Simplifying tpl programs by putting functions in a seperate file.

[Carl Giles]

I would like to put many subroutines (functions) in a 'routines.tpl' file and load that file in at the beginning of my main .tpl source file so that I can do a lot with a file of 30 or so lines of code (because the thousands of lines of functions are hidden while I write.)

Could someone split up the example cds.tpl into cds.funcs.tpl carrying the functions, and load it into Cds.tpl which would just use the functions? I have tried the require keyword, and either I try it in a way where the file for the functions can't be found, or I get it to load in, but for some reason it doesn't find executable code there.

On this PC I have Linux Mint and Camotics 1.2.0.

Thanks,

Carl

You can use the require() function to load in other programs.  E.g. var routines = require('routines.tpl');.  You have to make your functions accessible by exporting them.  I recommend doing it like this:

var routines = {

  a: function () {

    routines.b();

  },

  b: function () {

    console.log('Hello World!');

  }

}

module.exports = routines;

Then you can do this:

var routines = require('routines.tpl');

routines.a();

I tried that.  The last two lines went into 'main.tpl'

The first 11 or so lines went into 'routines.tpl'

both files were in the ~/CNC/camotics directory.

I loaded 'main.tpl' into camotics, and it couldn't find 'routines.tpl'

I tried renaming 'routines.tpl' to routines.json'

and changed the line to:

var routines = require('routines.json');

but that didn't work.

I get the impression that javascript is very very sensitive to syntax.

Try require('./routines.json');

  I have found that if all the files are in the same directory, then the .tpl file can import the routines.tpl file if the ./ is prepended to the name:

require ('./routines.tpl');

as in your example, the subroutines must be separated by a comma, and not a semicolon.

Thanks.

Hi there,

I'm trying to do the exact same thing as recommended here. But when I compile it in CAMotics, I get the following error:

ERROR:Exception: ReferenceError: module is not defined

ERROR: at C:/code/CNC/Geom.tpl:57:1

Any ideas as to why it's not working on mine?

Thanks in advance,

Erica.

Oops, please ignore, I had added the library module to the camotiocs project, which generated that error. Once removed it worked as advertised.

Thanks,

Erica.
