Robotframework-tidy

Fixes
- ``*** Tasks ***`` will no longer be renamed to ``*** Test Cases ***`` by NormalizeSectionHeaderName ([279](https://github.com/MarketSquare/robotframework-tidy/issues/279)).

Transformers
- Updated `NormalizeNewLines` to separate sections by two empty lines (instead of one). It's effort of normalizing
Robocop output (which suggest to use 2 empty lines) and Robotidy (which previously transformed with 1 empty line) ([536](https://github.com/MarketSquare/robotframework-robocop/issues/536)).

Previously:

*** Settings ***
Force Tags tag

*** Test Cases ***
Test
No Operation


Now:

*** Settings ***
Force Tags tag


*** Test Cases ***
Test
No Operation


Other
- Add missing packaging dependency ([275](https://github.com/MarketSquare/robotframework-tidy/issues/275))

Transformers
- New `ReplaceReturns` transformer that replaces return statements (such as `[Return]` setting or `Return From Keyword` keyword) with `RETURN` statement ([231](https://github.com/MarketSquare/robotframework-tidy/issues/231))
- New `ReplaceBreakContinue` transformer that replaces `Continue For Loop` and `Exit For Loop` keyword variants with CONTINUE and BREAK statements ([241](https://github.com/MarketSquare/robotframework-tidy/issues/241))
- New `InlineIf` transformer that replaces IF blocks with inline IF ([230](https://github.com/MarketSquare/robotframework-tidy/issues/230))
- Add `min_width` parameter to `AlignSettingsSection` transformer. It allows to set minimal width of data column ([242](https://github.com/MarketSquare/robotframework-tidy/issues/242))
- Add `min_width` parameter to `AlignVariablesSection` transformer. It allows to set minimal width of data column ([242](https://github.com/MarketSquare/robotframework-tidy/issues/242))
- Add `min_width` parameter to `AlignTestCases` transformer. It allows to set minimal width of data column ([242](https://github.com/MarketSquare/robotframework-tidy/issues/242))
- Changed behaviour of `DiscardEmptySections` transformer. Now by default section with only comments are not considered empty.
Configure `allow_only_comments` to `False` if you want to remove those sections ([235](https://github.com/MarketSquare/robotframework-tidy/issues/235))
- Add `skip_types` parameter to `AlignVariablesSection` which allows to not align variables of particular type ([225](https://github.com/MarketSquare/robotframework-tidy/issues/225))
- Library names are now ignored by default by `RenameKeywords` transformer. Previously, it could result in an unexpected behaviour ([269](https://github.com/MarketSquare/robotframework-tidy/issues/269)).
If you want to transform library names, pass `ignore_library=False` to the transformer.

Other
- Change exceptions to be more user-friendly. Robotidy will try to recognize common mistakes. For unknown issues there is extra message with link to our bug board ([250](https://github.com/MarketSquare/robotframework-tidy/issues/250))
- Refactored Robotidy acceptance tests ([248](https://github.com/MarketSquare/robotframework-tidy/issues/248))
- It is now possible to force overwrite with ``--check`` and ``--overwrite`` flags ([239](https://github.com/MarketSquare/robotframework-tidy/issues/239)).
Going over possible options:

Transform the files and return 0 even if there were files transformed.
commandline
robotidy src


Don't transform the files and return 0 even if there would be files transformed
commandline
robotidy --no-overwrite src


Don't transform the files and return 1 if there would be files transformed
commandline
robotidy --check src


Transform the files and return 1 if there are files transformed
commandline
robotidy --check --overwrite src


Fixes
- Unmodified files are now not saved to the disk ([237](https://github.com/MarketSquare/robotframework-tidy/issues/237))

Fixes
- `AddMissingEnd` transformer now properly handles IFs without indented block of code ([226](https://github.com/MarketSquare/robotframework-tidy/issues/226))
- Paths passed from command line are now checked against excluded paths (previously it was only checked when iterating over directories) ([227](https://github.com/MarketSquare/robotframework-tidy/issues/227))

Fixes
- Trailing whitespace is no longer added to blank lines in multiline statements when using align transformers ([219](https://github.com/MarketSquare/robotframework-tidy/issues/219))
- `*** Tasks ***` is no longer converted to `*** Test Cases ***` by NormalizeSectionHeaderName ([218](https://github.com/MarketSquare/robotframework-tidy/issues/218))

Transformers
- New non default transformer `RenameTestCases`. It capitalizes first letter of the test case name, removes trailing dot and can replace provided regex pattern with substitute string ([183](https://github.com/MarketSquare/robotframework-tidy/issues/183))
- New non default transformer `RenameKeywords`. It applies Title Case to keyword name and replace underscores by spaces and can replace provided regex pattern with substitute string ([183](https://github.com/MarketSquare/robotframework-tidy/issues/183))
- Added `AlignTestCases` transformer for aligning templated test cases in column. Because it's in experimental mode it will be non default for now (see docs for information how to run it) ([185](https://github.com/MarketSquare/robotframework-tidy/issues/185))
- Missing ENDs in for loop and if statements will be added by new `AddMissingEnd` transformer ([91](https://github.com/MarketSquare/robotframework-tidy/issues/91))
- `NormalizeAssignments` now recognizes assignments from ``*** Variables ***`` section separately. It allows you to configure different assignment sign type for keyword calls and for variables section ([159](https://github.com/MarketSquare/robotframework-tidy/issues/159))

With this change following command will change all assignments signs to `=` for keyword calls and remove them in ``*** Variables ***`` sections.

robotidy -c NormalizeAssignments:equal_sign_type=equal_sign -c NormalizeAssignments:equal_sign_type_variables=remove <src>

- New `OrderTags` (non default) transformer. It orders tags in lexicographic order ([205](https://github.com/MarketSquare/robotframework-tidy/issues/205))
- New `NormalizeTags` (non default) transformer. It normalizes tag name case and removes duplicates ([212](https://github.com/MarketSquare/robotframework-tidy/issues/212))

Features
- It is now possible to provide source paths in configuration file ([154](https://github.com/MarketSquare/robotframework-tidy/issues/154))
- Non default transformers can be enabled using ``enabled=True`` parameter ([182](https://github.com/MarketSquare/robotframework-tidy/issues/182))
- Semicolon in parameter value can now be escaped with `\:` ([190](https://github.com/MarketSquare/robotframework-tidy/issues/190))
- Default separator can be changed from space to tabular with new ``--separator`` option ([184](https://github.com/MarketSquare/robotframework-tidy/issues/184))
- ``--lineseparator`` option now accepts `auto` value for preserving line endings found in the file ([209](https://github.com/MarketSquare/robotframework-tidy/issues/209))

Fixes
- Robotidy will not print "Loaded configuration from ... " if the configuration is empty ([193](https://github.com/MarketSquare/robotframework-tidy/issues/193))
- no source path provided error now exits with code 1 instead of 0 ([208](https://github.com/MarketSquare/robotframework-tidy/issues/208))

Other
- ReplaceRunKeywordIf now removes ELSE branch if it is unnecessary ([192](https://github.com/MarketSquare/robotframework-tidy/issues/192))
