Scalar 1,932 began at Microsoft as a tool for the Windows and Office monorepos and has shipped with Git 1,932 since 2.38 as a separate scalar command. It applies this section's techniques in one step: scalar clone makes a blobless partial clone with a cone-mode sparse checkout, puts the working tree under src/, and sets several dozen performance options:
scalar clone --no-maintenance file://$PWD/../server/booknest.git ../big
ls -C ../big/src
git -C ../big/src config list --local | grep -E "fsmonitor|untracked|filter|index.v|graph"
scalar delete ../bigInitialized empty Git repository in /home/dev/v5-ch2/big/src/.git/ ... README.md docker-compose.yml package-lock.json server.js app.js eslint.config.js package.json core.untrackedcache=true core.fsmonitor=true remote.origin.partialclonefilter=blob:none commitgraph.changedpaths=true commitgraph.generationversion=1 fetch.writecommitgraph=false index.version=4 /home/dev/v5-ch2/big/src
core.fsmonitor=true starts Git's file-system monitor daemon, which Git 2.55 brought to Linux: git status asks it what changed instead of scanning every file. The untracked cache remembers directories without new files, and index version 4 compresses path names. Without --no-maintenance, Scalar also registers the enlistment for git maintenance's maintenance; scalar delete unregisters it, prints its path and removes it. Scalar suits repositories with hundreds of thousands of files; for BookNest a plain clone is best.
