# 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/main)
or [TAR](http://git.dlma.com/testcode.git/tarball/main) 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. You probably
only need the `git ls-files` for `entr`, but I provide a bash command group with
`find` here so I can easily copy and change it as needed.

{ git ls-files && find . -type f -regex '.*\.$cfg\|local$'; } | \
    entr -c sh -c 'ctags -R *; make -j$(nproc) && valgrind --leak-check=yes product/testcode'

`find` could also have been `find . -type f $ -name \*.cfg -or -name \*.local $`.

To compile with debug info and run in gdb:

... | entr -c sh -c 'ctags -R *; make debug -j$(nproc) && gdb product/testcode'

Tip: In vim you can grep and use the QuickFix window with commands like...

:grep -rI --exclude=tags --exclude=cscope.* --exclude-dir=obj 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

Add git ls-files and change find predicate.
