You see, these are the software problems I like most :-) Software that's working sometimes :-( Nevertheless I suppose I have to give it a try soon. Which will probably mean logging packets with timestamps at my home machine which wants to upload and doing something similar at the WebDAV receiving end at webdav.ethz.ch where I must do it probably at the WebDAV level because I can't just change the IP stack on this machine.

Text search + FTP

At least it should work :-) So if you like you can try it. OTOH after months of being occupied with other more pressing matters I started my WebDAV server on webdav.ethz.ch again. And I will have look into the problems there are. The difficult part is that I fear that these are not WebDAV but TCP/IP/HTTP problems. > > BTW is 'WebNavigator' usefull for local files ? > > It sounds like being intended for inet searching ? > > WebNavigator is an HTML 4.0 web browser.

Bad news :-( But I don't think it's possible for the (very small) Oberon community to provide a better browser. Even if it's perhaps not giving many academic laurels I think that an OS which hasn't at least some decent capabilities for browsing the Web doesn't have a great appeal to new people. So I can only beg ETH to invest some energy e.g. to integrate the good stuff from WebNavigator (Some support for frames and CSS) into the standard browser. A decent browser is basic stuff nowadays which is expected of an OS of any value. Or what about a WINE for Oberon ? I just installed it on my Debian today to see what it's capable of. > Anyway Google does support XMLRPC.

The file only has 512 bytes and half of them are junk. I assume that there are still problems somewhere in TCP/IP which are probably also the cause of the FTP problems discussed recently. AFAIK there was a major rewrite of the Aos TCP/IP and this wasn't simple. Even when upload from Aos worked also for files of more than e.g. 50K I had problems with uploading files of this size from NO. So is there any hope that NOs TCP/IP will be fixed to work with Aos (Assuming for now that it has a problem) ? Having finished some other things I problably will have a closer look at WebDAV again the next weeks. Cheers, Edgar

Oberoners, Please post me the output of: Watson.ShowDef FileDir.Enumerate My ver 2001 [ which is possibly out of date] shows:- DEFINITION FileDir; IMPORT OFS; TYPE FileName = OFS.FileName; EntryHandler = PROCEDURE (name: ARRAY OF CHAR; time, date, size: LONGINT; VAR continue: BOOLEAN); VAR PathChar: CHAR; (* Enumerate files matching the mask. proc is upcalled for every file. Iff detail is TRUE, the time, date and size parameters will be valid. Recursive calls to Enumerate are not allocated in proc. *) PROCEDURE Enumerate (mask: ARRAY OF CHAR; detail: BOOLEAN; proc: EntryHandler); END FileDir. --- In particular, I'm 'looking for' PROCEDURE EnumerateFile which I suspect, comes with the 'Win' version ? Thanks. == Chris Glur.

Of course that's > an "or" type search. It looks like you're wanting > to do "and" searches. Yes please ! Google blows my mind away: I need the press/print report[s] of municipal corruption exposed on TV last night [here is deep-dark africa]. By ANDing a few key-words I've got it/them. Obviously the print occured before the TV - google won't update from distant locations within hours ? What attracted me to [the existing] "Find" is that it uses "Find.Domain <file list>", so you can 'refine/restrict' the file search-space by existing tools. Eg. by SmartDir.Directory [which I suspect is not included in the distributions, but which I use daily, and should be included]. Running RX.Grep <file of list-of-files> \i <extentions/types to omit> trims out the fileTypes which are not to be searched. Eg. in a BIG SYS: partition, you can skip all: *.Obj, *.Bak, *.Scn.Fnt, ...etc. [which can't be moved out to their own partition] by building a file list, [for repeated use], by repeated applications of RX.Grep. BTW. v2.3.2 has a facility & panel to include a date range for the files to be searched [it's potentially problematic, since the date format required is not obvious]. I'm wondering why this was omitted from later versions ? > > Edgar who wrote:_ > > > The problem is that I have to find WebNavigator > > first.

But in a worse case one only knows something about the file contents. BTW is 'WebNavigator' usefull for local files ? It sounds like being intended for inet searching ? I don't want to spend half a day installing another package that doesn't do what I need. The collecting and moving of all files [copy & delete] to the appropriate partitions takes effort/time. Thanks. == Chris Glur.

Chris, cg> It looks as if it connected. Certainly. cg> Do you know/confirm that it 'echoes' fully and correct eg. by comparing with another client? Not shure what you mean. I suppose my next steps are to study the source modules and the relevant RFCs, turn on whatever debugging output I can find and try to understand the failure. Anyone know the current numbers for FTP RFCs? cg> Can you do some other inet-command after 'freeing yourself from the FTP loop'. Yes. FTP to Mac NetPresenz on my LAN and other network services are OK. Suggests that the problem is in the FTP protocol. cg> the developer of inet utilities tests it against his available facilities ... Pity that the RFCs are not simpler and more clear. Gutknecht, p. 107, _The School of Niklaus Wirth_, "...a few lines of formal text, in combination with expressive names, are worth more than a thousand pages of verbose and lengthy explanations."

Well as I've indicated, 'Find' already does multiple files, and it would be trivial for someone [ELSE ;-] to extend it to search for a set of strings [in any order] all contained in some of a set of files. I don't find the regular-expression facility usefull in this context. I've never used it with google. Nor do I know if google has decided it's worth offering. Recently is was VERY important for me to find a press article. I selected 5 key words, and google found it. So I love google and I want to evolve-refine my local file searching facilities towards what google has PROVEN to be of value.

The module is self-documented. Thanks, if/when I've got time I'll investigate deeper. Right now I need a cheap & quick solution, as does Edgar who wrote:_ > The problem is that I have to find WebNavigator first.
