Command-line options

You can configure Logisim's application preferences via command line options. This can be particularly useful in a laboratory of single-student computers where you want Logisim to start up the same for students every time, regardless of how previous students may have configured the program.

The overall command-line syntax is as follows.

java -jar jarFileName [options] [filenames]
The optional additional files named on the command line will be opened as separate windows within Logisim.

The following example starts Logisim in its basic configuration.

java -jar jarFileName -plain -gates shaped -locale en

Supported options include the following.

-template templateFile

Configures the template for Logisim to use.

-gates [shaped|rectangular]

Configures which type of gate to use.

-locale localeIdentifier

Configures which translation to use. As of this writing, the supported locales include:

-accents [yes|no]

This is only relevant for languages that use characters outside the 7-bit ASCII character set; this would include languages using accented characters, and it would not include English. If no, characters outside the 7-bit ASCII character set are replaced with equivalents appropriate to the language; this would be useful for Java/OS combinations where such characters are not supported well.
