Context:
Hex now supports dbt's semantic layer. For example, you can use macros in the SQL cells. I have got the integration setup and verified my dbt macros work as expected when manually inputing parameters of the macro.
Problem:
How do I pass Hex input parameters into the macros? In dbt, the variables are in reference, so you don't need to bracket the inputs since the macro is bracketed. I believe the issue is that I need to quote the argument, otherwise dbt can't find the variable. There is no clear way to do this with hex. Anyone figure this out?
As an example:
my input parameters: exp_name.
I have a dbt macro: do_something(x).
When calling this in dbt like {{do_something('my_argument')}} the macro works. However, when I call it in hex with the input parameter like {{do_something(exp_name)}}, dbt compiles it as missing variables and I no result is returned.
Any help is greatly appreciated!
I tried manually quoting the variables with f-strings and setting these within the Jinja context but that did not work either.

In vue, is there a way to have a value span multiple lines in an .env file. Ex:
Instead of:
someValue=[{"someValue":"Here is a really really long piece which should be split into multiple lines"}]
I want to do something like:
someValue=`[{"someValue":"Here is a really
really long piece which
should be split into multiple lines"}]`
Doing the latter gives me a JSON parsing error if I try to do JSON.parse(someValue) in my code
I don't know if this will work, but I can't format a comment appropriately enough to get the point across so see if this will work:
someValue=[{"someValue":"Here is a really\
really long piece which\
should be split into multiple lines"}]
Where "\" should escape the newline similar to how you can write long bash commands while escaping the newline. I'm not certain the .env interpreter will support it though.
EDIT
Looks like this won't work. This syntax was actually proposed, but I don't think it was incorporated. See motdotla/dotenv#333 (which is what Vue uses to parse .env).
Like #zero298 said, this isn't possible. Likely you could delimit the entry with a character that wouldn't show up normally in the text (^ is a good candidate), then parse it within the application using string.replace('^', '\n');
I am using a VB to run .bat file and to pass arguments to it.
Right now I managed to run it and to send the arguments to it, but ran into a problem. My arguments might contain spaces inside. I was trying to use quotes, but it didn't seem to work as I expected. So what I am doing:
Running this code: System.Diagnostics.Process.Start("C:\Users\XXXXXXX\Desktop\New.bat", """"+data+"""")
where 'data' is the argument I am sending. For testing it contains the value:
Hel loo
Inside the .bat file I have a code, that opens notepad and writes the argument inside it. With this code I have managed to pass the argument as one with spaces, but the result is:
"Hel loo"
Any ideas how to get rid of the quotes on each side, while still passing the argument as one with spaces?
I cannot escape them or replace with another symbol. This solution needs to pass the argument as one with spaces inside. Is this possible? The program I am working with is not important.
EDIT
This is the content of the .bat file:
set directory_Rexe="C:\Users\XXXXXXX\Desktop\testBat.txt"
set var=%1
echo %var%>%directory_Rexe%
%directory_Rexe%
You have three options here:
Use %~1, which will strip the quotes.
Don't care about putting everything into argument 1 and quoting and use %* instead. You mentioned not wanting that, though.
Don't pass the string as an argument, but as an environment variable instead. This also helps a lot when you have a number of characters in it that need to be escaped.
All options require you to change the batch file, though.
I'd also question the need for a batch file when you have a perfectly capable programming language already at your fingertips. Writing text to a file should actually be easier from VB.
Context
I am thinking I can solve a problem with the proper creation of a *.bat file.
I am automating a process in a backup program called Acronis Backup and Recovery.
I am able to make a script (jScript) that creates all the syntax except for one part correctly.
In a normal command prompt the command I would run looks like this
acrocmd backup file --include="C:\documents\Gale_thesis.doc" "D:\Sandbox\!oDC!-IMG_0222.MOV" "C:\temp\magnifyReader" --loc="D:\backups" --arc="Backup1a"
The jScript I am creating can generate this with no problem and save as a *.bat file. This can works perfect if my file names are clean. By clean I mean no characters the batch files think are key words and commands.
Anytime I have a word like “copy” or a character like “!” in a file name it fails.
Question
So I am now wondering if loading variables from a text file would do the trick?
