Get Variable Name as string
« on: May 05, 2020, 09:58:22 am »
Hello. I was trying to get the name of the variables used in QB64 as they appear in the source code. I tried using the stringify method from C++ but of course it gives me the C++ interpretation that QB64 does which gives it an entirely new name. Is there a way to get the name of the variable used in the QB64 source in a similar fashion as to how it is done in C++ using the stringify preprocessor? It would be quite an amazing thing if so.

Code: QB64: [Select]
  1. DECLARE LIBRARY "getvariablename"
  2.     FUNCTION GET_VARIABLE_NAME$ (variable AS STRING)
  3. PRINT GET_VARIABLE_NAME(test$)  

Output of code: (char*)(__STRING_TEST)->chr

I don't know if there is way, I'm just curious about your motivation. What do you intend to accomplish?

Also: For the final binary, the BASIC code never existed, so __STRING_TEST is as close as I think you'll get.

What I'm hoping to do is match MySQL column names to local variable names. For example:
Code: QB64: [Select]
  1. IF DB_RESULT(1,1) = GET_VARIABLE_NAME(customerId) THEN
  2. 'do stuff
This might help me to make my code more accurate in database queries. Perhaps. Maybe not. I do something similar in C# when using a dataset and accessing it like this:
string customerId = EdiCustomers["customerId"].ToString()
Doing so grabs the data at the column name customerId and assigns it to the local variable of the same name. I was thinking that if I at least had the ability to access the name of the local variable then I could do something along the same lines.

@Mark: Okay, now after reading this thread I understand the post you linked from here.

To me, reading the variables in the source code means opening the source file, and parsing out things like A$, x!,type variable names, etc. So not the values represented, but the actual variable names used. That's what I'm getting from this thread, but I'm not going to go in depth with how to do it, because my spidey sense tells me I may be barking up the wrong programing tree.

Exactly, Pete. I'm wanting to get the actual name as represented before compilation. Something that can get the value as how QB64 sees it in the IDE rather than during the compilation process when it gets converted to C++ code. I saw B+'s idea but it doesn't really do what I'm looking for. I suppose hard coding a variable with the name of another variable (what B+ showed) is a way of doing it.

To do that:

1) In your program, open the source code for BINARY or INPUT. BINARY read is a lot faster.

2) In your code, write a sub-routine that parses out all the variables and then eliminates the duplicates. That will leave you with an array filled with unique variables, to compare to your database.

Now writing the code to parse out variables is easy for strings that end in $, or numeric variables that end in %, !, etc. If you have types, DIM variables as strings, or don't use numeric identifiers like %,!, etc., that code gets a lot more complicated to write.

I made a rudimentary variable retrieving routine to help me keep up with the variable names I had in really large programs. It didn't do some of the more complicated stuff I mentioned, so I never published it. Without the more complicated parsing abilities, it just wouldn't be all purpose enough for everyone.

I'm out for a bit, but I'll return to this thread tonight. If it helps, I can dig up what I have, I think I know what computer I have it on, and if you could understand it, you could build on it, if needed.

Of course by posting what I did above, when I come back tonight there will be at least one post with a variable detection routine here, but hey, that's a good thing. I'm not the only genius here.... just the best looking one. :D

Well I can see how you can get a list of variable names and the task would be made easier with OPTION _EXPLICIT where you are forced to DIM everything, UDT's might be tricky.

I am curious how you will connect the variable names to ... what? after complied.

Half- followed this thread so forgive me but what about vwatch?
You're not done when it works, you're done when it's right.

Re: Get Variable Name as string
« Reply #10 on: May 06, 2020, 10:49:44 am »
@Pete, do you remember why you wanted a list of variable names?

I confess not understanding SpriggsySpriggs  (< opps mispelled sorry!) answer to Fellippe.

The only 2 apps I can think of for needing a list of variable names is color highlighting for bas editor or for an interpreter.

Does anyone else know of application?

It does sound like a Rosetta Code Challenge kind of thing.

Perhaps an AI might want to create a variable to it's own program.

Ah yes! An AI that modifies bas files, say to automatically improve code, we may be at edge of Code Fiction territory :)

Ah yes! An AI that modifies bas files, say to automatically improve code, we may be at edge of Code Fiction territory :)

Before I added our precompiler into QB64, I used external AI to improve code and add functionality.   (I still do, for some things...)

For example, I can write a program like this:


Code: [Select]
'#WB:ME
'#LICENSE:WTFPL
'#CD:DATE$
'#UD:DATE$

None of that means anything to QB64 itself -- it just reads it as comments -- but instead of using QB64.EXE to compile that program, I'll use QB64-Precomp.EXE.

QB64-Precomp will then read that and translate those lines as needed into a different BAS file. 

'WB:will generate a series of lines similar to:
Code: [Select]
Center, 10, "Written By"
Center, 11, "Steven McNeill"
Center, 12, "230 McNeil Hill RD, Pilot, VA"
Center, 13, "(smcneill@swva.net)"
Pause, 15
CLS

'LICENSE: will insert the appropriate license into my code, to display to the end user.

'CD: is the concept/creation date.  It replaces DATE$ with the current date when compiled the first time.

'UD: is the Updated Date, which remains and appends a series of current date/time when compiled.

By parsing those 4 little unique variable names from the code, it saves me a lot of repeative writing in my programs and improves readability/scrollability for the rest of the program which does whatever I'm trying to do with my code.

Re: Get Variable Name as string

@Pete, do you remember why you wanted a list of variable names?

I confess not understanding SpriggsySpiggs answer to Fellippe.

The only 2 apps I can think of for needing a list of variable names is color highlighting for bas editor or for an interpreter.

Does anyone else know of application?

It does sound like a Rosetta Code Challenge kind of thing.

I may have put the first program together as a response to someone asking for such a program at QBF, many years ago. The second one, I believe I used once or twice, myself. Why? Probably to get a better handle on the programs, to rename certain variables without duplicating a name already in use,  etc. While many programmers completely plan out their projects before they code it, I simply code as I go. That holds true for the small stuff as well as the largest apps I've made over the years.
