Hi,

I'm just leaving a simle note here.

And you are not supposed to. lilypond is not a program to create or edit 
.ly files. It is only there to read those files and produce pdfs and 
midi files.

The command
lilypond THE_FILENAME.ly
is used to create a pdf using an existing file named THE_FILENAME.ly
as input!

Here is a simple figure. Programs are inside bars (|program|) and take 
input from the left and output to the right.

With frescobaldi the data flow looked something like this
|frescobaldi| -> THE_FILENAME.ly -> |lilypond| -> THE_FILENAME.pdf
where the middle parts were invisible to you, because frescobaldi was 
made that way, to hide that part. You just interacted with frescobaldi 
and used the pdf at the end.

If you change away from frescobaldi, the middle part becomes visible 
(i.e. you have to "do more"):
|nano       | -> THE_FILENAME.ly -> |lilypond| -> THE_FILENAME.pdf

Now you have to create the file THE_FILENAME.ly explicitly yourself with 
some program, possibly nano, and then call lilypond THE_FILENAME.ly so 
that lilypond creates the pdf file from THE_FILENAME.ly.

Now you can replace nano by your favourite (working) editor, so once the 
gtk stuff is fixed, you may even use gedit in the future.

Hope that helps.

my home folder?

Do you mean the pdf?
I'd guess it already is in your home folder: If you just started your 
terminal before executing
guix shell lilypond nano mercurial timidity++  and the other commands,
THE_FILENAME.ly should be in your home folder (/home/gfp I guess). And 
executing
lilypond THE_FILENAME.ly creates the pdf file in the same folder.

Here is how to copy a file:
cp source.file dest.file

Example:
cp THE_FILENAME.pdf ~/Dokumente/

This will copy THE_FILENAME.pdf to the Dokumente directory.
This assumes THE_FILENAME.pdf is in your current working directory of 
your shell.


(That just means you're in that directory with the shell. The command 
`pwd` prints the current working directory. With cd you can change 
between working directories:
$ cd   # this changes to your home directory
$ cd Dokumente  # go into ~/Dokumente, which is Dokumente inside your 
home directory
# you can swith down multiple directories at once
$ cd Musik/Noten # go into ~/Dokument/Musik/Noten
$ cd ..  # go one level up, back into ~/Dokument/Musik
$ cd ~/Desktop/Projekt/Musical # jump to Projekt Musical inside Desktop
$ cd ../.. # go two levels up to Desktop

Note, these examples assume that those directories even exist. If one of 
those doesn't, cd will print an Error:
bash: cd: Musik/Noten: Datei oder Verzeichnis nicht gefunden
)

Example 2: If THE_FILENAME.pdf was for example on your desktop, you could do
cp ~/Desktop/THE_FILENAME.pdf ~/Dokumente/songbook-v0.1.pdf
to copy it to Dokumente and give it a different name at once.
