Previously the command-line arguments for `nix profile remove` and `nix profile upgrade` matched the package entries using regular expression.
|
||
|
|
For instance:
|
||
|
|
|
||
|
|
```
|
||
|
|
nix profile remove '.*vim.*'
|
||
|
|
```
|
||
|
|
|
||
|
|
This would remove all packages that contain `vim` in their name.
|
||
|
|
|
||
|
|
In most cases, only singular package names were used to remove and upgrade packages. Mixing this with regular expressions sometimes lead to unintended behavior. For instance, `python3.1` could match `python311`.
|
||
|
|
|
||
|
|
To avoid unintended behavior, the arguments are now only matching exact names.
|
||
|
|
|
||
|
|
Matching using regular expressions is still possible by using the new `--regex` flag:
|
||
|
|
|
||
|
|
```
|
||
|
|
nix profile remove --regex '.*vim.*'
|
||
|
|
```
|
||
|
|
|
||
|
|
One of the most useful cases for using regular expressions was to upgrade all packages. This was previously accomplished by:
|
||
|
|
|
||
|
|
```
|
||
|
|
nix profile upgrade '.*'
|
||
|
|
```
|
||
|
|
|
||
|
|
With the introduction of the `--all` flag, this now becomes more straightforward:
|
||
|
|
|
||
|
|
```
|
||
|
|
nix profile upgrade --all
|
||
|
|
```
