Houdini VEX Editor v1.0.8

alt tag

I am proud to present the latest tool I made for Houdini. This time an editor for VEX code! It is a good alternative to builtin editor in Houdini. During development user feedback and requests have been a decisive factor. And yes you can now change font size! This is only one small feature. Following text will present a full list of features and abilities it will give you. I am open for new ideas and suggestions for expanding it further. Feedback, suggestions ideas and feature requests can be sent to my email: [email protected].

What can VEX Editor do

edit VEX code and parameters of any node
edit code sections of VEX operator
edit *.h or *.vfl files
connect editor with source, quick saving of code by Ctrl+Enter
auto creation of parameters, used in code when saving
removal of unused and renamed parameters
auto change type parameter when saving
VEX syntax highlighting
quick change of font size (Ctrl + Mouse Scroll)
color themes mimicking Houdini themes as well as custom, editor specific themes
quick access to help cards by pressing Shift+F1
autocompletion for VEX functions, data types, keywords. List of functions generated automatically for current build of Houdini
auto complete functions and variables of the current code, as well as of the connected through #include files
auto complete context
- nodes existing parameters for the function ch, chv, chi, etc.
- standard attributes, switched on after the @
- the existing attributes of the current geometry SOP Content (node Wrangle)
- *Global variables are switched on after the symbol $
input and output parameters of inline node, switched on after the $ symbol in the node inline
directives and their parameters are switched on after the # symbol
included files from path HOUDINI_VEX_PATH, switched on after entering the "#include" and the opening quotation marks, " ' or <
templates as well as templates for quick insertion of the Tab key after the keyword
regular backup in case of the crash of Houdini
preservation of open tabs in a hip file and automatic recovery when reopening
display an error message in the editor’s interface
auto indentation and indentation control with Tab and Shift + Tab

*Attention!

NOT recommended that you use global variables in the VEX code.

It's possible to read and write global variables directly (for example, P and Cd in the SOP context). However, we strongly recommend you do not use global variables directly. Houdini does not guarantee the order in which VOPs generate their code, so assigning values to globals can give unpredictable results. Instead, you should explicitly wire from the globals node into this node. Unlike the Point SOP, this does not use local variables. Further, all backtick expressions and $ F variables will be evaluated at frame 1, not the current time. Use Frame, Time, or TimeInc instead.

New in v1.0.6

You can show or hide tool bar

Added "Save as..." action in Tabs menu

Added "Open settings folder" action in Editor menu

Bugfix

Renamed settings folder

Number bar now have static width

Some fixes for linux systems

New in v1.0.7

Added help window to show quick help for function in cursor focus (Menu -> Editor -> Help Window)

Now context help (Shift + F1) worked if cursor not only above function name but also inside arguments

Added "Find and Replace" window. Use Ctrl+F to open

Bugfix

Interface Description

Buttons main panel


	Quick connection nodes. This button is looking for attributes and the snippet code, or section VflCode. If one of the items found, immediately opens the editor with reference to the found item. It can also act as a rapid transition to the tab with the parameters of the selected node
	Selecting from the list
	Opening a file
	Create a blank tabs with the ability to bind it to a parameter or saving a file
	Saving code tied to a parameter or a file. The same as the keys Ctrl + Enter
	Reload the source code of the bound parameter or file or in the current tab
	Highlights node connected to the current tab (if the tab is attached to the parameter node)
	Open the folder with the file (if the tab is attached to the file)

Ctrl + Enter - save the current code
Shift + F1 - open help about the function, which is currently under the cursor
Tab - to add a space from the current position or to highlight the code
Tab - after the keyword template is added to the current cursor position
Shift + Tab - to remove the indentation of the current line or selected lines
Alt + Q - comment out or uncomment the current line or selected lines
Ctrl + D - duplication of the line or a selected code
Ctrl + Z - Cancel
Ctrl + Y - Redo
Ctrl + C - Copy
Ctrl + X - Cut
Ctrl + V - Paste
Ctrl + Mouse Scroll - change the font size of the current tab
Alt + Mouse Scroll - Editor to scroll left \ right

When you open the widget autocomplete

Arrow Up / Arrow Down - move the focus on completer, select a row
Enter - to use the current line completer. By default, the first
Esc - close completer if it is not in focus
Any other key - to go back to the editor and continue typing

Installation

First, download and unzip the package pw_VEX_Editor his path PATH, PYTHONPATH or standard directory Houdini for Python scripts. For example $ HFS / Houdini / scripts / python. Next, you need only to load the script as PythonPanel. Also, you definitely need a module hqt. Download last version!

Houdini 13

If you are using version 13, you have no way to open the editor as a PythonPanel. Then you can try to use module hqt. I myself am at this version of Houdini did not tested. Read the documentation of hqt, try to run.

Houdini 14

Since this is a common VEX Editor PythonPanel you can adjust its opening alone. Either use a ready file python_panels / vexeditor.pypanel. In addition, the 14th version of Houdini you can use the module hqt to quickly create and open PythonPanel. About how to do this, see the documentation for the module hqt.

Houdini 15

In Houdini version 15 implemented an excellent opportunity to add specific PythonPanel as a new Houdini panel. Therefore, you can simply add the supplied script python_panels / vexeditor.pypanel to python_panels folder in your HOUDINI_PATH and include VEX Editor to the list of panels. Hqt module is still required.

Linux

Installation is no different. Tests were conducted on Ubuntu, Kubuntu, and Debian.

Using

To start writing code in the VEX Editor is enough to make three simple steps:

VEX Editor Open in new tab (see the installation instructions)
Select node wrangle, inline, snippet or VEX operator
Press btn1 to quickly create tabs. The required parameter will be found automatically.

Everything is ready to edit code! Save the result at any time using a hotkey Ctrl + Enter or the button on the panel.

Known Issues

The main problems associated with the implementation of Qt on a particular system. In view of such problems on MacOS, some interface elements do not display correctly. Their defeat is not yet possible. Therefore, for the performance of the script on the Mac I can not vouch. In the future, I will try to fix it.

Houdini 15 at this time was released recently and has a number of problems both with conventional tools and with the implementation of Qt. This is in particular caused the error in the module and replacement hqt widget auto complete list of the standard. All this will be corrected as the stabilization of Houdini.

Another problem is the custom VEX operators. To create a parameter on the custom operator you need to specify the arguments of main function. For example like this:

sop myoperator (int value) {
...
}

Once you add the new arguments and click Apply in the Type Properties, Houdini recreates parameters of your operator. Unfortunately, the same does not occur if you replace the operator code programmatically, and in the current implementation of HOM or HScript I have not found a way to do this programmatically. I am hoping to solve this issue soon. Temporary solution to the problem - open the Type Properties window and click Accept.

I really hope that this tool is useful to you in your work. Ideas for new chips and error messages as usual to send [email protected].
