atomを起動できない問題の workaround
atomを使ってみようと, Ubuntu 15.04に公式 debパッケージを使って, インストールして起動しようとしてみたが以下のエラーが出て起動しない.
line 98: 8076 Aborted (core dumped) nohup "$ATOM_PATH" --executed-from="$(pwd)" --pid=$$ "$@" > "$ATOM_HOME/nohup.out" 2>&1 [8076:0727/230141:ERROR:browser_main_loop.cc(170)] Running without the SUID sandbox!

[libprotobuf FATAL ../../third_party/protobuf/src/google/protobuf/stubs/common.cc:61] This program requires version 2.6.0 of the Protocol Buffer runtime library, but the installed version is 2.5.0.

Ubuntu 14.04ではなんともなかったのだが, 起動さえもできなくなってしまった. Protocol Bufferライブラリのバージョンについて怒られているが, インストールしているバージョンは 2.6台でそこに問題はない(はず).
Workaround
環境変数 GTK_IM_MODULE(KDE等の Qt環境では QT_IM_MODULE)と XMODIFIERSを無効にして起動すれば問題ないことがわかった.( 参考). 以下のようなスクリプトを /usr/binより優先される PATHに置き, 実行すればとりあえず起動できることはわかった. インプットメソッドは起動できないので日本語は打てないが, 必要ないのでとりあえずいいでしょう.
#!/bin/sh set -e unset GTK_IM_MODULE unset XMODIFIERS /usr/bin/atom $@
Implement my own simple helm-find-files
helm-find-files is useful command for opening files in current directory. However I have some complaints for it.
- I want to see only files, not directories(.
, ..
etc).
- I don't want to open binary files
- I use only some actions(open file, open file in other window, insert file)
Here is code. To collect files is following step
- Collect all files/directory in current directory by glob('* .*')
- filter them by -T
file flag
- -T
file flag returns true if argument is text file.
(defun my/helm-find-files-init () (with-current-buffer (helm-candidate-buffer 'global) (unless (zerop (process-file "perl" nil t nil "-wE" "say for grep {-T $_} glob('* .*')")) (error "Failed: collect files")))) (defvar my/helm-source-find-files (helm-build-in-buffer-source "Find Files" :init 'my/helm-find-files-init :action '(("Find File" . find-file) ("Find File other window" . find-file-other-window) ("Insert File" . insert-file)))) (defun my/helm-find-files () (interactive) (helm :sources '(my/helm-source-find-files) :buffer "*Helm Find Files*"))
This is a little slow because Perl is not so fast language :-(

quickrun.el 2.2.4 released
I released quickrun 2.2.4
This version fixes quickrun-shell
command. It was broken long time ago. Sorry I didn't realize it because I didn't use it. quickrun-shell
executes buffer with eshell, it supports interactive program which reads something from STDIN etc. Here is a quickrun-shell demo.
Please report me if you have any quickrun issues or suggestions.
