@ -102,9 +102,12 @@ The placeholder is evaluated as following:
The suggestion can have additional conditions to check. To specify the conditions, add a `#[...]` at the first line (just like derive macros in Rust). Available conditions:
- `executable`: Check if the argument can be found by `which`
- `cmd_contains`: Check if the last user input contains the argument
- `err_contains`: Check if the error of the command contains the argument
- `executable`: Check whether the argument can be found by `which`
- `cmd_contains`: Check whether the last user input contains the argument
- `err_contains`: Check whether the error of the command contains the argument
- `length`: Check whether the given command has the length of the argument
- `min_length`: Check whether the given command has at least the length of the argument
- `max_length`: Check whether the given command has at most the length of the argument
