py'

Now when I want to run boa constructor, I simply type 'boa' at the command
line and I'm all set.

Best regards,

Eric.

When using the default ....utf8 locales, characters will
display as junk. The short term remedy is to set the
LANG variable to en_US or whatever you need instead of
en_US.utf8

Well, my experience with OpenSSH under cygwin is very
good. One fine thing is that it supports ssh-agent.
This will work with any process, given that you start
it from a cygwin shell.
For instance, I use it with WinCVS. Starting a cygwin shell,
I run

ssh-agent bash
ssh-add   (type your phrase)

and then I call the WinCVS executable from that shell.
Works fine, authentication works behind the scenes
like a charm.

I haven't seen a package yet that does this for plain
windows, alone.

[Boa Constr] Newbie problem with fonts on RH8

[Eric W. <ewa...@ya...>]

Hi All,

I'm a boa constructor newbie.  I have boa installed and running nicely on
a RedHat 7.3 (upgraded to RH8) box and on Windows 98.  I've an application
that runs nicely on both these boxes.  On a new IBM Thinkpad A31 with a
fresh install of RedHat 8 I'm having trouble with what I think is a font
problem.  In a nut shell, all the source code is invisible and some of the
text in the  "File Open" dialog is unreadable.  Each character looks like
a box made of dashed lines.  What's strange is that some of the text looks
fine but some looks like these little boxes.  Please see the screen shot
to see what I mean.

Thanks for any pointers you can give.

Eric.  

I've posted a screen shot of the problem here:

   This is a difficult problem to solve completely because the set of fonts
commonly available on Linux is different to Windows. It may be best to
explicitly choose fonts depending on platform. This is how Boa itself
handles the problem:

common.defs.msw={'size': 10, 'backcol': '#FFFFFF', 'ln-font': 'Lucida
Console', 'mono': 'Courier New', 'ln2-size': 7, 'plaintext-size': 10,
'ln-size': 8}
common.defs.gtk={'mono': 'Courier', 'ln-font': 'Helvetica', 'size': 12,
'ln-size': 10, 'backcol': '#FFFFFF', 'ln2-size': 9, 'plaintext-size': 12}

   There are a few names that have approximate equivalents (Arial,
Helvetica, Helvetic, Helmet, Geneva), (Courier, Courier New), (Times, Times
New Roman, Timmons).

   Overhead isn't much of a problem. The problem is the dearth of high
quality *hinted* outline fonts on Linux. There are actually quite a few good
outline fonts bundled with Linux distributions or available on the web which
look great in large sizes or when printed but look poor on the screen due to
lack of hinting. For personal use many download Microsoft's core web fonts
from http://corefonts.sourceforge.net/ and then use these on Linux. However,
there are distribution restrictions that make it difficult to use these in a
product.

[Boa Constr] Anyone have advise with cross platform fonts?

I use Boa to develop on NT, and Linux is the deployment platform.  One

One of the constraints I try and keep is using mono spaced, bit map
fonts.  I do this because I believe this minimizes the overhead.

Kingsley,

Are you running the CVS or the Tarball version? Also
what version of wx are you running. I remember getting
that error when I upgrated to wx 2.3.3, but the latest
CVS versions dosn't have this problem. (instead mine
crashes at a later stage).

[Boa Constr] Segfaulting in CVS version

[Nigel S. <nig...@ya...>]

Hi,
I just CVSed down the boa so I could run it with
wx2.3.3. However when boa is starting it segfaults
just after it loads Editor. By a process of placing
print statements through the code I have found the
offending command is line 667 of
Views/StyledTextCtrls.py. The line reads as follows. 

        self.language = language
        (cfg, self.commonDefs, self.styleIdNames,
self.styles, psgn, psg, olsgn,              olsg, ds,
self.lexer, self.keywords, bi) = \
              self.getSTCStyles(config, language)

Any ideas as to the cause, fix, etc... I am using
python 2.2.2, all from the unstable debian tree.

