Terminal colors with plugin-run-script

[brianjacobs-natgeo]

I have a script that's doing some handlebar preprocessing that lints and compiles html to snowpack. I'm using plugin-run-script to watch html files. Before snowpack, I was using this script with chalk to color my terminal output. This is a piece of logging in my watch script

const msg = chalk.red('[') + chalk.yellow('L ' + message.line) + chalk.red(':') + chalk.yellow('C' + message.col) + chalk.red(']') + ' ' + chalk.yellow(message.message);
console.log(msg);

In the plugin-run-script log area, the colors that used to show outside of snowpack are gone.

Any thoughts here?

Alternatively, i would love not to have to use the plugin system and instead use a snowpack JS api. i.e.: I invoke something like const snowpackServer = snowpack.dev() and then i could just dip into the snowpack logger directly. THen call snowpackServer.logger(chalk.green("message")) from elsewhere. Basically I'm just trying to show nice non-snowpack console messages without it being repainted by how snowpack logs things--the plugin system is the only way I've found that to be possible.

So looks like a problem with chalk as a child process. Replacing chalk with colors or using normal ansi codes seems to work but gulp further uses chalk internally. Using --color flag to force colors fixes the issue. e.g:

"plugins": [
            [
                "@snowpack/plugin-run-script",
                {
                    "cmd": "",
                    "watch": "gulp watch --color"
                }
            ]
        ]

Another avenue might be to set environment variable FORCE_COLOR=1 somewhere. More clues here https://github.com/chalk/supports-color#info
