Allow for configuring the CLI command used to invoke GDAL ogr2ogr about ogr2ogr HOT 6 CLOSED

Thanks very much!

from ogr2ogr.

Actually I have just tested this, and the command is not set this way

from ogr2ogr.

I'd be open to PR that allows you to switch the base command from the default.

from ogr2ogr.

I've added some code that as far as I can tell will work. (I'm sure that it allows for switching the base command).

However, I'm not able to get the examples to run -, related to this thread: #26

If I replace this statement:

let s = cp.spawn('ogr2ogr', logCommand(args), commandOptions)

With this statment (i.e. provide a command that I know exists on the $PATH of the invoking user):

let s = cp.spawn('docker run -v /tmp/:/tmp --rm osgeo/gdal:alpine-small-latest ogr2ogr', logCommand(args), commandOptions)

Running the examples I get the ENOENT error (the docker command appears not to be findable). If I replace cp.spawn with cp.exec then I get an error from the GDAL ogr2ogr client:

let s = cp.exec('docker run -v /tmp/:/tmp --rm osgeo/gdal:alpine-small-latest ogr2ogr', logCommand(args), commandOptions)

FAILURE: no target datasource provided

I think that the spawn command is not working as expected. I'm using Node.js 14.15 on WSL2 Ubuntu 20.04

from ogr2ogr.

I've adjusted the API like this:

// examples/docker.js
const ogr2ogr = require('../')

ogr2ogr('../test/samples/sample.shp.zip')
  .command('docker run -v /tmp/:/tmp --rm osgeo/gdal:alpine-small-latest ogr2ogr') // <= This is the addition
  .exec(function (er, data) {
    if (er) {
      console.log('er', er)
    } else {
      console.log('data', data)
    }
  })

Release in v2.1.0
