sparforte can't possibly build on freebsd. This patch fixes one problem:

Another problem is group_member function isn't available on freebsd (c_os.c) but it's used unconditionally in C_is_executable_file. That's a problem that requires opening another issue I think.
Currently the dash or (soft ?) hyphen - is considered at least in some situation, as a word separator by the interpretor. Even without space.
Names of commands not enclosed in " " can't be interpreted rightly.
If that space could be the only word separator, it would make sparforte more usable, for more users.
Sparforte currently doesn't build for me since switching from GCC 11.2 to GCC 13.2
The first issue was stopped on a treat-warnings-as-errors here:

I got past that by adding the "-gnatd.E" flag.
But a bit further it crashed again due to a compiler ICE:

In any case I would be interested to hear if these issues can be reproduced by others.
issue 1: The v2.2 tag refers to a commit "fixing conflict in todo file" (8a4d5f3) that doesn't seem to be in the master branch. Perhaps the tag was pushed but the tree was not?

Firstly, I think it would be nice if I could just compile without MySQL, since both fundamental functionality and compile-ability are essential to the usefulness and growing popularity of this wonderful idea and scripting kit. The problem I have right now and that is likely very common elsewhere is that MySQL does not compile and it seems that it is a source code issue.
Isn't there a pure Ada implementation of SQL? Ada and MySQL are practically cousins, so why is MySQL being loaded from the modern C libraries? If it is for some general compatibility with library changes over time, I'd rather have pure Ada rudimentary database support. Anyway, the most practical choice I have right now is to get MySQL running. Here is the failure output of the compiler:

Hi Ken,
I noticed you revert one of my patch regarding the database configuration. But the current logic is not right.
I have both MySQL and PostgreSQL installed in the system, given the following commands:
configure --arch=x86_64 --without-sql
or
configure --arch=x86_64 --without-postgres
will result in no database being configure.
I added a line just before the database configuration to show the variables' value:
for --without-mysql
NO_MYSQL 1 NO_POSTGRES
HAS_MYSQL HAS_POSTGRES 1
for --without-postgres
NO_MYSQL NO_POSTGRES 1
HAS_MYSQL 1 HAS_POSTGRES
As the test [ -z "$NO_MYSQL" -a -z "$NO_POSTGRES" ] will always failed when you have one of the without parameter set, "-z" only test whether the variable is empty or not, it does not care it contains "0" or "1".
When you have --without-mysql defined, HAS_MYSQL is always empty and when --without-postgres is given, HAS_POSTGRES is always empty.
If system has only one DB installed, and run with "./configure --arch=x86_64" , will result in calling the APQ configure with full DB support, and it will prompt when one of the DB is not found, breaking automatic building script.
Using HAS_MYSQL and HAS_MYPOSTGRES will result in clearer logic flow of configure the APQ lib.
All issues based on 2eb28f7:
the rules around end loop;, end if;, end <name>;, ... could be made more lax such that end; would be enough.
Is there a way to read a number in arbitrary base? Specifically numerics.value does not understand 0x... notation.
Huh? Shouldn't it be an exception?
raise constraint_error with "String repr does not start with 0x";
^--------------^ constraint_error is a variable not an exception
case 20 rem 16 is
^^ identifier expected, not a number
case n rem 16 is
^-^ is expected
=> ? 20 rem 16

Good day to everyone, I came across SparForte while surfing the internet for teaching resource that could be used or adapted in my Ada programming classes. Beginners at College level learners, being exposed to the Ada language first. I think SparForte will be a solid pathway for incremental programming within Ada as a mix-in to start off gradually. Many thanks!
Question: Is there an example or some examples of using SparForte inside an Ada code?
I saw a quote in the documentation==> "AdaScript scripts should run with little difficulty under Ada". So I was wondering if I could see example of an how to. Many thanks!
I already register on SparForte mailing list but I could not post yet, waiting for approval, hence my coming here to post at the development portal.
Also, I saw an attempt and communication on Alire regarding SparForte but I could find it in the index nor how to go about using Alire.
I strongly believe that using SparForte using will be a great success in introducing beginner to programming in Ada, it will allay and remove the fear that faces most starter and beginner positively.
Many thanks for your all your efforts and many years of valuable time that went into SparForte.
Hear from you soon.
God blesses!!!

In pegasock-smtp.email the content string does not get sanitized correctly. Any line in content that starts with a period should be made to start with a double period to "escape" it. https://github.com/kburtch/SparForte/blob/master/src/pegasock/pegasock-smtp.adb
put_line( mysmtp.socket, content );
put_line( mysmtp.socket, "." );
Also, the date is not sent but with GNAT.Calendar.Time IO it should be pretty simple

Hi,
Sorry if this is a bit of a laundry list but these are a small collection of issues I've encountered early on when using sparforte.
#!/bin/spar
put(123.45, "##9.99");
% spar picture_string_exception.spar
raised ADA.IO_EXCEPTIONS.LAYOUT_ERROR : a-teioed.adb:300
This also crashes the shell when used directly which wouldn't be ideal if spar was being used as the user's main shell.
#!/bin/spar
ragma annotate(summary, "range check error");
procedure range_check_error is
procedure usage is
begin
put("usage: ") @ (source_info.file);
command_line.set_exit_status(0);
end usage;
begin
if $# /= 0 then
usage;
return;
end if;
end range_check_error;
% spar range_check_error.spar
raised CONSTRAINT_ERROR : scanner.adb:1992 range check failed
This issue was discovered when trying to elaborate on how spar -gc handles various errors and warnings. It turned out that simply running the script with spar resulted in the same error.
#!/bin/spar
procedure wrong_error_style is
error: string;
begin
loop
error := get_line
exit when error = ";
end wrong_error_style;
% spar -gc wrong_error_style.spar
wrong_error_style.spar:8:1:[11/19 11:29:13] missing double quote
I would have expected:
wrong_error_style.spar:8:1: missing double quote
If I wanted to add timestamps I could use ts from moreutils or svlogd -tt from runit.
#!/bin/spar
procedure misleading_line_match is
error: string
begin
loop
error := get_line
exit when error = "";
end misleading_line_match;
% spar -gc misleading_line_match.spar
misleading_line_match.sp:5:1: ';' expected
The missing ';' should be reported on line 2, column 16, but it is being reported on the line containing begin.
For any example which delcare commands as such:
ls : constant command := "/bin/ls";
I get the following error:
ls : constant command := "/bin/ls";
^^ command variables must be limited
Thanks
