+module: blockinfile
+short_description: Insert/update/remove a text block surrounded by marker lines
+version_added: '2.0'
+description:
+- This module will insert/update/remove a block of multi-line text surrounded by customizable marker lines.
+author:
+- Yaegashi Takeshi (@yaegashi)
+options:
+  path:
+    description:
+    - The file to modify.
+    - Before Ansible 2.3 this option was only usable as I(dest), I(destfile) and I(name).
+    type: path
+    required: yes
+    aliases: [ dest, destfile, name ]
+  state:
+    description:
+    - Whether the block should be there or not.
+    type: str
+    choices: [ absent, present ]
+    default: present
+  marker:
+    description:
+    - The marker line template.
+    - C({mark}) will be replaced with the values in C(marker_begin) (default="BEGIN") and C(marker_end) (default="END").
+    - Using a custom marker without the C({mark}) variable may result in the block being repeatedly inserted on subsequent playbook runs.
+    - Multi-line markers are not supported and will result in the block being repeatedly inserted on subsequent playbook runs.
+    - A newline is automatically appended by the module to C(marker_begin) and C(marker_end).
+    type: str
+    default: '# {mark} ANSIBLE MANAGED BLOCK'
+  block:
+    description:
+    - The text to insert inside the marker lines.
+    - If it is missing or an empty string, the block will be removed as if C(state) were specified to C(absent).
+    type: str
+    default: ''
+    aliases: [ content ]
+  insertafter:
+    description:
+    - If specified and no begin/ending C(marker) lines are found, the block will be inserted after the last match of specified regular expression.
+    - A special value is available; C(EOF) for inserting the block at the end of the file.
+    - If specified regular expression has no matches, C(EOF) will be used instead.
+    - The presence of the multiline flag (?m) in the regular expression controls whether the match is done line by line or with multiple lines.
+      This behaviour was added in ansible-core 2.14.
+    type: str
+    choices: [ EOF, '*regex*' ]
+    default: EOF
+  insertbefore:
+    description:
+    - If specified and no begin/ending C(marker) lines are found, the block will be inserted before the last match of specified regular expression.
+    - A special value is available; C(BOF) for inserting the block at the beginning of the file.
+    - If specified regular expression has no matches, the block will be inserted at the end of the file.
+    - The presence of the multiline flag (?m) in the regular expression controls whether the match is done line by line or with multiple lines.
+      This behaviour was added in ansible-core 2.14.
+    type: str
+    choices: [ BOF, '*regex*' ]
+  create:
+    description:
+    - Create a new file if it does not exist.
+    type: bool
+    default: no
+  backup:
+    description:
+    - Create a backup file including the timestamp information so you can
+      get the original file back if you somehow clobbered it incorrectly.
+    type: bool
+    default: no
+  marker_begin:
+    description:
+    - This will be inserted at C({mark}) in the opening ansible block marker.
+    type: str
+    default: BEGIN
+    version_added: '2.5'
+  marker_end:
+    required: false
+    description:
+    - This will be inserted at C({mark}) in the closing ansible block marker.
+    type: str
+    default: END
+    version_added: '2.5'
+notes:
+  - When using 'with_*' loops be aware that if you do not set a unique mark the block will be overwritten on each iteration.
+  - As of Ansible 2.3, the I(dest) option has been changed to I(path) as default, but I(dest) still works as well.
+  - Option I(follow) has been removed in Ansible 2.5, because this module modifies the contents of the file so I(follow=no) doesn't make sense.
+  - When more then one block should be handled in one file you must change the I(marker) per task.
