Describe the bug
An error throws when passing array to a function have a slice input.
error: function 'foo' expected input argument of type '[]i32'; '[10]i32' was provided

To Reproduce
Execute the test source below:

package main

func foo(a []i32) {
        printf("%d", len(a))
}

func main() {
        var a [10]i32
        foo(a)
}

Expected behavior
Should accept passing array to a function have slice argument

• CX Version 0.7.0

@corpusc commented on Jul 26

Describe the bug
The "continue" keyword should just bypass the remainder of the current iteration of the current loop, and go to the next iteration of the current loop. But in CX it completely EXITs the whole loop (like "break" would do), and even exits out of an OUTER loop (but stops there, unlike the previous "break" Issue report).

To Reproduce

1. Use this code:

package main

func main() {
for h := 0; h < 3; h++ {
printf("h: %d \n", h)

for i := 0; i < 3; i++ {
		printf("  i: %d \n", i)
		
		for j := 0; j < 3; j++ {
			if j > 0 {
				continue
			}		
					
			printf("    j: %d \n", j)
		}
		
		str.print("out of j loop")
	}
	
	str.print("out of i loop")
}

str.print("out of h loop")
}

2. See output section below:

Expected behavior
"j: 0" is, indeed, the only feedback we should see for the j loop,
but the i loop should show values 1-3,
and all 3 of the "out of _ loop" prints should be shown.

Output
h: 0
i: 0
j: 0
h: 1
i: 0
j: 0
h: 2
i: 0
j: 0
out of h loop

Describe
...and it will give different numbers, affected by the values of a struct field.

To Reproduce

1. use this code:

package main

type TextInfo struct {
Text str
Font str
Size f32
Wid f32 // caches string measure queries
Hei f32
}

func main() {
var texts []TextInfo
texts = []TextInfo{TextInfo{Text:"hmm"}}
printf("len %d \n", len(texts))
}

2. Now add an extra 'm' character to the "Text" field, and watch CX report a different size

...and gives no file/line info.
This is with a single field, my next Issue report shows a different kind of error when you have 3 fields. At least you get some file/line info in THAT case (but not THIS Issue's case).

To Reproduce
Steps to reproduce the behavior:

1. Use code:

package main

type Color3 struct {
R f32
}

func main() {
var nums [3]i32 = [3]i32{ 1, 2, 3 }
var colors [1]Color3 = [1]Color3{Color3{R: 1.0}}
}

If you comment out the "var colors" line, you see it works fine with i32s

I think a function such as str.to_scii : str -> []byte and str.to_unicode : str -> []byte, as well as str.from_ascii : []byte -> str and str.from_unicode : []byte -> str would be very useful.

As far as I know the only way to convert ASCII strings into ASCII codes is using a lookup table, and isn't possible for Unicode strings as far as I know.

	i32.print(i[0][0][0])
	i32.print(i[0][0][1])
	i32.print(i[0][0][2])
}

2. Run the source file with cx -r test.cx
3. Run the CX meta-command :dp to display the AST.
4. Notice that the types associated to the temporary variables created by the CX parser are not correct.

Expected behavior
The parser should create the temporary variables involved in the creation of an slice literal with the correct types (which include the dimensions declared for i).

The following program does not work. If you uncomment the line marked "This gives a compilation error", you will get a compilation error. :)

package main

type Foo struct {
x i32
}

func (f *Foo) Print() {
// This gives a compilation error:
//str.print("X: " + i32.str((*f).x))

// This works
str.print("X: ")
str.print(i32.str((*f).x))

}

func main() {
var foo Foo
foo.x = 3

foo.Print()

The marked line should work too

when using a common dir with a relative path, you have to move the "." argument out of the 1st argument slot (i did not try "." in the 3rd or higher numbered slots).
making an argument for every file in the CWDir instead of using "." will also work, FWIW.

To Reproduce

1. Go into a working project dir
2. (one that works properly, when run with "cx .")
3. Make a "..\2DFWork" dir
4. Move 1 of your files there
5. Run it with "cx . ..\2DFWork\app.cx" <--- ERROR
6. Run it with "cx ..\2DFWork\app.cx ." <--- IT WORKS

ERROR
"error: draw.cx:57, CX_RUNTIME_ERROR, runtime error: integer divide by zero"

and there was no cases of "/" or "div" in draw.cx.
i believe in my experiments it also reported some OTHER erroneous message.
but the same source code works fine if "." isn't the 1st argument
(however i did not try it in 3rd or higher slot).

CX Version 0.0.7, commit: f999780

@0pcom commented on Jul 19

CX version 0.7.0
This version of cx includes (I think) OpenGL version 2.1

A reference of the parameters for gl.Begin() & gl.End() can be found here

Here is the OpenGL Programming Guide for version 2.1 from which I am attempting to run some examples.

