Wesley watches for file changes and runs a command of your choosing whenever one is encountered. Wesley is intended to be cross platform and should run equally well on OSx, Linux, and Windows.
Wesley is built in Rust and is presently most easily installed with
Cargo which comes packaged with
Rust.
With Cargo installed, run cargo install wesley. Ensure that ~/.cargo/bin
is on your path and you're good to go.
Usage: wesley [options] COMMAND
Options:
-o, --only PATH only run COMMAND when path that changed matches PATH
-e, --exclude PATH run COMMAND when path doesn't match PATH glob
-h, --help print this help menu
Wesley is quite useful when paired with a test runner or build tool. For
instance, the following will execute npm test whenever a change is detected
in the current directory, automatically executing the test script configured
for a Node.js project.
wesley npm test
Similarly, the following will rebuild the artifact produced for a Java project.
Note the excluded "target/*" path since the compile step will result in changes
to files in the target directory.
wesley -e "target/*" mvn compile
You could even use Wesley to watch changes and rebuild itself.
wesley -e "target/*" cargo build
Wesley doesn't care what command you want to run or what language or platform you might be working with. No judgement here.
