I committed several improvements to Euphoria MVC today.

https://github.com/OpenEuphoria/euphoria-mvc

• Built-in web server now supports GET and POST requests.
• Model library can now query/insert/update/delete objects.
• Template library does better at handling more expressions.
• Route parser now accepts arbitrary regex patterns for type-checking.
• Added libraries for parsing HTML and JSON documents.
• Easily save and load configuration files (in INI format).
• Wrappers for MySQL (or MariaDB), SQLite3, and libcurl.
• Updated documentations!

Update 11/15/2020:

• Added SQLite3 library and wrapper

Update 11/23/2020:

• Added HTML parser

Update 11/28/2020:

• Overhauled mvc/config.e

There's still a lot to do. But I'm still working on it. I'm not dead yet!

Agreed! Can't wait to see this when it's finally ready to be rolled out.

Fingers crossed.

I added a CURL wrapper today! (Well, I actually wrote it several years ago to make the existing euweb work with reCAPTCHAv2.) Updated release to v1.9.0.

That's funny Greg. I built an importer that would load in the constants and functions from a C- header file and create a Euphoria E file for in order to create a curl wrapper. Is it necessary to use MVC in order to use the CURL function?

The failing t_net_http.e has been a thorn in my side for years now and it is a bigger waste of time to me to re-implement what CURL from (Euphoria MVC) already does in Euphoria than to leverage CURL it in order to fix t_net_http. I wouldn't mind if std/net/http.e went away completely at this point and I don't see anyone really using it. I am the kind of person who doesn't like to remove something from a library once it is already in there, though. What do you think?
Forked into: RM std/net/http.e?

Where should local CSS files be located to be used with the development server ?

Yeah I need to add a feature for serving files directly from a local directory. I'd also like to add an option for "base directory" so you can change it from current directory.

In the mean time, I've at least added send_file() and download_file() which are shorthand for verifying a file exists, looking up its mime-type, and then sending the required headers.

include mvc/app.e

I pushed the commit for adding send_file() just now: https://github.com/OpenEuphoria/euphoria-mvc/releases/tag/v1.12.1

You can use this to add a static route handler to your application. Then just put everything in /static/, like /static/css/, /static/js/, etc.

Edit: Or you can add a route pattern for specific directories as I've indicated below.

include std/map.e 
include mvc/app.e 
 
include std/filesys.e -- for canonical_path() 
include std/search.e -- for search:begins() 
 
-- 
-- Route handler for files in /static/ 
-- 
function static( object request ) 
 
    -- get the path to the requested file 
    sequence path_info = map:get( request, "PATH_INFO" ) 
 
    -- 
    -- Note: path_info will always start with 
    -- "/static/" thanks to the route handler. 
    -- 
 
    -- ensure the local file is an actual full path 
    sequence local_file = canonical_path( "." & path_info ) 
 
    -- ensure the local file exists in current directory 
    if search:begins( current_dir(), local_file ) then 
 
        -- go ahead and send the file to the browser 
        return send_file( local_path ) 
 
    end if 
 
    -- tell the browser the file doesn't exist 
    return response_code( 404 ) 
end function 
-- 
-- Note: this pattern should resolve to "static" and find the function above. If not, you can call 
-- app:route("pattern", "func name") or even app:route("pattern", "func name", routine_id("func name")) 
-- 
app:route( "/static/.+" ) 
 
-- Or add a handler for specific directories like this: 
app:route( "/(css|js|fonts|images)/.+", "static" )

    sequence local_file = canonical_path( "." & path_info ) 
 
    if search:begins( current_dir(), local_file ) then 
 
        return send_file( local_path ) 
 
    end if 

local_path is not defined. I thought it could be local_file instead but that's wrong:

2020/11/26 11:41:13  INFO static@mysql_users.ex:22 path_info = "\"/static/css/w3.css\"" 
2020/11/26 11:41:13  INFO static@mysql_users.ex:31 local_file = "\"C:\\\\Users\\\\duro\\\\Documents\\\\mysql_users\\\\examples\\\\static\\\\css\\\\w3.css\"" 
2020/11/26 11:41:13  INFO client_handler@server.e:140 "127.0.0.1" "GET" "/static/css/w3.css" "404 Not Found"

Thank you Greg,

I updated my MySQL example for euphoria-mvc: http://jean-marc.duro.pagesperso-orange.fr/mysql_users.zip

euphoria-mvc is a real game-changer in web programming for me.

I overhauled mvc/config.e today.

https://github.com/OpenEuphoria/euphoria-mvc/releases/tag/v1.13.0

If your configuration looks like this:

# app.cfg 
[database] 
name = mydatabase 
username = dbuser 
password = abc123 
host = db1.example.com 

You can load it in your app like this:

include mvc/config.e 
include mvc/logger.e 
 
if not load_config( "app.cfg" ) then 
    log_crash( "Failed to load configuration" ) 
end if 
 
sequence db_host, db_name, db_user, db_pass 
db_host = get_config( "database.host" ) 
db_name = get_config( "database.name" ) 
db_user = get_config( "database.username" ) 
db_pass = get_config( "database.password" ) 

And it will even preserve comments when saving!
