Input text box is being ignored in the latest online website!

Go to lab.antlr.org and do the following:

• Start from a freshly opened browser. You can do it in different browsers, the result is the same.
• Select the "Java" grammar.
• Press "Run".
• The input is correct, but the parse tree is completely wrong, as though for some some stale input, rather than fetched directly from the control.

Go to http://134.209.209.215/ and repeat the steps. It works correctly. This is my website with my original code before the latest changes.

The input text box looks correct but the parser input is something else!

I traced it down to this code, which returns 1, but the code just ignores the result, trying to just continue.

Manually typing the pdfcrop command:

root@ubuntu-s-1vcpu-512mb-10gb-nyc1-01:/tmp/antlr-images# pdfcrop --hires temp.pdf
PDFCROP 1.40, 2020/06/06 - Copyright (c) 2002-2020 by Heiko Oberdiek, Oberdiek Package Support Group.
!!! Error: pdfTeX run failed with value 1!

The temp.ps file looks fine, and temp.pdf also looks correct. The result of the command creates a zero-lengthed "tmp-pdfcrop-NNNN.pdf" file.

I never quite understood why you call pdfcrop. That is why I removed the step because I don't think it's necessary. After removing the step, I just did "pdf2svg" of temp.pdf directly, and it produces fine svg's.

After it fails, the stale, left over temp.svg that was done by some--any--client is just returned. It should really nuke the file after sending the result back to the client.

hmm...works for me on C. let me try java. wow. weird. it's the crop? i did that to avoid padding to a full page I think.

oh. already have issue: https://github.com/antlr/antlr4-lab/issues/38

Just gotta add thread ID to filename.

Just pushed a fix. It appears to work. thanks, Ken!

Yes, that works a lot better!
