Inserting filenames into html lines
Alfred Mansfield
Can someone help me with this problem?
I have a folder filled with 50 or so picture files (gif).
I want to write a batchfile which can be placed inside this folder and upon
excuting it, it would automatically generate a series of lines; shown below:
---------------------------
<a href="PICT~A.gif"><img src="PICT~A.gif" alt="1" width="100"
height="100"></a>
<a href="PICT~B.gif"><img src="PICT~B.gif" alt="1" width="100"
height="100"></a>
...
<a href="PICT~X.gif"><img src="PICT~X.gif" alt="1" width="100"
height="100"></a>
---------------------------
Where PICT~A is the filename of the "first" gif file and PICT~X is the
filename of the "last" gif file in the folder. It is not neccessary that
the gif files must be in some particular order (they are not named that way
anyway)
For those who understand html, you would see that this is actually a nice
picture gallery generator. It's simple but very useful.
I attempted it by doing this:
---------------------------
command/c FOR %%n in (1 2) DO prompt $la href="%1"$g$limg src="%1" alt="1"
width="100" height="100"$g$l/a$g $_ |FIND/v "prompt">_____
type _____|find "a href=">>index.html
---------------------------
This works but it is very troublesome as I have to pull each gif file at a
time onto the batchfile in order for it to generate that corresponding line
for that gif file.
I am looking for a way in which the batchfile automatically generates and
inserts the gif filenames into the PICT~ variables in the html lines above.
If possible, it would be better to use the dir/b command so that the full
filename wouldn't used. (In above example, the full filename is unavoidably
generated in dos, this looks cumbersome and is not necessary as the
index.html would be placed in the same directory as the gif files)
Any help or advice would be appreciated!
Thank you!

Also, if your interested in using Qbasic, here is an old batch you could
look at too. It don't do exactly what you want (displays all .gif files on a
single page), but you can possibly figure it out on your own.

BTW, I don't write code in this compact fashion any more. If you can't
figure it out to modify it, then pass it up because I'm not going into an
off topic 'How to use Qbasic' type of thread.

As it happens, I'm working on a related problem in another window at
this time. I'm using AWK scripts to read the files and replace
replacable parameters. Your problem is much simpler since you have
only one variable.
@echo off
DIR /b *.gif > }{.txt
echo {printf( "<a href=\"PICT~%%s\"><img src=\"PICT~%%s\" alt=\"1\"
width=\"100\" height=\"100\"></a>\n", $0, $0) } > }{.awk
gawk -f}{.awk }{.txt > out.txt
del }{.*
Where gawk is the appropriate version of the gawk interpreter for your
OS - see <http://gearbox.maem.umr.edu/~batch/multilingual.html> for
background information and downloading location (it's completely free
(a GNU port under the FSF's GPL)). Real lines are indented two spaces
- anything against the margin wrapped and is part of the line above.
When run against my c:\myfiles directory, it produced this output:
<a href="PICT~east.section.gif"><img src="PICT~east.section.gif"
alt="1" width="100" height="100"></a>
<a href="PICT~Schroedinger-cat-l.gif"><img
src="PICT~Schroedinger-cat-l.gif" alt="1" width="100"
height="100"></a>
<a href="PICT~ted_at_work.gif"><img src="PICT~ted_at_work.gif" alt="1"
width="100" height="100"></a>
<a href="PICT~west.section.gif"><img src="PICT~west.section.gif"
alt="1" width="100" height="100"></a>
If "PICT~" is part of the real file names, remove it from the printf()
string. To insert more instances of the file name, just insert "%%s"
where you want it and and another ", $0" to the printf() arguments.

Using my program COLS, via sig line 3, this would be a one-line job if
we had longer lines. As is, we need 2 lines (newsreader wraps the
first), and one for tidiness. #60 = < #62 = > #34 = "
DIR /b *.gif | COLS #60 'a * 'href= #34 1- #62 #60 'img * 'src= #34
1- #34 * 'alt= #34 '1 #34 * 'width= #34 '100 #34 > xxx
COLS <xxx 1- * 'height= #34 '100 #34 #62 #60 '/a #62 > yyy.htm
DEL xxx
COLS.PAS contains instructions.
Another way would be with MiniTrue, from <URL: http://www.pagesz.net/~mi
nitrue/>, or presumably SED - you need an editor that can recognise text
(here a whole line) and repeat it at will. As above, you just have the
tiresome matter of representing all those potent characters. The basic
job could be
DIR *.gif /b | MTR -x+ -no - "^(.*)\r$" = "xx \1 yy \1 zz\r"
and you could use later passes to expand xx yy zz ...
SED is more standard, but I'm not familiar with it.

You can loop through the .GIF files with a FOR loop, and use a
recursive call to the batch so that for each file name you append
the formatted output to the file. With an initial one-off
recursive call to execute the whole thing with stdout redirected
it should be pretty fast (100 files take about 3 seconds here).

Just wondering, what program did you use to make the com file?
It's very direct.

