However, I'd like to have parameters on the left (strings before the = sign) be right aligned like in this example :

 1 AC_BR_BONANZA Too many newlines in a row... spammy template 2 ACCESSDB Message would have been caught by accessdb 3 ACCT_PHISHING_MANY Phishing for account information 4 AC_DIV_BONANZA Too many divs in a row... spammy template 5 AC_FROM_MANY_DOTS Multiple periods in From user name 6 AC_HTML_NONSENSE_TAGS Many consecutive multi-letter HTML tags, likely nonsense/spam 7 AC_POST_EXTRAS Suspicious URL 8 AC_SPAMMY_URI_PATTERNS10 link combos match highly spammy template 9 AC_SPAMMY_URI_PATTERNS11 link combos match highly spammy template 10 AC_SPAMMY_URI_PATTERNS12 link combos match highly spammy template 11 AC_SPAMMY_URI_PATTERNS1 link combos match highly spammy template 12 AC_SPAMMY_URI_PATTERNS2 link combos match highly spammy template 13 AC_SPAMMY_URI_PATTERNS3 link combos match highly spammy template 14 AC_SPAMMY_URI_PATTERNS4 link combos match highly spammy template 15 AC_SPAMMY_URI_PATTERNS8 link combos match highly spammy template 16 AC_SPAMMY_URI_PATTERNS9 link combos match highly spammy template 17 ACT_NOW_CAPS Talks about 'acting now' with capitals 18 ADMAIL "admail" and variants 19 ADMITS_SPAM Admits this is an ad

Any idea how to achieve this?

  • @Drew not really, fill-paragraph will add new lines, which I don't want. Commented Jun 2, 2022 at 9:15
  • @Drew This is not a duplicate of "How to right align region and/or line?". There the full line is right-aligned, but here only the part before the ?= is right-aligned. Commented Jun 2, 2022 at 14:24

You use the "complex align"-form of align-regexp, i.e., call it as with universal prefix argument C-u M-x align-regexp RET.

Use \(\s-*&[[:alnum:]_]+\) as regexp and -1 as group number. The negative sign means "justify" instead of "align".
With "align" the full group is replaced by the right amount of spaces whereas with "justify" only the space in the group is used for alignment but not the nonspace characters. If the space is at the beginning of the group that causes the right-alignment of the nonspace-part of the group.

For the other prompted arguments, choose the appropriate amount of spacing and deny repetition.

  • regex : \([[:alpha:]_]+\s-*\), group -1, spacing 1, repeat : n, result : gist Commented Jun 2, 2022 at 9:23
  • @ychaouche Sorry, I used your last example for testing (first left-aligned everything and applied align-regexp afterwards). I have adapted the regexp for your first example now. Could you try again? Commented Jun 2, 2022 at 10:00

    @ychaouche Please use Emacs to check the regexp. E.g., paste the text into the scratch buffer and call re-builder. Set reb-re-syntax to string via C-c TAB (you can use TAB-completion there) and paste the regexp from the question within the quotes "". Commented Jun 7, 2022 at 7:58

    @ychaouche Note also, that \s- depends on the syntax table of the major mode of the current buffer. Commented Jun 7, 2022 at 8:15