For additional reference; the following functions as desired:

gl.Init()
gl.Enable(gl.BLEND)
gl.BlendFunc(gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA)

Other parameters from the list which at least appear to exist:

gl.Enable(gl.COLOR_SUM)

gl.Enable(gl.CULL_FACE)

gl.Enable(gl.DEPTH_TEST)

gl.Enable(gl.DITHER)

gl.Enable(gl.LIGHTING)

gl.Enable(gl.LINE_SMOOTH)

gl.Enable(gl.POLYGON_SMOOTH)

gl.Enable(gl.SCISSOR_TEST)

gl.Enable(gl.STENCIL_TEST)

gl.Enable(gl.TEXTURE_2D)

However some other parameters give panic: struct not found in package 'gl'
I can't say for certain that the absence of these parameters is a bug, incompleteness, or if it's the documentation for this which is missing.

@ReewassSquared commented on Jun 9

This is expanding on issue #306.

escape codes for single and double quotes do not function as intended. Single quotes throws an error "unexpected single quote".

Not sure why the error would be happening for single quotes as well.

Describe the bug
Can't declare and inline initialize multiple variable from return values of a function call.

To Reproduce

package main

func foo()(i i32, f f32) {
	i = 5
	f = 1.0
}

func main()(){
	i, f := foo()

	test(i, 5, "")
	test(f, 1.0, "")
}

Expected behavior
No compilation error and test pass.

Desktop:

I am using the latest version of CX compiled from source with make build-full for opengl support

Describe the bug

In testing the whacky stack game I noticed an error which occurs with cx 0.7.1
This error is not present in previous cx versions; and the game works successfully with cx 0.7.0.

error: menu.cx:63, CX_RUNTIME_SLICE_INDEX_OUT_OF_RANGE, 9

Here is the link to the menu.cx file which the error is referring to

The error message is pointing to the last line here:

func makeMenuItem(menuId i32, size f32, text str) {
 	var mIt MenuItem 
 	mIt = MenuItem{ Size: size, Text: text }
 	Items[menuId] = append(
	Items[menuId], mIt)
}

To Reproduce

Compile CX 0.7.1 with opengl
from the skycoin/cx folder:
make build-full
clone the cx games repo

git clone https://github.com/skycoin/cx-games
cd cx-games/whacky-stack

run the game with cx 0.7.1 and 0.7.0
cx .
Expected behavior
error should not be there

@corpusc commented on Jun 4

Describe the bug

although this is a bottom priority thing, and it is fairly obvious what the problem is in my example code,... when you have a long/complex line/expression, it can take awhile to figure out what the problem is, when the error refers to characters that may not be present in the line/expression. which is what happened to me. :) and CX code is heavy with parentheses pairs with all the longhand expressions currently needed (for reliability).

To Reproduce

1. use the following code:
   package main

var sl []i32 = []i32{1,2,3}

func main () {
printf("len: %d", len(sl)
}

2. now delete the the right curly brace from line 3, for the same error message (pointing to different line).

3. now reduce line 6 to just "printf(" and you get a DIFFERENT wrong error message:
   "unexpected RBRACE"

Expected behavior

i would like the error to mention that a matching right parenthesis (or curly brace) is needed.

To Reproduce

1. Use code:

}

func main() {
var colors []Color3 = []Color3{ Color3{R: 1.0, G: 1.0, B: 1.0} }
i32.print(len(colors))
}

Observe error, then move the "var colors" line OUTSIDE of func, to see it run with no error. But notice the slice remains empty.
Expected behavior
To work both inside and outside of funcs.

Description

This could be at the very bottom of the priority list, as far as importance?
However it seems like it could be any easy side-fix when #452 gets fixed.

When I started making Issue #452, I tried making a code sample that was as simple as possible.
When you run this, every single print gets executed and shown:

package main

func main() {
if true {
if true {
if true {
break
printf("after break \n")
}

		str.print("hm")
	}
	
	str.print("hmm")
}

str.print("hmmm")
}

This got me curious about the break keyword, since I believe I've only tried it within
for loops. When looking at C# documentation, it seems it was only designed to be used within for loops and switch blocks. I assume it's probably the same for most C-like languages, so this sample apparently works fine, except for a lack of warning.

Expected behavior

CX should point to the file and line # where any incorrectly used "break" keyword is, and warn that it should only be used in the cases that CX expects.

Is your feature request related to a problem? Please describe.
It's not really a problem, but could be easier to track which cx binary version i use while debugging and testing

Describe the solution you'd like
when pressing cx -v you get back the version number like that:

CX version 0.7.1
Something like this would be nice:
For self compiled:

CX version 0.7.1
Selfbuild - BuildDate - BuildTime

Or for offical binary releases

CX version 0.7.1
Official - ReleaseDate

Desktop:

• OS: Linux
• CX Version 0.0.7, commit: f999780

@0pcom commented on Aug 9

Describe the bug

A cx program is defined which contains reference to functions with the same name from imported packages:

package main


import "foo"
import "bar"
import "xyzzy"

func main () {
xyzzy.testprint()
}

package foo

func test1 () {
str.print("Hello World!")
}

package bar

func test1 () {
str.print("Goodbye World!")
}

package xyzzy
import "main"

func testprint () {
main.test1()
}

The result of this program depends on the order the packages are imported

This is non-desireable or ambiguous behavior

To Reproduce
run the above program

Expected behavior
The program should probably display an error in the case that a func (rather, a pointer to a func name) is redefined by a subsequently imported package.

