Rev as Linux Shell Script
I'm sorry this is so long winded. I'm hoping it will help you understand my motivation... I am a necessity programer. I don't sell my programs, I program as a systems analyst to achieve results for my employer. I have developed fairly complex solutions in FileMaker and I can program in VB, Lua and I've even written a few C utilities (Text manipulation). I've written with PHP and Perl for web. And, as part of my job, I have to create reports from a legacy Cobol system using ODBC and Linux shell scripting. The problem is, I really don't know any one of these programming languages fluently :) When I switch between them (sometimes within the same day), I'm always having to get out a book and refresh my memory about certain syntax. Sure, I can remember most of the basics of program flow (If, then, else) between each one, but even then I sometimes type it wrong and have to go back and edit after it gets an error. SO, I thought I would try finding a language I can can call the one programming language I'll ever need. Along comes Rev (a couple of years ago for me) and I really felt like it would be a good candidate. I can program for Mac, Win, Web, Linux, Mobile devices... you guys know all that. However, a CONSIDERABLE amount of my programming is in Unix Shell script. We have a legacy accounting system running on SCO Openserver (We are changing over to Linux in 2011). I have a full EDI interface to one of our suppliers written in bash shell script AND I NEED it to be a shell type process in order for it to work for me. (nightly cron, headless computer, etc.) SO!!! The 'last' feature of Rev/LiveCode I need to be able to address is the ability to run LIKE a Linux shell script. I've read how to get the runtime working as a CGI and played around enough that I 'can' (seemingly) make it work from a shell with the #!revolution -ui declaration on the first line. However, when I get to some of the higher level features (FTP, ODBC, etc) I start getting errors. I was researching how to possibly resolve these issues (need libraries, etc) when I found that Rev 3.5 is the last version to support the ability to run as a CGI. Now, my questions... 1) Am I dreaming? Should I just move to Perl or something else and forget about Rev as a shell language? 2) I know LiveCode 4.5 can't do the CGI. Would it work for a shell script (some UI/Graphical features obviously not available) 3) If so, can someone point me to some documentation on how to set it up correctly. 4) My first test was to try FTPing a file (needed for EDI) and I get errors when it can't locate libURLftpUploadFile. Where is this library and where should I put it on the Linux box? 5) I've got an Enterprise License. Is this in violation of my license in any way?

Re: Rev as Linux Shell Script
If you stick to the 3.5 engine or switch to RevServer but want to do some net stuff not enabled by libURL, you can always shell() to cURL and be happy. Yes. However, I'm still having to work with 'non-rev' syntax (learning how cURL works). As it turns out, I already know most of it (bash'ing for so long), but that knowledge of how to use cURL or shell out to any other Unix shell command (awk, sed, etc.) really won't translate over to Rev if I want to use it as my primary development tool. For example, if I want to FTP a file from a LiveCode project developed for use on Windows, then I would be better off using libURL. (Yes, I know cURL could be installed on Win, but I'm wanting to simplify things) So, I've got to not only work with all the Unix tools while developing at the 'shell' level, I've also got to learn all the LiveCode ways of doing the same task. That is what I am doing, I was just hoping to to use Rev at the shell level (since most of my work is done there) in order to get more proficient with the Rev/LiveCode syntax. Kill two birds with one stone! So, the short answer is: No, Rev will not work well as a shell scripting language 'out of the box' I've used PHP to do 'shell utilities', I sure wish Rev could act similar. How nice would it be to just have one language/syntax for the bulk of your code.

Re: Rev as Linux Shell Script
Thank you so much. I will try this and let you know how it works out... Bill On Oct 28, 2010, at 3:03 PM, J.

You can insert libURL (or any other script) into the message path so that commands to the library will work with your CGI script. It takes a little bit of set up. First, in the View menu in the IDE, choose to show LiveCode UI Elements in lists. Then open the Application Browser and all the IDE stacks will appear. Scroll to the revLibrary stack in the left-hand list, expand it, click on its single card, and in the right side panel find the button revLibURL'. Right-click to edit its script, then copy it. Paste the script into the stack script of a new mainstack (for this way of doing it, it has to be the stack script.) Save the stack as revLibURL or similar. Upload the stack to your CGI folder on the server and set its permissions to 755. In your CGI script, put this near the beginning after the on startup line: start using stack revLibURL That will make the libURL script available to your CGI. After that you should be able to use libURL handlers as you do in the IDE. (In theory; haven't actually tried it. But that's how you create pseudo-includes.) The libURL library is updated frequently, so you'll have to repeat this process every time a new version of LiveCode is released if you want to stay current. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
RE: Windows 7 - any experiences?
I liked Windows 7 a lot. Much snappier than Windows Vista. Lots of updated drivers. A smarter UAC. I would probably use it except for two problems: 1) I prefer the Vista/XP task bar. And 2) there is no upgrade path from RC1 to the shipping version of Windows 7; you will have to do a clean install when it ships. Granted, I'm running it virtualized on my Mac, but my XP Pro virtuallized seems to me to run considerably faster than W7. I havent' compared it to Vista (skipped Vista alltogether) Windows 7 Hmm Seven... LOL Same Exact Vista Except Number? ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

