g:ale_echo_msg_format *g:ale_echo_msg_format*
Type: |String|
Default: `'%s'`
Default: `'%code: %%s'`
This variable defines a message format for echoed messages. The following
sequences of characters will be replaced.
`%s` - will be replaced with the text for the problem
`%linter%` - will be replaced with the name of the linter
`%severity%` - will be replaced withe severity of the problem
`%s` - replaced with the text for the problem
`%...code...% `- replaced with the error code
`%linter%` - replaced with the name of the linter
`%severity%` - replaced withe severity of the problem
The strings for `%severity%` can be configured with the following options.
|g:ale_echo_msg_error_str| - Defaults to `'Error'`
|g:ale_echo_msg_warning_str| - Defaults to `'Warning'`
`%code%` is replaced with the error code, and replaced with an empty string
when there is no error code. Any extra characters between the percent signs
will be printed when an error code is present. For example, a message like
`(error code): message` will be printed for `'%(code): %%s'` and simply the
message will be printed when there is no code.
|g:ale_echo_cursor| needs to be set to 1 for messages to be displayed.
