bug #14623 [Console] SymfonyStyle : fix & automate block gaps. (ogizanagi)
This PR was merged into the 2.7 branch. Discussion ---------- [Console] SymfonyStyle : fix & automate block gaps. | Q | A | ------------- | --- | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | - | License | MIT | Doc PR | - --- Depends on https://github.com/symfony/symfony/pull/14741 --- ## What it does - autoprepend appropriate blocks (like cautions, titles, sections, ...) by the correct number of blank lines considering history. - handle automatically most of the SymfonyStyle guide line breaks and gaps. Fix things such as unwanted double blank lines between titles and admonitions. - test outputs - fix an issue using questions with SymfonyStyle, which should not output extra blank lines when using with a non-interactive input. ## Description `SymfonyStyle` is great, but there are some issues, mostly when using blocks (text blocks, titles and admonitions): some extra blank lines might be generated. Plus, on the contrary, some line breaks or blank lines around blocks are missing, and the developer need to handle this himself by polluting his code with ugly `if` and `newLine()` statements. ### Before / After : ![screenshot 2015-05-13 a 00 11 59](https://cloud.githubusercontent.com/assets/2211145/7600572/ccfa8904-f90c-11e4-999f-d89612360424.PNG) As you can see, it's still up to the developper to end his command by a blank line (unless using a block like `SymfonyStyle::success()`) in order to distinct different commands outputs more efficiently. Everything else is now handled properly, and automatically, according to the rules exposed in the symfony console style guide published some time ago by @javiereguiluz . Questions (not exposed in the above output) are considered as blocks, and follow, for instance, the same conditions than admonitions: 1 blank line before and after, no more (although, you'll still be able to output more blank lines yourself, using `newLine`).
