Repl Lint Failure happens in matrix-triangle-enum2str:

This happens even if I copy and use https://github.com/stdlib-js/stdlib/blob/develop/lib/node_modules/%40stdlib/blas/base/transpose-operation-enum2str/docs/repl.txt exact same with no modifications.

Node.js v20.9.0

REPL help lint errors.

[Pranavchiku]

This is done by copy pasting files from corresponding transpose-operation-* using cp -r transpose-operation-enum2str/* matrix-triangle-enum2str/ and then find and replace. I am not sure why we have lint error in repl.txt for enum2str.

[Pranavchiku]

The trouble is in line > var out = {{alias}}( {{alias:@stdlib/blas/base/matrix-triangle-str2enum}}( 'upper' ) ), with the following diff it works:

--- a/lib/node_modules/@stdlib/blas/base/matrix-triangle-enum2str/docs/repl.txt

@Pranavchiku This lint error is expected. The package is not yet in the REPL namespace. We can ignore for now.

LGTM. Thanks, @Pranavchiku!
