kandi X-RAY | notcurses Summary

notcurses is a C library typically used in Utilities, Command Line Interface applications. notcurses has no bugs, it has no vulnerabilities and it has medium support. However notcurses has a Non-SPDX License. You can download it from GitHub.

Notcurses abandons the X/Open Curses API bundled as part of the Single UNIX Specification. For some necessary background, consult Thomas E. Dickey's superb and authoritative NCURSES FAQ. As such, Notcurses is not a drop-in Curses replacement. Wherever possible, Notcurses makes use of the Terminfo library shipped with NCURSES, benefiting greatly from its portability and thoroughness. Notcurses opens up advanced functionality for the interactive user on workstations, phones, laptops, and tablets, possibly at the expense of e.g. some industrial and retail terminals. Fundamentally, Curses assumes the minimum and allows you (with effort) to step up, whereas Notcurses assumes the maximum and steps down (by itself) when necessary. The latter approach probably breaks on some older hardware, but the former approach results in new software looking like old hardware. Why use this non-standard library?. Much of the above can be had with NCURSES, but they're not what NCURSES was designed for. On the other hand, if you're targeting industrial or critical applications, or wish to benefit from time-tested reliability and portability, you should by all means use that fine library.

            Argparse outputting help text twice
            Asked 2022-Feb-25 at 21:44

            After an hour googling, I can't find anybody who has had anything resembling this issue besides myself. I created a command line interface with argparse. Originally I had tried to leverage argparse's built in help text behavior. But my boss isn't satisfied with the default help text, so he is having me write up the full usage/help text in a text file and just display the entire file.

            For some reason, in a certain case, its outputting the text twice.

            Here is the basics of how my program is broken down:

            I have a top level parser. I read in my help text file, set it to a string help_text, and then set "usage=help_text" on the parser. Then I create subparsers (4 of them and then a base case) to create subcommands. Only one of those subparsers has any additional arguments (one positional, one optional). Before I reworked the help text, I had help text for each individual subcommand by using "help=" but now those are all blank. Lastly, I have set up a base case to display the help text whenever no subcommands are given.

            Here is the behavior I'm getting:

            When I call the main function with no subcommands and no arguments, my help_text from the text file outputs, and then like 2-3 additional lines of boiler plate I can't seem to get rid of. Also because the word usage appears in my text file, it says "usage: usage"

            When I call the main command and then type --help, the exact same thing happens as above.

            When I call the one subcommand that has a required positional argument and I don't include that argument... it spits out the entire help text twice. Right above the second time it prints, it prints the default usage line for that subcommand.

            Lastly, when I use a different subcommand that has no arguments and give it an argument (one too many) it spits out everything completely correctly without even the extra couple lines at the end.

            I don't know how to make heads or tales about this. Here is the main function of the script (I can verify that this problem occurs only in the main function where argparse is used, not the other functions that the main function calls):

            Solving conda environment stuck

            ANSWER

            Answered 2021-Dec-22 at 18:02

            This solves fine (), but is indeed a complex solve mainly due to:

            • underspecification
            • lack of modularization
            Underspecification

            This particular environment specification ends up installing well over 300 packages. And there isn't a single one of those that are constrained by the specification. That is a huge SAT problem to solve and Conda will struggle with this. Mamba will help solve faster, but providing additional constraints can vastly reduce the solution space.

            At minimum, specify a Python version (major.minor), such as python=3.9. This is the single most effective constraint.

            Beyond that, putting minimum requirements on central packages (those that are dependencies of others) can help, such as minimum NumPy.

            Lack of Modularization

            I assume the name "devenv" means this is a development environment. So, I get that one wants all these tools immediately at hand. However, Conda environment activation is so simple, and most IDE tooling these days (Spyder, VSCode, Jupyter) encourages separation of infrastructure and the execution kernel. Being more thoughtful about how environments (emphasis on the plural) are organized and work together, can go a long way in having a sustainable and painless data science workflow.

            The environment at hand has multiple red flags in my book:

            • conda-build should be in base and only in base
            • snakemake should be in a dedicated environment
            • notebook (i.e., Jupyter) should be in a dedicated environment, co-installed with nb_conda_kernels; all kernel environments need are ipykernel

            I'd probably also have the linting/formatting packages separated, but that's less an issue. The real killer though is snakemake - it's just a massive piece of infrastructure and I'd strongly encourage keeping that separated.

            By default, when you use mysqldump DB, the output includes table-creation statements, but no CREATE DATABASE statement. It just assumes you have created an empty schema first.

            Shell script to pull row counts from all Hive tables in multiple Hive databases
            Asked 2021-Nov-22 at 07:57

            I am trying to create a shell script that will pull row counts in all tables from multiple databases. All of the databases follow the same naming convention "the_same_databasename_<%>" except the final layer in the name, which varies. I am trying to run the following:

            use ; show tables; select count(*) from ;

            Since I have 40 different databases, I would need to run the first two queries for each database 40 different times, plus the select count query even more depending on how many table in the database (very time consuming). I have my PuTTy configuration settings set to save my PuTTy sessions into a .txt on my local directory, so I can have the row count results displayed right in my command line interface. So far this is what I have but not sure how to include the final commands to get the actual row counts from the tables in each database.

For example, I'm trying to write a function to clear the terminal (regardless of which terminal it is), e.g. echoes the clear command if in Git Bash, or cls if in cmd.

            Answered 2021-Oct-12 at 15:28

            Well, I'm not entirely sure what was wrong, but I think it came down to one process not finishing before another process started. I inserted a sleep 5 in the script - just before the last line where I'm trying to connect to the server, and that worked. I also wrapped the line in a while loop, giving it up to 5 attempts to connect to the server, and if it fails, it will wait a further 5 seconds. Currently this seems to work fairly reliably and I am able to connect to the MySQL server.

            So either way the problem appears to be solved.
