34
-
- Removed compiler hint about pattern matching a `Result(a, b)` when being used
35
-
where `a` is expected.
36
-
([Kieran O'Reilly](https://github.com/SoTeKie))
37
-
38
-
- Optimised code generated for record updates.
39
-
([yoshi](https://github.com/joshi-monster))
40
-
41
-
- The compiler now allows for record updates to change the generic type
42
-
parameters of the record:
43
-
44
-
```gleam
45
-
type Box(value) {
46
-
Box(password: String, value: value)
47
-
}
48
-
49
-
fn insert(box: Box(a), value: b) -> Box(b) {
50
-
Box(..box, value:)
51
-
}
52
-
```
53
-
54
-
([yoshi](https://github.com/joshi-monster))
55
-
56
-
- It is now allowed to write a block with no expressions. Like an empty function
57
-
body, an empty block is considered incomplete as if it contained a `todo`
58
-
expression.
59
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
60
-
61
-
- The shorthand names for the two targets, `erl` and `js` are now
62
-
deprecated in code such as `@target`.
63
-
([Surya Rose](https://github.com/GearsDatapacks))
64
-
65
-
- A custom panic message can now be specified when asserting a value with
66
-
`let assert`:
67
-
68
-
```gleam
69
-
let assert Ok(regex) = regex.compile("ab?c+") as "This regex is always valid"
70
-
```
71
-
72
-
([Surya Rose](https://github.com/GearsDatapacks))
73
-
74
-
- When targeting JavaScript the compiler now generates faster and smaller code
75
-
for `Int` values in bit array expressions and patterns by evaluating them at
76
-
compile time where possible.
77
-
([Richard Viney](https://github.com/richard-viney))
78
-
79
-
- Qualified records can now be used in clause guards.
80
-
([Surya Rose](https://github.com/GearsDatapacks))
81
-
82
-
- The compiler now allows deprecating specific custom type variants using the
83
-
`@deprecated` attribute:
84
-
85
-
```gleam
86
-
pub type HashAlgorithm {
87
-
@deprecated("Please upgrade to another algorithm")
88
-
Md5
89
-
Sha224
90
-
Sha512
91
-
}
92
-
93
-
pub fn hash_password(input: String) -> String {
94
-
hash(input:, algorithm: Md5) // Warning: Deprecated value used
95
-
}
96
-
```
97
-
98
-
([Iesha](https://github.com/wilbert-mad))
99
-
100
-
- On the JavaScript target, taking byte-aligned slices of bit arrays is now an
101
-
O(1) operation instead of O(N), significantly improving performance.
102
-
([Richard Viney](https://github.com/richard-viney))
103
-
104
-
- Better error message for when an existing type constructor is used as a value
105
-
constructor.
106
-
([Jiangda Wang](https://github.com/Frank-III))
107
-
108
-
- Print better error messages when shell commands used by compiler cannot be
109
-
found.

### Build tool
113
8
114
-
- Improved the error message you get when trying to add a package that doesn't
115
-
exist with `gleam add`.
116
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
117
-
118
-
- External files (such as `.mjs` and `.erl`) are now permitted in subdirectories
119
-
of `src/` and `test/`.
120
-
([PgBiel](https://github.com/PgBiel))
121
-
122
-
- `gleam publish` now requires more verbose confirmation for publishing Gleam
123
-
team packages and v0 packages.
124
-
([Louis Pilfold](https://github.com/lpil))
125
-
126
-
- `gleam publish` now warns when publishing packages that define multiple
127
-
top-level modules, as this can lead to namespace pollution and conflicts for
128
-
consumers.
129
-
([Aleksei Gurianov](https://github.com/guria))
130
-
131
-
- New projects now require `gleam_stdlib` v0.44.0.
132
-
([Louis Pilfold](https://github.com/lpil))
133
-
134
-
- `gleam remove` no longer requires a network connection.
135
-
([yoshi](https://github.com/joshi-monster))
136
-
137
-
- Commands that work with the Hex package manager API now create and store an
138
-
API key rather than creating a new one each time. This API key is encrypted
139
-
with a local password, reducing risk of your Hex password being compromised.
140
-
([Louis Pilfold](https://github.com/lpil))
141
-
142
-
- The build tool now sets the `REBAR_SKIP_PROJECT_PLUGINS` environment variable
143
-
when using rebar3 to compile Erlang dependencies. With future versions of
144
-
rebar3 this will cause it to skip project plugins, significantly reducing the
145
-
amount of code it'll need to download and compile, improving compile times.

