IntelliJ

[John Dewsnip]

Hi,

I have a few questions about running CRaSH as a main in IntelliJ. This is the first time I have run the shell.

1. Is org.crsh.cli.impl.bootstrap.Main the right main to run from IntelliJ?

2. When I run I get the following extra format chars which I am guessing is due incorrect term detection. How do I make them go away?

[1mNAME     [0m DESCRIPTION                                                          

[31mdashboard [0m a monitoring dashboard                                               

[31megrep     [0m search file(s) for lines that match a pattern                        

[31menv       [0m display the term env                                                 

[31mfilter   [0m a filter for a stream of map                                         

[31mjava     [0m various java language commands                                       

[31mjdbc     [0m JDBC connection      

3. I've added extra java based commands and these are on the classpath with the method annotated with @Command. I can't see them in help or run them. What else do I need to do? 

I hope you can help.

Regs.

likely the most convenient way, never really thought about this use case.

by having a proper detection of this use case and reconfiguring the console connector to skip the rendering the style objects which would at some point change this class:

https://github.com/crashub/crash/blob/master/shell/src/main/java/org/crsh/console/jline/JLineProcessor.java

and change:

public void write(Style d) throws IOException {
d.writeAnsiTo(writer);
}



to something like:

public void write(Style d) throws IOException {
if (ansi) {
d.writeAnsiTo(writer);
}
}


Same for “cls”.

Can you put a break point in the class https://github.com/crashub/crash/blob/master/shell/src/main/java/org/crsh/standalone/CRaSH.java at line 366 and let us know if ansi detection happens properly in the blocks:

if (!term.isAnsiSupported()) {
out = AnsiConsole.out;
err = AnsiConsole.err;
} else {
out = new PrintStream(new BufferedOutputStream(new FileOutputStream(FileDescriptor.out), 16384), false);
err = new PrintStream(new BufferedOutputStream(new FileOutputStream(FileDescriptor.err), 16384), false);
}



if that works well, then it would be fairly easy to reconfigure the console connector to add a “ansi” option.

Two solutions:

1/ you provide the code source .java or .groovy and let CRaSH compile it for you with configuration of the source as a mount point provider. classpath:/crash/commands/ is mounted by default, so having the sources in a package crash/commands would work out of the box. See http://www.crashub.org/beta/reference.html#_mount_point_configuration

2/ implement your own CommandResolver that can return classes and declare it as a CRaSH plugin. This test case does exactly that : https://github.com/crashub/crash/blob/master/shell/src/test/java/org/crsh/shell/impl/command/CustomCommandResolverTestCase.java

so I got your scenario working:

1/ so concerning the ansi in Intellij I fixed this issue which allows to run it via system property configuration:

https://jira.exoplatform.org/browse/CRASH-217

This skip ansi escapes in non ansi terminals you need to force the terminal detection to “none” in the system properties with org.crsh.console.jline.terminal set to none.

2/ concerning the detection of commands I used the mount point configuration "classpath:/crash/commands/;file:./src/crash/commands/“

So the Intellij configuration is:

Main class : org.crsh.standalone.CRaSH
VM options : -Dorg.crsh.console.jline.terminal=none
Program arguments : --cmd classpath:/crash/commands/;file:./src/crash/commands/

note that up/down arrows are not supported since this will move the cursor in Intellij.

It works great and will save me a lot of time,

Thanks.

you’re welcome, I added a tip in the reference documentation for running in an IDE : https://github.com/crashub/crash/blob/master/doc/reference/src/main/asciidoc/connectors.asciidoc#terminal-detection