Thanks

Added -rf, thanks.

Opening files works for me.

From the error message it was trying to open folder/test.txt from
a SSHConnection named "label~". I doubt you actually had a 
SSHConnection named like that so the URL splitting logic is somehow
not handling your path.

Please mail me (directly) your connection info (from Explorer.msw.cfg).
Remove sensitive info.

Also note something I failed to mention before; you may now safely 
remove the scp_pass property from any SSHConnection definition
in Explorer.msw.cfg.

As a workaround for now, use A simple alpha-numeric connection 
name and avoid ~ (I don't know why it would break anything, but
"label~" seems to indicate it as a possible culprit)

>

You mean when you copy/paste from one SSHConnection to another?

That's not supported no.

scp does not seem to support copying from one remote server to another.

If you are interested:

SSHExplorer.SSHExpClipboard.clipPaste_SSHExpClipboard

must:
* Check if the pasted node is from a different SSHConnection
* SCP it to a local temp file
* SCP the temp file to the second remote server.

I've no plans to do this soon.

I've added this. (untested, please test)

PySSH, maybe not too much pain :)

At the end of this thread Boa no longer supported putty, so that 
doesn't bother me :)

Personally I don't want to tie Boa to cygwin. Can't your library also 
use a single ssh.exe/scp.exe setup. (I can mail these exes to you if 
you don't have them)

I will put PySSH integration on my todo list, but be warned the list 
is huge so I won't get to it anytime soon.

I strongly urge you to attempt the integration!

Make a copy of Explorers/SSHExplorer.py and call it 
Explorers/PySSHExplorer.py. Keep all the class names the same.

In Explorer.*.cfg, in the installedtransports list under the 
[explorer] section, just change 'Exporers.SSHExplorer' to 
'Exporers.PySSHExplorer'.
Now the PySSHExplorer will be a drop-in replacement for SSH.
I assume for your purposes the current connection properties
will be sufficient.

You don't have to know about the rest of the Boa code base to 
implement this, just reimplement the current interface.

One small complication is that SSH support (like most others) is
currently a stateless transport. Only the FTP transport is statefull.
You'll have to use tricks similar to FTPExplorer to automatically
do the connection when necessary.

Perhaps Riaan could have a look at PySSH 
(http://sourceforge.net/projects/pyssh).  This makes it relatively easy to 
send a number of commands over a single SSH session, and view (from within 
Python) the output.

It is still Beta, but should work well with ssh on Linux and on Windows using 
Cygwin.  It does support Putty on Windows, but that is still Alpha, although 
its main shortcoming is in forcing the SSH session to close.

I am the current maintainer (took over in August this year), and if there is 
interest and feedback I'd be fairly likely to put in the work to get the 
Putty integration up to the desired level.  OTOH, in my experience ssh under 
cygwin is more powerful than putty for command line usage, and in this case 
pyssh should work well.

By the way, Boa rocks big time.  I used it while writing pyssh 0.2.

Rasjid.

Hi Riaan!

Much better now. The discussed problems are solved!


But I found some other bugs:

1.) Deleting folders doesn't work with 'rm'. What about using 'rm -r' or 
'rm -rf'?

2.) Opening files doesn't work:
Explorers.ExplorerNodes.TransportError: Catalog transport could not be 
found: label~ || folder/test.txt

3.) scp from one remote host to another doesn't work.

4.) The irix host returns folder names with trailing slash. The explorer 
shows "./", "../", "folder/" and the paths contain "//". I don't know 
how many unix platforms do this, but filtering out trailing slashs would 
be nice.

Connecting and authenticating seems to be an expensive process: About 30 
seconds on my accounts. So browsing doesn't make much fun. Whould it be 
possible to keep the ssh connections alive? Perhaps in a future release?

have guessed, but I suppose it makes sense.

This is the one I'm going to use, thanks for the testing!

(after testing)

Damn! This does not work for the source forge server.

