The versions are documented here: https://github.com/pnpm/spec/tree/master/lockfile

But I am not sure why you need this. We only support the two last major versions of pnpm. And including two versions of lockfile-types is not hard using aliases.

not sure why you need this

to write a pnpm lockfile parser for snyk/nodejs-lockfile-parser#111
i need the typescript types to generate a schema validator
(and to write the parser in typescript)

ideally the parser should support multiple lockfile versions
no need to support all versions, but a range from 5.0 would be nice

the alternative to maintaining multiple src/version/*.ts files in parallel:
updates and release @pnpm/lockfile-types for every lockfile-version
problem: to fix bugs in an old versions, we would need git branches

@pnpm/lockfile-types is used only by pnpm
and its a devDependency, so no need to optimize for bundle size

ok

Is this dead? Can I help in any way?

this has low priority for me, so practically its abandoned

if you need this, feel free to continue

my devloop was something like

• scrape pnpm lockfiles from github with test-versions/github-scrape-files/github-scrape-files.js
• from the lockfile types, build schema validators for all lockfile versions, and validate all lockfiles with test-versions/validate-lockfiles-pnpm.sh (obviously the absolute paths are not portable)
• when validation fails, fix the lockfile types, repeat

here are 150 MB of pnpm lockfiles: scrape-pnpm-lockfiles

there is some related work in nodejs-lockfile-parser/parse-pnpm-lockfiles
but to add pnpm support to nodejs-lockfile-parser, its probably simpler to use @pnpm/lockfile-walker as suggested in snyk/nodejs-lockfile-parser#111 (comment)
