Support for installing on other Linux distro?

Hello,

I see that this provide installer for Ubuntu, but would it be possible to make an installer for other non apt, non deb distro?
I also would like to create eSIM package as Flatpak.
https://www.flatpak.org/
and distribute it in Flathub.
https://flathub.org/home

Flatpak can install on any distro that support them, which most distro does. KiCAD is already in Flathub.
https://flathub.org/apps/details/org.kicad.KiCad

I am trying to understand install-esim.sh at the moment.
Would you interest for eSIM as Flatpak?

Resolve remaining pep8 issues

Issue Details-

• Travis CI added for continuous integration
• Clean the flake8 errors uptill now, to enable easier integration

Logging feature implemented

Issue Details-

• Logging feature to improve the ability to debug for incoming programmers
• Currently print() statements used everywhere
• Rather can use logging library from python to display more data beside the print statements

Ideas-

• Logging to a file, so that incase of errors, can ask the user to mail the log files, along with other necessary files as netlist to debug application.

eSim splash screen hides the workspace dialoge box on launch

On Ubuntu 15.04 operating system upon launching eSim, the splash screen hides the dialogue box which prompts the user to choose the workspace location. Unless the workspace location is not chosen eSim wont be launched. User unaware of the dialogue box in the background might have to wait endlessly for eSim to launch. However upon a mouse click the splash screen quits itself and the workspace dialogue box becomes visible .

The splash screen should either disappear after a time out period or the the workspace dialogue box should be above the splash screen.

Add feature to rename projects

Add feature to rename projects, and also their respective files, in the selected folder.

Python plotting issue

Issue Details-

• Whenever python plotting called, there are instances where the plot_data_i.txt and plot_data_v.txt are not generated or display previous values.
• The problem appears to be, at the time.sleep() call after ngspice is called to generate the plot_data files. Since ngspice can take more than the specified time
• Refer function- open_ngspice(self) at src/frontEnd/Application.py file

Edit: Add relevant tags such as bug

Ngspice is CASE insensitive

Description

Ngspice is CASE insensitive.

However, if we need path of a directory to be passed in netlist, say "/home/sumanto/Desktop" gets converted to"/home/sumanto/desktop".

A temporary fix has been decided to add a '$' before the CAPITAL letters to identify them.

Expected Behavior

Ngspice should be CASE sensitive for paths, string values, etc.

Version and OS

• eSim 2.2
• OS: Windows 10, 64 bit, Ubuntu 20.04, 64 bit

Rewriting docstrings according to sphinx documentation

Description

Not all functions in the eSim code is written in accordance with the Writing docstrings section in the sphinx documentation
The docstrings in the functions have to be rewritten according to the documentation.

Automate the packaging of eSim

Description

Currently the packaging in eSim is done manually.

However, it is difficult to package everything and follow the steps as new features get added on.

It also takes huge amount of time and the developer also needs to go through a proper checklist.

We need to automate the packaging of eSim to solve the above problems.

Steps to Reproduce

Automate the packaging of eSim.

Expected Behavior

A script/code should package the eSim automatically and the developer must have to do minor changes to the script whenever there are change in modules.

Version and OS

• eSim-2.2 onwards
• OS: Windows (whichever supported by eSim)

Wrong default components are shown from previous_vals files

While extracting previous components and data from previous_vals only the first letter and first number are matched.
Ex. q12, is matched against q14 as well as q12 , q13, q1....

Please fix to check the whole letter and number.

Using Volare to automate SKY130 installation

Description

SKY130 PDK gets copied to a location manually in the installer of eSim:
https://github.com/FOSSEE/eSim/blob/installers/Ubuntu/install-eSim-sky130.sh

Expected Behavior

It may be automated using the following Python Package:
https://pypi.org/project/volare/

Adding support for multiple simulations

Description

eSim currently does not support the feature to run multiple ngspice simulations.
Support for such action should be added
- where multiple simulations of different projects are done
- where multiple simulations of the same project are done

Default curve fitting problem in Python Plot

The plot of python plot does not replicate that of ngspice for parameter sweeping instead looks something like a raster scan.

Python error during eSim2.3 on Ubuntu 23.04

Hi,

I'm trying to install eSim2.3 on a fresh and updated Ubuntu 23.04.
I'm quiet a newbe with the terminal / Ubuntu, but forced to use it to install eSim2.3

After using these lines, $ chmod +x install-eSim.sh and $ ./install-eSim.sh --install
I got a seemingly Phyton error. Is there a way to solve this easily?

Ps, in about a week I got more time to play around with stuff, now waiting for a new hip and need the pc in hospital.
Afraid to screw things up.

Thanks in advance.

Thanks.

Install script uses old version of kicad ppa

Script uses old version of kicad ppa
I have kicad5.1.9 installed already
So i changed it to the new one for myself

Made these changes:

function addKicadPPA
{

#sudo add-apt-repository ppa:kicad/kicad-5.1-releases
kicadppa="kicad/kicad-5.1-releases"
findppa=$(grep -h -r "^deb.*$kicadppa*" /etc/apt/sources.list* > /dev/null 2>&1 || test $? = 1)
if [ -z "$findppa" ]; then
    echo "Adding KiCad-5 PPA to local apt-repository"
    if [[ $(lsb_release -rs) == 20.* ]]; then
        sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 83FBAD2D910F124E
        sudo add-apt-repository --yes "deb [trusted=yes] http://ppa.launchpad.net/kicad/kicad-5.1-releases/ubuntu>
        sudo touch /etc/apt/preferences.d/preferences
        echo "Package: kicad" | sudo tee -a /etc/apt/preferences.d/preferences > /dev/null

and i also changed:

echo "Installing KiCad..........................."
sudo apt-get install -y --no-install-recommends kicad=5.1.10*
if [[ $(lsb_release -rs) == 20.* ]]; then
sudo add-apt-repository -ry "deb http://archive.ubuntu.com/ubuntu/ bionic main universe"
fi