I am sure a lot of readers know that when load multiple file/folder paths at the command line you need to surround them with double quotes.
So I need this variable to have the correct syntax to be parsed by the batch file and work like the example when I type it directly at a command prompt.
I had tried to follow info about using for /f etc.
But the examples are not broad enough for me to understand, nobody seems to explain how to use these variables mixed in with other syntax.
I know a little about working with variable in a *.bat file. My jScript application can produce the text in any format a list, escaped, what ever is needed.
Thanks
I might suggest you to take a look at escaping characters
http://www.robvanderwoude.com/escapechars.php
in for loops !var! is used when delayedexpansion is enabled so you might need to escape it
I used the following code provided by Aacini to test the arguments that are being passed
#echo off
setlocal enabledelayedexpansion
set argCount=0
for %%x in (%*) do (
set /A argCount+=1
set "argVec[!argCount!]=%%~x"
)
echo Number of processed arguments: %argCount%
and since delayedexpansion is enabled I had to escape ! character
arg.bat --include="C:\documents\Gale_thesis.doc" "D:\Sandbox\^^^!oDC^^^!-IMG_0222.MOV" "C:\temp\magnifyReader" --loc="D:\backups" --arc="Backup1a"
Also about the triple escape quotes ^^^
the problem here is that we need to pass two special characters,
1st is the up arrow ^ and 2nd is the exclamation mark !
so the 2nd batch file (the one that reads our arguments) should get ^!
to escape ^ we use ^^ and to escape ! we use ^!
Thanks to Aacini for his code in HERE
I've been trying to write a simple script compiler for a custom language used by the Game Boy Advance's Z80 processor.
All I want it to do is look at a human-readable command, take it and its arguments and convert it into a hexadecimal value into a ROM file. That's it. Each command is a byte, and each may take a different number of arguments - arguments can be either 8, 16, or 32 bits and each command has a specific number of arguments that it takes.
All of this sort of code is handled by the game and converted into workable machine code within the game's memory, so I'm not writing a full-on assembly compiler if you will. The game automatically knows how many args a command has, what each command does, exactly how to execute it as it is, etc.
For instance, you have command 0x4E, which takes in one 8-bit argument and another 32-bit argument. In hex that would obviously be 4E XX YY YY YY YY. I want my compiler to read it from text as foo 0xXX 0xYYYYYYYY and directly write it into a file as the former.
My question is, how would I do that in VB.NET? I know it's probably a very simple answer, but I see a lot of different options to write it to a file--some work and most don't for me. Could you give me some sample code as to how I would do this?
Writing an assembly compiler as I understand it is not so simple. I recomed you to use one already written see: Software Development Tools for Z80 Family
If you are still interested in writing it here are instructions:
Write the text you want to translate to some file (or memory stream)
Read it line by line
Parse the line either splitting it to an array or with regular
expressions
Identify command and arguments (as far as I remember it some commands
does not have arguments)
Translate the command to Hex (with a collection or dictionary of
commands)
Write results to an array remembering the references for jump
addresses
When everything is translated resolve addresses and write them to
right places.
I think that the most tricky part is to deal with symbolic addressees.
If you are still interested write a first piece of code (or ask how to do it) and continue with next ones.
This sounds like an assembler, even if it for a 'custom language'.
Start by parsing the command lines. use string.split method to convert the string to an array of strings. the first element in the array is your foo, you can then look that up and output 4E, then convert the subsequent elements to bytes.
I have seen DEBUGLOG(x,...) syntax. It supports DEBUGLOG(x,...) or DEBUGLOG(x...).
If we alter dots like DEBUGLOG(x,..), it gives an error. Can anyone explain this?
Thanks in advance..........
This is a "variadic" macro, meaning it takes multiple arguments. It's the macro equivalent of a C variadic function like printf. The ... means "and any other arguments beyond here are OK too".
http://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html
When the macro is invoked, all the
tokens in its argument list after the
last named argument (this macro has
none), including any commas, become
the variable argument. This sequence
of tokens replaces the identifier
VA_ARGS in the macro body wherever it appears.
(I'm not certain why "x..." works without a comma. That's not a form you'd usually see.)