It is a normal assembler program (see listing below) which
is converted to an ascii only format with the following batch:
::----------------------------------------------------------------------
rem - save the lines below as CONVERT.BAT
rem - write a COM program and assemble it with ORG=0x178 (PROG.COM)
rem (you must not use the standard ORG=0x100 for this com program)
rem - enter: CONVERT PROG.COM PROG.BAT
rem - the BATCH file PROG.BAT contains an encoded form of PROG.COM

Is there/can you make a simple user-prompting exectable similar to "bat.com"
in your example which can be created in a batchfile.
This com/exe would simply pause the batchfile and prompt the user to enter a
string. It would then set this string as a variable.
It would work just like ASKENV.exe (if you have ever heard of it).
The problem with askenv is that I can't "insert" it into the batchfile just
like how bat.com was inserted.
This is useful because then batchfiles can be distributed without the user
having to install/copy extra msdos executables onto their hard disk.
Also, it doesn't require the user to input information in the batchfile
using the traditional method where a msdos window has to be opened and the
command had to be typed in manually followed by substituting %n variables.
Thanks for your help!

If you do not want raw binary in a script - and raw binary is
susceptible to un-noticed damage if the script is mis-edited,
then see whether my NQYR does what you need. Fetch via sig line 3.
{ NQYR EnvNam aaa bbb ccc
will write "aaa bbb ccc ? ", will read a line, and do the equivalent of
SET UpperCase(EnvNam)=<line read>
One character is ignored after EnvNam; otherwise, spaces and tabs count }
So NQYR fodder What's for lunch, Mum
might set FODDER to Roast Beef and Yorkshire Pudding

ECHO in dos can also be assembled this way (as with the myinput.com)?

Sorry, was a wrap around. Should be:
echo XP,;P_,EP0Ex0Ez0Em3Em-ZBP(Eiu![j@_YQ2M@53#@CI~.8'uxCISZ[SC5.bM!C>ech.com
ech.com does not append a <CR><LF> so your input starts after
Enter your name: and not in the next line.

After studying this batchfile over and over again I still get quite
confused!
What does "%=%" do?
Thanks!
PS. It is very fast!!
laura fairhead
It doesn't really do anything. In general %var% always gets replaced with
the contents of the variable named 'var'. There are no special /magic
variable names. So %=% will just get replaced with what is in the variable
named '='. The idea is that since you can't actually legally define a variable
with that name it will always evaluate to nothing at all. So it's really
just the same as a blank line when it comes down to it, and a blank line
would have been fine here. I just use that so that it is clear a blank
line should be there that's all. Since ECHO is ON at that point the
PROMPT gets printed, and this is why you couldn't just use a comment;
REM **** this line is just a place-holder ****
(because that would print the PROMPT and the REM ...... )
What bits of the batch don't you understand in particular?
The main thing going on is just the recursion mechanism on line2;
IF !%2==!. %3
It checks that parameter #2 is a period, and if it is then the
command in parameter #3 is executed. This means that any call to
the program like;
PROGRAM parameter1 . COMMAND
Gets to that line, and after variables are substituted (DOS always
substitutes all the variables before it does anything else) you
would get;
IF !.==!. COMMAND
'COMMAND' is always just 'GOTO:LABEL', so it will jump into the
program at the point ':LABEL'.
The first time this is done is on line 3 (when the program is
initially run from the command line);
%COMSPEC%/C %0 . . GOTO:MAIN>index.html
It just re-runs the program but the new run will jump in at ':MAIN'
(thus avoiding an infinite loop). All it is doing here is redirecting
output of the program to the file 'index.html'.
It is as if you were running some batch that produced output on the
screen, if you wanted that to go to a file instead you would use;
%COMSPEC%/C PROGRAM >file
Because %0 is the batch programs name all that is happening is
the program is doing this by itself and saves you typing.
Everything that happens after that goes to the 'index.html' file
instead of the screen.
After that it is doing the loop bit, because you want to do something
for each *.GIF file. You can't do more than one command in a FOR
loop so for each *.GIF file it issues a (returning) CALL;
CALL %0 %%_ . GOTO:GIF
That calls the program with the parameters;
%1 = GIF filename
%2 = .
%3 = GOTO:GIF
So when you get to line 2 and variables %2 and %3 are replaced you get;
IF !.==!. GOTO:GIF
The period in parameter 2 triggers the line to execute the command
and that is a GOTO:GIF. So it goes straight to the bit for outputting
your formatted HTML lines;
:GIF
PROMPT $LA HREF="%1"$G$LIMG SRC="%1" ALT=1 WIDTH=100 HEIGHT=100$G$L/A$G
ECHO ON
%=%
@ECHO OFF
:OUT
The PROMPT is set, just like in your original program. Turning ECHO ON
and then having that blank line means that one PROMPT gets output,
but of course because the output of the program is redirected now to
the file 'index.html' it gets added to that file instead of the screen.
I hope that clarifies it some for you. If there is still anything particular
you don't quite understand about it and want me to explain, then just
shout and I'll do my best....
