Files

OK, I'm grabbing a list of all files in a directory and popping them in a variable. I'm then going through each file and replacing some text in each one.

Now, I only want to do the above process on text files. Is there a way to *just* get all the files with a '.txt' extension?

Currently, I'm doing this:

Code: Select all

  put URL ("file:" & rWords) into kWords

Which just grabs everything.

You need to use the defaultfolder, together with the files for this:

Code: Select all

On mouseUp
  answer folder "a Folder"
  if it = "" or the result <> "" then
    exit mouseUp
  end if
  set the defaultfolder to it
  set the itemdelimiter to "."
  repeat for each file rWords in the files
    if item -1 of rWords = "txt" then
      put URL ("file:" & rWords) into kWords
      -- do stuff here with kWords
    end if
  end repeat
end mouseUp

Fabulous.... I've got another question now...

Seems to me that it would be simpler to put all the names
into an array then delete the array elements which contain
the string ".txt" and process the rest.

One could also:
...
put the files into tFiles
filter tFiles with "*.txt"
## Now tFiles will contain only TXT files

...

I'm a believer in concise code so thanks for this
one Klaus.

As you might guess I'm just starting with Rev and
keep thinking of the "good old days" when
programming languages came with a dozen books
of info.

Even then the common complaint was that the info.
covered one topic without giving an example of doing
a project from start to finish.

What would you suggest is the best/quickest way
to find what I'm looking for? The info. seems to
be there but the problem is where is "there".

Have a copy of the 2.1.2 PDF but the information is
spread around in a haphazard way and it takes so
long to search all 3193 pages!

Hi bjb007,

I would suggest that you

1. work through all stack you canfind here:
http://support.runrev.com/scriptingconferences/

2. Then grab all stacks that you can get from "Revonline" and other websites that offer unprotected downloads, and dive into all their scripts.

At least for me this is the best way to learn Rev!

Best

I find the best way to learn a programming language is to have something to do. I've had RunRev on my laptop for over a year, but it's only now I really had a use for it.

I looked at existing scripts to get most of what I needed and then asked questions here, eventually the structure, syntax and design of RunRev begins to bed in.

Now looking to enhance the programs I've written which in itself will teach me even more.

Thanks for your replies Klaus and Andycal.

Perhaps my "problem" is that I became very
proficient with dBase and FoxPro in the '80s so
usually go looking for something that was
available in those languages.

So knowing what I want to do I need to find a
way of doing it and going through stacks takes
a lot of time and then I mightn't find what I want.

Can you or anyone else tell my why the Rev help file
isn't at all like the one in the videos? If I had that
I'd be away....

Wonder if anyone has thought of having a Wiki-style
Rev resource where users could add ideas and code
which would be easily searchable. A lot of the sites
I've visited which claim to be devoted to Rev have
very little of use to me and a lot of them have that
"abandoned" look.

LiveCode Forums.
