FUNCTIONS
setup_text_fragment
Usage:
setup_text_fragment(%args) -> [$status_code, $reason, $payload, \%result_meta]
Insert/delete text fragment in a file (with undo support).
On do, will insert fragment to file (or delete, if "should_exist" is set
to false). On undo, will restore old file.
Unfixable state: file does not exist or not a regular file (directory
and symlink included).
Fixed state: file exists, fragment already exists and with the same
content (if "should_exist" is true) or fragment already does not exist
(if "should_exist" is false).
Fixable state: file exists, fragment doesn't exist or payload is not the
same (if "should_exist" is true) or fragment still exists (if
"should_exist" is false).
This function is not exported by default, but exportable.
This function is idempotent (repeated invocations with same arguments
has the same effect as single invocation). This function supports
transactions.
Arguments ('*' denotes required arguments):
* attrs => *hash*
Fragment attributes (only for inserting new fragment), passed to
Text::Fragment.
* comment_style => *bool*
Will be passed to Text::Fragment.
* good_pattern => *str*
Will be passed to Text::Fragment.
* id* => *str*
Fragment ID.
* label => *str*
Will be passed to Text::Fragment.
* path* => *str*
Path to file.
* payload* => *str*
Fragment content.
* replace_pattern => *str*
Will be passed to Text::Fragment.
* should_exist => *bool* (default: 1)
Whether fragment should exist.
* top_style => *bool*
Will be passed to Text::Fragment.
Special arguments:
* -tx_action => *str*
For more information on transaction, see L<Rinci::Transaction>.
* -tx_action_id => *str*
For more information on transaction, see L<Rinci::Transaction>.
* -tx_recovery => *str*
For more information on transaction, see L<Rinci::Transaction>.
* -tx_rollback => *str*
For more information on transaction, see L<Rinci::Transaction>.
* -tx_v => *str*
For more information on transaction, see L<Rinci::Transaction>.
Returns an enveloped result (an array).
First element ($status_code) is an integer containing HTTP-like status
code (200 means OK, 4xx caller error, 5xx function error). Second
element ($reason) is a string containing error message, or something
like "OK" if status is 200. Third element ($payload) is the actual
result, but usually not present when enveloped result is an error
response ($status_code is not 2xx). Fourth element (%result_meta) is
called result metadata and is optional, a hash that contains extra
information, much like how HTTP response headers provide additional
metadata.
Return value: (any)
