MBP のバッテリーが3時間持たなくなってしまった

こんなにへたるとは、つらい

バッテリー情報みられるんですね

これみると正常っぽいんだけど、充電し忘れただけだったのか？！

VS Code に PHP Debug 環境を構築したくなった。

はじめに

VS Code に PHP Debug 環境を構築したくなった。
四苦八苦しつつもなんとか環境ができた。
試行錯誤でどのような手順だったかはあいまいだが、うろおぼえの範囲で記録。

難所は pecl で xdebug がビルドできなかったところ。
原因とおもわれるところは

phpize が OS X もしくは Xcode に既定でインストールされているものが実行されていたこと
sudo で pecl を起動するとき、環境変数を引き継いで(preserve) していなかったこと

環境

kuwahara-mac:~ mitsuaki$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.14.1
BuildVersion:   18B75

How to Install XDebug on a new Mac (including Mojave) | Devin Baldwin

手順

xdebug ビルド

# link できないとエラーがでるが、後述の環境変数でフルパスで指定することで回避
$ brew install autoconf

$ brew install automake

# ソースからビルド(-s)しなくても大丈夫なのかもしれない
$ brew install php@7.2 -s

# brew でインストールしたpecl を使うために、bin ディレクトリへ移動
$ cd /usr/local/Cellar/php/7.2.12_1/bin

$ export PHP_AUTOCONF=/usr/local/Cellar/autoconf/2.69/bin/autoconf
$ export PHP_AUTOHEADER=/usr/local/Cellar/autoconf/2.69/bin/autoheader

# うえの環境変数を引き継ぐために、-E つきで起動
$ sudo -E ./pecl install xdebug

php.ini

$ head -n 5 /usr/local/etc/php/7.2/php.ini
zend_extension="xdebug.so"
[XDebug]
xdebug.remote_enable = 1
xdebug.remote_autostart = 1

httpd.conf

$ cat /usr/local/etc/httpd/httpd.conf | grep -E '^[^#].*(php|FilesMatch)'
LoadModule php7_module /usr/local/opt/php/lib/httpd/modules/libphp7.so
<FilesMatch .php$>
    SetHandler application/x-httpd-php
</FilesMatch>

launch.json
