P.S. easier to test the 'bug': download wgrib2.exe and all cygwin dll at:

echo '\x1B[32m' + ' Hello foo:  after wgrib2 use ' + '\x1B[0m'

The segmentation fault in free_objects() occurs due to b_obj_string fields being errorneously freed twice, which results in those objects becoming invalid.

The fields in question are name in b_obj_closure, name in b_obj_func, name in b_obj_class and mode & path in b_obj_file.

Additionally, leaks occur whenever copy_string() is called with an empty string, as well as unnecessary b_obj_string creation in io_module_(stdin|stdout|stderr) for the field mode (which is already created during call to new_file).

After fixing that, there should be no longer a segmentation fault, although there are approximately 10 blocks that I suspect are created during calls to strdup.

You can find most of them with the regex '(->|.)\b(name|mode|path)\b', i.e. with grep.

Platform

Blade Version

v0.0.82 (from the releases)

Issue

Using the example application in the README:

import http
import json

var server = http.server(3000)
server.on_receive(|request, response| {
    response.headers['Content-Type'] = 'application/json'
  response.write(json.encode(request))
})

echo 'Listening on Port 3000...'
server.listen()

Results in the error: Unhandled Exception: module '_ssl' not found.

Is it not possible to run an HTTP server without SSL?

Allow users to try the language from a REPL hosted entirely in the web browser.

Both blade_getopt.c and blade_getopt.h have file headers which show that they have been distributed under the LGPL v2.1 or later license. In the CMakeLists.txt file, these files are statically linked to the blade binary. Therefore, the whole project falls under the terms of the LGPL v2.1 or later license.

To keep this project MIT only, these files must be removed entirely.

Often times what gets me and many other people to not look further into projects, is the lack of very minimal examples.
I think the README should contain a tiny example, so that people can get a feel for the language right away. Since the language is very small, it doesn't really make that much sense to have a hello world example.

I propose something like:

def sum(numbers) {
    var result = 0

    for num in number {
        result += num
    }

    print(result)
}

sum([1, 2, 3, 4]) # this will print "10"

This presents the developer with information about:

• functions
  • defining functions
  • calling functions
  • function arguments
• variables
• for loops
• assignment
• printing
• arrays
• single-line comments

Issue closed at #174. Cocoa library renamed to html to fit into the built-in libs convention.

Creating documentation not only for Blade, but also for user-made modules would be nice with regular comments.

/* doc
  prints the sum of `a` and `b`
*/
def add(a, b) {
  print(a + b)
}

# doc prints the resulting value of `a` subtracted by `b`
def sub(a, b) {
  print(a + b)
}

Then the output could look like:

def add(a, b)

prints the sum of a and b

def sub(a, b)

prints the resulting value of a subtracted by b

This would allow anyone to add documentation to their own application / module very easily. It would also make it easy to create a tool that generates the documentation. This also groups documentation together with the specific code, making it easier to navigate and edit. It would also be familiar to devs, that are used to adding documentation with ///.

For the documentation generator, I guess these comments could be added to a map / dictionary like so:

{
  'def add(a, b)': 'prints the sum of `a` and `b`',
  'def sub(a, b)': 'prints the resulting value of `a` subtracted by `b`',
}

Where depending on the input flags, this dictionary can easily output the documentation in markdown, HTML, JSON or something completely else.

A good catch by @galexite shows that the sources from which the hash functions in the hash module derived seems to use unattributed code from the PHP source.

This all needs to be purged and replaced with new implementations or MIT/BSD licensed code.

os: Windows 10/21H1
blade: 0.0.6/MSVC or MSYS2

Multi-line comments (at least at the script end) failed.
For MSYS2-compiled blade:

echo "Hello blade world"
/*
var a = 11111111111
*/

Result:

SyntaxError:
    File: bug_10.b, Line: 4
    Error: unexpected character ³
SyntaxError:
    File: bug_10.b, Line: 4
    Error: unexpected character £

For MSVC-compiled blade:

echo "Hello blade world"
/*
var a = 11111
*/

Result:

SyntaxError:
    File: bug_10.b, Line: 4
    Error at '*': expected expression

Depending on the length of the multi-line comment, the comment is taken into account or not.

Is your feature request related to a problem? Please describe.

print(10) in the REPL outputs 10nil
It does not look nice when printing, that it is followed by nil.

Describe the solution you'd like

print(10) should print 10 and not include nil.

