It turned out to be trickier than expected as MicroSIP uses the old INI file format for passing in the command.

Upon reading the source, I saw that MicroSIP uses the function GetPrivateProfileString to read the ini file and this was never designed to cope with long strings with spaces in them.

I came up with a solution to use the good old 8.3 filename format in windows for the path names.

To discover the file names you can use dir /X. Edit the cmdCallAnswer line of the micrisip.ini file.

cmdCallAnswer=C:\Users\foo bar\AppData\Local\Microsoft\WindowsApps\python.exe c:\Users\foo bar\launch_browser.py https://example.com/path

becomes something like:

cmdCallAnswer=C:\Users\FOOBAR~1\AppData\Local\Microsoft\WindowsApps\python.exe c:\Users\FOOBAR~1\LAUNCH~1.PY https://example.com/path

Also, MicroSIP works perfectly well under wine too!

This is the script I wrote for launching the browser:

import sys
import webbrowser

def main():
    if len(sys.argv) < 2:
        print("Usage: launch_browser.py <URL> [param1=value1] [param2=value2] ...")
        sys.exit(1)

    base_url = sys.argv[1]
    query_params = sys.argv[2:]

    # Construct the query string
    query_string = "".join(query_params)

    # Combine the base URL and query string
    full_url = f"{base_url}{query_string}"

    # Open the default web browser with the constructed URL
    webbrowser.open(full_url)

if __name__ == "__main__":
    main()

I hope this helps someone and Free Palestine! Stop the genocide!

Dim WinScriptHost
Set WinScriptHost = CreateObject("WScript.Shell")
strCmd = "C:\cygwin\bin\bash --login -c '/usr/local/bin/emacsclient -c -a /usr/local/bin/emacs.exe"
    If WScript.Arguments.Count = 1 Then
        'strCmd = strCmd & " " &"""" & WScript.Arguments(0) & """'"
		wScript.Echo strCmd
	else
		strCmd = strCmd & "'" 'close single quote
    End If
WinScriptHost.Run strCmd,0
Set WinScriptHost = Nothing

Save that script somewhere and then make a Windows Shortcut to it but incle the wscript.exe in the target:

C:\Windows\System32\wscript.exe C:\Users\jason\launchemacs1.vbs

You can then launch it from the Start Menu in Windows 7.

Free Palestine!

Installing cygwin

First, install cygwin.
Then, install the very nice tool apt-cyg which makes package management much easier in cygwin.
Then to save yourself lots of agony of trying to work out which cygwin packages you need to install to be able to compile emacs, here is the list of all the packages I have installed. It may be a little bit of overkill but it will save you time. I obtained the list like this:

jason@jade ~
$ apt-cyg show | tr '\n' ' '

Install them with:

$ apt-cyg install

Go and have a cup of tea while its installing.

git clone git://git.savannah.gnu.org/emacs.git
cd emacs
./configure --with-w32 #  to ditch gtk and the concomitant gtk bug, thanks jlf
make

If make is successful, test the build by running emacs from the src directory:

src/emacs -Q

If that worked ok, you can:

make install

Setting up your home

I like my cygwin home directory to be the same as windows %USERPROFILE% so I set the environment variable HOME=%USERPROFILE%.

Set up a shortcut to launch emacs

Make a shortcut to c:\cygwin\bin\run.exe on your desktop, and rename it to emacs.
Edit the shortcut to:
Target: C:\cygwin\bin\run.exe /usr/local/bin/emacsclient "-c" "-a" "/usr/local/bin/emacs.exe" #
Start in: %USERPROFILE%
The target part makes sure emacs launches a new window whether or not its already running. If it is already running and as a server, it will create a new frame connected to the server.
The start in part makes sure the new instance’s default-directory is your home directory which I think makes most sense for when you are launching from a shortcut.
Drop the shortcut onto your start menu. You should now be able to launch emacs from the start menu, or by pressing the Windows key and typing emacs.
