Github flavored markdown "wiki" tools. Supports authoring interlinked pages and support for github issues linking.

This is developed for a github.com rendered repo with a flat-directory (no nested folders) containing markdown files that link to one another as well as internal github issues.

But it will likely also be useful on other markdown projects (mkdocs, hugo) as well.

An example Makefile using pandoc to generate a giant interlinked pdf file from all markdown files.

check file names, headers, and links between *.md files.

TODO: add line number and improve messages. maybe rewrite in compiled language.

1. file names are lowercase - separated .md files
2. first header in a file is also it's name (case insensitive, spaces translated to -)
   • does not check header rules for readme.md or index.md
3. all headers are uniquely named across all files
4. when [blah][file.md#header1] is written
   • file.md exists
   • file.md has some header named header1 (line in file like ## header1)
5. optionally: can check or "orphan" headers that are never linked to

echo -e "# testing\n## [dne](test.md#does-not-exist)" > test.md
wiki-lint.pl

WANRING: test.md: first header should be match filename not 'testing'

test.md: test.md#does-not-exist link does not exist

This file/emacs package contains functions for quickly linking topics between files.

Use M-x list-packages to install quelpa-use-package. then add below to e.g. $HOME/.config/emacs/init.el.

(use-package gfm-wiki
  :quelpa ((gfm-wiki :fetcher github :repo "NPACore/gfm-wiki") :upgrade t)
  :bind (:map markdown-mode-map
              ("C-c M-l" . #'gfm-wiki-insert-link-header)
              ("C-c M-L" . #'gfm-wiki-insert-link)
              ("C-c M-i" . #'gfm-wiki-insert-issue)
              ("C-c M-d" . #'gfm-wiki-deft)
              ;; other packages  -- better to define elsewhere
              ("C-c l"   . #'link-hint-open-link)
              ("C-c g"   . #'git-link)
              ))

• gfm-wiki-repo-name contains the prefix for issues. github.com will render a link from anything thing that looks like org/repo#id-num. This variable stores the org/repo part. (The id-num is fetched by gfm-wiki-insert-issue)

  • consider ((markdown-mode . ((gfm-wiki-repo-name . "NPACore/gfm-wiki")))) in .dir-local.el
  • TODO: pull this from git remote -v|grep -Pom1 '(?<=github.com.).*(?=.git )'

• gfm-wiki-insert-issue command for getting issue number (to insert) and title (for search). Currently using git-bug|jq after git bug bridge with github. See Makefile.example's git-bug entry.

• gfm-wiki-mkdocs-root changes link insert to add a prefix (likely "/"). Setting this to non-nil has the side-effect of also stripping the .md suffix.

  • consider .dir-locals.el: ((markdown-mode . ((gfm-wiki-mkdocs-root . "/"))))
  • TODO: update link/ffap to follow these links
  • TODO: wiki-lint.pl should understand mkdocs links too

• gfm-wiki-insert-link-header shells out to perl for finding headers.
• gfm-wiki-insert-issues uses git-bug and jq to insert issues bridged to github.
• gfm-wiki-deft wraps emacs package deft for a open/create files with search narrowing Consider modify gfm-wiki-issue-cmd to use gh instead.
• The emacs package ivy is used for "completing-read" functions.

• link-hint is especially useful for quickly jumping from any link on the screen.
• git-link to get or goto a github link of current file