This variation does work (I'm now using it):

[user@windowshost]: ssh -l <user> <linuxhost> ls -la '~/folder'

I've added quoting to all SSH commands that uses paths.

My comment above was under the assumption that your OpenSSH accepted 
windows paths. If it doesn't, then agreed, more than just the above 
changes are needed.

Understood, although the @ could be used to distinguish between 
local and remote parts.

pscp handles local windows paths correctly.

> Any hints where to change the local path?

When I implemement the proposed "current directory hack" there will
be no more local paths only a filename ;)

...

Ok, all discussed changes are implemented, tested and checked into CVS.
Please also test and drop me a note if it doesn't work as expected.

I have *many* other local changes to other parts of Boa, but have 
not had time for a mega checkin, hope to get to it soon!

Thanks for the feedback,
Riaan.

Hi Riaan!


Many thanks for your reply!

Interested in some more test results? Today I took a closer look at SSH.

I tested on 3 accounts:
user@irixhost: irix, OpenSSH
user@linuxhost: linux, OpenSSH
user@windowshost: windows, OpenSSH/cygwin, boa

Right.

Yes and no.

The '~'-problem:
================
~ is expanded on the local machine. If home path is not the same on 
local and remote machine, SSHExplorer fails.

[user@irixhost]: echo $home
/home/u/user
[user@linuxhost]: echo $home
/home/user
[user@windowshost]: echo %home%
C:\myhome

[user@irixhost]: ssh -l <user> <linuxhost> ls -la ~
ls: /home/u/user: not found
[user@windowshost]: ssh -l <user> <linuxhost> ls -la ~
ls: /myhome: not found

[user@irixhost]: ssh -l <user> <linuxhost> ls -la \~
works
[user@windowshost]: ssh -l <user> <linuxhost> ls -la \~
ls: ~: not found

[user@irixhost]: ssh -l <user> <linuxhost> ls -la '~'
works
[user@windowshost]: ssh -l <user> <linuxhost> ls -la '~'
works
[user@windowshost]: ssh -l <user> <linuxhost> ls -la '~'/folder
works
[user@windowshost]: ssh -l <user> <linuxhost> 'ls -la ~/folder'
works

Quoting seems to be the solution, at least on cygwin and unix. Changed 
the property 'root' from "~" to "'~'" and browsing works fine for me.

Same Problem with OpenSSH.

Well. Actually that's the last thing I tried before writing to the 
mailinglist.

The ':'-problem:
================
scp syntax uses ':' to seperate <host> from <file>. c:\filename is 
interpreted as host = "c" and file = "\filename".

[user@windowshost]: scp <user>@<linuxhost>:file c:\folder
ssh: c: no address associated with hostname.
[user@windowshost]: scp <user>@<linuxhost>:file /folder
works
[user@windowshost]: scp <user>@<linuxhost>:file /cygdrive/c/folder
works

Any hints where to change the local path?

I assume you mean you changed the property 'root' of the SSH 
connection.

You *should* change this (as you did) to wherever you need.
It's a property in the Inspector after all!
~ still sounds like a valid default that has a better chance
of working that any other default value.

>      o  changing 'ls %s -la' to 'ls -la %s' in the source

It worked for me, but yes, 'ls -la %s' is better (at least that's 
the way I usually list files ;)

Yes, it's putty scp. The only scp I could get to work (see below).

The browsing part should work. The copying part won't (as it is 
currently).

As these tools are actually unix tools, there is no reason
for it not to work there if you change the strings in the
buildSCPStrs method.

I've actually forgotten about this issue (pscp) thanks!
In my defence, this is the first feedback I've received about SSH 
support.

Under 2.3.3.1/wxGTK Boa's SSH support is currently broken on unix 
anyway due to different issue (Problem with wxProcess and it's streams)
so you won't even get this far.

> - Why do I need scp_pass? scp does key authorization like ssh.

Mine doesn't, not exactly the same.

