libreadline

问题 While using readline (blocking) for user input, I would like to output lines of text to the console asynchronously from another thread. Further, I would like that the readline prompt and current partial input line be removed from the console, the output line written, then the readline prompt and the partial user line restored - so as to give the appearance that the output was written "above" the prompt. By what combination of readline redisplay functions (or otherwise) can this be achieved?

问题 When using the auto completion with the Readline library in C, the prompt is reprinted when typing the tab key twice: (prompt) view NAME_OF_F (user presses tab twice) NAME_OF_FILE1 NAME_OF_FILE2 (suggestions by Readline) (prompt) view NAME_OF_F I'd like to suppress the reprinting of the prompt on the 3rd line by keeping the first line printed with the suggestions below it like such: (prompt) view NAME_OF_F (user presses tab twice) NAME_OF_FILE1 NAME_OF_FILE2 (suggestions by Readline) I'd like

问题 My application basically is a CLI with all the expected features like prompt, history etc., it needs to wait on STDIN for user input. For this I am using readLine system call. I have a created a network socket which is used to send the message read from user to server. My application is single threaded one. Because my application is blocked for user input, the socket created is not responding to keep-alive messages from server. I want to know if there is a way make readLine timeout after some

问题 I have tried everything I can think of to get this to work, to no avail so here I am requesting suggestions on how to debug. Firstly, runnning Ubuntu 11.10 Installed rvm: $ bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) Installed readline using apt-get: $ sudo apt-get install libreadline-dev Check for readline install: $ dpkg --get-selections | grep readline lib64readline-gplv2-dev install lib64readline5 install libreadline-dev install libreadline5

问题 I just installed posgresql with homebrew and when I go on to type the command psql I get the following error: dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.6.2.dylib Referenced from: /usr/local/bin/psql Reason: image not found [1] 69711 trace trap psql Does anyone have any idea about what's wrong? 回答1: I was getting the exact same error, but the above answers didn't work for me.

问题 After installing pyenv from Homebrew on MacOS Mojave I am getting build errors when attempting to install any python versions. When running pyenv install for any version the build will fail with error: dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib Referenced from: /usr/local/bin/awk Reason: image not found 回答1: The solution for me was to force link the readline 8 lib that I had under /usr/local/opt/readline/lib/ . > cd /usr/local/opt/readline/lib/ > ls libhistory.8

问题 I want a progress indicator that takes the output of a Perl system('make') and for each line output to STDOUT from the make command, I want to output a dot as a progress indicator. Unfortunately, I'm using the Term::ReadLine::Gnu Perl mod. How do I redirect STDOUT to capture and count the lines as the make command is running? 回答1: #!/usr/bin/perl my $command = "make"; open (my $cmd, "$command |"); while(<$cmd>){ print "."; } print "\n"; 回答2: make >& >(while read f; do echo -n .; done; echo)

问题 I am creating a server in python (what it is doing is irrelevant), but I would like it to accept telnet connections and provide a command line interface with line editing capabilities (tabcompletion, emacs/vi-mode, etc) and history per session. I have successfully created the telnet session, disabled line mode and enabled server echo. My initial thoughts were using readline but the python readline module seems to only work for a single session on stdin; and examining the underlying readline

问题 I am working on a rails app. Installed Postgresql using postgresql-9.1.2-1-osx.dmg Installed pg gem. Then when I executed rake db:create getting the following error - dlopen(/Users/sathishvc/.rvm/gems/ruby-1.9.3-head@knome-vivacious/gems/pg-0.12.2/lib/pg_ext.bundle, 9): Library not loaded: /usr/local/lib/libpq.5.4.dylib Checked if /usr/local/lib/libpq.5.4.dylib exists or not. It does not. So, it should be existing somewhere else in the system or I do not know, if I need to install any other
