Can toml use variables?

[weichangdong]

dir=/tmp/
dir1={dir}dir1
dir2={dir}dir2

can toml reach this effect?

It can't, and that was a deliberate design choice. Any logic, complicated or not, is best handled by the consumer of the TOML file. TOML doesn't handle that logic.

So in your case, you can configure thedir and its subdirectories in TOML, and then have your program read the TOML and compute the subdirectory paths.

# Here's an example. 
dir = '/tmp/'
subdir1 = "dir1"
subdir2 = "dir2"

You can also include comments in the TOML file so that the configuration entries make intuitive sense.

Hope that helps.

But let's say we had a lot of information and a certain value appears a lot, wouldn't it be more readable to define it at the top of the file and then substitute in that name rather than repeat the value every single time? It would also make it easier to change all the values at once by only changing the variable instead of needing to go through each time that value is referenced and changing it there.

@Moosems Just as recently as last week, I said back in a different closed issue that you ought to propose the simple substitution idea that you had, with details that address previously raised concerns, as a new issue. Will you do that, so we can approach it fresh?

@pradyunsg Any chance we can start locking closed issues, so that the spamming will stop?
