Watches your .go files in a directory and invokes go build if
a file changed. Nothing more.
Usage:
$ ./CompileDaemon -directory=yourproject/
| Option | Default | Description |
|---|---|---|
| actions | ||
-build=… |
go build | Specify the command to run when rebuilding is required. |
-command=… |
none | Specify the command to run after a succesful build. The default is to run nothing. This command is issued with the working directory set to -directory. |
| file selection | ||
-directory=… |
. | Which directory to watch. |
-recursive=… |
true | Recurse down the specified directory |
-exclude-dir=… |
none | Do not watch directories matching this glob pattern, e.g. ".git". You may have multiples of this flag. |
-exclude=… |
none | Exclude files matching this glob pattern, e.g. ".#*" ignores emacs temporary files. You may have multiples of this flag. |
-include=… |
none | Include files whose last path component matches this glob pattern. You may have multiples of this flag. |
-pattern=… |
(.+\.go|.+\.c)$ | A regular expression which matches the files to watch. The default watches .go and .c files. |
In its simplest form, the defaults will do. With the current working directory set to the source directory you can simply…
$ CompileDaemon
… and it will recompile your code whenever you save a source file.
If you want it to also run your program each time it builds you might add…
$ CompileDaemon -command="./MyProgram -my-options"
… and it will also keep a copy of your program running. Killing the old one and starting a new one each time you build.
You may find that you need to exclude some directories and files from monitoring, such as a .git repository or emacs temporary files…
$ CompileDaemon -exclude-dir=.git -exclude=".#*" …
If you want to monitor files other than .go and .c files you might…
$ CompileDaemon -include=Makefile -include="*.less" -include="*.tmpl"
If you get an error for too many open files, you might wish to exclude your .git, .hg, or similar VCS directories using -exclude-dir=…. This is common on OS X and BSD platforms where each watched file consumes a file descriptor.
If you still have too many open files, then you need to raise your process's file limit using the ulimit command. Something like ulimit -n 1024 will probably take care of it. There is also a sysctl based limit which you may reach and need to adjust.
