30 Apr 2023
The following changes may break compilation of existing code or change behavior at runtime:
-
json
: enums are serialized as strings by default,[json_as_number]
attribute can be used for the old behavior.If you are serializing enums to JSON in your application, then you will need to add the
[json_as_number]
attribute to keep the old behavior! -
Variable shadowing has been completely banned (previously variable names could conflict with module names).
- vweb now supports live page reloading. The web app is instantly updated in the browser (no need to refresh the page) every time a .v or a .html file is changed.
- vweb is now significantly faster and more stable under load, due to a new multithreaded worker pool, which is much more efficient at spreading the workload among all threads equally.
- vweb now supports middleware.
- vweb now supports controllers. It's now possible to have multiple app structs to better separate logic.
- vweb now supports overridable
.not_found()
method for custom 404 pages in vweb. - vweb now uses database pool.
- Fixed multipart form parsing in vweb.
- A new pure WASM backend, based on binaryen, a WASM
builtin
module, and a pure V WASM serialization library. - Lots of fixes and new features in the native backend, including making codegen logic platform independent.
- Now code generated by the С backend, can be compiled by a C++20 compiler.
- C backend does not generate unused interface functions now.
v share file.v
for sharing code via the playground.v up
speed up for when it hasn't been run for a long time (vc/ bootstrapping has been optimized).v init
no longer overwrites existingsrc/main.v
.v self
now uses a faster TCC backend on macOS (Intel/Apple Silicon), just like on Windows/Linux.- A new command line flag
-e
for running short V programs on command line:v -e "println(2+5)"
( works just like in Perl). - A new
-ldflags
option, in addition to-cflags
. Works just like LDFLAGS in C.
- All ORM queries now return
![]
(Result
of an array). This allows handling/propagating DB errors and simplifies working with ORM (one way). - Many ORM improvements: type checks for
limit/offset/order by/where
; support of reference objects ininsert
; struct fields can be used withlimit/offset
;Connection
interface. - ORM now supports the
like
operator:users := sql db { select from User where name like 'Bob%' }
- A new
-d trace_orm
option to see all SQL queries generated and used by V ORM and-d trace_pg_error
to trace PG errors.
- Added new
termios
module. net.ssl
: types using ssl contexts can now be converted to strings via.str()
/printed viaprintln()
.v.reflection
: added type symbol info metadata.crypto
andmath
modules have been updated to useResult
instead ofOption
.datatypes.LinkedList[map]
now works correctly.urllib.Values.get()
now returns an Option.strconv
:v_printf()
was made private,v_sprintf()
was deprecated. String interpolation should be used instead.net.http
: mime types have been updated to include all official types.gg
:create_image()
now returns!Image
instead ofImage
, allowing to handle errors.sokol
: errors during image creation no longer result in a panic, but can be handled by the programmer.sokol
: macOS apps can now be quit using Cmd+Q.os.hostname()
andos.loginname()
now returnResult
.strconv.atoi
optimizations.println()
now supports arrays with recursive references.termux
: support for cross-compilation from termux to other platforms.readline
module now works much better on macOS: key navigation, history, etc (now on par with Linux).os
: fixed a memleak ingetline()
.os.Process
now has acreate_no_window
option (Windows only).os.Process
now has aset_work_folder()
method to set the initial working folder of the new child process.
Final steps in making the Option type a first class type:
- If guards now work with struct fields which are
Option
functions. Such fields can now also be assigned to other fields/variables. - Option receivers can no longer have methods.
none
can now be cast to allOption
types, including aliases.- Option references are now supported:
?&Type
. - Arrays of
Option
s are now allowed. - Allow
foo := Foo{}
, whenFoo
has an Option field, that is a struct, that has a[required]
tag on its fields.
- Compile-time interface fields evaluation.
- Compile-time enum evaluation:
$for item in MyEnum.fields { println(item.value) println(item.name) }
- Added
$option
as a compile-time reflection type representing an any Option type. - All special compile-time reflection types are now lowercase (
$int
,$enum
,$option
, etc).
- Enums can no longer be initialized like structs.
- Capture variables can no longer shadow anonymous function params.
- Mixing multi-return results with other types in return statements is no longer allowed.
- Assigning anonymous structs to named structs is no longer allowed.
[required]
fields are now checked for embedded structs.- Fixed a bug with closures with fixed array variables.
- Builtin methods
first/last/repeat
can now be used in custom user types (previously they only worked in builtin arrays). - Generic struct initialization no longer needs explicit types to be provided:
struct Foo[T, U] { a T b U } foo := Foo{ a: 2 b: 'x' } println(foo)
- unsafe: dereferencing nil references is no longer allowed in the following case:
a := unsafe { nil } println(*a)
- Added basic QNX support.
- Lots of documentation/readme improvements.
- Lots of playground improvements: play.vlang.io, including a really cool feature: "Show generated C code".
- A new
[spawn_stack: 131072]
function attribute for controlling the max size of the stack of the spawned threads. - Channel pop now works with an
or
block:ch := <-self.item or { return none }
it
has been renamed toindex
in array inits.- "Is V still fast?" web-page has been sped up by splitting the result table into multiple years.
- GitHub Copilot summaries in PRs.
30 Jan 2023
- String interpolation simplified to just '${name}', enforced by vfmt, and updated in the entire code base.
go foo()
has been replaced withspawn foo()
(launches an OS thread,go
will be used for upcoming coroutines instead).- vfmt now supports
// vfmt off
and// vfmt on
for turning off the formatting locally for short snippets of code. Useful for keeping your carefully arranged matrices intact. - Match branch range expressions with consts:
match x { const1...const2 {} }
- Hot code reloading via
[live]
is now supported in imported modules, not just the main module. - Syntax sugar for map inits without needing explicit casts for interfaces:
all.children := { "abc": rect, "def": ui.rectangle()}
. $embed_file()
fixes, including variable args support.none
fixes: no longer allowed to be used as a separate type,dump()
support, not allowed insideunsafe
.- Const functions:
const y = term.yellow
, thenprintln(y('abc'))
. - Builtin type names can no longer be used as identifiers.
- Generic
typeof[T]()
,sizeof[T]()
,isreftype[T]()
functions. - Deprecated
-error-limit
in favour of the documented-message-limit
option. - Maps now support aliased keys.
- Operator overloading now works with reference types.
- Generic struct inits with nested generic structs and generic optional types are now allowed.
- During array creation,
len:
is required when using default values for the array. - Optimized one byte
[]u8
arrays creation. - Recursive aliasing is no longer allowed (e.g.
type Alias = map[string]Alias
).
[]
is now used for generics instead of<>
.- Accessing a pointer map value requires an
or {}
block outsideunsafe
.
- Lots of fixes in the type checker.
- Int signedness mismatch is now checked:
cannot use literal signed integer as u8
.
math.vec
module for generic vector math including 2D, 3D, and 4D vector operations.- Builtin stb_image.h used by gg has been updated to the latest v2.28.
- All of vlib has been updated to use separate Option/Result types.
- To avoid confusion, all references in the code and documentation to
Optional
have been replaced withOption
. gg.Context
pipeline has more effects, including theadditive
effect.- Much cleaner eof checks in
os
