zeeds (Zero dEpendency sEEDS)

Too small for their own repository. Too useful to not exist.

Zero-dependency Java 25+ source files designed as starting points for your projects. Run directly with java filename.java — no compilation step needed. Each zeed is self-contained, using only JDK APIs. Copy, customize, extend.

Only Java 25+ is required, no external dependencies.

• zcbs — Save clipboard content to a file. Usage: ./zcbs <filename>

• zwrap — Wrap a Java script with additional parameters. Usage: ./zwrap <script> [args...]
• zmkdir — Create year/month directories. Usage: ./zmkdir -f (flat: 2026.01) or ./zmkdir -n (nested: 2026/01)

• ztwins — Find files with identical content. Usage: ./ztwins <file> <directory>
• zdate — Print and copy today's date to the clipboard. Usage: ./zdate (dd.MM.yyyy) or ./zdate -y (yyyy.MM.dd)
• zheader — Prepend a copyright / license header from the clipboard to all .java files recursively, skipping files that already contain it. Usage: ./zheader [dir] [-dry]
• zimginfo — Print image dimensions and file size. Usage: ./zimginfo <image-file>
• zlaunch — Load environment entries from properties files, then launch an application. Usage: ./zlaunch <command> [args...]
• zjdocfind — Find and open javadoc for a type by simple or fully qualified name. Usage: ./zjdocfind String or ./zjdocfind java.lang.String
• zzip — Zip a directory into a .zip file. Usage: ./zzip <directory>
• zgitr — List git remotes (fetch and push) from the current repository's .git/config. Usage: ./zgitr
• zourl — Open a configured URI with the system's default application. Usage: ./zourl or ./zourl -Duri=https://github.com
• zbump — Bump version.txt using a yyyy.MM.dd.NN per-day sequence, searching the current directory upwards (and src/main/resources). Usage: ./zbump
• znotes — Append timestamped thoughts to a Markdown notes file (folder configurable via zcfg). Usage: ./znotes <thought>, ./znotes -l (list), or ./znotes -o (open)
• zf2cb — Load a file into the system clipboard. Usage: ./zf2cb <file>
• zcbxmlstrip — Strip XML/HTML markup from clipboard text, in place. Usage: ./zcbxmlstrip
• zlsbc — List all business components (BCs) — directories containing a boundary, control, or entity layer — with colored output. Prints the component name by default, or the path relative to the given directory with -full. Usage: ./zlsbc [directory] (defaults to the current directory) or ./zlsbc [directory] -full
• zlinediff — Compare two text files line by line and list differing lines with colored output; exits with 1 if the files differ. Usage: ./zlinediff <left> <right>
