阅读更多关于 Linux - moving the console cursor visual

问题 I'm currently designing a CLI interface for linux, and for various reasons I am not able to use ncurses . I am using exclusively C++ and the Qt framework.

I have already implemented command completion and command history(like when you press tab or

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I've seen a Mac OS X git demo online in which it's configured to have multiple colors.

Can you tell me how can I configure Mac OS X terminal to achieve that? It's definitely

Is there a way to check before adding module to JBoss using CLI?

阅读更多关于 Is there a way to check before adding module to JBoss using CLI?

Is there a way to check module hasn't already been added before calling adding using JBoss CLI? e.g. module add --name=org.mysql --resources=/home/abc/drivers/mysql/MySQL5.jar # Want to do similar check for module add if (outcome != success) of /subsystem=datasources/jdbc-driver=org.mysql:read-resource # Add it... end-if Reason is trying to add a module that already exists causes an error. When in domain mode, you can do that. Here's how you can check a module's existence: if (outcome != success) of /host=master/core-service=module-loading/:list-resource-loader-paths(module=your.module.name)

Xdebug laravel artisan commands

I regularly use xdebug to debug applications, I've built a laravel application that takes an upload of a csv inserts the data to the database and the ids to a job queue. I've written an artisan command to be run via cron to then do something with this data. Xdebug works for accessing the site via the browser, but its not breaking on breakpoints when ran from cli. I run php5-fpm. My files /etc/php5/fpm/php.ini and /etc/php5/cli/php/ini both contain the following settings: zend_extension=/usr/lib/php5/20121212/xdebug.so xdebug.remote_enable = 1 xdebug.idekey = 'dev_docker' xdebug.remote

Python Curses without clearing screen

This question was migrated from Software Engineering Stack Exchange because it can be answered on Stack Overflow. Migrated 5 years ago . Learn more .

It is acceptable, though not preferred, to leave the ugly pieces of the pop up menu on the screen upon exit. The idea is to use it for quick practical sysadmin apps and scripts where aesthetics is not important. It seems that the Python init functions always clear the
