ftrimify

See this blog post for more info on why ftrim() is cool.

Adds an item to the right-click menu of string parameters, as well as to the Gear menu of any node. ftrimify wraps channel references like ch() and chs() in ftrim(), to help round off excess precision in string parameters.

Quick Overview

It's common for string parameters to add a bunch of extra digits you don't want.

Say you have a FLIP object with a particle separation of 0.1. When referenced in a string parameter like:

`chs("/obj/dopnet1/flipsolver/particlesep")`

it will probably come out to something like

0.10000000000000001

We can help fix it using the HScript expression ftrim():

`ftrim(chs("/obj/dopnet1/flipsolver/particlesep"))`

Menu Items

ftrimify

Only string parameters will have this option added to their right-click menu. Select it to have all ch() and chs() channel references wrapped up in ftrim().

If a channel reference is already wrapped up in ftrim(), it will be skipped so that you can safely run it again if you update your node/parameter without adding a bunch of extra ftrim(ftrim(ftrim(ftrim(...))))s.

ftrimify All String Parameters

This is found in the Gear menu of any node. It runs ftrimify over each string parameter on the node.

Installation

Houdini Packages

1. Download the latest release here.

   • Optionally, you can clone this repo if you'd like instead.

2. Navigate to your houdini user preferences folder and into the packages directory (if the packages folder does not exist, create it).

   $HOUDINI_USER_PREF_DIR/packages
   

3. Copy the zip archive here and extact its contents.

4. Move (or copy) the ftrimify.json file to the parent directory $HOUDINI_USER_PREF_DIR/packages.

5. Launch Houdini

Manual Installation

If you prefer not to use Houdini packages for whatever reason, you can manually copy the files to any Houdini Location ($HSITE, $HOUDINI_USER_PREF_DIR) or anyhwere on your $HOUDINI_PATH.

• ParmMenu.xml and ParmGearMenu.xml should live at the root. ie. if you're moving these files into your user prefs folder, it should live right inside the houdini18.5 folder.
• Copy the module wranglegist.py to python2.7libs or python3.7libs (depending on your Houdini installation version)
