css - Recreate Similar Travis CI Console Log Interface -


the first time saw travis ci live updating build console log, was, i'll admit, nerdily impressed. , know time consuming css styling , js coding, half nice. but, question is, there libraries out there make building easier? realize travis ci uses ember web app framework, i'm guessing isn't component of ember, right?

travis ci console log

"travis-web" uses ember, functionality "log-container" custom. contains text of log file ("download log"). please download raw version of log , take look.

you see, log file has several "annotations". it's syntax indicate areas, custom styles applied. these lines processed log script , removed.

ok, let's decompose this:

► code-folds

folds start "travis_fold:start:section_name" , end "travis_fold:end:section_name"

the content inside fold placed in span. default span height 0. content not shown.

on-click, additional css-style open added span. style open sets height of span element auto - , content of fold show up.

line-numbers ://url#l100

the annotations removed form log file content

(total number of lines = raw log file lines - annotation lines).

all lines numbers anchor elements (a), line-wise referencing possible.

the numbering done css - number added before anchor.

log-body p a::before { content: counter(line-numbering); counter-increment: line-numbering;

colors

throughout raw log file ansi-color codes used. content parsed ansiparser script , color-codes converted (deansi'ed) css-class color names.

the string

[0k[33;1mbuild system information[0m

becomes

<span id="1-3" class="yellow bold">build system information</span>

scroll-to-end-of-log & move top

scroll-to-end-of-log similar scroll end of div: this.scrollintoview(false);

when scrolling activated, activation button top positioned keep @ same spot.

the "move top" bottom positioned.

active line hovering

the current cursor line styled p:hover: #color.

section , duration display

on right side "section or folder name" , "duration" show. both spans based on following markers:

travis_time:start:0759cab0

cmds

travis_time:end:0759cab0:start=1434311411734827664,finish=1434311413318517466, duration=1583689802


but, question is, there libraries out there make building easier?

for small site, use themeable javascript based codeeditor, codemirror.

apply dark-theme, add custom rules code-folding , code-highlighting, active-line hovering. pretty close in no time.