This can be fixed by changing:
https://github.com/blade-lang/blade/blob/main/src/vm.c#L1549-L1553

Currently this is the code:

if (vm->is_repl) {
  echo_value(peek(vm, 0));
} else {
  print_value(peek(vm, 0));
}

I propose:

if (vm->is_repl) {
  // maybe have a variable to avoid peeking twice
  if (!IS_NIL(peek(vm, 0))) {
    echo_value(peek(vm, 0));
  }
} else {
  print_value(peek(vm, 0));
}

I'm curious as to why this is a thing. Is this a bug or is it for something like debugging? If wanted I can go ahead and PR this.

blade_termios.h has a file header which shows that it has been originally licensed under GPL v3.

This file must be removed to keep blade under the permissive conditions of the MIT license.

Describe the bug

When running <blade> -h, the help message is printed to stderr, ignoring if it is a failure or not:

src/blade.c

...
void show_usage(char *argv[], bool fail) {
  fprintf(stderr, "Usage: %s [-[h | d | j | v | g]] [filename]\n", argv[0]);
  ...
  exit(fail ? EXIT_FAILURE : EXIT_SUCCESS);
}

To Reproduce

Steps to reproduce the behavior:

1. Install blade
2. Run blade -h

Expected behavior

If it's not a failure, print to stdout.

Describe the bug

Whenever Blade is installed in a path with containing the . character (for example using the Autoinstall script), imports stop working.

To Reproduce

Steps to reproduce the behavior:

1. Install Blade using the Autoinstall script for Linux and OSX
2. Launch the Blade REPL
3. Try to import any library.
4. See error

Expected behavior

Import should work properly whether the application directory contains .s in it's path or not.

Additional context

This is due to how merge_paths in src/pathinfo.c currently works.

Hi everyone,

Let's use this issue to showcase our awesome projects based on Blade.

Regards.

Is your feature request related to a problem? Please describe.

As it stands, Blade classes are first class and can be used in almost anything including iterables, values and more. It will greatly increase consistency to have Blade classes support operator overloading from classes.

Proposed Solution

Since today, Blade classes can become iterators by implementing the @iter and @itern decorators, Blade can employ decorators for operator overloading support.

E.g.

class A {
    @+(a2) {
        return self.value + a2.value
    }
}

var a1 = A()
a1.value = 5

var a2 = A()
a2.value = 7

echo a1 + a2

The above sample code should print 12 to terminal.

Alternative Solution

As an alternative, we could use a keyword operator.

For example:

class A {
    operator + {
        return self.value + __arg__.value
    }
}

var a1 = A()
a1.value = 5

var a2 = A()
a2.value = 7

echo a1 + a2

This will at best require an extra conditionally valid keyword __arg__.

Description

I'm trying to compile bird, with on windows with MSVC 19.26 (cmake 3.20) but the build failed with an error error C2065: 'sha256_word': undeclared identifier

Here is the line that makes the error.
https://github.com/mcfriend99/Bird/blob/main/src/win32.c#L90

What I've done so far

Run the command and compiled with MSVS 2019

mkdir build && cd build
cmake ..

And I cannot find the symbol sha256_word defined anywhere?

OS: Windows 10 Professional version: 21H1
Blade version : 0.0.6

Run the following script,

var str_len = 1500
#str_len = 200
var file_id = file('foo')
file_id = file('bar')
# Loop for creating 'str' string
var str = ''
iter var idx = 0; idx < str_len; idx++ {
    str += '1'
}
echo 'End of iter loop'

Result: the last line is not executed because the loop that creates the string stops before the end and interrupts the script.

If you either uncomment line 2 # str_len = 200 (the string length is reduced to 200 characters) or comment line 4 file_id = file('bar') (file_id is no longer overwrited), End of iter loop is displayed as expected.

Blade Version

v0.0.83

Description

I have found a really interesting case.

I have a dictionary like this:

{0: /foo/bar, 1: foo, 2: bar, firstname: foo, wildcard: bar}

Now all of the following don't work:

echo mydict.contains("wildcard") # false
for key, value in request.params {
  echo '"${key}" = "${value}"'
}
# "0" = "/foo/bar"
# "1" = "foo"
# "2" = "bar"
# "firstname" = "foo"
# "wildcard

# Yes, the last one is not a mistake, it actually just prints "wildcard without closing it

So even though doing echo mydict shows the key is there, something is wrong with it, so I cannot retrieve the value.

