I see some tutorials online but they only show how to install git onto Cygwin AS you are installing Cygwin. I already have cygwin installed and customized so I'd prefer not to repeat that step. How do I install the git framework so I can use it for github?
Thank you.
In the world of Cygwin, there is really no such thing as only installing a package AS you are installing Cygwin. Cygwin was inherently designed with a setup.exe to be run multiple times when necessary.
There are thousands of packages available in the Cygwin repo mirrors. From what you are saying, it sounds as if you had a single go-round with the setup file and then planned to never install any additional available packages or upgrade them in the future. This is what the Cygwin setup file is specifically used for.
If you don't currently have Git installed in your particular Cygwin environment, just run setup.exe again and select the package. It should automatically detect your current installation directory and package directory and previously-selected mirror. When you mark the Git package for installation, it will automatically download all dependencies, just like apt-get or any other *NIX package manager.
There is also an abandoned project called apt-cyg that I still use religiously, especially on remote systems over SSH in order to avoid the GUI setup.exe. apt-cyg is basically a shell script that will install your package directly from the command line, apt-get-style. It requires wget and subversion, but after the 30 seconds it takes to setup, you'd just run apt-cyg install git. It also installs dependencies, just like the GUI setup.exe.
There is also a similar alternative if you install Cygwin via Chocolatey package manager -- you can also install cyg-get (I believe it's called). The syntax is a bit different -- something like cyg-get git. I don't really like this method, because it differs from apt-cyg in the fact that it actually uses the setup.exe and just automates the process so that you don't have to click anything. I don't use this method, because the last I checked, Chocolatey only supported 32-bit Cygwin installs, which is also what the cyg-get package looks for.
apt-cyg may be abandoned, but it has yet to disappoint, and if I know what I'm looking for, I always prefer it over running the setup.exe for package installation.
It looks like the project has been picked back up and is under active development again: https://github.com/transcode-open/apt-cyg
It appears this version requires lynx to install. I don't know. I still just use the original version on Google Code that worked just fine the last I checked: https://code.google.com/p/apt-cyg/
Edit: There has been a new Cygwin package manager out for awhile called cyg-get that can be installed via Chocolatey.
I'm not sure if it only works for Chocolatey-installed Cygwin installations or not, as Chocolatey doesn't install Cygwin in the normal locations anymore by default. Feel free to comment, but cyg-get is now my Cygwin package manager of choice unless I'm running an older installation of Cygwin that was not installed by Chocolatey. I avoided it for a while because they only supported 32-bit installations, but I can confirm that Chocolatey now supports 64-bit installations of Cygwin, and the cyg-get package manager works perfectly with it. I have a function sourced from my ~/.bashrc where I can use either apt or apt-get (with or without the install parameter, and it will just call cyg-get.bat with the programs I have specified to install.

I'm using wsl and it runs codes in vscode pretty fine and I have different libraries which I installed through pip and conda in wsl but when I run that code using vscode itself it doesn't recognize the libraries or even pip itself.
I don't have any other environment.
I should add that I installed the packages globally using conda install ... or pip install ... in base environment and I only have base environment and I run my code through code . and I also have python and remote wsl extensions installed in my vscode.
what can be the problem?
I don't have much personal experience with this, but I found some useful information in this Stack Overflow question (even though it doesn't utilize conda), along with https://code.visualstudio.com/docs/remote/wsl-tutorial#_python-development.
I also found this blog post useful, even if it doesn't cover WSL.
In short, make sure you:
Have installed the Python extension (by Microsoft) in VSCode. This is critical for being able to detect and select the Python interpreter. You don't mention having this in place, so I believe this is your likely problem.
You have done this already, but including it for others who might read this later -- Install the Remote - WSL extension (or the Remote Development extension pack) in VSCode.
You are also doing this already -- Start VSCode from inside your WSL distribution. Alternatively, you can start VSCode from Windows and then select the Remote WSL - Reopen Folder in WSL from the Command Palette (also accessible from the "Remote" Status Bar).
In VSCode, open the Command Palette with Shift+Ctrl+P, search for the Python: Select Interpreter command, and you should find your Conda environment in the list.
After selecting this, you should find that your project is using the interpreter and modules that you have installed via conda.
One thing I did to overcome this issue is go to Extensions -> Local (You should have two tabs there, Local and WSL:DISTRO) DISTRO refers to whatever DISTRO you're using, you will see that some of the local extensions are disabled in the current workspace (WSL) and there is a little cloud icon in the WSL:DISTRO tab that says install Local Extensions in WSL:DISTRO once you click that it will let you choose which extensions to install and you should be good to go!
I am trying to install the Raku module «Gnome::Gtk3» module on a Windows pc, without success.
Powershell> zef install Gnome::Gtk3
This fails with a lot of "Cannot locate native library"-messages.
I have installed Raku with choco, along with git. And have fixed the path.
That alone took quite some time to figure out, due to missing documentation.
I have installed Gtk, as described here: https://www.gtk.org/docs/installations/windows
But Raku is unable to locate the libraries. Is this something that can work, or do
I have to use the Windows Subsystem for Linux?
(I am aware of the «GTK::Simple» module, but cannot use that as a replacement as it lacks support for keyboard interrupts - which I need.
