latex code to word , libreoffice

In LyX, export (匯出) "MS Word Office Open XML". Then open it in word.
In LyX, export (匯出) "OpenDocument (Pandoc)". Then open it in libreoffice.

Break the long in-line math

If the in-line math contains too long expression, e.g, parenthesis, just add an math space in between the equality and the left parenthesis. Then the line will be broke at the math space. The following graph is the lyx source:

Note that there is math space. The following is the pdf graph.

Or put  \allowbreak in the place for breaking line, e.g.

Copy drupal from kpchiaoi5 to kpci7

In kpchiai5:

1. mysqldump -u drupaladmin -h localhost --skip-lock-tables -p drupal > drupal_20160826_kpchiaoi5.sql
2. gzip -9 drupal_20160826_kpchiaoi5.sql
3. sudo tar zcvf public_html_drupal_20160826_kpchiaoi5.tgz public_html/drupal

In kpci5:

1. download from kpchiaoi5: drupal_20160826_kpchiaoi5.sql.gz, public_html_drupal_20160826_kpchiaoi5.tgz
2. gzip -dc drupal_20160826_kpchiaoi5.sql.gz | sed -e '/^UNLOCK/d' -e '/^LOCK/d' > ~/a.sql
3. Using phpmyadmin to drop all drupal tables.
4. mysql -u drupaladmin -p drupal < ~/a.sql
5. sudo tar zxvfp public_html_drupal_20160826_kpchiaoi5.tgz -C /home/chiao
6. sudo chown -R www-data.www-data /home/chiao/public_html/drupal (IMPORTANT!!!!)

Prevent dash on the repeated author for IEEE bibliography

The following might not be work. Try my another blog:

https://kpchiaoo.blogspot.com/2019/07/bibtex-citation-with-author-for.html

1. Put the following line inside bib file, @IEEEtranBSTCTL{IEEEexample:nodash,CTLdash_repeated_names = "no"}
2. Put the TeX ERT inside lyx file contains
   \bstctlcite{IEEEexample:nodash}
3. Make sure "nodash" in both files are the same
4. Or edit IEEEtrans.bst, change # 1 to #0 as follows:

   % #0 turns off the "dashification" of repeated (i.e., identical to those
   % of the previous entry) names. The IEEE normally does this.
   % #1 enables
   FUNCTION {default.is.dash.repeated.names} { #1 }