The biggest issue (if I recall correctly) was that scp always 
prompts for a password/passphrase and would not use the stored key
without prompting.

When running it from another process, It is impossible to 'feed' 
scp a password/passphrase on stdin as password input is handled 
handled differently by the shell than normal input.
(With a blank passphrase and the identity file ssh does not prompt)

That's why I chose pscp that accepts a password on the command line.

(later, the above left in for historical purposes ;)

After testing scp again it seems to be working now! 
Granted I'm not on the same machine I was when I wrote SSHExplorer,
but I have no idea what has changed in the meanwhile.

The new problem I now have is that scp does not accept windows 
paths. (Seems to be a quick and dirty port)

e.g. 
scp <remotepath> text.txt

copies fine, but

scp <remotepath> c:\text.txt

gives an error :/

One way to work around this would be to change the current directory 
to the localpath directory before running the command.

(later again)

Ok I installed the OpenSSH that you are using (I think).

It was unable to use my current public/private keys so I uninstalled it. 
I'm *not* going thru that whole new key process now.
(Also it's cygwin based and I really prefer the simple 
 scp.exe/ssh.exe setup I had)

I'll implement the current directory hack, that should work for both 
of us and also on Linux.

For you this change should be sufficient:

    def buildSCPStrs(self, source, dest):
        return 'scp %s %s'%(source, dest), 'scp %s %s'%(source, dest)

Cheers,
Riaan.

I'm being silly, Ok, found it, managed to compile with --disable-joystick
(no big loss here). Unfortunately wxPython 2.3.2 is nowhere to be seen,
only 2.3.2.1 which doesn't compile.

Nevermind, I think I'll have to pass on this one for the time being :-(

Dig to understand how it works. As I said I am just starting to learn Python.

As somebody else already pointed out, at least in RedHat 8.0 this is in
the python-devel package.

Thanks again for your prompt replies :-) Faster than the speed at which
I can digest them :-)

[Boa Constr] SSHExplorer

[Yuppie <sc...@we...>]

Hi!


Does anyone use the SSHExplorer?

My environment:

- Boa 0.1.3 a
- Windows 98 SE
- OpenSSH on Windows v3.4-2

My experiments:

- I managed to browse the remote filesystem
     o  using the absolute root path ("/home/user", not "~")
     o  changing 'ls %s -la' to 'ls -la %s' in the source
- I tried to open files from remote filesystem
     o  copyToFS and copyFromFS seem to use pscp, not my scp

My questions:

- Is pscp PuTTY-scp? Does SSHExplorer work if I install this?
- So SSHExplorer doesn't work on unix platforms?
- Why do I need scp_pass? scp does key authorization like ssh.


TIA,

Yuppie

You just need to install the python-devel rpm.

Like I said, these are optional example components. (not Boa spesific)
The bcrtl also contains COM components which you certainly don't need ;)

> I know it can be disabled but I don't understand yet how important it is.

The plug-in under: Plug-ins/UserCompanions.plug-in.py defines the Boa 
wrappers so that these components can be created from the Palette.

Hint: To disable a plug-in, rename the file, I rename them to e.g.:
Plug-ins/UserCompanions.plug-in.disabled.py

Boa itself does not rely on them.

> Does it require write access all the time or just once to install its stuff ?

If the preference to installBCRTL is on, the filedates are checked
at startup and updated if needed, but if you aren't editing them,
it will only copy them the first time.

> Can it be installed somewhere in user's directory ?

Not currently no, the bcrtl components generate source like this:

from wxPython.lib.bcrtl.user.ExampleST import *

Dig for what? :)

This is the error I get when I try to build a Boa rpm:

distutils.errors.DistutilsPlatformError: invalid Python installation:
unable to open /usr/lib/python2.2/config/Makefile (No such file or
directory)

Which is completely true, I have binary rpm installation of Python,
but surely you don't need to build you own Python before you can 
build rpm files with distutils!