I have installed it, as it states that it installs the GTK dll's as well.)
In order to make this kind of modules work, you need the -dev version of the library, that is, the DLLs which are actually the ones that NativeCall uses. This tutorial shows how to set them up for C++ and Python, Raku shouldn't be too different.
This now installs on MSYS2, Windows 10. First download the latest version of rakudo from here and extract the zip file to e.g. C:\rakudo-2020.11. Then install MSYS2, and when finished open the MSYS2 terminal window and install the following packages:
$ pacman -Syu
$ pacman -S base-devel gcc git libcrypt-devel libreadline
$ pacman -S mingw-w64-x86_64-gtk3
$ pacman -S mingw-w64-x86_64-toolchain
Then add the following to the MSYS2 ~/.bashrc configuration file:
export PKG_CONFIG_PATH=/mingw64/lib/pkgconfig
export PATH="$PATH:/c/rakudo-2020.11/bin:/c/rakudo-2020.11/share/perl6/site/bin"
export PATH="$PATH:/mingw64/bin"
Save the updated .bashrc and reload it from the MSYS2 terminal prompt:
$ source ~/.bashrc
Finally, install Gnome::Gtk3:
$ zef install Gnome::Gtk3
I'm trying to install Scalatra on windows seven and need to change a file to executable...the Scalatra documentation says to do this, which is unix. What is the windows equivalant?
chmod u+x srt
You can simply open the relevant folder with a unix command prompt (I use git bash) and execute the unix commands from there
To get scalatra-sbt going on Windows, either port you own sbt.bat from scalatra-sbt, or install chmod via cygwin.
Assuming you've successfully installed the rest of Conscript and giter8, you can start a project that downloads scalatra-sbt. From there, one can look through the ./sbt source, and port the bash script functionality to your own windows specific script, or install a unix compatibility layer into Windows. If you go down the "windows specific script" route, perhaps the scalatra-sbt would appreciate the project contribution.
The "unix compatibility layer" route will eventually allow you to run ./sbt. chmod is a unix command line function, and is provided in a default package of the tool set cygwin, which provides a complete lunix-like environment. Once inside a cygwin terminal, you can chmod your file, as mentioned in the scalatra-sbt first project.
Diving into the contents of ./sbt from scalatra-sbt, this is actually unix script wrapper around the scala build tool (also referred to, confusingly, as sbt). If while trying to run ./sbt you get strange '\r' errors, install the cygwin package dos2unix, and then run it on the sbt file. If you run into any "which: no curl in..." or "which: no wget in..." errors, go back to the cygwin installer, find those packages such as wget, and then install those programs.
By the way, the last thing the scalatra-sbt script runs is the Scala build tool. The Scala build tool sbt itself has many reported issues with cygwin's default configuration, so you will likely need to do more research. Depending on what issues you're running into on your specific setup, you may need to make changes to the end of the ./sbt script to adjust the parameters used to launch the Scala build tool.
I'm trying to wrap my head around virtualenv and pip still.
If I use pip to install a library, it doesn't matter where I 'cd' to, because it installs the libraries in the same place right (which i dont even know where that is)? So I guess my question is, when I install something with pip, how do I make sure it only installs that library inside of my virtual environment? Do I need to cd to that directory first? or is there a command I'm supposed to use with pip to make sure it only installs to the virtualenv project I'm working in?
Activate virtualenv first:
source virt_name/bin/activate
Then after that, install the libraries:
pip install module_name
Note: Don't use sudo with pip because sometimes it will assume you want to install in /usr/local/lib/site-packages.
Generally speaking, if you do not use virtualenv --system-site-packages to create your virtualenv, you should be only working with your per-environment packages.
Providing you run the activate script before installing anything.
i.e. Do the following, if you want to install something in your virtualenv.
Run activate script
Windows: [ve_directory]\Script\activate.bat
Linux: source [ve_directory]/bin/activate
pip install [your requirements]
I think it doesn't matter where your current working directory is.
Reference:
http://www.virtualenv.org/en/latest/#the-system-site-packages-option
When you create a new environment with virtualenv, among other things it creates a bash script venv/bin/activate (where venv is the folder you specified when you created the environment; libraries are located there as well, by the way). When you run it in your shell the environment variables become arranged so that pip installs new libraries in this environment's folder. See virtualenv docs for details, section "activate script".
I have recently installed cygwin as I want to use (and learn) emacs and make it my regular text editor (as I use Notepad++ now).
The motivation for this comes from some sites like this:
http://batsov.com/articles/2011/08/19/a-peek-at-emacs24/
Also, I want to learn the internals of linux. I tried vi but its too CUIish for my taste. So I installed cygwin (with it's default emacs 23.3). But I wanted to try emacs 24 too so I want to install it side by side with cygwin's emacs 23.3. This can be done in a linux distro by installing emacs in /opt and making symlinks. But how do I install emacs binaries in cygwin?
From where do I get such binaries.
Currently I am using 'Emacs for Windows' seperately from cygwin, but it is hard to get it in a portable format. If I manage to install it in cygwin then my whole cygwin environment can be portable.
I generally try to install softwares so that they are portable as far as possible.
You can use the setup.exe that you used to install cygwin, to install Emacs as well.
