is there a way to implement so called "record" and "field" data structure?

an idea is something like below but with a wrong batch grammar

Why don't you make an example of what your output file should look like? We are all trying to guess.

I guess you are looking for a .txt file (you can call it a .csv file if you want):

Code: Select all

field1;field2;field3:field4;field5;
field1;field2;field3:field4;field5;
field1;field2;field3:field4;field5;
field1;field2;field3:field4;field5;
field1;field2;field3:field4;field5;

You can even have a 'key' in your file (I have lots of experience with indexed files (and COBOL) when I was still using OpenVMS):

Code: Select all

KKKKK;field1;field2;field3:field4;field5;
KKKKK;field1;field2;field3:field4;field5;
KKKKK;field1;field2;field3:field4;field5;
KKKKK;field1;field2;field3:field4;field5;
KKKKK;field1;field2;field3:field4;field5;

In the example above you can use FINDSTR /B /C:"KKKKK;---------YOUR KEY------------;" to find specific records. And when you get them you can process them with a FOR /F loop. (KKKKK can be avoided of course but you could add more info into a file with another special letters (LLLLL, MMMMM, NNNNN...) if 'key' values are the same. There are cases where I store my data in a .cmd itself (and I find this data with FINDSTR /B /C:"KKKKK..." - so I only have to copy one file instead of two (or more).

More info you provide better answers you will get (see viewtopic.php?f=3&t=11287 again).

The below is my own implementation of this type of data structure, and includes a usage case example.

Edit: added some more remarks, modified delimiters / field seperators to cope with records containg field values that match fieldIDs within the record.

>More info you provide better answers you will ..

this was what i did currently, i am using it but...
IF "%var1%"=="1" SET "D1=dostips" &SET "D2=%abc@zyx.com%" &SET D3=aaaa
IF "%var1%"=="2" SET "D1=ztree" &SET "D2=%zzz@poi.com%" &SET D3=cccc
IF "%var1%"=="3" SET "D1=youtube" &SET "D2=%txx@123.com%" &SET D3=vvvv

if i decided to alphabetically REORDER or INSERT new lines from above, it would be like below then i would have to change var1's number, and the display lines in ECHO command would also have to be changed
IF "%var1%"=="1" SET "D1=dostips" &SET "D2=%abc@zyx.com%" &SET D3=aaaa
IF "%var1%"=="4" SET "D1=linkbar" &SET "D2=%hhh@ggg.com%" &SET D3=kkkk
IF "%var1l%"=="3" SET "D1=youtube" &SET "D2=%txx@123.com%" &SET D3=vvvv
IF "%var1%"=="2" SET "D1=ztree" &SET "D2=%zzz@poi.com%" &SET D3=cccc

so i wanted to try a new data format that wouldnt need ordering and inserting and deleting as below
FOR %%V IN (
"AA 31" D1 11
"BB 21" "D2 2" 22
"CC 53" D3 33
) DO (

all i need is copy cut paste to REORDER, INSERT and etc
FOR %%V IN (
"BB 21" "D2 2" 22
"AA 31" D1 11
"zz" "D3 2" 44
"CC 53" D3 33

if i choose var1==2 as "record" number 2 then it brings out field21=%%U field22==%%V field23==%%W, was the idea i wanted to try
************************
FOR %%V IN ( .... ) DO ( output is everything one straight down
"AA 31"
D1
"BB 21"
"D2 2"

but if the idea FOR %%V %%U IN ( .... ) DO ( goes the way, the output will be
"AA 31" D1
"BB 21" "D2 2"
***********************************

for T3rry
it may take a while for me to try, my batch command and operator abilities are low
thanks for the time being

[nnnmmm]

>You can even have a 'key' in your file
not this way at the moment. keys automatically take whatever the order in which data are wrttien
example)
SetLocal EnableExtensions EnableDelayedExpansion
SET CC=0
FOR %%U IN (
A
E
D
B
) DO (
SET /A CC=!CC!+1
ECHO !CC! "%%~U"
)

