Wow, I haven't seen one of those in a _long_ time -- probably about 45
years. I think the first FORTAN implementation I used was WATFIV,
which had just introduced the character type. But, books/classes on
FORTRAN all still covered Hollerith constants.
The IMAP protocol uses a similar kind of construct (the length is
enclosed in braces)
Even ignoring the maintenance difficulty, I don't think it's possible to
syntax highlight something like that on most common editors.
The best solution I can think of is to have a text editor designed to
parse a string literal, spawn a nested editor with the unescaped
contents of that string literal, and then re-escape it back to place in
the code. If we had that, then we wouldn't even need raw strings.
Yes exactly, it would be cool to have such a satellite app
which can escape and unescape strings according to rules.
And which can also convert unicode literals to their ascii
analogues and back on the fly, this would very useful
for programming.
Probably it is a good idea to even include such thing
in Python package. So it would be a small standalone app
running parallel with text editor making it to copy paste strings.
I'm sure it's possible in, say, Emacs.
The editor that I use (EditPad Pro) can call external tools, so I could:
1. Select the string literal (easy when it is syntax-aware, so I can
select all of the literal with 2 keypresses).
2. Call the external tool (1 keypress), to open, say, a simple tkinter app.
3. Edit the unescaped text (unescape with ast.literal_eval, re-escape
with 'ascii').
4. Close the external tool, and the selection is replaced.
