Bash script generator with bashew30 Dec 2020
I have archived my project
bash_boilerplate and started a better one
I have worked a lot on bashew the last months, and now that it has matured enough, I also updated the
toolstud.io bash boilerplate script generator:
What is bashew?
bashew (rhymes with ‘bash new‘) is a tool for creating bash scripts.
bashew is for developers who write bash/shell scripts, beginners as well as experienced. Bashew provides you with boilerplate code for the following features:
- option/parameter parsing: you specify the possible flags, options and parameters (
script --flag1 -v --option1=value parameter1 [optional parameter2]) only in 1 place, and this will take care of usage printout (‘help text’), option initialisation, option parsing and processing (e.g.
--option1=valuewill be available in your script as a
- flexible output: some output belongs on stdout, some on stderr, sometimes you want to log to a file. Verbose (
-v) and Quiet (
-q) mode are built-in.
- config files: script will automatically use .env config files if they exist, either in the installation folder or in the current folder
- dependency checking: if your script depends on some other programs being installed (like imagemagick, ffmpeg, …) , the script can check this and inform the user how to install it (
- everything is a function: this technique removes the worry that you might call a function before it’s been read in the script, It also make the script very readable (all the custom code is in the beginning of the script).
- temp folder: for temporary files (deleted after the script finishes) and cache files (to remember the result of a slow operation)
- version from repo: the correct version of the script can be saved in a VERSION.md file (which can be automatically updated with pforret/setver), so you never have to update a version number in the script.
For the more advanced users, there are also the necessary files to do CI/CD (continuous integration/continuous deployment) with github actions, with bash_unit (unit testing) and shellcheck (code linting).
