linux - How to take user input during install -

-

So when I create a Debian package, I can write a post-installation shell script which just works fine. Currently I have been configured to do this 

  echo "Please enter your MySQL database user (default route)" Read MYSQL_USER echo "Please enter the MySQL database user password (default route) "Read -s MYSQL_PASS DBEXIST = 0 cmd =" ​​create database loportal; use lportal; " (Mysql -u $ MYSQL_USER -p $ MYSQL_PASS -e "$ CMD") || ((DBEXIST ++)) if [$ DBEXIST -ne 0]; Then the "echo" setup has ended, but MySQL already has a lportal table, it can be from Liferay's previous installation. If you want a fresh installation of this bundle, please remove the lportal table and reinstall this package. "Fi

This works fine for Ubuntu, however, I can not get user input to work with RPM for Fedora Is a good way to get user input? What I think, RPM was not designed to be interactive installed. However, I can not see a better way of doing this.

Does the user automatically do not have any local MySQL settings automatically? Is there a way to find out? Otherwise, what's the best way to ask for user input?

OK I have given it without any real answer - basically what I understand, I have two options - a rapper script like a bind or CUPS. Although this is not considered good packaging practice, and I am still unsure that How to go about doing this. Just to assign default values% POST scripts, and create the first fern flag. The user launches the first software, it prompts you for the configuration settings.

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
