问题 Morning guys, I am writing a small Ruby CLI app for myself, and I have run into a small issue that I hope you guys can help with. Apologies if this is a stupid question, I am very new to Ruby. I am using https://github.com/davetron5000/gli as a foundation to build my my app since they make it easy to have all my commands and whatnot. Question is, while I develop the app, I can run it using bundle exec bin/konstruct , but that only works from the folder where the code lies. I want to run the

问题 I'm working on a project based on the Laravel 4 framework. The framework is awesome, the website works great, no problem with that. But I also have to write several scripts, mostly DB maintenance tasks that will be scheduled in a crontab. I'm looking for a way to write these scripts in the same flavour as the web-site code. Or at least, re-use the models and if possible some other framework features. Is there a way to do that ? Thanks in advance :) Answer : Artisan Commands are indeed the way

问题 I'm using the Commander gem to write a small console utility. I want to set a default command when user does not specify any. I found how to do through the API: Commander::Runner.instance.default_command(:gui) but I thought there would be a simpler and more straightforward way. I just can't find it using Internet search. 回答1: It's right in the docs, you should find what you need here https://github.com/tj/commander#command-defaults It should be as simple as default_command :command_name 来源：

问题 I need to set an environment variable from Node (currently using v8.9.3 ) Ideally, I would like to run export DATA_DIR=/var/lib/data when the program starts. 1. Tried spawning a child_process to set this, but it does not appear to work. Example: const { spawnSync } = require( 'child_process' ); spawnSync( 'export', [ 'DATA_DIR=/var/lib/data' ] ); But this results with an ENOENT : Error: spawnSync export ENOENT... code: 'ENOENT', errno: 'ENOENT', syscall: 'spawnSync export', path: 'export',

问题 I am trying to merge a merge request (Gitlab) from command line. After working on a dummy repository, I came to know that if I have the permission to merge a merge request, I can merge them directly through command line. I started by cloning the upstream repository in my local system. After that, I made a change in my forked repository and created a merge request for the same. While manually trying to merge the request from command line using this approach, I am getting an extra commit which

问题 When I'm writing a php -f program.php command in my CLI, i get no response. I have tried to write php -h command or php -r 'echo 'try' command or php -i command and I still get no response.

问题 I wonder if anyone knows how to debug R script in a linux environment using command line. For example, in python we can use pdb. We first set a break point (pdb.set_trace()), we then can use command like 'c','n','s','b', etc. to debug the python code in the linux environment. I have been searching lots of information for R debugging, but so far I did not find a similar function in R. Thank you very much for your help! 来源： https://stackoverflow.com/questions/50518418/rscript-debug-using