### Language server
149
10
150
-
- The language server now provides type information when hovering over argument
151
-
labels.
152
-
([Surya Rose](https://github.com/GearsDatapacks))
153
-
154
-
- The language server now suggests a code action to desugar a use expression
155
-
into the equivalent function call. For example, this snippet of code:
156
-
157
-
```gleam
158
-
pub fn main() {
159
-
use profile <- result.try(fetch_profile(user))
160
-
render_welcome(user, profile)
161
-
}
162
-
```
163
-
164
-
Will be turned into:
165
-
166
-
```gleam
167
-
pub fn main() {
168
-
result.try(fetch_profile(user), fn(profile) {
169
-
render_welcome(user, profile)
170
-
})
171
-
}
172
-
```
173
-
174
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
175
-
176
-
- The language server now suggests a code action to turn a function call into
177
-
the equivalent use expression. For example, this snippet of code:
178
-
179
-
```gleam
180
-
pub fn main() {
181
-
result.try(fetch_profile(user) fn(profile) {
182
-
render_welcome(user, profile)
183
-
})
184
-
}
185
-
```
186
-
187
-
Will be turned into:
188
-
189
-
```gleam
190
-
pub fn main() {
191
-
use profile <- result.try(fetch_profile(user))
192
-
render_welcome(user, profile)
193
-
}
194
-
```
195
-
196
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
197
-
198
-
- The language server now provides correct information when hovering over
199
-
patterns in use expressions.
200
-
([Surya Rose](https://github.com/GearsDatapacks))
201
-
202
-
- The language server now suggests a code action to convert an inexhaustive
203
-
`let` assignment into a `case` expression:
204
-
205
-
```gleam
206
-
pub fn unwrap_result(result: Result(a, b)) -> a {
207
-
let Ok(inner) = result
208
-
inner
209
-
}
210
-
```
211
-
212
-
Becomes:
213
-
214
-
```gleam
215
-
pub fn unwrap_result(result: Result(a, b)) -> a {
216
-
let inner = case result {
217
-
Ok(inner) -> inner
218
-
Error(_) -> todo
219
-
}
220
-
inner
221
-
}
222
-
```
223
-
224
-
([Surya Rose](https://github.com/GearsDatapacks))
225
-
226
-
- The language server now provides an action to extract a value into a variable.
227
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
228
-
229
-
- The language server now suggests a code action to expand a function capture
230
-
into the equivalent anonymous function. For example, this snippet of code:
231
-
232
-
```gleam
233
-
pub fn main() {
234
-
list.map([1, 2, 3], int.add(_, 11))
235
-
}
236
-
```
237
-
238
-
Will be turned into:
239
-
240
-
```gleam
241
-
pub fn main() {
242
-
list.map([1, 2, 3], fn(value) { int.add(value, 11) })
243
-
}
244
-
```
245
-
246
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
247
-
248
-
- The language server now suggests a code action to generate a dynamic decoder
249
-
for a custom type. For example, this code:
250
-
251
-
```gleam
252
-
pub type Person {
253
-
Person(name: String, age: Int)
254
-
}
255
-
```
256
-
257
-
Will become:
258
-
259
-
```gleam
260
-
import gleam/dynamic/decode
261
-
262
-
pub type Person {
263
-
Person(name: String, age: Int)
264
-
}
265
-
266
-
fn person_decoder() -> decode.Decoder(Person) {
267
-
use name <- decode.field("name", decode.string)
268
-
use age <- decode.field("age", decode.int)
269
-
decode.success(Person(name:, age:))
270
-
}
271
-
```
272
-
273

### Formatter
276
12
277
-
- The formatter now adds a `todo` inside empty blocks.
278
-
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
279
-
280
-
- The formatter now formats lists the same in constants as in expressions.
281
-
([Jiangda Wang](https://github.com/Frank-III))
282
-
283
-
### Documentation
284
-
285
-
- Canonical links created for documentation pages if published on Hex.
286
-
Previously published documentation would need to be updated.
287
-
Resolves versioned pages to point to latest page for search engines.
288
-

### Build tool
117

118
+
- Improved the error message you get when trying to add a package that doesn't
119
+
exist with `gleam add`.
120
+
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
121
+
122
+
- External files (such as `.mjs` and `.erl`) are now permitted in subdirectories
123
+
of `src/` and `test/`.
124
+
([PgBiel](https://github.com/PgBiel))
125
+
126
+
- `gleam publish` now requires more verbose confirmation for publishing Gleam
127
+
team packages and v0 packages.
128
+
([Louis Pilfold](https://github.com/lpil))
129
+
130
+
- `gleam publish` now warns when publishing packages that define multiple
131
+
top-level modules, as this can lead to namespace pollution and conflicts for
132
+
consumers.
133
+
([Aleksei Gurianov](https://github.com/guria))
134

