# testcode

This is just a test project. You can do anything here, test g++, make, cmake,
git, cscope, and IDE projects.

## Getting the project

You can get a copy of this project by clicking on the
[ZIP](http://git.dlma.com/testcode.git/zipball/master)
or [TAR](http://git.dlma.com/testcode.git/tarball/master) buttons
near the top right of the GitList web page.

You can clone from the origin with:

git clone ssh://USERNAME@dlma.com/~/git/testcode.git

## IDEs

### tmux vim entr

Create two panes in tmux, run vim in one, and run entr in the other with a command like:

find . -type f $ -name \*.[ch]pp -or -name \*.[ch] $ | \
    entr -c sh -c 'ctags -R *; make -j$(nproc) && valgrind --leak-check=yes product/testcode'

or, to compile with debug info and run in gdb:

find . -type f $ -name \*.[ch]pp -or -name \*.[ch] $ | \
    entr -c sh -c 'ctags -R *; make debug -j$(nproc) && gdb product/testcode'

Tips: you can also run ctags and cscope, and in vim you can grep and use the QuickFix window with commands like...

:grep -rI searchterm .
    :cw

See [this QuickFix tip for sorting results by filename](http://git.dlma.com/dotfiles.git/commit/0cb566c53caf931c8b3f423dcfded4660b220cbb).

#### entr One-Liner for When no Makefile

[This entr command is handy](https://twitter.com/dblume/status/1421011043489255424) when composing interview questions without a Makefile:

ls -1 *.h *.cpp | entr sh -c 'g++ -Wall -std=c++17 -pthread *.cpp && valgrind --leak-check=yes ./a.out'

### Visual Studio Code and WSL2

Once you've got the [Remote -WSL extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-wsl)
for WSL, you can invoke Code from the WSL side.

code .

Or, if it's not in your path, something like...

/mnt/c/Users/$USER/AppData/Local/Programs/Microsoft\ VS\ Code/bin/code .

### Other IDEs

Look for the presence of their project files. They should work normally.

## Current Features

* Multiple directories for testing build systems and IDEs
* "make" essentially works.

## Is it any good?

[Yes](https://news.ycombinator.com/item?id=3067434).

## To Do

* Compare make vs. cmake vs. autotools
* Experiment with ctags generation

testcode.git

Another tweak to the entr one-liner.
