Package: arxiv-latex-cleaner
arxiv_latex_cleanerThis tool allows you to easily clean the LaTeX code of your paper to submit to
arXiv. From a folder containing all your code, e.g./path/to/latex/, it
creates a new folder/path/to/latex_arXiv/, that is ready to ZIP and upload to
arXiv.Example call:arxiv_latex_cleaner/path/to/latex--resize_images--im_size500--images_allowlist='{"images/im.png":2000}'Or simply from a config filearxiv_latex_cleaner/path/to/latex--configcleaner_config.yamlInstallation:pipinstallarxiv-latex-cleaner:exclamation: arxiv_latex_cleaner is only compatible with Python >=3.9 :exclamation:If using MacOS, you can install usingHomebrew:brewinstallarxiv_latex_cleanerAlternatively, you can download the source code:gitclonehttps://github.com/google-research/arxiv-latex-cleanercdarxiv-latex-cleaner/
python-marxiv_latex_cleaner--helpAnd install as a command-line program directly from the source code:pythonsetup.pyinstallMain features:Privacy-orientedRemoves all auxiliary files (.aux,.log,.out, etc.).Removes all comments from your code (yes, those are visible on arXiv and you
do not want them to be). These also include\begin{comment}\end{comment},\iffalse\fi, and\if0\fienvironments.Optionally removes user-defined commands entered withcommands_to_delete(such as\todo{}that you redefine as the empty string at the end).Optionally allows you to define custom regex replacement rules through acleaner_config.yamlfile.Size-orientedThere is a 50MB limit on arXiv submissions, so to make it fit:Removes all unused.texfiles (those that are not in the root and not
included in any other.texfile).Removes all unused images that take up space (those that are not actually
included in any used.texfile).Optionally resizes all images toim_sizepixels, to reduce the size of the
submission. You can allowlist some images to skip the global size usingimages_allowlist.Optionally compresses.pdffiles using ghostscript (Linux and Mac only).
You can allowlist some PDFs to skip the global size usingimages_allowlist.TikZ picture source code concealmentTo prevent the upload of tikzpicture source code or raw simulation data, this
feature:Replaces the tikzpicture environment\begin{tikzpicture} ... \end{tikzpicture}with the respective\includegraphics{EXTERNAL_TIKZ_FOLDER/picture_name.pdf}.Requires externally compiled TikZ pictures as.pdffiles in folderEXTERNAL_TIKZ_FOLDER. See section 53 in thePGF/TikZ manualon TikZ picture
externalization.Only replaces environments with preceding\tikzsetnextfilename{picture_name}command (as in\tikzsetnextfilename{picture_name}\begin{tikzpicture} ... \end{tikzpicture}) where the externalizedpicture_name.pdffilename
matchespicture_name.More sophisticated pattern replacement based on regex group capturesSometimes it is useful to work with a set of custom LaTeX commands when writing
a paper. To get rid of them upon arXiv submission, one can simply revert them to
plain LaTeX with a regular expression insertion.{"pattern":'(?:\\figcomp{\s*)(?P<first>.*?)\s*}\s*{\s*(?P<second>.*?)\s*}\s*{\s*(?P<third>.*?)\s*}',"insertion":'\parbox[c]{{{second}\linewidth}}{{\includegraphics[width={third}\linewidth]{{figures/{first}}}}}',"description":"Replacefigcomp"}The pattern above will find all\figcomp{path}{w1}{w2}commands and replace
them with\parbox[c]{w1\linewidth}{\includegraphics[width=w2\linewidth]{figures/path}}.
Note that the insertion template is filled with thenamed groups capturesfrom the pattern. Note that the replacement is processedbeforeall\includegraphicscommands are processed and corresponding file paths are
copied, making sure all figure files are copied to the cleaned version. See alsocleaner_config.yamlfor details on how to specify the
patterns.Usage:usage: arxiv_latex_cleaner@v1.0.4  [-h] [--resize_images] [--im_size IM_SIZE]

Clean the LaTeX code of your paper to submit to arXiv. Check the README for
more information on the use.

positional arguments:
  input_folder          Input folder containing the LaTeX code.

optional arguments:
  -h, --help            show this help message and exit
  --resize_images       Resize images.
  --im_size IM_SIZE     Size of the output images (in pixels, longest side).
                        Fine tune this to get as close to 10MB as possible.
  --compress_pdf        Compress PDF images using ghostscript (Linux and Mac
                        only).
  --pdf_im_resolution PDF_IM_RESOLUTION
                        Resolution (in dpi) to which the tool resamples the
                        PDF images.
  --images_allowlist IMAGES_ALLOWLIST
                        Images (and PDFs) that won't be resized to the default
                        resolution,but the one provided here. Value is pixel
                        for images, and dpi forPDFs, as in --im_size and
                        --pdf_im_resolution, respectively. Format is a
                        dictionary as: '{"path/to/im.jpg": 1000}'
  --keep_bib            Avoid deleting the *.bib files.
  --commands_to_delete COMMANDS_TO_DELETE [COMMANDS_TO_DELETE ...]
                        LaTeX commands that will be deleted. Useful for e.g.
                        user-defined \todo commands. For example, to delete
                        all occurrences of \todo1{} and \todo2{}, run the tool
                        with `--commands_to_delete todo1 todo2`.Please note
                        that the positional argument `input_folder` cannot
                        come immediately after `commands_to_delete`, as the
                        parser does not have any way to know if it's another
                        command to delete.
  --commands_only_to_delete COMMANDS_ONLY_TO_DELETE [COMMANDS_ONLY_TO_DELETE ...]
                        LaTeX commands that will be deleted but the text 
                        wrapped in the commands will be retained. Useful for
                        commands that change text formats and colors, which
                        you may want to remove but keep the text within. Usages
                        are exactly the same as commands_to_delete. Note that if
                        the commands listed here duplicate that after
                        commands_to_delete, the default action will be retaining
                        the wrapped text.
  --environments_to_delete ENVIRONMENTS_TO_DELETE [ENVIRONMENTS_TO_DELETE ...]
                        LaTeX environments that will be deleted. Useful for e.g. 
                        user-defined comment environments. For example, to 
                        delete all occurrences of \begin{note} ... \end{note},
                        run the tool with `--environments_to_delete note`. 
                        Please note that the positional argument `input_folder`
                        cannot come immediately after
                        `environments_to_delete`, as the parser does not have
                        any way to know if it's another environment to delete.
  --use_external_tikz USE_EXTERNAL_TIKZ
                        Folder (relative to input folder) containing
                        externalized tikz figures in PDF format.
  --svg_inkscape [SVG_INKSCAPE]
                        Include PDF files generated by Inkscape via the
                        `\includesvg` command from the `svg` package. This is
                        done by replacing the `\includesvg` calls with
                        `\includeinkscape` calls pointing to the generated
                        `.pdf_tex` files. By default, these files and the
                        generated PDFs are located under `./svg-inkscape`
                        (relative to the input folder), but a different path
                        (relative to the input folder) can be provided in case a
                        different `inkscapepath` was set when loading the `svg`
                        package.
  --config CONFIG       Read settings from `.yaml` config file. If command
                        line arguments are provided additionally, the config
                        file parameters are updated with the command line
                        parameters.
  --verbose             Enable detailed output.Testing:python-munittestarxiv_latex_cleaner.tests.arxiv_latex_cleaner_testNoteThis is not an officially supported Google product.