In lieu of that, It might be better if it was required to directly reference a package function, rather than just referencing main or another package which has already imported the requisite packages.

Desktop

• OS: Linux
• CX Version 0.7.1

Additional context

This behavior is different for vars than funcs

package main

import "bar"
import "foo"
import "xyzzy"

func main () {
xyzzy.testprint()
}

package foo
var string1 str = "Hello World!"

package bar
var string1 str = "Goodbye World!"

package xyzzy
import "main"

func testprint () {
str.print(sprintf("String 1: %s", main.string1))
}

when run gives:
panic: struct 'string1' not found in package 'main'

it appears while vars must be directly referenced, funcs can be referenced by proxy (i.e. referencing a package which has imported a package containing the func)

@corpusc commented on Jun 21

Description
Strangely enough, simply rearranging the same code can fix this example, so it compiles.

To Reproduce
Steps to reproduce the behavior:

1. use following code:
   package main

func main() {
foo()
bar()
}

func foo() {
if cat() {
for i := 0; i < 4; i++ {
}

if cat() {
}

}

if cat() {
}
}

func bar() {
}

func cat() (b bool) {
}

...and you will get the panic.

2. Simply MOVE the "if cat() {}" from the bottom of foo() into empty func bar(). FIXED!
3. BONUS weirdness & hopefully a hint....Now undo that change, so bar() is empty again.
4. Now DELETE the for loop. FIXED! Even tho it's a legit for loop by itself

Expected behavior
I certainly wouldn't expect for the EXACT same code and flow to cause errors unless i break it up into more funcs than I actually wanted.
My original code was WAY more complex, but I was able to give you a stripped to the bone, thin skeleton, that still exhibited the same strangeness.

Describe the bug

When the following code is run, nothing is printed.
It doesn't like anything inside the parentheses either.

To Reproduce

package main
import "os"

func main () {
  var wd str
  wd = os.GetWorkingDirectory()
str.print(wd)
}

Expected behavior
I assume it should be putting something into var wd and print it back to the screen.

System:

• OS: Archlinux
• 0.7beta

Additional Context

The other os functions don't seem to work correctly either;

os.Open()
os.Close()

else their documentation is missing something.

@asahi3g commented on Jul 3

To Reproduce

package main

func main()() {
	printf("%s\n", -1)
	panic(true, false, "must not compile")
}

Expected behavior
Compilation error eg golang:
Printf format %s has arg -1 of wrong type int
Ideally this should be done at compile time when the format string is a literal.

Describe the bug
Considering the following code:

var i [3][2]i32

var a [2]i32
var b [2]i32
var c [2]i32

a = [2]i32{1,2}
b = [2]i32{30,40}
c = [2]i32{500,600}

i = [3][2]i32{a, b, c}

which generates the following (partial) abstract syntax tree (AST):

17.- Expression: *tmp_6[0] [2]i32 = identity(a [2]i32)
18.- Expression: *tmp_6[1] [2]i32 = identity(b [2]i32)
19.- Expression: *tmp_6[2] [2]i32 = identity(c [2]i32)
20.- Expression: i [3][2]i32 = identity(*tmp_6 [2]i32)

*tmp_6 (a temporary variable created by the parser) has the correct indexing, but the parser is not declaring it with the correct type. It is ignoring the indexes of i (instead of creating a matrix is is creating a vector).

To Reproduce
In order to reproduce this problem, CX needs to include the changes presented in PR #479 to see the same AST. If this PR has not been merged, test the code below by git checkouting the branch used in that PR. Steps to reproduce the behavior:

1. Type in the following code in a test.cx file:

package main

func main() {
	var i [3][2]i32

	var a [2]i32
	var b [2]i32
	var c [2]i32
	a = [2]i32{1,2}
	b = [2]i32{30,40}
	c = [2]i32{500,600}

	i = [3][2]i32{
		a, b, c}
}

2. Run the source file with cx -r test.cx
3. Run the CX meta-command :dp to display the AST.

Expected behavior
The parser should create the temporary variables involved in the creation of an array literal with the correct types (which include the dimensions declared for i).

Desktop (please complete the following information):

• OS: Linux, Debian.
• CX from branch in PR #479 .

Describe the bug
Variable declared at global scope can be redeclared at local scope without compilation error.

To Reproduce

package main
var i i32 = 55
func main()() {
	var i i32 = 44
	panic(true, false, "must not compile")
}

Expected behavior
Compilation error stating i is redeclared

Desktop (please complete the following information):

• OS: linux
• CX Version 0.6.2 commit 4ba0d2d

Additional context
Add any other context about the problem here.

@asahi3g commented on Jul 3

To Reproduce

package main

func foo()(out bool) {
	out = true
}

func main()() {
	var b bool = !foo()
	test(b, false, "")
}

Expected behavior
No compilation error and test pass
