MAML cli tool. mx pretty-prints, queries, and edits MAML files.

npm i -g mx

Or run without installing:

npx mx data.maml

mx [file] [code...]

Pipe input or pass a file:

cat data.maml | mx
mx data.maml

Drill into data with dot notation:

.prop            access property
.prop.nested     nested access
.[0]             array index
.items[2].name   mixed access
.[]              iterate over array
.users[].name    map field over array

mx data.maml .users[0].name
cat data.maml | mx .config.server.port

Iterate over an array with []. The results are collected back into an array, so the output stays valid MAML:

mx data.maml '.users[].name'

Assign a MAML value to any path:

mx data.maml '.config.port = 8080'
mx data.maml '.users[0].roles = ["admin", "dev"]'

Edits print to stdout. Add save to write back to the file:

mx data.maml '.config.port = 8080' save
