Quotes are automatically added when using the home directory

[xicheng412]

when I use the following code

const home="~"
$`ls ${home}`

Expected Behavior

shell run the command > ls ~

Actual Behavior

home directory changed > ls $'~'

reason

In the file src/index.mjs

function quote(arg) {
  if (/^[a-z0-9/_.-]+$/i.test(arg) || arg === '') {
    return arg
  }
....
}

the filter dose not contain ~.

How should I write it when I need to use a path that includes the home directory?

Well, this is little bit more complicated question.

First, please, read https://github.com/google/zx/blob/main/docs/quotes.md.

Right now, no substitution is made for ~ tilda. We can take a look on how it’s implemented right now in bash and do the same.

Problem with allowing tilda: how are you going to do this:

echo “~”

I appreciate your support very much. Actually I am not using the Home directory locally, I'm running script like:

ssh server1 "sh ~/cmd.sh"

I have some different servers with different username. ssh config contains the infomation about username. os.homedir() can not use in remote server.

I solved the problem with this method.

const {stdout:pwdRes} = await $`ssh ${serverName} "pwd"`
const remoteHome = pwdRes.split('\n')[0]
console.log(path.join(remoteHome,remote.base,remote.file))

While default login path is home dirctory, I saved the path as remoteHome, then use path.join to get full path.

The following is very important and useful information in the documentation:

globbing and ~

As everything passed through ${...} will be escaped, you can't use ~ or glob
syntax.

In order for this to work the zx provides
globby package.

For instead of this:

let files = '~/dev/**/*.md' // wrong
await $`ls ${files}`

Use glob function and os package:

let files = await glob(os.homedir() + '/dev/**/*.md')
await $`ls ${files}`
