command-line-interface

I'm writing a command line tool with Swift and I'm having trouble displaying colors in my shell. I'm using the following code: println("\033[31;32mhey\033[39;39m") or even NSFileHandle.fileHandleWithStandardOutput().writeData("\033[31;32mhey\033[39;39m".dataUsingEncoding(NSASCIIStringEncoding, allowLossyConversion: true)!) It works when I use a simple echo in php (the text is displayed in green) but is there a reason it doesn't work in a Swift command line tool? Thanks! cyt Swift has built in unicode support. This invalidates using of back slash. So that I use color codes with "\u{}" syntax.

Does APC module in PHP when running in CLI mode support code optimization? For example, when I run a file with php -f <file> will the file be optimized with APC before executing or not? Presuming APC is set to load in config file. Also, will the scripts included with require_once be also optimized? I know optimization works fine when running in fastcgi mode, but I'm wondering if it also works in CLI. apc_* functions work, but I'm wondering about the code optimization, which is the main thing I'm after here. Happy day, Matic The documentation of apc.enable_cli , which control whether APC should

Using Silver Searcher, how can I search for: (non-binary) files with a word or pattern AND all filenames , with a word or pattern including filenames of binary files. Other preferences: would like to have case insensitive search and search through dotfiles. Tried to alias using this without much luck: alias search="ag -g $1 --smart-case --hidden && ag --smart-case --hidden $1" vincentleest According to the man page of ag -G --file-search-regex PATTERN Only search files whose names match PATTERN. You can use the -G option to perform searches on files matching a pattern. So, to answer your

I have a CLI script and want it to read data from a file. It should be able to read it in two ways : cat data.txt | ./my_script.py ./my_script.py data.txt —a bit like grep , for example. What I know: sys.argv and optparse let me read any args and options easily. sys.stdin let me read data piped in fileinput make the full process automatic Unfortunately: using fileinput uses stdin and any args as input. So I can't use options that are not filenames as it tries to open them. sys.stdin.readlines() works fine, but if I don't pipe any data, it hangs until I enter Ctrl + D I don't know how to

I'm looking for a command-line utility that will, at a minimum, render binary protobuf data in human-readable form. Filtering and selection options (along the lines of cut for text) would be nice, but the primary object is to make the data visible for debugging purposes. If there is no definitive tool for the job, links to relevant packages are fine. The Protocol Compiler -- protoc -- has this functionality built-in via the --decode and --decode_raw flags. This is the same tool you use to generate code from a .proto file so is likely already installed. For example: protoc --decode_raw <

I am trying to change the working directory of my Node.js script when it is run from a bin script. I have something like the following: #!/usr/bin/env node process.chdir('/Users') When I then run this file with ./bin/nodefile , it exits, but the working directory of the current shell context has not changed. I have also tried shelljs , but that does not work either. What is the best way to do this? I understand it's working but it's just in a separate process. The correct way to change directories is actually with process.chdir(directory) . Here's an example from the documentation : console

I have a profile activated by default in my maven setting file ~/.m2/settings.xml . Is it possible to deactivate it from the command line by doing something like this: mvn -P!profileActivatedByDefault Yes indeed, you have the right way. From maven profiles user guide Deactivating a profile Starting with Maven 2.0.10, one or more profiles can be deactivated using the command line by prefixing their identifier with either the character '!' or '-' as shown below: mvn groupId:artifactId:goal -P !profile-1,!profile-2 This can be used to deactivate profiles marked as activeByDefault or profiles that
