Re: [O] Difference between eval and export
I tried to make an example that does not need a lot of input data but without success. never mind, it works if I run the code on a single cpu, or if I run it on a linux machine.

[O] Difference between eval and export
hi all! I am wondering what the difference between the eval of a source block and the export of a buffer is in terms of the process in which the code is evaluated. Is the org-export call starting a new process? Is there a way to specify environment variables for the export process? thanks in advance for any information! best, jo
Re: [O] Difference between eval and export
thanks Grant for this information. I was just wondering, because it seemed to me that some environment variables (from the shell) are present in the, while they some (LC_ALL) are not present in the export process. In my case, the export call fails with an error message, while there is no problem if I evaluate source block per source block from the buffer. At present I am therefore looking for a way to specify environment variables in the export process, but I have no idea how to do that...

When you evaluate a source block, it executes in the processed defined by your configuration. Then the results of that evaluation are stored according to your configuration. For example store the results in an example block. Exporting is the conversion for the org file content into and file format. During that process, you can configure whether or not you want evaluation of source blocks to occur during that process.