!CC! number is the key, probably the simplest or the toughest if i have to deal with data strings with "!" in them
if %var%==27 echo get 27th !CC!'s %%U

and later....choice /C:1234567890abcdefghijklmnopqrstuvwxyz /N /M "Input:"
IF "%ErrorLevel%"=="33" echo get 33th !CC!'s %%U

if there is no easy way,
i will try to use // or ## as a divider to get this way
SET SS=%%U
SET S1=!SS:~3,10!
SET S2=!SS:~13,24!
SET S3=!SS:~30,44!


//"A 1" //"BB" //"2123"
//"AAAAA 1" //"BB BBBB" //"2123 DDDD"

Edit: I've amended the example to include a method of extracting all fieldIDs to generate menu options, to avoid having to
manually update such menus whenever you add a fieldID to the record.
Edit 2: Refactored + Remarks refined.
The previous @lookup and @extractFieldIDs macro's have been built into the Menu macro.

[miskox]

I am not sure if I understand exactly what are you trying to do. But anyway:

For example: you enter your data (for example with SET /P) and then write it to the output file. This means that you have your input file. Now you enter your 'key' (line number in this input file). Now depends what are you trying to do:

If you want to remove this line (record) from the file you just use FINDSTR /B /V /C:"%key%;" your_file.txt. (key is the line number. Notice the ';' (let's say ';' is the field delimiter in your file)). With this ';' at the end you make sure FINDSTR only finds one record you want (1; for the first record and not records that have 1; in it (1; or 11;)). See FINDSTR's help (/B searches for a string at the beginning of a file, /V outputs lines that do not match (so your line is not in the new output file), /C makes sure your search is not treated as regex).

You can easily use SORT to sort this file (in this case I would recommend that you make sure keys are all of the same length). If you want to change 'key' values (so there are no 'missing lines') then you have to reread the file and create a new one.

Hope this helps.

C:\ZTREE\NirCMDC.exe BEEP 500 100
ECHO "%L3%" | CLIP

:END

i kind of got it and the code is kind of working for the only choice number 1, because i can not display these two below due to my lacking in batch commands
"xtree\b@z.com\bbb\"
"ztree\c@z.com\ccc\"

you could understand my code in about 20 seconds and you could know what i wanted to do
if my code all worked, all i need would just feed more of this kind of data inside the FOR () DO
"xtree\b@z.com\bbb\"
"ztree\c@z.com\ccc\"
"nirsoft\d@z.com\fff"

hope to help me.

ps

i think there is a bug in FOR /? that says

for /f "eol=; tokens=1,2,3 delims=\" %i in () do @echo %i %j %k
it didnt even work with a SINGLE % and NOT %%

Take a look at this.

@ECHO OFF
SetLocal EnableExtensions EnableDelayedExpansion
SET CC=0
for /f "tokens=1,2,3 delims=\" %%A in (m:\aa1.txt) do (
SET /A CC=!CC!+1
set "L1=%%A"
set "L2=%%B"
set "L3=%%C"
ECHO !CC!. !L1!
)
rem ------------------------------------
ECHO.
SET /P "VAR=Input: "

for /f "tokens=1,2,3 delims=\" %%A in (m:\aa1.txt) do ( this one worked, what a wonderful day for me!
all i need was just to supply an extra file aa1.txt that had
dosti\a@z.com\aaa\
xtree\b@z.com\bbb\
ztree\c@z.com\ccc\

in FOR /?..... for /f "options" %var in (file-SET) do () was also misleading
it was NOT a SET that diverted me to list the data inside the FOR () DO (), it was just a SINGLE file name.

thanks for all your efforts to help me
but i couldnt understand high power batch commands and operators
to me they were like a modern car that has no extra spaces under hood that i could stick my hands into for repairing and modding
