# Release Notes for Scour
|
|
|
|
## Version 0.35 (not released yet)
|
|
|
|
* Drop official support for Python 2.6. (While it will probably continue to work for a while compatibility is not guaranteed anymore. If you continue to use Scour with Python 2.6 and should find/fix any compatibility issues pull requests are welcome, though.)
|
|
* Fix: Unused IDs were not shortended when `--shorten-ids` was used. ([#19](https://github.com/scour-project/scour/issues/62))
|
|
* Fix: Most elements were still removed from `<defs>` when `--keep-unreferenced-defs` was used. ([#62](https://github.com/scour-project/scour/issues/62))
|
|
* Improve escaping of single/double quotes ('/") in attributes. ([#64](https://github.com/scour-project/scour/issues/64))
|
|
* Print usage information if no input file was specified (and no data is available from `stdin`). ([#65](https://github.com/scour-project/scour/issues/65))
|
|
* Redirect informational output to `stderr` when SVG is output to `stdout`. ([#67](https://github.com/scour-project/scour/issues/67))
|
|
* Allow elements to be found via `Document.getElementById()` in the minidom document returned by scourXmlFile(). ([#68](https://github.com/scour-project/scour/issues/68))
|
|
* Improve code to remove default attribute values and add a lot of new default values. ([#70](https://github.com/scour-project/scour/issues/70))
|
|
* Fix: Only attempt to group elements that the content model allows to be children of a `<g>` when `--create-groups` is specified. ([#98](https://github.com/scour-project/scour/issues/98))
|
|
* Fix: Update list of SVG presentation attributes allowing more styles to be converted to attributes and remove two entries (`line-height` and `visibility`) that were actually invalid. ([#99](https://github.com/scour-project/scour/issues/99))
|
|
* Add three options that work analoguous to `--remove-metadata` (removes `<metadata>` elements) ([#102](https://github.com/scour-project/scour/issues/102))
|
|
* `--remove-titles` (removes `<title>` elements)
|
|
* `--remove-descriptions` (removes `<desc>` elements)
|
|
* `--remove-descriptive-elements` (removes all of the descriptive elements, i.e. `<title>`, `<desc>` and `<metadata>`)
|
|
* Fix removal rules for the `overflow` attribute. ([#104](https://github.com/scour-project/scour/issues/104))
|
|
* Improvement: Automatically order all attributes ([#105](https://github.com/scour-project/scour/issues/105)), as well as `style` declarations ([#107](https://github.com/scour-project/scour/issues/107)) allowing for a constant output across multiple runs of Scour. Before order could change arbitrarily.
|
|
* Improve path scouring. ([#108](https://github.com/scour-project/scour/issues/108))<br>Notably Scour performs all caculations with enhanced precision now, guaranteeing maximum accuracy when optimizing path data. Numerical precision is reduced as a last step of the optimization according to the `--precision` option.
|
|
* Fix replacement of removed duplicate gradients if the `fill`/`stroke` properties contained a fallback. ([#109](https://github.com/scour-project/scour/issues/109))
|
|
* Fix conversion of cubic Bézier "curveto" commands into "shorthand/smooth curveto" commands. ([#110](https://github.com/scour-project/scour/issues/110))
|
|
* Fix some issues due to removal of properties without considering inheritance rules. ([#111](https://github.com/scour-project/scour/issues/111))
|
|
|
|
|
|
## Version 0.34 (2016-07-25)
|
|
|
|
* Add a function to sanitize an arbitrary Python object containing options for Scour as attributes (usage: `Scour.sanitizeOptions(options)`).<br>This simplifies usage of the Scour module by other scripts while avoiding any compatibility issues that might arise when options are added/removed/renamed in Scour. ([#44](https://github.com/scour-project/scour/issues/44))
|
|
* Input/output file can now be specified as positional arguments (e.g. `scour input.svg output.svg`). ([#46](https://github.com/scour-project/scour/issues/46))
|
|
* Improve `--help` output by intuitively arranging options in groups. ([#46](https://github.com/scour-project/scour/issues/46))
|
|
* Add option `--error-on-flowtext` to raise an exception whenever a non-standard `<flowText>` element is found (which is only supported in Inkscape). If this option is not specified a warning will be shown. ([#53](https://github.com/scour-project/scour/issues/53))
|
|
* Automate tests with continouous integration via Travis. ([#52](https://github.com/scour-project/scour/issues/52))
|
|
|
|
|
|
## Version 0.33 (2016-01-29)
|
|
|
|
* Add support for removal of editor data of Sketch. ([#37](https://github.com/scour-project/scour/issues/37))
|
|
* Add option `--verbose` (or `-v`) to show detailed statistics after running Scour. By default only a single line containing the most important information is output now.
|
|
|
|
|
|
## Version 0.32 (2015-12-10)
|
|
|
|
* Add functionality to remove unused XML namespace declarations from the `<svg>` root element. ([#14](https://github.com/scour-project/scour/issues/14))
|
|
* Restore unittests which were lost during move to GitHub. ([#24](https://github.com/scour-project/scour/issues/24))
|
|
* Fix a potential regex matching issue in `points` attribute of `<polygon>` and `<polyline>` elements. ([#24](https://github.com/scour-project/scour/issues/24))
|
|
* Fix a crash with `points` attribute of `<polygon>` and `<polyline>` starting with a negative number. ([#24](https://github.com/scour-project/scour/issues/24))
|
|
* Fix encoding issues when input file contained unicode characters. ([#27](https://github.com/scour-project/scour/issues/27))
|
|
* Fix encoding issues when using `stding`/`stdout` as input/output. ([#27](https://github.com/scour-project/scour/issues/27))
|
|
* Fix removal of comments. If a node contained multiple comments usually not all of them were removed. ([#28](https://github.com/scour-project/scour/issues/28))
|
|
|
|
|
|
## Version 0.31 (2015-11-16)
|
|
|
|
* Ensure Python 3 compatibility. ([#8](https://github.com/scour-project/scour/issues/8))
|
|
* Add option `--nindent` to set the number of spaces/tabs used for indentation (defaults to 1). ([#13](https://github.com/scour-project/scour/issues/13))
|
|
* Add option `--no-line-breaks` to suppress output of line breaks and indentation altogether. ([#13](https://github.com/scour-project/scour/issues/13))
|
|
* Add option `--strip-xml-space` which removes the specification of `xml:space="preserve"` on the `<svg>` root element which would otherwise disallow Scour to make any whitespace changes in output. ([#13](https://github.com/scour-project/scour/issues/13))
|
|
|
|
|
|
## Version 0.30 (2014-08-05)

|
|
* Add option to ingore unknown cmd line opts.
|
|
|
|
|
|
## Version 0.28 (2014-01-12)
