mojoshelf:

pixi shelf add snappy-mojo

pixi shelf comes with mojoshelf: install it first.

plain pixi:

pixi init app -c https://conda.modular.com/max -c conda-forge && cd app
sed -i.bak 's/^\[workspace\]/[workspace]\npreview = ["pixi-build"]/' pixi.toml
pixi add "mojo-compiler==1.2.0"
# Without mojoshelf: the tin as a git dependency at its published commit.
# Transitive dependencies may be wrong: pixi takes the tin's own git deps as
# pinned in its pixi.toml, which may not match what other tins pin, and then
# fails with "duplicate records". mojoshelf picks revisions that agree.
pixi add snappy-mojo --git https://github.com/magmalake/snappy.mojo --rev b8172ed0a4ef13911cc225d46e26676a5b8f1ccd

No mojoshelf needed. If pixi reports duplicate records, the mojoshelf tab picks revisions that agree.
