Export CodeTour files to md

CodeTour is a fantastic extension for VSCode. Kudos to the authors.
Every CodeTour contains steps.
Each step has a description and a link to the file and line number in the source code.
No more out of sync examples in the documentation.
This type of documentation is meant to be used for code flow explanation.
To show other programmers the important information step by step in a logical order for humans.
This extension for now works only inside VSCode. That is a problem for coders with other editors.
In the present version (2020-04-27) the extension has no functionality to export to a markdown file.
I don't have enough knowledge in vs code extensions and Typescript to make a PR contribution.
So I make a rust tiny small CLI program.
I prepared this project as a proof of concept how the "export to md" could look like.
The resulting md is very nice. It is a file and therefore it can be committed to Github.
In the md there are links to the source code on Github.
This way all coders can follow the code flow on the actual code.
I copied to the folder example/ a few files from my other project where I use CodeTour.
There are 2 similar *.tour files. The CLI will export all tours files in that folder.
Without any arguments the CLI will look at the standard
If the files are in another folder, like for my example, the argument is like this:
GitHub and working example
In my other project I tried to write some documentation about the code flow.
It was horrific.
I avoided copy/paste the source code because in no time it is obsolete and misleading.
Now I exported the md from CodeTour and it is amazing:
The step by step approach jumping from module to module is great.
It just hides all the other non-important code for basic human understanding of the code flow.
And the links are "alive", they go to the actual code in Github.
I use it inside
makefile.toml when creating docs like this:\
[tasks.doc] description = "cargo doc - create docs from doc comments" clear = true script= [ "echo $ lmake_readme", # copy data from cargo.toml to readme.md, then include text from readme.md into *.rs doc comments "lmake_readme", "echo $ cargo doc --no-deps --document-private-items", # create doc from doc comments "cargo doc --no-deps --document-private-items", "echo $ codetour_export_to_md", # export code tour to md "codetour_export_to_md", # copy to /docs/ because it is github standard "echo $ rsync -a --info=progress2 --delete-after target/doc docs", "rsync -a --info=progress2 --delete-after target/doc docs", # message to help user with next move "echo after successful doc, run cargo make fmt msg_for_commit", ]
Install from crates.io:
cargo install codetour_export_to_md
run with no parameters. Best together with
Clone the repo
git clone email@example.com:bestia-dev/codetour_export_to_md.git
Use prepared cargo make scripts:
clear; cargo make release
clear; cargo make run_rel2
The result is :
