Breaking: Add support for default env & raw TeX post, unpack received zip 
this breaks the previous approach of writing the zip file to the file
system and letting the script unpack the files itself

Luzifer / tex-api

tex-api is a docker container being able to generate a PDF document from a LaTeX file and additional assets using a simple curl call.

Usage

  • Start the container at a trusted location:
    docker run -d -p 3000:3000 -v /data/tex-api:/storage luzifer/tex-api
  • Optionally provide a default env:
    docker run -d -p 3000:3000 -v /etc/tex-api/defaultenv:/default -e DEFAULT_ENV=/default luzifer/tex-api
  • Compile a ZIP file, send it to the API and get the result:
# zip -r letter.zip fonts main.tex sig.jpeg

# curl -sSL -H 'Accept: application/tar' --data-binary @letter.zip localhost:3000/job | tar -xvf -

main.pdf

# Using the default-env and exchanging a TeX file for a PDF
# curl -sSL -H 'Accept: application/pdf' --data-binary @main.tex -o main.pdf localhost:3000/job

What happened here is we packed all assets required for generating the letter into the ZIP archive, pushed it to the API, waited for it to build a TAR and extracted the resulting files from it.

API

POST  /job                  Create a new processing job (request body is expected
                            to be a ZIP file having at least one .tex file at the
                            root of the archive) and redirect to the /wait endpoint
                              Alternatively you can post a raw TeX file and let it
                            render through the default environment provided when
                            starting your container
GET   /job/{uuid}           Retrieve the status of the processing job
GET   /job/{uuid}/wait      Wait and redirect until the processing job is finished
                            or errored
GET   /job/{uuid}/download  Download the resulting archive (You may specify an
                            Accept header to select whether to receive a ZIP, a
                            TAR archive or just the raw PDF.)
