ZSH and related

brew install zsh # only in linux sub-systems. Mac comes with ZSH installed.

To use zsh ability to use plugins to bring in features and also be aware of performance, antidote, a framework is used to install plugins.

brew install antidote

All plugins necessary go inside a text file and that file is bundled to a shell script. To install the .zsh_plugins.txt(use stow zsh to get in the right directory),

echo -n 'source /path/to/antidote.zsh' >> ~/.zshrc
echo -n 'antidote load' >> ~/.zshrc #loads whenever `zsh_plugins.txt` changes.

To update antidote, use antidote update.

Latex Installation

2025 update(takes 1-2hours totally. Use profile to save time)

(For quick install using the texlive.profile file. ./install-tl -profile texlive.profile)

  • Before upgrading to 2025 version, check previous version present inside home directory ~/texlive/{year}
  • Instructions for upgrade are given here - https://www.tug.org/texlive/upgrade.html (upgrade seems little technical. Didn’t proceed.)
  • Instructions for fresh install are given here - https://www.tug.org/texlive/quickinstall.html (perl install-tl -gui). Version 74223.
  • Goto this link — https://www.tug.org/texlive/acquire-netinstall.html, download unx-tar.gz file(ca. 5 mb).
  • change install folder prefix to home directory to avoid permissions.
  • change installation root to /Users/dross/texlive/2025(Choose prefix /Users/dross/, leave rest as it is and click OK). Go back again to see that the path is correct.(will create 2025 on its own). Will show some 9GB big files to install. No need for those.
  • Click advanced. (use the installation save profile option to use for next upgrade).
    • Leave texmf-local localtion as it is. It is for custom local files not to be overwritten by Tex live upgrade.
    • In ‘platforms’, make sure only mac is selected.
    • ‘Selections’ is the most important.
      • Need to change ‘Schema’ to only needed packages. Click ‘Change’, choose ‘custom schema’.
      • In ’N.of Collections’, click ‘customise’. Select ‘None’ in languages and select only English.
        • In ‘other collections’ - select ‘None’ and choose only needed. (I saved texlive.profile). Use that for later.
        • In short, languages- English and German, all latex, luatex, xetex, basic fonts and packages. about 725MB.
    • In Options, deselect everything. No need for docs or source tree. Use google or LLM. Also no need for symlinks. Put PATH, MANPATH and INFOPATH in .zshenv.
  • Save profile or click install. I think source as CTAN is automatically selected. Install takes around 20 mins to complete depending on the server.

export PATH=/usr/dross/texlive/2025/bin/universal-darwin:$PATH export MANPATH=/usr/dross/texlive/2025/texmf-dist/doc/man:$MANPATH export INFOPATH=usr/dross/texlive/2025/texmf-dist/doc/info:$INFOPATH
