Be aware that you complete the PATH variable as the script isn’t executed in an interactive shell. This means no .bashrc or .profile are read. So you have to set PATH by yourself. You also have to pay attention to the order of the binary locations. I had some trouble with the Leopard¹ svn installation and the macports installation. The former was an older version which couldn’t work with repository created by the latter.

If you get one of these error messages

svnlook expected fs format '2'; found format '4'

or

Invalid change kind in rev file

take a look at the PATH before you start debugging svn2web

For those who want to set ftp/sftp options you can do this by setting the svn property svn2web-options. Unfortunately this is nowhere documented so if it’s not working properly you should contact the dev team or fix it by yourself. Don’t forget to spread the bugfix with the world.

The usage of this library collection requires some work. In fact you only need to include functions.core.php and the libraries you need. But to find out what files you exactly need can be hard because some functions have a lot of dependencies so my proposal is to include everything as you needn’t to care about any dependencies later on.

Furthermore some files have to be included exclusive-or what means that either the one has to be included or the other one. Download backpress.php and include the extracted file in your web project.

1. Convert the uploaded pdf files to postscript

for file in `ls -1`; do pdftops $file; done

ls -1¹ lists all the files of the current directory, one file per line. pdftops actually converts the pdf files to postscript.

2. Delete the pdf files

rm *.pdf

We need to delete the pdf files to only list postscript files in the next command.

3. Put two pages on one page and print them

for file in `ls -1`; do psnup -2 -d0 $file | lpr -Pscit32411d; done

Again we walk through the file list but this time psnup prints two pages on one page and we pipe its result to the print command lpr. The argument P is the printer name of our destination.

I’m sure this can be done in only one line but I’m not a big shell scripter so I make the batch printing in three lines.

An escaped space character caused svk fail the check:

if substr( $source_path, 0, length( $source_root ), '') ne $source_root;

in line 162 in SVNRa.pm.

I fixed this problem while adding a line which replaces %20 by a space character because an URL with the file protocol must not be escaped. These resources are accessed directly from the disk and not from a webserver.

$source_path =~ s/ /%20/g if $source_path =~ m,^file://,;

# XXX: this shouldn't happen. kill this substr
die "source url not under source root"
if substr( $source_path, 0, length( $source_root ), '') ne $source_root;

Repository has not been enabled to accept revision propchanges;
ask the administrator to create a pre-revprop-change hook

This hook is nothing else than an executable script located in repos/hooks/ that exits with 0 or 1 if defined conditions are not fulfilled. You can remove the file suffix tmpl from pre-revprop-change.tmpl¹ if the template already exists or you create it from the scratch.

For Unix systems the script looks like

#!/bin/sh
exit 0;

and for Windows it’s

@echo off
exit /B 0

I’ve defined a EDataType EPoint that uses the java class org.eclipse.draw2d.geometry.Point.

In the code I set the start and end point of the ElementView by the corresponding setter that I pass instances of the class Point ( and not EPoint! ).

ElementView view = factory.createElementView();
view.setStartPoint(new Point(20, 20));
view.setEndPoint(new Point(100, 100));

Saving the model produces the following file content:

...
<diagrams name="NewDiagram">
    <diagramView diagram="//@diagrams.0">
      <elementViews startPoint="Point(20, 20)" endPoint="Point(100, 100)"/>
    </diagramView>
  </diagrams>
...

The instances are serialized by the method toString() of the class Point which outputs Point(xx, yy) but these values lead the loading process fail while this message appears:

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'Point(20, 20)' is not legal. (file:/.../test1/model.pe, 7, 76)
18:28:12 zprototype.model.impl.ModelManagerImpl::load   Model could not be loaded (org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'Point(20, 20)' is not legal. (file:/.../test1/model.pe, 7, 76))
	at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.handleDemandLoadException(ResourceSetImpl.java:315)
	at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoadHelper(ResourceSetImpl.java:274)
	at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:397)
	at zprototype.model.impl.ModelManagerImpl.load(ModelManagerImpl.java:63)

I tried to replace the Point class by another one but it’s the same problem with that. Now my question is why the value is not legal? Does the deserializer not know how to create the objects from the string?

I often download enumerated PDF files. Before I’ve automated this job I downloaded the files by changing the URL manually in the browser. I could use an enumerated file downloader like this one¹ but I want to learn scripting so I do the same job using the shell.

What do we need? A loop of course. This increments the postfix number of the files. Then we also need a command which actually downloads the resources. For this I use wget. And here’s the result, a one line script:

for (( i=1; i<=14; i++)) do wget www.example.com/path_to_the_files/file$i.pdf; done

If you don’t script much you should take a look at the manual page of bash (or the shell you use). The website Linux Shell Scripting Tutorial is also a good place to look up things.

Maybe you have to download enumerated files too. Just copy the line, paste it in your shell and change the start and stop parameter of the counter and the resource of course

I think to use the shell everytime I want to download enumerated files will suck. So the next step is to write a firefox plugin ².

defaults read com.apple.Terminal

If you type this in your shell you get the settings set for your application, in my case for Terminal. I was interested in the entry “Default Window Settings”. The value of this key was Basic though I have explicity set it to Homebrew in the configuration panel.

defaults write com.apple.Terminal "Default Window Settings" Homebrew

This line affects the style permantly. Restart Terminal to read the new settings and enjoy the new style.

• Extend EditorPart
• Define a RootEditPart, GraphicalViewer and an EditDomain
• Create the model in createPartControl
• Set the viewer’s RootEditPart, add the EditDomain to the viewer and create its control
• Set the viewer’s EditPartFactory
• Set the viewer’s content (=model)
• Implement getAdapter to return the requested object by the framework

This very brief description doesn’t help one write a functional eclipse plugin but it may help one to keep in mind what to do.
