[Console][Progress Bar] Output progress in --no-ansi #11542
Comments

If your application does not support the overwriting sequence char, the output of the progress bar will be completely broken (each display of the progress bar will be appended to the output instead of replacing the previous one). This is why it is disabled. The disabling is based on the color support detection, which was the best choice we could make without adding a separate option for the output (which would not have been BC), even if Windows can actually support the overwriting sequence without supporting color sequences. |

@stof, do you think it would be of any use to display some form of progress even in those cases? Something small such as 0% where each interval of progress is displayed on a new line (which should be supported everywhere). The best, in my opinion, would be to display the text part of the progress bar, with each increment on a new line. 0/3 0% 1 sec/1 sec 1.0 MB It would possibly necessitate to define some value for that increment so that not every call to |

I am also interested in this - especially @tomzx's increment value idea. For instance, if you set the increment value to For a job that takes several minutes to run in a non-decorated environment (such as jenkins) it would be nice to see something... Not sure if the |

…allow non-decorated output (kbond) This PR was merged into the 2.6-dev branch. Discussion ---------- [Console] add overwrite flag to ProgressBar helper to allow non-decorated output | Q | A | ------------- | --- | Bug fix? | no | New feature? | yes | BC breaks? | yes, but not critical | Deprecations? | no | Tests pass? | yes | Fixed tickets | #11542, #10011 | License | MIT | Doc PR | symfony/symfony-docs#4206 By default, the `ProgressBar` helper overwrites the output to give the nice progress bar look. To prevent the output from blowing up in non-decorated environments, the output was hidden in these environments (see #9846). This PR enables using the `ProgressBar` in non-decorated environments by adding an `overwrite` flag. When `false`, instead of overwriting the bar, it is rendered on a new line. To prevent flooding the output, you can adjust the `redrawFrequency`. By default, when using the `ProgressBar` in a non-decorated environment, the `overwrite` flag is set to false. If a `max` is set, the `redrawFrequency` is set to a sensible default (10% of the max). If a `max` isn't set, the bar is output for every advance so to prevent flooding, a sensible `redrawFrequency` should be manually set. The only BC break is that output will now display where it didn't before. Commits ------- cdee6f6 add overwrite flag to allow non-decorated output
Hi,
We use the progress bar console component to display progress in one of our command that takes a while to execute. Sadly, when this command is executed during continuous integration (jenkins), no progress is displayed.
Based on the reading I've had on the subject (#9511 #10011), I understand it was decided not to display anything if
--no-ansiis set/detected.Is this assertion correct? If so, is there any way to use the progress bar component to display some form of progress for applications such as jenkins which most likely do not support overwriting sequence characters?
Thanks!
Note:
--no-ansiis not passed to the console when executing said command.The text was updated successfully, but these errors were encountered:
