command-line-interface

问题 I have seen these two questions: Can I change the font of terminal? Is it possible to show mathematical symbols in the terminal? The answer to both is yes. I am wondering if it is possible to have a CLI print out mathematical symbols into the terminal from a custom font only it is personally using , while at the same time I never have to change the font on my terminal (I can keep using the default font for everything else). That is, say I have my default font for my terminal set to x . The

问题 I would like to run PHP in a command-line-interface and I would like to get output after every line I write. I have php.exe in my PATH environment variable. I use php -r "echo 'Hello world'" or php -a Interactive mode enabled <?php echo "hello world" ?> ^Z But I want a real php shell, which reacts after every command.

问题 So when I run this on a mac: awk 'END { for (name in ENVIRON) { print "key: "name; } }' >> app-deployment.yaml awk just freezes. If I change it to just print to /dev/null like this awk 'END { for (name in ENVIRON) { print "key: "name; } }' < /dev/null It works fine. Am I doing something wrong with my redirection? Is there something else I'm doing wrong here? 回答1: Change END to BEGIN to be able to work without any input: awk 'BEGIN { for (name in ENVIRON) { print "key: "name; } }' >> app

问题 One of the improvements in PHP7.1 is that in Windows the readline extension is available out of the box. I'm having trouble using all of the functions though, as they don't all exist. The following code: $functions = [ 'readline_add_history', 'readline_callback_handler_install', 'readline_callback_handler_remove', 'readline_callback_read_char', 'readline_clear_history', 'readline_completion_function', 'readline_info', 'readline_list_history', 'readline_on_new_line', 'readline_read_history',

问题 I have a very similar issue to Excluding a directory from Jekyll watch, but I thought it was different enough to warrant it's own question. _config.yml: exclude: [ "my_ignored_directory" ] Using jekyll build --watch , the folder my_ignored_directory will be successfully ignored from the watch task, but it will also not be built. Is there are way to exclude a folder of my choosing from the --watch task, but not to be excluded from being built? (Note: there is no error in the console) 回答1: The

问题 I am trying to build an app made with Angular2 + Ionic2 (ie. Cordova 6) for my android 4.4.4. I have noticed the version 4.4.4 of android was reffered to the api level 20, so this is the version I have downloaded and installed (api20 + android SDK Build Tools level 20 too). In cordova I have edited the platforms/android/project.properties and platforms/android/CordovaLib/project.properties to build to android-2O instead of the default android-23 api. I have also edited the AndroidManifest.xml
