Core (p5.js)

Modifying p5 Documentation

1. Generate a p5.min.js file containing changes via npm run grunt

2. Add the new p5.min.js file to the docs directory by using ./copyfiles.sh

3. Steps 1 & 2 can be done as one-liner: npm run grunt && ./copyfiles.sh

• install only the modules needed to run project
• run pip freeze to generate a requirements.txt file
  • list of all installed packages and their versions

Option 2 - via pip-compile

• install pip-tools

Using a new branch to create pull requests

Taken from slides from the "Getting Started with Open Source" talk at RC

1. Fork and clone
2. Create a new branch
   • git checkout -b branchName
   • or git switch -c branchName ([more info][0])
3. Do the fix
4. Commit the changes

void main ()

	gl_FragColor = vec4( vVertexColor, 1.0 );

Keeping a fork up to date

Attending the "Getting Started with Open Source" talk at RC today, inspired me to finally figure out how to keep forks up-to-date.

Preamble

• Always make your changes in a branch
  • this way, you can,
    • keep the main branch of the fork in sync with upstream
• ?

outputFile = ""

byts = []

with open( outputFile, 'wb' ) as file:

	file.write( bytes( byts ) )

Type exportvertices2csv in the Ruby Console.
Exports all Vertices is a Selection to a X,Y,Z 'CSV' file.
Edit sep="," if something other than a separating comma is desired e.g. ';'
Make sep="\t" if a TSV file is desired and change ext="csv" to ext="tsv".
It uses the current Model Units/accuracy with the approximate '~ ' and 
unit suffix [if any] removed; e.g. change Model Units to 'meters' 3dp to 
get exported csv in meters 1.234 - don't use 'fraction' 1' 2 1/2" formats,
