FUNCTIONS

ln_s(%args) -> [status, msg, result, meta]

{en_US Create symlink}.

{en_US Fixed state: symlink exists and points to target.

Fixable state: symlink doesn't exist. }

This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function supports transactions.

Arguments ('*' denotes required arguments):

  • symlink => str

    {en_US Path to symlink}.

  • target => str

    {en_US Path to target}.

Special arguments:

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

rmsym(%args) -> [status, msg, result, meta]

{en_US Delete symlink}.

{en_US Will not delete non-symlinks.

Fixed state: path doesn't exist.

Fixable state: path exists, is a symlink, (and if target is defined, points to target). }

This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function supports transactions.

Arguments ('*' denotes required arguments):

  • path => str

  • target => str

    {en_US Only delete if existing symlink has this target}.

Special arguments:

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

{en_US Setup symlink (existence, target)}.

{en_US When should_exist=>1 (the default): On do, will create symlink which points to specified target. If symlink already exists but points to another target, it will be replaced with the correct symlink if replace_symlink option is true. If a file/dir already exists and replace_file/replace_dir option is true, it will be moved (trashed) first before the symlink is created. On undo, will delete symlink if it was created by this function, and restore the original symlink/file/dir if it was replaced during do.

When should_exist=>0: On do, will remove symlink if it exists (and replace_symlink is true). If replace_file/replace_dir is true, will also remove file/dir. On undo, will restore deleted symlink/file/dir. }

This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function supports transactions.

Arguments ('*' denotes required arguments):

  • create => bool (default: 1)

    {en_US Create if symlink doesn't exist}.

    {en_US If set to false, then setup will fail (412) if this condition is encountered. }

  • replace_dir => bool (default: 0)

    {en_US Replace if there is existing dir}.

    {en_US If set to false, then setup will fail (412) if this condition is encountered. }

  • replace_file => bool (default: 0)

    {en_US Replace if there is existing non-symlink file}.

    {en_US If set to false, then setup will fail (412) if this condition is encountered. }

  • replace_symlink => bool (default: 1)

    {en_US Replace previous symlink if it already exists but doesn't point to the wanted target}.

    {en_US If set to false, then setup will fail (412) if this condition is encountered. }

  • should_exist => bool (default: 1)

    {en_US Whether symlink should exist}.

  • symlink* => str

    {en_US Path to symlink}.

  • target => str

    {en_US Target path of symlink}.

    {en_US Required, unless should_exist => 0. }

Special arguments:

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