- New projects now require `gleam_stdlib` v0.44.0.
136
+
([Louis Pilfold](https://github.com/lpil))
137
+
138
+
- `gleam remove` no longer requires a network connection.
139
+
([yoshi](https://github.com/joshi-monster))
140
+
141
+
- Commands that work with the Hex package manager API now create and store an
142
+
API key rather than creating a new one each time. This API key is encrypted
143
+
with a local password, reducing risk of your Hex password being compromised.
144
+
([Louis Pilfold](https://github.com/lpil))
145
+
146
+
- The build tool now sets the `REBAR_SKIP_PROJECT_PLUGINS` environment variable
147
+
when using rebar3 to compile Erlang dependencies. With future versions of
148
+
rebar3 this will cause it to skip project plugins, significantly reducing the
149
+
amount of code it'll need to download and compile, improving compile times.

154
+
- The language server now provides type information when hovering over argument
155
+
labels.
156
+
([Surya Rose](https://github.com/GearsDatapacks))
157
+
158
+
- The language server now suggests a code action to desugar a use expression
159
+
into the equivalent function call. For example, this snippet of code:
160
+
161
+
```gleam
162
+
pub fn main() {
163
+
use profile <- result.try(fetch_profile(user))
164
+
render_welcome(user, profile)
165
+
}
166
+
```
167
+
168
+
Will be turned into:
169
+
170
+
```gleam
171
+
pub fn main() {
172
+
result.try(fetch_profile(user), fn(profile) {
173
+
render_welcome(user, profile)
174

})
175
+
}

([Giacomo Cavalieri](https://github.com/giacomocavalieri))
179
+
180
+
- The language server now suggests a code action to turn a function call into
181

the equivalent use expression. For example, this snippet of code:
182
+
183
+
```gleam

+
pub fn main() {
185

192
+
193
+
```gleam
194
+
pub fn main() {
195
+
use profile <- result.try(fetch_profile(user))

203
+
patterns in use expressions.
204
+
([Surya Rose](https://github.com/GearsDatapacks))
205
+
206
+
- The language server now suggests a code action to convert an inexhaustive
207
+
`let` assignment into a `case` expression:
208
+
209
+
```gleam
210
+
pub fn unwrap_result(result: Result(a, b)) -> a {
211
+
let Ok(inner) = result
212
+
inner
213
+
}
214
+
```
215
+
216
+
Becomes:
217
+
218
+
```gleam
219
+
pub fn unwrap_result(result: Result(a, b)) -> a {
220
+
let inner = case result {
221
+
Ok(inner) -> inner
222
+
Error(_) -> todo
223

}
224

- The language server now provides an action to extract a value into a variable.
231
+
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
232
+
233
+
- The language server now suggests a code action to expand a function capture
234
+
into the equivalent anonymous function. For example, this snippet of code:
235
+
236
+
```gleam
237
+
pub fn main() {
238
+
list.map([1, 2, 3], int.add(_, 11))
239
+
}
240
+
```
241
+
242
+
Will be turned into:
243
+
244
+
```gleam
245
+
pub fn main() {
246
+
list.map([1, 2, 3], fn(value) { int.add(value, 11) })
247
+
}
248
+
```
249
+
250
+
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
251
+
252
+
- The language server now suggests a code action to generate a dynamic decoder
253
+
for a custom type. For example, this code:
254
+
255
+
```gleam
256
+
pub type Person {
257
+
Person(name: String, age: Int)
258
+
}
259
+
```
260
+
261
+
Will become:
262
+
263
+
```gleam
264
+
import gleam/dynamic/decode
265
+
266
+
pub type Person {
267
+
Person(name: String, age: Int)
268
+
}
269
+
270
+
fn person_decoder() -> decode.Decoder(Person) {
271
+
use name <- decode.field("name", decode.string)
272
+
use age <- decode.field("age", decode.int)
273
+
decode.success(Person(name:, age:))
274
+
}

### Formatter
280
+
281
+
- The formatter now adds a `todo` inside empty blocks.
282
+
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
283
+
284
+
- The formatter now formats lists the same in constants as in expressions.

### Documentation
288
+
289
+
- Canonical links created for documentation pages if published on Hex.
290
+
Previously published documentation would need to be updated.
291
+
Resolves versioned pages to point to latest page for search engines.

+
315
+
- Fixed a bug where a `module.mjs` file would be overwritten by a `module.gleam`

319
+
- Modules depending on removed or renamed modules now get automatically
320
+
recompiled.
321
+
([Sakari Bergen](https://github.com/sbergen))
322
+
323
+
- The compiler now raises a warning for unused case expressions, code blocks and
324
+
pipelines that would be safe to remove.
325
+
([Giacomo Cavalieri](https://github.com/giacomocavalieri))
326
