AutoformatCommonRule
An interface for the common structure of autoformat rules, regardless of their mode.
Attributes
- For
mode: 'block'
: lookup for the end match(es) before the cursor. - For
mode: 'text'
: lookup for the end match(es) before the cursor. Ifformat
is an array, also lookup for the start match(es). - For
mode: 'mark'
: lookup for the start and end matches. - Note:
'_*'
,['_*']
and{ start: '_*', end: '*_' }
are equivalent. MatchRange
:- Default:
false
AutoformatQueryOptions
extendsOmit<AutoformatCommonRule, 'query'>
:
The rule applies when the trigger and the text just before the cursor matches.
Triggering character to autoformat.
If true, insert the triggering character after autoformatting.
A query function to allow autoformat.
AutoformatBlockRule
An interface for autoformat rules for block mode.
Attributes
- Text: insert text.
- Block: set block type or custom format.
- Mark: insert mark(s) between matches.
- For
mode: 'block'
: set block type. Ifformat
is defined, this field is ignored. - For
mode: 'mark'
: Mark(s) to add. - Default:
true
- Default:
false
A pattern to match for the autoformat rule to apply.
If true, the trigger should be at block start to allow autoformatting.
If true, allow to autoformat even if there is a block of the same type above the selected block.
Function called just before format
. Generally used to reset the selected
block.
Custom formatting function.
AutoformatMarkRule
An interface for autoformat rules for mark mode.
Attributes
The mode is 'mark'.
Mark(s) to add.
If false, do not format when the string can be trimmed.
AutoformatTextRule
An interface for autoformat rules for text mode.
Parameters
The mode is 'text'.
A pattern to match for the autoformat rule to apply.
The matched text is replaced by that string, the matched texts are replaced by these strings, or a function called when there is a match.
Customizable and extensible.
