Single quotes not accepted by `print()` inside strings

[Marcos Cruz]

Hello.

I'm trying Ring 1.19 on Debian 12.5.

While I was writting a program, I got some errors because somehow single quotes
(') are not accepted by `print()` in strings delimited by double quotes (") or
backticks (`).

This is a confirmation test done using the REPL:

--------
ring:> print("he'llo")
Error (S1) In file: eval
In Line (1) Literal not closed
Called from other source code fileError (R42) : Error in eval() function
ring:> print(`he'llo`)
Error (S1) In file: eval
In Line (1) Literal not closed
Called from other source code fileError (R42) : Error in eval() function
ring:> print(`he'll'o`)
heError (R24) : Using uninitialized variable: l
ring:> c = `he'llo'`
ring:> print(c)
heError (R24) : Using uninitialized variable: l
--------

Double quotes are parsed as expected:

--------
ring:> print(`he"ll"o`)
he"ll"o
ring:> print(`he"llo`)
he"llo
ring:> print('he"llo')
he"llo
ring:> c = `he"llo`
ring:> print(c)
he"llo
--------

Single and double quotes work fine with `put`:

--------
ring:> put `ho"la`
ho"la
ring:> put `ho'la`
ho'la
ring:> put 'ho"la'
ho"la
ring:> put "ho'la"
ho'la
--------

The examples included in sections 6.1 ("Print() function") and 18.1 ("String
Literals") of the documentation make me think this is a bug. Or am I missing
something?

Thank you.

Hello Marcos

Thanks for the report :D

This is already reported before by Gary in 2024.01.16 and fixed in Ring 1.20

Original post/report: String Interpolation error (google.com) 

You can get Ring 1.20 from GitHub and build Ring from source code.

URL:  ring-lang/ring: Simple and flexible programming language for applications development (github.com)

Greetings,

I see. Sorry I didn't search the group before reporting. Glad to know
the bug has been fixed.

I'll do it. Thank you.

Hello Marcos

You are welcome :D

To do this quickly

1 - Get a copy from Ring source code from GitHub 

git clone https://github.com/ring-lang/ring.git

2 - Instal dependency

cd ring/language/build

./installdep.sh

3 - Build all of the extensions/tools & Ring compiler/vm

cd ring/build

./buildgcc.sh

4 - Final Step

cd ring/bin

sudo ./install.sh 

Now Ring is installed and you can run Ring Notepad

ringpm run ringnotepad

Note: We will improve these steps along the time

Thank you.

One year ago, when I tried Ring for the first time, I was surprised that
the compilation and installation process needed several specific steps,
not just the usual `make` or similar.

Then I wrote a fish shell script in order to automate the steps and fix
some issues. For example: some script names were outdated in the
instructions I found in the website; some Linux scripts didn't run on
Debian because they were written in bash but didn't have a shebang,
while my default shell is fish, so I had to execute them with an
explicit `bash`; other scripts didn't run on my system because they
contained Windows end-of-line codes, and my script had to convert them
first.

My script worked fine with the light release of Ring, which was the
first one I tried; later I modified it in order to detect and support
also the Ubuntu full release, which was simpler to compile; finally,
following your kind instructions, I have updated my script to detect and
compile also the repo, what made the process even simpler.

I have used my script again, without any change, in order to update Ring
from version 1.20 to 1.21, compiling from my repo clone.

I think my script could be useful to others. Anyway, it's interesting
because it shows how peculiar the installation process is, at least in
my case…

Here you are:

[I sent this message 7 days ago, which the code pasted, but it didn't
arrive; now I send it again with the code attached.]

Hello Marcos

>> " I think my script could be useful to others."

Thank you very much for sharing :D

Note: we have new scripts that build everything on Linux like this one: ring/build/buildgcc.sh at master · ring-lang/ring (github.com)