This can be seen on dev branch on: https://github.com/BenStigsen/router/tree/dev
Going to localhost:3000/foo/bar will not show bar even though it's in the dictionary.

I don't have a shorter reproducible example than the one in my repo.

Specifically L19-L29 gets the route, then matches on the regex. If there's a match, then it sets req.params to the regex matches.
L45 replaces something like /route/* with the regex /route/(?P<wildcard>.*), so that the wildcard gets stored in the wildcard key, in the returned regex dictionary.

Hello. I am kind of curious, will there be a package manager for this programming language? Examples could be pip for Python, or Cargo for Rust. This could be a good step in making this language usable for a lot of people. If you want, I could add a PR or an entirely different repository for this. Although, I don't have a good name for the package manager or the packages.

It would be useful to expose parsing Blade code as a standard library module for the purposes of writing utilities, generating documentation and a language server, for example.

This will be implemented as built-in module markdown.

Socket doesn't work well on Windows

Due to how the socket constants such as AF_INET are defined in the socket.b library file, it does not account for the different values that may be encountered on the different platforms.

Expected behavior

The socket module constants should tally with their native value.

Prescribed solution

Bind the values from C into the _socket module and import them in the socket module for clear definition and script level documentation so that people reading the socket.b file can tell the values are declared.

Hello,

We want to create a programming language for professional, personal and utility needs. We want to base ourselves on your language, which we find very interesting in its simplicity and speed. Can we fork your project? Or take over the project for free?

Merging qi — the testing package originally available as a Nyssa package at mcfriend99/qi into Blade as a Nyssa feature that can be invoke with nyssa test.

Windows 10 21H1
Blade v0.0.6/MSVC

The following error handling examples failed (https://bladelang.com/tutorial/error-handling).
Nothing is displayed.

This task intends to replace the existing bladelang.com website with a new version that's completely built in Blade. Nyssa documentation and Getting Started link will also be effectively pointing to it as Nyssa documentation will now be hosted along with Blade.

See #153

Long time since I've been here, but I've been following the project closely.
One thing that I have not been a fan of, is the exception with echo not requiring braces.
It's inconsistent and I'm not quite sure I understand the purpose of it?

Currently comments are being made like so:

# Hello World

/* 
Hello
There
World 
*/

This to me does not make sense. Not only is this inconsistent with languages like JS, C, Python and a whole bunch of other languages. But it's also a bit harder to remember.
My proposal is to use // comment instead as it makes switching to Blade easier. It's easier to remember, not only because of other languages, but also because one character less is used.

If this isn't going to be changed to // that is fine, but I do at least propose some more consistency between single line and multiline comments. In JS, C and many more languages this is the / character, since it is used for both single-line and multiline. In Lua this is --, etc...

TL;DR

I'm raising a proposal to refocus Blade language and its continued development on built-in support and focus on Web, IoT and secure application development without needing to install any third-party package and without losing it's ability for general-purpose development.

Content

After multiple considerations, I begin to feel that while being a general-purpose language, Blade will benefit a lot more from crafting a niche for itself as a general-purpose batteries-included language with a focus on Web, IoT and secure application development where third-party packages are completely optional.

In order to achieve this, Blade will need to begin to provide tooling to support this goals. This will include at a bare minimum the following tools:

• Built-in testing framework.
• Built-in ORM support.
• Built-in support for more databases.
• Built-in support for media processing (Image, audio, video etc).
• Built-in templating engine.
• Built-in routing library.
• Built-in cryptographic library.
• A more advanced/robust HTTP server implementation (we'll need to go beyond basics and aspire to achieve built-in production grade http server in the http module with support for UDP).
• A more robust http client implementation in the http module.
• Built-in device integrations (such as support for COM/Ports, USB etc).
• Built-in mail library.
• Built-in package management library (it will encourage adoption for Blade).
• Built-in C extension builder/packager.

Just to mention a few.

Along with this proposal, I have proposed some major changes to the Blade distribution.

1. Merge Nyssa into Blade as the built-in package manager.
2. Merge qi into Blade as the built-in testing framework.
3. Merge wire into Blade as the built-in template engine.
4. Merge kite into Blade as the default C extension builder/packager.
5. Merge miniroute as the built-in router.
6. Merge mysql int Blade as the built-in MySQL database integration.

What does this mean for the next release.

This proposal is aimed to start taking effect at version 0.0.86. The next release should be unaffected by this to allow more time for bug-fixes and testing for the proposed mergers.

Who can vote?

Everybody.
