backward

searchContextBackward

Arguments

:: (HasCallStack, MonadIO m, IsSearchContext a)

=> a

search: a SearchContext.

-> TextIter

iter: start of search.

-> m (Bool, TextIter, TextIter)

Returns: whether a match was found.

Deprecated: (Since version 3.22)Use searchContextBackward2 instead.

Synchronous backward search. It is recommended to use the asynchronous functions instead, to not block the user interface. However, if you are sure that the buffer is small, this function is more convenient to use.

Since: 3.10

backward2

searchContextBackward2

Arguments

:: (HasCallStack, MonadIO m, IsSearchContext a)

=> a

search: a SearchContext.

-> TextIter

iter: start of search.

-> m (Bool, TextIter, TextIter, Bool)

Returns: whether a match was found.

Synchronous backward search. It is recommended to use the asynchronous functions instead, to not block the user interface. However, if you are sure that the buffer is small, this function is more convenient to use.

The difference with searchContextBackward is that the hasWrappedAround out parameter has been added for convenience.

If the SearchSettings:wrap-around property is False, this function doesn't try to wrap around.

The hasWrappedAround out parameter is set independently of whether a match is found. So if this function returns False, hasWrappedAround will have the same value as the SearchSettings:wrap-around property.

Since: 3.22

backwardAsync

searchContextBackwardAsync

Arguments

:: (HasCallStack, MonadIO m, IsSearchContext a, IsCancellable b)

=> a

search: a SearchContext.

-> TextIter

iter: start of search.

-> Maybe b

-> Maybe AsyncReadyCallback

callback: a AsyncReadyCallback to call when the operation is finished.

-> m ()

The asynchronous version of searchContextBackward2.

See the documentation of searchContextBackward2 for more details.

See the AsyncResult documentation to know how to use this function.

If the operation is cancelled, the callback will only be called if cancellable was not Nothing. searchContextBackwardAsync takes ownership of cancellable, so you can unref it after calling this function.

Gets the position of a search occurrence. If the buffer is not already fully scanned, the position may be unknown, and -1 is returned. If 0 is returned, it means that this part of the buffer has already been scanned, and that matchStart and matchEnd don't delimit an occurrence.

Since: 3.10

Free the return value with errorFree.

Since: 3.10

getSettings

searchContextGetSettings

Arguments

:: (HasCallStack, MonadIO m, IsSearchContext a)

buffer: a Buffer.

-> Maybe b

settings: a SearchSettings, or Nothing.

-> m SearchContext

Arguments

:: (HasCallStack, MonadIO m, IsSearchContext a)

=> a

search: a SearchContext.

-> TextIter

matchStart: the start of the match to replace.

matchEnd: the end of the match to replace.

-> Text

replace: the replacement text.

-> Int32

replaceLength: the length of replace in bytes, or -1.

-> m ()

(Can throw GError)

Deprecated: (Since version 3.22)Use searchContextReplace2 instead.

Replaces a search match by another text. If matchStart and matchEnd doesn't correspond to a search match, False is returned.

For a regular expression replacement, you can check if replace is valid by calling regexCheckReplacement. The replace text can contain backreferences; read the regexReplace documentation for more details.

Since: 3.10

-> m ()

(Can throw GError)

Replaces a search match by another text. If matchStart and matchEnd doesn't correspond to a search match, False is returned.

Unlike with searchContextReplace, the matchStart and matchEnd iters are revalidated to point to the replacement text boundaries.

For a regular expression replacement, you can check if replace is valid by calling regexCheckReplacement. The replace text can contain backreferences; read the regexReplace documentation for more details.

Since: 3.22

replaceAll

searchContextReplaceAll

Arguments

:: (HasCallStack, MonadIO m, IsSearchContext a)

-> m Word32

Returns: the number of replaced matches. (Can throw GError)

Replaces all search matches by another text. It is a synchronous function, so it can block the user interface.

For a regular expression replacement, you can check if replace is valid by calling regexCheckReplacement. The replace text can contain backreferences; read the regexReplace documentation for more details.

Since: 3.10

=> a

search: a SearchContext.

-> Maybe b

settings: the new SearchSettings, or Nothing.

-> m ()

Deprecated: (Since version 3.24)The SearchContext:settings property will become aconstruct-only property in a future version. Create a newtSearchContext instead, or change the SearchSettingsproperties. When the SearchContext:settings property will becomeconstruct-only, it will be possible to simplify some code that needed tolisten to the notify[settings](#g:signal:settings) signal.

Associate a SearchSettings with the search context. If settings is Nothing, a new one will be created.

The search context holds a reference to settings.
