![]() ![]() ![]() It will render text Contribution linking to heading with id=contribution. This means if the script produces line like this: - (#contribution) To bring us back on track, our goal in this section was to output markdown link, which will contain the same ID as the heading after the rendering to HTML. Side note: For example Gitea already reverted this feature and Gitlab already has one issue open. They are prefixing the ID like this probably to avoid users to create HTML elements with same IDs as IDs of other elements in GitHub web pages. This is specific for sites such as GitHub and Gitlab. So now you ask why the heck is the element ID of heading prefixed with user-content. Here is example how the ToC link (#contribution) is rendered in GitHub: ContributionĪnd this is example how the heading is rendered in GitHub (note that it also points to itself): This kind of anchor part ending with # is called fragment identifier.įor example this anchor has fragment identifier #section-one and after clicking your browser will be moved to HTML element with element ID set to id=section-one. This is why clicking on some links will move your browser to correct place inside of the same page. It’s not that simple, because of how anchor links look like after they are rendered from markdown file to HTML web page.Īs you know an link anchor in HTML page can point to an element within an HTML document. The script will just output the markdown links formatted in list with correct indentation based on level of heading and we are done.īut! But it will not that simple! Markdown Links This theoretically should be sufficient in order to produce ToC. Ignore text when line starts with code block ``` until the code block ends.The code blocks start and end with three backticks ```. Many languages are using # as sign to comment a line and as mentioned above the # in markdown indicates start of the heading. Code BlocksĪs second thing, I wanted to not produce links from lines in code blocks. In this case an array will be sufficient, because order of lines in ToC will be the same as when we iterate over the file. Main goal in my algorithm is therefore to get all lines starting with a # sign and save them in some kind of data structure. The headings also have levels: - # is heading level 1 - # is subheading of the previous # - The same for more nested headings up to six ( #) So for example clicking on link will directly move your browser to heading to-start-developing-k8s. This HTML page contains special navigation links generated from the markdown headings which are denoted by # sign. Markdown engines are used to produce HTML page. In this blog I will describe what was my development approach and obstacles that I hit on the way. Why not write a simple bash script with no dependencies that can generate ToC from any markdown file correctly? It should not be a big deal and bash could handle it very well.Īnd so I created ToC generator in bash and answered the question on StackOverflow. There were scripts and programs written in every popular language, but nobody answered with a bash script that can generate it. ![]() So I did my research on what tools people use to create ToC and came across this StackOverflow question which contained a lot of scripts that can help with this task. If you manage multiple git repositories with README.md in each of them, writing ToC is a time consuming job. To have a better overview what is inside of this one big markdown file it is suitable to include Table of Contents (ToC) on the top of it. ![]() Generating Table of Contents for Markdown Fileįrom time to time everyone will produce bigger markdown file for documentation purposes. ![]()
