Subject: nano recognition of syntax files
Content-Type: text/plain; charset="utf-8"
Okay, so i found that there are syntax files (or i think that's what these are...) in the /usr/share/nano folder on linux, are these meant to be selected or moved so that someone could use "Esc + 3" to comment/uncomment a section of text? How does this work?

Thank you Benno, I'm pretty new to programming. What is a "syntax" to nano? Does something about a file you create tell nano that a filehas a particular syntax? Not sure how that works from a practical vantage point:
syntax name ["fileregex" ...]
Start the definition of a syntax with this name. All subsequent
color and other such commands will be added to this syntax, until
a new syntax command is encountered.

Subject: Request help in changing default comment string for nano
Content-Type: text/plain; charset="utf-8"
Hello everyone, nano is a great text editor overall, i like it much better than vim and i have been using it for the past 6 months. However, i would like to know how you can change the comment character from # to something else for a different programming language. The documentation says this:
-
- comment "string"
-
Use the given string for commenting and uncommenting lines.If the string contains a vertical bar or pipe character (|),this designates bracket-style comments; for example, "/*|*/" forCSS files. The characters before the pipe are prepended to the line and thecharacters after the pipe are appended at the end of the line. If no pipecharacter is present, the full string is prepended; for example, "#" forPython files. If empty double quotes are specified, the comment/uncommentfunctions are disabled; for example, "" for JSON.The default value is "#".
I try to put
comment "//"
in my .nanorc file, but the program just gives me an error and the default comment remains a #. What's the proper way to change this setting? I tried to fool around with it but i just get red text, which is nano's way of saying that it's an error.
Thanks

You set the comment character in the syntax file for the relevant language.

There is no way to change the default comment character _globally_ -- you
can only change the comment character per syntax. As 'man nanorc' says:
For each kind of file a separate syntax can be defined via the following
commands:
syntax name ["fileregex" ...]
Start the definition of a syntax with this name. All subsequent
color and other such commands will be added to this syntax, until
a new syntax command is encountered.
(And the 'comment' command is one of these subsequent commands.)
