Stupid

A stupid tool to write a portable Makefile for a Go project.

It provides simple commands to bridge the differences between the behaviors of the shells invoked from a typical Makefile by GNU Make.

All commands which manipulate files and directories should take linux-style paths as inputs, e.g. be made of forward slashes.

Wildcard expansion for source files are performed for * and ? meaning they can be used even if the underlying shell does not support them.

Available commands:

• cp
• date
• home
• mkdir
• rm
• silence
• tar
• untar

Installation

go get -u github.com/jeanlaurent/stupid/cmd/stupid

Most systems have GNU Make available through their package manager.

For Windows the GnuWin32 Make albeit a bit outdated has been known to work well.

Commands

cp

stupid cp SRCS DST

Copies files and directories listed in SRCS into DST, with the following behavior:

• existing files are overwritten
• permissions are replicated
• directories are copied recursively
• SRCS are globbed before processing
• DST is created if needed with all intermediate directories
• DST is a directory if any of the following is true:
  • DST already exists and is a directory
  • DST ends with a trailing slash
  • SRCS has more than one source
  • SRCS is a single source directory
• DST is a file if one of the following is true
  • DST already exists and is a file
  • SRCS is a single source file and DST does not end with a trailing slash

Example:

stupid cp web/readme.txt web/dist/* electron/web

date

stupid date

Prints the current date with RFC3339.

home

stupid home

Prints the home directory of the current user.

The exact format is platform dependent (e.g. the result can contain back or forward slashes or both) and may contain spaces, therefore it should be quoted when used.

Example:

stupid cp build/library.yaml "$(shell stupid home)/.tootool/"

mkdir

stupid mkdir SRCS

Creates the directories listed in SRCS, with the following behavior:

• already existing directories are skipped
• intermediate directories for each source in SRCS are created

Example:

stupid mkdir bin out/tmp

rm

stupid rm SRCS

Removes the files and directories listed in SRCS, with the following behavior:

• non existing sources are ignored
• directories are removed recursively
• SRCS are globbed before processing

Example:

stupid rm build/*.tar.gz electron/web

silence

stupid silence

Discards everything received on the standard input.

Example:

stupid rm build | stupid silence

tar

stupid tar SRCS DST

Creates a DST tar archive containing the files and directories listed in SRCS, with the additional behavior:

• directories are processed recursively
• intermediate directories for DST are created
• SRCS are globbed before processing
• if DST extension is .tar.gz or .tgz it also applies gzip compression
• if DST is - the archive is written to the standard output

Example:

stupid tar project.app readme.txt build/project-darwin.tar.gz

untar

stupid untar SRC DST

Extracts from a SRC tar archive to the DST directory, with the following behavior:

• DST is created if needed with all intermediate directories
• SRCS are globbed before processing
• if SRC extension is .tar.gz or .tgz it also performs gzip decompression
• if SRC is - the archive is read from the standard input

Example:

stupid untar pony.tar.gz deps/github.com/ponies
