Using {, } instead of /", /', '/, "/ in the examples of my last post even would
improve legibility
even more:
This also makes it easier to use (unescaped) single and double quotes as
many times as one sees
fit within a string literal, e.g.
str= { this is a multiline literal using a "double", a ""double
double"", a 'single' or
\n\ta double ''single'' quotes without a problem } str= { this is a
multiline literal using
a "double", a ""double double"", a 'single' or \n\ta double ''single''
quotes without a
problem }
Additionally, it becomes possible to have block and line comments unescaped
in such a multi-line
literal, e.g.
say { this is a multiline literal that allows one to use 'single' or
"double" quotes within
the same string as well as /* comment-like */ text as well as -- double
dashes. \n\tthis was
a newline char followed by a tab char }
So for example a SQL-statement could be changed from currently (almost
illegible, example
extracted from a post to RexxLA):
sql_cmd = "INSERT INTO wp_posts
(","'ID',","'post_author',", "'post_date',", "'post_date_gmt',",
"'post_content',", "'post_title',","'post_excerpt',", "'post_status',",
"'comment_status',", "'ping_status',", "'post_password',", "'post_name',",
"'to_ping',", "'pinged',", "'post_modified',", "'post_modified_gmt',",
"'post_content_filtered',", "'post_parent',","'guid',", "'menu_order',",
"'post_type',", "'post_mime_type',",
"'comment_count')","VALUES(","'"gp.ID.1"',","'"gp.post_author.1"',","'"gp.post_date.1"',","'"gp.post_date_gmt.1"',","'"gp.post_content.1"',","'"gp.post_title.1"',","'"gp.post_excerpt.1"',","'"gp.post_status.1"',","'"gp.comment_status.1"',","'"gp.ping_status.1"',","'"gp.post_password.1"',","'"gp.post_name.1"',","'"gp.to_ping.1"',","'"gp.pinged.1"',","'"gp.post_modified.1"',","'"gp.post_modified_gmt.1"',","'"gp.post_content_filtered.1"',","'"gp.post_parent.1"',","'"gp.guid.1"',","'"gp.menu_order.1"',","'"gp.post_type.1"',","'"gp.post_mime_type.1"',","'"gp.comment_count.1"'",")"
to a better legible (less error prone) version:
sql_cmd = { INSERT INTO wp_posts ('ID', 'post_author', 'post_date',
'post_date_gmt',
'post_content','post_title', 'post_excerpt', 'post_status',
'comment_status','ping_status',
'post_password', 'post_name', 'to_ping','pinged', 'post_modified',
'post_modified_gmt','post_content_filtered', 'post_parent',
'guid','menu_order','post_type',
'post_mime_type', 'comment_count' )VALUES('}gp.ID.1{',
'}gp.post_author.1{',
'}gp.post_date.1{', '}gp.post_date_gmt.1{','}gp.post_content.1{',
'}gp.post_title.1{',
'}gp.post_excerpt.1{','}gp.post_status.1{','}gp.comment_status.1{',
'}gp.ping_status.1{','}gp.post_password.1{',
'}gp.post_name.1{','}gp.to_ping.1{','}gp.pinged.1{','}gp.post_modified.1{','}gp.post_modified_gmt.1{','}gp.post_content_filtered.1{','}gp.post_parent.1{','}gp.guid.1{','}gp.menu_order.1{','}gp.post_type.1{','}gp.post_mime_type.1{','}gp.comment_count.1{')
}
