       wasm-merge - manual page for wasm-merge 120

DESCRIPTION

       ================================================================================ wasm-merge INFILE1 NAME1
       INFILE2 NAME2 [..]

       Merge wasm files into one.

       For example,

              wasm-merge foo.wasm foo bar.wasm bar -o merged.wasm

       will  read  foo.wasm and bar.wasm, with names 'foo' and 'bar' respectively, so if the second imports from
       'foo', we will see that as an import from the first module after the merge. The  merged  output  will  be
       written to merged.wasm.

       Note that filenames and modules names are interleaved (which is hopefully less confusing).

       Input source maps can be specified by adding an -ism option right after the module name:

              wasm-merge foo.wasm foo -ism foo.wasm.map ...
