 Various tips how to increase your productivity (esp. in Linux).
-  * When using **Perl** at ÚFAL, we recommend using [[Perlbrew]] with shared perl interpreters (different versions) and shared Perl modules (which otherwise take several hours to install).
+===== Editors =====
-  * See [[Python]] for using **Python** at ÚFAL.
+Who uses which editor and is willing to provide a mini-training for new users (show config, favorite macros, highlighters etc.).
+Feel free to add your name and editor.
+  * **vim**: Ondřej Bojar, Ruda Rosa, Milan Straka (C++ completion, Python completion, asynchronous make), ...
+  * **emacs**: ?
+  * **nano**:
+  * **atom**: Martin Popel
+  * **Kate**: Jonáš Vidra
+  * **PyCharm**: Petr Bělohlávek
+===== Bash =====
+  * Use Bash auto-completion (''source /etc/bash_completion''). Some tools have plugins, e.g. many [[https://metacpan.org/pod/Bash::Completion|Perl tools]].
+  * ''export HISTCONTROL=ignoreboth'' results in bash history ignoring duplicate entries and entries starting with a space.
+==== Directory-local Bash history ====
+  * Ondřej Bojar prefers to store the history in each directory in ''.history-bojar''. See ''/home/bojar/diplomka/granty/cracker-2015/mtm-2016-organization/accounts-mtm16/bash-profile-for-ufal-accounts''
+    * Note that this creates the ".history-your-name" wherever you have write access and some ÚFALers are not happy with this. In addition everyone sees what you did (this may be useful, but be careful).
+  * Ondřej Dušek (''/home/odusek/.bashrc'') uses a variant more friendly to others, which saves the histories in his home (but does not handle renamed directories):<code>
+if [ -z "$USER" ]; then
+    export USER=`whoami`
+fi
+# Store all history with times and directories
+function store_history () {
+    history 1 | awk '($2 !~ "^[mr]?cd[0-9a-z]?$") {$1="_T="strftime("%Y%m%d_%H:%M:%S_") PROCINFO["ppid"] "_PWD="  ENVIRON["PWD"] "\t"; $2=gensub("^_T=[-_0-9:]*[ \t]* *", "", 1, $2); $2=gensub("^_P=[^ \t]* *", "", 1, $2); print;}' >> ~/.history-all-$USER
+}
+export PROMPT_COMMAND="store_history"
+# Grep history
+function dhist (){
+    DIR=`pwd`
+    command grep "_PWD=$DIR"$'\t'".*$@" ~/.history-all-$USER | tail -n 30
+}
+function hist (){
+    if [ "$#" -eq 0 ]; then
+        tail -n 30 ~/.history-all-$USER
+    else
+        command grep "$@" ~/.history-all-$USER | tail -n 30
+    fi
+}
+</code>
+===== Git =====
+  * [[https://github.com/magicmonty/bash-git-prompt|bash-git-prompt]] shows e.g. the current branch and status. Martin Popel prefers to configure it (in bashrc) with
+    export GIT_PS1_SHOWDIRTYSTATE=1
+    export GIT_PS1_SHOWSTASHSTATE=1
+    export PS1='[\t]\[\033[2;31m\]\h:\W\[\033[01;95m\]$(__git_ps1 "(%s)")\[\033[2;31m\]>\[\033[0m\] '
+  * [[https://github.com/jonas/tig|tig]] text-mode gitk but better
+  * read https://guides.github.com/, understand [[https://guides.github.com/introduction/flow/|GitHub flow]], check [[https://services.github.com/on-demand/resources/learning-path/|GitHub training]]
+  * learn [[https://help.github.com/articles/using-keyboard-shortcuts/|GitHub keyboard shortcuts]], esp. "y" for permalink to a given line (line range) in source codes
+===== Other =====
+  * When using **Perl** at ÚFAL, we recommend using [[Perlbrew]] with shared perl interpreters (different versions) and shared Perl modules (which otherwise take several hours to install and 6GB).
+  * See [[Python]] for using **Python** at ÚFAL.
+  * See [[internal:remote access]], esp. for byobu and mosh.
   * You **should not turn off** Linux workstations at ÚFAL, unless really needed (or agreed with it@ufal). In that case, try the standard ways, and if they do not work, try Ctrl+Alt+SysRq+[R,E,I,S,U,B] rather than plug out power cable. Mnemonics: "Reboot Even If System Utterly Broken", see http://en.wikipedia.org/wiki/Magic_SysRq_key#Uses
+  * Ondřej Bojar has implemented many [[http://www1.cuni.cz/~obo/textutils/|Text utils]], which he likes to use in his scripts and advises his students to do so as well.
+    * The web versions of the text utils are often older than the ones in ''/home/bojar/tools/vimtext'' and ''/home/bojar/tools/shell''
+  * [[http://mg.readthedocs.io/latexmk.html|latexmk]] can be used with ''-pdf -pvc'', so whenever you save a ''tex'' file, the corresponding ''pdf'' will be regenerated (and your pdf viewer will refresh). Other useful options are ''-interaction=nonstopmode -synctex=1'', see e.g. [[https://tex.stackexchange.com/questions/118489/what-exactly-is-synctex|synctex]]
+  * [[https://www.pdflabs.com/docs/pdftk-cli-examples/|pdftk]] for merging and splitting pdf files (and much more) from the command line