RE: WorkGroup Manager
This is a little obscure, but I have a client who is using Apple's WorkGroup Manager who is claiming that they (admin) set the permissions of my [Revolution] application to read/write. Then, when the user logs in they don't have permissions to run the application. They claim this is not an issue with any other application they have. Dan, Shouldn't that be read/execute? They don't need to write to it - as you can't write to the rev application - as I found out this week :() Bill ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
RE: Best Practices Question
andre wrote: I use globals when I need sharing the data all across multiple scripts, stacks and the like and the data must be forgotten between runs. So, I use it for wide spread temporary data but these days I use only one global and that global is an array where I can put anything I want and still keep the global clutter low. Hmm, that's a good idea. That would certianly unclutter the top of some scripts! And I use customprops with data that needs remembering or are multiple line. If I need to store the data I am using, I will use a custom property or if I am fiddling with some constant or some data that will be used by my software as opposed from data that is inputed from keyboard or other data sources, then I will use a custom property. Common uses for me is storing templates and pieces of messages to be assembled later and presented to the user. I also store binary chunks in custom properties when needed. For example, storing curl.exe inside a custom property and pipeing it out case the windows user does not have curl installed and I need it. This is one area I am having issues. I'm new enough to Rev that I didn't realize fields on my Preferece Page (DB IP Address, DB Name, etc.) wouldn't be remembered between sessions when I make a Standalone! Can I take what the user enters in the fields for their Preferences (database's IP Address, DB Name, etc.) and then assign them to a Custom Property before they exit the standalone. Will that keep the data? OR, do I have to store that in a prefs text file and just parse it at runtime? What do others do?

Best Practices Question
Can someone point me to a Best Practices or good itermediate tutorial on programming in Rev. I've been able to do quite a bit and can use the dictionary to learn how to use the language, but I'm having trouble understanding how most people use Globals, Custom Properties, etc. I've read pro and cons on using globals. I've tried to write functions and pass params around to avoid them (which I think is best), but then there are times a global seems to be a better idea... OR would a Custom Property be better? I just don't know how others would do it. I've looked through a lot of examples and it seems it is all over the board! I know it isn't written in stone (and really a personal preference), but has someone put together a Best Practices document? We really need a Rev for Dummies book!

RE: Best Practices Question
Devin, Great stuff. Very helpful. If nothing else to confirm I'm not as lost as I feel sometimes. I find I do 90% or more of what you listed. I guess just from experience with other languages! Declare your local variables and enable the variable checking by default option. It will help prevent typos and cut down your debugging time. Variable Checking is one of the first things I found and turned on. I really like C because of its structure, but for the life of me I just can't think that way and get anything done in C. I'm very familiar with VB (I wrote our in-house EDI transaction processing from scratch in VB... Yikes!) and the first line of any of my projects in VB is Option Explicit. However, Variable Checking by default throws a stick in the spokes when you download other peoples work and accidentally hit the compile button when viewing their code LOL! (OK, OK, just don't hit save!!!) There! That's probably more than you bargained for. And I'm sure others will chime in with more advice. We all have plenty of that, for free. :-) I'm still reading the links you sent and Yes, this is a great group. Thanks to all!

I think Rev would be easier to learn if I had NO experience programming. I really like it, but I must admit, some of the approaches taken are too easy. I can't figure it out because it is right in front of me! Not to start a flame war, but it is sort of like Mac and Windows. I got my first Mac in 1984 and started thinking the Mac way early on. Then I got a job programming on Windows (hated it). Now, I use Windows every day and have migrated to a different way of doing things (The MS Way!) My wife uses our Mac at home and I have always had a Win machine. This last year, I bought ME a new iMac 24 (got her one too) for Chrstmas. I find I sometimes make things way to hard when I have to re-learn the way a Mac does something. I forgot how just plain sensible most things are on Mac. I guess Rev is sort of like that.

Launching .rev files on WinXP
OK, I guess I need the long weekend more than I realized... I have 3.5.0 build 870 on my WinXP Pro computer. When I double click on a .rev file, it luanches the Rev IDE, but it doesn't load the file. I must go to FileOpen and select the file. Then it will open. I right clicked on the .rev file and said Open with to see if it might correct the problem, but I don't even have the Revolution.exe file as an option. I browsed to the .exe and selected it, but it still won't show up in the list of available programs to open up the file... Anyone else seen this?

RE: Launching .rev files on WinXP
1) Open Windows Explorer 2) Select Tools Folder Options from the pulldown menu 3) Click on the File Types tab 4) hilite the REV Extension (typing REV will locate the line) 5) Click the 'Advanced' button 6) Select the 'Open' action and click the 'Edit...' button Now... In the 'Application used to perform action:' field, browse to the rev folder for which version of RunRev you want launched for ALL .rev files. The result of editing this, should look like this: C:\Program Files\Revolution Studio\3.5.0-gm-2\Revolution.exe %1 The %1 parameter is the file that is being selected to open by you. Mark, Yes, that worked great. Thank you. The weird part is, the Advanced button didn't show up at first. The button was actually Restore. There was a note that said the .rev files would be using the application for .rav and I could click restore to set it back to the default .rev Man, I have no idea how that happened.

RE: Other stacks opening besides the one selected
I will correct myself about files loading automatically, I was thinking of lower down in the folder hierarchy. Nonetheless, common sense would seem to indicate that storing data files in the Program Files directory would seem a Bad Idea. A agree. Not to mention the problems Vista has with users writing files in the Program Files folder. Will it really be in the Program Files directory? Or will it be vertualized? Or will you simply be denied access? Depends on lots of variables and how Vista is setup... The Program Files folder is for Program Files, not data. Most other Windows programs will put you in [My]Documents by default.
