history

问题 I'm trying to redefine the keys used to navigate the history when inside several commands accepting regexps and offering C-p / C-n history navigation. I'd like to use other keys, in addition to C-p / C-n. For example when using occur or replace-regexp , C-p and C-n can be used to go to previous and next elements. I've tried several things but can't make it work. I think I'm missing the "big picture" here. Which mode-map do I need to modify, when and how? Everything I tried failed. P.S: Note

问题 I have two Activities FirstActivity and SecondActivity. FirstActivity has an intent filter MAIN, LAUNCHER and DEFAULT. SecondActivity is just a normal activity and no other flags is set in the AndroidManifest. My application is C2DM enabled and when a notification is received a taskbar Icon is displayed and when clicked it opens SecondActivity. Arrival of Notifications has two scenarios: First, My Application is Already Running when notification arrived and second My Application is totally

问题 The reverse-i-search facility in bash is useful, but it is unlike most other bash commands in that it seems to be bound to a keybinding ( Ctrl + R ). How can a user trigger this facility using an alias or typed-in command instead? 回答1: The reverse-i-search function is actually a readline function (reverse-search-history) and not a bash builtin function (man builtin or see builtin commands in the bash reference manual). To my knowledge there is no way to call a readline function outside of

问题 I would like to search for a specific command I've previously used. Is it possible to do a free text search on MATLAB command history? 回答1: If you want to accomplish this in a programmatic and platform-independent manner, you can first use MATLAB's Java internals to get the command history as a character array: history = com.mathworks.mlservices.MLCommandHistoryServices.getSessionHistory; historyText = char(history); Then you can search through the character array however you like, using

问题 It has always struck me as strange that the C function "fopen" takes a "const char *" as the second argument. I would think it would be easier to both read your code and implement the library's code if there were bit masks defined in stdio.h, like "IO_READ" and such, so you could do things like: FILE* myFile = fopen("file.txt", IO_READ | IO_WRITE); Is there a programmatic reason for the way it actually is, or is it just historic? (i.e. "That's just the way it is.") 回答1: One word : legacy.

问题 I am developing an app with numerous Activities. I would like to create a persistent notification that (more or less) says, "AppName - Return to AppName" that will be present whenever my background services are running. Creating and disposing of the notification was no problem. Now, the user could be on any of several screens/Activities, leave the application, then want to re-enter the app via the notification. The problem is , the notification must have an intent, which launches a

问题 Why are regular expressions called regular expressions? 回答1: They are based on regular languages. 回答2: Why are they called "regular expressions?" Regular expressions trace back to the work of an American mathematician by the name of Stephen Kleene (one of the most influential figures in the development of theoretical computer science) who developed regular expressions as a notation for describing what he called "the algebra of regular sets." His work eventually found its way into some early

问题 i want to see the number of removed/added line, grouped by author for a given branch in git history. there is git shortlog -s which shows me the number of commits per author. is there anything similar to get an overall diffstat? 回答1: It's an old post but if someone is still looking for it: install git extras brew install git-extras then git summary --line https://github.com/tj/git-extras 回答2: Since the SO question "How to count total lines changed by a specific author in a Git repository?" is
