Purpose

The file styles/ElectricalEngineering.isy provides electrical engineering circuits components for IPE. The additional customization file ipelets/customize.lua enables the following additional shortcuts:

• Shift+S to add symbols
• Alt+Ctrl+I to add splines

German instructions on installing and using Ipe can be found here.

Installation

Linux

Styles file

Copy the styles file styles/ElectricalEngineering.isy into the user directory ~/.ipe/styles/ (styles may have have to be created first). You can either do these steps manually or use this script:

mkdir -p ~/.ipe/styles
cd ~/.ipe/styles
rm ElectricalEngineering.isy
wget https://github.com/christiankral/ElectricalEngineering.isy/raw/master/styles/ElectricalEngineering.isy

Customization file

Copy the customization file ipelets/customize.lua into the user directory ~/.ipe/ipelets/ (ipelets may have have to be created first). You have to change

prefs.styles = { "/path/to/ElectricalEngineering.isy" }

to the absolute path

prefs.styles = { "/home/user/.ipe/styles/ElectricalEngineering.isy" }

(where user is your user name). You can either do these steps manually or use this script:

# Download, copy and configure customize.lua
mkdir -p ~/.ipe/ipelets/
cd ~/.ipe/ipelets/
rm customize.lua
wget https://github.com/christiankral/ElectricalEngineering.isy/raw/master/ipelets/customize.lua
sed -i 's@~@'"$HOME"'@g' customize.lua

Windows

We are assuming that IPE is installed in C:\bin\Ipe; but it may be installed somewhere else.

Styles file

Copy the styles file styles/ElectricalEngineering.isy into the Windows directory C:\bin\Ipe\styles\ (styles may have have to be created first)

Customization file

Copy the customization file ipelets/customize.lua into the user directory C:\bin\Ipe\ipelets\ (ipelets may have have to be created first). You have to change

prefs.styles = { "/path/to/ElectricalEngineering.isy" }

to (note the double backslashes)

prefs.styles = { "C:\\bin\\Ipe\\styles\\ElectricalEngineering.isy" }

Version handling

Ipe files created with ElectricalEngineering versions before and after v0.5.0 are not compatible.

Older files can be updated under Linux using the script Resources/update1.sh. This script inserts an updated version of ElectricalEngineering.isy into an ipe file and fixes compatibility issues caused be new component names. If you encounter any conversion problems, please file an issue.

This script converts one or more Ipe file to ElectricalEngineering version v1.X.X.

Conversion Examples

• update1.sh File.ipe updates File.ipe by inserting ~/.ipe/styles/ElectricalEngineering.isy
• update1.sh "*.ipe" updates all files *.ipe by inserting ~/.ipe/styles/ElectricalEngineering.isy
• update1.sh "*.ipe" /work/ElectricalEngineering.isy updates all files *.ipe by inserting /work/ElectricalEngineering.isy
