help: use a dedicated syntax to color shortcuts in a help text This avoids applying the default syntax, or the syntax specified with --syntax, to a ^G help text. 2017-04-25 13:41:35 +02:00			`## This is meant for highlighting key combos in a nano help text.`

syntaxes: remove quotes from each syntax name, and color it differently The different color will make the name stand out, as it should, instead of looking the same as all the regex strings. 2018-02-07 11:25:46 +01:00			`syntax nanohelp`

help: use smaller triangles for the arrows In Dejavu Sans Mono the old pointing triangles had a decent size, but in Noto Mono and in Ubuntu Mono (fonts that handle combining diacritics better) those triangles were massive, visually taking up more than a single cell, overlapping the closing parenthesis when they are displayed in the second column. Not nice. The new pointing small triangles look good in the Noto and Ubuntu fonts, but are real tiny in Dejavu. :\| Oh well, one can't have everything. (Other triangles are not an option, because they don't degrade to actual arrows when on a Linux console.) 2021-06-14 09:10:08 +02:00			color cyan "\^[]/4-8@A-Z\^_`◂▸▴▾-]" "[◂▸▴▾]" "\<(M\|S[Hh]-[Mm])-[^")”»“」]" "\<F([1-9]\|1[0-9]\|2[0-4])"
tweaks: renumber a couple of symbols, and reshuffle a bit of code Also, contract the regex for key strings. 2018-11-07 19:30:04 +01:00			`color cyan "\<((Sh-)?Tab\|Enter\|Ins\|(Sh-\^?)?Del\|Space\|Bsp\|Up\|Down\|Left\|Right\|Home\|End\|PgUp\|PgDn)\>"`

syntax: nanohelp: avoid colorizing M-) in (M-) and M-" in "M-" Instead of quoting M- as 'M-', some translations use «M-» (Catalan), (M-) (Croat), "M-" (Italian), „M-” (Romanian), or „М-“ (Serbian). Those occurrences of M- nor its quotation marks should be colored. Achieve this by excluding those quotation marks from the M- regex, and then colorizing M-) and M-" only when at start of line (first column of shortcuts) or when between parentheses (second column). 2021-05-30 10:28:42 +02:00			`# Colorize M-) and M-" only when between parentheses...`
